Objectives Adiabatic cooling Cooling towers Cycles

Evaporative Cooling (air washing)

Air Washer Sprays liquid water into air stream Typically, air leaves system at lower temperature and higher humidity than it enters

Evaporative Cooler

Air Washers/Evaporative Coolers Heat and mass transfer is mutually compensating Can evaluate based on temperature drop, humidification, or comparison to other energy exchangers

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

Schematic

Solution Can get from Stevens diagram (page 272) Can also be used to determine Minimum water temperature Volume of tower required
