PROBLEM TO BE SOLVED: To lower an operation factor by efficiently carrying refrigerants into a plurality of evaporators to prevent useless cooling operation, related to a vending machine. SOLUTION: Orders of priority are given to a plurality of the evaporators 25, 26 and 27 so that two chambers having high orders of priority are cooled in priority when a plurality of storage chambers 32, 34 and 36 are in cooled states. This prevents a sharp change of an evaporating temperature and allows a change in the rotating speed of the compressor 24 to follow the change of the evaporating temperature, thereby keeping the evaporating temperature almost constant. As a result, the highly efficient vending machine is obtained. COPYRIGHT: (C)2007,JPO&INPIT
