Abstract

The invention relates to a phase change heat storage solar air source dual-heat-source heat pump hot water power generation system. The heat pump hot water power generation system comprises a refrigerant circulation system, a water source heating system and a power generation system body. A photovoltaic panel and a heat collection evaporator are combined together, the heat of the photovoltaic panel is absorbed through phase change heat storage materials, and a refrigerant continuously and stably absorbs the heat of the solar photovoltaic panel in the heat collection evaporator to be evaporated. On one hand, the effect of cooling the photovoltaic panel is achieved, the photoelectric conversion efficiency of the photovoltaic panel is improved, and the photoelectric panel stably outputs electric energy. On the other hand, the effect of collecting the heat of the photovoltaic panel is achieved. Solar energy absorbed by the heat collection evaporator and air heat energy absorbed by an air cooling type evaporator exchange energy with cold water in a water cooling type condenser through a heat pump system, hot water is produced, and heat energy is effectively utilized. Accordingly, the energy quality is improved, energy is effectively utilized and saved, and the phase change heat storage solar air source dual-heat-source heat pump hot water power generation system has the advantages of being stable, convenient to use and the like.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a phase change heat storage solar air source dual heat source heat pump hot water power generation system. Background technique [0002] Solar photovoltaic power generation is a form of power generation that has developed rapidly in recent years. However, most of the solar radiation energy is not converted into electrical energy, but converted into thermal energy or radiated in the form of electromagnetic waves, which causes the temperature of the solar photovoltaic panel to rise. Photovoltaic cells (or solar cells) are very sensitive to temperature. It has been determined that at an operating temperature of 64°C, the efficiency of crystalline silicon solar cells drops by 69% compared to the efficiency measured under standard test conditions (25°C). [0003] Since an increase in temperature always leads to a decrease in photovoltaic conversion efficiency, it is necessary t...
