본 발명은 냉/난방 겸용 공기조화기의 운전 제어방법에 관한 것으로, 특히, 난방 과부하시 실내배관온도를 검출하고, 상기 검출된 값에 따라 압축기를 동작시키는 운전 주파수를 다단계적으로 가변시키므로써, 싸이클 언매칭(CYCLE UNMATCHING)에 의한 총합전류의 상승이나 직류 전압의 피크(PEAK) 발생을 방지시켜, 공기조화기를 안정되게 동작시키기 위한 “공기조화기의 난방 과부하시 압축기 제어방법”에 관한 것이다. 일반적으로 실내기와 실외기로 구분되는 냉/난방 겸용 공기조화기는 냉각싸이클, 또는 난방싸이클을 통해 발생되는 냉/난기를 제어수단에 설정된 프로그램에 따라 부하를 제어하여 실내를 쾌적한 온도대로 유지하는 장치이다. 그러나, 상기와 같이 동작하는 공기조화기에 있어서는, 난방 과부화시 실내배관온도가 과도하게 상승하게 되면, 압축기의 동작을 제어하는 싸이클이 언매칭되게되고, 이로인해 총합전류가 증가하게 된다는 문제점 및 직류 피크전압이 발생하여 공기조화기의 동작이 불안정하게 된다는 문제점이 있었다.The present invention relates to an operation control method for a combined air / cooling air conditioner, and in particular, by detecting an indoor piping temperature when heating is overloaded, and varying an operation frequency for operating a compressor according to the detected value in multiple stages. The present invention relates to a "control method of a compressor in heating overload of an air conditioner" for preventing an increase in the total current due to cycle unmatching and a peak of a direct current voltage (PEAK) to operate the air conditioner stably. In general, a combined air / cooling air conditioner that is divided into an indoor unit and an outdoor unit is a device that maintains a room at a comfortable temperature by controlling a load according to a program set in a control unit through a cooling cycle or a heating cycle. However, in the air conditioner operating as described above, if the indoor piping temperature rises excessively during heating overload, the cycle controlling the operation of the compressor is unmatched, and thus the total current increases and thus the DC peak. There was a problem that the operation of the air conditioner unstable due to the voltage is generated.
