Patent ID: 6865899

Claim:
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.
