Project Description








submillimeter array
Submillimeter Array
  • 8 movable antennas
  • Detects light colors
    • 0.3 – 1.7 mm Wavelengths
  • Air Handler
    • Constant Temperature
    • 2 Valves
      • Cold & Recirculation
    • 4 of the 8 antennas are upgraded currently
project description

Design and Build smaller Air Handler and cabin for testing purposes

Design Requirements:

Accurately simulate Air Handler

Use main components

Be operated by original software


Use as a test model


Saves time

Project Description :

  • Air Handler/Mixing Box
  • Two 4 inch Intakes holes
  • 2.5 inch Rear exhaust which enters into the Cabin
heater installation
Heater Installation

Temperature sensors

Solid State



modification of intake valves
Modification of Intake Valves
  • 4 inch dryer vent
  • Enlarge one axle hole
  • Damper motor turns 3/5 inch round bar
    • Notched at one end to hold valve in place when operating
shop vac modification
Shop Vac Modification
  • Universal Motor
    • Able to use voltage regulator to control speed
  • 4 inch adapter on the exhaust side to be able to match with 4 inch intake valves
  • Temperature and Humidity Sensors
test data analysis

Test/Data Analysis

  • Stable after one and half hours
  • Air Handler Model
    • Used for testing purposes
    • Useful for future hardware and software upgrades
  • Great Experience
    • Design
    • Fabricate
    • Test
  • I would like to thank the following:
    • Mentor – Billie Chitwood
    • John Cheng, Kevin O’Cconnell, and Mac Cooper.
    • All of the SMA staff for using their tools, material, and facilities.
