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.
