What will be replacing R410a?
The refrigerant R410A, which is commonly used in air conditioning and heat pump systems, is being phased out due to its high global warming potential (GWP). As a result, manufacturers are developing and introducing new refrigerants to replace R410A.
Here are some of the new refrigerants that are being developed and tested for use in air conditioning and heat pump systems:
- R32: R32 is a lower GWP refrigerant that has already been adopted in many parts of the world, including Europe and Asia. It has a GWP of 675, which is significantly lower than the GWP of R410A (2088). R32 is compatible with existing air conditioning and heat pump systems that were designed for use with R410A, but it is important to note that some modifications may be necessary to ensure safe and efficient operation.
- R454B: R454B is a low GWP refrigerant that has a GWP of 466. It is designed to be a drop-in replacement for R410A, meaning that it can be used in existing air conditioning and heat pump systems without the need for significant modifications.
- R452B: R452B is another low GWP refrigerant that has a GWP of 676. It is also designed to be a drop-in replacement for R410A.
- R454C: R454C is a new refrigerant that is currently being developed by Chemours. It is designed to have a GWP of less than 150, which is significantly lower than the GWP of R410A. R454C is still in the testing phase, and it is not yet available for use in air conditioning and heat pump systems.
These new refrigerants are being developed in response to regulations aimed at reducing the environmental impact of air conditioning and heat pump systems. The European Union has already implemented regulations that will phase out the use of R410A in new air conditioning and heat pump systems, and the United States is expected to follow suit in the near future.
