摘　　要：以夏热冬冷地区3个典型建筑为例,分析了3类典型建筑的总冷(热)负荷、新风冷(热)负荷分布情况,计算了采用排风热回收装置处理新风后降低的负荷量,并对采用新风换气装置后的投资进行了经济性分析.采用新风换气装置后总投资变化不大,但运行费用却能大大降低.In this paper, taking three typical buildings in hot summer and cold winter area as an example, the author analyzes the distribution of the three kinds of typical building total cold （heat） load and the fresh air cool （heat） load, calculates the load reduce after the fresh air treated by the exhaust heat recovery unit and analyzes the economic efficiency of the fresh air exchange device. Little change in the total investment by the fresh air exchange device, but it can reduce the operation cost.
