The OP is not too far off. I once had a house that had a natural gas powered AC. It was actually NG and electricity. It used the NG to boil/heat up an amonnia solution that cooled water. Then the cold water was circulated into the house using an electric pump. It was noisey but it worked. I am not sure how much money I was saving, that was over 20 years ago. When it broke down we had to replace it with a normal unit, they did not make the NG unit any longer.
The unit was not that much bigger than a normal AC. It did have a much larger "burner" than used in a fridge. I expected that it used a fair amount of NG, but it was cheap at that time in Southern California.
The idea may be of some use if you are trying to limit your use of electricity and propane is not too expensive. But it may be expensive.

"Heating to Chill" exists.
Many large complex building use the technology.
The machine is called a Lithium Bromide Liquid Absorbion Chiller.
Lots of heat (a boiler), steam to the chiller, liquid bromide is heated then chilled by a water cooling tower, bromide expands and then is run through an evaporator.
Lithium bromide is touchy. A bit too much heat and is solidifies and clogs up the chiller.

Did we get lost in the woods.
"Propane Powered A/C" ~ Okay, transfer heat. Do we not need AC for air movement? ~~ I read it on the internet. Trucks are soon to have the option of a Chinese A/C and AC all from one small engine. No noisy big and expensive diesel engine running just to supply cooling and AC. Could it come also for the RV?

Hi Ya'll,
Sorry to wind up and let ya'll go. I got a little busy.
I was meaning using battery to run the circulation fan, but using the propane to do the cooling. Seems it can be done, but doesn't seem to be feasible.
That sounds like the case to ya'll?
