  • Patent number: 6923015
    Abstract: A refrigerator includes a refrigerating cycle unit for refrigerating an atmosphere in the refrigerator by means of heat absorption due to change of a flammable refrigerant from a liquid phase to a gaseous phase, and a deodorizer having first and second electrodes discharging electricity upon application of high voltage to them, producing ozone, a burning chamber provided so as to surround the first and second electrodes, and a fire-spread preventing unit provided in the burning chamber to prevent burning of the flammable refrigerant in the burning chamber from spreading outside the burning chamber.

  • Publication number: 20050086952
    Abstract: A refrigerator-freezer is described, in which refrigerant leakage from the refrigeration cycle can be safely detected. The refrigerator-freezer comprises: a refrigeration cycle formed by a compressor, a capillary, an evaporator and an accumulator connected in series, and filled with a flammable refrigerant; a cooling fan configured to blow the cold air cooled by the evaporator in the refrigerator-freezer; and a refrigerant leakage detection system configured to detect leakage of the flammable refrigerant, wherein the refrigerant leakage detection system is provided with a temperature sensor configured to measure the temperature of a refrigerant conduit of the evaporator and judges that the flammable refrigerant is leaking in the low pressure side of the refrigeration cycle when the temperature is detected by the temperature sensor with the compressor being halted is no lower than a predetermined temperature.
