Abstract
An experiment was carried out on the performance of water-resource heat pump water heater under various inlet water temperature of evaporating side.The results showed that the discharge pressure, discharge temperature and power input were increased with hot water temperature; and the heating power and COP were decreased with hot water temperature. The coefficient of the system was increased with inlet water temperature on the evaporator side. The heating power of the system was 22.83 kW, 25.95 kW, 27.31 kW, the power consumption of the system was 5.30 kW,5.58 kW,5.84 kW, and the coefficient of the system was 4.31, 4.65 and 5.64 on conditions of evaporator inlet water temperature of 12 ℃, 15 ℃ and 30 ℃, respectively.
