PROBLEM TO BE SOLVED: To provide a cooling means such as a refrigerator for keeping cooling capacity in a storage without deteriorating heat exchange efficiency of coolers. SOLUTION: For preventing the deterioration in the cooling capacity of the respective coolers 10 and 11, a passing wind speed for passing through the inside of the coolers 10 and 11 is varied according to a lowering speed of a storage inside temperature by frosting to the respective coolers 10 and 11 until defrosting time of the coolers 10 and 11 comes. For varying the passing wind speed in the respective coolers 10 and 11, a rotating speed of respective air blowers 20 and 21 is controlled, or a valve 29 (such as a damper) is arranged in a duct for constituting the cold air circulation of a cooler room 40, a refrigerating room 7, and a vegetable room 8, or a valve 36 (such as a damper) is arranged in a duct for constituting the cold air circulation of a cooler room 41 and a freezing room 9, and an opening-closing angle of the valves 29 and 36 is controlled.
