The main changes with respect to the previous edition are listed below: a) the addition of requirements related to the electrical co

19、nsumption and the air flow rate measurement of ducted units; b) the addition of a table template containing the test results of the ducted units; c) the addition of an Annex Z related to the Commission Regulation (EC) n206/2012. This document has been prepared under a mandate given to CEN by the Eur

20、opean 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 this document. Although this document has been be prepared in the frame of the commission re

21、gulation (EU) No 206/2012 implementing Directive 2009/125/EC with regard to ecodesign requirements for air conditioners and comfort fans, it is also intended to support the essential requirements of the European Directive 2010/30/CE. According to the CEN/CENELEC Internal Regulations, the national st

22、andards 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 Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

BS EN 15218:2013EN 15218:2013 (E) 4 1 Scope This European Standard specifies the terms, definitions, test conditions, test methods and requirements for r

24、ating the performance of air conditioners and liquid chilling packages, with electrically driven compressors and with evaporatively cooled condenser when used for space cooling. The evaporatively cooled condenser is cooled by air and by the evaporation of external additional water. This additional e

25、xternal water is fed by a specific water supply circuit or by a water tank. This European Standard does not apply to air-to-air and air-to-water air conditioners with a condenser cooled by air and by the evaporation of water condensed on their evaporator. This European Standard applies to units equi

26、pped with a water tank or with a continuous water circuit supply that can also operate without water feeding. However the standard only concerns the testing of these units with water feeding. This European Standard applies to factory-made units which can be ducted. This European Standard applies to

27、factory-made units of either fixed capacity or variable capacity by any means. Packaged units, single split and multisplit systems are covered by this European Standard. With regard to units consisting of several parts, this European Standard applies only to those designed and supplied as a complete

28、 package. Evaporatively cooled condenser units that can also operate in heating mode shall have their performance in this mode determined according to EN 14511. Installations used for industrial processes cooling are not within the scope of this European Standard. This European Standard specifies th

29、e conditions for which performance data shall be declared for compliance to the Ecodesign regulation 206/2012 and to the Energy Labelling regulation 626/2011 of air conditioners with evaporatively cooled condenser in cooling mode.
