    摘要: 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.

    摘要: A method for improving filterability, while maintaining or improving antifoaming performance, of a lubricating oil in an engine or other mechanical component lubricated with the lubricating oil by using as the lubricating oil a formulated oil. A method for improving antifoaming performance, while maintaining or improving filterability, of a lubricating oil in an engine or other mechanical component lubricated with the lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one antifoam agent, as a minor component. A lubricating oil having a composition including a lubricating oil base stock as a major component, and at least one antifoam agent, as a minor component. The antifoam agent is a silicone composition having a highly branched functionalized silicone backbone. The lubricating oils are useful as automotive gear lubricating compositions.

    摘要: A refrigeration apparatus includes a compressor, a first heat exchanger, an expansion mechanism, and a second heat exchanger. The compressor compresses low-pressure gas refrigerant and discharges high-pressure gas refrigerant. The first heat exchanger condenses high-pressure gas refrigerant and discharges high-pressure liquid refrigerant during an air-cooling operation, or evaporates low-pressure gas-liquid mixed refrigerant and discharges low-pressure gas refrigerant during an air-heating operation. The expansion mechanism has metal components. High-pressure liquid refrigerant passes through the expansion mechanism, and becomes low-pressure gas-liquid mixed refrigerant. The second heat exchanger evaporates low-pressure gas-liquid mixed refrigerant and discharges low-pressure gas refrigerant during an air-cooling operation, or condenses high-pressure gas refrigerant and discharges high-pressure liquid refrigerant during an air-heating operation. The refrigerant contains at least 60 wt % of R32. An acid scavenger added in an amount of 1.0 wt % to 5.0 wt % is blended in refrigerator oil for lubricating the compressor.
