Overview

The standard series EN 13141 describes the performance testing of components/products for residential ventilation. The new edition of EN 13141-6 specifies test methods on ventilation system packages and permits to avoid testing each component separately. The standard gives laboratory methods for measuring the aerodynamic and acoustic performance characteristics and energy consumption of assembled exhaust ventilation system packages for a single dwelling. If a component of the package is not physically linked to the others (such as air inlets), then it is assumed to have been tested according to the test method related to this component. The purpose of this standard is to provide characteristics for a ventilation system package tested under worst case conditions. It is assumed that better values are achieved on site when the ventilation system package is installed in accordance with the manufacturer's instructions and within the limits of the test conditions given in this standard. The performance characteristics of the components/products for residential ventilation are given in EN 13142. This new edition supersedes DIN EN 13141-6:2004. With respect to DIN EN 13141-6:2004, the following modifications have been made: a) in Clause 3, the following terms and definitions have been introduced: maximum and minimum air volume flows (q_vmax and q_vmin), demand control ventilation (DCV), boosted air volume flow (q_vboost), short duct and long duct and reference configuration (for the energy efficiency calculation); b) in 5.2.2, differentiation of the duct connecting the roof/wall outlet to the fan unit considering whether the fan unit outlet is situated on top or on a face of the fan unit; c) modification of Figure 6 describing the types of long ducts and long branched ducts (it now explains how to deal with long branched ducts with more than 3 spigots); d) modification of Table 1 for the presentation of the aerodynamic characteristics; e) in Clause 6, a procedure has been added for the measurement of external leakage; f) Table 2 has been added giving a classification of the external leakage; g) in Clause 7, specification of the test conditions for the measurement of the electrical power; h) in Clause 8, a paragraph has been added defining the test conditions and calculation for energy efficiency; i) Table 3 has been prepared for the presentation of the power consumption results; j) in Clause 9, specification of the acoustic test conditions; k) in A.1, modification and explanation of Figure A.1 representing an example of compensating mounting for air flow measurement device. This document (EN 13141-6:2014) has been prepared by Technical Committee CEN/TC 156 "Ventilation for buildings". 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.
