A2L refrigerants are becoming increasingly popular in commercial refrigeration, due to their high energy efficiency and low Global Warming Potential (GWP). A2L refrigerants are classified as having a low flammability risk (by the ASHRAE Standard 34) and can be used in many applications. Here is an A2L refrigerant list of A2l refrigerants that are emerging in the commercial refrigeration industry:
A2L Refrigerant List
1. R448A – This is a blend of HFCs and HCAs, offering an energy efficiency increase of up to 5% compared to other A2L alternatives. It has a GWP of 1473 and is non-flammable.
2. R449A – This is a blend of HFCs and HCAs, offering an energy efficiency increase of up to 8%. It has a GWP of 1725 and is non-flammable.
3. R450A – This is a blend of HFCs and HCAs, offering an energy efficiency increase of up to 10%. It has a GWP of 1290 and is non-flammable.
4. R452A – This is a blend of HFOs and HCAs, offering an energy efficiency increase of up to 10% compared to other A2L alternatives. It has a GWP of 989 and is non-flammable.
5. R454C – This is a blend of HFOs and HCAs, offering an energy efficiency increase of up to 15%. It has a GWP of 385 and is non-flammable.
6. R1234yf – This is a single component HFO refrigerant, offering an energy efficiency increase of up to 20%. It has a GWP of 4 and is non-flammable.
It’s important to note that A2L refrigerants should always be used in accordance with the manufacturer’s recommendations and local regulations. Additionally, when transitioning from an existing system to one containing A2L refrigerants, it’s important to ensure that all components are compatible with the new system.
A2L Refrigerants: Looking Ahead
The emergence of A2L refrigerants in commercial refrigeration is offering a more efficient and environmentally friendly alternative for businesses. This A2L refrigerant list provides just a few examples of A2L refrigerants available on the market, but there may be more options available depending on your specific application.
If you’re considering A2L refrigerants for commercial refrigeration, consult with a qualified HVAC professional to ensure that you select the most appropriate option for your needs. By making the switch to A2L refrigerants in commercial refrigeration, organizations can take advantage of cost savings, improved energy efficiency and a reduced environmental impact.
