Each VAV box can open or close an integral damper to modulate airflow to satisfy each zone’s temperature setpoints. In some cases, VAV boxes have auxiliary heat/reheat (electric or hot water) where the zone may require more heat, e.g., a perimeter zone with windows. Some features of a VAV system include the following:
ELECTRIC HEAT The electric heater provided with most single duct VAV boxes is essentially a rated duct heater installed in an elongated single duct unit. This longer unit provides for developed flow, after the damper, and a relatively uniform airflow across the coil elements. At low flows, however, there is both a minimum airflowCarnes variable air volume terminal units accurately regulate airflow for maximum occupant comfort. Terminal Units are built to provide low pressure drop and sound levels which are certified by ARI.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.

SDR, SDL EH SDR terminals are available in cooling only, cooling with hot water or electric reheat offerings. SDR Single Duct VAV Terminals are available in ten unit sizes providing airflow capacities between 30 to 8,000 CFM's. Normal: The zone heating airflow will equal the minimum airflow defined by the Clg VAV min field. If the user has specified % Clg VAV min limit, the zone airflow will use the sensible heating equation to solve for volume so long as the heating airflow is not lower than the minimum limit set.If the calculated heating airflow is lower than the minimum limit, the heating .Variable Air Volume or VAV Boxes is the most common method employed in commercial/institutional buildings and is both an effective and economical means of temperature control by Regulating the Air Flow. AV systems have proven to be highly energy efficient in providing an optimal indoor climate. The latest standards and requirements for energy . There are 2 types of VAV boxes in my buildings, one is a series unit, fed w/24v., only power needed is for the damper motor. The other is called a parallel box, these units have the same 24v. damper motor, but fed with 277v., which powers the reheat (duct heater) and a fan, which operates on heat only, with a separate non-powered damper.
Pneumatic VAV Boxes with Electric or HW Reheat Coils. When setting the minimum air volume using the thermostat: First set min air flow and next about one degree less, the electric or HW coil is to activate.
