摘　　要：介绍以空气源热泵为辅助热源的主被动结合式太阳能采暖系统,利用DeST软件模拟计算太阳房的采暖负荷,确定主动部分及辅助热源的设备选型,以验证太阳房的节能效果;对太阳能采暖系统在测试期间的室温结果、运行情况进行分析,计算系统在测试期间产生的能耗。结果显示:被动式阳光房的节能效果显著,被动部分的供热量为121.5 kWh,主动部分的供热量为102.7 kWh,辅助热源的供热量为387.7 kWh,太阳能的贡献率为36.7%,太阳房采暖负荷为43.2 W/m^(2)。The paper introduces a kind of active and passive solar heating system with air source heat pump as auxiliary heat source. The heating load of the solar house is simulated by DeST, and the equipment selection of the active part and auxiliary heat source is determined to verify the energy-saving effect of the solar house. The room temperature results and operation of the system during the test are analyzed, and the energy consumption of the system during the test is calculated. The result show that the energy-saving effect of passive solar heating is remarkable, the heating volume of the passive part is 121.5 k Wh, the heating volume of the active part is 102.7 kWh, the heating volume of the auxiliary heat source is 387.7 k Wh, the contribution rate of solar energy is 36.7%, and the heating load of the solar house is 43.2 W/m^(2).
