The heat pump is a high-efficiency energy-saving device which makes full use of low-grade heat energy. Heat can be transferred spontaneously from a high temperature object to a low temperature object, but cannot proceed spontaneously in the opposite direction. The working principle of the heat pump is a mechanical device which forces heat to flow from a low-temperature object to a high-temperature object in a reverse circulation mode, and the heat pump can obtain larger heat supply amount only by consuming a small amount of reverse circulation net work, and can effectively utilize low-grade heat energy which is difficult to apply to achieve the purpose of energy conservation. The water source heat pump is one kind of heat pump, and the working principle of the water source heat pump technology is as follows: the low-temperature heat energy is transferred to the high-temperature position by inputting a small amount of high-grade energy (such as electric energy). The water body is respectively used as a heat source for heating by the heat pump in winter and a cold source for an air conditioner in summer, namely, the heat in the building is taken out in summer and released into the water body, and the heat can be efficiently taken away due to the low temperature of the water source so as to achieve the purpose of indoor refrigeration of the building in summer; in winter, heat energy is extracted from a water source through the water source heat pump unit 1 and is sent to a building for heating. In this embodiment, the PVT plate assembly 3 includes a photovoltaic plate and a heat exchange channel disposed on a lower surface of the photovoltaic plate, and the heat exchange channel is used for circulating a medium. The water source heat pump unit 1 uses a heat medium generated by the PVT plate assembly 3 as a heat source so as to supply heat.
