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.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
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 on
the 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.

unit
2.7
single split unit
factory assembly of components of refrigeration system fixed on two mountings to form a discrete
matched functional unit
2.8
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
2.9
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
2.10
liquid chilling package
factory-made unit designed to cool liquid, using an evaporator, a refrigerant compressor, an integral or
remote condenser and appropriate controls

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 through the refrigerating system for use to unit whose primary control remains in the heating
mode (e.g. variable refrigerant flow)
2.18
indoor heat exchanger
heat exchanger which is designed to transfer heat between the refrigerant and the indoor heat transfer
medium
Note 1 to entry: In the case of an air conditioner or heat pump operating in the cooling mode, this is the
evaporator. In the case of an air conditioner or heat pump operating in the heating mode, this is the condenser.
2.19
outdoor heat exchanger
heat exchanger which is designed to transfer heat between any available heat source and the refrigerant
Note 1 to entry: In the case of an air conditioner or heat pump operating in the cooling mode, this is the
condenser. In the case of an air conditioner or heat pump operating in the heating mode, this is the evaporator.
