Abstract

The present invention relates to a cooling agent composition that may be used in domestic or industrial cooling equipment as well as in cooling equipment for shops. This composition comprises the following components: from 45 to 80 vol. % of difluorochloromethane (R-22); from 15 to 50 vol. % of fluorodichloromethane (R-21); and from 0.1 to 25 vol. % of propane, butane, isobutane or one fluoroalkyl compound selected from the group comprising difluoromethane, difluoroethane, trifluoroethane, tetrafluoroethane, hexafluoropropane, heptafluoropropane and octafluorocyclobutane. This composition is compatible with the contemporary standards about the environment and fire prevention. This composition is not flammable, non-toxic, has a reduced ozone-destruction activity and can be easily mixed with mineral, synthetic or paraffin-based compressor oils. This composition may be used for the retrofit of difluorodichloromethane (khladon 12, R-12) in operating cooling equipment.

During the tests, the pressure on the compressor discharge lines, temperature in various units, energy efficiency, and efficiency of the cooling time were measured. Before filling the refrigerant with refrigerant 12 or a refrigerant composition of a given composition The unit was evacuated to a residual pressure of 5+10 mm Hg, kept under vacuum for 25-30 minutes, after which it was filled with a dose of the refrigerant under study. The cooler charge in all cases was taken from the liquid phase to avoid changes in the composition of the non-azeotropic mixture, the dose The reserve consisted of 80-Ю07<> from the technical documentation required for each compressor. The duration of testing on each unit was not less than 500 hours. The compressor tests were carried out at room temperature of 20 or in thermal chamber at 25-30°C.
