Understanding why cars use R1234YF requires more than saying that it is “newer” than R134A. Automakers needed a refrigerant that could sharply reduce the climate impact of mobile air conditioning while still working within compact, high-performance vehicle systems. R1234YF, also written R-1234yf, emerged as one of the principal answers because...

R448A and R449A are two lower-GWP refrigerant blends commonly used in commercial refrigeration systems as alternatives to legacy refrigerants such as R404A and R507. Because they are used in similar low- and medium-temperature applications, many contractors and facility managers ask: what is the difference between r448a and r449a? The short...

R507 is a hydrofluorocarbon refrigerant blend commonly used in commercial refrigeration systems that require reliable low- and medium-temperature cooling. It became popular as a replacement for older ozone-depleting refrigerants, especially R502, and has been widely used in supermarkets, walk-in freezers, cold storage facilities, food service equipment, and industrial refrigeration applications....
