摘要：
Refrigerant mixtures used in the lower temperature stage of two-stage cascade refrigeration systems and obtained by physical mixing of ethane, hexafluoroethane, or/and trifluoromethane. One of the refrigerant mixtures comprises ethane and hexafluoroethane. Another refrigerant mixture comprises ethane and trifluoromethane. Yet another one of the refrigerant mixtures comprises ethane, hexafluoroethane, and trifluoromethane.
