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.
