PROBLEM TO BE SOLVED: To provide a vending machine capable of realizing energy-saving, disuse of chlorofluorocarbons, and noise reduction at the same time. SOLUTION: Cold generated in a freezing cycle is used for cooling a commodity, while heat is used for heating the commodity, and surplus heat or cold saved by temperature control is radiated by a wall face heat exchanger 22 and a bottom face heat exchanger 24 using a main body case 1. As a refrigerant, an HC refrigerant is used, and a heat pump with a great temperature difference is realized. The bottom face heat exchanger 24 and a bottom face air duct structure are arranged, so that leakage of operation noise can be reduced. COPYRIGHT: (C)2003,JPO
