The R410A phase-out is underway. R32 and R454B are popular refrigerants manufacturers have been turning to as replacements. ASHRAE has classified these refrigerants as A2L, which means they are mildly flammable. However, there is a lot of misinformation surrounding the safety of these refrigerants. Many people mistakenly believe they are unsafe to use because they are “flammable.” This is not true. A2L refrigerants have been used safely worldwide for many years. A2L refrigerants have been extensively tested and are safe when used in the proper applications. Manufacturers, as key players in this process, have been working diligently to ensure that their equipment is designed and tested to meet the safety standards required for using these refrigerants, thereby playing a crucial role in their safe use. In conclusion, while A2L refrigerants such as R32 and R454B are mildly flammable, they are still very safe when used correctly. Their safety has been extensively tested, and they are suitable for various applications. As we continue to phase out R410A, we will likely see more widespread use of these refrigerants. Thanks, The Chemours Company, for leading the way in educating the HVAC community on A2L refrigerants.

All refrigerants are flammable, but not all refrigerants are flammable in the same way. There are many variables that must be weighed when considering refrigerant flammability. On our refrigerant transition page, we explain what the move to A2L (a lower-flammability refrigerant) means for the HVAC industry, and what to expect with safety protocol updates. https://ow.ly/6wwg30sCpAu

?????? 6 Month Refrigerant Phase-Out Alert!!! ?????? July 1st marked the 6-month count down until the first major refrigerant phase out deadline for new equipment. Most HVAC equipment using R-410a or other refrigerants with a GWP above 700 can no longer be manufactured, or imported, into the United States beyond 1/1/2025. As a result, many custom-built equipment already passed their ‘last order date’ and must use new refrigerants. Many other types of equipment are approaching their last order dates, dependent on quantities and on where they are being manufactured. We are releasing more and more design information for new products with low GWP refrigerants every month, and we can already deliver some equipment with new refrigerants. Meanwhile, many members of our organizations continue to participate in codes and standards groups and meetings surrounding new low GWP A2L refrigerants. In Massachusetts, we have been working with BBRS on code change proposals to amend our 10th edition building code for proper allowance of A2Ls in all system types.

A2L refrigerants are indeed the next generation of low Global Warming Potential (GWP) refrigerants developed to combat climate change. 1. Ventilation Requirements: Systems using A2L refrigerants often need enhanced ventilation to ensure that any leaked refrigerant does not accumulate to flammable concentrations. 2. Detection Systems: Installing refrigerant leak detection systems is crucial to identify leaks quickly and prevent hazardous situations. 3. Refrigerant Charge Limits: There are specific limits on the amount of A2L refrigerant that can be charged in a system, especially in occupied spaces, to minimize risk. 4. Equipment Design: HVAC equipment must be specifically designed and certified for use with A2L refrigerants, including components like compressors, condensers, and evaporators. 5. Fire Safety: Fire safety measures, such as proper labeling, training, and emergency protocols, are essential due to the mild flammability of A2L refrigerants. 6. Building Codes and Standards: Adherence to updated building codes and standards, such as CSA B52-2023 in Canada, which includes provisions for A2L refrigerants, is mandatory. 7. Installation and Maintenance: Technicians must be trained in handling A2L refrigerants, including safe installation, maintenance, and repair practices.
