27、Scope This European Standard specifies the rating conditions, tolerances and presentation of manufacturers performance data for condensing units for refrigeration with compressors of the positive-displacement type. These include single stage compressors and single and two stage compressors having an

28、 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 absorbed and include requirements for part-load performance where applicable. 2 Normative references The following document
