ABSTRACT:
A refrigerator has a device for generating an air curtain, and the air curtain generating device operates according to the sensor for sensing the opening/closing of the door and the temperatures in the cooling compartment sensed by temperature sensors. The air curtain is generated when the door is opened and when the temperature of the area near the door is higher than the temperature of the area distant from the door. Thus, the area near the door in the cooling compartment is efficiently cooled when the door is closed, and the operation for generating an air curtain is exactly performed when the door is opened even if the sensor for sensing the opening/closing of the door is out of order.
