Abstract:

This paper discusses different schemes of performance of passive solar heating of buildings. Based on the solution for heat conduction equation for active building constructions taking into account the influence of convective heat transfer and heat flux, incoming solar radiation, the ways of energy-saving facilities’ operation is analyzed. It is shown that to increase the efficiency of such systems, an individual design should be performed taking into account the climatic features of the construction area, and the choice of rational combinatorics for outer shell, such as movable shielding heat-protective device, and creating an air gap between the accumulating and heat-insulating layers. Based on the calculations, the energy-active area of the bearing course of buildings, protected from the outer side with the translucent barrier is revealed. The suitable thickness of the accumulation layer for recycling process of solar radiation is determined. The presented innovative technical solutions could help to enhance the efficiency of solar energy utilization and contribute to a more active implementation of passive solar heating, expanding the scope of their territorial application.
