摘　　要：介绍了小型太阳能/空气双热源热泵系统的原理及运行模式,以北京某乡村住宅为例,结合建筑热负荷及当地的气象参数,确定了该系统的模式,引入最佳切换温度及供热季节性能系数HSPF,得到最佳切换温度为-1~0℃,对应的HSPF值为2.49左右。与其他系统相比较,该系统具有明显的经济性和节能性。The principle and operation mode of the small dual-source solar assisted air heat pump is introduced in this paper. Taking a country house in Beijing as an example, the model of the system is established according to the heat load of the building and the local meteorological parameters. By introducing the best switching temperature and heating season performance coefficient HSPF, the optimal switching temperature is-1~0 ℃, and the corresponding HSPF value is about 2.49. Compared with other systems, the system has obvious economic and energy efficiency.
