摘要：

An aluminum roll-bond panel with a photovoltaic module on the surface was developed recently for use as an evaporator of a heat pump for residential hot water supply and room heating [Proceedings of the JSES/JWEA Joint Conference, Okinawa, pp. 305-308 (in Japanese)]. In the present study, the panel was modified to reduce the large pressure loss of the refrigerant flow at the evaporator Total area of the panels was 1.9 m(2) and the rated capacity of the compressor was 250 W. A collector efficiency factor of 0.9 was obtained for the evaporator. The effect of the location of the feeler bulb on performance of the heat. pump was also examined.
