Compressors and condensing units for refrigeration - Performance testing and test methods - Part 1: Refrigerant compressors
This part 1 of the European Standard applies only to refrigerant compressors and describes a number of selected performance test methods. These methods provide sufficiently accurate results for the determination of the refrigerating capacity, power absorbed, refrigerant mass flow, isentropic efficiency and the coefficient of performance. This standard applies only to performance tests conducted at the manufacturer's works or wherever the equipment for testing to the accuracy required is available. The type of measuring instrument and the limits within which measurements shall be made are listed in normative annex A.
Kältemittel-Verdichter und Verflüssigungssätze für die Kälteanwendung - Leistungsprüfung und Prüfverfahren - Teil 1: Kältemittel-Verdichter
Dieser Teil der Europäischen Norm gilt nur für Kältemittel-Verdichter und beschreibt eine Reihe von ausgewählten Leistungsprüfverfahren. Diese Verfahren ermöglichen ausreichend genaue Ergebnisse zur Bestimmung von
Kälteleistung, Leistungsaufnahme, Kältemittelmassenstrom, Gütegrad und Leistungszahl.
Diese Europäische Norm gilt nur für Leistungsprüfungen, die beim Hersteller durchgeführt werden oder wo die Einrichtung für eine Prüfung mit der erforderlichen Genauigkeit vorhanden ist.
Die Art der Messinstrumente und die Grenzen, in denen die Messungen durchgeführt werden müssen, sind in dem normativen Anhang A aufgeführt.
Compresseurs et unités de condensation pour la réfrigération - Essais de performances et méthodes d'essai - Partie 1: Compresseurs pour fluides frigorigènes
La présente partie de la norme européenne s'applique uniquement aux compresseurs pour fluides frigorigènes et décrit des méthodes d'essai des performances choisies. Ces méthodes fournissent des résultats suffisamment précis pour la détermination de la puissance frigorifique, de la puissance absorbée, du débit masse du fluide frigorigène, du rendement isentropique et du coefficient de performance.
La présente norme s'applique uniquement aux essais de performance réalisés dans l'usine du fabricant ou partout où l'équipement d'essai est disponible avec la précision requise.
Les types d'appareils de mesure et les incertitudes admissibles dans lesquelles les mesures doivent être réalisées sont donnés à l'annexe A.
