Abstract
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.
