Definitions

  • This invention relates to a supply air device. More specifically, it concerns a supply air device, having an elongated body and being at least partially perforated over its external surface.
  • Typical applications include slot diffusers, tray diffusers, swirl diffusers, and diffusers provided with jet nozzles.
  • Supply air devices of the above type can be used for bringing overheated air down to the public area, for example in shopping malls, indoor sports arenas, and industrial facilities.
  • the shortcomings of swirl diffusers and tray diffusers include the breadth of a blow pattern generated by the diffusers and the inability to redirect the blow pattern during the life cycle of a ventilation system. Such a need to modify ventilation may come up for example in the process of redoing a shop layout.
  • the slot diffuser establishes a narrow blow pattern and a long casting distance.
  • the narrow blow pattern is particularly important when overheated air is delivered for example into a space between chest freezers in a shop. In the event that the blow pattern of a supply air device spreads out, the warm air flow falls on chest freezers, resulting in frosting, ice-forming, and unnecessary energy consumption.
  • the blow pattern of slot diffusers involves the same problem as swirl and tray diffusers, i.e.
  • blow patterns thereof cannot be changed.
  • the shop layout undergoes several changes during its life cycle, and a situation is often encountered in which the supply air devices are located unfavorably, for example with respect to the location of chest freezers.
  • a solution to the problem has been sought by outfitting the premises with jet diffusers, whereby the blow pattern can be redirected as desired.
  • a drawback with jet diffusers is, however, the inability thereof to provide a long casting distance or a narrow blow pattern.
  • This object can be achieved according to the invention by means of a supply air device, having an elongated body and having its bottom perforated and at least some of the apertures fitted with jet nozzles.
  • the supply air device according to the invention is characterized by what is defined in the characterizing clause of the appended independent claim 1.
  • Fig. 1 shows an elongated supply air device 1 in a side view.
  • the supply air device 1 consists of an elongated body 2, whose first end 3 is attachable to a ventilation duct (not shown in the figure) by way of a joint 4.
  • a second end 5 of the supply air device 1 is perforated and thereby the ventilation duct air is delivered into a space surrounding the supply air device.
  • Fig. 2 shows the perforated second end 5 of the supply air device 1.
  • the guide nozzles 7 can be stationary, but from the standpoint of adjustability and versatility it is preferred that at least some of the guide nozzles 7 be adjustable for enabling their blowing direction to be changed. Positioning the adjustable guide nozzles 7 along or in the vicinity of a periphery of the end 5 enables influencing, by changing their blow direction, also the direction of an air flow coming through the ordinary apertures 6. Thus, the entire air flow coming out of the end surface can be pointed in a desired direction and the blow pattern shaped as desired.
  • the aperture system 6 is only sketched over a segment of the end surface, but the extent of aperture system is arbitrarily optional and so is the disposition and number of the guide nozzles 7.
  • the direction of an air flow coming from the guide nozzles 7 can be adjusted freely both by rotating the guide nozzle in the plane of a mounting surface and by a relative change of alignment in the direction of a mounting surface diagonal. This enables pointing the air flow in any direction from the plane of the surface.
  • the guide nozzles 7 shown in fig. 2 are only designed to be mutable in the mounting plane, whereby the direction of a flow pattern established by one guide nozzle changes as determined by the lateral face of a cone.
  • the diverse guide nozzles 7 according to the prior art are always capable of establishing a desired direction of flow.
  • the guide nozzles are preferably made in plastics, thus being easy to press with their engagement tabs into the apertures 6 provided therefor and to pivot in a desired direction.
  • the directionally adjustable guide nozzles 7 can be installed directly as such in the aperture 6 of the supply air device 1 or are installed in a separate adapter element (not shown in the figure) made of an elastic material, which also seals the resulting joint.
  • the blow pattern can be changed and adjusted as desired also by covering some of the apertures 6 or the guide nozzles 7 by fitting the same with plugs 9. Thereby, even during a ventilation cycle working at a reduced performance, it is possible to obtain a sufficiently extensive and effective blow pattern in a ventilated space. By plugging some of the apertures 6 or the guide nozzles 7, it is also possible to make a difference in the obtained blow pattern. Likewise, varying the size and shape of the apertures 6 and the guide nozzles 7 enables obtaining a versatile blow pattern. If desired, the guide nozzles 7 can be replaced for example with another model for influencing the amount of air coming through the guide nozzles. Likewise, the ordinary apertures 6 can be fitted with discs 10 of a washer type, which reduce the size of an original aperture and diminish the throughput of air.
  • the terminal 1 can have its blow pattern adjusted precisely to a desired size and length by changing the ventilation performance or by opening/closing some of the apertures 6 by means of the plugs 9, as well as by directing and shaping the blow pattern by means of the guide nozzles 7.
  • Fig. 2 shows an elongated supply air device 1 circular in cross-section, but it should be appreciated that the supply air device can have an arbitrarily optional cross-section, being for example a square, a rectangle, a triangle, an ellipse, or any other such geometric shape.
  • the apertures 6 may come in various shapes and even the guide nozzles 7 can be shaped for example like polygons, thus being directed in a stepwise manner.
  • Fig. 3 shows the supply air device 1 more precisely in a side view.
  • the supply air device 1 has also a side surface 11 of its body 2 at least partially covered with apertures.
  • the apertures 6 can be equipped with air directing fixed or mutable guide nozzles 7.
  • the air flow regulation can be conducted by means of plugging both some of the apertures 6 and some of the guide nozzles 7 or by downsizing the aperture system.
  • the side aperture system can also be closed completely, whereby the entire air flow can be delivered out of the end 5 of a supply air device.
  • Fig. 3 shows an aperture 6 and guide nozzles 7 for visualizing the same in just a specific area of the side surface 11, but the number of disposition thereof can be selected freely as required by necessary ventilation.
  • the air flow discharging from the end 5 of the supply air device 1 can also be influenced by the guide nozzles 7 mounted on the side surface 11 of the supply air device, which are capable of controlling the direction of a flow coming by way of the end.
