Foreign economic cooperation Office of the Ministry of environmental protection said by 2015 are key to alternative refrigerant a year. By the end of 2015, 10% hydrogen will eliminate chlorofluorocarbons (HCFCs) refrigerant, and R32 refrigerant of low carbon and CO2 refrigerant is entering the market.
In accordance with the relevant classification of refrigerants, R11, R12, R13, R14, R113, R114 are CFCs refrigerant, is totally eliminated; Belonging to HCFCs such as R22, R123, R142b refrigerant; R134a and R410a, R407c, etc belong to HFCs refrigerants. Current hydrogen-containing chlorofluorocarbons (HCFC) is the chlorofluorocarbons (CFC) transitional substitutes, although the damage to the ozone layer than the former, but long-term and extensive use, the destruction of the ozone layer is still to be reckoned with. Very high greenhouse effect potential of HCFC, phase-out of HCFC is imperative.
