A comprehensive survey of the current state of the absorption cooling technology has been conducted. This survey discusses the basic and applied absorption cooling/heating technology, analyses the current state of the art including the discussion of limitations and possible solutions, identifies areas where promising developments are indicated, lists the current products and activities of the absorption industry, and presents the current RD and D efforts of the U.S. government. The main subjects covered in the survey are as follows: Principles of absorption cooling technology (NH/sub 3/-H/sub 2/O cycle and H/sub 2/O-LiBr Cycle), Adaptation of absorption cooling technology for solar cooling applications, Thermal performance of absorption cooling units, Comparison of NH/sub 3/-H/sub 2/O absorption with H/sub 2/O-LiBr absorption, Commercially available solar absorption units, General trends of the absorption cooling industry toward solar application, Absorption cooling system performance in actual installations, Limitations of absorption cooling technology, Solar-powered absorption heat pumps, and U.S. ERDA activities relating to solar absorption cooling. The treatment of the subjects is intended to be basic and comprehensive in order that the general readers may understand the current aspects of absorption technology in solar cooling applications. 36 references.
