Abstract:
This air-handling system controls air volume according to the required air volume, which changes as needed. An air supply fan unit (20) is provided separate from an air-handling unit (10), sends external air from the outside to the air-handling unit (10), and sends the external air treated at the air-handling unit (10) to the interior. An air exhaust fan unit (30) is provided separate from the air-handling unit (10), sends internal air from the interior to the air-handling unit (10), and sends the interior air treated at the air-handling unit (10) to the outside. A controller controls the rotational speed of a first fan on the basis of a first detection value from a first air volume detection unit and the rotational speed of a second fan on the basis of a second detection value from a second air volume detection unit.
