Abstract

본 발명은 에어콘의 냉매주입 조절방법에 관한 것으로, 종래에는 에어콘에 필요한 냉매를 메니폴다 게이지를 이용하여 냉매통에서 적당한 압력으로 현재 냉매를 주입하고 있으나 냉매는 기후와 온도조건에 따라 압력에 큰 변화를 보이는데 기후와 온도조건을 정확히 고려하지 않고 메니폴다 게이지로써 적당히 냉매를 주입함으로써 항상 냉매의 과도 또는 부족 현상을 발생한다. 이 냉매의 과도 또는 부족 현상은 에어콘의 냉방 싸이클에 불량을 가져오며, 냉방능력을 낼 수 없어 불량의 주요한 원인이 되는 등의 문제점이 있다.The present invention relates to a method for controlling the refrigerant injection of an air conditioner, but conventionally the refrigerant required for the air conditioner using the manifold gauge to inject the refrigerant at a suitable pressure in the refrigerant container at present, but the refrigerant changes significantly in pressure depending on the climate and temperature conditions. It does not consider the climate and temperature conditions accurately, but by injecting the refrigerant appropriately with the manifold gauge, the transient or shortage of the refrigerant always occurs. Excessive or shortage of the refrigerant causes a problem in the cooling cycle of the air conditioner, there is a problem such that the cooling ability can not be produced is the main cause of the failure.

따라서, 본 발명은 온도센서를 이용하여 증발기의 온도상태를 파악하고 그 파악한 온도에 따른 냉매압에 도달할 때까지 압력센서를 이용하여 냉매를 정확히 주입함으로써 효율적인 냉방을 실현하고, 불량이 적도록 한다.Therefore, the present invention uses the temperature sensor to determine the temperature state of the evaporator, and by accurately injecting the refrigerant by using the pressure sensor until the refrigerant pressure according to the determined temperature is reached to achieve efficient cooling and less defects .
