93. The rupture disc on a low-pressure centrifugal refrigeration unit is used as an overpressure protection device and is set to relieve at 15 psig and is most likely to lift when the compressor is idle. Where is the rupture disc located?

The rupture disc on a low-pressure centrifugal refrigeration unit, set to relieve at 15 psig and most likely to lift when the compressor is idle, is located on top of the chiller evaporator shell to protect this vessel from overpressure during idle warm-up.
