Problems solved by technology
However, since the air source heat pump uses air as the heat source in winter, the evaporation temperature will also decrease as the outdoor temperature decreases, and frost will form on the surface of the evaporator, which is extremely unfavorable to the heat pump.
With the formation of the frost layer, the heat transfer resistance of the evaporator increases, the evaporation temperature decreases, and the performance of the unit decreases

Description
technical field [0001] The invention relates to the technical field of solar energy recovery and utilization, and more specifically relates to a novel heat pump system for comprehensive utilization of photoelectricity, light and heat. Background technique [0002] At present, solar energy utilization mainly includes solar photovoltaic power generation and solar thermal utilization. In recent years, with the improvement of solar energy conversion efficiency, solar photovoltaic and photothermal utilization has developed rapidly. At the same time, due to the uneven distribution of solar energy resources, the cost of solar energy utilization equipment is high, and the efficiency of traditional solar photovoltaic power generation is low, which is not conducive to market promotion. [0003] The solar heat pump uses the waste heat generated by the solar panels in the process of power generation as the low-temperature heat source of the heat pump. In this process, the flowing worki...
