A design for a closed, diurnal, intermittent absorption chiller for passive solar air-conditioning using liquid sorbents has been constructed and tested. LiBr-H/sub 2/O will not work with this design because of its low vapor pressure at the temperature available. The approach has possibilities using the 2 LiBr-ZrBr-CH/sub 3/OH or H/sub 2/O-NH/sub 3/ sorbent refrigerant pairs. The use of H/sub 2/O-NH/sub 3/ appears to be the better candidate because of the lower solution viscosity and less cycle weight, through tank volumes and collector requirements are similar. Further study of other refrigerant pairs such as S-Thiocyanate-ammonia is indicated, however, the difficulties encountered in construction and low potential coefficient of performance, and thus large collection area needed, makes commercialization of such a system doubtful in the foreseeable future.
