How does the electricity-free Coolar refrigerator work?

Explanation of the field test unit of Coolar's electricity-independent, 100% water-based off-grid refrigerator.

[@ComplexAtom]

I love that you guys made something to actually help us instead of trying to put all of these gadgets and charge everyone an arm and a leg

[@HighWealder]

I remember seeing a video of an Indian company making ceramic fridges that cooled by evaporation of water.

[@gauravbundel4413]

Yes it's called mitticool. Better & practical. Costs around 8000/-.. Around 90 usd

[@diegoalcantaras5580]

yeah, kinda makes me wonder if maybe india had better economy they couldve refined it more and then released it internationally before these europeans did lol

A great innovation. I wish you great success for the future gentlemen. 👍

I'm so happy that after so long research i found your video ! I'm myself trying to cool a chest freezer with my car's roof, or motor wast heat.. You can even use this dessicants material to store chemically heat of the day / summer for when needed !! I want to cooperate ! There is so much to do with intelligence and the heart ! Everywhere i walk i can see underrated sun captors ! Roofs, cars, roads...

You should let me test that here in Florida.

Same here, with higher humidity we don't get as good of evaporation, would work alot better in the desert. I'd be will to test one for a year if they would let me. Or do they even read these comments ?

[@d.Cog420]

What temperatures can it cool to? And does it work equally well on hot and cold as well as dry and humid climates? Evaporation cooling usually struggles with high heat and humidity. Also, how do you control the cooling temp range? Awesome idea.

[@GabriellaWarupi]

Hi guys am from PNG and am interested in what you are doing, hope to see more

[@frostyfrances4700]

Hope you get something affordable for US home use b4 my old frig conks out. I guess the Coolar would have to be stored outside so venting the heat wouldn't turn the house into a slow cooker? Still under shade would probably be good if the solar part could be extended beyond that. I'm thinking covered porch.

[@spacecaptain9188]

Is this something we can diy at home, during quarantine? It sounds like it's simple to rig up.

[@NotSure416]

Can this be scaled up to cool a building?

[@truthseeker9688]

What is the minimum temperature achieved with this system?

[@tetrabromobisphenol]

A better question would be to see Q versus delta T curves. There's plenty of things that can get down to insanely cold temps (e.g. Peltier junctions) but they can only move 1W of heat or less, so they're only useful to e.g. cool a CMOS sensor. A practical fridge on the other hand needs to be able to move 100W or more of heat to prevent spoilage.

[@Johny40Se7en]

So it keeps stuff cool inside, and keeps the room warm on the outside thanks to that big radiator, nice. Very clever.

[@Drew.Murdaugh]

How many degrees below ambient temperature can it achieve? Sounds like a good off grid cooling unit refrigeration unit I mean how big is the cubic feet of storage? I like how the coolant probably works on convection. I don't understand the desiccant or the vapor draw but I could learn sounds very interesting

[@TheNorthwestForager]

Incredible design 👏 For on-grid/electrical use could the solar panel be replaced with a low amperage pump?

Well its only a step away from the old kero fridge or the 3 way RV fridge by function

[@n113hadi9]

the fridge doesn't need electricity, the solar heat does. how you trasfer the heated water without pump?

[@TrashPanda71]

Hot water rising in the panel, draws the cooler water into it.. therfore as long as the sun heats it up you have circulation.

[@n113hadi9]

@@TrashPanda71 that's the basic principle. In order to apply that in the system a certain condition needed. For example "oil immersive HV Transformers." Watch the video, it's hard to achieve fluid circulation with that setup(small diameter pipe, and position).

[@Cryptosifu]

[@jackbailey3263]

[@tetrabromobisphenol]

The only downside I see to this is that you have to use live steam to dry the silica. Which means installation in any developed country HAS to be done by a certified boiler operator ($$$), even if it's just to tighten two compression fittings together. So...maybe relax the "no electrical power consumption" constraint just a little and allow for the two silica streams to be transported between two otherwise sealed units. Then anyone can do the install, significantly driving down ownership cost.

[@fjs1111]

Absorption cooling is not new, some refrigerators use natural gas for heat source and ammonia as the refrigerant. As you know, industry uses this method too in co-generator and waste heat transfer. Who is going to leave a refrigerator out in the sun? And if you mount the panel far away from the refrigerator you are going to have high heat losses. I realize this is a bit critical, but electricity is efficient and more practical combined with a solar panel then this method.

It is not electricity free if you use a solar panel. It may be off grid, but if the panel breaks and you cant get a new one.,, then what?

[@kaosumaru]

It appears the "solar panel" is not generating electricity but hot water which evaporates the water from the silica gel, returning the vapor to the condensation chamber. So if the panel "breaks", put it back together. Idk.
