PROBLEM TO BE SOLVED: To provide a vending machine that prevents temperature rise of a compressor operating under a high ambient temperature. SOLUTION: A refrigerant circuit 1000c of the vending machine 1000 includes: a compartment cooling piping system 100C that sequentially connects a compressor 1, a gas cooler 2, a compartment cooling expansion means 4, a left compartment evaporator 6L or the like, and the compressor 1 to circulate a refrigerant; and a compartment heating piping system 100H that sequentially connects the compressor 1, a left compartment condenser 7L or the like, the gas cooler 2, and a joint 8 to the compartment cooling piping system 100C to supply the refrigerant into the compartment cooling piping system 100C. Bypass piping 81 is disposed so as to branch between the joint 8 and the compartment cooling expansion means 4 and merge between the left compartment evaporator 6L or the like, and the compressor 1. The bypass piping 81 is provided with a bypass expansion means (capillary) 81e and a bypass solenoid valve 81v. COPYRIGHT: (C)2010,JPO&INPIT
