To provide a heating/cooling device preventing a refrigerant amount from being excessively increased by suppressing a heat radiation amount of a gas cooler in heat pump operation, and to provide an automatic vending machine equipped with the heating/cooling device.
This heating/cooling device 100 is an element constituting a refrigeration cycle, and has a gas cooler 4 and a heat radiator 3 cooling a high-pressure high-temperature refrigerant. An opening/closing valve 34 is installed upstream of the gas cooler 4, a check valve 47n is installed downstream thereof, and a bypass pipe 44 installed with a bypass opening/closing valve 44v bypassing them is provided. A controller shares the high-temperature high-pressure refrigerant in the heat radiator 3. When supplying a low-temperature low-pressure refrigerant to evaporators 6a, 6b, the controller starts a compressor 1, thereafter opens the bypass opening/closing valve 44v when a prescribed time lapses to open the pipe bypass 44, and closes the opening/closing valve 34v to shut the refrigerant in the gas cooler 4.
