PROBLEM TO BE SOLVED: To prevent a capacity of a condenser from becoming excessive or deficient. SOLUTION: A cooling system comprises evaporators 4, 5 and 6 which are arranged in article storage spaces 1, 2 and 3; a compressor 7, the condenser 8 and expansion valves 9 which are set outside a section of the article storage spaces is provided. A plurality of outside fans 10 for promoting a heat exchange in the condenser are arranged near the condenser 8. An air temperature sensor to detect a surrounding temperature of a vending machine is set. The number of the outside fans 10 to be operated is changed based on a signal value of the air temperature sensor. All the outside fans 10 are operated at a high air temperature, and the number of the outside fans 10 to be operated is reduced at a low air temperature. COPYRIGHT: (C)2007,JPO&INPIT
