Abstract: A refrigerator includes: a control unit for controlling a thermoelectric module, a cooling fan, and a heat-radiation fan, in which when the outside temperature exceeds the set temperature, the control unit rotates 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 and the storage chamber temperature is in the upper limit range, the control unit rotates 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 rotates each of the cooling fan and the heat-radiation fan at a low-speed lower than a medium-speed.
