Which risk increases when a refrigeration system's pressure relief valve fails?

💡 Explanation

Refrigerant overpressure cracking becomes more likely because the pressure relief valve remaining closed during an overpressure event prevents discharge enabled by the valve's rupture disk mechanism. Therefore, the system risks structural failure rather than a controlled pressure release.
