A few years back a Purdue University grad student came up with
a new AC unit based upon compression and expansion of air in
a chamber. Purdue is now looking into commercially vending the
unit.
The device featured no compressor! Problems were that you could
not regulate the temp of the air out. It was near freezing. They
were looking into heating the output. About one fourth the size
of a modern AC with no belts.
I believe it was going to be called a ROVAC.
I'll send on email to the ME dept at PU and see if they reply.
