Abstract:

To provide a heating/cooling system capable of reducing electric power consumption.

This heating/cooling system 100 having storage chambers 2, 3, 4 switchabl to hot/cold is composed of a compressor 11, a gas cooler 12, a radiator 13, a radiator 14, a radiator 15, an expansion valve 16, an evaporator 17, a radiator 18, a radiator 19, an auxiliary evaporator 55 or the like. This system is provided with a refrigerant circuit 10 in which carbon dioxide is sealed as refrigerant and whose pressure on a high pressure side becomes supercritical pressure. The inside of the storage chambers 2, 3, 4 is heated by the radiators 13, 14, 15, respectively, and is cooled by the evaporators 17, 18, 19, respectively. This system is provided with a flow passage control means for controlling refrigerant circulation for each of the radiators 13, 14, 15, the evaporators 17, 18, 19, the gas cooler 12, and the auxiliary evaporator 55.
