(Main)Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling - Part 1: Terms and definitions
General Information
- Abstract
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. 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,
- 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 covered 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 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 are not covered by this standard, see EN 15218 for evaporatively cooled condenser units.
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 prEN 14825.
NOTE 2 All the symbols given in this text should be used regardless of the language used.
