REFRIGERATING SYSTEM AND AUTOMATIC VENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an automatic vending machine capable of reducing power consumption by utilizing waste heat of a refrigerating system for heating using a two-stage compression two-stage expansion cycle with respect to the automatic vending machine for vending commodities such as canned beverages while cooling or heating them. SOLUTION: This refrigerating system comprises a second low-stage discharge pipe 31 formed by branching a low-stage discharge pipe 30 connected from a low-stage discharge opening to a high-stage suction opening in parallel, and a discharge switching valve for switching flow channels of the low-stage discharge pipe 30 and the second low-stage discharge pipe 31, and the second low-stage discharge pipe 31 is utilized as a heat source while adjusting heat quantity by implementing a switching operation of the discharge switching valve, thus the heating is performed by utilizing the waste heat of the refrigerating system for heating using the two-stage compression two-stage expansion cycle to reduce power consumption.
