ABSTRACT:
A refrigerator having a device for opening/closing cool air supply ports is disclosed. The refrigerator has a sensor for sensing temperature in a cooling compartment, a motor for driving the device, and a control part for controlling the motor so that an open degree of the cool air supply ports are controlled by the device on the basis of the temperature difference between the sensed temperature and a standard temperature. Since the open degree of the cool air supply ports is controlled according to the standard temperature and the real temperature of the cooling compartment, the temperature of the cooling compartment is exactly controlled.
