METHOD FOR MAINTAINING AN OPTIMAL TEMPERATURE REGIME FOR A SOLAR MODULE AND A DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: agricultural infrastructure. ;SUBSTANCE: invention relates to solar technology and can be used for the electrification of agricultural infrastructure. The cooling of photovoltaic cells to the optimum temperature is carried out by an anti-gravity heat exchange device with a capillary body, the condenser part of which is immersed in the lower horizon of the soil to a depth that provides cooling of the coolant to the optimum temperature of the photovoltaic cells within 20-30°C, and the upper part of the heat exchange device with an evaporator is connected to the substrate of the solar module and the photovoltaic cells are cooled due to the transfer of heat by steam from the evaporation zone down to the condensation zone of the device, where the coolant is condensed due to the return of the latent heat of vaporization to the lower soil horizon, from where the coolant in liquid form through the capillary body rises up into the evaporator, the process of regeneration of the coolant repeats cyclically, while the parameters of the coolant are selected in such a way so that the boiling point coincides with the lower limit of the range of temperatures optimal for the operation of photovoltaic cells, and the depth of the filling of the condenser part of the heat exchanger is chosen in such a way that the temperature of the ground ensures the cooling of the heat carrier to the optimum temperature of the photovoltaic cells.;EFFECT: invention makes it possible to maintain the optimal operating temperature of photovoltaic cells and avoid distortion of electrical characteristics under the influence of extreme temperatures by cooling the photovoltaic receiver of the solar module by heat exchange between the frame (substrate) of the photovoltaic cell and the lower soil horizon due to the temperature difference across the heat exchange device with an evaporation-condensation cycle. ;2 cl, 1 dwg
