Influence of the heat accumulator’s storing capacity to increase the efficiency of helogreenhouses

Abstract

The theoretical study carried out shows that the main geometric and energy characteristics of solar greenhouses are the coefficients of enclosure and heat accumulation. The influx of solar radiation depends little on the angle of incidence of the rays on transparent surfaces, and mainly depends on the surface area of the transparent fence. The amount of heat accumulated in a heat accumulator is determined by its heat-storing efficiency: material, ability to absorb solar radiation, volume, location. With sufficient mass values of the heat-storing elements, all or almost all of the solar energy captured by the heat-storing elements is usefully used, overheating in the greenhouse is eliminated, and daily fluctuations in air temperature in the greenhouse are smoothed out.
