VENDING MACHINE

PROBLEM TO BE SOLVED: To provide a vending machine stabilizing start of a compressor in a refrigeration circuit. SOLUTION: The vending machine 10 is provided with: storage interior evaporators 21-23 installed within storages 11-13, respectively; a storage exterior condenser 30 installed outside the respective storages 11-13; first on-off valves V1A-V1C installed between the evaporators 21-23 and the condenser 30; a compressor 40 for circulating a refrigerant between the condenser 30 and the evaporators 21-23; a valve train 80 for alleviating a pressure difference between the suction side and discharge side of a refrigerant of the compressor 40; and a control unit 100 for controlling opening/closing of the first on-off valves V1A-V1C and valve train 80 and operation of the compressor 40. Since the pressure difference between the suction side and the discharge side of the compressor 40 is alleviated by making a valve opening control of the valve train 80, the compressor 40 is started stably.
