Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling - Part 4: Requirements

This part of EN 14511 specifies minimum requirements which ensure that air conditioners, heat pumps and liquid chilling packages with electrical driven compressors are fit for the use designated by the manufacturer when used for space heating and/or cooling.
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 cooling any 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.

Luftkonditionierer, Flüssigkeitskühlsätze und Wärmepumpen mit elektrisch angetriebenen Verdichtern für die Raumbeheizung und Kühlung - Teil 4: Anforderungen

Dieser Teil der EN 14511 legt Mindestanforderungen fest, durch die sichergestellt ist, dass Luftkonditionierer, Wärmepumpen und Flüssigkeitskühlsätze mit elektrisch angetriebenem Verdichter für den vom Hersteller vor-gesehenen Einsatzbereich geeignet sind, wenn sie für die Raumheizung und/oder -kühlung eingesetzt werden. Diese Europäische Norm gilt für fabrikmäßig zusammengebaute Geräte, die mit Luftkanalanschlüssen ver-sehen sein können. Diese Norm gilt für fabrikmäßig zusammengebaute Flüssigkeitskühlsätze, die mit eingebauten Verflüssigern oder mit getrennt angeordneten Verflüssigern betrieben werden. 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 unter den Anwendungsbereich dieser Norm. Geräte mit Ein- und Zweikanalsystemen 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. ANMERKUNG Die Prüfung der Geräte unter Teillastbedingungen ist in CEN/TS 14825 festgelegt.

Climatiseurs, groupes refroidisseurs de liquide et pompes à chaleur avec compresseur entraîné par moteur électrique pour le chauffage et la réfrigération des locaux - Partie 4: Exigences

La présente partie de l’EN 14511 spécifie les exigences minimales permettant d’assurer que des climatiseurs, des pompes à chaleur et des groupes refroidisseurs de liquide avec compresseur entraîné par moteur électrique sont aptes à l’emploi prévu par le fabricant lorsqu’ils sont utilisés pour le chauffage et/ou la réfrigération des locaux. La présente Norme européenne s’applique aux appareils fabriqués en usine qui peuvent être raccordés. La présente norme s’applique aux groupes refroidisseurs de liquide autonomes fabriqués en usine ou conçus pour être utilisés avec des condenseurs fournis séparément. La présente norme s’applique aux appareils fabriqués en usine de capacité fixe ou variable par tous moyens. La présente norme couvre les systèmes monoblocs, à deux éléments séparés et multi-split. La présente norme couvre les appareils à simple et à double raccordement. Dans le cas d’appareils à éléments séparés, la présente norme ne s’applique qu’aux appareils conçus et fournis comme un ensemble, sauf pour ce qui concerne les groupes refroidisseurs de liquide avec condenseur séparé. La présente norme est principalement destinée aux groupes refroidisseurs d’eau et d’eau glycolée mais peut être utilisée, après accord, pour d’autres liquides. La présente norme s’applique aux climatiseurs air/air qui évaporent les condensats du côté condenseur. La présente norme ne couvre pas les appareils ayant leur condenseur refroidi par air et par évaporation d’eau d’un circuit supplémentaire externe. La présente norme ne couvre pas les appareils utilisant des cycles transcritiques, par exemple avec CO2 comme fluide frigorigène. La présente norme ne s’applique pas aux installations utilisées pour le chauffage et/ou le refroidissement des procédés industriels. NOTE Les essais à charge partielle des appareils sont traités dans la CEN/TS 14825.
