Abstract

Gas viscosities of azeotropic mixtures R500 (dichlorodifluoromethane (R12)-1,1-dlfluoroethane (R152a)), R502 (chlorodlfluoromethane (R22)-chloropentafluoroethane (R115)), and R503 (chlorotrlfluoromethane (R13)-trifluoromethane (R23)) were measured with an oscillating disk viscometer of the Maxwell type at 273.15-423.15 K up to 7.5 MPa. Two empirical equations for the viscosities were obtained; one is for the atmospheric viscosities as a function of temperature, and the other is for the viscosities In the whole range of the present measurement as a function of temperature and density.
