Scope

This document specifies the terms and definitions for the rating and performance of air conditioners, liquid chilling packages and heat pumps using either air, water or brine as heat transfer media, with electrically driven compressors when used for space heating and/or cooling. It also specifies the terms and definitions for the rating and performance of process chillers. This document does not apply to heat pumps for domestic hot water, although certain definitions can be applied to these. This document applies to: — factory-made units that can be ducted, — factory-made liquid chilling packages with integral condensers or for use with remote condensers, and — air-to-air air conditioners which can also evaporate the condensate on the condenser side. Packaged units, single split and multisplit systems are covered by this document. Single duct and double duct units are covered by this document, as well. In the case of units consisting of several parts, this document applies only to those designed and supplied as a complete package, except for liquid chilling packages with remote condenser. This document is primarily intended for water and brine chilling packages but can be used for other liquid subject to agreement. The units having their condenser cooled by air and by the evaporation of external additional water will have their performance in the cooling mode determined in accordance to EN 15218. For those which can also operate in the heating mode, the EN 14511 series applies for the determination of their performance in the heating mode. Part load testing of units is dealt with in EN 14825. All the symbols given in this text are used regardless of the language.
