- An absorption refrigerator used in an RV operates differently than the typical household version, it actually draws heat out of the unit! This video provides an overview with graphic animation of the process.

beginning is tarded, regular elec fridges, AC units etc all absorb heat and relocate it to another space. The fact that a mechanical pump is not being used is another matter, it is still the Carnot cycle applied.
All captialists are retarded. The job isnt to enlighten you but keep you in the dark with confusion
Mook Faru who said anything about capitalists? But yeah, probably

"Cold" is the absence of heat, I believe, is a bit more than just a theory.
Cold is just like darkness which comes with absence of light. Coldness comes with absence of heat.
Nope it is a Theory, Most people confuse Hypothesis with Theory.
I have an ammonia refrigerator in my RV. The freezer will cool down to -10, the refrigerator section cools down quite well. This is a Norcold manufactured in 1987, so there is potential for longevity. I also installed a small condenser fan, a common ball-bearing computer fan found online.
I was visiting an old timer at his cabin once and noticed a buck rogers looking device hanging out of ancient icebox and asked what it was. It was a Crosley IcyBall. It was over 50 years at the time and it still worked.
Where can I get one to buoy
Hi, can you please tell me what flame temperature is best for the boiler I'm restoring one of these refrigerators and I can't seem to find anything about flame and flame temperature
Umm it is not called an absorption fridge because it absorbs heat! All fridges and ac dose absorb heat! They all draw heat a way from one side and dump it on the other. They all heat pumps!
"The water recombines with the ammonia at the far end of its voyage" AKA The water re ABSORBS the ammonia. Hence its called ABSORPTION REFRIGERATION
Just amazing 👏
Sodium chromate is listed but never explained in the process. Also, after the evaporation in the freezer, the video says ammonia separates and goes up through the secondary radiator. I think the hydrogen does that instead, as the water absorbs the ammonia, leaving only hydrogen gas.
Maybe it increase or decreases the boiling point of water?
The best video I've found so far.
Wait till you discover pornhub
sweet and simple !!!!!
So, Jesus miracles the heat out of the fridge and into the ammonia?
Kinda like old Arkansas chiller
I just wonder if one could hook this up to their wood burning stove? Instead of the gas. Combine that with using the heat to create electricity. We could heat, cool and give our houses electricity.
this works with any source heating system I think 🤔
In theory it should work..
Indeed... but the big utilities won't go for that. ;) Not in their favour you see...
If they haven't already, they will lobby the GOV to mandate that all homes MUST be grid tied. Canada is pretty much that way. Need mains to get an occupancy permit. Once you have that permit, nothing stopping you from dropping the mains line from your home. (Just means its another several thousand dollar tax on a new home, and that they don't give a hoot about you remaining grid tied. Gimme gimme gimme.)
80+ year old technology! I'm sitting here drinking ice water from my Norcold fridge watching this youtube video on my cell phone (technology that was invented in WWII by Hedy Lamar). Nothing is new.
What is the boiling temperature of the boiler, and the pressure?
So these things never fail? 🤔🤔
So I can’t make this at home? 😢
Excellent video. Got to the point quickly and effectively without all the extra unneeded rambling.
Witchcraft
Could you use the hot area under solar panels as a boiler?
Deppends on a few things, but things of that nature can be done. One issue is that it obviously only works for a little while. I feel a direction you would rather go at that point is a Sterling engine, though there have been issues with that so far. Not "this will never work practically" issues, just it does not work currently issues. We need to work on the process more.
Oh wait, you mean RV solar pannels. Sorry, my mind was on bigger house solar pannels for some reason. Not convinced you would get enough heat there. May be able to set up an economizer from that heat though.
Thanks for uploading this useful video. ⭐⭐⭐⭐⭐
couldn't they use other refrigerants? or any substances in general? Normally the compressor phase changes the refrigerant into a gas, there is too much inertia, so when the condenser dumps the excessive heat, the phase change doesn't have enough time to absorb heat, in the condenser, the refrigerant spends more time, and can phase change and absorb all the heat. So you could probably just remove the compressor from a fridge and put a propane torch to the line and it will do the same thing. I just don't understand why we got this special refrigerant here.
ammonia is a refrigerant.
Ammonia has an affinity for water and hydrogen lowers ammonia's boiling point under the specific pressure the fridge uses but gets kicked out of gaseous mixture when the water re-absorbs the ammonia. It operates on a few little chemistry and physics tricks that Albert Einstein and Leo Silard worked out.
The design has changed slightly but the principles remain the same.
Dude! We definitely owe you a beer for such an excellent explanation! I was a physics major and always appreciate someone who can explain and educate as well as you! Best of luck and carry on!!!
what school was that? this video is so inaccurate and wrong that I'd say it detrimental to have it out here.
1:10 why does the water magically return while the amonia travels on?!
i guess water condenses at a different temp to ammonia, returning to a liquid and flowing back while the ammonia gas separates and continues on to condense later
@@briangillick your "guess" is absolutely correct
The boiler works like a coffee percolator except instead of stram gaseous ammonia is produced. As the ammonia turns to gas, the bouyant ammonia, bubbles up the tube raising a column of water solution up the boiler tube. The boiler shown in the diagram is not typical of most rv refrigerators.
Is it more or less efficient than electric?
Way less efficient than electric. Uses almost three times more energy than an electric refrigerator.
You don’t understand this very well. Should’ve done more research before putting this video together. There is no polite way to say this. Sorry.
Sorry, maar deze man maakt grove fouten in zijn uitleg. Een compressor is een "gaspomp", er is geen vloeistof bij de compressor. Het hete gas wordt aan de bovenkant de condensor in geperst en hier condenseert het gas door de hoge druk en afkoeling. De warmte energie van de compressor en de opgenomen warmte in de verdamper wordt hier afgescheiden aan de buitenlucht. De vloeistof wordt hierna opnieuw ingespoten in de verdamper.
You are mistaken. You describe a conventional heat pump, not a single-pressure absorption refrigeration system used in recreational vehicles. The latter is what this video is about.
Wrong household refrigerators, hell even air conditioner, units, all work with the same theory of removing heat and displacing it into the coils in the back similarly, a heat pump removes heat from the outside, cold air and releases it in the building
Nope, not all work with the same theory. My great uncle, born in the late 1800's, had a kerosene fridge on his farm, and this tech was what worked without any electricity. It's significantly less efficient than modern refrigeration, but still useful in certain applications, like recreational vehicles.
This is just.. wrong. lol
Why
@@Ryskyguy Much of it is right, but the last part of the video, where he describes ammonia again becoming a gas (@1:55) is not correct -- that step of the process is where the hydrogen separates, travelling up in the diagram, and joining the cooled ammonia at the top left. Unless I am way off, this is where partial pressure helps the ammonia evaporate in the freezer compartment.
11 year old vid?...meh..
This is witch craft i just know it
No, it's engineer craft.
Someone please explain, if every process in the loop is adding heat, where does the heat go?
This wasn't explained the best. The heat is removed from the ammonia within the condenser.
@@AnUnapologeticApologistAnd it absorbs heat from the hydrogen in the freezer (which is extremely buoyant) and evaporates rapidly, drawing the thermal energy out.
To be cold, you need to be much hotter than your surrounding so you can transfer your heat to that surrounding and becoming cold yourself. It's like how you feel when suddenly coming inside colder building in hot sunny day.
This was what happened to Ammonia, it got heated by boiler and then it cold down when moving thru the first coil.
And vise versa, when Ammonia cold down, the 'surrounding air' inside the freezer which was much 'hotter' will transfer it's 'heat' to much colder Ammonia which then pumped to chiller section that transferred another group of 'heat' to 'slightly warmer' Ammonia.
Then the cycle repeat again.
Edit: The heat is everywhere in the system so it always pumped out when it present inside. In today's refrigerator, the pump will stop when it pumped enough heat to outside and will continue again when there's another heat inside based on their predetermined temperature setting.
