Air conditioners and liquid chilling packages with evaporatively cooled condenser and with electrically driven compressors for space cooling - Terms, definitions, test conditions, test methods and requirements
This standard specifies the terms, definitions, test conditions, test methods and requirements for rating the performance of air conditioners and liquid chilling packages, with electrically driven compressors and with evaporatively cooled condenser when used for space cooling. The evaporatively cooled condenser is cooled by air and by the evaporation of external additional water. This additional external water is fed by a specific water supply circuit or by a water tank.
This standard does not apply to air-to-air and air-to-water air conditioners with a condenser cooled by air and by the evaporation of water condensed on their evaporator.
This standard does not apply to units equipped with a water tank or with a continuous water circuit supply that cannot operate without water feeding.
This standard applies to factory-made units which can be ducted.
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.
With regard to units consisting of several parts, this standard applies only to those designed and supplied as a complete package.
Installations used for industrial processes cooling are not within the scope of this standard.

Diese Norm legt die Begriffe, Prüfbedingungen, Prüfverfahren und Anforderungen für die Einstufung und Leis-tung
von Luftkonditionierern und Flüssigkeitskühlsätzen mit elektrisch angetriebenen Verdichtern und dampf-gekühlten
Verflüssigern für die Raumkühlung fest. Der dampfgekühlte Verflüssiger wird durch Belüftung und
durch Verdampfung von zusätzlichem, von außen zugeführtem Wasser abgekühlt. Dieses zusätzliche Wasser
wird über einen speziellen Wasserversorgungskreislauf oder einen Wasserbehälter von außen zugeführt.

durch Verdampfung des an ihrem Verdampfer kondensierten Wassers abgekühlt wird.
Diese Norm gilt nicht für Geräte, die mit einem Wasserbehälter oder einem Wasserkreislauf mit konstanter
Versorgung versehen sind, die ohne diese Wasserzuleitung nicht betrieben werden können.
Diese Norm gilt für fabrikmäßig zusammengebaute Geräte, die mit Luftkanalanschlüssen versehen sein
können.
Diese Norm gilt für fabrikmäßig zusammengebaute Geräte mit fest eingestellter oder durch beliebige Vorrich-tungen
zu verändernder Leistung (variable Leistung).
Kompaktgeräte, Einzelgeräte in Split-Bauweise und Multi-Split-Systeme fallen in den Anwendungsbereich
dieser Norm.
Wenn die Geräte aus mehreren Teilen bestehen, gilt diese Norm nur für die Teile, die als vollständige Bau-einheit
konstruiert und geliefert werden.
Anlagen für die Kühlung industrieller Prozesse fallen nicht in den Anwendungsbereich dieser Norm.

NOTE Desuperheating and sub-cooling of the refrigerant may occur as well 3.2 water tank tank designed as an integral part of the unit to contain external additional water which is fed to the evaporatively cooled condenser 3.3 continuous supply water circuit circuit designed as an integral part of the unit to feed continuously the evaporatively cooled condenser with water from an external water source 3.4 effective power input PE average electrical power input of the unit within a defined interval of time obtained from: power input for operating the compressor; power input for all control and safety devices of the unit; power input of the circulating pump which provides water to the evaporatively cooled condenser, if any; proportional power input of the conveying devices (e.g. fans, pumps) for ensuring the transport of the heat transfer media inside the unit. Expressed in Watt. For the purpose of this standard the present definition replaces the one in EN 14511-1:2004 and it shall be used to calculate the EER 3.5 cleaning cycle interval of time during which water is sprayed on the evaporatively cooled condenser in order to remove fouling and scale buildup 3.6 functioning cycle interval of time elapsed between the start of two successive cleaning cycles for evaporatively cooled condenser units with a continuous water supply 4 Classification If the heat transfer medium for the indoor heat exchanger is water, the unit shall be denominated as evaporatively cooled condenser liquid chilling package.
