Analysis of HFC-134a-DMAC based compression-absorption heat pump for high temperature applications.
Author(s) : ARUN M. B., MAIYA M. P., SRINIVASA MURTHY S.
Summary
An analysis of a compression-absorption heat pump with single-stage solution circuit using HFC-134a-dimethyl acetamide (DMAC) is made. Effects of suction and discharge pressures, and generator and absorber temperatures on performance parameters such as circulation ratio, discharge temperature and heating coefficient of performance are studied. The performance is also compared with that of the conventional HFC-134a vapour compression heat pump and the operating domain diagram is generated for various average solution concentrations.
