404A (R-404A) refrigerant (ASHRAE designation: R-404A [44/52/4]), a near azeotropic blend of HFC-125/HFC-143a/HFC-134a, have been developed and are presented here. These tables …

Similar PT and flow properties to R-502. Higher capacity than R-22, therefore requires TXV change.

There are significant differences between R-502, R-404A, and R-452A, which must be considered when handling, processing, applying, or retrofitting with these refrigerants. These guidelines …
