Definitions
- the present disclosure relates to ventilation systems, and in particular to terminals of such ventilation systems.
- Ventilation systems for buildings comprising ventilation ducts are widely known.
- the ventilation ducts may be integrated in wall and/or ceiling portions.
- the ventilation ducts are provided with terminals such as covers, vents and/or baffles to direct and/or diffuse air flows from the ventilation ducts.
- terminals such as covers, vents and/or baffles to direct and/or diffuse air flows from the ventilation ducts.
- traditional terminals drafts and accumulation of dirt tend to occur, which is undesired.
- a terminal for a ventilation duct of a ventilation system comprises a rear wall defining a ventilation opening for an air flow of the ventilation system and it comprises a luminaire . At least part of the luminaire is located in front of the rear wall, spanning the ventilation opening to control, in particular guide and deflect, an air flow from the ventilation opening and to cover and obscure the ventilation opening.
- the luminaire By arranging the luminaire over the ventilation opening, the luminaire may be cooled by the passing air flow, extending lifetime of a lamp in the luminaire. Conversely, the air flow may be heated by a burning lamp in the luminaire and thus reduce cold drafts.
- the integration of a luminaire in the terminal the number of objects in a space in a building may be reduced and locating of luminaires and ventilation around the building space may be facilitated, as both light and ventilation are generally required in locations close to people, e.g.
- the luminaire is at least partly, preferably fully, recessed in the terminal.
- contact of the air flow with the luminaire increased, improving heat contact and -exchange.
- turbulence of the air flow is induced improving mixing of the air and reducing drafts.
- air turbulence may cause dropping and/or deposition of impurities entrained in the air flow, which therefore may be localised in a predetermined space in or near the terminal and reduce
- the luminaire may be configured to laterally deflect the air flow from the luminaire and against an interior side wall of the terminal so that turbulence within the terminal may be promoted.
- the terminal comprises side walls extending from the rear wall and defining a front plane of the terminal, the rear wall defines the ventilation opening spaced from the side walls by a first distance, the luminaire comprises a front wall being located in front of the rear wall to deflect an air flow from the ventilation opening, and the front wall is recessed in the terminal, being spaced from the side walls by a second distance less than the first distance and spaced from the front plane by a third distance equal or larger than the second distance.
- the terminal provides a space in front of the front plate for air mixture.
- the luminaire may be recessed quite deep into the terminal, improving heat exchange with the air and reducing its visible volume.
- the first, second and third distances may prevent a straight line of access and sight to the ventilation opening from the front plane, so that only generally parallel plates may be visible and the terminal may provide a certain clearly visible depth, facilitating cleaning of the terminal and providing a generally pleasant appearance to the terminal. It is noted that a connection of the ventilation duct to the terminal may be at the rear side of the terminal (see below) and/or at a lateral side thereof.
- the terminal may comprises a flow controller, e.g.
- a predetermined air flow may be provided.
- Baffles that are unitary with the rear wall may reduce weight, increase stability and robustness, reduce manufacturing cost and/or reduce noise.
- the ventilation opening and/or the flow controller may be adjustable, possibly remotely adjustable, so that the air flow can be adapted to circumstances. Remote adjustability facilitates adjustment. Adjustment mechanisms may be visible or hidden from view, e.g. by the luminaire.
- the luminaire comprises a first plate providing the rear wall and a second plate being positioned separate, spaced from and in front of the first plate,
- the design and manufacturing of the terminal are simplified, in particular in case the first plate comprises the flow controller and one or more lamp holders are integrated in or attached to the second plate.
- the luminaire may comprise an adjustable lamp holder and/or optical element for directing emitted light, which may be adjustable remotely.
- light distribution such as spot lighting may be provided as desired.
- the terminal in particular the luminaire, may be water resistant for use in possibly wet locations such as bath rooms.
- the terminal may be used for an air flow from the ventilation opening through the terminal to a building space or in reverse for an air flow from a building space through the terminal to the ventilation opening, e.g. to accommodate excess air and/or for an aspirating system of a ventilation system.
- a further aspect relates to a building.
- the building comprises a ventilation system comprising a ventilation duct for an air flow.
- the ventilation duct is provided with a terminal as disclosed herein.
- the terminal may be at least partly recessed into a ceiling or wall of the building.
- the terminal may protrude and invade little into a space to be ventilated and illuminated such as a room, a hallway or another building compartment. Further, deposition of dust etc. on an outside wall of the terminal may be reduced.
- Such embodiment may be particularly suitable when the ventilation duct is at least partly embedded in or positioned behind the ceiling or wall of the building.
- the ventilation system comprises plural ventilation ducts provided with such terminals as
- the ventilation system may comprise an impeller, e.g. a fan, for forced air flow through the ventilation duct, enabling reaching of predetermined ventilation rate and/or flow
- the forced air flow may be directed out of the duct, e.g. for blowing an air flow into the building, or into the duct, e.g. for aspirating air into the duct.
- the ventilation system may be configured for balanced
- the ventilation system may comprise an air conditioning system such as a control system for at least one of air
- conditioned air may be provided to the building and/or properties like heat or humidity may be harvested from aspired air and energy and resources may be spared.

- Fig. 1 shows a building 1 with a ceiling 2 and having a ventilation system 3 comprising ventilation ducts 5, 7 and an impeller 9 connected with a ventilation duct 5 for generating a forced air flow in the duct 5.
- the exemplary ventilation ducts 5, 7 are embedded in the ceiling 2.
- the ventilation ducts 5, 7 are provided with terminals 10, here being mounted to the ceiling 2 as an example.
- Figs. 2-6 are different views of a terminal 10. A

Relative position and orientation terms “upward”, “downward”, “below”, “above”, and the like in this text relate to the embodiments as shown and oriented in the drawings, unless otherwise specified.
- the terminal 10 comprises a housing 11, here in the form of a rectangular box formed by a segmented rear panel 12 bounding an opening 14 for connection to the ventilation duct 3, 7, and by side walls 16, 18.
- the terminal 10 further comprises a luminaire 20 recessed in the housing 11.
- the shown terminal 10 has a rear side RS and a front side FS, and the side walls 16, 18 define a front plane FP of the terminal 10, which here is completely open.
- the shown exemplary luminaire 20 comprises an optional first plate 22 and a second plate 24.
- the first plate 22 provides a rear wall in the terminal 10 defining a ventilation opening V.

- a ventilation duct may be connected with the terminal 10 on a lateral side of (a housing of) the terminal, relative to the front side FS and back side BS .
- the second plate 24 is separate from the first plate 22 and
- the first plate 22 may be referred to as rear plate 22 and the second plate 24 may also be referred to as front plate 24.
- the second plate 24 spans the ventilation opening V and extends laterally outward from it, covering the ventilation opening V in X and Y directions and obscuring the ventilation opening V against visibility.
- the first and second plates 22, 24 are parallel (and parallel to the XY-plane) .
