This document specifies requirements and testing for rating and performance of Non Residential Ventilation Units, NRVU’s, specifically Air Handling Units (AHU’s). It specifies requirements, classifications and testing of components and sections of air handling units.
This document applies to tests in a laboratory and in situ. This document is applicable both for mass produced air handling units and tailor-made Air Handling Units.
This document applies to AHU and individual sections of AHU with the designed air flow > 250 m3 · h?1. This document applies to UVU’s with additional air treatment components in addition to filtration.
This standard does not include:
-
residential unidirectional and bidirectional ventilation units;
-
nonresidential unidirectional ventilation units which consist of only a casing, a fan with or without filter.
Residential ventilation units are covered by EN 13142 .
Nonresidential unidirectional ventilation units which consists only casing, fan with or without filter are covered by EN 17291 .
