AV-100 Series (Bypass Type Variable Air Volume Units)
The Model AV-100 Series is designed to maintain optimum occupant comfort by varying the amount of cold air from the constant volume air handler and bypassing the excess cooling air back to the air handler. The AV-100 Series responds to the thermostat demand for cooling by varying the position of the unit damper, which in turn controls the amount of air entering a zone. During reduced loads, the damper position changes to deflect supply air into the ceiling plenum or return air duct. In this way, the air handler operates at constant volume, while individual zones benefit from increased control of comfort levels.
Savings result from the elimination of variable speed drives for the air handling system fan(s). At reduced zone loads, cool primary air is returned to the air handler via the plenum or return air duct without experiencing zone heat gains.
The lower return air temperature allows the air handler to operate more efficiently.
The AV-100 Series unit comes standard in several different configurations.
• AV-101 – Top Bypass Variable Air Volume Unit (Round inlet – Rectangular outlet)
• AV-102 – Side Bypass Variable Air Volume Unit (Round inlet – Rectangular outlet)
• AV-103 – Top Bypass Variable Air Volume Unit (Rectangular inlet – Rectangular outlet)
AV-100 Series VAV, uses a single actuator-driven primary air damper working in concert with a bypass port balancing
damper. As the primary air damper closes, the bypass port damper opens and vice versa so that a required volume of
air is delivered by the air terminal to the conditioned zone, but in varying amounts of air volumes are delivered to the
room as demanded by the room thermostat.
