What is r454b?

R454B, also known as Solstice N13 or Opteon XL41, is a non-ozone depleting hydrofluoroolefin (HFO) refrigerant blend with a low global warming potential (GWP) developed by Chemours. It is a potential alternative to R410A in residential and light commercial air conditioning and heat pump applications.

R454B has a GWP of 466, which is significantly lower than that of R410A (GWP of 2088). This makes it a more environmentally friendly refrigerant option that aligns with global efforts to reduce greenhouse gas emissions and combat climate change.

R454B has similar thermodynamic properties to R410A, which makes it an easy drop-in replacement in existing systems without the need for major equipment modifications. It offers good energy efficiency and performance, making it a viable alternative for air conditioning systems.

However, like other HFO refrigerants, R454B is flammable under certain conditions, so proper handling and storage precautions must be taken when using this refrigerant. It is important to consult with a licensed HVAC professional to ensure the safe and proper use of R454B in air conditioning and heat pump systems.
