What is the purpose of a pressure-limiting device in a refrigeration system?

The purpose of a pressure-limiting device in a refrigeration system is to ensure safety by monitoring and controlling pressure levels. When pressures reach a predefined threshold, this device automatically stops the operation of the system to prevent damage or failure due to excessive pressure. By halting operation, it protects the system components and reduces the risk of catastrophic failure or hazards such as leaks or explosions. This safety feature is crucial for maintaining the integrity of the refrigeration cycle and ensuring the secure and efficient functioning of the equipment.

While other options mention functions related to pressure management, they do not focus specifically on the automatic stopping aspect that is central to a pressure-limiting device's purpose.
