Abstract

본 발명은 중기 압축기 에어콘에 있어 냉매누설량을 예측하여 에어콘의 운전을 제어하여 줌으로서, 압축기의 과열로 인하여 발생되는 압축기의 소손을 방지하고자 한 냉매 누설 감지를 통한 에어콘의 운전 제어 방법에 관한 것이다.The present invention relates to a method of controlling an operation of an air conditioner by detecting a refrigerant leakage in order to prevent the compressor from being burned due to overheating of the compressor by controlling the operation of the air conditioner by predicting the refrigerant leakage amount in the middle-stage compressor air conditioner.

종래에는 냉매의 누설량이 많을 경우에는 압축기 과열방지 장치가 작동하여 압축기를 정지시켜 압축기의 과열을 방지하며, 이와같이 압축기를 정지시킨후 일정시간이 경과하게 되면, 다시 압축기를 동작시켜 냉방을 실행하게 되나, 냉매 누설량이 많을 경우에는 상기와 같이, 압축기의 동작과 정지를 반복하게 되면, 압축기 오일의 열화등으로 인하여 압축기가 소손되는 문제점이 발생하게 된다.Conventionally, when the amount of leakage of the refrigerant is large, the compressor overheating prevention device operates to prevent the compressor from overheating by stopping the compressor. When a certain time has elapsed after stopping the compressor in this way, the compressor is operated again to perform cooling If the refrigerant leakage amount is large, if the operation and stoppage of the compressor are repeated as described above, the compressor may be damaged due to deterioration of the compressor oil.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 증발 및 응축 온도와 압축기 토출 온도를 이용하여 냉매의 누설량을 감지하여 냉매의 누설량에 따라 압축기를 제어하여 줌으로서, 냉매의 누설량이 많아질 경우에 발생되는 압축기의 과열등으로 인한 소손을 방지할 수 있게 되는 것이다.SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a refrigeration cycle control apparatus and a refrigeration cycle control method for controlling a compressor according to a leakage amount of a refrigerant by detecting a leakage amount of refrigerant using evaporation and condensation temperature and compressor discharge temperature, It is possible to prevent the compressor from being burned out due to overheating or the like.
