TS EN 14511-1
Air conditioners, liquid chilling packages and heat pumps for space heating and cooling and process chillers, with electrically driven compressors - Part 1: Terms and definitions
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.
NOTE 1 Part load testing of units is dealt with in EN 14825.
NOTE 2 All the symbols given in this text are used regardless of the language.

About This Item
TS EN 14511-1 is the terminology and definition standard for air conditioners, liquid chilling packages and heat pumps with electrically driven compressors, together with process chillers. It establishes the common technical language used when rating and describing heating and cooling performance, so that different equipment types can be identified and compared consistently.
Equipment families and application context
The standard covers systems using air, water or brine as heat transfer media, and it includes factory-made air conditioners, liquid chilling packages, heat pumps and process chillers. Packaged units, single split and multisplit systems, as well as single-duct and double-duct units, are within its scope. In general engineering terms, these products move heat rather than create it, making them central to comfort air conditioning and many industrial cooling applications.
Where the definitions apply, and where they do not
The document is intended primarily for water and brine chilling packages, but it may be used for other liquids by agreement. It does not apply directly to domestic hot water heat pumps, although some definitions can still be relevant to them. For units cooled by air and by evaporation of external additional water, cooling-mode performance is determined according to EN 15218, while part-load testing is addressed in EN 14825. For units that also operate in heating mode, the EN 14511 series is used for performance determination in that mode.
- Provides a shared vocabulary for rating and performance descriptions.
- Covers air, water and brine heat transfer media.
- Includes packaged, split, multisplit and ducted unit arrangements.
- Addresses process chillers alongside comfort cooling equipment.
- Points users to related standards for specific performance determinations.
