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

ITE Penthouse Schematics

What is a VAV?

Sensor Values & VAV

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

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

Procedure

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

Next Steps

• Obtain Real-Time Data from Sensorso Working with Professor Laurent Michel &

Schneider Electric

• Complete Updated Model

• Begin & implement code development
