This European Standard shall be given the status of a national
22、 standard, either by publication of an identical text or by endorsement, at the latest by September 2014, and conflicting national standards shall be withdrawn at the latest by September 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of pate
23、nt rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13141-8:2006. In comparison to EN 13141-8:2006 the following changes have been made: alternating ventilation units including a storage type heat exchangers have been
24、 included; measurement of the deviation of air flow rate due to faade pressures in normal use has been introduced; temperature conditions have been modified to be the same as in EN 13141-7 that is to say 7 C / 20 C.

BS EN 13141-8:2014EN 13141-8:2014 (E) 5 Introduc
30、tion 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,
31、 especially 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 followi
32、ng applications: 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.

33、ces BS EN 13141-8:2014EN 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 in a s
34、ingle 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 humi
35、dity 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 certain
36、 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 ducted uni
37、ts 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.
