Table 13-2 Low Lift Pump Sizing
13.5.3 Limited Capacity at Low Pressure Ratios
This performance chart ("Figure 13-2 Centrifugal Performance Dynamics") is representative of a
maximum capacity curve that you would see with Turbocor centrifugal compressors. At point A, a
low pressure ratio due to high evaporator load conditions, such as hot building start-up, can limit the
maximum capacity of the centrifugal compressor.
If more capacity is desired, it is advisable to raise the discharge pressure temporarily to increase the
pressure ratio (point B) until the sensible heat in the building is dissipated.
