摘　　要：提出了由全热回收与热泵热回收组成的两级排风热回收新风机组,并将其应用于风机盘管空调系统实现温湿度独立控制.选取南京地区某办公建筑为研究对象,利用DeST软件计算了建筑全年逐时冷负荷,建立了系统性能计算数学模型,编制程序对该系统在典型年供冷性能进行模拟分析.模拟结果表明,该系统可以很好地实现温湿度独立控制,供冷平均性能系数为4.58,与常规空调相比,节能率约为42.8%.The exhaust air heat recovery fresh air unit, which consists of total heat exchanger and heat pump unit, was put forward, and the fresh air unit, was applied in fan coin air conditioning system for realizing temperature and humidity independent control. An office building in Nanjing is selected, and the annual hourly air conditioning load is calculated by DeST software. The mathematic model for simulating performance of the system is set up. The simulation analysis of cooling performance of the system in typical year is carried out. The simulation results showed that the system can independent control temperature and humidity well, and the coefficient of performance （COP） of the system is 4.58. The energy saving rate of the system is 42.8% compared with conventional air conditioning system.
