Kyle Loo Home Institution: University of Hawaii @ Manoa 2008 Akamai internship at Submillimeter Array (SMA) Mentor: Billie Chitwood Air Handler System Model
SMA Project Description Background Design Construction Test Conclusion Acknowledgments Outline
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
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 Purpose: Use as a test model Debug Saves time Project Description :
First Design: Second Design: Preliminary Designs:
Fabrication • Air Handler/Mixing Box • Two 4 inch Intakes holes • 2.5 inch Rear exhaust which enters into the Cabin
Heater Installation Temperature sensors Solid State Relay Heater
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 • 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 • Stable after one and half hours
Conclusion • Air Handler Model • Used for testing purposes • Useful for future hardware and software upgrades • Great Experience • Design • Fabricate • Test
