PROBLEM TO BE SOLVED: To reduce power consumption by reducing the intrusion of heat from a heat-insulating box body flange part, and the same time to prevent dew condensation from being formed at the heat-insulating box body flange part in a refrigerator. SOLUTION: In a refrigerator, a plurality of storerooms are formed inside, a compressor 5, a condenser 6, pressure-reducing equipment 8, and an evaporator 9 are mounted to a heat-insulating box body with a heat-insulating door and are annually connected by piping for composing a refrigeration cycle, and the storeroom is cooled by chilled air being generated by the freezing cycle. Also, in the refrigerator, condensation prevention piping 7 being buried in heat- insulating box body and partition flange part is formed by the piping between the condenser 6 and the pressure-reducing equipment 8, a high-temperature refrigerant from the condenser 6 is introduced, and at the same time a three-way solenoid valve 13 for allowing the condensation prevention piping to detour and for introducing the high-temperature refrigerant is provided in piping to the condensation prevention piping 7.
