This European Standard shall be given the status of a national standard, either by

16、 publication of an identical text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by April 2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and su

17、pports essential requirements of EU Directive(s). For relationship with EU Directive 2002/31/EC, see informative annex ZA, which is an integral part of this document.

19、 Kingdom. EN 15218:2006 (E) 4 1 Scope This standard specifies the terms, definitions, test conditions, test methods and requirements for rating the performance of air conditioners and liquid chilling packages, with electrically driven compressors and with evaporatively cooled condenser when used for

20、 space cooling. The evaporatively cooled condenser is cooled by air and by the evaporation of external additional water. This additional external water is fed by a specific water supply circuit or by a water tank. This standard does not apply to air-to-air and air-to-water air conditioners with a co

21、ndenser cooled by air and by the evaporation of water condensed on their evaporator. This standard does not apply to units equipped with a water tank or with a continuous water circuit supply that cannot operate without water feeding. This standard applies to factory-made units which can be ducted.

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

23、omplete package. Installations used for industrial processes cooling are not within the scope of this standard. NOTE All the symbols given in this text should be used regardless of language. 2 Normative references The following referenced documents are indispensable for the application of this docum
