Features
R454C was developed as an alternative refrigerant for R404A and R22. Therefore, it is thought that it is used for the condensing unit and the chiller of the low temperature. The advantage is that GWP is low, and it is 1/30 lower value compared with R404A. The temperature glide is slightly larger.
