Refrigerator driving control apparatus and method thereof

摘要

A refrigerator has an evaporator to discharge cold air into a food storage chamber by rotation of a fan as the cold air is generated during circulation of a coolant, and a temperature detecting unit to detect the temperature of the evaporator and generate a signal related to the evaporator temperature. The fan is controlled to initially rotate at a low speed (when the evaporator is warmest) and then at a progressively increasing speed. The increasing speed is independent of the temperature of the food storage chamber. The speed could be increased in response to detected decreases in the evaporator temperature. Alternatively, the speed could increase automatically for a predetermined time period.
