R454b pressure temperature chart
Average coil temp is 15°F. Bubble temp is 10°F. Dewpoint temp is 20°F. The pressure-based PT chart results in the same values but is much easier to use. It more clearly shows that the pressure in the coil is constant (45psig) and that the refrigerant temperature ranges from. 10 °F (when it starts to boil) to 20°F (when boiling is complete).Conclusion. So there you have it – the showdown of R454B vs R410A. Both refrigerants have their strengths and weaknesses, but one thing’s clear: the industry is shifting towards more sustainable options like R454B. While R410A isn’t disappearing overnight, it’s clear that the future of refrigeration is heading in a greener direction.
