What is the main purpose of a pressure relief valve in refrigeration systems?

The main purpose of a pressure relief valve in refrigeration systems is to prevent excessive pressure buildup. In the context of refrigeration, maintaining safe operating pressures is crucial for the integrity of the system and the safety of its components. Pressure relief valves are designed to automatically release refrigerant when the pressure within the system exceeds a specific threshold, which helps to prevent potential damage to components such as compressors, pipes, and evaporators that could occur due to overpressure. This function is vital to ensuring that the refrigeration system operates safely and effectively, as excessive pressure can lead to catastrophic failures, leaks, or explosions. By maintaining safe pressure levels, the pressure relief valve plays a critical role in the overall safety and reliability of the refrigeration system.
