This performance chart (Figure 13-1) 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.
