how much amp load ?????????

@KompulsaOfficial Continued: No one ever uses that method to cool their room, they use a fan to blow the cooled air through ice on themselves, which will of course work, but the room is being heated by the refrigerator in the process, but room cooling does not work that way.

@omegapoint777 First of all: Was the redneck ice cooler being used in the kitchen where the refrigerator was? If so, it is not going to work. The refrigerator generates mostly heat. It is 40% efficient and the other 60% of the electricity consumed turns into plenty of heat. In many cases cooling capacity is 3,000 BTU and it outputs more than 6,000 BTU of heat, and look up the Carnot efficiency limit. There is another problem with what you are saying. COntinued...

propane is a direct replacement for r12, hope that helps in future projects

@Informatively what? its a 120 volt compressor dude
-
@clborg88 Perhaps, but they will be very hot while doing so.

what does the condensor do??

@KSCPERFECT The condenser removes heat from the high pressure gaseous refrigerant, condensing it into a high pressure liquid.

so how would you make a heat pump? think about using a heat pump to extract the last btu's from rocket mass heater so that the air really drops down with heavy cold air.

@josephdupont All refrigeration systems are technically heat pumps. It's just that typically the hot side (condenser) is mounted near the compressor, so it's hard to use the heat produced.
Essentially, if you reversed the suction and discharge of the compressor, the heat pump will be reversed.

How did you evacuate it?

@bamaslamma1003 I used an air conditioner compressor. Certainly not a perfect vacuum, but good enough for a short run like this.
