Water-cooled double-circulation photovoltaic photo-thermal integrated system

Abstract

The utility model relates to the technical field of photovoltaic heat dissipation, and provides a water-cooled double-circulation photovoltaic and photo-thermal integrated system which comprises a heat exchange assembly, a photovoltaic side soft water circulation system and a building side cold water circulation system. The photovoltaic side soft water circulating system comprises a first pipeline, a PV / T photovoltaic panel and a circulating pump; the first pipeline is sequentially communicated with the PV / T photovoltaic panel, the circulating pump and the heat exchange assembly to form a closed circulating loop; the PV / T photovoltaic panel comprises a photovoltaic panel surface layer and a heat conduction assembly arranged on the back surface of the photovoltaic panel surface layer, and the heat conduction assembly is in contact with the working medium in the first pipeline; the building side cold water circulation system comprises a second pipeline and a cold water pump; one end of the second pipeline is communicated with a tap water source and / or a building condensate water source, and the other end of the second pipeline is communicated with a domestic hot water pipe network. The device has the characteristics of less extra energy consumption, excellent cooling effect, difficulty in pipeline blockage and the like.
