Abstract

본 발명에 따른 공기조화기는 압축기와 응축기와 팽창기구와 증발기를 포함하고, 상기 증발기에 수배관이 연결되어 냉수를 공급하며, 수배관이 병렬로 연결된 복수개의 칠러를 포함하고, 복수개의 칠러 중 운전 중인 칠러는 고압측과 저압측의 차압에 따라 운전인 칠러의 냉수 설정온도를 설정함과 아울러 설정된 냉수 설정온도에 따라 압축기의 운전 용량을 조절하고, 차압이 설정시간동안 설정압력 이상이고 복수개의 칠러 중 현재 미운전인 칠러가 있으면 현재 미운전인 칠러에 운전 명령을 전송하는하여, 부하에 따른 효율적인 운전이 가능하고, 소비전력을 최소화할 수 있는 이점이 있다.
