1. boil rich a water/ammonia solution in a small tube off of the main resivoir of such. Vapors rise towards a condensor. 2. before reaching the ammonia condensor most of the water vapor condenses and drips down into another pipe containing mostly water and just a bit of ammonia (Pipe B). This is the poor solution. 3. Seperated ammonia vapor travels on its own to the condensor where its heat is absorbed into the air behind/under the fridge. 4. Condensed liquid Ammonia drains down into the inlet of a "U" shaped vapor trap (like a "P" trap under a sink), as it does so it makes that amount spill out of the outlet. 5. As the liquid Ammonia comes up out of the outlet it meets hydrogen gas which is similarly being forced out of its own outlet by pressure at its inlet. 6. The hydrogen gas and liquid ammonia react, rapidly turning the ammonia into a gas again as it goes through the evaporator. Per Boyle's law, the rapid change in volume is endothermic and makes the evaporator piping and heat sinks cold, absorbing heat from the air in the indisde of the fridge. 7. after the evaperator, the gaseous solution is advanced downwards into the gas filled top half of the rich ammonia water solution tank and then upwards into a pipe that zigs back and forth. This pipe is called the Absorber. 8. While this gas is going updards in the absorber, the water that was seperated from the rich solution after the intial heating (step 2) water trickles down the absorber pipe and pulls the ammonia gas out of solution w/ the hydrogen gas. The water/ammonia liquid solution then drains back down into the rich solution tank and the pure hydrogen gas continues on alone into the inlet of its upside down "U" shaped pipe. This pressure on the inlet of the pure hydrogen gas pipe is what was displacing hydrogen out of the outlet to mix w/ the liquid ammonia in step 6. Dang, simple as I could make it. Whoever came up w/ this should be remembered for time immemorial.

And when they don't work after you haven't been using them for a while, you turn them upside down for a few minutes then back to normal position... I was stunned when I saw this, it is the most counter intuitive thing to a refrigeration technician
right side of "pipe B" in green on the right, the vertical part that is directly above the burner, is it like split in to two vertical tubes? If so, why? Or is it just a single veritcal cylindrical tank but is pictured with the burner flue in front if it? Or does the burner flue go up through its center as a fire tube boiler? Why would you want to heat the poor solution resivoir? Wouldn't you want to keep it cooler so the water vapor can distill of the vapors rising from teh rich solution tank?
The most efficient way would be to use the sun directly to boil the water/ammonia mix, as opposed to turning the light into electric then using an electric heater. It would be more complex, but a salt solution would be able to be heated by solar energy then that salt solution could in turn boil the refrigerator's mix. Or you can get really complex and figure a way to have the burner in black-body panels that get heated with the sun. I know this would require a lot of insulation as the hours of operation would be limited. That would be so interesting to see though.
Would have been a little better if the animation labeled or highlighted (or flashed) the section of the pipe that the naration talked about. It did this in 1 or 2 places, but would have been really helpful if the author could have done it for the whole explanation..

I like that idea of powering absorption refrigeration with evacuated solar tubes. I'd be thrilled to do that. Beyond that, it gets too complicated for me.
Why does the bottom liquid outlet pipe of the rich solution tank (A/white) have to be routed though a water jacket pipe filled with the poor ammonia solution (B/green)? ...I suppose the water jacket on the left of the warming chamber keeps its water cooler than the water in the pipe that comes out of the right side of the warming chamber. That way the ammonia/water vapors do not try to travel to the left upinto the rich solution resivoir tank???
Ananta Sesa das the system is sealed and it is constant pressure, I mean when the burner is running the pressure of the system increases but pressure is equalized throughout the whole system there is not a bias that could operate a check valve in the system
+John Smith i was thinking that pressure was increased but how a check would force the pressurized water vapor and ammonia vapor to only go out the left side. _i __-now-__ (edit: don't) think that the pressure in both directions can be a help._
Ananta Sesa das it's been a few months since I looked at it so I would have to review it but what is creating the flow is differences in temperature between different parts of the system and different things going into and back out of solution then either blowing up as a gas or down as a liquid and flowing in One Direction and not the other because of liquid pooled up in the bottom of U bends
right. that's my understanding as well. i think i was wrong in guessing that back pressure might help on the left too though. the vacuum that pulls ammonia from the evaporator could be (?) produced by the formation of solution from ammonia with the poor mixture of water and saturating it to then take up less space. also the water jacket that cools the left must be reducing the amount of ammonia evaporating out of solution in the white liquid (rich mixture) on that left side. i can see why baffles or one way valves even with very little resistance wouldn't be a help. the idea is to get the ammonia to evaporate over near the burner (right side) so it can start it's commute to work.
what kind of efficiency do these coolers get? IE ratio of BTU of heat put in to BTU of cooling power on the other end? also what temperatures are required to start the reaction?
that depends on what you use to make it work , did you know that you can use wood , old used motor oil or used canola oil or a gasifier to make this type of a fridge / freezer work ? it can be used in the bush no electricity needed ac or dc not needed , you will need the proper system to push the heat from the wood , oil , gas ect to make it work , its all on youtube, the how to do it , and the best thing about this type of cooling system is it works silent , no sound except for the click when it turns on and off , very efficient when it comes to its handyness , according to how long my small propane lasts the efficiency i say is outstanding
That is the basic idea behind a heat pump. The same is true for the compressor in your fridge. It's just the fire is removed from the ice by several intervening steps and many miles. You use heat at the power planet to generate pressure which you use to do work and generate electricity. Then your fridge uses electricity to do work and run a compressor to generate pressure to drive a temperature differential.

I also would like an explanation of what is happenign in the evaporator. I understand how pressure at the inlet of both the pipes containing liquid ammonia and hydrogen gas are forcing both to meet at their outlets. I suppose the hydrogen gas pipe outlet is actually just below the surface of the ammonia liquid and it the gas bubbles through the liquid and that this causes a chemical reaction which causes a gaseous solution and this change in volume from a liquid to a gas would be endothermic per Boyle's law?
This was a wonderful explanation the video gave. Much better than other videos that end up in the search. It's not about pressure, it's about temperature. The process exploits the energy needed to turn ammonia from a liquid to a gas--what the hydrogen is a catalyst for in the evaporator.
@@lightdark00 The hydrogen is definitely not a catalyst. No chemical reactions are occurring here. Hydrogen gas over liquid ammonia lowers the partial pressure of ammonia gas above the ammonia liquid, so the liquid ammonia boils easier. The cold space gives heat to boil that liquid ammonia.
“There’s only two pipes in the system” pipes A,B,C,D,E,F,GH,I,J,K, and L
This is the best explanation I've found so far. Thks
Thanks that was good ! I always wanted to know how that functions. Quite elaborate actually. I had one of these when i lived "off grid"
1. boil rich a water/ammonia solution in a small tube off of the main resivoir of such. Vapors rise towards a condensor.
2. before reaching the ammonia condensor most of the water vapor condenses and drips down into another pipe containing mostly water and just a bit of ammonia (Pipe B). This is the poor solution.

BEST EXPLANATION YET!!!!!

Why would you want to heat the poor solution resivoir? Wouldn't you want to keep it cooler so the water vapor can distill of the vapors rising from teh rich solution tank?
it IS cooler by being farther from the flame. the extra heat might help release more ammonia. but still be too cool to boil the water in solution.
ist possible to use sun heat instead of gas burner ?
that's what led me here. some people did just that.
You can use a solar powered heater.
The most efficient way would be to use the sun directly to boil the water/ammonia mix, as opposed to turning the light into electric then using an electric heater. It would be more complex, but a salt solution would be able to be heated by solar energy then that salt solution could in turn boil the refrigerator's mix. Or you can get really complex and figure a way to have the burner in black-body panels that get heated with the sun. I know this would require a lot of insulation as the hours of operation would be limited. That would be so interesting to see though.
A heat source is required to boil the solution, this is also done with an electric element.
If there is distilled water in one pipe, will the fridge be destroyed if I leave it in a unheated cabin where it can go down to -30'C in the winter?
Hi Zforce69, its mostly distilled water (item B) - 1:11 into the video.
Why the distracting noise (music) are we not capable of listening without it?
Would have been a little better if the animation labeled or highlighted (or flashed) the section of the pipe that the naration talked about. It did this in 1 or 2 places, but would have been really helpful if the author could have done it for the whole explanation..
Could one use mirrors focusing the sun to power such a system?
Yes, or solar vacuum tubes since they should work better in indirect sunlight. Perhaps sodium heatpipes to transport the heat to the generator/boiler.
Pykrete cold storage vessels could be used to make an air conditioner.
as soon as i hear a robot voice, i'm gone.

even a solar energy concentrating parabola mirror was used in one example.
It's approximately 60% efficient
