The correct connection for a rupture disc mounted on a centrifugal chiller is to the evaporator. This is because the primary function of a rupture disc is to provide a safety mechanism that prevents overpressure conditions within the system.

In a centrifugal chiller, the evaporator absorbs heat from the designated area to be cooled, causing the refrigerant inside to evaporate. If excessive pressure builds up due to a malfunction or a blockage, it is critical that the weakest point in the system is designed to handle that condition safely. By connecting the rupture disc to the evaporator, any excessive pressure can be released to prevent catastrophic failure of the evaporator or other components.

Connecting the rupture disc to the evaporator ensures that the system can safely vent excess pressure, thereby protecting the chiller and maintaining safe operational conditions.
