PURPOSE:To provide a refrigerator wherein a refrigeration preservation having less degradation in quality is executed with an suppression of oxidation of lipid and coloring matter, a preservation at low oxygen quantity condition and a good refrigeration condition. CONSTITUTION:There is a control composition wherein at a corner of a refrigeration chamber, a closed chamber 17 is formed, in the closed chamber 17, a direct cooler 18 is arranged, and an oxygen selecting permeation membrane 20 of air in the closed chamber 17 and a suction means 21 are provided with and the suction means 21 executes a forced continuous operation during a predetermined time by detecting a downward pressing of an oxygen decreasing switch 23 which denotes a beginning sign of an oxygen decreasing treatment of the closed chamber 17. And by detecting downward pressing of a rapid refrigeration switch 24 which denotes a beginning sign of a rapid refrigeration treatment of the closed chamber 17, during a predetermined time, a compressor 10 and a blower 12 execute forced continuous operation, and a solenoid valve opening degree which is set in a refrigeration cycle is made to become up and a refrigerant flowing-in quantity to a directly cooling cooler 18 is made to increase. |
