Abstract
Two schemes of arrangement of air exchange (the traditional one based on mixing, and the modern one based on displacement) are compared. It is shown that the use of the displacement scheme of arrangement of air exchange leads to considerable reduction of energy consumption with the year round operation of air conditioning system and to improvement of sanitary and hygiene qualities of the air.
