商品紹介

The variable air volume control damper combines a rectangular galvanized casing, opposed control blades, an averaging differential-pressure sensor and a matched electronic controller-actuator assembly. Pressure measured at several points across the inlet is converted into an airflow signal and compared with the commanded setpoint. The actuator then moves the blade bank until the measured value returns to the required range. Replaceable edge seals and enclosed blade gears support low-leakage shut-off and keep the linkage outside the main airstream.

主要な特徴

Multi-point effective-pressure sensing averages the inlet profile instead of relying on a single pressure tap.

Opposed airfoil blades provide progressive modulation across a broad minimum-to-maximum airflow range.

The controller can accept an analog or digital setpoint for temperature, occupancy or room-pressure sequences.

External electronics, shaft indication and replaceable seals simplify functional checks without removing the damper.

お客様の製品に関する懸念事項

Accurate VAV control depends on a usable sensor signal, stable inlet conditions, correct actuator authority and a minimum airflow that protects the room process.

A single pressure pickup reports an incorrect flow value behind an elbow.An averaging sensor samples several locations and a straight inlet section reduces profile distortion.

The actuator hunts because the controller gain is too aggressive for the duct response.Matched actuator timing and tuned control parameters provide stable movement around the airflow setpoint.

Closing below the validated minimum airflow disrupts room pressure and dilution.Programmable minimum and maximum limits keep the commanded airflow inside the operating envelope.

Blade leakage prevents an unused branch from isolating during setback.Tip and jamb seals combined with opposed blades improve shut-off when the controller receives a close override.
