【Abstract】 Shortcomings of traditional method to test supply air rate of outlet of ductwork are pointed out. A new testing method is put forward. The way to design the testing device based on this method is presented. The characteristics of the new method are analyzed. The testing device is convenient to operate, has higher accuracy in testing, and doesn’t need to be calibrated. It can be used both in laboratory and practical site testing.更多还原
