Dichlorodifluoromethane (CC12F2) and 1,1,1,2-tetrafluoroethane (CF3CH2F), in certain proportions, form an azeotrope and essentially azeotropic mixtures, which are constant boiling, or essentially constant boiling, and which mixtures possess refrigeration capacities higher than either of the CC12F2 and CF3CH2F components alone. These mixtures are especially adapted for use in systems having high-condensing temperatures such as automobile air conditioning systems. |
