AUTOMATIC VENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an automatic vending machine capable of smoothly keeping each commodity storage chamber under an optimal temperature.SOLUTION: The automatic vending machine is provided with: an expansion valve 44 positioned on a downstream side of a cooling medium of a radiation indoor heat exchanger RHE and on an upstream side of the cooling medium of an endothermic indoor heat exchanger EHE; and a control device C that controls the expansion valve. The control device controls the expansion valve on the basis of a supercooling degree of the cooling medium at an outlet of the radiation indoor heat exchanger when the heat of the cooling medium is absorbed by an outdoor heat exchanger 62, and controls the expansion valve on the basis of the supercooling degree of the cooling medium at an outlet of the endothermic indoor heat changer when the heat of the cooling medium is absorbed by the endothermic indoor heat exchanger.SELECTED DRAWING: Figure 3
