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.

What is HVAC?
•Heating Ventilation and Air Conditioningo Heating : Hot watero Ventilation : humidity and air controlo Air Conditioning : Removal of heat

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

TEAMS Designer
• Modelero Any complex system (MRI, Car, Building
etc...)
• Designer Maps out possible failures (& consequences)

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

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

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