Where is a rupture disk typically located in a refrigeration system?

In a refrigeration system, a rupture disk acts as a safety device designed to relieve excess pressure and protect equipment from potential damage due to overpressure scenarios. The correct location for a rupture disk is on the cooler of a chiller.

Chillers operate by removing heat from a liquid, typically using refrigerant, and maintaining appropriate pressure levels within the system is critical to ensure efficient operation and prevent failure of the components. A rupture disk being situated on the cooler helps to ensure that if an abnormal pressure condition develops, the disk can burst and safely release refrigerant, thus protecting the entire system from catastrophic failure.

In contrast, while the other locations (compressor discharge line, evaporator coil, and condenser unit) are important components of the refrigeration system, they have other mechanisms and safety devices in place to manage pressure. The rupture disk specifically located on the cooler is crucial for directly managing pressurized refrigerant conditions that could lead to overheating or equipment damage within the chiller's cooling process.
