Solar PVT heat pump system integrated collector station

Technical Field

The utility model belongs to the technical field of comprehensive utilization of solar photovoltaic and thermal energy, and specifically relates to a solar PVT heat pump integrated heat collection station.

Background Art

With the widespread promotion and application of clean energy and the serious impact of excessive carbon emissions on the ecological environment, the utilization of solar energy has become a key development direction for researchers. Compared with other energy sources, solar energy is inexhaustible, and solar energy can be converted into photoelectric, photothermal and photochemical energy. There are also a series of development and application studies on solar energy storage devices. In this field, there are technical defects in single solar photovoltaic and photothermal technologies, resulting in low solar energy utilization. Many researchers have proposed comprehensive utilization schemes for photovoltaic and photothermal energy. For example, Wang Haoyu et al. proposed a heating system and use method based on multi-functional complementarity, Dong Suiju et al. proposed a solar photovoltaic waste heat combined with heat pump heating system and its working method, Cai Liang et al. proposed a dual storage hot water system based on solar energy and heat pump, and Wang Xinrong et al. proposed a solar thermal photovoltaic household microsystem for multi-story residential buildings. The above studies use PVT components or solar collectors to store the collected solar heat through PVT heat pump units or other types of heat pumps in the water collection tank for users to use. However, the installation locations of the heat-storing water-collecting tanks, photovoltaic inverter grid-connected equipment, and power supply devices are either exposed to the outside or are relatively scattered, which causes great trouble for the maintenance and management of the system.

Utility Model Content

In view of the above problems, the utility model proposes a solar PVT heat pump system integrated heat collection station, using clean renewable energy solar energy as the heat source of the system, combined with a heat collection tank and photovoltaic grid-connected equipment.

The heat collection station is an integrated device that realizes the solar thermal collection system, the photovoltaic grid-connected and the power distribution system, which protects the equipment from being corroded by the external air environment, reduces heat loss, shortens the installation period, and also facilitates the operation and maintenance management of the system.

The two interfaces of the PVT heat pump unit 200 are respectively connected to the circulating water pump group 2 and the heat collecting tank 1 through pipes to form a heat source side system; the heat collecting tank 1 and the user load side 100 are connected through pipes through an interface to form a user side system; the heat collecting tank 1 and the replenishing system side 400 are connected through pipes through an interface to form a circulating raw liquid replenishing system; the PVT component 300, the photovoltaic inverter 3, the photovoltaic grid-connected box 4, the power box 5 and the control box 6 are connected in sequence through cables.

The equipment in the heat collecting station controls the actuators through the control box 6, and the control box 6 is wirelessly connected with the circulating water pump group 2, the heat collecting tank 1 and the sensors on each control valve group.

Here we will give a brief overview of the operating process of the integrated solar collector station. A circulating water pump is used to send the water in the heat collector tank to the PVT heat pump unit for heating. When the temperature in the heat collector tank reaches the set temperature, the hot water is transported to the user-side system. When the liquid level sensor in the heat collector tank detects that the heat collector tank has reached a low liquid level, the valve on the supplementary system side is opened to replenish water. When the liquid level in the heat collector tank reaches the full level, the valve on the supplementary system side is closed, and the circulating heating process is implemented.
