The working principle of the heat pump type hot water unit in the embodiment is as follows:
when the refrigerant flows into the first evaporator 22 and the second evaporator 7, it is converted from a low-pressure liquid state into a low-pressure gaseous state, and absorbs heat from the outside. Then, the refrigerant enters the compression pump 5 and is compressed into a high-pressure gas state, and after entering the condenser 32, the refrigerant is converted from the high-pressure gas state into a high-pressure liquid state and gives out heat to the second heat exchange water tank 31, so that the water in the second heat exchange water tank 31 is heated. After the high-pressure liquid refrigerant enters the gas-liquid separator 9 and the gas refrigerant therein is separated, the high-pressure liquid refrigerant enters the expansion valve 6 to be converted into a low-pressure liquid refrigerant and flows back to the first evaporator 22 and the second evaporator 7, and a cycle is completed.
The photovoltaic device can heat the water in the first heat storage water tank 1 by supplying power to the heating unit 11 in the daytime, and stores the heat energy generated by the photovoltaic device in this way, and because the temperature of the water in the first heat storage water tank 1 is higher, the heat energy absorbed by the first evaporator 22 is more, the overall operating power of the heat pump type water heater unit can be reduced, and the energy-saving effect is achieved.
