Abstract

The performance of the instantaneous air-source heat pump water heaters which is made of the different double pipe heat exchangers respectively was studied, the influence of double-pipe inner wall thickness on the heat transfer area, the water flow velocity, the heat transfer coefficient, and the water system resistance of the double pipe heat exchanger was analyzed, and the influence of double-pipe inner wall thickness on heat pump water heater performance was studied in this paper. The experimental results show that: the energy efficiency of heat pump water heater is improved by the appropriate design of double pipe length, in addition, the heat capacity can be increased, and power consumption can be reduced.
