摘　　要：某农村住宅安装了空气源热泵辅助太阳能供暖系统。针对2014—2015年度供暖季系统的制热量、耗电量等性能参数进行了测试。结果表明,室内日平均温度为19.6℃,热泵机组日平均COP为4.29,供暖系统日均综合能效比为3.52,日均太阳能贡献率为4.87%。该供暖系统的热泵机组具有较好的运行性能,但太阳能贡献率偏低,整个供暖系统仍有进一步优化的空间。A rural residence adopts air-source heat pump assisted solar heating system. Tests the heating capacity, energy consumption and other performance parameters of the system in the heating season of 2014 to 2015. The results show that the indoor mean daily temperature is 19.6 ℃, the average COP of air-source heat pump is 4.29, mean daily comprehensive energy efficaiency ratio of heating system is about 3.52, and the mean daily solar energy contribution rate is 4.87%. The heat pump unit of the heating system has good operating performance in winter, but the solar energy contribution rate is low, the whole heating system still needs further optimization.
