  1. Challenger Center Cooling Tower Enev/Ench 435 September 23, 2008 Performed By: Dianah Dugan Alex Saputa

  2. Contents • Block Diagram • Schematic • Equipment • Data Collection • Results • Conclusion

  3. Block Diagram of Cooling Tower Air Outlet DH >0 P= 1 atm W= 0 Air Air Inlet CTunit Chilled WS DH <0 CW Chilled WR

  4. Cooling Tower Schematic from Side View Exhaust B Exhaust A Outside Intake OutsideIntake Inside Intake Outside Inlet B Outside Inlet A Inner Inlet B Inner Inlet A

  5. Schematic of Exhaust Fan 0.22 ft 0.72 ft 1.22 ft *Distances measured from center of fan

  6. Equipment • Anemometer • Yard Stick • Ladder • Sling Psychrometer • Psychrometric Chart

  7. Radial Dependence of Temperature for Week 1

  8. Radial Dependence of Temperature for Week 2

  9. Average Air Velocity for Week 1

  10. Average Air Velocityfor Week 2

  11. Calculating the Cross-Sectional Area r1= 0.22 ft r2= 0.72 ft r3= 1.22 ft r4= 1.30 ft r1 r2 r3 r4 R1 R2 A1= π*(R2² - R1²) A2= π*(R3² - R2²) A3= π*(R4² - R3²) R3 R4

  12. Formulas To Solve: • Volumetric Flow Rate = cross-sectional area* measured velocity • Mass Flow Rate = volumetric flow rate * density • Heat = mass flow rate * change in enthalpy • Density is found by taking the inverse of Humid Volume, found on Psychrometric chart

  13. Comparative Volumetric Flow for Each Exhaust Fan

  14. Mass Flow Rate Per Fan

  15. Calculating Enthalpy from Psychrometric Chart

  16. Enthalpy for Inlet and Exhaust Fans

  17. Heat Generated

  18. Change to bar graph***

  19. Conclusions • Velocity is the least in the center of the exhaust

  20. Comments
