  • Environmentally safer replacement refrigerant for Freon 12-based refrigeration systems
    Patent number: 6758987
    Abstract: An apparatus and method wherein ozone layer-damaging dichlorodifluoromethane is substituted with a mix of less environmentally damaging refrigerants chlorodifluoroethane and tetrafluoroethane in dichlorodifluoromethane-based air-cooling systems. While less environmentally damaging than dichlorodifluoromethane, the substitute refrigerant has a temperature-pressure relationship similar to that of dichlorodifluoromethane, making the substitute refrigerant suitable for use with dichlorodifluoromethane-based air-cooling systems. The substitute refrigerant can be used alone or in combination with dichlorodifluoromethane. In either event, it is mixed with a relatively small percentage of a hydrophobic lubricating oil which is compatible with both the substitute refrigerant and with dichlorodifluoromethane.
    Type: Grant

  • Environmentally safer replacement refrigerant for freon 12-based refrigeration systems
    Patent number: 5492643
    Abstract: An apparatus and method and refrigerant wherein ozone layer-damaging dichlorodifluoromethane is substituted with a mix of less environmentally damaging refrigerants chlorodifluoroethane and tetrafluoroethane in dichlorodifluoromethane-based air-cooling systems. While less environmentally damaging than dichlorodifluoromethane, the substitute refrigerant has a temperature-pressure relationship similar to that of dichlorodifluoromethane, making the substitute refrigerant suitable for use with dichlorodifluoromethane-based air-cooling systems. The refrigerant includes a lubricant which is compatible with dichlorodifluoromethane, chlorodifluoroethane and tetrafluoroethane.
