A rupture disc mounted on a low pressure refrigerant recovery container relieves at how many psi?

Rupture discs are critical safety devices used in low-pressure refrigerant recovery containers to prevent overpressure situations. In this context, the correct relief pressure for a rupture disc mounted on a low-pressure refrigerant recovery container is 15 psi. This specification is designed to ensure that excess pressure is safely released before it reaches a level that could compromise the integrity of the container.

The choice of 15 psi is particularly relevant because it aligns with safety standards for low-pressure systems, which typically operate under conditions where pressure variations can occur. This pressure limit helps to prevent potential hazards such as leaks, ruptures, or explosions that could result from the buildup of refrigerant pressure.

In summary, 15 psi is the critical point at which the rupture disc is designed to release, thus providing an essential safety function in maintaining the integrity of the refrigeration system during operation and servicing.
