EXPERIMENTAL RESEARCH ON DYNAMIC PERFORMANCE OF AN AIR/WATER SOURCE HEAT PUMP WATER HEATER

ABSTRACT
In this paper, a combined air/water source heat pump water heater is presented. At ordinary time, the heater can be used for hot water heating in water-source mode to improve the energy efficiency. While in cold season, it gives priority to air-source mode for water heating to improve operational safety. Experiments were conducted to investigate the thermodynamic performance of the heater in each operation mode, and the experiment results were analyzed. The research indicated that its operation was reliable during the long-time running. This paper offers a promising energy-saving method in future.
