  • Description: The article shows results of studies on assessing the effectiveness of new principles for heat recovery of exhaust air in ventilation systems of apartment buildings (AB). Technological solutions are known that provide heat recovery of the exhaust air for heating the supply air of ventilation systems. The efficiency of such solutions can reach 90%, but only in the coldest five-day period of the year with the maximum temperature difference between the exhaust and supply air. At all other times of the heating season, the efficiency of the recuperative heat exchangers decreases as the outside air temperature rises. In the studies presented in the article, a technology was considered that was free from this drawback. It is based on a two-stage heat recovery of the exhaust air: first, recovery for heating the supply air, and then “additional recovery” using heat pumps for the needs of AB hot water supply. The article shows results of assessing the effectiveness of the proposed two-stage heat recovery of exhaust air in various regions of the Russian Federation.
