Abstract

The invention discloses a device for two-way cooling of a photovoltaic building by using a natural low-temperature heat source. The device comprises a plurality of photovoltaic assemblies, a cooling part, a low-temperature heat source part and a connecting pipeline system, wherein the photovoltaic assemblies are arranged at the roof through an assembly framework; the cooling part is positioned at the roof; the low-temperature heat source part is positioned underground; and the connecting pipeline system is used for mutually communicating the cooling part with the low-temperature heat source part. The cooling part comprises pit-shaped cooling holes formed below the photovoltaic assemblies; and cooling air of the low-temperature heat source part is transmitted to the pit-shaped cooling holes for cooling the photovoltaic assemblies by the connecting pipeline system and cooling the roof during flowing through the roof. According to the device disclosed by the invention, natural underground cold air is used as a low-temperature heat source and is used for gradually cooling the indoor of an inclined building and photovoltaic building integrated solar panels, and thus the temperature environment of the indoor is improved and the power generation efficiency of the solar panel is increased; and in addition, no energy source input is needed and the pollution to the environment is avoided. The device has stronger practicability, environment friendliness and economy and is especially worthy of being popularized in regions with great day-and-night temperature difference and plateau regions.

Description

technical field [0001] The invention relates to a BIPV building roof device, in particular to a device for two-way cooling of a photovoltaic building using a natural low-temperature heat source. Background technique [0002] The photovoltaic modules of BIPV must meet the performance requirements of photovoltaic modules and at the same time meet the relevant building safety performance requirements, so they need to have higher mechanical and thermal properties than ordinary components. Especially the heat-resistant temperature, in different locations, different floor heights, and different roof methods, all put forward strict requirements on its thermal performance. [0003] The physical indicators of photovoltaic panels and their related working characteristics show that when the operating temperature of photovoltaic cell components is high, the working efficiency decreases. As the temperature of the photovoltaic cell increases, the open circuit voltage decreases. In the ra...
