  1. Real-time Monitoring and Diagnostic Solution for an HVAC System ECE Team 169 Anthony Bellatoni (ECE) Greg Carmichael (EPhys) Joe Grassi (ECE) Sponsored by: Qualtech Systems Inc. Advisor: John Chandy

  2. Presentation Outline • Project Goals • Explanation of HVAC • ITE’s HVAC • Qualtech • TEAMS-Designer (what is unique?) • TEAMS-RT (Visual studios we will use to develop C++) • TEAMS-RDS • Stored Sensor Values • Limitations • Project Timeline • Project Budget • Next steps

  3. Project Goals • Previous Senior Design Project –Developed Diagnostic Model of the ITEB HVAC System •Fix model to be able to determine points of failure in HVAC system based on values outputted by sensors –Old model only has one VAV • Develop C++ program extract and analyze real-time data from the building sensors • Combine model and code to detect for faults in real-time.

  4. What is HVAC? •Heating Ventilation and Air Conditioning • Heating : Hot water • Ventilation : humidity and air control • Air Conditioning : Removal of heat

  5. ITE HVAC system •Basement (heat exchanger) • Tunnel to COGEN plant • Penthouse (Air handler) •VAV (Variable air volume) • measured on every floor at every point in system

  6. ITE Penthouse Schematics

  7. What is a VAV?

  8. Sensor Values & VAV

  9. Qualtech Systems Inc. •Located in East Hartford, Connecticut • Software for system health management, integrated diagnostics and telemaintenance • Works on any system • help improve equipment productivity •TEAMS - Testability Engineering and Maintenance System

  10. TEAMS Designer • Modeler • Any complex system (MRI, Car, Building etc...) • Designer Maps out possible failures (& consequences) http://tomgpalmer.com/wp-content/uploads/legacy-images/FLASH%20LIGHT.jpg

  11. TEAMS - RDS • Remote Diagnostic Server • Main connection of TEAMS • Generates Tree Diagram (what could have gone wrong because of certain failure) • Possible solutions • With associated cost and time (designer determined) • Stores information gathered for future analysis • TEAMS-KB (knowledge base)

  12. TEAMS - RT • Provides diagnostic in real-time • Takes developed code & sensor values and assigns code to each component of model • each failure will have associated code to determine if it failed or not

  13. Procedure

  14. Project Limitations • HVAC is a complicated Mechanical system • Many possible failures could occur • Cost and Time of each failure • Sensor values are on protected server • Need to obtain access

  15. Project Timeline

  16. Project Budget http://static.seekingalpha.com/uploads/2009/3/4/saupload_mar04_09_bm.jpg http://www.rosemarierealty.com/wp-content/uploads/2012/03/dreamstime_xs_17999966-300x300.jpg http://blog.outreach.com/wp-content/uploads/2011/09/Church-events-on-no-Budget.jpg http://i.crn.com/images/free_cloud_400.jpg

  17. Next Steps • Obtain Real-Time Data from Sensors • Working with Professor Laurent Michel & Schneider Electric • Complete Updated Model • Begin & implement code development
