Refrigerant compressors - Rating conditions, tolerances and presentation of manufacturer's performance data; German version EN 12900:2013
Kältemittel-Verdichter - Nennbedingungen, Toleranzen und Darstellung von Leistungsdaten des Herstellers; Deutsche Fassung EN 12900:2013
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 fluid subcooling. This is required so that a comparison of different refrigerant compressors can be made. The data relate to the refrigerating capacity and power absorbed and includes requirements for part-load operation where applicable. This document (EN 12900:2013) has been prepared by Technical Committee CEN/TC 113 "Heat pumps and air conditioning units", the secretariat of which is held by AENOR (Spain).
