摘　　要：新风能耗要占夏季空调负荷的20%～40%,新风回收越来越受到人们的重视,新风换气机得到了一定程度的普及。针对北京夏季新风负荷的特点,对市场上流行的新风换气机进行能耗回收分析,得出夏季工况显热通风换气机回收效率极低,全热通风换气机能减少一半的负荷。The fresh air energy consumption accounts for 20%-40% of the air conditioning load in summer, as a result, fresh air recovery has been paying more attention by people. The fresh air exchanger has been popular. According to the characteristics of fresh air load in Beijing in summer, the heat recovery of common fresh air exchangers on market was analyzed. Finally, a conclusion was shown that the heat recovery efficiency of obvious heat exchanger is extremely low, however, the entire heat exchanger can reduce the heat load by half in summer working condition.
