A friend of mine is working on a hybrid A/C that uses evaporative cooling to cool the condenser of a normal A/C. The prototype gets a SEER rating in the low 30s. It uses distilled water as the refrigerant. Main problem is that the "turbocompressor" (basically a modified turbocharger driven by a switched reluctance motor) is not a mass produced part.

I think I'll try to build my own hybrid A/C in the future, but with a conventional refrigeration loop using ES-22a.
