SolCool scam or not? [RE-wrenches]

[Joel Davidson]

<x-flowed>

In the 1980s Wm. Lamb Company made a PV powered swamp cooler that was 
attached in front of the condenser of a conventional air conditioner. The 
cooler uses a 24 VDC Pitman motor direct powered by 2 each Arco 30-watt 
30-cell modules and also required water plumbed to it. Within 2 years, scale 
built up in the cooler and the painted sheet metal body rusted. The 
additional moisture on the air conditioner caused it to rust. The principle 
underlying direct evaporative (adiabatic saturation) cooling is the 
conversion of sensible to latent heat. Nonsaturated (low humidity) air is 
cooled by exposure to free and colder water, both thermally isolated from 
the other influences. Swamp coolers will work in Athens Greece, not Athens 
Georgia.

The Second Edition of Evaporative Air Conditioning Handbook by Dr. John R. 
Watt P.E. copyright 1986 had 450 pages of more than I ever wanted to know 
about the subject.

Do any wrenches or your customers use a swamp cooler?
