What is a common type of pressure relief device used in large refrigeration systems?

A spring-loaded device is a common type of pressure relief device used in large refrigeration systems due to its reliability in maintaining safe operating pressures. The spring mechanism allows the valve to open at a predetermined pressure to relieve excess pressure, protecting the system from potential overpressure scenarios that could lead to equipment damage or failure.

In refrigeration systems, maintaining appropriate pressure levels is crucial for efficient operation and safety. Spring-loaded pressure relief valves are designed to respond quickly to pressure changes, and they automatically reset once the pressure drops to a safe level. This characteristic makes them ideal for systems where pressure fluctuations may occur.

Additionally, spring-loaded devices tend to have fewer moving parts and can be more durable and easier to maintain compared to other types of relief devices, contributing to their prevalence in industrial applications, including refrigeration.
