低温全封闭滚动转子式和半封闭活塞式制冷压缩机组的性能比较

Performance Comparing on Rolling Piston Type Rotary Compressor And Reciprocal Type Compressor in Low Temperature

半封闭活塞式制冷压缩机组和全封闭滚动转子式制冷压缩机组以其各自鲜明的特点得到了广泛应用。分析了三洋半封闭活塞式压缩机组和三洋全封闭滚动转子式压缩机组的特点,对比了不同蒸发温度下的制冷量和输入功率及COP值,为实际应用打下了基础。

The rolling piston type rotary and reciprocal type compressors each has notable characteristic so they have been gained widespread application.In the paper,the characteristic for compressors of reciprocal type and rolling piston type rotary has been analyzed,and the performance at the variable work condition has been compared,which has built a base for their application.
