ABSTRACT:
A solar heat utilized air-conditioning system comprising: a solar heat collecting unit for producing warm water by heating a circulating heating medium water by solar heat obtained by collector plates disposed in parallel with each other; an absorption type refrigerating machine for producing cold water by provoking a refrigerating cycle, using the warm water produced by said solar heat collecting unit as the heat source for a generator; a main heat exchanger which indirectly heat-exchanges an intake fresh-air for a circulating cold or warm water in an air-conditioning unit disposed on the way of a fresh-air intake path to a space to be air-conditioned, thereby to produce cooling or heating air; an air-cooling and heating apparatus capable of selectively supplying the circulating cold or warm water to said main heat exchanger; and an auxiliary heat exchanger capable of selectively flowing either warm water produced by said solar heat collecting unit or cold water produced by said absorption type refrigerating machine, said main heat exchanger and said auxiliary heat exchanger being disposed in parallel with and adjacent to each other in said air-conditioning unit with said auxiliary heat exchanger disposed at the fresh-air intake side thereof.
