Frequently Asked Questions
What is the saturation pressure of R-32 at 80°F?
At 80°F, R-32 has a saturation pressure of 247.0 PSIG.
What is R-32 used for?
R-32 (difluoromethane) is a lower-GWP refrigerant used in residential and light commercial air conditioning systems. It has a GWP of 675, which is about one-third of R-410A, making it a more environmentally friendly option.
Is R-32 flammable?
R-32 is classified as A2L (mildly flammable). It has a lower flammability than many other alternatives and requires specific safety measures during handling, but its burning velocity is very low.
