电风扇能效值的工程计算方法

Abstract

Abstract: For a long time, it is difficult for manufacturers to obtain approximate values of energy efficiency of electric fan during the design and development stage. An engineering calculation method is presented in this paper. By establishing the correlation curve of fan blade, and by comparing with the motor characteristic curve, this method can find out the normal work point of the fan, so the approximate value of energy efficiency can be calculated.

Key words: Energy efficiency, Engineering calculation methods, Characteristic curve of blades, Characteristic curve of motor
