  • Patent number: 11345840
    Abstract: An apparatus and method wherein potential ozone layer-damaging chlorodifluoromethane (Refrigerant R-22) is substituted with a mix of less environmentally damaging refrigerants pentafluoroethane and tetrafluoroethane in chlorodifluoromethane-based air-cooling systems mainly in residential cooling. While less environmentally damaging than chlorodifluoromethane, the substitute refrigerant has a temperature-pressure relationship similar to that of chlorodifluoromethane, making the substitute refrigerant suitable for use with chlorodifluoromethane-based air-cooling systems. In this event, it is mixed with a relatively small percentage of a lubricating oil which is compatible with both the unit refrigerant and typical R-22 system design.

  • Patent number: 7332102
    Abstract: An apparatus and method wherein potential ozone layer-damaging dichlorodifluoromethane (Refrigerant R-12) is substituted with a mix of less environmentally damaging refrigerants Chlorodifluoroethane and Tetrafluoroethane in dichlorodifluoromethane-based air-cooling systems, in particular HVAC and refrigeration applications. While less environmentally damaging than dichlorodifluoromethane, the substitute refrigerant is less flammable than presently available refrigerants, yet still has a temperature-pressure relationship close enough to that of dichlorodifluoromethane, making the substitute refrigerant suitable for use with dichlorodifluoromethane-based air-cooling systems. In this event, it is mixed with a lubricating oil that is compatible with both the unit refrigerant and typical R-12 system design.
