A mixed gas refrigerant for use as a replacement for CFC refrigerants, and specifically, for R-12, which includes at least three components including R-134a, R-124, and n-butane, with the n-butane being at least present in trace amounts and specifically between 1% and up to 4%.

Mixed gas R-12 refrigeration apparatus

A mixed gas refrigerant for use in the cryogenic range of temperatures between 80.degree. K. and 100.degree. K., with single stage compressor providing high pressures up to 30 Arms. The refrigerant consists of nitrogen between 30 and 50 molar percent, methane less than 20 molar percent, propane, more than 30 molar percent, and ethane the balance.

Cryogenic mixed gas refrigerant for operation within temperature ranges

A mixed gas refrigerant for use as a replacement for CFC refrigerants, and specifically, for R-12, which includes at least three components including R-134a, R-124, and n-butane.
