多级压缩机
摘要：
一种多级压缩机，作为工作气体而使用CO2，且能够大容量化。本发明的多级压缩机具备：密闭壳体、密闭壳体内设置的多个压缩机构、驱动多个压缩机构的电动机，多个压缩机构的至少一个是涡旋压缩机构，且把包含超临界状态的气体作为工作气体，其中，涡旋压缩机构具备：固定涡形部件，其在端板的一面侧形成螺旋状卷绕部；旋转涡形部件(116)，其在端板(117)的一面侧设置螺旋状卷绕部(118)且使卷绕部(118)与固定涡形部件的卷绕部组合而形成螺旋状压缩室，随着旋转涡形部件(116)的旋转而把导入的工作气体在压缩室内进行压缩，当把旋转涡形部件(116)的端板(117)的厚度设定为Worb、把旋转涡形部件(116)的卷绕部(118)的高度设定为L时，满足L≥Worb。
摘要（英）：

A large capacity compressor employing CO2 as working gas. The multistage compressor comprises an enclosed housing, a plurality of compression mechanisms provided in the enclosed housing, and a motor for driving the plurality of compression mechanisms wherein at least one compression mechanism is a scroll compression mechanism and gas including a supercritical state is employed as working gas. The scroll compression mechanism includes a fixed scroll having a spiral lap formed on one side of an end plate, and a turning scroll (116) provided, on one side of the end plate (117), with a spiral lap (118) which is combined with the lap of the fixed roll to form a spiral compression chamber. Working gas introduced into the compression chamber is compressed as the turning scroll (116) turns and following relation L>=Worb is satisfied between the thickness Worb of the end plate (117) of the turning scroll (116) and the height L of the lap (118) of the turning scroll (116).
