A refrigerator comprising: a sensor (192, 192, 193) configured to measure the temperature of a storage compartment; a thermoelectric device module having at least one fan (173, 176) configured to cool the storage compartment; and a controller configured to control a rotation speed of the at least one fan (173, 176), wherein the rotation speed of the at least one fan (173, 176) is determined based on a storage compartment temperature condition measured by the sensor (192, 192, 193) and whether an initial power input condition exists, wherein the initial power condition includes that power is initially supplied to the refrigerator, wherein the controller is configured to determine whether the storage compartment temperature condition exists based on whether the temperature of the storage compartment falls within a first temperature region that includes a set temperature input by the user, a second temperature region which is higher than the first temperature region, and a third temperature region which is higher than the second temperature region, wherein in the first temperature region, the at least one fan (173, 176) spins at a first rotation speed higher than 0 RPM, in the second temperature region, the at least one fan (173, 176) spins at a second rotation speed greater than or equal to the first rotation speed, and in the third temperature region, the at least one fan (173, 176) spins at a third rotation speed which exceeds the first rotation speed and is greater than or equal to the second rotation speed, and wherein, when the initial power condition exists, the at least one fan (173, 176) is controlled to spin at a rotation speed that exceeds the third rotation speed corresponding to the third temperature region until a preset temperature within the second temperature region is reached, even after the temperature of the storage compartment drops into the second temperature region from the third temperature region. a sensor (192, 192, 193) configured to measure the temperature of a storage compartment; a thermoelectric device module having at least one fan (173, 176) configured to cool the storage compartment; and a controller configured to control a rotation speed of the at least one fan (173, 176), wherein the rotation speed of the at least one fan (173, 176) is determined based on a storage compartment temperature condition measured by the sensor (192, 192, 193) and whether an initial power input condition exists, wherein the initial power condition includes that power is initially supplied to the refrigerator, wherein the controller is configured to determine whether the storage compartment temperature condition exists based on whether the temperature of the storage compartment falls within a first temperature region that includes a set temperature input by the user, a second temperature region which is higher than the first temperature region, and a third temperature region which is higher than the second temperature region, wherein in the first temperature region, the at least one fan (173, 176) spins at a first rotation speed higher than 0 RPM, in the second temperature region, the at least one fan (173, 176) spins at a second rotation speed greater than or equal to the first rotation speed, and in the third temperature region, the at least one fan (173, 176) spins at a third rotation speed which exceeds the first rotation speed and is greater than or equal to the second rotation speed, and wherein, when the initial power condition exists, the at least one fan (173, 176) is controlled to spin at a rotation speed that exceeds the third rotation speed corresponding to the third temperature region until a preset temperature within the second temperature region is reached, even after the temperature of the storage compartment drops into the second temperature region from the third temperature region.
