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 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 condenser 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. 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 complete 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.
