1.1 The scope of EN 14511 1 is applicable. 1.2 This European Standard specifies the test conditions for the rating of air conditioners, liquid chilling packages and heat pumps, using either, air, water or brine as heat transfer media, with electrically driven compressors when used for space heating and/or cooling. The standard also specifies the test conditions for the rating of air-cooled and water(brine)-cooled process chillers. 1.3 This European Standard specifies the conditions for which performance data is to be declared for single duct and double duct units for compliance to the Ecodesign Regulation 206/2012 and Energy Labelling Regulation 626/2011.

This European Standard specifies the terms and definitions for the rating and performance of air conditioners, liquid chilling packages and heat pumps using either air, water or brine as heat transfer media, with electrically driven compressors when used for space heating and/or cooling. It also specifies the terms and definitions for the rating and performance of process chillers. This European Standard does not apply to heat pumps for domestic hot water, although certain definitions can be applied to these. This European Standard applies to: - factory-made units that can be ducted, - factory-made liquid chilling packages with integral condensers or for use with remote condensers, - factory-made units of either fixed capacity or variable capacity by any means, and - air-to-air air conditioners which can also evaporate the condensate on the condenser side. Packaged units, single split and multisplit systems are covered by this standard. Single duct and double duct units are covered by

1.1 Es gilt der Anwendungsbereich von EN 14511-1. 1.2 Diese Europäische Norm legt die Prüfverfahren für die Bemessung und Leistung von Luftkondi-tionierern, Flüssigkeitskühlsätzen und Wärmepumpen, die Luft, Wasser oder Sole als Wärmeträger nutzen und mit elektrisch angetriebenen Verdichtern betrieben werden, für die Raumbeheizung und -kühlung fest. Diese Prüfverfahren gelten auch für die Bemessung und Leistung von Prozess-Kühlern. Sie legt weiterhin ein Verfahren zur Prüfung und Angabe von Wärmerückgewinnungsleistungen, systemreduzierten Leistungen sowie der Leistung von Einzelgeräten von Multi-Split-Systemen für die Aufstellung im Innenraum, soweit zutreffend, fest. Diese Europäische Norm bietet außerdem die Möglichkeit, die Leistung von Multi-Split-Systemen und modularen Multi-Split-Systemen mit Wärmerückgewinnung durch getrennte Leistungsbemessung von Geräten für die Aufstellung im Innenraum und Geräten für die Außenaufstellung (Innen- und Außengeräte) zu bemessen.

1.1 This Standard describes the calculation of mass flow for sizing pressure relief devices for components of refrigerating systems. NOTE The term "refrigerating system" used in this Standard includes heat pumps. 1.2 This Standard describes the calculation of discharge capacities for pressure relief valves and other pressure relief devices in refrigerating systems including the necessary data for sizing these when relieving to atmosphere or to components within the system at lower pressure. 1.3 This Standard specifies the requirements for selection of pressure relief devices to prevent excessive pressure due to internal and external heat sources, the sources of increasing pressure (e.g. compressor, heaters, etc.) and thermal expansion of trapped liquid. 1.4 This Standard describes the calculation of the pressure loss in the upstream and downstream line of pressure relief valves and other pressure relief devices and includes the necessary data. 1.5 This Standard refers to other relevant
