  1. ME 414: Project #1 • Design Team Members: Andy Cash Kyle Bredehoeft Alan Koers Brent Miller • Presentation Date: May 5, 2006

  2. Project Definition • NASA Requests a quote: • To design a heating and ventilation system for an arctic research facility located at the North Pole. • Contains four researchers • Inside temperature to be maintained at 25 °C • Outside temperature is a constant -40 °C • No cooling system needed for obvious reasons

  3. Design Constraints • Ducts formed from rubber coated sheet metal: • Sheet Size: 70” x 90” • Relative roughness: 2mm • Outside Walls 12” thick • Inside Walls 8” • Register location is fixed • Register Size: 6” x 16” • Occupants Require 8 liters of fresh air per minute

  24. 800 CFM Flow Trajectory

  25. 800 CFM Flow Trajectory

  26. 800 CFM Pressure Dropand Air Changes per Hour

  27. Blower Comparison • Note: • 2000 CFM Blower vel_max exceeds 100 m/s • Fresh Air Delivery Insufficient

  28. Blower Operation Cost/Month

  29. Monthly Heating Requirements & Costs • Note: • Total Bldg Q=14,651 BTU/hr • Basement not heated

  30. Risk Assessment and Contingency High Impact Low Event of Furnace or Blower Failure High Likelihood • Gather at Central Bldg Location • Start Generator and Resistance heater Low

  31. Risk Assessment and Contingency High Impact Low Fresh Air Ventilation System Frost or Other Blockage High Likelihood • Remove Blockage • Insure Safe Oxygen Levels Low

  32. Cost Summary

  33. Questions • Special Thanks to: Billy Holland Professor Toksoy
