AZ-20 (R-410A) pressure is about 60% (1. - Manifold sets must be 800 psig high-side and 250 psig low-side with 550 psig low-side retard. It also creates opportunities to rethink the ways of designing cold room. Use a charging hose to connect the system‘s low-pressure port to the low-pressure port (14) of the DMG-5. , seal replacement) or expansion device adjustments may be required in some applications. The manifold cannot be used with ammonia (NH3 / R717). Genetron Properties Suite provides results in tabulated form (exportable to Excel) and in diagrams you are used to (Pressure-Enthalpy, Temperature-Entropy). Dew Point is described as the saturated vapor pressure, or the pressure/temperature at which the first drop of liquid condenses from a vapor. *Standard Cycle 105 F Condenser, 25 F Evaporator, 10 F Subcooling & 10 F Superheat Capacity (%) Capacity (%) 0 0 -5 -5 +5 +5 +15 +15 -15 -15 +25 +25 -25 -25.
