The performance of the instantaneous air-source heat pump water heater was studied,and the influence of double-pipe length on heat pump water heater performance was analyzed in this paper. The experimental results show that:double-pipe length has a certain impact on the system performance,such as heating capacity,energy efficiency ratio and other properties which this effect is increased with the double-pipe length deviation from the normal range;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.
