Refrigerant compressors - Rating conditions, tolerances and presentation of manufacturer's performance data
This European Standard specifies the rating conditions, tolerances and the method of presenting manufacturer's data for positive displacement refrigerant compressors. These include single stage compressors and single and two stage compressors using a means of liquid subcooling. This is required so that a comparison of different refrig-erant compressors can be made. The data related to the refrigerating capacity and power absorbed, include correc-tion factors and part-load performance where applicable.
Kältemittel-Verdichter - Nennbedingungen, Toleranzen und Darstellung von Leistungsdaten des Herstellers
Diese Europäische Norm legt die Nennbedingungen, Toleranzen und die Darstellung der Leistungsdaten des
Herstellers für Kältemittel-Verdichter des Verdrängertyps fest. Dazu gehören einstufige Verdichter und ein-
und zweistufige Verdichter mit Flüssigkeitsunterkühlung. Dies ist notwendig, damit ein Vergleich von unter-schiedlichen
Verdichtern durchgeführt werden kann. Die Daten beziehen sich auf die Kälteleistung und die
Leistungsaufnahme und schließen Korrekturfaktoren und Teillastleistungen ein, sofern zutreffend.
Compresseurs pour fluides frigorigènes - Conditions de détermination des caractéristiques, tolérances et présentation des performances du fabricant
La présente Norme Européenne spécifie les conditions de détermination des caractéristiques, les tolérances
et le mode de présentation des performances par le fabricant, applicables aux compresseurs volumétriques
pour fluides frigorigènes. Ceux-ci incluent les compresseurs mono-étage, les compresseurs mono-étage et
bi-étages avec sous-refroidissement liquide. La présente norme est nécessaire afin de permettre la
comparaison de différents compresseurs pour fluides frigorigènes. Les données relatives aux performances
se rapportent à la puissance frigorifique et à la puissance absorbée, et comprennent des facteurs de
correction ainsi que les performances en charge partielle, quand cela est applicable.
