Three common reasons for poor performance of centrifugal fan systems are:
One is the improper connection of the outlet; the other is the uneven airflow at the inlet; the second is the eddy current generated at the inlet of the fan.
These conditions change the aerodynamic properties of high pressure centrifugal fans so that they cannot play their aerodynamic role. These conditions will occur if the connection at the inlet and outlet of the extractor fan is improperly designed or installed. A poor connection at the outlet will reduce the performance of the fan well below the ratings described in the fan catalog.
Other main reasons for poor performance are as follows:
The air performance characteristic curve of the actual pipe network system is quite different from the calculated curve of the pipe network system; the system design calculation does not leave some allowance for the effect of accessories and auxiliary equipment (that is, the additional resistance of the system), or the centrifugal fan is not selected. Consider the influence of auxiliary equipment on the performance of the fan; the performance of the system is determined by on-site measurement technology, and inaccurate results will be obtained due to measurement errors.
