介绍了带乙二醇循环装置热回收空调系统的组成、工作原理 ,并以上海某建筑为例 ,比较了绕流二盘管、绕流三盘管及常规的采用再热的空调系统的能耗 ,认为在上海地区 ,采用绕流二盘管系统可节能 2 3.3% ,采用绕流三盘管系统可节能 46.6%。绕流环路热回收技术在空调节能方面具有广阔应用前景 The composition and working principle of the heat recovery air conditioning system with ethylene glycol circulation unit are introduced. Taking a building in Shanghai as an example, the comparison between the two bypass coils, the three bypass coils and the conventional air conditioning system with reheat Consumption, that Shanghai in the area, the use of bypass two-coil system can save energy 23.3%, using bypass three-coil system can save 46.6%. Flow around the loop heat recovery technology in the air conditioning energy saving has broad application prospects
