1. Objectives Finalize AHU processes
Compare Cooling towers with humidification

5. From Previous classes: Evaporative Cooling (air washing)

6. Cooling Tower
Similar to an evaporative cooler, but the purpose is often to cool water
Widely used for heat rejection in HVAC systems
Also used to reject industrial process heat

8. Cooling Tower

10. Solution Can get from Stevens diagram (page 272)
Can also be used to determine
Minimum water temperature
Volume of tower required
Can be evaluated as a heat exchanger by conducting NTU analysis
