Definitions

  • the present invention relates to a ceiling mounted device for ventilating rooms and, at the same time, cooling and/or heating the room air, said device including a cooling/heating baffle which has a longitudinal channel for the supply of primary air, a room air cooling/heating coil, a mixing chamber for mixing cooled/heated room air and primary air, means for supplying primary air to the mixing chamber through the medium of an induction effect which serves to suck room air into the device and also to pass said air through the cooling/heating coil, and one or more outlets for a mixture of cooled/heated room air and primary air flowing out from the device essentially horizontally the ceiling of the room.
  • a cooling/heating baffle which has a longitudinal channel for the supply of primary air, a room air cooling/heating coil, a mixing chamber for mixing cooled/heated room air and primary air, means for supplying primary air to the mixing chamber through the medium of an induction effect which serves to suck room air into the device and also to pass said air through the cooling/heating coil, and
  • Cooling baffles Devices of the aforesaid kind are also referred to as cooling baffles or false ceiling panels. Such devices are known for treating room air and are available in different designs, including designs in which natural ventilation generated by a chimney effect is used instead of primary air, although a common feature of those cooling baffles that use primary air of the aforesaid kind is that they include one or more primary air channels to which primary air can be delivered through a central air-conditioning plant installed either in the building concerned or in the proximity of said building, or which is sucked-in from outside by fans provided to this end, so that the pressure in the primary air channel will always be higher than atmospheric pressure. The primary air is blown into the baffle interior through such devices as nozzles for instance, and the influence of said pressure.
  • cooling baffles are lean in energy and do not generate draughts. The level of noise generated is also relatively low.
  • An object of the present invention is to provide a device for cooling and/or heating air in larger rooms or in densely populated rooms, so that ventilation and cooling/heating requirements can both be achieved in the individual case in a simple and effective manner with respect to both installation and apparatus, and also in a manner which is competitive and also attractive from a cost aspect.
  • the invention is characterised to this end by the features set forth in the accompanying Claims.
  • the inventive device includes a baffle in which supply air nozzles are provided for supplying primary air from the primary air channel to the room concerned. These nozzles are disposed in one or more of the baffle walls delimiting the primary air channel.
  • the nozzles can be conveniently turned to enable the air to flow in different directions, essentially transversely to the axis about which the nozzle is turned.
  • supply air nozzles are arranged immediately outside one or both of said outlet openings in the flow direction of the cooled room air/primary air mixture.
  • the device may have different configurations and constructions within the scope of the invention, and may include baffle constructions of an earlier known type combined with supply air nozzles according to the invention, although the device will be described hereinafter with reference to a preferred baffle embodiment.
  • the baffle 10 has a primary air channel 11 to which primary air 12 is delivered from an external source (not shown).
  • the baffle 10 includes an outer casing 13 which delimits the primary air channel 11 outwards, and inner walls 14 which delimit the primary air channel 11 against other parts of the baffle, which include a lower part 15 having a lower plate 16 which forms an outer, lower delimiting wall 17 of the lower part 15 and two outlet channel walls 18 and which together with an upper plate 19 also forms an upper delimiting wall of the lower part 15, said plates preferably being removable.
  • the lower part 15 also accommodates one or more cooling/heating coils 20 mounted in coil holders 21 for cooling/heating room air that flows in through openings (not shown) in the lower wall 17, as shown by arrows.
  • the mixing chamber 23 is arranged above the lower part 15 and is downwardly delimited by the upper plate 19 of the lower part 15 and laterally by parts of the inner walls 14 bordering on the primary air channel 11.
  • nozzles 29 for blowing primary air from the primary air channel 11 into the mixing chamber 23, as shown by arrows, said nozzles being mutually spaced in the longitudinal direction of the baffle 10.
  • supply air nozzles 30 Located immediately outside the exit orifice of the outflow channel 22 are supply air nozzles 30, said supply air constituting in practice the primary air that flows in the primary air channel 11, said nozzles being mutually spaced in the casing 13 in the longitudinal direction of the baffle.
  • the nozzles 30 are mounted so that they can be turned around a vertical axis and therewith enable supply air through the nozzles 30 to be delivered in different directions, according to local requirements and wishes.
  • nozzles 30a of the same kind as the nozzles 30 may be provided at appropriate positions on the baffle 10 adjacent the primary air channel 11. Further nozzles 30b similar to nozzles 30 may be provided in one or in both of the outlet channels 22 with the intention of being mixed with and coacting with the cooled air mixture that flows down from the mixing chamber 23. It lies within the scope of the invention to adapt the number of nozzles 30, 30a and 30b and their positions so as to achieve the best possible comfort in the room, both with respect to ventilation and cooling/heating requirements. In this regard, it may be unsuitable to place nozzles 30 in the lower part of the baffle 10 because of draughts for instance, whereas in other cases a combination of nozzles 30 and 30a or 30b may be preferred.
  • supply air from the primary air channel 11 can also be delivered to the room through nozzles 30a on the upper side or one or both of the vertical side walls of the baffle 11, therewith providing necessary ventilation of the room and also generating a multiple of flow patterns around the baffle 10 without requiring the use of separate supply air devices.
  • the baffle 10 may also be provided with nozzles 30b in one or both outlet channels 22, so that supply air will be mixed with the cooled air mixture prior to said mixture reaching the outlet opening, and therewith enable the outgoing air stream to be controlled to some extent already in the outlet channels 22.
  • the invention enables the cooling/heating requirement of a room to be achieved by dimensioning the length of the baffle, whereas the air requirement can be satisfied with the aid of rotatable nozzles provided in the baffle for supply air from the primary air channel. In many instances, this can result in a shorter length and therewith in smaller dimensions of the cooling/heating baffles and may also replace separate supply air devices, therewith resulting in a more cost-effective solution to the air-conditioning problem for many localities.
