Recently, we have discussed a new refrigerant called R454B, which is rapidly gaining popularity in the HVAC industry. R454B is gaining momentum because of its lower GWP than R410A and R22 refrigerants. It is an exciting refrigerant with excellent performance capabilities that we want to help our community learn about.

What is R454B Refrigerant?

R454B refrigerant is a hydrofluoroolefin (HFO) refrigerant and the replacement of R410A. It is composed of 69% R32 and 31% one-two-three-four YF. It is classified as mildly flammable (a2l), has a low GWP, and low temperature glide with easy top-off after leaks.

R454B Refrigerant Performance

R454B refrigerant closely matches the performance of R410A and provides superior capacity and efficiency in some cases. It has a much lower GWP than R410A and R22, which makes it an ideal choice for those looking for a more environmentally sustainable refrigerant. The temperature glide is 2.7°F negative, which is low compared to other refrigerants.

R454B Refrigerant vs. other Refrigerants

R454B refrigerant has a much lower GWP than R410A and R22 refrigerants. R454B is another good option if you are looking for a and environmentally sustainable refrigerant instead of R410A, which has a GWP of 2088. R454B has a GWP of only 466, a significant reduction.

Moreover, it is miscible with Poe lubricants, making it easy to use in existing equipment. It also has easy top-off after leaks, making the refrigerant easier to maintain.

Conclusion

R454B refrigerant is an environmentally sustainable refrigerant with excellent performance capabilities. It is rapidly gaining popularity in the HVAC industry because of its lower GWP than R410A and R22 refrigerants. With its comparable performance and superior capacity and efficiency in some cases, R454B refrigerant is worth considering for your AC or chiller equipment.
