Technical field

The invention relates to a solar photovoltaic panel and an air energy heat collecting panel, in particular to a multifunctional composite photovoltaic panel combining the solar photovoltaic panel and the air energy heat collecting panel.

Background of the invention

Solar photovoltaic and air energy heat pumps are clean energy which is often used by people, and people find that users need solar photovoltaic for power generation and air energy heat pumps for heating in practical application. The solar photovoltaic panel can generate heat under the sunlight and the efficiency is reduced, and the evaporator of the air energy heat pump needs to absorb heat, so that the heat generated by the photovoltaic panel is beneficial to both the photovoltaic panel and the air energy heat pump if the heat can be absorbed by the air energy heat pump.

Summary of the invention

The temperature of the solar photovoltaic panel can be gradually increased to be very high after the solar photovoltaic panel is irradiated by sunlight, too high temperature has influence on the efficiency of the photovoltaic panel, only natural wind energy is used for reducing the temperature of the photovoltaic panel, other effective methods for reducing the temperature of the photovoltaic panel are not available, if the wind of a fan for installing the fan on the photovoltaic panel is used for reducing the temperature of the photovoltaic panel, a good cooling effect is achieved, the problem is that the fan consumes electric energy during operation, and the heat of the photovoltaic panel is wasted. The heat collecting plate of the air energy heat pump is used for absorbing the heat of sunlight, and if the heat on the photovoltaic plate is transferred to the heat collecting plate through heat conduction, the heat on the photovoltaic plate can be utilized if the heat on the photovoltaic plate is absorbed by the heat collecting plate. Therefore, the photovoltaic panel and the heat collecting panel are overlapped together, a gap which is not more than 1cm is reserved between the photovoltaic panel and the heat collecting panel, a plurality of holes are formed in one end of the heat collecting panel, a plurality of small axial flow fans are installed on the holes, the installation position of each axial flow fan is perpendicular to the surface of the heat collecting panel, a plurality of small holes are also formed in the side face, farthest from the fans, of the other end of the heat collecting panel to serve as air outlets, air of the fans can be easily blown out from a gap between the two panels, and therefore the photovoltaic panel can reduce the temperature and the heat collecting panel can absorb heat. The photovoltaic panel faces the sun, the heat collecting panel is arranged behind the photovoltaic panel as shown in fig. 1, the photovoltaic panel can work under better efficiency due to the cooling effect of the fan, the evaporator (namely the heat collecting panel) of the air energy heat pump can well absorb heat energy in the air in the flowing air, the air blown out by the fan contains high-grade heat on the photovoltaic panel besides low-grade heat in the surrounding air, and therefore the heat collecting panel also works under a high-efficiency environment. The photovoltaic panel and the heat collecting panel are respectively operated in two independent systems, the two systems are respectively a photovoltaic power generation system and an air energy heat pump system, the photovoltaic panel is one of main components of the photovoltaic power generation system, the heat collecting panel is one of main components of the solar energy air energy heat pump system, the photovoltaic panel and the heat collecting panel are integrated together, but the photovoltaic panel and the heat collecting panel respectively serve in the respective systems, and the photovoltaic panel and the heat collecting panel are mutually utilized to make up for deficiencies and exert advantages.

The multifunctional photovoltaic panel compounded by the photovoltaic panel and the heat collecting plate is composed of a photovoltaic panel for solar power generation and a heat collecting plate for an air energy heat pump, and is characterized in that the photovoltaic panel and the heat collecting plate are overlapped together, and a gap is reserved between the photovoltaic panel and the heat collecting plate. The solar energy heat collection system has the advantages that three sides defined by the photovoltaic panel and the heat collection panel are closed, one side is an open air outlet, a plurality of holes are formed in one end of the heat collection panel, a plurality of axial flow fans are mounted on the holes, as shown in figure 2, wind energy in a gap between the photovoltaic panel and the heat collection panel smoothly passes through the holes as shown in figure 3, the air outlet is reserved at the position farthest away from the fans, the mode has the advantages that the heat collection panel can obtain heat of the photovoltaic panel and heat in air within 24 hours, and the efficiency of the whole system can be higher when the sun exists.

Detailed description of the preferred embodiments

The invention is further explained by combining the attached drawings and the embodiment, the photovoltaic panel and the heat collecting panel are buckled together, the distance between the photovoltaic panel and the heat collecting panel is about 10mm, three side surfaces of the two panels are closed, a plurality of small axial flow fans are equidistantly installed on one side of the photovoltaic panel or the heat collecting panel, and the side surface on the opposite side is an air outlet. A plurality of multifunctional plates compounded by photovoltaic plates and heat collecting plates are installed into a power generation system according to the photovoltaic plates, and then the heat collecting plates on the back sides are connected into an air energy heat pump system, so that one multifunctional plate works in two systems of photovoltaic power generation and the air energy heat pump respectively, waste heat generated by the photovoltaic plates is utilized by the air energy heat pump, the efficiency of the photovoltaic plates is improved, and the efficiency of the air energy heat pump is improved.
