摘　　要：本文对直热式空气源热泵热水器的性能进行试验研究,分析了套管长度对热泵热水器性能的影响。实验结果表明:套管长度对制热量、能效比等性能有一定的影响;设计适当的套管长度,不但可以适当提高热泵热水器的能效比,而且增加了制热量,降低了耗电量。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.
