still thinking about "unglazed collector/regenerator performance for a solar
assisted open cycle absorption cooling system." by m. n. a. hawlader et al
in solar energy, vol. 50, pp 59-73, 1993. ("an ordinary black shingled roof
was used as a collector/regenerator for the evaporation of water to obtain a
strong solution of absorbent for use in the absorber... experimental results
[using a 36' x 36' roof] show a regeneration efficiency varying between 38
and 67%, and the corresponding cooling capacities ranged from 31 to 72 kw
(8.8 to 20 tons.)")
it might be better to cover the roof with polycarbonate so the lithium chloride
($4/lb from cyprus foot mineral) doesn't make the neighborhood too mellow...
