本文件规定了测试不包含任何补充加热（除霜）、冷却、加湿或除湿部件的热回收通风机（HRV）和能量回收通风机的通风和能量相关性能的方法。 HRV和ERV的交换器类型为 a） 固定板式换热器（也称为回热器）， b） 旋转交换器，包括热轮和总能量轮（也称为再生器），以及 c） 使用传热介质的热管换热器，不包括使用机械泵的换热器， 本文件未提供测量交换器对结霜反应的方法。

This document specifies a method of testing the ventilation and energy related performance of heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) that do not contain any supplemental heating (except for defrost), cooling, humidification, or dehumidification components. Exchanger types of HRVs and ERVs are a) fixed-plate exchangers (also known as recuperators), b) rotary exchangers, including heat wheels and total energy wheels (also known as regenerators), and c) 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.
