摘　　要：本文介绍了一种空气源热泵辅助加热的太阳能热水系统，测试分析了该系统实际运行工况下的热力性能。测试结果表明，通过合理的部件匹配，昆明地区气候条件下空气源热泵辅助加热的太阳能热水系统太阳能热水子系统的日平均热效率约为38％-50％，太阳能保证率可达81％；空气源热泵机组的供热系数在最冷月仍可达2．5～3．3。In this paper, a solar energy water heater in conjunction with air-source heat pump （SEWH-ASHP） was designed. The performance of the SEWH-ASHP under the climate condition of Kunming was tested and analyzed. The results indicated that the daily efficiency of the solar energy water heating subsystem changed from 38 % to 50 %, and the solar collectors could provide about 81% heat loads during the whole year. In addition, the COP of the air-source heat pump unit would reach at 2.5 - 3.3 during the coldest month.
