I think you are confusing using propane for the power source vs. versus using propane as the refrigerant. Propane does work as a refrigerant as it is easy to compress into a liquid and then let it vaporize into a gas. It is the "latent" heat of vaporization that makes mechanical refrigeration practical.

He said that originally AC units were propane then went to R12 and that didn't work too well for the environment and then 134a, which also didn't work well on conversions, so now they're about ready to start using propane again.
