Problems solved by technology
At the same time, after the PVT system collects heat, the temperature of the solar cell backboard is too high, resulting in a decrease in the photovoltaic power generation efficiency of the panel, which affects the work of the photovoltaic power generation system. The parameters of the hot water provided cannot be directly used for heating. Sufficient time, there is a problem that the light-to-heat conversion cannot be guaranteed around the clock, resulting in the inability to continuously supply hot water

Description
technical field [0001] The invention relates to the technical field of photovoltaic photothermal and heat pump equipment, in particular to a PVT photoelectric storage heat type water source heat pump system and an operating method. Background technique [0002] The working principle of the water source heat pump is based on the reverse Carnot cycle principle. It is driven by electric energy and absorbs low-grade heat energy such as groundwater, lake water, river water, urban sewage, seawater, industrial waste water, etc. through refrigerant, and upgrades it to usable high-grade heat energy for heating water. equipment. [0003] Water source heat pump generally consists of compressor, expansion valve, filter, liquid storage tank, condenser, evaporator and other parts. The low-temperature and low-pressure gaseous refrigerant is compressed into a high-pressure and high-temperature gaseous state by the compressor. The high-temperature and high-pressure gaseous refrigerant under...
