This European Standard specifies methods to be used for testing of air-to-air heat recovery components (HRC). The main purpose of the HRC shall be to - preheat or heat and/or - precool or cool supply air in ventilation systems or air conditioning systems. Optional HRC can exchange air humidity between exhaust and supply air. The HRC contain the heat exchangers and all necessary features and auxiliary devices for the exchange of sensible heat and (if available) air humidity between exhaust air and supply air. The HRC will be installed in casings or air ducts. If fans are part of the test unit, the effect of the fan power on the measured values shall be corrected. This European Standard specifies procedures and input criteria required for tests to determine the performance of a HRC at one or several test conditions, each of them with continuous air flows, air temperatures and humidities at both inlet sides. Three different test types are covered: - Laboratory testing of HRC - Laboratory testing of HRC installed in non-residential air handling units (definition according Commission Regulation(EU) No 1253/2014) in design configuration - On-site (field) testing of HRC in non-residential air handling units or systems in operation configuration. This European Standard is applicable to recuperators and regenerators intended for exchange of sensible heat and optionally for exchange of air humidity. This European Standard prescribes test methods for determining: 1. the temperature and humidity efficiency 2. the pressure drop of exhaust air and supply air sides 3. possible internal leakages; exhaust air transfer ratio (EATR) and outdoor air correction factor (OACF)and 4. auxiliary energy used for the operation of the HRC. HRC using heat pumps are not covered by this standard.
