Abstract

본 발명은 냉난방 에어콘의 난방 운전중에 제상운전을 수행시키는 제상운전 제어방법에 관한 것으로 종래의 냉난방 에어콘에 있어서 난방운저이 지속되는 동안 실외에 설치된 실외기 주변의 온도가 영하의 농도로 낮아지면 실외기의 응축기(열교환기)가 열방출을 하지 못하고 주위의 낮은 온도로 인하여 열을 흡수하는 역효과가 생기고 이에따라 난방효율의 저하 및 압축기에 무리가 가해지게 될 뿐만아니라 응축기가 동결되어 파손되는 등의 문제점을 해결하기 위한 것이다.The present invention relates to a defrosting operation control method for performing a defrosting operation during a heating operation of an air conditioning air conditioner. In a conventional air conditioning air conditioner, when the temperature around the outdoor unit installed in the outdoor while the heating cooler continues is lowered to below zero concentration, the condenser of the outdoor unit (Heat exchanger) does not release heat and has the adverse effect of absorbing heat due to the low temperature of the surroundings, thereby reducing the heating efficiency and overpressing the compressor, as well as solving problems such as condenser freezing and damage. It is for.

본 발명은 온도감지 수단으로 실외온도를 감지하여 실외온도가 일정온도 이하가 되거나 또는 일정시간 동안 난방운정을 수행한 후에 마이컴이 사방변을 제어하여 냉방운정을 시켜 실외기의 응축기를 가온시켜 주므로서 난방효율의 저하 및 응축기 동파를 방지하고 압축기를 과부하로 부터 보호할 수 있도록 한 것으로 냉난방 에어콘에 적용한다.The present invention senses the outdoor temperature by the temperature sensing means, after the outdoor temperature is below a certain temperature or after the heating operation for a predetermined time, the microcomputer controls the four sides to cool the operation by heating the condenser of the outdoor unit heating It is applied to heating and cooling air conditioner to prevent efficiency deterioration and condenser freeze protection and to protect the compressor from overload.

Claims

In the first process of determining whether the detected outdoor temperature is the defrosting operation temperature (-X ° C) while performing the heating operation, and if the determination result is higher than or equal to the defrosting operation temperature (-X ° C), the heating operation is continued and if it is below, the defrosting operation is performed. When the outdoor temperature is the return temperature (X ° C) or the predetermined time (t) has elapsed, the second process of performing the heating operation, and then the heating time (T) or the detected outdoor temperature during the heating operation is the defrosting operation temperature. (-X ℃) the defrosting operation control method of the heating and cooling air conditioning consisting of a third process of performing the defrosting operation by stopping the four sides and the fan.
