18、is document (EN 12102:2013) has been prepared by Technical Committee CEN/TC 113 “Heat pumps and air conditioning units”, the secretariat of which is held by AENOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, a

19、t the latest by January 2014 and conflicting national standards shall be withdrawn at the latest by January 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any

20、 or all such patent rights. This document supersedes EN 12102:2008. The main changes with respect to the previous edition are listed below: a) the addition of a table containing the sound power levels to be recorded in the test report; b) the addition of an Annex ZA relating to the Commission Regula

21、tion (EC) n206/2012. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of

22、this document. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedon

23、ia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 12102:2013EN 12102:2013 (E) 5 1 Scope This European Standard estab

24、lishes requirements for determining, in accordance with a standardized procedure, the sound power level emitted into the surrounding air by air conditioners, heat pumps, liquid chilling packages with electrically driven compressors when used for space heating and/or cooling, including water cooled m

25、ultisplit systems, as described in EN 14511 and dehumidifiers as described in EN 810. This European Standard also covers the measurement of the sound power level of evaporatively-cooled condenser air conditioners, as defined in EN 15218. However, the measurement should be done without external water

26、 feeding and these units will thus be considered as the other air conditioners covered by EN 14511. It is emphasised that this measurement standard only refers to airborne noise. This European Standard offers ways to determine the sound power level of units. Some of them are specifically adapted to

27、provide results with low uncertainties, by using laboratory class acoustic methods and highly controlled working conditions. Those measurements are suitable for certification, labelling and marking purposes. In some cases, the target and/or the environment of the measurements do not allow such preci

28、sion-class methods. This European Standard also offers ways to assess sound power levels with acceptable accuracy even though acoustic methods and/or working conditions are not laboratory-type, e.g. in situ or quality control measurements. This European Standard gives two classes of measurements and

29、 results, according to the test environment: Class A measurements correspond to controlled working conditions (standard or application rating conditions). It is defined by the respect to the tolerances of Table 2 and should be used for the conformity to requirements of the Commission Regulation (EC)

30、 No 206/2012 of 6 March 2012 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for air conditioners Class B measurements correspond to the case where the range defined by the tolerances of Table 2 cannot be fulfilled. In both class

31、es, precision or engineering class acoustic methods should be applied. The choice of the acoustic measurement method is done in accordance with EN ISO 3740 and EN ISO 9614 depending on the type of surrounding acoustic fields (diffuse or free field, enclosed or open space), and the available instrume

32、ntation. Whatever the current working conditions, the reference of acoustic standard should be reported, with explicit mention of its accuracy class. The use of EN ISO 3746 and EN ISO 3747 as survey grade methods are not recommended due to the high level of uncertainties. Their use is only allowed f

33、or non controlled environments. Three methods for determining the sound power levels are specified in order to avoid unduly restricting existing facilities and experience: the first methodology is based on reverberation room measurement (see EN ISO 3741, EN ISO 3743 and EN ISO 3747 in some favourabl

34、e cases when the engineering grade can be fulfilled); the second method is based on measurements in an essentially free field over a reflecting plane (see EN ISO 3744 and EN ISO 3745); the third method is based on sound intensity measurement (see EN ISO 9614) in preferably free field environment. BS

35、 EN 12102:2013EN 12102:2013 (E) 6 The references in this European Standard to EN ISO 3743 should be understood as EN ISO 3743-1 or EN ISO 3743-2 as well. The necessity to regulate the test conditions obviously leads to recommend test methods implemented in acoustically designed (enclosed) spaces, su

36、ch as EN ISO 3741, EN ISO 3743, EN ISO 3745 and also EN ISO 9614 when implemented in an enclosed space. The open spaces should be covered only in specific cases, e.g. when the size or the power of the unit under test cannot be managed by standard test rooms. Suitable test methods are EN ISO 3744 and

37、 EN ISO 9614. NOTE Intensity measurement methods are quite robust and are well suited for tests to be done in environments without or with a light acoustic treatment (the better the acoustic treatment, the easier the implementation). 2 Normative references The following documents, in whole or in par
