Comblned air and heating supply systems of airproof buildings

Abstract

Nowadays the exterior envelope of buildings demands the constant increase in its heat-shielding characteristics. The buildings are designed according to the normative base of the Republic of Belarus. But on the stage of calculating the temperature balance there often occurs the following situation: the heat loss is much less than the heat gains. In this case the entire heating load is directed to the heating of infiltrating air. This air has to be taken inside disorderly but that is not possible because of the high airtight packing of the building envelope. This report represents the technological schemes and practical solutions to the effective energy and heat air supply to the leak tight buildings.
