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".

@@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. From what I've read it would last a long time underwater. I Don't know why we don't make everything out of platinum honestly. People seem to like it.

@@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 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.

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
airflow turbulence will only be a factor until the system is filled and at pressure. in fact, that turbulence is what assists the interaction between water and air crossflow.

I love your work and will be looking forward to improved iterations. I saw another homemade ac on RUclips 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.
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.

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.
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.
@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'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.
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.

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.

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!!!

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.

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.

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.
Getting a lot of nostalgia for Mr. Wizard, but meant for adults. You did manage to cover most of the "but what about" thoughts that I had (using waste heat to dry the desiccant is a good move. CHP systems or really any of the absurd amount of waste heat we produce really drops the cost) but I either don't understand the concept of your evaporation tanks, or think the enthalpy of evaporating water would change your thermodynamic performance a bit. I have no doubt the system works, as you say dehydration cooling, even with salt spray, is a relatively old technology, and systems having hot and cold sides are rather required to move heat around, but you really glossed over those evaporative tanks' effect on the system as a whole. Are they a cost saving measure over simple radiators on the hot side? I'm all for field-expedience, but the fan consumption for radiators at the low power consumption you're discussing can be considerable. Still a wonderful proof of concept. Thanks!
Truly excellent presentations, I've watched both several times to ensure I understand each component. I'm intending to fabricate this system and have a question. You suggested a concentration of 35% calcium chloride. I assume this is by weight? What concentration of lithium chloride do you suggest? In the system you show here, approximately how much total fluid is circulating? Thank you sincerely for your channel - I am learning so much from you. Greetings from England (the system I build will be in Spain).
I think you can start with any concentration. If your solution is too strong, the water it absorbed will not dry out until it reaches equilibrium. If your solution is too weak, it will only start working once the dryer has enriched the solution sufficiently.
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.

Otherwise any bucket of water would have a COP of infinity, since it would cool down a room by evaporating.
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
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.
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.
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.
@@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.

Brilliant, I can feel the passion for what you are doing. Thank you so much for sharing that amount of knowled, present it in a way that we people can understand and use.
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. 👍
Absolutely a beautiful presentation . I had purchased a portable evaporative cooler for ham radio use in the field here in south Texas well I decided to use it in my house since my electricity bill was sky rocketed and a strange thing I noticed , it was a little to humid to be any good but I was able to dry out the air by settling my AC on 83° then using the evaporative cooler which brought the ait temp down another 10° and I'm not cycling the AC near as much this is a savings for me without a lot of effort.
Thank you sir for the effort and time you put into this video. Just recently discovered your channel and am excited to go through the whole lot. Working on a solar absorption cooling system using LiBr as the working fluid. Am interested in building this system and study its performance with respect to Northern Cyprus weather condition. A schematic and pdf of parts will be very useful because am still learning how this whole thing works. Am interested in HVAC and so, I feel projects like this will really help me be a better engineer.
To regenerate the dessicant liquid? I wondered how he'd do that, and the same idea occurred to me. I'm still only halfway through. It'd benefit from a few animations, it doesn't spring to mind fully-formed as he tells you it. I get what he means for each stage but the whole thing together isn't obvious.
@@greenaum I've read that in Freiburg, Germany, part of the Solar Info Center is rented to a company called Fraunhofer ISE: "Within this part, an area of offices and a seminar room is air-conditioned by a liquid desiccant cooling system, driven in a solar thermal autonomous cooling mode. It is a pilot system to demonstrate the applicability of this technology."
So with all the water running through this what steps/precautions would you need to take to prevent it from getting all gunky and disgusting with growths? Alternatively, if that's unavoidable, how often would it require cleaning and how intensive would that be?
I guess there is nothing that can grow in a 36% brine. For the water you could add chemicals like they are used in camping vans to keep the tanks clean.
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!
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
Why did I found this channel so late? I've studied power and energy technology, love the way you're explainig everything in your videos. Knowladge you have is impressive and I don't see any flaws within a sciance you show on here. Greetings from Poland!
This "masterpiece" that is neither revolutionary nor something any sane person would want to have - there is a reason why we use closed loop systems normally and only with very strict regulations open loops are allowed to be sold. But sure, if you do not have kids, go ahead and try it.
Ok, so say I wanted to build one of these.... A couple of questions: 1. What concentration of salt is needed for the desiccant solution? 2. I assume the two evaporative baths exhaust some (all?) of the waste heat, so these would vent to the outside, but what about the first (desiccant drying) stack? Does that need to vent to the outside as well? 3. If I wanted to increace the cooling, would lengthening the stacks, or using larger-diameter pipes be more effective? Unless I'm misuderstanding, this is still a heat pump of sorts. I can see the air that goes through the second two stacks forms one side of the pump, I'm struggling to figure out exactly whcih components are the other....
I definitely think I need to diagram this, it is all well explained but I need to visualize how each stage of the process goes (energy in and out, etc). It will likely take some time since I'll need to review prior videos as well as additional information (consulting the reliable "Handbook of Chemistry and Physics"). I will try but don't know how long it might take me.
@@TomMeehanMake thanks for the excellent video content! I agree; while the explanation was phenomenal, a quick schematic would definitely help with comprehension. Have you tried coarse perlite instead of plastic? The surface area would be orders of magnitude larger, and it's far cheaper and lighter than the bioballs.
Jens - I agree. There was too much "This, then this, then this, and so this..." too many details without an overview, and too much of an overview without a roadmap of what the system itself is. There's probably 6-10 simple things going on here, but it hasn't been explained in a simple way that someone could grasp the first time.
@@StevenCampbell1955 I'm not sure, that's why I asked! Compared to the aquarium doodads, perlite's surface is superior at holding and releasing water, so you could likely use far less volume of it, but at the cost of it being harder to push the air through... that said, I've seen perlite come in chunks as large as a quarter, which may have a more optimal airflow:evaporative surface ratio... or maybe a mixture of perlite chunks and aquarium doodads would be the best. Only one way to find out!
if the average American would be able to understand what this guy is talking about, there probably never would be an apocalyptic event ( at least not one that is caused by humans)..
You have the best RUclips Channel. You speak clear and concise and capable of explaining without the unnecessary technical lingo so you keep viewers engaged. This approach is so underrated and passes knowledge that can actually be absorbed. Thank you.

@@javiersierra6887 Tromp ac is even more efficient.
Fairly sure the swamp coolers used in desert or low humidity areas are the same.
@@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 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.

airflow turbulence will only be a factor until the system is filled and at pressure. in fact, that turbulence is what assists the interaction between water and air crossflow.

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.
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.

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.
Would it be possible to use a UV system in your stacks to help with microbial growth?

Thank you, I genuinely hope so!
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.
Water is a truly a remarkable liquid. Your presentations are also remarkable. You take the phrase, "Be like water" to heart.
@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 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
And with the burner he is literally heating the room's air
fuck...I'm complete... thank you for bringing that up.
@@lucamusso3551 The system in operation wouldn't be inside the room...
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.
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
What about using some heat sinks into the pipes connecting them to the cool side of a bunch of pelter elements to condensate the humid air in the pipes? Thanks

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!!!

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.

2) What pumps are you using?

Good idea.
Is it really required?

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.

@@ses4068 technology scales. Physics don't. I don't really see the point of the question, but I also don't expect this system (including the air columns) to be scaled to the size of a backpack ever and still give the same amount of cold air. That's simply not how it works.
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. 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.
@@polylight they make coil cleaner for that i think you might have to get that from a ac supply house, or you could also use diluted clr, and that stuff really eats through deposits.
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.

Getting a lot of nostalgia for Mr. Wizard, but meant for adults.
You did manage to cover most of the "but what about" thoughts that I had (using waste heat to dry the desiccant is a good move. CHP systems or really any of the absurd amount of waste heat we produce really drops the cost) but I either don't understand the concept of your evaporation tanks, or think the enthalpy of evaporating water would change your thermodynamic performance a bit.
I have no doubt the system works, as you say dehydration cooling, even with salt spray, is a relatively old technology, and systems having hot and cold sides are rather required to move heat around, but you really glossed over those evaporative tanks' effect on the system as a whole. Are they a cost saving measure over simple radiators on the hot side? I'm all for field-expedience, but the fan consumption for radiators at the low power consumption you're discussing can be considerable.
Still a wonderful proof of concept. Thanks!
hands down, this is one of the best videos i've ever watched. so much great information and practical explanation. thank you.
And is there any way possible you can make a step by step video on how to make this? I really like this idea
This was a step by step video.
Truly excellent presentations, I've watched both several times to ensure I understand each component. I'm intending to fabricate this system and have a question. You suggested a concentration of 35% calcium chloride. I assume this is by weight? What concentration of lithium chloride do you suggest? In the system you show here, approximately how much total fluid is circulating? Thank you sincerely for your channel - I am learning so much from you. Greetings from England (the system I build will be in Spain).
Where in Spain would you do it? Only to see in person if you agree!
I think you can start with any concentration. If your solution is too strong, the water it absorbed will not dry out until it reaches equilibrium. If your solution is too weak, it will only start working once the dryer has enriched the solution sufficiently.
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.
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 :).

Absolutely a beautiful presentation . I had purchased a portable evaporative cooler for ham radio use in the field here in south Texas well I decided to use it in my house since my electricity bill was sky rocketed and a strange thing I noticed , it was a little to humid to be any good but I was able to dry out the air by settling my AC on 83° then using the evaporative cooler which brought the ait temp down another 10° and I'm not cycling the AC near as much this is a savings for me without a lot of effort.
Thank you sir for the effort and time you put into this video. Just recently discovered your channel and am excited to go through the whole lot. Working on a solar absorption cooling system using LiBr as the working fluid. Am interested in building this system and study its performance with respect to Northern Cyprus weather condition. A schematic and pdf of parts will be very useful because am still learning how this whole thing works. Am interested in HVAC and so, I feel projects like this will really help me be a better engineer.
Do you have an update? This sounds like a really interesting concept. I am interested in compressor-less systems as well.
A really good explanation. I like the idea of the German company who is using the hot output to drive the desication process.
To regenerate the dessicant liquid? I wondered how he'd do that, and the same idea occurred to me. I'm still only halfway through.
It'd benefit from a few animations, it doesn't spring to mind fully-formed as he tells you it. I get what he means for each stage but the whole thing together isn't obvious.
I'd actually like their name ..
@@greenaum I've read that in Freiburg, Germany, part of the Solar Info Center is rented to a company called Fraunhofer ISE: "Within this part, an area of offices and a seminar room is air-conditioned by a liquid desiccant cooling system, driven in a solar thermal autonomous cooling mode. It is a pilot system to demonstrate the applicability of this technology."
@@ThatWord Fraunhofer is a research society, does anybody know the actual name of the company that produces them?
So with all the water running through this what steps/precautions would you need to take to prevent it from getting all gunky and disgusting with growths? Alternatively, if that's unavoidable, how often would it require cleaning and how intensive would that be?
Throw in hydrogen peroxide in the water every week or month or year?

I guess there is nothing that can grow in a 36% brine. For the water you could add chemicals like they are used in camping vans to keep the tanks clean.

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

@@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.

But sure, if you do not have kids, go ahead and try it.
Ok, so say I wanted to build one of these.... A couple of questions:
1. What concentration of salt is needed for the desiccant solution?
2. I assume the two evaporative baths exhaust some (all?) of the waste heat, so these would vent to the outside, but what about the first (desiccant drying) stack? Does that need to vent to the outside as well?
3. If I wanted to increace the cooling, would lengthening the stacks, or using larger-diameter pipes be more effective?
Unless I'm misuderstanding, this is still a heat pump of sorts. I can see the air that goes through the second two stacks forms one side of the pump, I'm struggling to figure out exactly whcih components are the other....
Is there any way you could provide a drawing of this?
I could see it ten times and take notes... but Please :-)
I definitely think I need to diagram this, it is all well explained but I need to visualize how each stage of the process goes (energy in and out, etc). It will likely take some time since I'll need to review prior videos as well as additional information (consulting the reliable "Handbook of Chemistry and Physics"). I will try but don't know how long it might take me.
@@TomMeehanMake thanks for the excellent video content! I agree; while the explanation was phenomenal, a quick schematic would definitely help with comprehension.
Have you tried coarse perlite instead of plastic? The surface area would be orders of magnitude larger, and it's far cheaper and lighter than the bioballs.
@@petertrzos6645 Would there be enough air flow through perlite. As it is granular and would need a higher air pressure.
Jens - I agree. There was too much "This, then this, then this, and so this..." too many details without an overview, and too much of an overview without a roadmap of what the system itself is. There's probably 6-10 simple things going on here, but it hasn't been explained in a simple way that someone could grasp the first time.
@@StevenCampbell1955 I'm not sure, that's why I asked! Compared to the aquarium doodads, perlite's surface is superior at holding and releasing water, so you could likely use far less volume of it, but at the cost of it being harder to push the air through... that said, I've seen perlite come in chunks as large as a quarter, which may have a more optimal airflow:evaporative surface ratio... or maybe a mixture of perlite chunks and aquarium doodads would be the best.
Only one way to find out!
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
This is my favorite channel on RUclips....!!!!!!!!!!!!!!!!! And I feel proud saying that....
These guys would be the only ones with ac in a Apocalypse level event.
Well them and about a tenth of those who watched this video and will try it out... I'm gonna give it a shot.
Not only ac but they probably have a self contained secret bunker under their house.
if the average American would be able to understand what this guy is talking about, there probably never would be an apocalyptic event ( at least not one that is caused by humans)..
Run off car batts for days being recharged with solar ofcourse

Also different politicians running the place.
You have the best RUclips Channel. You speak clear and concise and capable of explaining without the unnecessary technical lingo so you keep viewers engaged. This approach is so underrated and passes knowledge that can actually be absorbed. Thank you.
I saw an ad today on You Tube from a company selling air conditioners that use a new technology, and it looked like they were using a short clip from one of your videos, and I think it's this one. The advertiser was "Chillwell." I thought I'd bring this to your attention incase they were using it without your permission.
