Abstract

본 발명은 냉장고의 온도제어 시스템에 관한 것으로, 냉장실 또는 냉동실에 2개의 온도 감지센서를 구비시키고 또한 이 두개의 온도감지센서의 최고점과 최저점을 다르게 하여 냉장고의 온도를 제어하는 시스템으로서, 냉장고에 구비된 마이컴은 매 온도측정 주기마다 어느 하나의 온도측정값이 변화가 있었는지 판단하고, 온도의 상승이 있으면 다른 온도감지센서의 최저점까지 온도를 내리고, 온도의 하강이 있으면 다른 온도감지 센서의 최고점까지 온도를 올려 항상 일정한 냉각온도를 제공하는 것을 특징으로 함.The present invention relates to a temperature control system of a refrigerator, comprising two temperature sensors in a refrigerating or freezing chamber, and controlling the temperature of the refrigerator by changing the highest and lowest points of the two temperature sensors, which is provided in the refrigerator. The microcomputer judges which temperature measurement value has changed at every temperature measurement cycle, and if there is an increase in temperature, lowers the temperature to the lowest point of the other temperature sensor, and if there is a decrease in temperature, to the highest point of the other temperature sensor. Raise the temperature to provide a constant cooling temperature at all times.
