涡旋压缩机是一种容积式压缩的压缩机，压缩部件由动涡旋盘和静涡旋组成。其工作原理是利用动、静涡旋盘的相对公转运动形成封闭容积的连续变化，实现压缩气体的目的。主要用于空调、制冷、一般气体压缩以及用于汽车发动机增压器和真空泵等场合，可在很大范围内取代传统的中、小型往复式压缩机。
Scroll compressor is a kind of positive displacement compression compressor. The compression part is composed of moving scroll and static scroll. Its working principle is to use the relative revolution motion of the dynamic and static scroll to form a continuous change of the closed volume, so as to achieve the purpose of compressing gas. It is mainly used in air conditioning, refrigeration, general gas compression, automobile engine supercharger and vacuum pump. It can replace the traditional medium and small reciprocating compressor in a large range.
