Abstract

본 발명은 공기조화기에 있어서, 열교환된 저온저압의 기체냉매를 고온고압의 기체냉매로 변환시키는 압축기의 입력전류상태를 전류 검지부로 검지하고, 이 검지된 전류와 현재 주위환경변화에 따른 조건하에서 흘려야 할정격전류와의 비교차를 산출하여 그 전류가 하한전류치이하인 경우 압축기의 냉매량이 누설되어 있음을 표시할 수 있도록 함으로써 압축기의 냉매누설로 인하여 야기될 수 있는 제반 문제점을 해소할 수 있도록 한 것임.In the air conditioner, the current detection unit detects an input current state of a compressor for converting a heat-exchanged low-temperature low-pressure gas refrigerant into a high-temperature high-pressure gas refrigerant, and flows under a condition according to the detected current and the current ambient environment change. It is possible to solve all the problems that may be caused by the refrigerant leakage of the compressor by calculating the difference between the rated current and indicating that the refrigerant amount of the compressor is leaked when the current is lower than the lower limit current value.
