ELECTRIC VARIABLE-AIR-VOLUME DIFFUSER

摘要

A variable-air-volume (VAV) diffuser includes a diffuser housing that is formed for coupling to a supply air conduit. The diffuser housing defines a discharging opening for discharge of supply air from the supply air conduit into a room. The VAV diffuser may also include a supporting structure that is affixed to the diffuser housing, and a flow controller for varying the volume of supply air discharged through the discharging opening. The VAV diffuser may further include an electric actuator that is mounted on the supporting structure for moving the flow controller to vary the volume of supply air. The electric actuator may be accessible from room side and removable from the diffuser housing while the diffuser housing is coupled to the supply air conduit, the supporting structure is affixed to the diffuser housing and the flow controller remains within the diffuser housing.
