摘要： A refrigerator may include a sensor configured to measure temperature, a thermoelectric device module having at least one fan and configured to cool the storage compartment; and a controller that controls a rotation speed of the fan. The rotation speed of the fan may be determined based on at least one of whether a storage compartment temperature condition measured by the sensor exists or whether an initial power input condition exists. The thermoelectric device module may be controlled differently in a first temperature region, in a second temperature region, and in a third temperature region of the storage compartment. When an initial power condition exist such that power is initially supplied to the refrigerator, the fan is controlled to spin at a rotation speed that exceeds a rotation speed corresponding to the third temperature region until a preset temperature within the second temperature region is reached.
