What does a pressure relief valve do in a refrigeration system?

A pressure relief valve is a crucial safety component in a refrigeration system, designed specifically to prevent excessive pressure buildup within the system. Its primary function is to open and allow refrigerant to escape when the pressure reaches a certain threshold, thereby preventing potential damage or catastrophic failure of the system.

Maintaining pressure within safe limits is essential for the reliability and longevity of refrigeration systems. High pressure can lead to leaks, equipment failure, or even explosions in extreme cases. Therefore, the pressure relief valve acts as a safety mechanism that ensures the system operates within its designed pressure range, contributing to effective, safe operation.

In contrast, a pressure relief valve does not directly increase cooling efficiency, regulate temperature, or filter contaminants. These other functions fall under different components or systems within refrigeration technology.
