    Abstract: A refrigerator includes a first freezing cycle in which a first refrigerant circulates and having a first compressor, a first condenser, at least one first expansion mechanism, and at least one first evaporator, the first freezing cycle configured to cool freezing and refrigerating compartments, a freezing compartment sensor, a refrigerating compartment sensor, a second freezing cycle in which a second mixed refrigerant having a lower evaporation temperature than the first refrigerant circulates and having a second compressor, a second condenser, a second expansion mechanism, and a second evaporator, the second freezing cycle configured to cool a deep freezing compartment, a deep freezing compartment sensor, and a controller configured to operate the first freezing cycle and the second freezing cycle independently or simultaneously, thereby more efficiently cooling the freezing and refrigerating compartments and the deep freezing compartment.

    Abstract: A refrigerator includes: a main body having a storage chamber; a door for opening and closing the storage chamber; a thermoelectric module for cooling the storage chamber; an outside temperature sensor for detecting an outside temperature; a storage chamber temperature sensor for detecting the storage chamber temperature; and a control unit for applying a voltage within a range between the maximum voltage and the minimum voltage to the thermoelectric module. The control unit applies the set voltage, not the maximum voltage, to the thermoelectric module when the outside temperature is the uppermost outside temperature range among the plurality of outside temperature ranges and thus the temperature of the control is lowered and power consumption is reduced.

    Abstract: A refrigerator is provided that may include at least one compressor that compresses a refrigerant, a condenser that condenses the refrigerant compressed in the at least one compressor, a refrigerant tube that guides the refrigerant condensed in the condenser, a plurality of evaporation passages, in which expansion devices may be respectively disposed, the plurality of evaporation passages branching from the refrigerant tube, a flow adjuster disposed in the refrigerant tube to supply the refrigerant into at least one evaporation passage of the plurality of evaporation passages, a plurality of evaporators, respectively, connected to the plurality of evaporation passages to evaporate the refrigerant decompressed in the plurality of expansion devices, and a liquid refrigerant supply device disposed at an outlet-side of the condenser to separate a liquid refrigerant of the refrigerant heat-exchanged in the condenser, thereby supplying the liquid refrigerant into the flow adjuster.
