I think I'll try to build my own hybrid A/C in the future, but with a conventional refrigeration loop using ES-22a.
Not to rain on anyone's parade, but my rather ordinary, inexpensive Frigidaire window A/C has a COP of 10.5, or a EER of 36 and probably a SEER around 40. I hope he didn't worsen the COP by trying to evaporatively cool the condenser.
