摘要
通过对空气源热泵热水器的性能进行实验研究,测试了水流量对热泵热水器性能的影响。实验结果表明:水流量对加热时间、能效比等性能有一定的影响,这种影响随着流量偏离正常值而加剧;设计适当的水流量,不但可以适当提高热泵热水器的能效比(COP),而且降低了冷凝器进出口水的温差值和排气压力。
The water mass flow on the performance of air - source heat pump water heater was discussed in this paper. The results show that water mass flow plays a certain role on the heating time, energy efficiency （COP） and other properties, which this effect is increased with the flow deviation from the normal range. The energy efficiency of heat pump water heater is improved by correct the water mass flow, in addition, discharge pressure can be reduced, the value of the condenser temperature difference between the import and export of water also can be reduced.
