@Sail Life, sorry for this being my first comment on one of your videos. But as an HVAC/R Tech I have to say you did a decent a job, however, you're going to see a minimum of a 5% efficiency loss do to insulating both the low pressure return line, and the high pressure feed line. Insulating the low pressure line does two things, it prevents condensation and more importantly decreasing the amount of heat the low pressure line absorbs, reducing the amount of work the compressor and evaporator have to do to remove the heat. Insulating the small high pressure line, decreases the amount of heat the system expels into the air, increasing the amount of work the compressor and evaporator have to do. Insulating them in the same jacket, just doubles in the inefficiency by creating a closed heat loop the will build up the longer the system runs reducing efficiency even further. But otherwise you did a good job.
Don't wrap both hoses into the same insulator, that way you are creating a "temperature short-circuit", with a lot of energy loss due to heat exchange outside the refrigerated box. Basically the cold fluid get heated before reaching the plate, and the heated fluid returning to the compressor get refrigerated again between the plate and the compressor.
Definitely do not wrap both hoses together! You have to separate them if you want to have an efficient system. Insulate the cold one for better efficiency and to avoid condensation. Do not insulate the hot one for better efficiency.
Refrigeration doesn't work like that. As a matter of fact the tube from the compressor & aircooled condensor to the holdingbox (the evaporater) is filled with WARM liquid. The return tube to the compressor is filled with COLD gas (not liquid!) If you wrap both hoses to the same insulator you even improve the efficiency of the system because the liquid before the expension valve is undercooled. Also you can use the eveporator more efficiently because you don't need to worry about remaining liquid in the returning tube to the compressor (a compressor is a gaspump, not a liquid pump!) But to do this you need to make adjustsments to the thermostatic expension valve on the evaporator. Down-side of this is that the compressor uses the cold return gas to cool itself, and because you mount it under the floorboards I would follow instructions and don't insulate them together. Note here: the insulation on the return tube (suction tube) only is there to prevent condensation; it has nothing to do with energy loss.
Insulating both pipes together seems like mistake to me, in fact, isolating them from each other is your ultimate goal. It is basically heat pump, temperature difference in lines defines the efficiency.
A few points.: 1. Follow the installation instructions regarding wrapping forward and return lines together. From my recollection, sometimes the liquid line in refrigerators is actually located inside the gas return, so some designs obviously expect close thermal coupling between the lines. Bottom line is, the amount of thermal coupling is one of the design parameters and should be addressed in the instructions. 2. Vibrations in those copper lines might induce wear at contact points. Insulating the lines together may be fine but they perhaps should only be in contact where they are strapped together, not where they might randomly rub each other. 3. The evaporator in the bilge may be cooled by the water outside the hull but you may want to duct the warm air from the fan so that it physically passes along the hull. This will ensure the air gets cooled. Thanks for your presentation. I do enjoy watching someone else work!
Great work Mads, Short comment: don't insulate the high pressure line, and try to thermally separate the two lines. Long comment: the refrigerant coming from the compressor will be hotter than room temperature. The more heat it sheds on the way into the freezer, the faster and more efficiently it will cool your box. If it sheds its heat into the return line, the compressor won't be able to cool it down as far. Also, the efficiency of the compressor is highly dependent on how much cool air blows over the radiator. I think that location may get hot when the compressor is running. Might want to check out the compartment temp when the unit has been running for a while. Happy holidays!
Anecdotal support; a boat I crewed on recently had a cool blue system, compressor mounted under the galley sink. It had a seagull water filter for drinking water. We had warm drinking water. The owner has since increased airflow to the cabinet.
I have the cool blue on my boat, great system. And yes you will want to add more ventilation than that, might be fine in the winter but when you get down where the water is warmer, it will really hinder it. In the summer if I have been doing a lot of motoring and it is a hot day mine has to work pretty hard to keep up, so I pull the engine cover and that makes a huge difference. It is however a great system, mine quit on me and Rich called me on a sat phone from Mexico on a Sunday and helped me get it working within an hour of me sending the email! Met him at the Seattle boat show, great guy!
How would you know that they would want to add more ventilation for a warmer climate? You've only been sailing for two + years, and have never had your boat out of the northern waters of Puget Sound.
A suggestion. Mount a small computer fan to act as an "exhaust" for the compressor box. Air-cooled is great but requires air flow. In several restaurants I worked for, we mounted the air cooling outside the restaurant to improve the unit's efficiency. Just a thought. The downside is that the exhausted warm air will flow into the galley area. Merry Christmas, Happy New Year.
If you look at the back of any domestic fridge inside the pipe foam you will see that the capillary line is soldered the full length of the suction line. The purpose for this is for heat exchange .If you look at a Psycrometric chart you can see that it is a boost in efficeincey . On TX valve systems like yours they sometimes install a heat exchanger to the system. Just taping your liquid line to your suction line and wrapping them together with foam is sufficient . Cheers
For future reference Mads, if you have occasion to work with finer copper tubing again an exotic alloy known as 'Woods Metal' exists which melts in boiling water. If you pour Woods Metal into pre-warmed fine copper tube and let it solidify you can then bend the tube with little risk of it kinking or even deforming. After that, simply heat the tube in boiling water, pour the Woods Metal out again and flush the interior of your copper tube with more boiling water, be aware however that Woods Metal is toxic to touch! In the interest of wellbeing for you and your shipmates I suggest that you ensure any Sikaflex or other chemical compounds you use in the interior of your fridge are food grade!
Besides the insulation issue, it would be good to install an air ventilation vent to the compartment holding the compressor. The lower the temperature of the air reaching the heat exchanger, the higher the efficiency. Love the size of that fridge.
Yes there is a downside to wrapping those pipes together..... heat transfers from one to the other...... one pipe carries the fluid with heat, one pipe carries the fluid heat has been removed from.... when you put them right next to each other you made a heat exchanger that will reduce a lot of cost saving you went on about
Personally I would have put the cold plate inbetween the outer plywood case and resin liner that you made. That way You have maximum space in your fridge and you wouldnt have to wory about groceries banging into the plate or the thermostat in a big sea. The boat on the other hand is starting to come together and Athena looks great. .... ⛵💕🌠
What you should have gotten was a copper tube bender used by HVAC service techs and plumbers. They are fairly inexpensive and easy to use, and you can make some tighter bends without kinking. Note for the future?
That loop.is actually a good thing as it will act like a trap and help create pressure to force the oil back to the compressor from the plate.. So its a good thing, not needed on the smaller tube.. Hopefully you have a small vacuum pump, it will be a good keeper should you need it in the future..
As ever Mads you are making superb progress. I think the installation of ‘cool blue ‘ has garnered the channels record for specific comments - so I am not jumping in as well.😂 Hope you found some time to enjoy Christmas and the world can get back to some sort of normality by the time you want to go cruising with Ava, although I am pessimistic for international travel opening up in that time frame. Best wishes.😀🎄👍⛵️
Hi Mads, great video as always! While watching the video I.had the same thought as some people below (as Jason has already explained it very well, I will not repeat the full technical reason) regarding the insulation of the feed and return line of your new fridge design. I am an engineer, and in my job I sometimes need to dimension and design heat-exchangers. This is obviously a mistake that can happen to someone not familiar with the, admittedly, sometimes rather complicated and tricky desing of such systems. AND this shall not take away anything of the otherwise fantastic and well thought through approach you take on rebuilding your boat and building your dream. I salute you on this, because I recognise that this is more than a marathon, this is an ultra-marathon at its finest. It takes a special person to maintain the positive spirit and the quality of work throughout these years (and yes, I am following you each sunday for the last "i dont know how many years"). I will end this by also wishing you relaxing holidays and a happy new year. 2021 will become very exiting on your channel!!!!
Excellent work, as always, and great to see progress coalescing on a finish :-))) Just a thought re the assumed absence of water in the bilge beneath the compressor - water usually gets in here from sources such as wet weather gear, (sails of course on a race boat), spillages, overflow taps, hatches left open etc and that bad day when water comes down the companionway, directly, so it may be worthwhile at least coating the elecs to prevent/limit water ingress or possibly a custom enclosure - sounds tricky, but you always do tricky so well. Cheers and good wishes for 2021!!!
You're right, as the gas flows through the coil, it does vibrate, which will eventually wear down the tubes. Something else you will want to think about is electrolysis. I'd place something flexible between the coil and cold plate to prevent them from rubbing in the future too. Merry Christmas
"Firmly planted in overkill territory" is where you started Mads. You are now approaching ultimate strength territory. Thank you so much Mads for a year of wonderful projects, glorious sanding and truly spiffy videos. Take care and wishing you and Ava a very joyous and productive New Year.
Mads can see the light at end of the tunnel. Darn, its just someone with a flashlight. Best you keep your nose to the grind stone. As always, nice work. 👍
Thanks for all of your efforts to entertain us this year, Mads. It's been weirdly healing to see you getting on, while my own project has been mostly stalled through unkind circumstance. Here's to getting stuff done in 2021. Cheers!!
The moist in the fridge might shorten the life if the thermostat.. If you want both freezer and fridge you can have a simple wall in the box In my boat i just have some aluminum covered bubble wrap The temperature of the fridge side depends on how well the wall fits, it’s nothing critical you just put the stuff that might get frost damage away from the wall..
Hey Mads, the unvented heat build up in the bilge compartment will shorten the life of the circuit board. You may want to vent it sooner than later. Love your channel and really respect your accomplishments on the the boat.
Mads, my boyfriend and I watch your videos every week when they come out. So I have to ask, we haven't seen Jökull in a little while. Is his cute fluffy butt okay? This is important to know!
Mads. You're nearing your end of refitting Athena. Have you given thought as to how you're going to approach doing videos once you and Ava start sailing... IF you do videos? You have a real talent for instruction. Will you maybe take that and apply it to teaching how to sail?
Merry Christmas Mads, and Eva. 🎄 Amazing how you keep your efforts to the “grindstone”, you demonstrate a disciplined work ethic. Bravo, I like to add I’m 71, and still learning, especially from young lads like you. Thank You sir.
Honestly, I could watch you all day! Personally really enjoyed the long vid last week, any chance on another 30 min vid? it'll help with the week long wait lol keep up the great work! Love it! and MERRY CHRISTMAS :)
Thank you so much! :) The average view time for my videos is around 13 minutes. I don't think most people want videos that long :) Once I don't have my pesky day job anymore I might be able to do two videos some weeks :)
@@SailLife MADS! You are 100% incorrect. We all want 30min videos from YOU. You're like that soothing and calming DIY guy that lulls our souls into believing we can make something successfully. 30 min a week would save lives around the globe and could possibly cure hunger and solve the issues in the middle east. It's worth a try! THINK ABOUT THE CHILDREN MADS! THE CHILDREN!!!
I have another Idea since you put the condensing unit into the bilge , it might be wise to put a spare bilge pump with a large capacity next to it just for some piece of mind. That's a beautiful condensing unit . If you didn't get instructions on how to read that sight glass in the top of the receiver , send me a reply. Excellent job as usual. Cheers
Mads, the tubes not touching each other.👍 I would start on the vents for the condenser now. If you look online you will find the relevant calculations. Awesome job👍👍👍 Happy New Year, to all. Best wishes,stay safe
I thought the same thing, need to separate the excess coils at least. The idea of refrigeration is you separate the heat gradient, the big coil of excess is putting the heat back into the cold side of the tubes.
Merry Christmas Mads. I can’t believe how fast Eva is set to arrive. You are so calm about all the work that needs to be accomplished between now and then.
Mads, that holding plate is an old Crosby holding plate... big plate and exactly the same as the ones we have converted on our passport 40. We did the same technautics setup 4 years ago. Works great except we did dual setup frig/freezer. Excellent choice
Not sure if I have said that before but I really enjoy the cool calm and collected way these videos document the refit of your boat. Also, there is a significant learning effect for me, maybe not the details because they are different in any other boat, but the some of the basic principals how things working on a boat. I am very curious how all of this will be once the boat is finished an ready to go. Merry Christmas and good luck in the new year with your refit. Christoph
I loved the "lists" you compiled before smashing Athena. They were stickies on the wall (LOL). It really helped me see and understand your process. Can you continue this?
So smart to go with a satin finish! I'd suggest rubbing with #0000 steel wool with furniture wax as a lubricant after it cures for a few weeks, it will look fantastic.👍
Nice compressor unit, but sorry to say that you will either have to move it to a vented cupboard or add fans that has free air intake and outlet. I have mine in a big cupboard (150l) with five 40mm holes at the floor and five 60cm further up, it still gets hot in there. I think that unit produces around 250-300w heat and you actually waste all your nice insulation by lowering the efficiency of the compressor.
Seasons Greetings Mads. That seemed like a nice easy setup. The fridge on my C&C 33 quit last season. This looks like a nice replacement I will have to look into. Great work as always. Looking great.
I installed the Large “O” icebox conversion refrigerator on my 35 foot Jeanneau eight years ago. No cold plate taking up space in the fridge. Cost around $700 on sale at Defender. Comes complete and ready to install. The BD50 Danfoss variable speed air-cooled compressor is quiet and efficient. Super dependable.
@@navyguywandell OK! First off, the complete CoolBlue unit has been charged with refrigerant and sealed by both Schrader valve fittings. It can be ordered with various lengths of tubing, in this case shipped with the standard 12' lengths. The tubings are both sealed and pre-charged at the factory with Schrader (male) valve. There is no need to evacuate the system with nitrogen and hook up fancy stuff to make it work etc. Hence the benefit of the system, it's a do it yourself installation. Do you remember Mads mentioning a hiss sound when connecting the line to the system. That was the sound of released pressure in the system. NOW! What do you think would happen if you cut the lines, fill them with sand, bend and braised the fittings back on? Answer: moisture, oil dispersement, freezing and eventual damage to the compressor. Your suggestion is valid in other applications but not with this system. Check this out: ua-cam.com/video/1525Hlg380Y/v-deo.html
I never said cut anything. I said fill it with sand, and bend it... he fills it with sand. Bends it, then empties the sand out and he has a bent copper tube thats not kinked. So slow your roll dude. No need to freak out.
Magic smoke to replace that lost from electrical wiring harnesses can be bought in aerosol cans. However getting the right levels can be tricky and unless an expert, is best done by an authorised Magic Smoke replacement franchisee.
Thank you Mads for another great episode - your work is inspiring!! If noise ever becomes an issue, it could be a fun project to program a timer into the fridge compressor so that it only/mainly runs at night. Best wishes!
Merry Christmas Mads. Three months left on the 9 to 5 job, other three for Ava to move over... I'm pretty glad watching your plans coming slowly but surely to life! Ceep up the awesome work. Happy holidays...
Merry Christmas Mads! Great video again, just little confused about the size of the evaporator you’ve chosen. It takes almost 1/5 of the space... What I am trying to say is that this evaporator is great and efficient but I don’t think is the right solution for your setup. Probably is not a bad idea to turn it to freezer or make the opening in two parts. Cruising life in the heat or long passage means huge need of refrigeration and most of the people I know have at least on freezer and two coolers on board. I guess you would say that this is stupid idea at the moment but ones you start cruising and fill the boat with food you will realise this is not enough. Just for example crossing the Atlantic DK to Antigua 38~ 50 days > 2 people > 3 meals a day x 250gr = 57kg ~ 75kg food. Approximately 1/2 or 1/3 of the food need a cooler. I hope that you will find this information useful! Lycka till och gott nytt år!
Assen I don’t think you understand a holding plate system. What you refer to as an evaporator is not that at all, think of it as a block of high tek ice. It needs to have sufficient mass to stay frozen for an extended time and to cool the interior of the frig during that period. This is a trade off for the reduced energy consumption of this type of system. I have the same system on my boat and it reduced my refrigeration energy usage in HALF from the previous evaporator system. Please check out the Technautics site for further explanation of this process. Ben
I fairly regularly experience 40c +. I got married in 48c.It was all very wrong. Mistakes were made. However such ridiculous temperatures are short lived It looks like a win to me. It'll be fine. Cold beer without just leaving it outside is important in hot places.
Merry Christmas and happiest of holidays to you, Mads! You are a constant inspiration and reminder that anything is possible when you follow your dreams. Thank you! 🎄💫❤️

I am not a tech but that what I was thinking👍👍
I agree, having worked with HVAC, I cringed when he wrapped both together.. it will work, but the compressor may come on more then it needs too..
Hope he sees this.
@@cnc75adventures49 My thoughts also!
Don't wrap both hoses into the same insulator, that way you are creating a "temperature short-circuit", with a lot of energy loss due to heat exchange outside the refrigerated box. Basically the cold fluid get heated before reaching the plate, and the heated fluid returning to the compressor get refrigerated again between the plate and the compressor.

What he said
You want the cold to stay cold and the hot to lose heat (by heating your boat) that way the compressor works less.
Definitely do not wrap both hoses together!
You have to separate them if you want to have an efficient system. Insulate the cold one for better efficiency and to avoid condensation. Do not insulate the hot one for better efficiency.

Watch this show EVERY sunday! Don’t own a boat and won’t own one in many many years but I find everything Mads does entertaining.
Ahhh! Seeing the sanding at the end was like
taking your boots off after a long day of hiking.
Now I can relax. Journey complete.
We always giggle at "[...] a somewhat extensive refit [...]". Thank you for your videos and documentary!

Athena is shaping up very nicely!
Thank you for that (albeit short) bit of 'Oh Glorious Sanding', I can now get on with the rest of the week. :)

Honestly, I could watch you all day! Personally really enjoyed the long vid last week, any chance on another 30 min vid? it'll help with the week long wait lol keep up the great work! Love it! and MERRY CHRISTMAS :)
Thank you so much! :) The average view time for my videos is around 13 minutes. I don't think most people want videos that long :) Once I don't have my pesky day job anymore I might be able to do two videos some weeks :)
@@SailLife can't wait! :)
How does viewtime work? Does it hurt the stats if I watch in two parts?
But I also love your longer videos. 10 min Mads and then 10 min pluralsite
@@SailLife MADS! You are 100% incorrect. We all want 30min videos from YOU. You're like that soothing and calming DIY guy that lulls our souls into believing we can make something successfully. 30 min a week would save lives around the globe and could possibly cure hunger and solve the issues in the middle east. It's worth a try! THINK ABOUT THE CHILDREN MADS! THE CHILDREN!!!
@@SailLife I don't mind
I have another Idea since you put the condensing unit into the bilge , it might be wise to put a spare bilge pump with a large capacity next to it just for some piece of mind. That's a beautiful condensing unit . If you didn't get instructions on how to read that sight glass in the top of the receiver , send me a reply. Excellent job as usual. Cheers
It isn't Christmas without some glorious sanding 😂Merry Christmas Mads 😊👍
I see a major problem with your new fridge, where are the beers getting nice and frosty! Merry Christmas and a happy new year of sailing.
Mads, the tubes not touching each other.👍 I would start on the vents for the condenser now. If you look online you will find the relevant calculations.
Awesome job👍👍👍
Happy New Year, to all. Best wishes,stay safe
I thought the same thing, need to separate the excess coils at least. The idea of refrigeration is you separate the heat gradient, the big coil of excess is putting the heat back into the cold side of the tubes.
Thank goodness for the Oh Glorious Sanding!! I thought we were going to miss it. Merry Belated Christmas and a Happy New Year!
Great job, step by step the closer you get. Can’t wait til the distribution panel and electronics are in..
Merry Christmas Mads. I can’t believe how fast Eva is set to arrive. You are so calm about all the work that needs to be accomplished between now and then.
Mads, that holding plate is an old Crosby holding plate... big plate and exactly the same as the ones we have converted on our passport 40. We did the same technautics setup 4 years ago. Works great except we did dual setup frig/freezer. Excellent choice
Merry Christmas Mads and Ava. Wishing you all very best. Happy sanding.
I have been waiting for several years for the upcoming videos 😄 Gadgets time ❤️ Happy new year 😘
Not sure if I have said that before but I really enjoy the cool calm and collected way these videos document the refit of your boat. Also, there is a significant learning effect for me, maybe not the details because they are different in any other boat, but the some of the basic principals how things working on a boat. I am very curious how all of this will be once the boat is finished an ready to go. Merry Christmas and good luck in the new year with your refit. Christoph
I loved the "lists" you compiled before smashing Athena. They were stickies on the wall (LOL). It really helped me see and understand your process. Can you continue this?
Nice! But holy hell that is expensive!!! Love your videos!!! Keep it up. I really cant wait to see whats next!
Making sure Tubes don't touch each other ABSOLUTELY matters.
Good call
So smart to go with a satin finish! I'd suggest rubbing with #0000 steel wool with furniture wax as a lubricant after it cures for a few weeks, it will look fantastic.👍
You should use bronze wool on board, but otherwise you are correct.
should add a temperature gauge inside the box with a display mounted outside. I use a digital one that is inexpensive.
Hiya, Happy New Year to you both... Stay safe...Steve...
Merry Xmas & a great New Year to you and Ava
Merry Christmas my friend hope to see you next week and hope to see your four legged friend also. 👍🏼👍🏼👍🏼
Merry Christmas 🎄 ⛄ ;)
Nice compressor unit, but sorry to say that you will either have to move it to a vented cupboard or add fans that has free air intake and outlet.
I have mine in a big cupboard (150l) with five 40mm holes at the floor and five 60cm further up, it still gets hot in there. I think that unit produces around 250-300w heat and you actually waste all your nice insulation by lowering the efficiency of the compressor.
What does the manufacturer say? Does seem strange mounting it in a small enclosed area. Vs the ones that use cold water that the boat sits in.
@@crankshaft007 The water cooled units are much more problematic, not in the same league reliability wise as a Technautics system.
It's allways good if it makes some noice, then you know if it's suddenly is missing.
Merry Christmas good sir.
Good job looks great man
Thank you for taking time to have all of us along! All my best for 2021
Seasons Greetings Mads. That seemed like a nice easy setup. The fridge on my C&C 33 quit last season. This looks like a nice replacement I will have to look into. Great work as always. Looking great.
I installed the Large “O” icebox conversion refrigerator on my 35 foot Jeanneau eight years ago. No cold plate taking up space in the fridge. Cost around $700 on sale at Defender. Comes complete and ready to install. The BD50 Danfoss variable speed air-cooled compressor is quiet and efficient. Super dependable.
Merry Christmas Mads.
hi the boat is looking very good
Congratulations Theo on getting the fridge up and running. Fantastic little unit. Happy new year to you. Australia
Best wishes from a 🇨🇦 fan.
Good job. Next time you have to bend copper tube, fill the tube with sand. It will allow you to bend it without having to worry about it kinking
Read comments before posting
@@nspctor7729 im failing to see someone else post this. I see where someone suggested using an HVAC tub bender however not using sand
@@navyguywandell
OK!
First off, the complete CoolBlue unit has been charged with refrigerant and sealed by both Schrader valve fittings. It can be ordered with various lengths of tubing, in this case shipped with the standard 12' lengths.
The tubings are both sealed and pre-charged at the factory with Schrader (male) valve.
There is no need to evacuate the system with nitrogen and hook up fancy stuff to make it work etc. Hence the benefit of the system, it's a do it yourself installation.
Do you remember Mads mentioning a hiss sound when connecting the line to the system. That was the sound of released pressure in the system.
NOW! What do you think would happen if you cut the lines, fill them with sand, bend and braised the fittings back on?
Answer: moisture, oil dispersement, freezing and eventual damage to the compressor.
Your suggestion is valid in other applications but not with this system.

I never said cut anything. I said fill it with sand, and bend it... he fills it with sand. Bends it, then empties the sand out and he has a bent copper tube thats not kinked. So slow your roll dude. No need to freak out.
@@navyguywandell
How are you getting the sand in the tube when both ends are sealed?
Magic smoke to replace that lost from electrical wiring harnesses can be bought in aerosol cans. However getting the right levels can be tricky and unless an expert, is best done by an authorised Magic Smoke replacement franchisee.
Ending this year with some glorious sanding!Happy and healthy New Year to you
Love the fuzzy dice!
Nice job!!!
Thank you Mads for another great episode - your work is inspiring!!
If noise ever becomes an issue, it could be a fun project to program a timer into the fridge compressor so that it only/mainly runs at night. Best wishes!
Oh glorious Christmas sanding and firmly planted in overkillwill
Glædelig jul Mads og godt nytår.
Merry Christmas Mads.......... Very Very impressed with your project to re-fit Athena.
Merry Christmas to you & Ava Mads.
You've done a really a great job on the fridge.
Merry Christmas its been wonderful watching you over the years 👍👍👍👏👏👏👏👏👏👏👏👏👏👏👏👏🤗
Merry Christmas Mads.
Three months left on the 9 to 5 job, other three for Ava to move over...
I'm pretty glad watching your plans coming slowly but surely to life!
Ceep up the awesome work.
Happy holidays...
Happy New year!
Merry Christmas Mads! I'm sure you are very excited to have cold beer aboard the boat :)
Merry Christmas Mads!
Great video again, just little confused about the size of the evaporator you’ve chosen. It takes almost 1/5 of the space... What I am trying to say is that this evaporator is great and efficient but I don’t think is the right solution for your setup. Probably is not a bad idea to turn it to freezer or make the opening in two parts. Cruising life in the heat or long passage means huge need of refrigeration and most of the people I know have at least on freezer and two coolers on board. I guess you would say that this is stupid idea at the moment but ones you start cruising and fill the boat with food you will realise this is not enough. Just for example crossing the Atlantic DK to Antigua 38~ 50 days > 2 people > 3 meals a day x 250gr = 57kg ~ 75kg food. Approximately 1/2 or 1/3 of the food need a cooler. I hope that you will find this information useful!
Lycka till och gott nytt år!
Assen I don’t think you understand a holding plate system. What you refer to as an evaporator is not that at all, think of it as a block of high tek ice. It needs to have sufficient mass to stay frozen for an extended time and to cool the interior of the frig during that period. This is a trade off for the reduced energy consumption of this type of system. I have the same system on my boat and it reduced my refrigeration energy usage in HALF from the previous evaporator system. Please check out the Technautics site for further explanation of this process. Ben
Lovely
Really interesting. Thanks for sharing with us once again 😀🙏
I fairly regularly experience 40c +. I got married in 48c.It was all very wrong. Mistakes were made. However such ridiculous temperatures are short lived It looks like a win to me. It'll be fine. Cold beer without just leaving it outside is important in hot places.
Why is 48c.It a link? WTF youtube. Even my limited Perl regex would have F'ed that off. It's a capital letter with a missed space.
Merry Christmas and happiest of holidays to you, Mads! You are a constant inspiration and reminder that anything is possible when you follow your dreams. Thank you! 🎄💫❤️
