More Information
Summary:The present invention relates to an air volume control system of a fan filter unit, which comprises: an upper chamber, an upper chamber, a lower chamber, an air path section, a temperature control module, a fan filter unit, a grating, and a control unit. A pressure difference measuring sensor is installed. The control unit includes a calculation module which receives a pressure measurement value from each fan filter unit and a rotary speed value of a driving motor, and makes the rotary speed control module control the rotary speed of a fan. The present invention is able to control the RPM of the fan filter unit to respond to a real-time pressure inside the actual fan filter unit, to reduce unnecessary power consumption, to greatly reduce operation costs, to efficiently maintain and manage the differential pressure, to discover a fan filter unit with a disorder in the early stage, and to minimize the defective quality of products which may occur when the balance of indoor air conditioning is disturbed by a disorder in the fan filter unit. 본 발명은 상부 챔버와, 하부 챔버와, 풍도 구간과, 온도 제어 모듈과, 팬 필터 유닛과 그레이팅 및, 제어부로 구성되되, 압력차 측정 센서가 설치되고, 상기 제어부는 각 팬 필터 유닛으로부터 수신되는 압력 측정값과 구동 모터의 회전 속도 값을 수신 받아 상기 회전속도제어모듈로 하여금 팬의 회전 속도를 조절시키는 연산모듈을 포함함으로써, 팬 필터 유닛의 RPM을 실제 팬 필터 유닛 내부의 실시간 압력에 대응될 수 있게 조절시킴으로써 불필요한 전력 소모를 줄여서 운영비용의 대폭 절감 및 효율적인 차압 유지 관리가 가능하고, 또한 이상이 발생된 팬 필터 유닛을 조기에 발견함으로써 팬 필터 유닛 이상으로 인한 실내 공기 조화의 균형이 교란되면서 발생될 수 있는 제품의 품질 불량을 최소화시킬 수 있는 팬 필터 유닛의 풍량 제어 시스템과 팬 필터 유닛의 풍량 제어 및 결함 예측 방법을 제공하고자 한다.
