Abstract
Description
Claims (5)
- 실외기에 장착 구비된 압축기가 엔진에 의해 구동되고, 이 엔진의 냉각수를 냉각수 순환 펌프에서 방열기로 순환시켜 냉각하는 엔진 냉각 장치를 구비한 공기 조화 장치에 있어서,상기 냉각수 순환 펌프의 구동 전류를 검지하는 검지 수단과,이 검지치에 의거하여 냉각수 순환 펌프의 공기 혼입의 발생을 판정하는 판정 수단을 구비한 것을 특징으로 하는 공기 조화 장치.
- 제1항에 있어서, 상기 판정 수단은 상기 구동 전류의 검지치와 비교하는 기준치로서, 하한 기준치 및 상한 기준치 2개의 기준치를 갖는 것을 특징으로 하는 공기 조화 장치.
- 제2항에 있어서, 상기 판정 수단은 제1 회째의 구동 전류의 검지치가 하한 기준치 이하인 경우 바로 공기 혼입으로 판정하고, 상한 기준치 이상인 경우 오검지로 판정하고, 그 이외인 경우 구동 전류치를 복수회 카운트하여 평균치를 구하고, 이 평균치가 소정의 공기 혼입 판정치를 넘고 있는 경우 공기 혼입으로 판정하는 것을 특징으로 하는 공기 조화 장치.
- 제3항에 있어서, 공기 혼입으로 판정한 회수를 카운트하고, 이 카운트가 일 정 시간 내에 소정 회수에 이른 경우, 최종적으로 공기 혼입이 발생했다고 판정하는 것을 특징으로 하는 공기 조화 장치.
- 제1항 내지 제4항 중 어느 한 항에 있어서, 상기 냉각수 순환 펌프의 공기 혼입의 발생이 검출된 경우, 냉각수 부족의 메시지를 출력하는 것을 특징으로 하는 공기 조화 장치.
