5、s chiller) 机组。 预旋转导流叶片安装在叶轮吸气口处，在伺服马达的驱动下，可以改变吸气流通面积和气流方向。其作用是：1、通过吸气流通面积的变化来改变进气量，满足外界负荷的变化；2、在部分负荷时，通过气体的预旋转，使气流具有一定的旋转动能，减小压缩功，提高效率。 与其他公司通过设置旁通或采用截流阀来降低制冷剂流量的方法相比，预导流叶片的调节效率更高。因此，从1996年至今，所有的离心机生产厂家都采用预导流叶片的方法调节制冷剂流量以适应负荷的变化。ap learning institute18全开ap learning institute19部分关闭ap learning institu
