Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling - Part 2: Test conditions
This part of EN 14511 specifies the test conditions for the rating of air and water cooled air conditioners, liquid chilling packages, air-to-air, water-to-air, air-to-water and water-to-water heat pumps with electrically driven compressors when used for space heating and/or cooling. It also specifies test conditions for heat recovery operation of multisplit systems.
This European Standard applies to factory made units that can be ducted.
This standard applies to factory made liquid chilling packages with integral condensers or for use with remote condensers.
This standard applies to factory-made units of either fixed capacity or variable capacity by any means.
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, the standard applies only to those designed and supplied as a complete package, except for liquid chilling packages with remote condenser.
This standard is primarily intended for water and brine chilling packages but can be used for other liquid subject to agreement.
This standard applies to air-to-air air conditioners which evaporate the condensate on the condenser side.
The units having their condenser cooled by air and by the evaporation of external additional water are not covered by this standard.
This standard does not apply to units using transcritical cycles, e.g. with CO2 as refrigerant.
Installations used for heating and/or cooling of industrial processes are not within the scope of this standard.
NOTE Part load testing of units is dealt with in CEN/TS 14825.
