Zusammenfassung:	FIELD: cooling agents. SUBSTANCE: invention relates to a mixed gaseous cooling agent. Refrigerant composition consists of a mixture of the following components, mole%: tetrafluoroethane (R-134a), 43-83; monochlorotetrafluoroethane (R-124), 10-15; n-butane, 4-11. Composition can contain additionally: SF6, R-125, propane, R-218, R-318, R-123, R-142b, R-152a. Method involves compressing and condensation of a refrigerant composition. EFFECT: composition exhibits ecological harmless, nontoxicity, high cooling coefficient and can substitute chlorofluorohydrocarbon refrigerants. 6 cl, 4 dwg, 4 exd
