@@bobomob111 lol, you obviously know NOTHING. Sir, do some research. Vibranium is far superior to marine brass, as is adamantium. You could also use unobtanium in a pinch. Dargontine also works. Sharks also last about 70 years and they don't get rusty, so could just use sharks. You could also use a non-corrosive, cost effective material known as platinum.

@@spacecadet0 Almost, but not quite. Swamp coolers trade humidity for temperature. For them to get rid of the heat energy, they change the state of water from liquid to vapour. That means you get cool air, but humid conditions. This system "gets rid" of the humidity as well as the heat.

I am also glad to see the ease of creation so most anyone wanting to can create themselves and thus saving money on installation and utility bills can do so!!! Awesome!!! The systems as used today are very inefficient when other alternatives exist even using systems similar to current build but again are refused usage for similar reasons as to why we are almost stuck using fossil fuels....money and power!!!

I live in a humid environment and have long since wondered what could be done to a "swamp cooler" to make it work in my area. Now I know. Great video, brilliant science, thanks for sharing.
If it's modestly humid this could work pretty good but the dehumidifing will be less effective as the humidity increases, I think the system will start to fight itself in more oppressive humidity
I have the same concept of air-conditioning using latent heat of evaporation and I am happy to know somebody is also experimenting on it. I thought of that dessicant to dry the air but it will make the system complex it adds heat to the system that you will reject again later, lowering the system efficiency. Just make a cascade system. Separate the cooling medium and the air to be cooled so there is no need for dessicant. Natural dehumidification will occur just need to reach the dew point temperature. You can further improve its efficiency by removing the blower for the swamp cooler and put thermal stack (solar) on top of the swamp cooler discharge to draw air from the cooler (can be combined with blower when there is no sunlight). This system really works. Making the equipment smaller is the challenge.
"...with tropical hardwood inserts in the fractionating column made from reasonably priced, yet commonly available tropical plywood. This gives it pleasing acoustic properties so it can double as an efficient horn speaker"
@Tech Ingredients i'm an ventilation engineer and i really like your basic idea of that air conditioner. But i have to mention two things. First of all you can't calculate the watts of cooling by measuring the two different temperatures. You also have to measure the humidity of the inlet end outlet. You must calculate the coolingpower by the difference of enthalpy. The second thing is, that you have liquids (warm liquids) in a circulation, that are in contact with your airflow. That could result in a hygiene problem. Keep on going with your really cool ideas :)
The entire system would need to be completely sterile, yeah. All I could think the entire time was "Could you imagine trying to clean that thing?" Sponges evaporating on warm grey water, eugh... Cool concepts, neat idea, but I can't imagine how it would work for longer than a demonstration.
@@youthised58 I'm sorry but i'm not able to say if that build is more or less efficient, because i don't have the measurements. In the part where he calculates the COP i also miss the integration of the heat from the burners. This energy isn't free. To your last question: yes i think its worth continuing. The idea is great, but he should get some help with good scientific knowledge to get it accurate.
I thought that with the CFM (cubic feet per minute) and Delta T (sensible thermal difference) you can at least calculate the sensible BTU's of this. Once you have the BTU's you can covert them into watts by dividing it by 3.412. this is just the sensible heat in the system not the total. Also could the hygiene problem be fixed by adding some sort of cleaning agent to the water flow( without it affecting phase change properties) I don't know enough to determine if this applies to this system or is accurate. I would love to know more if you could shed some light on the matter.
For your second reasonable doubt, that there could be hygiene problems with warm liquids in contact with the airflow, I think I have the following solution (though it is a thought experiment): One could use a heat exchanger. This would preserve all the non-hygienic parts from the airflow itself and you had to clean only the condenser occasionally.
I have been in the HV/AC feild since the 80's...and I found that if you sprayed a mist onto the condenser coil way back in the early 90's, that you could reduce the energy being used on that unit...and I then built a loop to surround my condenser coil..and attached my condensate drain line ( pump ) to the loop to spray water onto the condenser coils when the condensate pump need to empty, and this was short burst of savings...but it did reduce the amount of energy that was needed to power the ac. Now after watching this video, I think that you have helped me with a hump that I couldn't get over to save a lot more money on my electric bill. ( I'm not the most literate guy...but I do understand the principles of how it works..so please give me ) but I'll let you know the results of the out come..boom, thank you for this.
Anyone aspiring to build or experiment with non-closed loop air conditioning systems in residential areas need to be aware of the dangers of microbial growth including legionnaires' disease which can be fatal.
Don't forget mold. Where I live, anything that stays damp for longer than a few days gets mold. The mold spores outside are incredible. No matter what I do, they still get into the house.
I wouldn't want my home smelling like a swimming pool as the chlorine evaporates into the air-doubt that's particularly healthy to breathe constantly either. Could add a submersible UV sterilization lamp to the final output tube to kill off any microbes before they exit. Would add to the power consumption, of course, and who knows how much heat it might put off. I doubt much would grow in the desiccant side, though, with such a high salt content.
Bro! Hold my beer! I live in New Mexico we use evaporative coolers to great success by drawing hot dry air over water soaked pads, Temp drop of over 30 degrees! Works great! Only thing is it adds humidity to the cooled air. But when your humidity is 14% you don't notice it. And you use a lot less electricity!
Sometimes I wonder about putting an evaporative cooler in the vicinity of my external compressor, to lower the ambient air it has to work with when it gets >100 or 105 degrees (California, dry heat). We can't get the house below 78 in these conditions. I can't find anything on this approach online, so maybe it is less effective than running the evaporative cooler indoors directly. I have tried misting and it does drop the temp a couple degrees, but can't be good for the health of the coils.
@@polylight a small sprinkler system spraying the condenser would work better, liquids have better heat transfer/absorption than gas. Very light water spray onto the condenser would really help on hot days, wasteful on days where it's not necessary but a very simple fix for days when you absolutely do need it. Let the condenser evaporate the water you'd use in the cooler.
@@daniellawson5127 I've tried this and measured air temp drops with an infrared gun and it totally works! Can't remember the numbers but the drop was over 10 degrees in the ducts. I just worry about gunking up the coils with calcium and whatever else is in the city water.

Nah, you can't meter it and suck money out of the masses with this system. The initial costs is also too low, we can't justify a high price for it either by claiming the material or the complex (actually simple) design or development costs. Another competitor would out compete us. Just maybe if we can get the patent first that is, might as well put in a safe to be never released so we can keep selling our huge stock of inefficient, metered cooling systems perpetually, which need to be changed and maintenanced from time to time, cashing in one more time from these suckers.

What an amazing demonstration. I'd love to see this played in some sort of animation video, showing flow of air; colored temperature changing; rise and fall of watts used in the process (etc.) - then the COP laid out (and actual power consumption).

Thank you. I'd love to make one for my very warm and humid bedroom at least.
I like the fact he doesn’t use crayons or elaborate editing. We don’t need more of those youtubers who just want to entertain people who’d never attempt to build one anyways.
I'm glad you touched on the burner/heating - the whole time you were doing efficiency calculations I was worrying that you were ignoring the equivalent wattage if the burner
He's also ignoring the fact his evaporative "precoolers" are releasing heat and moisture into the room, which will in turn decrease the efficiency of the cooling. Of course, given how ridiculously underpowered the system is for the size of the room he's in, it would take many hours for that effect to reach a significant level, so it didn't show in his 30 minute test. As for the heater, equating cost with efficiency is pretty janky. With that logic, I could create the world's most "efficient" AC by simply powering a regular AC with solar panels which give you "free" power.
Hey - here is an idea: a final stack where you evaporate water in pre dried air. How about actually making the final stage a closed circulation and use water from it to be pumped into another radiator that takes air from the house and circulates it through it ? That way there is no contact of water and air that is being used for living space, so there should be no concerns of contamination. A small header tank with a floater could be used to replenish water directly from mains - after all water will be captured by desiccant and evacuated from the desiccant dehydration loop. Also I would suggest adding few coils of platinum here and there to inhibit bio growth in the system.
@@tommybronze3451 Copper is incredibly bactericidal as well. Studies have been being conducted for a few years now in hospitals etc. using copper or copper clad surfaces instead of bare stainless steel and found very promising results. And much cheaper to get results than the more rare and expensive metals.
@@newoneinblack and all those pc enthusiasts having a biological growth with their copper cpu blocks are just imagining stuff ? you want to kill bacteria AND fungi, and copper doesn’t cut it.
Im a tradesman in construction, and this look fantastic. Built with off the shelf components makes this useful anywhere. I noticed how you build the fan ports (very clever) and think I see a way to up the efficiency further. In each of the 3 columns, at the base, there is air restriction from the direction "sanitary tee". Air has to fight back around a roughly 120 degree corner. Clearly, it was used to keep the falling water from pushing out the air fan ports. If that tee was flipped in the columns, the air flow goes smoothly up. Comparatively, it could have a large effect on efficiency, for each stage of the process. The challenge now is preventing water from easily flowing out the fan port. This can be done several ways. At the first joint above the tee, install the bio ball screen across the pipe opening. Just below the screen, make a lip, splash guard or cone diffuser to direct water flow away from the fan port. Most designs can be 3d printed, or made from cutting different sized pvc pipe. That will add in a small amount air restriction, but still a respectable performance increase. It may be worth while to make the columns taller, to offset the 6"-12" of bio ball area changed from moving the screen up.

@@BrightMomentsNOLA Right? This is the most retarded thing I've seen in at least one week. Law of thermodynamics, you can't challenge or beat it. The energy turns to evaporation turns to cooler air, but it's crazy wasteful and not efficient.
We mix in a Calcium Chloride mixture into our caliche/dirt roads, so that they pull humidity in from the air and keep the road surface tacky. It helps keep the road flexible and will keep the dust down. It's some pretty cool stuff.
Town Guy Gaming great at keeping down the foliage too. Would never use this around farmers. The run off would kill the soil. In the rain it gets spread in the air and sticks on leaves. Salting the earth is bad.

Assuming the pre-cooler brings the input air temp roughly back to "room temp", I'm calculating pre cooled exit temp at about 19 degrees C w/humidity around 20%. Tech Ingredients.... If you still have the the fixture assembled, measures of humidity for each stage would be helpful to others. Thanks again for another great video.
Also when working out the COP, it's not a valid test without including humidity. Although humidity isn't super-easy to measure. Particularly in small quantities of air over short timescales.
@@greenaum humidity isn't a factor In determining COP technically. It's determined by cooling capacity of an evaporator relative to energy use of a compressor.
@@baxswisher7661 In this case, since it cools by adding moisture, the humidity would be relevant, since an ordinary AC doesn't add moisture. Indeed most ACs remove humidity, and that's usually a benefit, though it's not part of their stated job. Otherwise any bucket of water would have a COP of infinity, since it would cool down a room by evaporating.
Dealing with the heat wave now...This would be amazing. We have some always on computers that would be happy to contribute the desiccant cycle heat (which ironically need a few hundred watts removed from the room anyway). My only concern is the maintenance of configuring the 'grey' water evap system - would need a lot of flushing to prevent the high evaporation process from leaving a tonne of sediment clogging the filters. Very cool all around.
Is it really required? Wouldnt the osmotic pressure kill bacteria in the dessicant. The same can be done for the swamp cooler could it not. Much cheaper and more energy efficient
@@Th3_Gael fungal spores are unaffected by that, it's just a very good practice to add a UVC light on systems like this dealing with air people breathe.

As long as you make intake and exhaust at the ends. I ran a bunch of crypto miners like that for years and just dumped all the heat and most of the noise outside. Could have easilly put a heat exchanger in between if i wanted. You could even feed outside air into the rack if you don't want to use the air in the room because it does have to replaced somehow which usually ends up being air from within the rest of the house. That can be problematic when trying to heat the house in wintertime
Fascinating. My mind is currently mulling over other methods of heating the radiator without consumables and also how compact one could make this system. Instant subscribe.
2nd time I tripped over Tech Ingredients videos and both were mind blowing. Like being back in engineering school but better. Take the moment to subscribe to this "teacher".
Can't wait to see version two, with all the efficiencies you mentioned, and suggestion from the comments below, it could even be used for the third world, straight from solar cells. Great job is an understatement keep it up.👍
First World use is equally as important. Reducing our energy consumption is going to become paramount in the near future. I say this has global application
Of course - this is very exciting, I knew this had great deal of potential I never had time to work on these type of things. All of the science, lectures and working models im speechless.
They sell fans for computers that are high static pressure fans meant for using in liquid cooling with radiators as well. They're also very easy to find. But this is super interesting stuff, thanks again!
The high static pressure computer fans aren't really high static pressure fans when you compare them to hvac blower fans. Scale this thing up 10x and those fans make sense, and they're not terribly expensive.
@@jttech44 Oh no doubt you're right about that. My main intend was you're not limited to high volume fans at 120mm size (as shown in video) but could get high static pressure 120mm fans for your own needs if making a similar setup.

You remind me a lot of my physics professor in High School. That man was EXTREMELY overqualified for the position he held. He took that job to be available to care for elderly parents. At one point he was the ranking science officer on a submarine in the U.S. Navy and among the first people to go into Hiroshima after the atomic bomb. If you were not watching him as he taught his classes, you missed as much as half of his presentations. It was never "dull".

I live in a humid environment and have long since wondered what could be done to a "swamp cooler" to make it work in my area. Now I know.
Great video, brilliant science, thanks for sharing.
If it's modestly humid this could work pretty good but the dehumidifing will be less effective as the humidity increases, I think the system will start to fight itself in more oppressive humidity
6:37 Snow outside, the voigt tube speakers aren't completed yet. Looks like this video has been in the works for some time.
Snow outside also means he has a lot of dry air to boost up his "efficiency" =)
Canada.
I have the same concept of air-conditioning using latent heat of evaporation and I am happy to know somebody is also experimenting on it. I thought of that dessicant to dry the air but it will make the system complex it adds heat to the system that you will reject again later, lowering the system efficiency. Just make a cascade system. Separate the cooling medium and the air to be cooled so there is no need for dessicant. Natural dehumidification will occur just need to reach the dew point temperature. You can further improve its efficiency by removing the blower for the swamp cooler and put thermal stack (solar) on top of the swamp cooler discharge to draw air from the cooler (can be combined with blower when there is no sunlight). This system really works. Making the equipment smaller is the challenge.
Next video: "Hi. You might be wondering what this is. It is an oil refinery"
My exact thoughts.
"...with tropical hardwood inserts in the fractionating column made from reasonably priced, yet commonly available tropical plywood. This gives it pleasing acoustic properties so it can double as an efficient horn speaker"

"Today we have a DIY ultra-high frequency centrifuge for separating the tough stuff."
From its science to its engineering to its manufacturing to its materials to its economics.. full spectrum endeavors. Very cool!
@Tech Ingredients i'm an ventilation engineer and i really like your basic idea of that air conditioner. But i have to mention two things. First of all you can't calculate the watts of cooling by measuring the two different temperatures. You also have to measure the humidity of the inlet end outlet. You must calculate the coolingpower by the difference of
enthalpy. The second thing is, that you have liquids (warm liquids) in a circulation, that are in contact with your airflow. That could result in a hygiene problem. Keep on going with your really cool ideas :)
So; what do you think, is it more efficient and worth continuing?
The entire system would need to be completely sterile, yeah. All I could think the entire time was "Could you imagine trying to clean that thing?" Sponges evaporating on warm grey water, eugh... Cool concepts, neat idea, but I can't imagine how it would work for longer than a demonstration.
@@youthised58 I'm sorry but i'm not able to say if that build is more or less efficient, because i don't have the measurements. In the part where he calculates the COP i also miss the integration of the heat from the burners. This energy isn't free. To your last question: yes i think its worth continuing. The idea is great, but he should get some help with good scientific knowledge to get it accurate.
I thought that with the CFM (cubic feet per minute) and Delta T (sensible thermal difference) you can at least calculate the sensible BTU's of this. Once you have the BTU's you can covert them into watts by dividing it by 3.412. this is just the sensible heat in the system not the total. Also could the hygiene problem be fixed by adding some sort of cleaning agent to the water flow( without it affecting phase change properties) I don't know enough to determine if this applies to this system or is accurate. I would love to know more if you could shed some light on the matter.
For your second reasonable doubt, that there could be hygiene problems with warm liquids in contact with the airflow, I think I have the following solution (though it is a thought experiment): One could use a heat exchanger. This would preserve all the non-hygienic parts from the airflow itself and you had to clean only the condenser occasionally.
I'm so glad that y'all are putting out these very intriguing videos about topics that many people don't even think about. Keep up the great work!

I have been in the HV/AC feild since the 80's...and I found that if you sprayed a mist onto the condenser coil way back in the early 90's, that you could reduce the energy being used on that unit...and I then built a loop to surround my condenser coil..and attached my condensate drain line ( pump ) to the loop to spray water onto the condenser coils when the condensate pump need to empty, and this was short burst of savings...but it did reduce the amount of energy that was needed to power the ac. Now after watching this video, I think that you have helped me with a hump that I couldn't get over to save a lot more money on my electric bill.

Anyone aspiring to build or experiment with non-closed loop air conditioning systems in residential areas need to be aware of the dangers of microbial growth including legionnaires' disease which can be fatal.
Don't forget mold. Where I live, anything that stays damp for longer than a few days gets mold. The mold spores outside are incredible. No matter what I do, they still get into the house.
Would it be possible to add a chlorine system like they use for pools?
That' CaCl system is dehydrating and therefore antibiotic.
I wouldn't want my home smelling like a swimming pool as the chlorine evaporates into the air-doubt that's particularly healthy to breathe constantly either. Could add a submersible UV sterilization lamp to the final output tube to kill off any microbes before they exit. Would add to the power consumption, of course, and who knows how much heat it might put off. I doubt much would grow in the desiccant side, though, with such a high salt content.

Bro! Hold my beer! I live in New Mexico we use evaporative coolers to great success by drawing hot dry air over water soaked pads, Temp drop of over 30 degrees! Works great! Only thing is it adds humidity to the cooled air. But when your humidity is 14% you don't notice it. And you use a lot less electricity!
Sometimes I wonder about putting an evaporative cooler in the vicinity of my external compressor, to lower the ambient air it has to work with when it gets >100 or 105 degrees (California, dry heat). We can't get the house below 78 in these conditions. I can't find anything on this approach online, so maybe it is less effective than running the evaporative cooler indoors directly. I have tried misting and it does drop the temp a couple degrees, but can't be good for the health of the coils.
*Cries in 90% ambient humidity.
@@polylight a small sprinkler system spraying the condenser would work better, liquids have better heat transfer/absorption than gas.

Of course, given how ridiculously underpowered the system is for the size of the room he's in, it would take many hours for that effect to reach a significant level, so it didn't show in his 30 minute test.
As for the heater, equating cost with efficiency is pretty janky. With that logic, I could create the world's most "efficient" AC by simply powering a regular AC with solar panels which give you "free" power.
Hey - here is an idea: a final stack where you evaporate water in pre dried air. How about actually making the final stage a closed circulation and use water from it to be pumped into another radiator that takes air from the house and circulates it through it ? That way there is no contact of water and air that is being used for living space, so there should be no concerns of contamination. A small header tank with a floater could be used to replenish water directly from mains - after all water will be captured by desiccant and evacuated from the desiccant dehydration loop. Also I would suggest adding few coils of platinum here and there to inhibit bio growth in the system.
Copper not platinum.
@@newoneinblack actually silver not platinum, but thank for pointing it out.
@@tommybronze3451 Copper is incredibly bactericidal as well. Studies have been being conducted for a few years now in hospitals etc. using copper or copper clad surfaces instead of bare stainless steel and found very promising results. And much cheaper to get results than the more rare and expensive metals.
@@newoneinblack and all those pc enthusiasts having a biological growth with their copper cpu blocks are just imagining stuff ? you want to kill bacteria AND fungi, and copper doesn’t cut it.
Im a tradesman in construction, and this look fantastic. Built with off the shelf components makes this useful anywhere. I noticed how you build the fan ports (very clever) and think I see a way to up the efficiency further.
In each of the 3 columns, at the base, there is air restriction from the direction "sanitary tee". Air has to fight back around a roughly 120 degree corner. Clearly, it was used to keep the falling water from pushing out the air fan ports.
If that tee was flipped in the columns, the air flow goes smoothly up. Comparatively, it could have a large effect on efficiency, for each stage of the process.
The challenge now is preventing water from easily flowing out the fan port. This can be done several ways.
At the first joint above the tee, install the bio ball screen across the pipe opening. Just below the screen, make a lip, splash guard or cone diffuser to direct water flow away from the fan port. Most designs can be 3d printed, or made from cutting different sized pvc pipe.
That will add in a small amount air restriction, but still a respectable performance increase.
It may be worth while to make the columns taller, to offset the 6"-12" of bio ball area changed from moving the screen up.
Feel I learned a lot, thanks. No clue what I'm going to do with it, but that's the beauty of knowledge.
hahahaba
disappointing right? 😂
You're free to choose what you do with that knowledge - that's the fun part.
If you find yourself stuck on Gilligan's island, you're all set.
Well that's my daily cerebral exercise done, off to watch kittens chasing balls of wool now.
Watching these videos just makes me realise how much I don't know, i'm inspired, humbled, embarrassed all at the same time, but mostly I'm thankful to learn something.
@Mr Brightside Individual videos are better to an extent, but there are still issues with not having course tracks and accreditation, homework, curation and q/a. Also, physical interaction with a professor and peers is essential for holistic understanding.
You shouldn't feel embarrassed about not knowing these things! The concepts he's discussing are from chemical engineering and are not something most people would be exposed to. It's actually amazing that your interests brought you to this and that you watched it!
Well said.
I hate watching kittens, got any dogs riding skateboards?
Just want to thank you very much for your unsurpassed wisdom and research that you put into all of your videos! I truly appreciate YOU sharing and teaching your knowledge. You rock and all your videos are excellent without distraction ! Thanks!
For anyone who claims they've made a free energy device, I want a detailed demonstration like this
Lol... wait for the punchline.
Yeah, I wouldn't hold my breath brother. Lol
No such thing, if there were your municipal electricity provider would be using it to produce electricity to increase their profit, arguing against that fact would be foolish

This guy is like a real life Walter White, but a good one.....love this channel :)
for now.
Until I actually read about the real walter white.. I get that it's for the clueless as well as the bit more advanced.. but unfortunately the need to be so thorough makes for hard watching for me.. that get to the punchline or what you got new to say thang.. when we get to where we can cool 3500 sqft in arizona in the summer 115*F ... not need a extra garage for the unit.. enjoy the concept and your effort..!
99.57% pure air
This is such a played-out cliche for anybody with even a moderate degree of ability in applied science. It wasn't even a major part of WW's character after the first season when entitlement, greed, and revenge took over.
Walter White IS real. I saw he on TV...
I love how your videos make me watch several times, and then send me reading the theory form other sources. Some of the best content on youtube. Thanks for sharing your work.
What's your reading results? Do you think it's legit? Is there any commercial unit available using this concept?
@@bilalhasansyed7 Not much in the way of commercial units, bit lots of theory and papers available. This is legit... there are more efficient desiccants than salt... tri-ethylene glycol and potassium formate.... but potassium chloride is the easiest to use for experiemtation and handling. Google "desiccant cooling systems" and you will find plenty to read.
How new is this concept? I'm looking for a diagram somewhere, to compare to my own based on this video...
Congratulations! One of the best videos that mixes science and green energy or ways to be more efficient and less power consumer. The way you talk to the audience seem to be like a engineer to engieer conversation, which makes it very interesting (sometimes with so basic explanations gets boring). For me as a beginer in this filed it cost me a litle more effort to keep up with the explanation. If I'm allowed to make some suggestions, 1 Make and show some schematics and/or diagrams of the system. 2 If you can team up in projects of this magnitude with someone who can build a control and monitoring system electronically, overall you'll get a merchantable aircon system..... Such a great video!!!
Have you measured the room humidity before and after running this for some time? Also how much energy is the propane flame putting into the system?
He said it was about three times the electrical wattage used by the rest of the system.
It should be ~100W.
Too many energy inputs!
@@BrightMomentsNOLA Right? This is the most retarded thing I've seen in at least one week. Law of thermodynamics, you can't challenge or beat it. The energy turns to evaporation turns to cooler air, but it's crazy wasteful and not efficient.
@@AlfieMakes I think it's 69 units of WOO.
We mix in a Calcium Chloride mixture into our caliche/dirt roads, so that they pull humidity in from the air and keep the road surface tacky. It helps keep the road flexible and will keep the dust down. It's some pretty cool stuff.
Sounds like a recipe for rusty vehicles too!
Town Guy Gaming great at keeping down the foliage too. Would never use this around farmers. The run off would kill the soil. In the rain it gets spread in the air and sticks on leaves. Salting the earth is bad.
@@rosstemple7617 : Not sure of the effect of Calcium Chloride (as opposed to Sodium Chloride, ordinary table salt), but certainly I wouldn't want to be around that either.
@@rosstemple7617 Farmers have been using it for a long time. All of our tractor tires have it in them. That way the weigh more than just water alone in them. Also that prevents them from freezing.
Jared Maddox ha thank you. I know bleach is bad, not sure how much the calcium would neutralize it. Thanks again for the catch. For some reason(well ignorance) I thought they was the same. 🤪 LoL
Assuming the pre-cooler brings the input air temp roughly back to "room temp", I'm calculating pre cooled exit temp at about 19 degrees C w/humidity around 20%.
Tech Ingredients.... If you still have the the fixture assembled, measures of humidity for each stage would be helpful to others. Thanks again for another great video.
Also when working out the COP, it's not a valid test without including humidity. Although humidity isn't super-easy to measure. Particularly in small quantities of air over short timescales.
@@greenaum humidity isn't a factor In determining COP technically. It's determined by cooling capacity of an evaporator relative to energy use of a compressor.
When he calculates the power consumption he neglects to consider the power output used in the form of the gas used to heat the desiccant.
@@baxswisher7661 In this case, since it cools by adding moisture, the humidity would be relevant, since an ordinary AC doesn't add moisture. Indeed most ACs remove humidity, and that's usually a benefit, though it's not part of their stated job.
Otherwise any bucket of water would have a COP of infinity, since it would cool down a room by evaporating.
@@radbug He does address that later in the video - just keep watching :).
oce upon a time, i wanted to engineer and build just such a system - glad to see how it all comes together - thanks for elucidation sir
Dealing with the heat wave now...This would be amazing. We have some always on computers that would be happy to contribute the desiccant cycle heat (which ironically need a few hundred watts removed from the room anyway). My only concern is the maintenance of configuring the 'grey' water evap system - would need a lot of flushing to prevent the high evaporation process from leaving a tonne of sediment clogging the filters.
Very cool all around.
Excellent, Just missing the UVC LIGHT.
Good idea.
Is it really required?
Wouldnt the osmotic pressure kill bacteria in the dessicant. The same can be done for the swamp cooler could it not. Much cheaper and more energy efficient
@@Th3_Gael fungal spores are unaffected by that, it's just a very good practice to add a UVC light on systems like this dealing with air people breathe. Have you ever seen the gunk on most air conditioning systems while in use, there's a dirty oily mixture with a constant supply of dust fungi actually eat that stuff same with computer circuit boards, a simple UVC light says no to all them shenanigans.
I been doing some tests mounting an uvc lamp to the radiator of my aircon ( with an aluminium cover that left air pass but blocked the light) ... but gave it up again 2 days later since it started to smell real strange.
Uvc light seems to be really potent, but also have lots of side effects... was trying to install it in a wardrobe to sanitize my clothing... and ended up with all my black shirts getting a brown color burnt in where the light was shining on them...and all of them where black :(
@@donalain69 You are creating ozone which is very toxic. You shouldn't use sub 200nm UV lamps, use 254nm germicidal UV lamps, they produce a minimum amount of ozone.
Thank you Sir. Your unique and transparent demonstration efforts are surely appreciated by many of us who want to contribute something meaningful to improving energy utilization. Every little groundswell in this often ignored part of energy use has a significant meaning over time.
You trade in 'pipe' dreams that are real.
I got so tired of fake videos out there claiming free energy or something unrealistic by someone who knows nothing about thermodynamics or physics. Your videos are a breath of fresh air! Sure, there are some times where I'll disagree but at that point I'll be nit picking over a video that I enjoy so much. I'm always impressed by the technical considerations that went into the experiment or the design of the equipment that's in the video. Beyond that, you are an inspiration! I'm sure there are hundreds, if not thousands, of viewers who just went with an idea that they weren't confident about and made it happen because of this channel.
Thank you, I genuinely hope so!
Engineers really are a different breed. I can't quit watching...
Amazing concept, amazing guy... but also amazing cameraman - you could see everything that was explained and talked about in good detail the entire time.
I noticed this as well. Cameraman knew exactly where to be at all times! Especially when he was in between the two pipes...I thought he made a mistake, but nope the presenter showed right up there a few moments later! :) Maybe perhaps it was a little rehearsed beforehand but I'd like to believe they both are just naturals and great at what they do. Well done. 👍
So, apparently the youtube recommendation algorithm thinks that I need to build myself a new A/C unit.
fishin freak the algorithms make me learn more
Google has chosen you to have air conditioning during the apocalypse. You are blessed.
Mine too....Google wants my wife put me inside that bunch of tubes (in the best option I guess...)
or thinks you'd be interested in learning about it
I know right
I love your work and will be looking forward to improved iterations. I saw another homemade ac on UA-cam but it was very inefficient, as it used ice to cool water that was circulating in a copper pipe, Infront of a fan. You on the other hand have hit the nail in the head in terms energy efficiency. Keep up the good work!
Most of my country is extremely hot in the summer, nearly inhospitable. I've found that compressed stabilized earth bricks are great at regulating indoor Temp and humidity. For flourishing agriculture, the best I can think of is rain water harvesting.
As a chemical engineering student, this video is great fun to watch! Thanks
hands down, this is one of the best videos i've ever watched. so much great information and practical explanation. thank you.
It would be nice to see the relative humidity in the room and at each of the stages.
maybe the air dryer evaporators could be placed outdoors, or vented to the outdoors to deal with the water vapour these produce
I think that the idea, considering that it uses descendant to dry the out-flowing cool air. Otherwise, it's just a swamp cooler (as he points out in the beginning)
@@jaxonrickel5499 Yeah but he is cooling the desiccant and the water with evaporation using the room's air. That evaporative cooling would decrease significantly in a humid environment.
@@rgebishop
dry air from the room
then cold humid air
then descendant + dry cold air to the room
if he insert air from outside, it needs to be always dry air and you will not need all this system
because there are water air conditioners in the market which will not cool in humid weather
This is absolutey Genius! Thank you very much for demonstrating the system you have developed and the evaporative cooling process.
I really like the presenter speaking skills, but a diagram would be helpful.
That and a parts list.
@@i-love-comountains3850 not exactly, but it's hard to follow what happens in each column & tray.
I was thinking the same thing. And also he could do a diagram with some animation to help illustrate the flows and morments of air and water.
I gues its patent pending
AFAIK you can only patent something if it's not public yet
You won me over. This video alone has made me a subscriber. Thanks for the video!
“Pine” - lol
Love your videos. Keep up the good work!
23:00 "pine"
28:35 "free energy"
HAHAH i laughed and came to comment about that too . "pine" ha
Thanks so many for sharing this. I'm from Brazil and I will try to implement this concept in my home.
Perhaps if used in a data centre then the heat for the desiccant process can be supplied by the heat from the CPU's using on chip liquid heat transfer.
Most datacenters actually use an evaporative process.
John Laban Keep saltwater away from electronics (it's conductive), electricity (it makes bad stuff under electrolysis) and steel / iron (accelerated corrosion).
you can just blow the hot air trough a heat exchanger though. No need for water cooling any servers.
@@baronvonlimbourgh1716 Can you make a video of that? My room gets too warm due to too many PC power supplies running. I have plenty of hot air in my attic even with roof ridge venting.
@@MrJerryjam if you put them in a server rack and cut a round hole in the top you can attach a flexible hose and a workshop blower to it.
At that point you can lead the hot air to wherever or through whatever you want.
Does not have to be a server rack though. An old closet or a custom build enclosure will all do the trick. As long as you make intake and exhaust at the ends.
I ran a bunch of crypto miners like that for years and just dumped all the heat and most of the noise outside. Could have easilly put a heat exchanger in between if i wanted.
You could even feed outside air into the rack if you don't want to use the air in the room because it does have to replaced somehow which usually ends up being air from within the rest of the house. That can be problematic when trying to heat the house in wintertime
Thank you for sharing such knowledge for free.. hope this caught on large scale as it will be a significant drop both in cost and power..
Thanks... I followed the whole thing and now have one running in my 1962 Chevy II Nova.
Fascinating. My mind is currently mulling over other methods of heating the radiator without consumables and also how compact one could make this system.

Can't wait to see version two, with all the efficiencies you mentioned, and suggestion from the comments below, it could even be used for the third world, straight from solar cells. Great job is an understatement keep it up.👍
First World use is equally as important. Reducing our energy consumption is going to become paramount in the near future.
I say this has global application
Of course - this is very exciting, I knew this had great deal of potential I never had time to work on these type of things. All of the science, lectures and working models im speechless.
Who is this man?
What does he do?
Where did he get this million dollar lab mountain retreat?
I have these questions every time I watch a TI vid.
Probably an engineer who does facilities management...
He bought pvc and air duct fans from Lowe's. It's nowhere near a million dollar lab.
Not sure but it's cool! LOL
Regardless of the cost, it's a beautiful lab.
DIY vids that show you how to build a chair to save money... Provide you have hundreds of dollars of equipment and tools first. Lol
They sell fans for computers that are high static pressure fans meant for using in liquid cooling with radiators as well. They're also very easy to find. But this is super interesting stuff, thanks again!
The high static pressure computer fans aren't really high static pressure fans when you compare them to hvac blower fans. Scale this thing up 10x and those fans make sense, and they're not terribly expensive.
@@jttech44 Oh no doubt you're right about that. My main intend was you're not limited to high volume fans at 120mm size (as shown in video) but could get high static pressure 120mm fans for your own needs if making a similar setup.
