Use of heat accumulators in greenhouse type passive solar heating systems

In the research work, a mathematical model of heat processes in the passive solar heating system of the Sunspace type was developed, and on this basis, the annual indicators of the considered system were determined. As the results obtained show, heat losses through the southern wall of an ordinary residential building during the heating season are 16-17 kWh/(m2∙year). The heat input through the southern wall in the heating season is about 125-130 kWh/(m2∙year), and the accumulated energy is 107-114 kWh/(m2∙year), in the presence of a heat accumulator.
