Air volume control system of fan filter unit and control/defect prediction method for fan filter unit

摘要

The present invention is composed of an upper chamber, a lower chamber, a wind section, a temperature control module, a fan filter unit, a grating, and a control unit, and a pressure difference measurement sensor is installed, and the control unit is received from each fan filter unit. By including a calculation module that receives the pressure measurement value and the rotational speed value of the drive motor and causes the rotational speed control module to adjust the rotational speed of the fan, the RPM of the fan filter unit may correspond to the real-time pressure inside the actual fan filter unit. It is possible to reduce unnecessary power consumption, thereby greatly reducing operating costs and maintaining efficient differential pressure. In addition, by early detection of the fan filter unit that has an abnormality, the balance of indoor air conditioning due to fan filter unit failure is disturbed. It is intended to provide a fan filter unit air volume control system and a fan filter unit air volume control and defect prediction method that can minimize product quality defects that may occur.
