11.05.2017

A new line of R-452B unitary air conditioning units has been introduced to the US market.

R-452B, a blend of HFC-32, HFC-125 and HFO-1234yf (67/7/26 weight %), having a GWP of 698, is a lower GWP alternative to R-410A (GWP =2,088).

It is mildly flammable, presents around 5 % energy efficiency improvement compared to R-410A, and maintains its performance at high ambient temperatures better than R-410A.

Note : R-452B is considered to be on the lower-flammability side of the 2L spectrum by equipment manufacturers.
