Development of Swing Compressor for Alternative Refrigerants

摘要

In a rotary compressor, we must improve the durability of the lubrication for alternative refrigerants (hydrofluorocarbons), because by changing refrigerants there is a loss of lubricating ability. We have improved the durability by changing from rotary to swing structure, rather than by changing the material of the rotary compressor. This improvement of lubrication can reduce sludge generation, too, and therefore reduce capillary tube clogging. In addition, we have improved the energy performance by changing from rotary to swing structure. This paper presents the development of the swing compressor for alternative refrigerants and its experimental results.
