Definitions

  • the present invention relates to a ceiling-mounted device for ventilating rooms and, at the same time, cooling or heating the room air, of the kind appearing from the preamble of the following patent claim 1.
  • One object of the present invention is to provide an improved ceiling-mounted device with freely hanging baffle of the kind mentioned by way of introduction, which is not afflicted with the drawbacks previously occurring.
  • the device according to the invention offers a smaller overall height than could be achieved with previously known freely hanging baffles, at the same time as the outflow of conditioned air takes place close to and along the ceiling. Even the implied problem of crossing air streams can be completely avoided.
  • Recirculating air (warm) is here completely separated from the mixture of recirculating-/primary air (cold).
  • Previously known freely hanging devices involve problems with crossing airstreams which create turbulence, as inflowing warm recirculating air, flowing upwards along the vertical side of the baffle, is forced to pass (cross) a horizontally outflowing mixture of cold primary air/recirculating air from the vertical side of the baffle.
  • a smaller overall height is required due to the fact that the baffle advantageously can be mounted snug against the ceiling.
  • the air throw for conditioned exhaust air mixed with primary air is prolonged due to the fact that the air mixture can be blown out along with and directly bearing on the ceiling.
  • a prolonged air throw increases the intermix of room air, which will bring about a lesser risk of draught due to a more efficient use of ceiling and walls.
  • Figs. 1- 4 show schematic diagrams of four different preferred embodiments of the invention of which Fig. 1-2 show devices with two triangular primary air channels and one element arranged vertically and parallel to the ceiling adjacent each primary air channel, and Figs. 3- 4 show different variants which could be of current interest with a single element arranged horizontally between the two primary air channels.
  • Figs. 1 and 2 show a device according to the invention with a freely hanging baffle 6 seen in cross-section, which baffle 6 is provided with an upper part 8 and a bottom part 9 and is arranged close to a ceiling 10 and which baffle has two longitudinal primary air channels 11,11' and two elements 12 for cooling/heating of room air. Between each element 12 and the adjacent primary air channel 11,11' there is a mixing chamber 13 with an outlet opening 15, said mixing chamber 13 being intended for mixing of primary air, which has been supplied through primary air supply means 17 of the primary air channels and through the medium of an induction effect by means of this primary air sucked-in room air, which has passed the element 12, and doing so has been cooled or heated depending on the predetermined serviceability of the device.
  • a distribution chamber 19 is indicated in which the room air is distributed all over each element 12 before passing it.
  • the device is supplied with primary air through the channels 11,11' with such energy that it through the medium of an induction effect, i.e. causing a negative pressure or vacuum to occur in the mixing chamber 13, will suck in room air from below into the baffle 6, as the arrows 20 indicate.
  • This room air is subsequently sucked horizontally in both directions through the respective element 12 and into the corresponding mixing chamber 13, where it meets and gets mixed with primary air supplied by the means 17, which can be formed as nozzles 17, slots 17' or the like.
  • the air conditioned and mixed in this way is blown out through the openings 15 close to the ceiling 10 and in horizontal direction as shown by the arrows 21.
  • All the devices according to Figs. 1- 4 have a baffle 6, elements 12 for cooling/heating, mixing chambers 13, primary air supply means 17, outlet openings 15 and a distribution chamber 19.
  • the mixing chambers 13 are arranged at the side of or obliquely above the elements 12, while the distribution chamber 19 is arranged between or below said elements.
  • the primary air supply means 17,17' are arranged in mutually opposite, in the embodiments triangular primary air channels 11,11'.
  • the triangular shape of the channels essentially corresponds to a right-angled triangle and the channels are arranged with their hypotenuses facing each other and the catheters constituting vertical and horizontal sides, respectively, of the baffle 6.
  • the nozzles 17 or slots 17' are arranged close to the bottom side of the baffle 6 and so directed that primary air supplied therethrough flows upwards along the hypotenuses or oblique walls 22 of the channels towards the outlet openings 15.
  • the negative pressure or vacuum is produced which is required to make possible that room air 20 will be sucked in via the distribution chamber 19 and through the respective element or elements into the mixing chambers 13 to be mixed with the primary air, and finally, as shown by the arrows 21, flow out through the outlet openings 15 at the underside of the ceiling 10.
  • the room air may be led into the distribution chamber 19 by the fact that its bottom part 9 is formed as a perforated sheet, a screen gear or is provided with one or more slots. This is shown in the figures by means of a dashed line.
  • the baffle 6 can be placed close to the ceiling, which is indicated in Figs. 1, 2 and 4 or freely hanging down, as shown in Fig. 3.
  • the top portion of the mixing chamber can with advantage consist of the ceiling 10.
  • the baffle 6 may also comprise a separate top portion 24, which is mandatory in the case of the freely hanging down embodiment but even might be used for baffles intended to be arranged close to a ceiling.
  • two elements 12 are arranged vertically at the oblique or inclined sides or walls 22 of the respective primary air channels 11,11'.
  • the inlet and outlet sides of the elements 12 are vertically arranged, which means that the outlet sides of the elements constitute a vertical delimitation of each mixing chamber 13 while their inlet sides vertically delimit a distribution chamber 19 between each other.
  • the mixing chambers 13 merge into each other at the upper side of the element while the distribution chamber 19 is situated between the underside (inlet side) of the element 12 and the bottom part 9 of the baffle.
  • nozzles 17 may naturally be applied to the embodiments according to Figs. 2-4, and vice versa.
  • the baffle 6 of the embodiments according to Figs. 1, 2 and 4 may also be provided with such a separate top portion 24, as is illustrated in the embodiment according to Fig. 3.
  • the device according to the invention is provided with two primary air channels, it is possible to achieve the required flow capacity with a baffle height less than 100 mm.
