摘　　要：目前对于空气-空气热回收装置的节能性问题没有清晰准确的算法与评价指标。为了准确地分析与评价空气-空气热回收装置的节能性,提出了针对空气-空气热回收装置的节能率的概念,并在此基础上提出了该节能率的算法,节能率公式由决定装置节能性的关键参数组成,可以简便准确地对空气-空气热回收装置的节能率进行计算。并以北京地区为例,使用节能率计算公式对不同种类的空气-空气热回收装置的节能性进行了计算比较,节能率计算结果可以简单直观地对装置的节能性做出评价。There is no clear and accurate algorithm or evaluation index for the energy saving performance of air to air heat recovery unit at present. In order to accurately analyze and evaluate the energy saving performance of air to air heat recovery unit, the concept of energy saving rate for air to air energy recovery unit was proposed and an algorithm for energy saving rate was proposed on this basis. The energy saving rate formula is composed of key parameters determining the energy saving performance of the unit. The formula is simple and accurate to calculate the energy saving rate of the air to air energy recovery unit. Taking Beijing area as the example, the energy saving performance of different kinds of air to air heat recovery units＇ was calculated and compared by using the formula of energy saving rate. Through the calculation results＇ of energy saving rate, the energy saving performance of the unit can be evaluated intuitively and easily.
