R449A

R449A is a HFO blend refrigerant suitable for use in low and medium temperature applications.

R449A was developed as a lower GWP alternative to R404A, R507, R407F and R22.

R449A has a slightly higher GWP than R448A.

 

Characteristics

• As a retrofit replacement for R404A in supermarket applications, R449A delivers a reduction in power consumption and a significant reduction in carbon footprint in low and medium temperature applications
• R449A is a good alternative to R404A in both low and medium temperature supermarket applications as it has a higher capacity and 5 – 10% better energy efficiency than R404A
• Polyolester oil is required with R449A to ensure adequate oil return
• Existing TX valves may operate satisfactorily with R449A, superheat adjustment will be required. Where practical an electronic expansion device should be considered
