Chilled water plants are crucial for cooling large commercial, industrial, and institutional buildings. The comprehensive guide to designing a chilled water plant considering in this course are:
Components:
1.Chillers (Electric, Steam, Or Absorption)
2.Cooling Towers
3.Pumps (Chilled Water, Condenser Water)
4.Pipework (Insulated, Sized For Optimal Flow)
5.Valves (Isolation, Control)
6.Heat Exchangers (Plate-and-frame, Shell-and-tube)
7.Controls (Temperature, Flow, Pressure)
Design Considerations:
1.Cooling Load Calculation (BTU/H Or Kw)
2.Chiller Selection (Capacity, Efficiency)
3.Cooling Tower Selection (Size, Type)
4.Pump Selection (Flow Rate, Head)
5.Pipe Sizing and Material Selection
6.Valve Selection (Type, Size)
7.Control Strategy (Temperature, Flow, Pressure)
8.Redundancy And Backup Systems
9.Energy Efficiency and Sustainability
10.Maintenance And Accessibility
