Scope

This document describes the test method for the performance of forced air-cooled refrigerant condensers.
This document is applicable to forced air-cooled refrigerant condensers/gas coolers that exchange heat with air on one side and refrigerant that undergoes phase change or is cooled on the other side, without air ducts.
This document is not applicable to refrigerant condensers/gas coolers connected to air ducts.
This document is not applicable to complete products mainly installed in machine rooms and pre-assembled condensing units/gas cooling unit assemblies in factories.
This document is not applicable to condensers with supercoolers.
