Mar 10, 2022 · Learn how a Variable Air Volume System and VAV box's works including VAV Zoning, Static Pressure Sensor use and location for VFD control.

Terminal units reduce energy costs and minimize carbon footprint. Daikin’s single duct VAV boxes, from 80 to 8000 CFM, provide high performance and set the standard in the industry for construction, performance, and quality.

A Variable Air Volume (VAV) box, is a part of an HVAC system in commercial buildings. A VAV box is integral to the ductwork connecting primary ductwork to secondary ductwork. In many cases, a Variable Air Volume box is nothing but an assembly of a sheet metal box with a damper and controls inside a control panel.

A VAV terminal unit, [9] often called a VAV box, is the zone-level flow control device. It is basically a calibrated air damper with an automatic actuator. The VAV terminal unit is connected to either a local or a central control system.

Feb 25, 2022 · VAV (Variable Air Volume) controllers are integral to HVAC systems that require varying cooling and heating loads in different zones. In this article, we will explore some of the most common types of VAV boxes and their specific applications.

ENVIRO-TEC variable air volume (VAV) terminals are among the quietest and most accurate airflow control systems in the industry. The FlowStar™ sensors and unassuming design keep spaces comfortable without distraction, and direct digital controls (DDC) provide consistent and reliable operation.

VariTrane™ variable-air-volume units (VAV) are among the industry leaders in quality and reliability and are designed to meet the specific needs of today’s applications.

Sep 13, 2021 · Variable air volume (VAV) boxes — or duct terminal units — are installed in HVAC ductwork to create heating and cooling zones with independent temperatures.

Johnson Controls offers a variety of variable air volume terminals for HVAC temperature control, air preciseness, and noise reduction to keep you comfortable.

There are two major classifications of VAV boxes or terminals—pressure dependent and pressure independent. A VAV box is considered pressure dependent when the flow rate passing through the box varies with the inlet pressure in the supply duct.
