摘要： A refrigerator may include a temperature sensor, a thermoelectric device module having a thermoelectric device, and at least one fan and configured to cool a storage compartment, and a controller that controls the output power of the thermoelectric device based on the temperature of the storage compartment, a set temperature, and the outside temperature. The output power of the thermoelectric device may be determined based on whether the temperature of the storage compartment is within a first temperature region including the set temperature, a second temperature region, or a third temperature region. In the first and second temperature regions, the thermoelectric device may operate at different output power and which gradually increases as the outside temperature increases. In the third temperature region, the thermoelectric device may operate at a third output power which exceeds the first output power and is greater than or equal to the second output power.
