本文件规定了当空气-空气热/能量交换器用作在通风系统中使用的两个气流之间传递热量或热量和水蒸气的装置时，测试和表征其性能的方法。它还规定了用于建筑物能量性能计算的交换器性能表征方法。本文件适用于: -？固定板式换热器（也称回热器）， -？旋转式换热器，包括热轮和总能量轮（也称为再生器）， -？使用传热介质的热管交换器，不包括使用机械泵的热管交换器。 本文件不提供测量换热器对结霜反应的方法。

This document specifies methods for testing and characterizing the performance of air-to-air heat/energy exchangers when used as devices to transfer heat or heat and water vapor between two airstreams used in ventilation systems. It also specifies methods to characterize the performance of exchangers for use in calculation of the energy performance of buildings. This document is applicable to: —？fixed-plate exchangers (also known as recuperators), —？rotary exchangers, including heat wheels and total energy wheels (also known as regenerators), —？heat pipe exchangers using a heat transfer medium, excluding those using mechanical pumping. This document does not provide a method for measuring the response of exchangers to the formation of frost.
