Smart Damper That Adjusts Flow Based on Room Needs
The adjusting air volume control valve, often called a VAV terminal, is an electronically controlled device. It automatically adjusts the amount of air supplied to a room based on the room's temperature. When the room becomes too warm, the product allows more cool air to enter. When the room reaches the desired temperature, it reduces the airflow. This keeps each room comfortable while improving overall energy efficiency. That is the smart function of an product.
How This VAV Valve Achieves Precise Control
The adjusting air volume control valve operates through a closed-loop control system. First, a room thermostat measures the current temperature. The built-in DDC controller compares this value with the set point and calculates the required airflow. It then sends a signal to the electric actuator to adjust the valve blades.
Here is the key point: a pressure-independent product includes a built-in airflow sensor. It measures the actual airflow and sends feedback to the controller. The controller then fine-tunes the blade position until the measured airflow matches the required airflow. This continuous feedback is what makes the adjusting air volume control valve highly accurate. The valve can also communicate with the central control system via BACnet or similar protocols.
