According to ComStar, RS-45 is a capacity match for R-22
across the range of applications where R-22 is used. No other refrigerant
mirrors the capacity of R-22 at low temperature (-35°C evap) and high
temperature (7°C evap). Owing to its thermodynamic properties, RS-45 has a
wider application range than R-404A, R-507, R-410A, R-407C and others.
Regarding equipment modifications, only modest
changes to the liquid lines and expansion devices may be required.
