不同气象条件下热回收装置的适用性分析

摘要

With air heat recovery equipment can recover the energy of exhaust,so that the parameters of fresh air into room can get the state point as close as possible to reduce the energy consumption of heating or cooling new wind.The paper chooses Guangzhou,Urumqi with the typical climate,analyzes the outdoor air temperature and humidity parameters on the winter and summer,compares differences of the two fresh air energy consumption and energy savings with the total heat exchanger and significant heat exchanger in the two places,and then points out the principle of the application with the two heat recovery equipments.%采用空气热回收装置可以回收排风中的能量,使送入室内的新风参数尽量接近室内状态点,从而减少加热或冷却新风的能量消耗。选择具有典型气候的广州、乌鲁木齐两城市,对冬夏季室外空气温湿度逐时参数进行了分析,比较了两地新风能耗的差异及全热与显热交换器在上述两地的节能情况,进而指出了两种热回收装置在应用时应遵守的原则。
