Collerado Coolers: Getting Close to Solar Powered Air Conditioning
From Treehugger.com: We are intrigued by the idea of solar powered air conditioning; it is just so logical as you need it most when the sun is blazing. Right now the heavy-handed approach is to spend a lot of money on photovoltaics to run conventional units; there has to be a lower cost, more efficient way.
The approach of warm weather (and a nudge by LEED Pro) has reminded us of Coolerado Coolers, a low energy air conditioning unit that delivers up to 5 tons of cooling while drawing only 1200 watts, a power load that can easily be handled by a solar installation. It is an evaporative cooler like the desert coolers we have shown before, but unlike most desert coolers, the cool moist air is put through an air-to-air heat exchanger so that the air supplied to the space is cool and dry, which is far more effective at keeping you cool. 848
