The solar energy heat pump system maximizes the energy saving advantage of solar energy and heat pump, and it is of great significance to alleviate the current energy consumption problem. In recent years, this technology has been widely applied to the indoor heating system. A kind of small solar heat pump heating system was designed based on the combination of the solar energy and heat pump technology. Aiming at the climate conditions in Yinchuan, the experimental study on solar energy heat pump heating system was conducted, and the influences of the water evaporation end on the heat absorption, heat capacity, the compressor suck-exhaust pressure and the compressor cop were analyzed . Research results show that the small solar heat pump heating system is feasible, the terminal temperature can meet the heating requirement, and the energy saving and energy efficient utilization effect is obvious.
