IMPELLER FOR COMPOUND MULTIBLADE BLOWER, COMPOUND MULTIBLADE BLOWER AND AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide an efficient compound multiblade blower.;SOLUTION: A plurality of impeller units 2 respectively formed of annually arranged plural blade members 5 and a pair of end ring members 4 for supporting both ends of the blade members are connected to each other in both sides of a spacer unit 3 in the rotary shaft direction. In a vane for compound multiblade blower with this structure, the impeller unit 2 is formed so that a ratio of the cross dimension Bf in the rotary shaft direction to the inner diameter D thereof satisfies the relation Bf≤1.6D.;COPYRIGHT: (C)2002,JPO
