PROBLEM TO BE SOLVED: To provide a refrigerator capable of keeping clean by preventing dew generation on the opening of a storage chamber.SOLUTION: A refrigerator includes a temperature sensor 14 for detecting the temperature at the opening of a storage chamber, a humidity sensor 15 for detecting the humidity of outside air, a compressor 31 operated at a refrigeration cycle, a heat radiator 33 disposed in the high-temperature part of the refrigeration cycle, an expander 34 disposed after the heat radiator 33, a dew generation prevention part 12 disposed between the heat radiator 33 and the expander 34 and at the opening of the storage chamber, and a bypass passage 13 disposed in parallel with the dew generation prevention part 12. A refrigerant is switched between the dew generation prevention part 12 and the bypass passage 13 to flow on the basis of the detection results of the temperature sensor 14 and the humidity sensor 15. When the humidity sensor 14 is not operated normally, an always dew generation prevention operation is performed to supply the refrigerant only to the dew generation prevention part 12. |
