Abstract

Disclosed are a method for controlling a temperature of a refrigerator, and a refrigerator having the same. The refrigerator comprises a refrigerator body having a refrigeration chamber and a freezing chamber, a cool air duct having suction ports and discharge ports communicated with the refrigeration chamber and the freezing chamber, respectively, a damper configured to open or close the discharge port of the refrigeration chamber, an evaporator installed in the cool air duct, and configured to heat-exchange a refrigerant and cool air with each other, a blowing fan configured to discharge the cool air to the discharge port via the evaporator, a compressor configured to compress the refrigerant, a condenser connected to the compressor, a three-way valve connected to the condenser, first and second expansion units connected to two outlets of the three-way valve, the second expansion unit having an opening degree larger than that of the first expansion unit, and a controller configured to control an open or closed state of the three-way valve according to temperatures of the freezing chamber and the refrigeration chamber.
