Project Description:

This project resulted in a PI Processbook troubleshooting graphical display for the HVAC Systems Technician at Algonquin College. This display monitors multiple components of the ACCE Air Handling Unit 6.1. It uses real-time sensor tag values from the college’s Building Automation System to display and compare data. Data is displayed through graphs and labels for easy monitoring and is compared in the VBA editor to trigger flags. The flagging conditions are as follows:

-If the Occupancy is on for more than 24 hours.

-If the lead cooling compressor does not change from week to week.

-If the air temperature increases after cooling.

-If the air temperature is greater than the setpoint by 5 degrees Celsius or more.

-If a cooling coil turns on more than 4 times per hour.

If a flag is triggered, the corresponding LED will turn red which notifies the Technician that something is wrong. By using this display, the Technician can monitor the Air Handling Unit remotely and see when equipment is malfunctioning.

Short Description:

The purpose of this project is to design a Data Visualization graphical display on PI Processbook which uses real-time sensor tag values from the Building Automation System to remotely monitor an Air Handling Unit.
