Abstract

The present invention relates to a refrigerant composition, in particular a mixed refrigerant composition with an ozone depletion potential (ODP) of 0 and a global warming potential (GWP) of 3, the refrigerant composition comprising 50 to 56 kg of hydrocarbon-based propane (R-290) and 40 to 49 kg of isobutane (R-600a) as a base, to which 2 to 5 kg of normal butane (R-600) and 1-3 kg of propylene (R-1270) are added, and 0.5 to 1 kg of hexamethyl silicone oil is added as an additive to form a near azeotrope.
