PURPOSE: A refrigerator and a control method of a circulating fan are provided to reduce the number of defrosting with a defrosting heater by defrosting naturally with the circulating fan and to save power by restricting increase of temperature in the refrigerator with the defrosting heater. CONSTITUTION: An evaporator is installed to a refrigerating room side to cool a refrigerating room. A circulating fan circulates air of the refrigerating room and a rotating motor rotates the circulating fan. A temperature sensor(401) senses temperature of the refrigerating room. A defrosting temperature sensor(403) senses temperature of the evaporator. A micro computer(400) operates a defrosting operation by controlling the rotating motor after comparing temperature of the temperature sensor with the defrosting temperature sensor when the refrigeration room is not cool. Thereby, defrosting time of the evaporator and power are reduced. 본 발명은 냉장고 및 냉장고의 순환팬 제어방법에 관한 것으로, 히터에 의한 냉장실측 증발기의 제상시간을 줄이기 위한 시스템과 이에 따른 시스템 운전 방법을 제공한다. 본 발명은, 냉장실의 냉각이 이루어지지 아니하는 경우에도 냉장실의 온도와 냉장실측 증발기의 온도를 비교하여 이에 따른 냉장실측 순환팬의 가동을 제어하는 것을 주요한 특징으로 한다. 이러한 구성에 의하면, 냉장고의 소비전력이 절감되고 냉장실의 고습으로 인한 식품의 신선보존이 가능한 이점이 있다.
