    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 hydrophobic lubricating oil which is compatible with both the substitute refrigerant and with dichlorodifluoromethane.

    摘要翻译: 在基于二氯二氟甲烷的空气冷却系统中,用环境有害的制冷剂氯二氟乙烷和四氟乙烷的混合物替代臭氧层破坏性二氯二氟甲烷的装置和方法。 虽然与二氯二氟甲烷相比,环境破坏较小,但替代制冷剂具有与二氯二氟甲烷相似的温度压力关系,使得替代制冷剂适用于与二氯二氟甲烷基的空气冷却系统。 替代制冷剂可以单独使用或与二氯二氟甲烷组合使用。 在任一情况下,它与相对小百分比的疏水性润滑油混合,其与替代制冷剂和二氯二氟甲烷都相容。
