Definitions

the present invention relates to a cover for an air diffuser comprising a mounting plate configured for mounting the cover to an air diffuser base such that the cover is positioned at some distance from the air diffuser base and to an air diffuser base.
the present invention further relates to an air diffuser, air diffusing system and method for controlling the air flow in an air diffusing system.
Air diffusers for air diffusing systems are well-known in the art.
such air diffusers comprise an air diffuser base part (also known as damper body part) with a cover (or damper disc) adjustably mounted thereon.
the air diffusers in the art may have a conical air channel and a substantially conformant conical shape on the cover.
the cover is typically adapted mountable so that the cover can be threaded into a compatibly threaded hole of the air diffuser base.
the rotation of the cover allows the flow cross section between the air diffuser base and the cover to be adjusted larger or smaller, whereby the volumetric rate of the in- or exhaust air passing there through may be controlled.
the present invention now provides an air diffuser having optimal air flow characteristics.
the present invention provides hereto a cover for an air diffuser comprising a mounting plate configured for mounting the cover to an air diffuser base such that the cover and the mounting plate are positioned at some distance from the air diffuser base, wherein the cover further comprises an air flow controller moveably connected to the mounting plate for controlling the flow of air in the air diffuser. It was found that by providing the cover of the present invention, the air flow path of the air diffuser base may be substantially free of any air flow disturbing obstacles.
the air diffuser base can be free of any further air flow controlling adjusting means connected to the internal shaft of the air diffuser base.
the air flow controller may be adjusted by manually moving the air flow controller by the user (e.g. air diffusing system installer), preferably the mounting plate may be provided with one or more air flow controller adjusting means for adjusting the position of the air flow controller relative to the mounting plate.
air flow controller adjusting means may include adjusting means for manually or automatically adjusting the position of the air flow controller.
the cover may comprise a drive unit, such as an electrical actuator like a servomotor, for actuating the air flow controller adjusting means.
a drive unit such as an electrical actuator like a servomotor
the cover may comprise a drive unit, such as an electrical actuator like a servomotor, for actuating the air flow controller adjusting means.
the air flow controller adjusting means are preferably connected to handling means for handling the air flow controller adjusting means.
the handling means may include outwardly protruding handles or lever actuator extending from the edge of the cover.
the air flow controller and the air flow controller adjusting means are provided with cooperating screw threads, wherein the screw thread of the air flow controller adjusting means is connected to rotating handling means, such as a rotatable disc.
the rotatable disc may have similar dimensions of the mounting plate of the present invention.
the rotatable disc may be provided with protrusions which protrusions cooperate with indentations provided in the mounting plate defining a plurality of defined positions of the rotatable disc and, consequently, a plurality of defined positions of the air flow controller, i.e. a plurality of defined air flow rates.
the user may be able to adjust the air flow of an air diffusing system based on data comprised in a look-up table.
the cover of the present invention may be provided with one or more spacers for mounting the cover to an air diffuser base at some distance from the air diffuser base.
the cover may comprise three spacers.
the cover may, instead of being provided with one or more spacers, also be provided with one or more spacer receiving means for receiving spacers provided onto the air diffuser base.
the cover of the present invention may further be provided with a locking mechanism having a first position for locking the position of the air flow controller and a second position for unlocking the position of the air flow controller.
a locking mechanism having a first position for locking the position of the air flow controller and a second position for unlocking the position of the air flow controller.
the air flow controller of the cover of the present invention is configured for cooperation with the surface of an air diffuser base.
the air flow controller is cone-shaped.
the shape of the air flow controller is preferably designed using computational fluid techniques.
the present invention relates to an air diffuser base for an air diffuser comprising one or more mounting elements for mounting the air diffuser base to a cover such that the cover is positioned at some distance from the air diffuser base, and wherein the air flow path of the air diffuser base is free of air flow disturbing obstacles.
the air flow path of the air diffuser base is defined by the inner structure part of the air diffuser base, i.e. the flow path followed by the air inside the air diffuser base.
the air diffuser base of the present invention herewith provides the most optimal, controllable and highly predictable distribution of an air flow through an air diffusing system.
the air diffuser base of the present invention is able for design of an air flow system having an air flow rate of about 50 to 75 m 3 /h at an air pressure loss of at most 10 Pa, more particular an air pressure loss of about 7-9 Pa. Consequently, the air diffuser of the present invention is suitable for providing high air flow rates without producing high at a low level of noise, i.e. at most 30 dB(A), preferably less than 25 dB(A) or even less than 20 dB(A).
the air diffuser base may comprise one or more fixing elements.
the fixing element may be in the form of a sleeve provided with clamping elements wherein the air diffuser base may be form-fittingly clamped into the sleeve.
the one or more mounting elements of the air diffuser base may comprise spacer receiving means for clampingly receiving cooperating spacers of a cover.
the air diffuser base may be provided with spacers wherein the cover is provided with spacer receiving means.
the present invention relates to an air diffuser comprising the air diffuser base of the present invention connected to the cover of the present invention.
the air diffuser of the present invention differs from the air diffusers disclosed in the art in that the air diffuser base may be free of any air flow disturbing obstacles.
the present invention results in an air diffuser system, wherein the air flow rates through the air ducts of the system are better to predict with high reliability.
the present invention further relates to an air diffusing system comprising an air duct, wherein at least one end of the air duct is connected to the air diffuser of the present invention.
the present invention relates to a method of controlling the flow of air in an air diffusing system, comprising the steps of:
Air diffuser 1 comprises cover 10 and air diffuser base 30.
Cover 10 comprises mounting plate 12 provided with three spacers 22.
Air flow controller 14 is moveably connected to mounting plate 12 by air flow controller adjusting means 16, depicted in figure 1 as screw threads 20, 20', in further connection to handling means 18, depicted in figure 1 as a rotating handling means, like a rotatable disc.
Cover 10 is further provided with locking mechanism 24 for locking and unlocking the position of air flow controller 14.
protrusions 26 provided in mounting plate 12 for cooperation with indentations (not shown) provided in handling means 18.
air flow blocker 28 for directing the air flow.
Air diffuser base 30 comprises three mounting elements 32 depicted in figure 1 as spacer receiving means 36.
the spacer receiving means 36 of air diffuser base 30 are configured to clampingly receive spacers 22 of cover 10.
Air diffuser base 30 is further provided with fixing elements 34 for fixing air diffuser base 30 in an end of an air duct. It is noted that the air flow path 38 is free of any air flow disturbing obstacles.
the air diffuser base 30 comprises sleeve 40 for receiving base element 42.
the air diffuser base 30 may further comprise air sealing members 44, 46.
FIG 2 shows an exploded view of cover 10.
the indentations 26' provide in handling means 18 are visible.
the indentations 26' cooperate with the protrusions (not shown) provided in mounting plate 12.
handling means 18 are provided with resistance elements 26" for cooperation with mounting plate 12.
