Summary

A simulation study on the operating performance of a new type of solar-air source heat pump water heater (SAS-HPWH) hasbeen presented. The SAS-HPWH used a specially designed flat-plate heat collector/evaporator with spiral-finned tubes to obtainenergy from both solar irradiation and ambient air for hot water heating. Using the meteorological data in Nanjing, China, thesimulation results based on 150 L water heating capacity showed that such a SAS-HPWH can heat water up to 55°C efficiently under various weather conditions all year around. In this simulation study, the influences of solar radiation, ambient temperature and compressor capacity on the performance of the SAS-HPWH were analyzed. In order to improve the overall operating performance, the use of a variable-capacity compressor has been proposed. [Reprinted with permission from Elsevier. Copyright, 2005].
