Fault Event
The fault detection system flagged abnormal cooling output from AHU-1, located in the facility’s mechanical room. It immediately notified the HVAC team of the irregular performance.
Resolution
Upon investigation, the HVAC techs discovered that the main chilled water valve was not operating as needed. The motor actuator controlling the valve had failed. While awaiting replacement, the valve was manually adjusted to ensure temperature comfort.
A new actuator was installed within a few days, restoring full functionality.
Takeaways
The HVAC fault detection system delivered valuable insight into the unit’s performance, enabling a quick response and repairs without disrupting operations or compromising indoor comfort.
Issues like this are extremely difficult to detect without a smart fault detection system. Without it, problems can go unnoticed for years, leading to excess energy consumption, fluctuating temperatures and humidity, occupant discomfort, and operational disruptions.
