The present invention can produce following good effect compared with the prior art: the present invention overcomes traditional defective that the configuration of refrigerating medium heat-exchange system equipment is big, operating cost is high, compact conformation has the characteristics of energy-saving and environmental protection, good reliability, cost performance is reasonable, owing to adopted carbon dioxide (CO
2) do refrigerating medium, disposed rational system architecture form, therefore have following good effect:
1, the carbon dioxide (CO of Cai Yonging
2) refrigerating medium be the naturally occurring material of nature (ODP=0, GWP=1), good environmental protection.
2, carbon dioxide (CO
2) the refrigerating medium low price, have good economy, and do not have the recovery problem.
3, carbon dioxide (CO
2) evaporation latent heat of refrigerating medium is big, refrigerating effect per unit swept volume is big.
4, equipment and accessory configuration specification are little, whole system compact conformation, low, the energy saving in running of investment cost.

Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing preferred forms of the present invention is elaborated:
Embodiment: a kind of heat-exchange system (referring to accompanying drawing) that adopts carbon dioxide as coolant, a kind of heat-exchange system that adopts carbon dioxide as coolant, it is characterized in that it has cooling device 1, cooling device 1 passes through stop valve, pipeline connects the cooling medium inlet 6 of condenser 2, outlet 7, the refrigerating medium liquid outlet 10 of condenser 2 passes through stop valve, pipeline connects the refrigerating medium import 11 of storing expansion vessel 3, the refrigerating medium liquid outlet 15 of storing expansion vessel 3 passes through stop valve, pipeline connects pump 4, pump 4 passes through stop valve, pipeline connects evaporimeter 5, evaporimeter 5 passes through stop valve, pipeline connects the refrigerating medium return-air mouth 12 of storing expansion vessel 3, store the refrigerating medium gas outlet 13 of expansion vessel 3 and pass through stop valve, pipeline connects the refrigerating medium air inlet 9 of condenser 2, and the balance port 8 of condenser 2 is passed through stop valve, pipeline connects the balance port 14 of storing expansion vessel 3.During use, the cooling medium that produces in the cooling device 1 is entered by the cooling medium inlet 6 of condenser 2 by pipeline, stop valve, cooling medium absorbs heat in condenser 2 after, discharge by the cooling medium outlet 7 that connects condenser 2, and get back to cooling again in the cooling device 1 by pipeline, stop valve.While carbon dioxide (CO
2) refrigerating medium is condensed into liquid in condenser 2 after, refrigerating medium import 11 by the refrigerating medium liquid outlet 10 of condenser 2, the pipeline that links to each other with the refrigerating medium import 11 of storing expansion vessel 3, stop valve, storage expansion vessel 3 enters storage expansion vessel 3, stores the carbon dioxide (CO in the expansion vessel 3
2) secondary refrigerant liquid is by storing the refrigerating medium liquid outlet 15 of expansion vessel 3, the pipeline that links to each other with pump 4, stop valve enters pump 4, and pipeline by linking to each other with evaporimeter 5, stop valve is transported in the evaporimeter 5, after in evaporimeter 5, absorbing heat, pipeline by linking to each other again with the refrigerating medium return-air mouth 12 of storing expansion vessel 3, stop valve, the refrigerating medium return-air mouth 12 of storing expansion vessel 3 enters stores expansion vessel 3, after in storing expansion vessel 3, carrying out gas-liquid separation, again by storing the refrigerating medium gas outlet 13 of expansion vessel 3, the pipeline that links to each other with the refrigerating medium air inlet 9 of condenser 2, stop valve, the refrigerating medium air inlet 9 of condenser 2 is got back to and is condensed into liquid in the condenser 2 in this system.The balance port 8 of condenser 2 is passed through stop valve, pipeline connects the balance port 14 of storing expansion vessel 3, and when moving, condenser 2 and 3 pressure balances of storage expansion vessel are guaranteed the carbon dioxide (CO that condensation is got off in the condenser 2 with the assurance system
2) secondary refrigerant liquid can successfully flow into and store in the expansion vessel 3, be provided with and store expansion vessel 3, with the assurance system when out of service, avoid the sharp increase of refrigerating medium system pressure, its operation principle is: after system is out of service, because ambient temperature effect, the pressure of refrigerating medium side can sharply increase, the pressure that increases by by with store pipeline, stop valve that expansion vessel 3 joins and release to and store in the expansion vessel 3, finally make the pressure of whole refrigerating medium side reach balance under the pressure of design, thereby guarantee that whole system is safe and reliable; When system moves, because the condensation of condenser 2, the pressure of refrigerating medium side constantly descends in the condenser 2, and the refrigerating medium gas in the system in other equipment just constantly enters in the condenser 2 by equalizing main, the stop valve that links to each other with condenser 2 and is condensed into liquid, finally reaches balance.
