Project Background<\/strong><\/h2>\n\n\n\n

Baltimore Aircoil Company (BAC) manufactures cooling towers, which they test within a lab at their facility in Jessup, Maryland. To generate the most accurate and useful results, they wish to maintain a constant wet bulb temperature within the lab during a test. However, as the test is run, the cooling tower emits large amounts of warm humid air, which accumulates within the lab and creates an ever-changing wet bulb temperature. Currently, technicians are tasked with manually controlling two sets of fans, and three sets of dampers to manage the lab environment.<\/p>\n\n\n\n

Problem Statement<\/h2>\n\n\n\n

\u201cDesign an Automated Airflow Management System Capable of Maintaining a Set Wet Bulb Temperature Within a Thermal Lab.\u201d<\/em><\/p>\n\n\n\n

Requirements<\/h2>\n\n\n\n

1 – Maintain a wet bulb temperature at +\/- 1 \u00b0F from the setpoint.<\/p>\n\n\n\n

2 – Design must deliver consistent lab environments between 60 \u00b0F and 82 \u00b0F wet bulb temperature.<\/p>\n\n\n\n

3 – Design must function for a 39\u2019 4\u201d W x 67\u2019 4\u201d L x 34\u2019 H lab but be scalable for different size labs.<\/p>\n\n\n\n

4 – Design must be suitable for all sizes of testing units, from 4\u2019 x 3\u2019 to 14\u2019 x 24\u2019 in footprint.<\/strong><\/p>\n\n\n\n

5 – Design must control the following equipment by the stated inputs:<\/p>\n\n\n\n

  • 1x VFD for 2 Exhaust Fans: Eaton SVX9000 (0-10V and 4-20mA)<\/li>
  • 2x Mixing Fans: 15 Hp 3 Phase Electric Motors (No VFD)<\/li>
  • 6x Dampers: Belimo AFB24-SR motor (24VAC 0-10V)<\/li>
  • 6x Damper Position Controllers: SGA24sr (24VAC 0-10V)<\/li><\/ul>\n\n\n\n

    6 – Design must be simulated to prove it is capable of meeting requirements prior to prototyping.<\/p>\n\n\n\n
