It seems to me that solar power and air conditioning are made for each other. As of now there are several different companies making smaller adsorption/absorption AC units, but they are overpriced compared to their electric driven counterparts giving limited return on investment. Here's what I've found:
LiBr units: expensive and mostly large units. (few residential applications.)
Silica Gel or other Adsorption: expensive and the desiccant takes up a lot of space. Also mostly larger units.
Ammonia: not in commercial use due to safety concerns.
There may be others, but these are all I could find that are thermal driven. Since a PV driven solar AC is just electrically driven I don't count it as a viable option until PV power is cheaper than grid power.
What is your take on solar powered AC? Is it doomed to failure until we have new technology that makes it affordable or are we just waiting for someone to build a cheap standardized unit? Is there anything I haven't mentioned?
