The new agreement about “accelerate the phase-out of production and consumption of hydro-chlorofluorocarbons (HCFCs)” on the 19th meeting of the Parties to the Montreal Protocol put much more pressure on Chinese refrigeration industry. On the basis of message gotten from the conferences organized by UNIDO in Vienna in 2008 and UNEP in Cairo in 2010

the author summarized the research progress in the HCFCs replacement in recent years in the world. EU have been developing natural refrigerants

such corporations as Dupont are researching and propagating the good performances of HFO-1234yf

DR-2

etc.

while the countries in Africa and south-east Asia put more attention to where to get the refrigerant replacement technology and the fund. As for China

besides R32 being considered as a interim refrigerant suitable for China's actual conditions

more works should be done on the development of such natural refrigerants as CO2

R290 as well as the alternative refrigerants with low GWP and thermodynamic properties similar to HCFCs. In addition

special attention should be paid to the standards for the replacement of HCFCs

which is the motivation for the development of refrigeration industry.
