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
