"and, as we  know, AIR is a rather poor refrigerant"

No, it works OK!  Remember the ROVAC system that was supposed to 
revolutionize automotive AC systems?  It worked alright but they couldn't 
solve the noise problem with the compressor.  If they can ever make a quiet 
air compressor we may yet see air as an automotive AC refrigerant.
