WebFirst, the transcritical boosters (BB, BB + PC, BB + PC + GEjs) present maximum operating pressures in the evaluated range near 100–106 bar. Next, the cascaded R744 subcritical booster systems present a maximum working pressure below 67–72 bar. Finally, the cascade solution has a maximum R744 working pressure below 35 bar. WebCritical Pressure for various refrigerants are: Freon - 11: T cr = 385.12 K, P cr = 44.66 bar, Freon - 12: T cr = 471.1 K, P cr = 41.36 bar, Freon -22: T cr = 369.02 K, P cr = 49.9 bar, Ammonia: Tcr = 405.4 K, Pcr = 113.33 bar ∴ Ammonia has the highest critical point pressure.
