Abstract
An anomaly determination system includes inlet and outlet pressure sensors for a pressure loss portion, an outside pressure sensor, and an anomaly determination section for determining an anomaly of the pressure loss portion. The anomaly determination section determines that the pressure loss portion is anomalous if the following two conditions are both met: a difference between the inlet pressure and the outlet pressure, a difference between the outlet pressure and the outside pressure, and a difference between the outside pressure and the inlet pressure which differences are detected when the flow rate is less than the minimum flow rate are all included in an allowable range; and a pressure difference between the inlet pressure and the outlet pressure when the flow rate is greater than or equal to the minimum flow rate is included in the first pressure loss range.
