摘要

The method involves spraying cleaning water from inside the fan e.g. at intermittent intervals. The fan is mounted in a roof-shaped ventilator so that the water sprayed up through the cleaning process can be collected and discharged. The spray device (11) is mounted in the fan area so that its spray range reaches the radial fan (3) and/or diagonal fan.
