“There’s only two pipes in the system” pipes A,B,C,D,E,F,GH,I,J,K, and L

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.

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"

Its a simple representation used to explain the process, not meant to be a training video. If you have a more detailed video or explanation you would like to share please do.

omg who is resposible for the sound ?

What about that green thing on the right?

Why the music? It's so distracting.

Great explanation - thanks for the upload.

BEST EXPLANATION YET!!!!!

Hi Zforce69, its mostly distilled water (item B) - 1:11 into the video.

A heat source is required to boil the solution, this is also done with an electric element.

Pipe L, does it duct hydrogen to the outside in case of overpressure?? How does work exactly??

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

ist possible to use sun heat instead of gas burner ?

I'm so grateful! really I never could understand it B4

Why the distracting noise (music) are we not capable of listening without it?

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?

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?

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..

Pykrete cold storage vessels could be used to make an air conditioner.

Could one use mirrors focusing the sun to power such a system?

as soon as i hear a robot voice, i'm gone.

Why not retrofit a solar vacuum tube set up to heat gallium to run a absorption refrigeration unit and run a thermal electric generator and make a stand alone air conditioning unit? Novartis

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???

How hot does that flew need to get to make the gas compress?

Ice from fire!!

Lifes to short to get your head around this guff!!!

This video might have been helpful if it didn't have the music.

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's more than 2 pipes

Got all that now? (Still scratching his head) :-/

Absorption refrigeration is used worldwide but try to find a good tech.

So how can I use a burger?

lol you lost me @ 1:00

What if there is no electricity? And BTW, Einstein invented a version of this.

sadenly happend condensor servises Civilisation sadly* happened* condenser* services* Civilization* Before you go complaining about other people. Could you please work on yourself? I mean, if you can't act competent enough why don't you "go grab a mop and get hired in some cleaning service..." P.S. don't try to act smart when you can't even spell words correctly :/

...How crazy are you to invent something like this. Regular refrigerator and ac units are simple compared to this.

Not a single word was said about hydrogen role. Not said how sadenly "LOW pressure" happend in evaporator [so ammonia boils] even that one pipe before, in condensor the pressure was HIGH enough for ammonia to condensate... Why is every ignorant person is blatant enough to post spam on youtube? Seems that if you are incompetent, grab the mop and go and get hired in some cleaning servises... no, guy is trying to post scrap here... sad, sad, sad... what happend to our Civilisation?
