Description
technical field [0001] The invention relates to a composite hot water system, in particular to a photovoltaic solar heat pump power generation hot water system with high conversion efficiency and low energy consumption. 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 increases the temperature of solar photovoltaic cells. As the temperature of the photovoltaic cell increases, the efficiency decreases instead. [0003] Solar heat pump is a special heat pump that uses solar energy as a low-level heat source. It can provide users with high-grade domestic hot water, and has attracted people's attention for its energy-saving, high-efficiency and many other advantages. Contents of the invention [0004] Purpose of t...
