BS EN 15218:2022

This document 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 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 document is not applicable 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 document is applicable to units equipped with a water tank or with a continuous water circuit supply that can also operate without water feeding. However, this document only concerns the testing of these units with water feeding. This document is applicable to factory-made units which can be ducted. This document is applicable 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 document. With regard to units consisting of several parts, this document applies only to those designed and supplied as a complete package. For evaporatively cooled condenser units that can also operate in heating mode, their performance in this mode is determined according to EN 14511:2022 (all parts). Units used for industrial processes cooling are not within the scope of this document. This document specifies the conditions for which performance data will be declared for compliance with the Ecodesign Regulation 206/2012 and with the Energy Labelling Regulation 626/2011 of air conditioners with evaporatively cooled condenser in cooling mode.
