An HVAC Monitoring System in Action
A good example of an HVAC monitoring system in action is the below screenshot from CIM's building analytics system: a faulty Variable Air Volume operation.
A Variable Air Volume (VAV) damper, was fully open but wasn't allowing enough air to flow through as it should. An actuator is a device that operates the damper, so if it's not working properly, the damper won't be able to control airflow correctly, leading to issues with efficiently heating or cooling the space.
Using the building's own data, the PEAK analytics software detected this problem and identified that the cause was a malfunctioning actuator.
Figure 1. Analytics Detecting Faulty VAV operation. VAV damper opens 100% however airflow setpoint is not achieved.
