This document supersedes EN 14511-1:2011. The main change with respect to the previous edition is the addition of terms and definitions.

15、Although this document has been prepared in the frame of the commission regulation (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

19、4 1 Scope This European Standard 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.

20、This European Standard does not apply to heat pumps for domestic hot water, although certain definitions can be applied to these. This European Standard applies to: factory-made units that can be ducted, factory-made liquid chilling packages with integral condensers or for use with remote condensers

21、, factory-made units of either fixed capacity or variable capacity by any means, 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 standard. Single duct and double duct units are cove

22、red by the standard. In the case of units consisting of several parts, this European Standard applies only to those designed and supplied as a complete package, except for liquid chilling packages with remote condenser. This European Standard is primarily intended for water and brine chilling packag

23、es 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 should have their performance in the cooling mode determined in accordance to EN 15218. For those which can also operate in the heating mode, E

24、N 14511 applies for the determination of their performance in the heating mode. Installations used for heating and/or cooling of industrial processes are not within the scope of this standard. NOTE 1 Part load testing of units is dealt with in EN 14825. NOTE 2 All the symbols given in this text are

25、used regardless of the language used. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 air conditioner a device capable of cooling or heating, or both, indoor air, using a vapour compression cycle driven by an electric compressor, including ai
