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的应用。本文分析了某种半封闭活塞式压缩机组和某种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。
Semi-hermetic reciprocating refrigeration compressors and fully enclosed rolling-rotor refrigeration compressors have been widely used for their distinctive features. This paper analyzes the characteristics of a semi-hermetic reciprocating compressor unit and a totally enclosed rolling-rotor compressor unit, and compares the cooling capacity, input power and COP at different evaporating temperatures, laying the foundation for practical application.
