Abstract
The article deals with the issues of the increase of solar energy use in engineering systems of civil buildings. The mathematical model was built and the study of the work of the one-contoured system of hot water-supply, accumulating the day solar energy and consuming it during the day was carried out. On the basis of the analytical study the dependences, reflecting the temperature changes of a heat carrier and the value of accumulated solar heat energy in the tank-accumulator during the daylight hours were received. The process of day discharge of a tank-accumulator during the work of a system of building’s hot water-supply was also built. The pre-conditions of the organization of the structure of cyclic operation of solar installations were obtained. The choice of tank-accumulator volume and its quantity that prevents boiling up of a heat carrier in solar collectors was grounded. The example of tank-accumulator capacities selection, taking into account their alternate work was given. The research results allow to design the installations that will secure the trouble-free work of the one-contoured system of solar hot water-supply with high efficiency during the transitional and summer periods without the constant use of a duplicate heat source during the night.
