The document describes the key components and operation of an ice plant, which uses ammonia as the primary refrigerant and a brine solution of ethylene glycol and water as the secondary refrigerant. The main components are the compressor, condenser, expansion valve, evaporator, ice cans, cooling tower, and pumps. The plant has three separate circuits - the refrigerant circuit with ammonia, the cooling water circuit, and the brine solution circuit which transfers heat from the water to produce ice using the ammonia refrigerant in a closed loop system.

- 5. Ice plant • Ammonia – Primary refrigerant • Brine – secondary refrigerant takes heat from water produce ice • Refrigeration circuit • Cooling water circuit • Brine circuit
- 6. Why do we use brine solution • Primary refrigeranr remain in plant room under supervision • Hazordous ammonia can be used as refrigerant • Provides hold over • Large mass flow rate
