Problems solved by technology

The heat transfer efficiency of this cold and hot medium is on the low side, which is the main reason for the low light energy utilization rate of existing solar water heaters. The existing solar water heaters require sufficient light time. The requirement for shorter pipelines is also based on this factor.

Abstract

The invention provides a photo-thermal photovoltaic combined intelligent efficient solar hot water supply station comprising a solar thermal collector, a heat preservation water tank, a water inlet valve, a water outlet valve, a water inlet pipe, a hot water outlet pipe, a hot water outlet valve, an exhaust valve, a water return pipe and a mixed flow pump. The water return pipe is arranged between the water return end of the heat preservation water tank and the water inlet end of the solar thermal collector. The mixed flow pump is arranged between the water outlet valve of the solar thermal collector and the heat preservation water tank. The mixed flow pump operates to drive water flow to conduct internal circulation, so that water flow is in dynamic contact with the inner wall of vacuum thermal collection pipes, and therefore solar energy absorbed by the vacuum thermal collection pipes can be transmitted to water flow more timely; in this way, the thermal conversion efficiency of the solar hot water supply station is greatly improved; meanwhile, power is supplied to the mixed flow pump through photovoltaic generation, cost is saved, the thermal utilization rate is increased, the work time is greatly shortened, and a powerful technological support is provided for wide application of the solar hot water supply station.

Description

Technical field: [0001] The invention relates to a solar hot water supply system, in particular to a photothermal photovoltaic composite intelligent high-efficiency solar hot water supply system capable of automatic forced heat exchange. Background technique: [0002] With the development of modern society, human beings are increasingly dependent on energy and resources, and we all know that the resources on the earth are limited, so seeking abundant, clean, cheap and most promising energy has become the first problem that people need to solve. Solar energy is a durable energy source that can be freely used, has no pollution, and has low energy density. It is the most abundant energy available to human beings, and it is also the cleanest, cheapest, and most promising energy source. For a long time, people have done a lot of work in exploring solar thermal utilization and achieved good results. Among them, the heat conversion technology of solar water heaters is undoubtedly ...
