Standard propane has some contaminates in it.
Highly refined propane is used as a refrigerant called R-390.
Can be used to replace R-12, R-22, R-134.
I use a form of it in my 73 Ford truck in place of R-12.
Does not work as well as R-12.
The evaporator and condenser have to be sized correctly to get max
efficiency.
Running compressors in reverse are normally not as efficient as the
mode they were designed for..
