What problems might arise from using two centrifugal fans in parallel?
Separate exit flow control is required, and the common exit must have sufficient flow capacity.
Does it mean that each one should be equipped with a valve to regulate the flow rate? Can they receive the same signal and adjust the air volume simultaneously through frequency conversion?
Generally, there should be no problems; the \"output\" balance is automatically achieved based on the air volume and pressure of the two fans.
It is best to adjust them synchronously to prevent large differences in airflow and pressure among multiple turbines, which can lead to wind competition and surge.
