1. SMART Telecomm Ambient Air Cooling System Team 5.1: Justin Alms, Ramon Benitez, Jennifer Pahnke Sponsor: Dr. Wilson Poon Advisor: Dr. James Glancey System Operation The Programmable Logic Controller (PLC) collects and uses sensor data to adjust the fan, valve, and heaters to manipulate the temperature and relative humidity of the air inside the electronic enclosure. The Programmable Logic Controller (PLC) collects and uses sensor data to adjust the fan, valve, and heaters to manipulate the temperature and relative humidity of the air inside the electronic enclosure. SYSTEM HOT: Create an open system SYSTEM HOT: Create an open system Lowering Heater Output, Bring in Cool Ambient Air, and Increase Fan Speed SYSTEM COLD: Create a closed system SYSTEM COLD: Create a closed system Recirculate Warm Air, Decrease Fan Speed, and Turn on Heaters ConceptSubsystems System Control PLC PLC Warnings Warnings Valves Valves Data Acquisition Data Acquisition Enclosure Air, Water Tight Air, Water Tight Positive Pressure Positive Pressure Small as Possible Small as Possible Fan Sensors Recirculation Heat Source Green = Clean Filtered Air Yellow = Air being Warmed by Electronics Red = Hot Air to be Vented or Recirculated Air Mixing Project Concept Statement Project Concept Statement Modern telecomm base stations are packed with sensitive electronics and amplifiers that generate significant amounts of heat. The project goal is to design, build, and evaluate a modular cooling system that incorporates a GORE-TEX® membrane filter and maintains the temperature and relative humidity inside an outdoor electronics enclosure.
