A refrigerator provided by the embodiment of the invention includes: a main body having a storage chamber; a door for opening and closing the storage chamber; a thermoelectric module having a coolingsink for cooling the storage chamber and a
heat sink for radiating heat sucked by the cooling sink; a cooling fan for circulating air to the cooling sink and the storage chamber; a heat-
radiation fanfor flowing outside air to the
heat sink; and a
control unit for controlling the thermoelectric module, the cooling fan, and the heat-
radiation fan, in which when the outside temperature exceeds the set temperature, the
control unit can rotate each of the cooling fan and the heat-
radiation fan at a high-speed, in which, when the outside temperature is equal to or lower than the set temperature andthe storage chamber temperature is in the upper limit range, the
control unit can rotate each of the cooling fan and the heat-radiation fan at a medium-speed lower than a high-speed, and in which, when the outside temperature is equal to or lower than the set temperature and the storage chamber temperature is lower than the upper limit range, the control unit can rotate each of the cooling fan and the heat-radiation fan at a low-speed lower than a medium-speed, and thus there are advantages that the temperature deviation in the storage chamber, which can be generated when the outside temperature is high, can be minimized and
noise can be minimized when the outside temperature is not high.
