暖通空调系统的空对空能量回收交换器的性能主要由交换器的效率和压降决定。有效性取决于几个参数，如供给和排气质量流量以及装置的能量传递特性。由于这种组合，必须为每种单独类型的设备建立性能数据。本节介绍了应用ASHRAE标准84-78的方法来确定四种设备性能的结果:1）线圈能量回收回路（闭合绕线）系统；2） 热管换热器；3） 固定板式换热器； 4）双塔焓回收回路（开环）系统。引用:ASHRAE交易，第87卷，第一部分，伊利诺伊州芝加哥

The performance of an HVAC system’s air-to-air energy recovery exchanger is defined primarily by the exchanger’s effectiveness and pressure drop. The effectiveness is dependent on several parameters such as the supply and exhaust mass flow rates and the energy transfer characteristics of the device. Because of this combination, performance data must be established for each individual type of device. This section presents the results of applying the methodology of ASHRAE Standard 84-78 in determining the performance of four types of devices: 1) coil energy recovery loop (closed run-around) system; 2) heat pipe heat exchanger; 3) fixed plate exchanger; and 4) the twin-tower enthalpy recovery loop (open run-around) system.
