MVAC systems are one end-use within the refrigeration and air conditioning sector. Klea is a brand of Koura and is a registered trademark of Mexichem SAB de C.V. Koura is part of Orbia, a community of companies working together to tackle some of the worlds most complex challenges. This includes all hydrocarbon refrigerants. The good news is that the answers to these questions are pretty straightforward. It just wouldnt work with R410A. In Japan, the Act on Rational Use & Proper Management of Fluorocarbons specifies the date the refrigerant will be banned for each application according to its GWP. endstream endobj 325 0 obj <>stream It is an offence under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 (the Act) to manufacture or import equipment that is charged with a chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC) refrigerant, or designed to operate solely using a CFC or HCFC refrigerant. These were seen as a temporary solution as CFCs were phased out due to the chlorines impact on the environment, but remained on the market much longer than anticipated. EPAs regulatory requirements for the servicing of MVAC systems apply to all three of these refrigerants. In 2012, automobile manufacturers began the transition to new, climate-friendly alternative refrigerants. Ozone loss in the atmosphere allows higher levels ofUVBto reach the Earth's surface and leads to negativehealth and environmental effects. Specifically, Opteon XL refrigerants have an ASHRAE and ISO Safety classification of A2L and deliver very low GWP solutions (for instance, Opteon XL10 has a GWP of <1). If you wish to convert your R22 system to an R410A, this will need to be carried out by a specialist. It hasnt been actively produced for several years now. On January 1, 2022, the U.S. officially started its phase down of HFC refrigerants, such as R-410A and R-404A.
