Refrigerator oil

Abstract

Abstract PURPOSE:To improve the lubricity in low-temp. starting and high degree of dissolution of a refrigerant, by mixing a particular alkylbenzene of hard type with a paraffinic mineral oil which has been dewaxed at low temperature so that the mixed oil exhibits particular properties. CONSTITUTION:An alkylbenzene of hard type having a viscosity of 40cst or more at 40 deg.C and a paraffinic oil which has been dewaxed at low temperature are mixed with each other so that the mixed oil has a critical dissolution temp. of -10 deg.C or below and a viscosity of 3cst or more as determined at 60 deg.C and 16kg/cm<2>abs in dissolution of R-22.
