A window air conditioner is both cheaper to run and quieter. My adventures
with Vortex tubes many years ago required hearing protection and that stupid
compressor running almost continuously.

I bought a 10k BTU window unit at an outlet store (condenser fins were
crushed, 20 minutes with a borrowed fin comb took care of that) and
installed it in my fully insulated 3 car garage. It does a great job of
keeping the area workable during Boise summers and barley makes a blip on
the electric bill.

work, but not sure of the efficiency. If you had water, or wind, power
running a compressor, you could have it for "free". Interesting.
