The heat for a VAV box can typically be a hot water coil or electric heat strips. The minimum airflow setting for this terminal unit will be 75 CFM. The logic behind keeping the box airflow at the maximum is because when heating the air, if you cut the air to the minimum the velocity will be so low that the heated air will never drop down and will just stay near the ceiling. This field is a fraction that... ".. multiplied by the Maximum Air Flow Rate to determine the maximum volume flow rate (m3/s) allowed during reheat operation... ". These units are lined with insulation to provide sound absorption and thermal resistance. A single building can have several hundred VAV boxes and with a DDC system managers can quickly see where problem areas are or change control set points with a few clicks.

Variable Air Volume Systems.
The VAV box is usually allowed to reduce the airflow to zero during periods of no cooling load. Once the room reaches the desired temperature, the damper returns its minimum position. The ductwork, terminal units, duct connections, and ultimately air distribution equipment create a pressure drop that must be overcome by the air handling unit to deliver air. Since there is no reheat coil, shut-off VAV systems do not provide heating capability during periods when the building is occupied. This unit is essentially a single-duct terminal unit with an integral fan chamber mounted on the side, parallel to the primary air stream. Advantages of VAV Systems: • Relatively inexpensive individual room control. VAV:HeatAndCool:Reheat is true shouldn't the air flow for. Dual-duct units are lined with insulation to provide sound dampening and thermal resistance; these units are designed for interior and exterior use. FEATURES AND BENEFITS. If this does not adequately heat the area, a heating coil in the box is energized to provide the required heat.
If this is the case, both selections would be acceptable for the design. I chose to enter the required leaving air temperature (LAT) and it chose a 1 row coil with. Because buildings vary, it is very important to choose a system that is "right" for the facility. With the heat load calculated we can now view the Hot Water performance curves in the catalog to determine what size coil to order. 8 W/ of lighting, and the equipment in the space the max cooling should be 300 ft3/min (CFM). Similar to simple shut-off system, upon a fall in space temperature, VAV systems with terminal reheat reduce the volume of the air to the space. The terminal unit chosen to serve this conference room must be able to deliver a maximum of 300 CFM as well as a minimum of 75 CFM. VAV box reheat airflow setting.
This same unit-mounted heating coil can be used for morning warm-up. This particular VAV box in the picture is not fan-powered. Available in multiple configurations, air terminal units manage supply air from a central air handling station by regulating the volume and temperature of the air.
The controller communicates with the damper to determine the position and the amount of air that goes to the room. Am I just doing a poor job of reading the documentation? This silencer contains baffles made of additional fiberglass insulation surrounded by a perforated metal liner.
Discharge sound is the noise created by the unit that is discharged down the ductwork that eventually reaches the space through the air distribution equipment. Running the fan when heat is required keeps the room air exchange rate constant and at a sufficient volume to maintain good air circulation. Series Fan-Powered VAV. Assured of accurate, AHRI Certified Performance ratings. VAV:HeatAndCool:Reheat increases the air flow to maximum first, then modulates the reheat valve to 100%. The controls that monitor air flow and heating coil are normally linked to the room's thermostat. The total air volume delivered by the terminal passes through either the primary inlet, the induction port, or a combination of the two, with the total air flow discharging through the fan. If what is said about. This reduced temperature is normally maintained somewhere between 55oF and 65oF. The series fan-powered variable air volume box operates much like the parallel box except the fan runs in both the heating and cooling modes.
