ENVIRONMENTALLY SAFER REPLACEMENT REFRIGERANT FOR FREON 12-BASED REFRIGERATION SYSTEMS |
摘要 |
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 lubricating oil which is compatible with both the substitute refrigerant and with dichlorodifluoromethane.
