Abstract

본 발명은 에어콘의 제상 제어방법에 관한 것으로 운전율 및 신뢰성을 향상시키기 위한 것이다.The present invention relates to a defrosting control method of the air conditioner to improve the operation rate and reliability.

종래에는 상식선의 원리를 이용하여 실외온도와 배관온도가 낮을수록 제상 개시시간을 빨리하였다.Conventionally, the lower the outdoor temperature and the pipe temperature by using the common sense principle, the faster the defrosting start time.

따라서, 실외기에 히터를 사용하거나 한냉지형 에어콘에는 적용할 수 없고, -0℃ 이하에서는 90분에 제상되므로 운전율 및 신뢰성이 저하되었다.Therefore, it is not applicable to a heater in an outdoor unit or to a cold-cooled air conditioner, and defrosted at 90 minutes below −0 ° C., resulting in low operation rate and reliability.

본 발명은 실외온도와 배관온도차를 이용하여 배관온도가 3℃이고 압축기가 동작상태로 30분 이상 시간이 경과된 후 실외온도와 배관온도차가 설정치 이하이면 제상을 실시하도록 한 것이다.The present invention is to defrost if the pipe temperature is 3 ℃ by using the outdoor temperature and the pipe temperature difference and the outdoor temperature and the pipe temperature difference is less than the set value after 30 minutes or more elapsed in the operating state of the compressor.

따라서 -0℃ 이하에서도 제상을 정확하게 할 수 있으며 실외온도 설정차는 가열하여 결빙정도에 따라 제상할 수 있어 에어콘의 운전율 및 신뢰성을 향상시킬 수 있다.Therefore, defrosting can be done accurately even below -0 ℃, and the outdoor temperature set difference can be defrosted according to the degree of freezing by heating to improve the operation rate and reliability of the air conditioner.
