Abstract

본 발명은 냉장고의 냉동실 온도조절 방법에 관한 것으로, 종래에는 기계식 냉장고에만 적용 가능한 기술로써 일정온도 기준의 써모스텟을 사용해야 하므로 냉동실 노트(NOT)내에 따라 제어가 불가능하며 항상 기준 온도가 일정하므로 자세한 제어가 불가능한 문제점이 있다. 따라서, 본 발명은 콤프레샤 오프시에도 냉동실 팬모터의 구동으로 증발기 주위와 냉동실간의 온도차를 줄이고, 그 온도차를 줄임으로 인해 콤프레샤의 운전율을 낮게함으로써 에너지의 효율 향상을 꾀할 수 있도록 하며, 전자식으로 냉장고를 제어할 수 있도록 한다.The present invention relates to a method of controlling a freezer compartment temperature of a refrigerator, and in the related art, a thermostat of a predetermined temperature standard must be used as a technology applicable only to a mechanical refrigerator. There is an impossible problem. Therefore, the present invention can reduce the temperature difference between the evaporator and the freezer compartment by driving the freezer fan motor even when the compressor is off, thereby lowering the operation rate of the compressor by reducing the temperature difference, thereby improving the energy efficiency, and electronically the refrigerator. To control.
