DIN EN 13141-7:2022

Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 7: Performance testing of ducted mechanical supply and exhaust ventilation units (including heat recovery); German version EN 13141-7:2021

EN 13141 series specifies methods for the performance testing of components used in residential ventilation systems to establish the performance characteristics as identified in EN 13142:2021. This part does not contain any information on ductwork and fittings, which are covered by other European Standards. The standard can be used for the following applications: — laboratory testing; — attestation purposes. This document specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal, acoustic and electrical performance characteristics of ducted mechanical supply and exhaust residential ventilation units. The standard is applicable to unit that contain at least, within one or more casing: — fans for mechanical supply and exhaust; — air filters; — air-to-air heat exchanger and/or air-to-air heat pump for air heat recovery; — control system. Such unit can be provided in more than one assembly, the separate assemblies of which are designed to be used together. Examples of different possible arrangements of heat recovery, heat exchangers and/or heat pumps are described in Annex A. This document covers ventilation units with continuous mass flows for each setting point. It does not deal with non-ducted units that are treated in prEN 13141 8:2021. The document does not cover ventilation systems that may also provide water space heating and hot water that are treated in EN 16573 and does not cover units including combustion engine driven compression heat pumps and absorption heat pumps. Electrical safety requirements are given in EN 60335-2-40 and EN 60335-2-80.
