Abstract: A refrigerator may include a temperature sensor, a thermoelectric device module having a thermoelectric device, and at least one fan and configured to cool a storage compartment, and a controller that controls the output power of the thermoelectric device based on the temperature of the storage compartment, a set temperature, and the outside temperature. The output power of the thermoelectric device may be determined based on whether the temperature of the storage compartment is within a first temperature region including the set temperature, a second temperature region, or a third temperature region. In the first and second temperature regions, the thermoelectric device may operate at different output power and which gradually increases as the outside temperature increases. In the third temperature region, the thermoelectric device may operate at a third output power which exceeds the first output power and is greater than or equal to the second output power.

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 may have an ultra-low temperature cooling module for cooling an ultra-low temperature compartment that includes a thermoelectric element having a heating surface and a heat absorption surface disposed to oppose the heating surface and a heat conduction unit evaporation part whose one side is in contact with the heating surface of the thermoelectric element and the other side is connected to a refrigerant pipe of an evaporator to transmit heat emitted from the heating surface of the thermoelectric element to the refrigerant. An amount of heat exchange between a central portion of the heating surface having a relatively high temperature and a refrigerant of the heat conduction unit evaporation part may be greater than an amount of heat exchange between a peripheral portion of the heating surface surrounding the central portion and the refrigerant.
