Investigation of solar greenhouses with transformable (adjustable) body depending on indoor and outdoor air temperature
Abstract
Abstract The article studies the thermal regimes of solar greenhouses for individual purposes, taking into account their design features. According to the results of the calculations, it was found that, according to the shape of the structure of solar greenhouses, for example, a rectangle with a triangular coating, with the same areas, but with different designs of single-slope and double-slope solar greenhouses with a total area of 42 m 2 , has a difference in heat load of 225 W. The thermal load in relation to the total percentage is 27% in single-slope and 37% in double-slope solar greenhouses. Depending on the outside temperature, to maintain the temperature inside the solar greenhouse, it is necessary to vary the heating height, that is, to reduce or increase the heating height inside the greenhouse. This ensures the minimization of energy consumption and optimal heating of the air inside the solar greenhouses.
