DIN EN 13141-8:2014-09 EN 13141-8:2014 (E) 5 Introduction
34、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 1. This European Standard incorporates many references to other European and International Standards, espe
35、cially on characteristics other than the aerodynamic characteristics, for instance on acoustic characteristics. In most cases some additional tests or some additional conditions are given for the specific use in residential ventilation systems. This European Standard can be used for the following ap
36、plications: laboratory testing; attestation purposes. The position of this European Standard in the field of standards for the mechanical building services is shown in Figure 1.

37、ces DIN EN 13141-8:2014-09 EN 13141-8:2014 (E) 7 1 Scope This European Standard specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal and acoustic performance, and the electrical power of an un-ducted mechanical supply and exhaust ventilation unit used i
38、n a single room. The purpose of this European Standard is not to consider the quality of ventilation but to test the performance of the equipment. In general, 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
39、 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. In ce
40、rtain cases, i.e. alternating ventilation unit, the manufacturer may recommend that the equipment can be installed in such a way that it serves more than one room. For the purpose of this European Standard, these products are assessed in a single room. This European Standard does not deal with ducte
41、d units or units with heat pumps. Safety requirements are given in EN 60335-2-80:2003 2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
