A louver blade for a louver assembly includes a first segment and a second segment, where the second segment is adjustable relative to the first segment to selectively contact the first segment, the second segment is configured to reduce an amount of free area between adjacent louver blades of the louver assembly in a first position of the second segment, and the second segment is configured to increase the amount of free area between adjacent louver blades of the louver assembly in a second position of the second segment.

A fan unit a nozzle assembly including a plurality of nozzles configured to receive an air flow and to expel the air flow through a plurality of outlets corresponding to the plurality of nozzles. A controller configured to control a longitudinal movement of a nozzle of the plurality of nozzles based on an operating condition associated with the fan unit.

A damper is disclosed. The damper includes a blade having a slot, a jamb frame member having a hole, and a bearing for connecting the blade to the jamb frame member. The bearing has a first portion receivable in the slot of the blade and a second portion receivable in the hole on the jamb frame member to facilitate rotational movement of the blade.

A damper driving arrangement is disclosed. The arrangement includes an actuator and a torque amplifier. The actuator has a housing for enclosing components of the actuator and an output shaft. The torque amplifier is positioned outside the housing and coupled to the output shaft of the actuator and a driving shaft of a damper. The torque amplifier is configured to amplify torque received from the actuator and transfer amplified torque to the damper.

The present disclosure discloses a louver assembly including a head frame and a sill frame. At least one of the head frame and the sill frame has a channel to drain water. According to another aspect, the louver assembly includes a head frame having a first blade attachment and a sill frame having a second blade attachment. At least one of the first blade attachment and the second blade attachment is configured to connect to one or more blades via welding or fastening means.

A pattern controller for a diffuser including a frame having a first frame member and a second frame member, the first frame member and the second frame member defining an axis A 1 extending there between, a spreader assembly provided between the first frame member and the second frame member, a coupling member provided on the spreader assembly, and a control member coupled to the spreader assembly via the coupling member, where the control member is positioned between the first frame member and the second frame member and configured to angularly displace about the axis A 1 to regulate the throw pattern of the diffuser.

An arrangement for mounting a blower assembly of an HVAC unit. The arrangement comprises a fixture, and one or more support brackets coupled to the fixture and the blower assembly. The one or more support brackets are designed so as to absorb vibrations caused due to operation of the blower assembly or during transportation.

A diffuser assembly for a heating, ventilation, and air conditioning (HVAC) system. The diffuser assembly includes a housing having a wall and a passage formed in the wall. The diffuser assembly also includes a first adjustment panel moveably coupled to the wall and having a first flange and a second adjustment panel moveably coupled to the wall and having a second flange. The first flange and the second flange define at least a portion of an inlet port of the diffuser assembly that extends through the passage. The inlet port is configured to fluidly couple to a duct and direct an air flow from the duct into an interior volume of the housing. The first adjustment panel and the second adjustment panel are configured to translate along the wall to adjust a size of the inlet port.

A diffuser for a heating, ventilation, and air conditioning (HVAC) system includes a housing defining a plenum chamber, where the housing comprises a diffusion plate configured to direct a first air flow into the plenum chamber and to discharge a second air flow from the plenum chamber and a plenum plate disposed within the housing, where the plenum plate extends from a first side of the housing to a second side of the housing opposite the first side, and the plenum plate divides the plenum chamber into a first chamber and a second chamber. The diffuser includes a plurality of apertures disposed along the plenum plate, where the plurality of apertures is configured to direct a third air flow from the first chamber into the second chamber to draw the first air flow into the plenum chamber and to force the second air flow out of the plenum chamber.
