4. Show of Centrifugal fan
The two-outlet channels of Centrifugal fan are termed channels 1 and 2. There are no conclusive differences in the measured data for either channel. The designations 1 and 2 only show which channel is throttled and where the pressure measurements are made.
Variation of total pressure in channel 1 versus flow rate at each channel. Variations in the total pressure of both channels are fairly similar. It does not make any difference which of the two outlet channels has a constant throttle point when the other is throttled. Pressure in the fixed throttled channel remains constant when the other channel is throttled. This is important since it shows that if application setting in one channel changes, the users of the other channel will not experience higher or lower heads.
