Assessment of the thermal accumulating solar stations efficiency
Abstract
The impact of heat-generating facilities on the environmental condition of adjacent territories is assessed. The possibility of using solar energy to reduce the anthropogenic impact on the environment is substantiated. It is proposed to create cascade solar installations to provide hot water supply to residential buildings and industrial facilities. A scheme of a solar power station with a seasonal solar energy accumulator based on depleted quarries to ensure year-round supply of hot water is proposed. A mathematical model is proposed for calculating the efficiency of solar collectors with transparent and rear insulation, which make up the third stage of a three-stage solar DHW system. The relative error of mathematical models in comparison with test data is presented. The average monthly efficiency of the third cascade of calculated mathematical models for climatic conditions of the Crimean peninsula is given. A refined algorithm for calculating the efficiency of solar collectors of the third stage has been developed.
