PROBLEM TO BE SOLVED: To provide a heat exchange system having high heat exchanging efficiency, and capable of reducing labor and costs for construction, and saving energy.SOLUTION: A heat exchange system includes a piping system (La) and water storage equipment (150, GH) for soaking the piping system in water, and the piping system (La) is constituted to allow a heat medium to pass therein and has a function for exchanging heat with the water in the water storage equipment. The heat medium is carbon dioxide, heat is exchanged between vaporization heat of carbon dioxide and the water in the water storage equipment, and a temperature of carbon dioxide flowing in a region out from the water storage equipment in the piping system is determined to be 5°C-40°C to exchange between the vaporization heat of carbon dioxide and the water in the water storage equipment. |
