  离心式风机的风量调节方式很多,有进、出口风阀调节,蜗线风阀调节,进口叶片调节,动翼调节,转数调节等方式。对于各种不同类型的风机,由于调节方式不同,所得的节能效果差别很大。

  2、进口叶片调节进口叶片调节,是通过调节叶片,使吸入叶轮的气流方向变化,改变风机的性能曲线。空调风机进口气流的正旋绕调节,可实现进口导叶角度为零度时性能曲线以下的全部工况;而进口气流的负旋绕调节,可提高风机的压力和流量,但调节范围有一定的限度。由于进口叶片调节具有较宽的调节范围和较高的经济性,并可实现自动调节,因此,为空调风机所广泛使用。进口叶片调节,前向多翼风机调节特性比后向板式或后向翼形风机好。虽然前向多翼风机单机效率比后向板式或后向翼形风机低,但在VAV系统,由于前向多翼风机功率降低特性好,两者所消耗的功率几乎一样,再加上前向多翼风机具有小型轻量转数低的优点,使它在VAV系统中应用更广泛。
