Abstract

Experimental study was performed on a novel direct-expansion solar-air source heat pump system for domestic water heating, in which a collector/evaporator using spiral-finned tubes could absorb heat from both solar radiation and ambient air. The prototype was tested for heating water from ambient temperature to 55°C on both sunny days and overcast days. Furthermore, the effects of solar radiation, ambient air temperature and relative humidity on the system's performance were analyzed.
