(Main)Refrigerant compressors - Rating conditions, tolerances and presentation of performance data
Refrigerant compressors - Rating conditions, tolerances and presentation of performance data
This document specifies the rating conditions, tolerances and the method of presenting performance data of refrigerant compressors.
This document is applicable to single stage compressor and two stage compressor data with or without an additional intermediate pressure inlet.
The performance data of compressors used with R-744 in transcritical operation are covered in this document.
The data relating to the refrigerating capacity, heating capacity and power absorbed include requirements for part load operation where applicable. Presenting performance in this way enables a comparison of different compressors.
Kältemittel-Verdichter - Nennbedingungen, Toleranzen und Darstellung von Leistungsdaten
Dieses Dokument legt die Nennbedingungen, Toleranzen und die Darstellung der Leistungsdaten von Kältemittel-Verdichtern fest.
Dieses Dokument gilt für Daten von einstufigen und zweistufigen Verdichter mit oder ohne zusätzlichen Mitteldruck-Eintritt.
Die Leistungsdaten von Verdichtern, bei denen R 744 im transkritischen Betrieb zur Anwendung kommt, werden von diesem Dokument abgedeckt.
Die Daten beziehen sich auf die Kälteleistung, die Heizleistung und die Leistungsaufnahme und schließen den Teillastbetrieb ein, sofern zutreffend. Diese Darstellung der Leistung ermöglicht den Vergleich verschiedener Verdichter.
Compresseurs pour fluides frigorigènes - Détermination des caractéristiques, tolérances et présentation des données de performance
Le présent document spécifie les conditions de détermination des caractéristiques, les tolérances et le mode de présentation des données de performance, applicables aux compresseurs pour fluides frigorigènes.
Le présent document s’applique aux données de compresseurs mono-étagés et aux compresseurs bi-étagés, avec ou sans entrée de pression intermédiaire supplémentaire.
Les données de performance des compresseurs utilisés avec du R-744 en fonctionnement transcritique sont couvertes dans le présent document.
Les données relatives à la puissance frigorifique, à la puissance calorifique et à la puissance absorbée comprennent les exigences relatives au fonctionnement en charge partielle, quand cela est applicable. Cette manière de présenter les performances permet la comparaison de différents compresseurs.
