![]() Comparative 100 year GWP: HFC410A, 2,090 HFC32, 675.Ĭooperation with governments and international organizations has expanded technical assistance for emerging countries to each region and aims for widespread use of the refrigerant R-32 throughout the world. 2) Lowered the leak rate thresholds that trigger the duty to repair refrigeration and air-conditioning equipment containing 50 or more pounds of refrigerant. Various types of refrigerants are available such as Chlorofluorocarbon (CFC). *1) Values for 100 year global warming potential (GWP) from IPCC Fourth Assessment Report. Refrigerant is a fluid used in air conditioners and refrigerators.Daikin became the world’s first company to succeed in applying R-32 to air conditioners by leveraging its expertise as the only manufacturer that develops and manufactures both air conditioners and refrigerants. Freon 407C and 407A Refrigerants (R-407C and R-407A) Properties, Uses, Storage, and Handling Introduction Background Chlorodifluoromethane (R-22 or HCFC-22) has been used as a refrigerant in various refrigeration, industrial cooling, air conditioning, and heating applications for over five decades. However, because R-32 had been an extremely difficult refrigerant to handle, its use was not practical until now. It’s one of several new technologies emerging under the pressure of consumer action and international efforts to phase out the use of ozone-damaging chlorofluorocarbons. In the 1980s, the R-12 composition of chlorofluorocarbons (CFCs) was linked. Chris Spurgeon of member station WHYY in Philadelphia reports on the development of a new, CFC-free air conditioning system. Consequently, investigation of R-32 has increased as a promising refrigerant with smaller environmental impact. You might be wondering which kind of freon your cars air conditioner uses. ![]() While R-32 also has an ozone depletion potential of 0, the refrigerant has only approximately 1/3 of the GWP of R-410A. Regulations have increasingly become stricter from greater consideration for the global environment because of the Montreal Protocol in 1987 and the Kyoto Protocol in 1997, resulting in a shift to refrigerants with even lower environmental impact.Īlthough the mainstream refrigerant R-410A has an ozone depletion potential (ODP) of 0, its global warming potential (GWP) still remains an issue. Various refrigerants have been used in air conditioners until now. ![]()
