ABSTRACT:
A temperature setting part sets a reference temperature of the interior of a refrigerating compartment of a refrigerator. A door opening/closing detection part detects opening and closing of a door of the refrigerating compartment. First and second temperature detecting parts detect the interior and exterior temperatures of the refrigerating compartment respectively. An air curtain fan driving part drives an air curtain fan. A control part performs a normal cooling operation to control the interior temperature of the refrigerating compartment by driving the cooling fan when the interior temperature is under a reference temperature, drives the air curtain fan with each of the numbers of rotations corresponding to each of several temperature ranges, and performs the normal cooling operation by stopping the driving of the air curtain fan if the closing of the door of the refrigerating compartment is detected. Cooling efficiency and electric power efficiency are enhanced by efficiently driving the air curtain fan according to the interior and exterior conditions of the refrigerating compartment.
