Abstract

This article analysis the running conditions and existing problems of air conditioning system for existing public buildings in the cold and serious cold regions in winter,and compares analysis of the solution of the anti freezing measures for the fresh air unit,introduces the recovery exhaust energy by the means of heat exchange to resolve the existing problems of air conditioning system in winter.The results show that the outdoor temperature changes from -25~10ºC degree, the degree of air supply can reach more than 10 degree ,which means that system which recovers the exhaust energy can preheat the fresh air more than 10 degree.The COP of recovery fresh air heat pump units reaches more than 3.8, and the heat recovery efficiency up to 82%.It can prolong the heat pump units and the fresh air units run in the period of heating, guarantee well IAQ for a long time.
