Abstract :
The prototype of dual-source heat pump water heater using air and water is assembled, and experimental research of performance is tested using air as heat source, respectively the ambient temperature is 7°C and 20°C; water temperature of the prototype using water as heat source is respectively 15°C, 30°C. the results showed that the dual-source heat pump utilizes water source in the summer, utilizes air source during intermediate seasons, running stable and energy-saving effect is obvious, Coefficient of performance could reach up to 5.58 with the minimal value approximately 3.21.
