What is the primary function of a ruptured disc in low-pressure chillers?

The primary function of a ruptured disc in low-pressure chillers is to protect the system from overpressurization. Ruptured discs are safety devices designed to rupture at a predetermined pressure, providing a fail-safe way to relieve excessive pressure that could otherwise lead to system damage or even catastrophic failure. This mechanism ensures that, if the pressure exceeds safety limits—often due to malfunctions or blockages—the disc will break and allow the refrigerant to escape safely, preventing potential hazards such as explosions or leaks.

Maintaining safe operational conditions is crucial in refrigeration systems, particularly in low-pressure systems, where pressure management is essential for efficiency and safety. Therefore, understanding the role of the ruptured disc underscores the importance of such safety components in maintaining system integrity and protecting both equipment and personnel from harm.
