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 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.
It also specifies the terms and definitions for the rating and performance of process chillers.
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 should 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.

Klimatske naprave, enote za hlajenje kapljevine, toplotne črpalke za ogrevanje in hlajenje prostora ter procesne hladilne naprave z električnimi kompresorji - 1. del: Izrazi in definicije
Ta evropski standard določa izraze in definicije za ocenjevanje in delovanje klimatskih naprav, enot za hlajenje kapljevine in toplotnih črpalk, ki uporabljajo zrak, vodo ali slanico kot medij za prenos toplote, z električnimi kompresorji, kadar se uporabljajo za ogrevanje in/ali hlajenje prostora.
Določa tudi izraze in definicije za ocenjevanje in delovanje procesnih hladilnih naprav.
Ta evropski standard se ne uporablja za toplotne črpalke za gospodinjsko vročo vodo, čeprav se lahko za njih uporabljajo nekatere definicije.
Ta evropski standard se uporablja za:
– tovarniško izdelane enote, ki jih je mogoče opremiti s kanali,
– tovarniško izdelane enote za hlajenje kapljevine z vgrajenimi kondenzatorji ali za uporabo z oddaljenimi kondenzatorji,
– tovarniško izdelane enote bodisi fiksne ali spremenljive zmogljivosti na kakršen koli način in
– zračne klimatske naprave, ki lahko poskrbijo tudi za izhlapevanje kondenzata na strani kondenzatorja.
Ta standard zajema pakirane enote in sisteme z enim ali več razcepi. Ta standard zajema enote z enojnim in dvojnim jaškom.
Pri enotah, sestavljenih iz več kosov, se ta evropski standard uporablja samo za tiste, ki so zasnovane in dostavljene kot celoten paket, razen za enote za hlajenje kapljevine z oddaljenim kondenzatorjem.
Ta evropski standard je prvotno namenjen enotam za hlajenje z vodo in slanico, vendar se lahko po dogovoru uporablja tudi za druge tekočine.
Delovanje hlajenja pri enotah, ki kondenzator hladijo z zrakom in z izhlapevanjem zunanje dodatne vode, naj se določi v skladu s standardom EN 15218. Pri enotah, ki lahko delujejo tudi v načinu gretja, se skupina standardov EN 14511 uporablja za določevanje njihovega delovanja pri gretju.

1 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,
— 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 document. Single duct and double
duct units are covered by the document.
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.
2 Normative references
There are no normative references in this document.

3.1
air conditioner
device capable of cooling or heating, or both, indoor air, using a vapour compression cycle driven by an
electric compressor, including air conditioners that provide additional functionalities such as
dehumidification, air purification, ventilation or supplemental air heating by means of electric resistance
heating, as well as appliances that may use water (either condensate water that is formed onthe
evaporator side or externally added water) for evaporation on the condenser, provided that the device is
also able to function without the use of additional water, using air only
Note 1 to entry: Appliances using additional external water are rated according to EN 15218.
3.2
heat pump
encased assembly or assemblies designed as a unit, using a vapour compression cycle driven by an
electric compressor, to provide delivery of heat
Note 1 to entry: It can have means for cooling, circulating, cleaning and dehumidifying the air. The cooling is by
means of reversing the refrigerating cycle.
Note 2 to entry: Also known as a reverse cycle air conditioner, when cooling and heating air.
3.3
comfort air conditioner or heat pump
air conditioner or heat pump to satisfy the comfort requirements of the occupants of the air conditioned
room
3.4
close control air conditioner
air conditioner to satisfy the requirements of the process carried out in the air conditioned room
3.5
control cabinet air conditioner
air conditioner to satisfy the requirements of the control cabinet
3.6
packaged unit
factory assembly of components of refrigeration system fixed on a common mounting to form a discrete
unit
3.7
single split unit
factory assembly of components of refrigeration system fixed on two mountings to form a discrete
matched functional unit

3.8
single-duct air conditioner
air conditioner in which, during cooling or heating, the condenser (or evaporator) intake air is introduced
from the space containing the unit and discharged outside this space
3.9
double-duct air conditioner
air conditioner in which, during cooling or heating, the condenser (or evaporator) intake air is introduced
from the outdoor environment to the unit by a duct and rejected to the outdoor environment by a second
duct, and which is placed wholly inside the space to be conditioned, near a wall

liquid chilling package
factory-made unit designed to cool liquid, using an evaporator, a refrigerant compressor, an integral or
remote condenser and appropriate controls

3.17
heat recovery
recovery of heat rejected by the unit whose primary control is in the cooling mode by means of either an
additional heat exchanger (e.g. a liquid chiller with an additional condenser) or by transferring the heat

variable refrigerant flow)
