  • Freezer and refrigerator provided with freezer
    Patent number: 6775998
    Abstract: Respective evaporators are set to a proper value in evaporation temperature and the efficiency in refrigeration cycle is enhanced, resulting in a reduction of energy consumption. A refrigerating unit and a refrigerator comprise a compressor, a condenser, a plurality of evaporators connected in series, a refrigerant flow rate adjustable unit and a refrigerant, thereby constituting a refrigeration cycle. The refrigerant flow rate adjustable unit controls each respective evaporation temperature of the plurality of evaporators. Preferably, the refrigeration unit further comprises a bypass circuit bypassing at least one of the plurality of evaporators and, when needs arise, the refrigerant is channeled through the bypass circuit.
    Type: Grant
