Ventilation for buildings - Performance testing of components/products for residential ventilation - Part 8: Performance testing of un-ducted mechanical supply and exhaust ventilation units (including heat recovery) for mechanical ventilation systems intended for a single room; German version EN 13141-8:2014

Title (German)

Lüftung von Gebäuden - Leistungsprüfung von Bauteilen/Produkten für die Lüftung von Wohnungen - Teil 8: Leistungsprüfung von mechanischen Zuluft- und Ablufteinheiten ohne Luftführung (einschließlich Wärmerückgewinnung) für ventilatorgestützte Lüftungsanlagen von einzelnen Räumen; Deutsche Fassung EN 13141-8:2014


Standard series EN 13141 specifies methods for the performance testing of components used in residential ventilation systems to establish the performance characteristics as identified in EN 13142. DIN EN 13141-8 incorporates many references to other European and International Standards, especially regarding characteristics other than aerodynamic characteristics, such as acoustic characteristics. In most cases, some additional tests or some additional conditions are given for the specific use in residential ventilation systems. The standard is applicable to the following: - laboratory testing; - attestation purposes. DIN EN 13141-8 describes the laboratory test methods and the requirements for testing aerodynamic, thermal and acoustic performance as well as for the electrical power of an un-ducted mechanical supply and exhaust ventilation unit used in a single room. In general, such a ventilation unit contains: - supply and exhaust air fans; - air filters; - air to air heat exchanger or air storage mass for exhaust air heat and humidity recovery; - control system; - inlet and outlet grilles. Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be used together. Such equipment can contain alternating heat exchangers which provide separate supply and exhaust air flows. Ducted units or units with heat pumps are not intended to be covered by the planned European Standard. The safety requirements are given in EN 60335-2-80. In comparison to EN 13141-8:2006, the following changes have been made: - alternating ventilation units including a storage type heat exchangers have been included; - measurement of the deviation of air flow rate due to façade pressures in normal use has been introduced; - efficiency and air flow values have been corrected based on leakage rates and deviations; - temperature conditions have been modified to be aligned with EN 13141-7 that is to say 7 °C/20 °C. This document (EN 13141-8:2014) has been prepared by Technical Committee CEN/TC 156 "Ventilation for buildings" (secretariat: BSI, United Kingdom). The responsible German committee is Working Committee NA 041-02-51 AA "Lüftung von Wohnungen" ("Residential ventilation") of the Heating and Ventilation Technology Standards Committee (NHRS) at DIN, the German Institute for Standardization e. V.
