Claims (5)
- 토출관의 현재 토출압력과 설정압력을 비교한 후 인버터 주파수를 가산 또는 감산하는 한편, 인버터의 출력주파수 레벨값을 비교하여 주펌프와 보조펌프의 운전과 정지를 제어하는 인버터 펌프의 압력 제어방법에 있어서,상기 토출관의 설정압력과 인버터 펌프 복귀압력편차의 차이가 토출관의 현재압력보다 클 때 가압식급수시스템을 오프 상태에서 온 상태로 변환하여 인버터 펌프를 구동시키는 단계;상기 토출관의 설정압력과 인버터 펌프 복귀압력편차의 차이가 토출관의 현재압력과 같을 때 가압식급수시스템을 온 상태로 유지시킨 후 인버터 펌프를 구동 복귀시키는 단계; 및,상기 토출관의 현재압력과 토출관의 설정압력이 같다면 인버터 펌프의 동작주파수를 상승 또는 감소시키지 않고 현재 상태로 유지시키는 단계; 를 더 포함하여 구성함을 특징으로 하는 인버터 펌프의 압력제어방법.
- 청구항 1에 있어서 상기 제 2 단계에서,상기 인버터펌프 복귀압력편차가 일정한 인버터 펌프의 압력 제어방법.
