    • PROBLEM TO BE SOLVED: To provide a vending machine wherein abnormally high temperature of a compressor is limited by circulating refrigerating machine oil through a refrigerant circuit without causing stagnation thereof in a heat exchanger, and the compressor can be operated with high reliability.
      SOLUTION: A refrigerant circulation circuit is constituted of a compressor, a condenser solenoid valve, a condenser, an expander, a distributor, a solenoid valve at the inlet of compartment, a plurality of heat exchangers in compartment, a solenoid valve at the outlet of compartment, and a collector, and heating inlet piping which connects between the solenoid valve at the inlet of compartment and the heat exchanger in compartment through a heating inlet solenoid valve connected in parallel with the condenser solenoid valve from the compressor, and heating outlet piping which connects with the distributor through a heating outlet solenoid valve and the expander from between the heat exchanger in compartment and the solenoid valve at the outlet of compartment are provided in the refrigerant circulation circuit, so that refrigerant flows in the same direction through the heat exchanger in compartment during both cooling operation and heating operation, and stagnation of refrigerating machine oil in the heat exchanger in compartment is limited.
