Refrigerator

A refrigerator comprising:

• a first sensor configured to measure a temperature of a storage compartment;
• a thermoelectric device module having a first fan and a second fan, and configured to cool the storage compartment;
• and
• a controller that controls rotation speed of the first and second fans,
• wherein the controller determines whether a 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 first fan or the second fan spins at a first rotation speed higher than 0 RPM,
• in the second temperature region, the first fan or the second fan spins at a second rotation speed greater than or equal to the first rotation speed, and
• in the third temperature region, the first fan or the second fan 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 an initial power condition exist such that power is initially supplied to the refrigerator, the first fan or the second fan 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, and
• wherein the thermoelectric device module includes:
• a thermoelectric device,
• a first heat sink disposed to contact with a heat absorption surface of the thermoelectric device and configured to undergo heat exchange with the storage compartment, and
• a second heat sink disposed to contact a heat radiation surface of the thermoelectric device and configured to undergo heat exchange outside the storage compartment,
• wherein
• the first fan is mounted to face the first heat sink and configured to blow air at the first heat sink, and
• the second fan is mounted to face the second heat sink and configured to blow air at the second heat sink,
• wherein in the first temperature region and in the second temperature region and in the third temperature region, a rotation speed of the second fan is higher than a rotation speed of the first fan.
