Abstract
A problem to be solved by the present disclosure is to enhance the reliability of determination of occurrence or non-occurrence of surging. Whether or not surging occurs depends on front-rear differential pressure. Therefore, by determining occurrence or non-occurrence of surging on the basis of the front-rear differential pressure, a second unit can detect and avoid surging with higher accuracy than when determining by using the pressure on an outlet side of a second fan.
