33、13141-7:2010 (E) 5 Introduction This European Standard specifies methods for the performance testing of components used in residential ventilation systems to establish the performance characteristics as identified in EN 13142. This European Standard does not contain any information on ductwork and f
34、ittings, which are covered by other European Standards. The standard can be used for the following applications: laboratory testing; attestation purposes. 1 Scope This part of EN 13141 specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal and acoustic pe
35、rformance, and the electrical performance characteristic of a mechanical supply and exhaust ventilation units used in a single dwelling. It covers unit that contain at least, within one or more casing: supply and exhaust air fans; air filters; air-to-air heat exchanger and/or Extract Air-to-Outdoor
36、Air heat pump for extract 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. The different possible arrangements of heat recovery heat exchangers and/or heat pumps are described in Annex A. This s
37、tandard does not deal with non-ducted units or reciprocating heat exchangers. This standard does not deal with units that supply several dwellings. This standard does not cover ventilation systems that may also provide water space heating and hot water. This standard does not cover units including c
38、ombustion engine driven compression heat pumps and absorption heat pumps. Electrical safety requirements are given in EN 60335-2-40 and EN 60335-2-80.
