Table 3. Q4SA Cooling Charging Charts
Heat Pump in Cooling
* Note: All pressures are listed in
psig. and all temperatures in deg. F.
— Shaded Boxes indicate flooded conditions
— Rated Design Values. Suction Pressure will be lower than design value if indoor air
flow, entering dry bulb, or entering wet bulb temperatures are lower than design.
— Discharge temperatures greater than charted values indicates a refrigerant
undercharge.
