PROBLEM TO BE SOLVED: To satisfactorily cool internal air of a plurality of commodity storage chambers which are cooled to different temperature ranges from each other.SOLUTION: A vending machine comprises: cooling units which are provided to each of commodity storage chambers 3 in order to cool internal air thereof; and a cooling operation control part 50 which drives first cooling units for cooling internal air of normal cooling chambers and drives second cooling units for cooling internal air of low temperature cooling chambers. The cooling operation control part 50 drives the first cooling units and the second cooling units until all in-chamber temperatures are at or below a priority cooling starting temperature T0 and performs priority cooling in which it drives only the second cooling units while the temperatures are at or below the temperature T0. Subsequently, when the in-chamber temperatures of all cooling chambers are at or below a low temperature cooling off temperature, it allows the first cooling units to drive.SELECTED DRAWING: Figure 4 |
