🔍 Key Concepts

• High-pressure cutout switch function and purpose in a refrigeration system • Role of a pressure relief valve and where it normally discharges in a closed refrigeration system • Order of operation for safety devices vs. emergency devices in protecting equipment

💭 Think About

• Think about which device is intended for normal, automatic protection of the compressor when pressure gets too high, and which is intended only as a last resort emergency safeguard. • Consider what would happen to the refrigerant charge and to the environment if it were routinely vented when pressure rises. • Ask yourself: in a properly designed marine refrigeration system, should refrigerant normally be relieved to the atmosphere or returned within the closed system?

✅ Before You Answer

• Verify which device is designed as the primary control to stop the compressor on high discharge pressure. • Check where a relief valve on a marine refrigeration system is typically piped (receiver, condenser, or atmosphere). • Confirm which should act first during a gradual, steady rise in head pressure: the control device or the mechanical relief device.
