Disclosed herein is a refrigerator that is capable of rapidly handling a load in a freezing chamber of the refrigerator or a refrigerating chamber of the refrigerator, and preventing stored goods in a rapid cooling chamber from being excessively cooled. The present invention also provides a method of controlling such a refrigerator. The refrigerator comprises a rapid cooling chamber mounted in at least one of the freezing and refrigerating chambers, a rapid cooling channel having one end communicating with an entering channel of the refrigerating chamber and the other end communicating with the rapid cooling channel, and a damper for controlling the flow of cool air passing through the entering channel of the refrigerating chamber and the rapid cooling channel. The damper is controlled on the basis of the load in the freezing or refrigerating chamber and a load in the rapid cooling chamber.

1. A refrigerator comprising:a compressor for compressing coolant; a condenser for condensing the coolant compressed by the compressor so that heat from the coolant passing through the condenser is emitted to air surrounding the condenser; an expander for decompressing the coolant condensed by the condenser; an evaporator for evaporating the coolant expanded by the expander so that the expanded coolant passing through the evaporator absorbs heat from air surrounding the evaporator; a blowing fan for blowing the air cooled by the evaporator to a freezing chamber of the refrigerator or a refrigerating chamber of the refrigerator and blowing the cool air in the freezing, chamber or the refrigerating chamber to the vicinity of the evaporator so that the cool air is circulated in the refrigerator; a rapid cooling chamber mounted in at least one of the freezing and refrigerating chambers; a rapid cooling channel having one end communicating with an entering channel of the refrigerating chamber and the other end communicating with the rapid cooling channel; a damper for controlling the flow of cool air passing through the entering channel of the refrigerating chamber and the rapid cooling channel; a load sensing sensor for sensing a load-in the freezing chamber or the refrigerating chamber; a load-based cooling module for sensing a load in the rapid cooling chamber and supplying the cool air guided along the rapid cooling channel to the sensed load; and a controller for controlling the compressor, the blowing fan, the damper, and the load-based cooling module on the basis of signals outputted from the load sensing sensor and the load-based cooling module. 2. The refrigerator as set forth in claim 1, wherein the rapid cooling chamber comprises:a rapid cooling panel attached to the freezing chamber or the refrigerating chamber, the rapid cooling panel having a stored goods receiving space defined therein and a stored goods entrance formed at the front part thereof; and a lid pivotably attached to the rapid cooling panel for closing the stored good entrance of the rapid cooling panel. 3. The refrigerator as set forth in claim 2, further comprising guides for facilitating the attachment of the rapid cooling panel to the freezing chamber or the refrigerating chamber.4. The refrigerator as set forth in claim 1, further comprising a barrier disposed between the freezing chamber and the refrigerating chamber so that the freezing chamber and the refrigerating chamber are separated from each other, the barrier having the entering channel of the refrigerating chamber formed therein,wherein the rapid cooling channel is formed in the barrier. 5. The refrigerator as set forth in claim 1, wherein the load-based cooling module is attached to the barrier while facing the interior of the rapid cooling chamber.6. The refrigerator as set forth in claim 1, wherein the load-based cooling module comprises:a module case attached to the barrier; a motor mounted in the module case; a nozzle connected to the motor, the nozzle having an inlet communicating with the rapid cooling channel and an outlet communicating with the rapid cooling chamber; and an infrared sensor mounted at a side of the nozzle for scanning the interior of the rapid cooling chamber to sense the location and the temperature of the load.
