R-452A saturated pressures are marginally lower than refrigerant R-404A; R-448A/R-449A pressures are slightly lower than R-404A. Compressor standards use dew point temperatures because they allow for a clear correlation between pressures and temperatures.
Pressure/Temperature Chart - Johnstone Supply
Johnstone Supply is a leading wholesale distributor for HVACR equipment, parts and supplies available and in-stock at local branches.
Solstice 452A has a moderate temperature glide between about 3 °K and 4 °K, depending upon pressure. When dealing with blends, pressure-temperature tables are presented with two pressures listed for each temperature: the dew pressure and the bubble pressure. The dew pressure is used for determining the system
