Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling - Part 1: Terms and definitions
This part of EN 14511 specifies the terms and definitions for the rating and performance 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. This European Standard does not specifically apply to heat pumps for sanitary hot water, although certain definitions can be applied to these.
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, this 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 1 Part load testing of units is dealt with in CEN/TS 14825.
NOTE 2 All the symbols given in this text should be used regardless of the language used.
Luftkonditionierer, Flüssigkeitskühlsätze und Wärmepumpen mit elektrisch angetriebenen Verdichtern für die Raumbeheizung und Kühlung - Teil 1: Begriffe
Dieser Teil der EN 14511 legt die Begriffe für die Einstufung und Leistung von luft- und wassergekühlten Luft-konditionierern, Flüssigkeitskühlsätzen, Luft/Luft-, Wasser/Luft-, Luft/Wasser- und Wasser/Wasser-Wärme-pumpen mit elektrisch angetriebenen Verdichtern für die Raumheizung und/oder -kühlung fest.

Kompaktgeräte, Einzelgeräte in Split-Bauweise und Multi-Split-Systeme fallen unter den Anwendungsbereich dieser Norm. Geräte mit Ein- und Zweikanal-Systemen werden ebenfalls in dieser Norm behandelt. Wenn die Geräte aus mehreren Teilen bestehen, gilt diese Norm mit der Ausnahme von Flüssigkeitskühl-sätzen mit getrennt angeordnetem Verflüssiger nur für die Teile, die als vollständige Baueinheit konstruiert und geliefert werden. Diese Norm gilt hauptsächlich für Wasser- und Solekühlsätze, kann jedoch bei Vereinbarung auf weitere Flüssigkeitskühlsätze angewendet werden. Diese Norm gilt für Luft/Luft-Luftkonditionierer, die das Kondensat auf der Verflüssigerseite verdampfen. Geräte, deren Verflüssiger durch Belüftung und durch Verdampfung von zusätzlichem, von außen zuge-führtem Wasser abgekühlt wird, werden in dieser Norm nicht behandelt. Diese Norm gilt nicht für Geräte, bei denen, z. B. mit CO2 als Kältemittel, der Kreisprozess transzyklisch be-trieben wird. Anlagen für die Beheizung und/oder Kühlung industrieller Prozesse fallen nicht in den Anwendungsbereich dieser Norm.
