PROBLEM TO BE SOLVED: To reduce the power consumption of a compressor by decreasing the time of a "one-Eva" operation (an operation for stopping cooling one storeroom and continuing to cool the other storeroom) which reduces a COP (Coefficient of Performance) after a "two-Eva" operation (an operation for cooling two storerooms by passing a coolant through two evaporators, respectively) is changed to the "one-Eva" operation in a vending machine or to reduce the power consumption of a heater by reducing the time of one-heater operation after a two-heater operation is changed to the one-heater operation. SOLUTION: A partition wall 18ab partitioning the storerooms 13a and 13b is removed, and consequently the air in the storeroom 13a, which is adjacent to the storeroom 13b and cooled prior to the storeroom 13b, is free to flow toward the storeroom 13b which is hard to cool. Further, an air-passing window 29 is provided in the partition wall 28, or an extension and shrinkage part 59 which can extend and shrink in the front and rear directions is provided in the partition wall 58, and the extension and shrinkage part 59 is arranged so that it may contact an inner door 12 with its shrunk state, and a gap 51 through which the air in the storeroom freely flows is formed along the rear end part of the partition wall 58.
