BS EN 13215:2016EN 13215:2016 (E) 5 1 Scope This European Standard specifies the rating conditions, tolerances and presentation of manufacturers performance data for condensing units for refrigeration with compressors of
25、 the positive-displacement type. These include single stage compressors and single and two stage compressors having an integrated means of fluid sub cooling. This is required so that a comparison of different condensing units can be made. The data relate to the refrigerating capacity and power absor
26、bed and include requirements for part-load performance where applicable. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
