BRINGING FAULT DETECTION & DIAGNOSIS INTO THE MAINSTREAM

IT'S AN ALERT!

(Service Engine Light for your AC unit)

WHAT IS FDD?

MISSION

The goal of the project is to demonstrate the technical and economic feasibility and environmental impacts of Automated Fault Detection and Diagnosis (FDD) Tools and Technologies for retro commissioning and continuous commissioning of HVAC-R systems.

SCOPE

The project will span 3 years and the team will evaluate FDD technologies at several sites in Connecticut. The study will evaluate the value proposition, market barriers, technical capabilities, installation and support processes, and energy savings. The project team will produce training and education materials to expand the use of FDD technology.

Why FDD in HVAC&R?

HVAC = over 30% of all energy commercial building costs

Refrigeration = ~15% of enegy in restaurants and ~50% in supermarkets

Common Faults

- Restricted indoor and outdoor airflow

- Incorrect refrigerant charge

- Refrigerant line blockage

- Malfunctioning expansion device

- Compressor valve leakage

- Non-condensable gases

- Short cycling

- Economizer Faults
