Description
본 발명은 냉난방 겸용 에어컨의 제상장치에 관한 것으로, 보다 상세하게는 겨울철 실외열교환기의 베이스에 착상되는 성에를 제거하기 위해 에어컨의 사방변과 가스관측 전자팽창밸브 사이에 흐르는 핫 가스가 실외열교환기 베이스를 지나도록 제상관을 형성시키고 실외열교환기의 코일온도에 따라 제상운전 여부를 판단하여 핫 가스가 제상관에 공급되도록 함으로써 제상 운전을 수행하는 냉난방 겸용 에어컨의 제상장치에 관한 것이다.The present invention relates to a defrosting device of a combined air-conditioning and air conditioner, and more particularly, in order to remove frost that forms on the base of an outdoor heat exchanger in winter, hot gas flowing between the four sides of the air conditioner and the gas-side electromagnetic expansion valve flows into the outdoor heat exchanger. It relates to a defrosting apparatus of a combined air-conditioning and air conditioning that forms a defrost pipe passing through the base and determines whether or not the defrost operation according to the coil temperature of the outdoor heat exchanger so that hot gas is supplied to the defrost pipe.
일반적으로 에어컨은 액체가 증발할 때 주위의 열을 흡수하는 현상을 이용하여 냉방작용을 하는 것으로서 이러한 냉방작용 이외에도, 제습작용을 함께 수행한다. 그런데, 냉난방 겸용 에어컨의 경우 냉방과 난방의 경우 냉매의 순환경로를 반대로 하여 난방운전시에는 실외의 열을 흡수하여 실내로 방출하게 되고, 냉방운전시에는 실내의 열을 흡수하여 실외로 방출하게 된다.In general, the air conditioner uses the phenomenon of absorbing the heat of the surroundings when the liquid evaporates, thereby cooling. In addition to the cooling, the air conditioner also performs dehumidification. By the way, in the case of air-conditioning combined air-conditioning and cooling and heating, the circulation path of the refrigerant is reversed so that the heat is absorbed and released into the room during the heating operation, and the heat is absorbed and released into the outdoor during the cooling operation. .
이러한 냉난방 겸용 에어컨은 난방운전시 실외열교환기에서 주위의 열을 흡수하는 증발과정시 실외열교환기 코일에 성에가 착상되기 때문에 이를 제거하기 위해 착상이 어느정도 진행되면 역싸이클을 이용해서 실외열교환기의 얼음을 제거한다.Since the air conditioner combined with heating and cooling is frosted on the outdoor heat exchanger coil during the evaporation process that absorbs the ambient heat from the outdoor heat exchanger during heating operation, if the conception is progressed to some extent to remove it, the ice of the outdoor heat exchanger is reversed. Remove it.
이를 제상 운전이라 하는데 겨울철 난방 운전시 제상 운전을 반복하다 보면 실외열교환기에서 녹은 물이 실외기 바닥면에 고여 어는 현상이 발생하고 시간이 지남에 따라 얼음이 계속 성장해 실외열교환기와 팬 부위 이상까지 자라나 팬 파괴와 난방 성능의 저하를 유발하는 문제점이 있다.This is called defrosting. If you repeat the defrosting operation during winter heating operation, the melted water in the outdoor heat exchanger will accumulate on the floor of the outdoor unit, and the ice will continue to grow over time, causing the fan to grow beyond the outdoor heat exchanger and the fan. There is a problem that causes destruction and deterioration of heating performance.
종래에는 이와 같은 문제점을 해소하기 위해 실외열교환기의 베이스에 열선을 구비하고 성에가 착상되는 시점에서 열선에 전원을 공급하여 제상을 수행하도록 하였다.Conventionally, in order to solve such a problem, the base of the outdoor heat exchanger is provided with a heating wire and defrosting is performed by supplying power to the heating wire when the frost is implanted.
그러나, 열선에 전원을 공급하는 방법은 누전의 염려가 있고 이로 인해 부품의 수명단축을 가져오는 문제점이 있다.However, the method of supplying power to the hot wire has a problem of short circuit, which causes a shortening of the life of the component.
