Compression-absorption heat pumps

Paper in proceeding, 1990

This paper describes the recent work worldwide on compression-absorption heat pumps, sometimes called the compression heat pump with solution loop. Most workers have concentrated on the use of NH3/N20 as working pair, a choice justified both in terms of performance and environment. Work has also tended to concentrate on higher temperature applications, an area for which the pair NH3/H20 is well suited., Although several large scale experimental plants have been built and operated there is still considerable work to be done before such systems can be considered practical.
