great system, I had a 16,000BTU heat pump Marine Aire unit, using a 12v raw sea water pump to circulate water over the condenser copper lines to remove the heat. This kept our 32' Sea ray sundancer entire cabin nice and cool when it was 95 degrees outside. The condensate would drain thru a tube into shower drain compartment with auto float switch.
Hi Clark I’m a disabled sailor in the UK first I WANT ONE please. The ready to go option would be good for me but if you can’t post with it all ready charged total understand, do what is best & we will charge it over here. Clark so sorry to hear about Emily & yourself, I had hoped you guys would go on forever as we do in relationships but I’m here & I have no doubt a lot more support from others watching the channel. You are an inspiration & and amazing person. I would be happy knowing half of what you do & I love learning. Best regards Chris Hobday
I always enjoy your videos and find it hard to believe that you guys don’t have over 100k subs yet. You produce good content and also information on what the sailing life is really like. Good luck and safe travels.
Thanks. I am getting discouraged about our view numbers. Other channels with fewer subscribers get 5 times our views. Maybe we should just film kittens and puppies.
@@Clarks-Adventure You've said it yourself, other channels do entertainment - you are creating a treasure trove of educational content. Your videos are targeted at those already living a sailing life or who are serious about doing so one day. This community will keep going back to your videos as a library of indispensable knowledge. Please don't get discouraged by the numbers - and know that you're creating 100 times more value than kittens and puppies. Keep up the good work!
@@Clarks-Adventure I've seen those other boating adventures where they literally hire young 19 year old models in string bikinis to dance around on the deck. Throwing champagne in the ocean...laughing drunk. lol, you two are too responsible, too crafty, too serious.....those other boating vessels are FAKE, yours shows reality. better to have a good solid normal subscriber base.
The quality of your viewer market can easily trump the quantity of eyeballs simply seeking entertainment. You said yourself that you weren’t interested in creating a business these days. They are. They have a sailing entertainment show business and must keep up the entertainment value with puppies, bikinis, exotic locations galore etc. It’s how they are making a living. Seemingly you already did all that business stuff and set it up so now you get to make only the videos you want to make without the pressure of feeding your “video monster”. …. Just saying.
@@Clarks-Adventure IF you want more views… You just need to be more playful with the thumbs. The thumbnail picture should be an overhead picture of you lying in bed uncomfortable. The text on the thumb should be: Stop sleeping in your sweat. That alone will double your clicks. The video title needs to be expanded to "Battery-Powered Air Conditioning on a sailboat." The content is great! Don’t change a thing with that. Just have more fun with your thumbnails.
Love the proof of concept! Thanks for posting this and the potential to acquire the goodies to make our own. I filled out the survey and I'd be open to all 3 choices... The DIY Kit may be the most versatile as I plan to apply it to my Class B Sprinter van RV for my land adventures. My pup/co-pilot will appreciate this when I have to leave him in the van on occasion. Boat comes soon... 2022!
I wish I had seen this before I retired from the transportation business. Now I live on a houseboat plugged into shore power. I put a rooftop RV unit on the roof of my truck, since the OEM compressors were always going out. It worked great, but took a lot of power (2 alternators @ 270 amps each & a 5,000 watt RMS pure sine wave inverter). I wanted to develop a no-idle battery bank system, but never found a system that would be practical (too many batteries; space & weight limitations.) A low power system like this one that did the job would have been the answer. I've thought about pumping water through a heat exchange unit with a fan on my houseboat to augment my two window units, since they struggle when it gets into the 90s. Great videos, keep up the good work, Sir! 😊
The time slots I wish everyone did... saving precious time is essential! That's the first time I've seen a survey on a UA-cam video so that's pretty cool thank you for the time you shared with us. And looks like a really small unit! The amps and the Watts and it uses is incredible but you already knew that
I saw where a person ended up grafting a mini split onto their boat. They made a cabinet to cover the outside unit to make it look better but was still able to ventilate. Their draw was 850 watts to cool and it came with a soft start to make it run from an inverter.
@misham6547 it should be just fine. It's made from the same metals your refrigerator is except for the condenser which is titanium, which seems to be the best for salt water. I've run the prototype for 5 years now.
Pleased to see that you were serious and still responding to comments. Great-looking idea and I am buying an air conditioned boat tomorrow I will see how the existing system works and if it is not up to speed I know it is marine ACDC and I will look up further on the internet now Best wishes to you and lovely to see a great idea pursued so enthusiastically
Survey done- I love your videos on how to- and all the other ones too. Definitely interested and looks simple enough for the average Joe for the DIY part. Keep them coming and stay healthy both of you. Cheers from Montreal
Clark, fantastic thinking and inventing! I love it! I have a 1973 Challenger 32 that I live on in Florida (St Pete). I have a really old Marine-Aire unit that was working 2 months ago, but has a leak. I'm planning my cruising for next year and looking at a new Dometic keel cooler unit (12-16k btu) but then I'm stuck on shore power or a generator or my inverter. I've got 200 watts solar now but could go as much as 800-1000. I'm also ready to pull the trigger on LiFePo batteries. I've filled out the survey, please keep me posted!
This is extremely cool and I hope your offering this when I'm finally able to buy my boat and hit the water. I'm about a year out from that yet finances willing and would definitely be interested in two or even three of these units for different spaces on my boat. As long as it isn't to crazy expensive that is. This would also help me when I can finally buy my dream in being able to pick a boat that may not already have AC on it and could save me a ton of money. So thank you for making this offering and like I said I hope it's around in a year or so when I know exactly what I need. Fair Winds and Safe Travels, God Bless...
I am very interested in the concept and product, but it will be at least a year before I would want to install one. I will check back after I purchase a boat! Keep up the good work on these awesome videos!
I'm currently building a cargo trailer to camper conversion, we decided to use a Pioneer Mini-Split. We will know in a couple weeks about the wattage numbers and efficiencies. Specs show about 330 watts on the lowest setting, and about 1300 watts on highest. If we can't dial it down low enough to run on solar, we will order one of your systems to add as a sustainable 24/7 system! Great Videos!!!
I Love the concept, and I have to agree, that sleeping comfortably in the tropics, or subtropics is quite the challenge on a boat, or offgrid. I have filled out your survey to possibly adapt it to RV boondocking, or grid down scenario. I'm also looking to install on a small boat to camp in while in The Keys. Kudos for sharing your innovations...
Amazing you are the first to look at s all room AC on boats that I efficient enough to run on batt power sourcing parts and developing a working model makes you a genius cheers to you
I need this. I want it, it's 4:44am and I'm pouring sweat, my bed is destroyed, if I don't get one people in space will be able to smell me. I've been in Florida for 21 years and I have not acclimated (acclamation is a myth). I don't know which kit I would use, but if it's a bucket of parts the bucket will need drainage or it will fill with sweat before I'm done putting it together.
Yes Florida is special. I've lived there as well. It gets cooler as you go south of key west. The DIY will be available first. Fill out the survey in the description to stay in the loop.
Hi Clark, this is just amazing. We are moving back onto our boat in Greece having just had our first baby, and the only thing holding us back is the heat in the boat at night! We have a beautiful CT41 ketch but she retains the days heat so much, its like a sauna at night, so we completely agree with you on this as an issue! Now we have a newborn to look after as well so we are very very keen to get a hold of one of these! Sadly though, we will have to address our battery bank and solar first... Still in the dark ages with the Lead Acid bats...
Thanks Matt The AC units are now available at MarineDCAC.com once you get your system up to scratch. Do you know about my BankManagerPlus? www.emilyandclarksadventure.com/bbms It and a Lifepo4 battery or two and you are good to go. No need to change anything in your charging system.
I´m really interested in this option (and has filled in the form), but I also contemplate an even simpler version where one can attach tubes to and from one or two sleeping bags and only cool and dehumidify the air inside the sleeping bags.
One month away from owning a 1972 Bristol 38 and I really enjoy your videos. As soon as Im a sailboat owner I'll be more than a subscriber. Im hoping for 800W of solar and 2x 18KW banks of 48v LIF04 batteries. Once I get that dialed in I am going to want to discuss AC & refrigeration with you. Keep up the great work.
Clark you are the man! You might remember that you helped me rig up a mast head tri light with only two wires and a couple of diodes added to the light. Circa 2000 in Mexico. We used that light for years until LED's were available. I love this AC idea. We could have used it in Borneo/Malaysia/Thailand. Though we survived without AC at anchor. SV Green Ghost. Great to see you again!
@@Clarks-Adventure We cruised from 2000-2004 Vancouver - Australia. Then relaunched in 2008 in Australia while I worked there for a couple of years. We left OZ for Indonesia/Thailand in 2010 and by 2017 we arrived back in Canada via South Africa. Back to work in 2017 but managed a three month break on Great Lakes this summer. Getting a new engine, paint job, another sail - etc. You know the drill. More cruising for sure. We've done about 40,000 miles. We need a break from cruising every 5 years to reset our brains and do something else. Anyone tuning in to your channel who reads this - BEST THING EVER! Go cruising.
I just found your channel through “Lady K Sailing” a few weeks ago & LOVE your stuff! I started watching them all from the beginning, Please keep up the GREAT CONTENT!! Gary…
I really like the full DIY option, and I would go so far as saying separating the parts so someone could purchase just what they need would be handy as well. For example: someone may want to buy a couple compressors and condensers, but use different evaporators. I am very interested in the compressor alone, because I have a different plan for using it.
Great video. I’m Offgrid and my 5000 btu Air conditioner uses about 38-40amps and I have enough solar to cover that it needs a lot of battery for the night so this would be a cool option for night time.
Hi Clark just subscribed you look like a great channel. Your AC vid is super interesting. I am thinking you should also connect to the #van life community as many are searching for something similar and like sail boats space and electrical consumption is at a premium. Most van people have insulated their vans so your unit would be really interesting. Most van self builders would probably do some of the assembly but not complicated wiring etc although some are brainiacs and could assemble a spacecraft in their garage hahaha
Parts for the kit are coming from the manufacturers now. New products on the way Check out MarineDCAC.com to get on a mailing list and as soon as parts come in it will become an order page.
Clark, I want one! I have a land sail boat, some folks call it an RV. I can totally see this working with taking the edge off at night. It's a tiny one and an older one that has a massive following made by Toyota! So excited, this is awesome
I remember when that compressor came out about 11 years ago. I was blue back then, I can't recall the name of the company that sold it, but it was extremely expensive going for $1,200 just for the compressor alone. The capacity was incredible and was advertised as being able to run an AC and well as a refrigeration system at the same time. Also, setting it up to run was rumored to be beyond the ability of the average person. China came out with a black knock off which runs for about $200 which looks a lot like the model you have. The key I think is to have it pre-charged and on a skid ready to be connected to pre-charged lines like the Cool Blue refrigeration system.
Clark, first off I'm not trying to step on your turf. I'm "retired" too. What follows is a story of air conditioners on boats. I think it may be worth a read. I'm in Texas and kept a roomy old 23 sailboat on a lake here. My wife and I loved spending the weekends out on the boat spending nights at anchor in a cove. On summer nights it became intolerable for her. One summer I took a sabbatical (semi-voluntary) from working and spent a lot of time on the docks. I'm a geek, lots of physics/chem schooling, and was pondering how to cool my boat w/o running a genset. One day I got a new slip-neighbor. Nice guy, we became friends (i.e., I recruited him as racing crew). Turns out he owns a small air conditioner company building specialized industrial AC units. Interesting... I pestered him with questions about component availability and told him what I was considering. Did he know companies I could look to for components? The next weekend he showed up with a box of the parts I had asked about basically just a heater coil, blower, and a certain type of mechanical thermometer. I built what I later learned is called an ice bank air conditioner. I filled an insulated tub with lots of ice and pumped water over the ice with a tiny live well pump. The mechanical thermometer cycled the pump on and off to maintain a water temperature of about 50F flowing through the "heater" coil. The blower blew cool air into the V-berth. Using that small blower this would provide cooler and dehumidified air to make the 90F Texas nights tolerable for about 6 hours on 50 pounds of ice using one AGM battery that also ran the anchor light. This was the days before lithium. Not high tech but it worked and I shared my math with my new friend. He responded with a job offer. I signed on and went to air conditioner school. 25 years later as a partner in the business we received an offer we could not refuse and sold the business, retired in my 50s. That offer was significantly inspired by the self contained lithium powered AC system I had designed. Naturally there is a non-compete and IP I sold so there is much I cannot discuss. What I can say is that you are on the right track. What you really want to do is better manage your air flow so you can eliminate the fans. Using an efficient BLDC blower that runs whenever the system is on and only cycling the compressor as needed is more efficient. Sleeping in a boat you only need cool air to the face and upper extremities to be comfortable (enough). Think of where a car AC blows, face and hands. Cooling the walls and ceiling do not add comfort but you are totally correct that the air must be constantly moving. BLDC blowers aren't cheap but from China they are less than two $100+ fans and use less power. There must also be _some_ source of fresh air. Humans exhale 20,000-ish PPM CO2 (top of my head number) and begin to show symptoms (drowsiness, discomfort) at about 1,500 PPM. you don't need much fresh air but in a sealed space you need some. If you turn your car onto "Recirc" is still pulls in that minimum. Remember it was CO2 abundance, not O2 deprivation, that almost killed the Apollo 13 astronauts I have chartered cruising boats that used automotive style compressors belt driven from the engine to keep the fridge cold plates frozen with a few hours of engine time in the morning. If I were outfitting a cruising boat today I would seriously consider using a similar system to freeze water for cooling cabins later in the evening. Webasto in Europe markets a system like this for use in the sleeper compartments of big semitrucks after a long day of driving. Those components may well be appropriate for use on a yacht. For me the fascination with ice bank air conditioning stems from the simplicity of rejecting heat when energy is abundant and absorbing heat when it is scarce, kind of like a battery but without so many inefficiencies. Yes, low temp refrigeration is less efficient that high temp AC but that is offset by use of a water cooled condenser. I might consider using a more efficient brazed plate heat exchanger for a condenser and a secondary coolant loop to put the heat into seawater, but that may be overthinking the issue. Application specific observations: The block type TXV in your air handler is poorly calibrated for your compressor capacity (if it is calibrated at all, most are junk). United Refrigeration dealers can help you choose a better one. The small compressor you are using contains little lubricant. If air conditioning a V-berth or other area further from the compressor consider using a _properly sized_ oil separator before the condenser to prevent oil starvation. Adding extra oil to the system must be done with real caution. There is more than fits here to that subject.
@@Clarks-Adventure With a good externally equalized high temp valve, 7-ish degrees superheat (Sporlan brand, right refrigerant and capacity) you may be able to run your compressor more slowly and are far less likely to have the compressor fail early.
@@briansb2455 this unit is not the original milspec one. It is a Chinese reproduction at about 1/4 the price of the original. Still quite efficient, but not a $1200 compressor.
You need to fill out the survey to be informed. We are building a webpage now. I don't think you would want that as you would have to move the water lines. But to do that you would get the kit (which will be available first) and set it up any way you want. Personally I'd just duct the air. There are 4 flanges on the air handler you can connect to duct work.
Thanks. I just installed the first production unit in a friend's boat. Went well. It's at the end of this playlist. A/C and Refrigeration: ua-cam.com/play/PLsT7_jPsZM5qNlstuF-fdlgjrimo18tq7.html
Saw a video on UA-cam a week ago someone had a 12-volt air conditioner in a small RV said it worked great just saying. Cost was about $2000... great video thanks for posting.
@@dereknolin5986 , Just got a new phone, still setting it up. Trying to find it the other night and couldn't. I found it the first time by asking on my phone, 12-volt air conditioning videos on UA-cam and it came up. Wish I could be more help.
Hey, I do not know you or your channel but this popped up in my feed. I am a maintenance tech at a factory and we have these super small air conditioners that cool down electronics cabinets. These are bigger cabinets than you are imagining though, maybe 2 feet deep by 8 feet high by 12 feet wide, but I am sure there are larger cabinets out there. People could probably size one to whatever size cabin they have if DIY is scary to them. Using saltwater over air for heat exchange is smart though.
Those small rotary compressors are compact, but the linear compressor while bulkier are even more efficient. I was googling 'water medium mini-split a couple days ago, and all kinds of variations to see if anyone used water to pass cold from compressor to indoor unit and found nothing. Then youtube recommended this, and I see someone has done it! I was thinking antifreeze, but salt water can go below 0F, good enough for a/c, but not so much for a freezer.
Seattle's never hot !? we were there on our 4 corners tour, and it was 113* for three days on the record breaking heat wave ! Loved the area though! great vid! I' glad you found a way to keep cool!
Great Job. I’m interested too! I’ve built regular units but I’m fascinated by the little compressor. I’ve put a lot of thought into solar a/c for my sailboat too. You did an awesome job of making it.
Great air conditioner Clark, Hope it all works out for you, And if you would like to expand the demographics you could always talk to campers, Or even camper manufacturers they would probably be very interested
Absolutely Brilliant the thinking you have been doing and the mission you went to find what you thought was invented. I literally just saw a company come out with a 12 volt. Must me the same as you were thing. You have an awesome mind to create. I love hearing ideas they are exciting to grow on. 👍
Glad to have you sharing this “cool” (your words) idea. Very interested. Will have this over refrigerator. BTW, We were just fine for winter in Bahamas without fridge. Rum not beer. Meat where available. Don’t drink milk. Ate last nights leftovers for lunch next day. Most things in fridge don’t need to be there. We never had butter, Mayo, pickles, eggs, open cat food, ketchup, real maple syrup, mustard, cabbage, carrots. Nothing wrong with many things from a can. Didn’t suffer, wife creative cook.
@@Clarks-Adventure I filled it out. Along with the AirCon I think I’d like to have a water maker, still before refrigerator. No one ever said I was normal.
We’d love one! Even in the summer it’s fairly cool in the evenings here on the west coast of Florida but we have plans to cruise further south so we will need something! We’d like the fully assembled and charged unit.
Hey Clark, this is Remco from all over Europe. I watched your videos again now that I have bought a catamaran. It already has 2 ac for 2 cabins each. What I like to know is if it’s possible to compressors on one system? Than I can cool high power with the generator for a our and than switch over to low power on battery. Also like to talk about eddying Lithium to lead, ore making a new bank just for the ac. Please let me know how to connect? Thanks for your content!
So let me preface this with I have fallen in love with heat pumps. Now, my ten year plan involves selling my condo (once its rebuilt from the fire of course) and then buying a boat and moving aboard. Keep in mind I live in New England (Massachusetts actually). So heating my boat is a high priority for me. I am exploring all options on this front, including diesel heaters with radiator pipes leading through out the boat (including under cabinets and bunks and even the lockers) to prevent frozen pipes and the like. I understand you not caring a hill of beans about heat because you’ve given it up for tropical settings. But I just watched an interesting video on heat pumps and in it the video stated that central air systems have 95% the same components as their heat pump cousins. So then the whole process of how a heat pump worked and how it was the same process as air conditioning only there was a reverse feature added that could turn your evaporator into a condenser and vice versa. So naturally, that got me thinking about your system. Why? Because I have a curious mind I guess or because I do enjoy understanding how things work. So, my question is, since you are running your ac only at night, wouldn’t it be better to build a structure outside for your condenser to dump the heat energy your system creates? And how how difficult would it be to convert your system into a heat pump, so it could both heat and cool off batteries?
It does dump the heat outside the boat and there will be a reversing cycle version. Also the air handler I use has a heater core inside it that you could run that hot water through.
This is very interesting, survey completed. I would definitely be interested in a unit, maybe two, so hopefully you will decide to bring something to market.
What I'm gathering here, this is a great way to combine old and new systems as money allows. You didn't go detail deep in this but it seems to me that this should be marketed as a lithium only device as well. I'm not studied well on the big three's charging strategies but I don't think anyone is doing this. I hope you've applied for a patent.
Yep I have a patent pending. Strangely the patent office takes UA-cam videos as proof of "prior art". So even this video protects me. No this requires lead. Or at least another reliable bank if batteries. That bank can actually be tiny.
It's still up in the air but I'm thinking $200 and $300. That might include the contactor, might not. Supply chain is a mess right now. A chip that should cost a dollar is now $9.00 and it's big and better brother simply isn't available. So once I get through the software I'll see what chips I can still find and start production on the new boards. Announcement: I just sat down to answer these messages from all day in my lab. I have a bbms+ prototype that WORKED. Single first test but everything worked! Seemed a good time to kick back for the day. You are the first to hear.
@@Clarks-Adventure I'm a freshwater fisherman and RV guy that does everything DYI so sailing channels fit me well. So... You're helping the RV world as well.
Angry pixies are angry pixies. You RV guys actually need it most as you all have a lead starter battery anyway and can't carry weight as well. My parents do the RV thing. Let's just say they are proud of their power system when they chat with people in the park. Their rigs have always benefited from my lab bench.
I just bought a boat with something very much like this installed. It doesn't appear to be stock as it looks brand new mounted on new lumber in a 35 year old boat. The ducting is run for the most part, and it seems to all be there. I'm lucky I have a friend that is an HVAC specialist and says he can get it going no problem, and parts are everywhere. Fingers crossed 🤞
Watts are never "per hour" unless one literally means that the power consumption is increasing constantly over time. In ten hours, so by morning, you'd be drawing half a kilowatt. You probably meant it draws 50 watthours per hour (50 Wh/h), which is a 50 watt average power consumption due to drawing more (185 W) when it does run but having that 28% duty cycle once the temperature set point has been reached. That match checks out by the way: 185 W * 0.28 = 52 W so it's bang on. That's a good system you've got there! It's doing the most with the least invested in terms of money and consumed in energy over its service life, and you know exactly how it's put together! Major kudos.
Yes you are right I should have said 50 or 60 watt hours per hour average. I think most sailors think in amps so the 14 is a more important number. (Note NOT 50kWh/h). We all make mistakes. :) Thanks for appreciating my work. It still shocks me it works for so little power.
This is great. From what I've seen out there, a brilliant ground breaking innovation. I've been cramming to learn about solar. I use thermo dynamics to cool my house. I heat one room in winter to save money. My body prefers a warmer climate. I've lived around the world. Always need a way to cool off to survive though. I might end up living in a box truck I'm working on, needs some help, 75 Dodge CB300, but in a boat in Florida or NC would be great. Might end up in a subterranean hovel in the desert. I'm somewhat disabled, rehabbing from a brutal life. I see a lot of people who could use this, just to make a cool place to survive. I'm very handy, but not too smart on AC systems or electrical. I test as genius, but I know I'm stupid in some areas, lol. Brilliant in others. If this is dependent on a massive source of water that would limit the possibilities, if not the applications could be huge, wide and deep. I know I'm going to need this. Don't know if I'm going to be able to afford it for some time. I have an idea what the battery and solar system will cost. I think if your system creates dry air, a small evap system could cool as augmentation, but there goes the dry air, poof, lol.If it dries efficiently enough, using with seperate evaporative cooling might be synergistic (just need a fan and water flow, which is low volume and can be done by gravity by suspended tank) though usually that sort of synergy gets blocked by reality of physics, but sometimes it can be great. If your system would work in a desert with a small water tank, the combination would be almost a no brainer.
Thanks. Nice of you to say and astute of you to notice. Yes it can work with air cooling. You need to spend more power on a fan and the compressor needs to work harder though. No the swamp cooler doesn't help. You should look at the chemical dehumidifier AC that "Tech Ingredients" showed in his video. I think you might really like to watch that.
Good to know. Have you filled out the survey yet? That's the only way to be in the list Also, should be available very soon. For kit form with fill system coming soon after.
Newly subscribed. I love this video ! I'm not great with the back and forth from C to F (I'm 71), but you are fun, and i like engineer inventor energy!
Clark, I want one. I'll be buying a boat this winter/spring, and yes.. I want one. I'm saving this video, I'll email you after I start adding gadgetry.
Clark, Hey thanks for all of the great experience you share with us. I am a retiring controls engineer and the advice you give to the cruising public is just excellent. I bought the AC unit you talk about in this video and it will likely be installed in a few weeks. Looking forward to reaching out to you directly about it but don't have a patreon account set up. Can I just support you via Paypal?
Nope I can't. I sold the design to a manufacturing company. Besides the compressor isn't available to the general public. If you fill out the survey you will be informed when kits are available.
Seen those compressors on Chines website 12V variable speed mini scroller. Nice to see one in use. I am quite impressed with the duty you got out of it. As an RV person my self. As a fridge engineer by trade that has an all round understanding of Solar batteries and inverters etc. After watching this video considered if using just cold sea water running through a finned heat exchanger in your cabin would be enough. But looks like in your part of the world the sea temperature reaches 26C So would not be very effective.The sea temperature in the UK is between 8C-17C and would work well. But inversely our climate is not as hot as the tropics.
It's actually a different compressor. Wish I could use the Chinese version as they are WAY cheaper. This one was developed under a DARPA contract. Although it looks the same. The Chinese claim a COP of 3 for their unit. Mine claims a COP of about 8. And since their only client just now (besides me) is the US military I believe their claims.
Thanks Brad, The guy I contracted the AC unit to says he will have a web page up soon. Fill out the survey and I'll notify you when he gets it done. Had what seems like a final breakthrough today on the bbms+. We are happy with it's features and it seems to be working well on the test boat. I'll be ordering the final (for sale) boards very soon. Hope I can find all the chips I need. Parts are getting scarce out there.
I want One. and I'd like to include it in my growing product lineup. I cater to people with small sailboats - typically under 30 feet who want some of the ease and pleasantries that larger boat owners enjoy - without the big boat expense. I'm also developing a plan to convert a SeaRay 270 into an electric propulsion trawler. I've been following SV Uma's success and am blown away at how far north they are operating. I'm intrigued with your low power consumption DC compressor as the last thing on my project list is to dump the ICE generator. I already have a working boat AirConditioning system installed but the system runs on 110AC supplied by the generator. PS - I live and work in Phoenix AZ.

great system, I had a 16,000BTU heat pump Marine Aire unit, using a 12v raw sea water pump to circulate water over the condenser copper lines to remove the heat. This kept our 32' Sea ray sundancer entire cabin nice and cool when it was 95 degrees outside. The condensate would drain thru a tube into shower drain compartment with auto float switch.
Hi Clark I’m a disabled sailor in the UK first I WANT ONE please. The ready to go option would be good for me but if you can’t post with it all ready charged total understand, do what is best & we will charge it over here.
Clark so sorry to hear about Emily & yourself, I had hoped you guys would go on forever as we do in relationships but I’m here & I have no doubt a lot more support from others watching the channel. You are an inspiration & and amazing person. I would be happy knowing half of what you do & I love learning.
Best regards
Chris Hobday
Thanks Chris.
The unit in the video is available at marineDCAC.com now. Stuart, the guy running the AC business is working on an all on one unit.
Agree I hope they can make it work out again
I always enjoy your videos and find it hard to believe that you guys don’t have over 100k subs yet. You produce good content and also information on what the sailing life is really like. Good luck and safe travels.
Thanks.
I am getting discouraged about our view numbers. Other channels with fewer subscribers get 5 times our views.
Maybe we should just film kittens and puppies.
@@Clarks-Adventure You've said it yourself, other channels do entertainment - you are creating a treasure trove of educational content. Your videos are targeted at those already living a sailing life or who are serious about doing so one day. This community will keep going back to your videos as a library of indispensable knowledge. Please don't get discouraged by the numbers - and know that you're creating 100 times more value than kittens and puppies. Keep up the good work!
@@Clarks-Adventure I've seen those other boating adventures where they literally hire young 19 year old models in string bikinis to dance around on the deck. Throwing champagne in the ocean...laughing drunk. lol, you two are too responsible, too crafty, too serious.....those other boating vessels are FAKE, yours shows reality. better to have a good solid normal subscriber base.
The quality of your viewer market can easily trump the quantity of eyeballs simply seeking entertainment. You said yourself that you weren’t interested in creating a business these days. They are. They have a sailing entertainment show business and must keep up the entertainment value with puppies, bikinis, exotic locations galore etc. It’s how they are making a living. Seemingly you already did all that business stuff and set it up so now you get to make only the videos you want to make without the pressure of feeding your “video monster”. …. Just saying.
@@Clarks-Adventure IF you want more views…
You just need to be more playful with the thumbs.
The thumbnail picture should be an overhead picture of you lying in bed uncomfortable.
The text on the thumb should be: Stop sleeping in your sweat.
That alone will double your clicks.
The video title needs to be expanded to "Battery-Powered Air Conditioning on a sailboat."
The content is great!
Don’t change a thing with that.
Just have more fun with your thumbnails.
Just found y'all. Exceptional channel. Should have a million subscribers.
Thanks, I'd love to have more subscribers. Please tell your friends and share video links.
Love the proof of concept! Thanks for posting this and the potential to acquire the goodies to make our own. I filled out the survey and I'd be open to all 3 choices... The DIY Kit may be the most versatile as I plan to apply it to my Class B Sprinter van RV for my land adventures. My pup/co-pilot will appreciate this when I have to leave him in the van on occasion. Boat comes soon... 2022!
I wish I had seen this before I retired from the transportation business. Now I live on a houseboat plugged into shore power.
I put a rooftop RV unit on the roof of my truck, since the OEM compressors were always going out. It worked great, but took a lot of power (2 alternators @ 270 amps each & a 5,000 watt RMS pure sine wave inverter).
I wanted to develop a no-idle battery bank system, but never found a system that would be practical (too many batteries; space & weight limitations.)
A low power system like this one that did the job would have been the answer.
I've thought about pumping water through a heat exchange unit with a fan on my houseboat to augment my two window units, since they struggle when it gets into the 90s.
Great videos, keep up the good work, Sir! 😊
The time slots I wish everyone did... saving precious time is essential! That's the first time I've seen a survey on a UA-cam video so that's pretty cool thank you for the time you shared with us. And looks like a really small unit! The amps and the Watts and it uses is incredible but you already knew that
Looks great Clark, the head of the opposition said if we buy a boat she wants AC, so gotta make it happen
When you get the boat she gets promoted to Admiral, you're the able bodied seaman.
"Head of the opposition." Never heard that one, love it. Will be using that.😂
I saw where a person ended up grafting a mini split onto their boat. They made a cabinet to cover the outside unit to make it look better but was still able to ventilate. Their draw was 850 watts to cool and it came with a soft start to make it run from an inverter.
I'm wondering how well it holds up to ocean water
@misham6547 it should be just fine. It's made from the same metals your refrigerator is except for the condenser which is titanium, which seems to be the best for salt water.
I've run the prototype for 5 years now.
Pleased to see that you were serious and still responding to comments.
Great-looking idea and I am buying an air conditioned boat tomorrow
I will see how the existing system works and if it is not up to speed I know it is marine ACDC and I will look up further on the internet now
Best wishes to you and lovely to see a great idea pursued so enthusiastically
Survey done- I love your videos on how to- and all the other ones too. Definitely interested and looks simple enough for the average Joe for the DIY part. Keep them coming and stay healthy both of you. Cheers from Montreal
Very nice of you both for sharing your knowledge and helping boaters
Man that’s amazing Clark. And I was a professional mechanic and ac was part of my expertise.
Clark, fantastic thinking and inventing! I love it! I have a 1973 Challenger 32 that I live on in Florida (St Pete). I have a really old Marine-Aire unit that was working 2 months ago, but has a leak. I'm planning my cruising for next year and looking at a new Dometic keel cooler unit (12-16k btu) but then I'm stuck on shore power or a generator or my inverter. I've got 200 watts solar now but could go as much as 800-1000. I'm also ready to pull the trigger on LiFePo batteries. I've filled out the survey, please keep me posted!
This is extremely cool and I hope your offering this when I'm finally able to buy my boat and hit the water. I'm about a year out from that yet finances willing and would definitely be interested in two or even three of these units for different spaces on my boat. As long as it isn't to crazy expensive that is. This would also help me when I can finally buy my dream in being able to pick a boat that may not already have AC on it and could save me a ton of money. So thank you for making this offering and like I said I hope it's around in a year or so when I know exactly what I need. Fair Winds and Safe Travels, God Bless...
Pun intended?
I am in a very similar situation. Think several smaller units would be better.
Congratulations on your thinking abilities.
Thanks.
They are available at marineDCAC.com
I am very interested in the concept and product, but it will be at least a year before I would want to install one. I will check back after I purchase a boat!
Keep up the good work on these awesome videos!
System looks great there and so efficient! I just wished I lived where I would need to use A/C more than 3 days a year :(
I'm currently building a cargo trailer to camper conversion, we decided to use a Pioneer Mini-Split. We will know in a couple weeks about the wattage numbers and efficiencies. Specs show about 330 watts on the lowest setting, and about 1300 watts on highest. If we can't dial it down low enough to run on solar, we will order one of your systems to add as a sustainable 24/7 system!
Great Videos!!!
I use a Pioneer mini split at my house. Good piece of gear.
I Love the concept, and I have to agree, that sleeping comfortably in the tropics, or subtropics is quite the challenge on a boat, or offgrid. I have filled out your survey to possibly adapt it to RV boondocking, or grid down scenario. I'm also looking to install on a small boat to camp in while in The Keys. Kudos for sharing your innovations...
That is awesome that you figured this all out. Good job buddy
Clark, this is fantastic. Thank you for the video and the effort in bringing these to life. Cheers.
Amazing you are the first to look at s all room AC on boats that I efficient enough to run on batt power sourcing parts and developing a working model makes you a genius cheers to you
I need this. I want it, it's 4:44am and I'm pouring sweat, my bed is destroyed, if I don't get one people in space will be able to smell me.
I've been in Florida for 21 years and I have not acclimated (acclamation is a myth). I don't know which kit I would use, but if it's a bucket of parts the bucket will need drainage or it will fill with sweat before I'm done putting it together.
Yes Florida is special. I've lived there as well. It gets cooler as you go south of key west.
The DIY will be available first. Fill out the survey in the description to stay in the loop.
Was born here, never acclimated in 40 years. Completely agree.
Born in florida sitting on an a/c vent.
Hi Clark, this is just amazing. We are moving back onto our boat in Greece having just had our first baby, and the only thing holding us back is the heat in the boat at night! We have a beautiful CT41 ketch but she retains the days heat so much, its like a sauna at night, so we completely agree with you on this as an issue! Now we have a newborn to look after as well so we are very very keen to get a hold of one of these! Sadly though, we will have to address our battery bank and solar first... Still in the dark ages with the Lead Acid bats...
Thanks Matt
The AC units are now available at MarineDCAC.com once you get your system up to scratch.
Do you know about my BankManagerPlus?
www.emilyandclarksadventure.com/bbms
It and a Lifepo4 battery or two and you are good to go. No need to change anything in your charging system.
Fantastic video. This is great. We sail in Norway so not essential equipment - but I want one simply because of your enthusiasm ;-).
This guy is a very smart cookie I love your work...mad scientist at the very best way
I´m really interested in this option (and has filled in the form), but I also contemplate an even simpler version where one can attach tubes to and from one or two sleeping bags and only cool and dehumidify the air inside the sleeping bags.
One month away from owning a 1972 Bristol 38 and I really enjoy your videos. As soon as Im a sailboat owner I'll be more than a subscriber. Im hoping for 800W of solar and 2x 18KW banks of 48v LIF04 batteries. Once I get that dialed in I am going to want to discuss AC & refrigeration with you. Keep up the great work.
Thanks Jay,
You are going to love the heavy boat. None of that flimsy modern plastic for us right?
If I had a sailboat I'd be in like Flynn. I've been cracking my head for a solution like this.
Clark you are the man! You might remember that you helped me rig up a mast head tri light with only two wires and a couple of diodes added to the light. Circa 2000 in Mexico. We used that light for years until LED's were available. I love this AC idea. We could have used it in Borneo/Malaysia/Thailand. Though we survived without AC at anchor. SV Green Ghost. Great to see you again!
Glad that helped.
Are you still cruising?
@@Clarks-Adventure We cruised from 2000-2004 Vancouver - Australia. Then relaunched in 2008 in Australia while I worked there for a couple of years. We left OZ for Indonesia/Thailand in 2010 and by 2017 we arrived back in Canada via South Africa. Back to work in 2017 but managed a three month break on Great Lakes this summer. Getting a new engine, paint job, another sail - etc. You know the drill. More cruising for sure. We've done about 40,000 miles. We need a break from cruising every 5 years to reset our brains and do something else. Anyone tuning in to your channel who reads this - BEST THING EVER! Go cruising.
Battery powered AC really wasn't practical until just the last few years, good job, enjoy!
I just found your channel through “Lady K Sailing” a few weeks ago & LOVE your stuff! I started watching them all from the beginning, Please keep up the GREAT CONTENT!! Gary…
I really like the full DIY option, and I would go so far as saying separating the parts so someone could purchase just what they need would be handy as well. For example: someone may want to buy a couple compressors and condensers, but use different evaporators. I am very interested in the compressor alone, because I have a different plan for using it.
Make sure you fill out the survey. That's how you will know when it's available.
Great video. I’m Offgrid and my 5000 btu Air conditioner uses about 38-40amps and I have enough solar to cover that it needs a lot of battery for the night so this would be a cool option for night time.
Hi Clark just subscribed you look like a great channel. Your AC vid is super interesting. I am thinking you should also connect to the #van life community as many are searching for something similar and like sail boats space and electrical consumption is at a premium. Most van people have insulated their vans so your unit would be really interesting. Most van self builders would probably do some of the assembly but not complicated wiring etc although some are brainiacs and could assemble a spacecraft in their garage hahaha
Thanks for subscribing. Feel free to mention us anywhere or send out links. We'd appreciate the new viewers.
I was here looking for ideas for a cooler for my dog for when he comes out in the van with me 😉
This is a pretty awesome project. If I ever figure out how to clear out enough room on my little sailboat I'll check back in.
REVIVE THE KIT - Are there people viewing here interested in having this 'kit' revived including a channel/user group? Respond to my comment.
Yes we do.
Yes!
Parts for the kit are coming from the manufacturers now. New products on the way
Check out MarineDCAC.com to get on a mailing list and as soon as parts come in it will become an order page.
Yes to your question what ever it is your saying lol
I hear one more week and the kits will be available again.
Clark, I want one! I have a land sail boat, some folks call it an RV. I can totally see this working with taking the edge off at night. It's a tiny one and an older one that has a massive following made by Toyota! So excited, this is awesome
Have you filled out the survey yet?
@@Clarks-Adventure I'm filling it out as we speak!
I’m interested in the pricing structure, please.
Fill out the survey and once I find sources for the components (not easy) I'll post a price somewhere.
Me too. I was almost done with the survey and att's cell signal just stopped, happens all of the time. I'll get back what I can n start all over.
Same ;) Filled out the Survey :)
I remember when that compressor came out about 11 years ago. I was blue back then, I can't recall the name of the company that sold it, but it was extremely expensive going for $1,200 just for the compressor alone. The capacity was incredible and was advertised as being able to run an AC and well as a refrigeration system at the same time. Also, setting it up to run was rumored to be beyond the ability of the average person. China came out with a black knock off which runs for about $200 which looks a lot like the model you have. The key I think is to have it pre-charged and on a skid ready to be connected to pre-charged lines like the Cool Blue refrigeration system.
Clark, first off I'm not trying to step on your turf. I'm "retired" too. What follows is a story of air conditioners on boats. I think it may be worth a read.
I'm in Texas and kept a roomy old 23 sailboat on a lake here. My wife and I loved spending the weekends out on the boat spending nights at anchor in a cove. On summer nights it became intolerable for her. One summer I took a sabbatical (semi-voluntary) from working and spent a lot of time on the docks. I'm a geek, lots of physics/chem schooling, and was pondering how to cool my boat w/o running a genset. One day I got a new slip-neighbor. Nice guy, we became friends (i.e., I recruited him as racing crew). Turns out he owns a small air conditioner company building specialized industrial AC units. Interesting...
I pestered him with questions about component availability and told him what I was considering. Did he know companies I could look to for components? The next weekend he showed up with a box of the parts I had asked about basically just a heater coil, blower, and a certain type of mechanical thermometer. I built what I later learned is called an ice bank air conditioner. I filled an insulated tub with lots of ice and pumped water over the ice with a tiny live well pump. The mechanical thermometer cycled the pump on and off to maintain a water temperature of about 50F flowing through the "heater" coil. The blower blew cool air into the V-berth. Using that small blower this would provide cooler and dehumidified air to make the 90F Texas nights tolerable for about 6 hours on 50 pounds of ice using one AGM battery that also ran the anchor light. This was the days before lithium.
Not high tech but it worked and I shared my math with my new friend. He responded with a job offer. I signed on and went to air conditioner school. 25 years later as a partner in the business we received an offer we could not refuse and sold the business, retired in my 50s. That offer was significantly inspired by the self contained lithium powered AC system I had designed.
Naturally there is a non-compete and IP I sold so there is much I cannot discuss. What I can say is that you are on the right track. What you really want to do is better manage your air flow so you can eliminate the fans. Using an efficient BLDC blower that runs whenever the system is on and only cycling the compressor as needed is more efficient. Sleeping in a boat you only need cool air to the face and upper extremities to be comfortable (enough). Think of where a car AC blows, face and hands. Cooling the walls and ceiling do not add comfort but you are totally correct that the air must be constantly moving. BLDC blowers aren't cheap but from China they are less than two $100+ fans and use less power.
There must also be _some_ source of fresh air. Humans exhale 20,000-ish PPM CO2 (top of my head number) and begin to show symptoms (drowsiness, discomfort) at about 1,500 PPM. you don't need much fresh air but in a sealed space you need some. If you turn your car onto "Recirc" is still pulls in that minimum. Remember it was CO2 abundance, not O2 deprivation, that almost killed the Apollo 13 astronauts
I have chartered cruising boats that used automotive style compressors belt driven from the engine to keep the fridge cold plates frozen with a few hours of engine time in the morning. If I were outfitting a cruising boat today I would seriously consider using a similar system to freeze water for cooling cabins later in the evening. Webasto in Europe markets a system like this for use in the sleeper compartments of big semitrucks after a long day of driving. Those components may well be appropriate for use on a yacht.
For me the fascination with ice bank air conditioning stems from the simplicity of rejecting heat when energy is abundant and absorbing heat when it is scarce, kind of like a battery but without so many inefficiencies. Yes, low temp refrigeration is less efficient that high temp AC but that is offset by use of a water cooled condenser. I might consider using a more efficient brazed plate heat exchanger for a condenser and a secondary coolant loop to put the heat into seawater, but that may be overthinking the issue.
Application specific observations: The block type TXV in your air handler is poorly calibrated for your compressor capacity (if it is calibrated at all, most are junk). United Refrigeration dealers can help you choose a better one.
The small compressor you are using contains little lubricant. If air conditioning a V-berth or other area further from the compressor consider using a _properly sized_ oil separator before the condenser to prevent oil starvation. Adding extra oil to the system must be done with real caution. There is more than fits here to that subject.
I will look into improving the expansion valve.
@@Clarks-Adventure With a good externally equalized high temp valve, 7-ish degrees superheat (Sporlan brand, right refrigerant and capacity) you may be able to run your compressor more slowly and are far less likely to have the compressor fail early.
military contractor makes compressors with inadequate oil system?
@@briansb2455 this unit is not the original milspec one. It is a Chinese reproduction at about 1/4 the price of the original. Still quite efficient, but not a $1200 compressor.
Definitely want a video showing installing and building
The intro music reminded me of The Red Green Show. If the ladies don’t find you handsome they’ll find you handy.
What a great channel...you guys are truly "givers"! Thanks!!!
You're very welcome
Clark I want one: plan 3, maybe 2... but alternatively, is it possible to make it portable (galley daytime, berth nighttime)?
You need to fill out the survey to be informed. We are building a webpage now.
I don't think you would want that as you would have to move the water lines. But to do that you would get the kit (which will be available first) and set it up any way you want.
Personally I'd just duct the air. There are 4 flanges on the air handler you can connect to duct work.
Clark I want one...box of parts/option 1...heading over to fill out survey now, then buying you a beer on Patreon. Thanks Sir...genious
Thanks, I can taste the beer already.
I like watching your channel because your the type of guy that figures stuff out!
He's Clark. He's knows stuff. Kryptonians...theyre like that...
Brilliant idea, filling out the survey now.

Can you share a link?
@@dereknolin5986 ,
Just got a new phone, still setting it up. Trying to find it the other night and couldn't. I found it the first time by asking on my phone, 12-volt air conditioning videos on UA-cam and it came up. Wish I could be more help.
@@dwightbernheimer331 Thanks, I'll try searching for it.
Hey, I do not know you or your channel but this popped up in my feed.
I am a maintenance tech at a factory and we have these super small air conditioners that cool down electronics cabinets.
These are bigger cabinets than you are imagining though, maybe 2 feet deep by 8 feet high by 12 feet wide, but I am sure there are larger cabinets out there.
People could probably size one to whatever size cabin they have if DIY is scary to them.
Using saltwater over air for heat exchange is smart though.
Living in Vermont... this strikes in my heart
Those small rotary compressors are compact, but the linear compressor while bulkier are even more efficient.
I was googling 'water medium mini-split a couple days ago, and all kinds of variations to see if anyone used water to pass cold from compressor to indoor unit and found nothing. Then youtube recommended this, and I see someone has done it! I was thinking antifreeze, but salt water can go below 0F, good enough for a/c, but not so much for a freezer.
Seattle's never hot !? we were there on our 4 corners tour, and it was 113* for three days on the record breaking heat wave ! Loved the area though! great vid! I' glad you found a way to keep cool!
Yes it's crazy out there now.
Great Job. I’m interested too! I’ve built regular units but I’m fascinated by the little compressor. I’ve put a lot of thought into solar a/c for my sailboat too. You did an awesome job of making it.
Thanks. Fill out the survey if you want to be in the loop.
Great air conditioner Clark, Hope it all works out for you, And if you would like to expand the demographics you could always talk to campers, Or even camper manufacturers they would probably be very interested
Absolutely Brilliant the thinking you have been doing and the mission you went to find what you thought was invented. I literally just saw a company come out with a 12 volt. Must me the same as you were thing. You have an awesome mind to create. I love hearing ideas they are exciting to grow on. 👍
So far I haven't seen any competition that is close in efficiency. Unless, of course, you found this company MarineDCAC.com
Thanks
Sign me up for any of the three options. I love the idea and the approach. Good inventing sir!

The Scirocco 2 fan is excellent had 6 of them installed since 2017 still going strong. Not expensive for that level of quality
Glad to have you sharing this “cool” (your words) idea. Very interested. Will have this over refrigerator.
BTW, We were just fine for winter in Bahamas without fridge. Rum not beer. Meat where available. Don’t drink milk. Ate last nights leftovers for lunch next day. Most things in fridge don’t need to be there. We never had butter, Mayo, pickles, eggs, open cat food, ketchup, real maple syrup, mustard, cabbage, carrots. Nothing wrong with many things from a can. Didn’t suffer, wife creative cook.
Well you are the first to prioritize that way.
You have to fill out the survey in the description. I have no way to contact you otherwise.
@@Clarks-Adventure I filled it out. Along with the AirCon I think I’d like to have a water maker, still before refrigerator. No one ever said I was normal.
Comfort over calories
We’d love one! Even in the summer it’s fairly cool in the evenings here on the west coast of Florida but we have plans to cruise further south so we will need something! We’d like the fully assembled and charged unit.
Yes… I filled out the survey!
You guys are so helpful…. I want a boat FIRST! Then I will get your kit!
Hey Clark, this is Remco from all over Europe.
I watched your videos again now that I have bought a catamaran.
It already has 2 ac for 2 cabins each.
What I like to know is if it’s possible to compressors on one system? Than I can cool high power with the generator for a our and than switch over to low power on battery.
Also like to talk about eddying Lithium to lead, ore making a new bank just for the ac.
Please let me know how to connect?
Thanks for your content!
I responded to you on Facebook messenger. Hope to see you on Patreon as a "Dream Believer" tier soon so we can talk on the phone.
So let me preface this with I have fallen in love with heat pumps. Now, my ten year plan involves selling my condo (once its rebuilt from the fire of course) and then buying a boat and moving aboard. Keep in mind I live in New England (Massachusetts actually). So heating my boat is a high priority for me. I am exploring all options on this front, including diesel heaters with radiator pipes leading through out the boat (including under cabinets and bunks and even the lockers) to prevent frozen pipes and the like. I understand you not caring a hill of beans about heat because you’ve given it up for tropical settings. But I just watched an interesting video on heat pumps and in it the video stated that central air systems have 95% the same components as their heat pump cousins. So then the whole process of how a heat pump worked and how it was the same process as air conditioning only there was a reverse feature added that could turn your evaporator into a condenser and vice versa. So naturally, that got me thinking about your system. Why? Because I have a curious mind I guess or because I do enjoy understanding how things work. So, my question is, since you are running your ac only at night, wouldn’t it be better to build a structure outside for your condenser to dump the heat energy your system creates? And how how difficult would it be to convert your system into a heat pump, so it could both heat and cool off batteries?
It does dump the heat outside the boat and there will be a reversing cycle version.
Also the air handler I use has a heater core inside it that you could run that hot water through.
This is very interesting, survey completed. I would definitely be interested in a unit, maybe two, so hopefully you will decide to bring something to market.
This looks great ! I am definitely signing up to get one, I hope you get enough people to put this into production !!
Clark I want one. I want a box o'parts. I am going on to look for the survey. Thank you for your work.
Thanks. It's all about the survey now. Link in the description.
What I'm gathering here, this is a great way to combine old and new systems as money allows. You didn't go detail deep in this but it seems to me that this should be marketed as a lithium only device as well. I'm not studied well on the big three's charging strategies but I don't think anyone is doing this.
I hope you've applied for a patent.
Yep I have a patent pending. Strangely the patent office takes UA-cam videos as proof of "prior art". So even this video protects me.
No this requires lead. Or at least another reliable bank if batteries. That bank can actually be tiny.
@@Clarks-Adventure when will the two be available to us and what is the estimated price point for the two?
It's still up in the air but I'm thinking $200 and $300. That might include the contactor, might not.
Supply chain is a mess right now. A chip that should cost a dollar is now $9.00 and it's big and better brother simply isn't available.
So once I get through the software I'll see what chips I can still find and start production on the new boards.
Announcement: I just sat down to answer these messages from all day in my lab. I have a bbms+ prototype that WORKED. Single first test but everything worked! Seemed a good time to kick back for the day.
You are the first to hear.

Just filled out your survey thanks for your time
This is more impressive than the window rattler in Floaty Boat! ⛵ ❄ 🆒
I just bought a boat with something very much like this installed. It doesn't appear to be stock as it looks brand new mounted on new lumber in a 35 year old boat. The ducting is run for the most part, and it seems to all be there. I'm lucky I have a friend that is an HVAC specialist and says he can get it going no problem, and parts are everywhere. Fingers crossed 🤞
Clark Great job. I do not have a boat but when I get one I will want one.
Watts are never "per hour" unless one literally means that the power consumption is increasing constantly over time. In ten hours, so by morning, you'd be drawing half a kilowatt. You probably meant it draws 50 watthours per hour (50 Wh/h), which is a 50 watt average power consumption due to drawing more (185 W) when it does run but having that 28% duty cycle once the temperature set point has been reached. That match checks out by the way: 185 W * 0.28 = 52 W so it's bang on. That's a good system you've got there! It's doing the most with the least invested in terms of money and consumed in energy over its service life, and you know exactly how it's put together! Major kudos.
Yes you are right I should have said 50 or 60 watt hours per hour average.
I think most sailors think in amps so the 14 is a more important number.
(Note NOT 50kWh/h).
We all make mistakes. :)
Thanks for appreciating my work. It still shocks me it works for so little power.
@@Clarks-Adventure Oops haha, yes. How did the k sneak up in there. Anyway, we are on the same page. Cheers!
:)
This is great. From what I've seen out there, a brilliant ground breaking innovation. I've been cramming to learn about solar. I use thermo dynamics to cool my house. I heat one room in winter to save money. My body prefers a warmer climate. I've lived around the world. Always need a way to cool off to survive though.
I might end up living in a box truck I'm working on, needs some help, 75 Dodge CB300, but in a boat in Florida or NC would be great. Might end up in a subterranean hovel in the desert. I'm somewhat disabled, rehabbing from a brutal life. I see a lot of people who could use this, just to make a cool place to survive. I'm very handy, but not too smart on AC systems or electrical. I test as genius, but I know I'm stupid in some areas, lol. Brilliant in others. If this is dependent on a massive source of water that would limit the possibilities, if not the applications could be huge, wide and deep. I know I'm going to need this. Don't know if I'm going to be able to afford it for some time. I have an idea what the battery and solar system will cost.
I think if your system creates dry air, a small evap system could cool as augmentation, but there goes the dry air, poof, lol.If it dries efficiently enough, using with seperate evaporative cooling might be synergistic (just need a fan and water flow, which is low volume and can be done by gravity by suspended tank) though usually that sort of synergy gets blocked by reality of physics, but sometimes it can be great. If your system would work in a desert with a small water tank, the combination would be almost a no brainer.
Thanks. Nice of you to say and astute of you to notice.
Yes it can work with air cooling. You need to spend more power on a fan and the compressor needs to work harder though.
No the swamp cooler doesn't help.
You should look at the chemical dehumidifier AC that "Tech Ingredients" showed in his video. I think you might really like to watch that.
Completed the survey. Great video!! Thanks Clark!!
Clark count me in. Complete system. Thanks
Good to know. Have you filled out the survey yet? That's the only way to be in the list
Also, should be available very soon. For kit form with fill system coming soon after.
Great stuff, would love to see a video of building and installing this
Great Job Build it Refine it and Build it even Better Helping and educating others with your Creation. Best of Luck Be well Be safe. Excellent Job
Great innovation. Maybe it's time to reno the cabin and get that that big queen bed! I'm sure you could do it. Cheers.
Well I could but I also like to be able to steer the boat. That's where the steering gear is located.
@@Clarks-Adventure maybe a conversion to fly-by-wire is in order? Lol
Jk... one more thing to break...
Newly subscribed. I love this video ! I'm not great with the back and forth from C to F (I'm 71), but you are fun, and i like engineer inventor energy!
Up to 5000 BTU's now? WOW! Can't wait!
Just found your channel. Excellent!
Clark, I want one. I'll be buying a boat this winter/spring, and yes.. I want one.
I'm saving this video, I'll email you after I start adding gadgetry.
What refrigerant is the compressor designed use? 410, 134a, 1234yf etc.? Thanks!
134a. I like to use what is easiest to find.
Very serious Clark. Filled out form under jack r
Very well done.
Just note that the wiring "mesh" may discourage some people.
Yep.
But they are free to install theirs any way they want.
Clark, Hey thanks for all of the great experience you share with us. I am a retiring controls engineer and the advice you give to the cruising public is just excellent. I bought the AC unit you talk about in this video and it will likely be installed in a few weeks. Looking forward to reaching out to you directly about it but don't have a patreon account set up. Can I just support you via Paypal?
Sure Ted.
By the way, I just installed the first air cooled version of this in a camper.
@@Clarks-Adventure hey Clark, I have a need for a small unit in my Dodge Van. Would yours work for that? And how much?
Tomorrow morning I'm releasing a special video just for you.
I'm serious stay tuned and subscribe!
Can you please provide the list of parts (Make & Model) needed for building this Battery-Powered Air-conditioning system.
Nope I can't. I sold the design to a manufacturing company. Besides the compressor isn't available to the general public.
If you fill out the survey you will be informed when kits are available.
Wow. That’s cool. Wonder if it would work with a travel trailer. Clark just talked with your dad here in Florida. Take care. Safe travels Clay
Hi Clay,
Sure I'm planning on offering a camper version. We are having trouble getting parts
Seen those compressors on Chines website 12V variable speed mini scroller. Nice to see one in use. I am quite impressed with the duty you got out of it. As an RV person my self. As a fridge engineer by trade that has an all round understanding of Solar batteries and inverters etc. After watching this video considered if using just cold sea water running through a finned heat exchanger in your cabin would be enough. But looks like in your part of the world the sea temperature reaches 26C So would not be very effective.The sea temperature in the UK is between 8C-17C and would work well. But inversely our climate is not as hot as the tropics.
It's actually a different compressor. Wish I could use the Chinese version as they are WAY cheaper. This one was developed under a DARPA contract. Although it looks the same. The Chinese claim a COP of 3 for their unit. Mine claims a COP of about 8. And since their only client just now (besides me) is the US military I believe their claims.
Have a 5KW Northern lights runs my AC units works great last a long time.I only use it at night to sleep well, makes everything better.
Nice Job Clark. Yes I want one. Have completed your survey.
Cheers from the Philippines 🇵🇭
Wish I had seen this video sooner! Hoping you were able to move forward with the AC, and that it’s still possible to get in on it.
All the parts are in. Should be soon.
Great! Please do keep me informed. I’m on the hard right now, so no better time to install one of these.
Great video never miss a episode
Clark, I want one and maybe two. Also the BBMS+ when you have them ready
Thanks Brad,
The guy I contracted the AC unit to says he will have a web page up soon. Fill out the survey and I'll notify you when he gets it done.
Had what seems like a final breakthrough today on the bbms+. We are happy with it's features and it seems to be working well on the test boat.
I'll be ordering the final (for sale) boards very soon. Hope I can find all the chips I need. Parts are getting scarce out there.
Looks great - I'd want one in a boat in the tropics for sure!
I want One. and I'd like to include it in my growing product lineup. I cater to people with small sailboats - typically under 30 feet who want some of the ease and pleasantries that larger boat owners enjoy - without the big boat expense. I'm also developing a plan to convert a SeaRay 270 into an electric propulsion trawler. I've been following SV Uma's success and am blown away at how far north they are operating. I'm intrigued with your low power consumption DC compressor as the last thing on my project list is to dump the ICE generator. I already have a working boat AirConditioning system installed but the system runs on 110AC supplied by the generator. PS - I live and work in Phoenix AZ.
Fill in the survey to be in the mailing list
Clark, I want one, precharged. Awesome system. Probably cool my whole (28' on deck) boat that was insulated for Northern climes.
Did you fill out the survey?
