What is the typical design burst pressure for a ruptured disc on a low-pressure centrifugal air-conditioning system?

The typical design burst pressure for a ruptured disc on a low-pressure centrifugal air-conditioning system is set to 15 psi. Rupture discs are safety devices designed to protect equipment from overpressure conditions. They are engineered to burst at a predetermined pressure to prevent catastrophic failure in the system.

In low-pressure systems like those used in many air-conditioning setups, setting the burst pressure to 15 psi ensures a balance between operational safety and system efficiency. If the pressure exceeds this threshold, the disc will rupture, relieving excess pressure and protecting components from damage. The choice of 15 psi reflects industry standards and safety protocols specific to low-pressure applications, aligning with regulatory requirements to ensure reliable operation without risking system integrity.

The other options suggest higher burst pressures that would not typically be suitable for low-pressure applications, as they could fail to activate at the necessary safety levels.
