Definitions

  • the invention relates to a method for air conditioning a room by means of a ceiling sail, comprising a carrier plate having a length and a width and a distribution channel arranged above the carrier plate, wherein the distribution channel is parallel to a longitudinal axis of the carrier plate and is provided to two opposite sides with outlet openings , so that supply air flows parallel to the support plate and perpendicular to the longitudinal axis of the support plate on both sides out of the distribution channel, wherein on both sides of the distribution channel in each case a heat exchanger is arranged and between the support plate and the distribution channel and between the support plate and the heat exchangers is a distance which defines a free air space above the support plate.
  • Ceiling sails are widely known and serve primarily to conceal a raw ceiling or building services. Furthermore, it is common to use ceiling canopies also for the air conditioning of rooms, for example by being provided on their upper side with an air outlet.
  • EP 1 382 916 A1 proposes a method of the aforementioned type with a distribution channel, which is wrapped with a plastic capillary tube mat as a heat exchanger.
  • a ceiling sail which is composed of a support plate with heat exchanger elements mounted thereon and an air passage arranged on the support plate.
  • the air passage is arranged at one end of the support plate and blows to a supply air via a nozzle along the heat exchanger elements and the other supply air along the underside of the support plate, so that incoming air enters directly into the room.
  • the above object is achieved in that the supply air flowing from the distribution channel induces the room air in the free air space, which then enters the heat exchanger, is tempered and then mixed with the supply air to a mixed air stream.
  • the distribution channel and the adjacent heat exchangers are thus arranged at a distance from the carrier plate, which can be achieved for example by the arrangement of suitable spacers.
  • the carrier plate is elongated and therefore has a greater length than width.
  • the supply air guide is centered and in the longitudinal direction of the support plate, ie also in the longitudinal direction of the ceiling sail.
  • the distance between the carrier plate and the heat exchangers and the distribution channel should advantageously be greater than 50 mm, since thus a sufficient cooling capacity is ensured. Further preferably, the distance should be at least 60 mm, more preferably at least 70 mm.
  • the distribution channel can be regarded as a pressure channel, which blows evenly over its entire length, the supply air through the outlet openings. Temperature control thus takes place along the two longitudinal sides of the ceiling sail, whereby the effectiveness of the air conditioning is increased enormously.
  • the support plate it is advantageous for acoustic reasons, if it has perforations or holes, preferably a free cross-section of about 13% to 19%, more preferably 16%.
  • the support plate can therefore be formed by a perforated plate.
  • an acoustic mat can be placed on the perforated plate.
  • an acoustic mat can serve, for example, a bubble foam or a foam with one-sided applied film. But there are also other types of acoustic mats conceivable.
  • the distribution channel has in each case a series of mutually spaced outlet openings on its two opposite sides, so that a uniform outflow of supply air is ensured over the entire distribution channel and on both sides.
  • the outlet openings may be formed as round holes, oval holes, slots or otherwise. Furthermore, it is conceivable to design the outlet openings as nozzles.
  • outlet openings it is furthermore particularly advantageous if they are arranged above an upper edge of the heat exchanger. In this way, above the heat exchangers, a kind of mixing space is created in which the supply air mixes with the tempered room air to form a mixed air.
  • the heat exchangers extend substantially over the length of the distribution channel. Essentially in this context means that the length of the heat exchangers may differ by 10% with respect to the length of the distribution channel, both positive and negative.
  • the longitudinal sides of the heat exchangers viewed in a projection each jump back relative to the corresponding longitudinal side of the carrier plate, preferably by 15 to 25% of the width of the carrier plate.
  • a free space in which the mixed air flows As a result, a reverse induction of the mixed air is avoided.
  • the return one easier secondary flow of the secondary air achieved.
  • the appearance of the return of the heat exchanger is advantageous because the viewing angle is flatter and the heat exchangers are thus less visible.
  • the distance between the carrier plate and the distribution channel is smaller than the distance between the carrier plate and the heat exchangers.
  • a fan is arranged in the distribution channel or in a connecting connection connected thereto, by means of which supply air is advanced, a pressure channel is created in a simple manner.
  • the support plate is 10 to 30% longer than the distribution channel, the length of the support plate being the reference.
  • the distribution channel and the heat exchangers are accommodated in a common housing and form an induction unit. This is very helpful especially for the installation of the ceiling sail.
  • the room air is heated by the heat exchanger before entering a mixing room.
  • the mixing room does not have to be a delimited space, but rather an area.
  • FIG. 1 a ceiling sail 1 is shown in a cross section, from which the basic structure of the same is clearly visible.
  • the ceiling sail 1, which is attached to a ceiling of a space R, not shown, has a support plate 2, which is elongated and thus has a longer length L and a shorter width B.
  • a longitudinal axis 3 of the support plate 2 is in the FIG. 2 indicated by a dashed line 4.
  • the support plate 2 is canted up at its edges C-shaped and thus has a circumferential ridge. 5
  • a rectangular distribution channel 9 is arranged, which is fed via a supply air connection nozzle 10 with supply air.
  • the supply air may be primary air in the form of outside air.
  • a series of mutually spaced outlet openings 12 is provided on both longitudinal sides 11 of the carrier plate 2.
  • the outlet openings 12 can be formed by induction nozzles.
  • the heat exchangers 13 On both sides of the distribution channel 9, a heat exchanger 13 is provided in each case.
  • the heat exchangers 13 have a height h which corresponds to only about half the height H of the distribution channel 9, so that the supply air flowing out through the outlet openings 12 comes into fluid communication only with the upper side of the heat exchanger 13. A flow through the heat exchanger 13 by the supply air is not provided.
  • the heat exchangers 13 may be copper-aluminum heat exchangers.
  • the heat exchanger 13 and the distribution channel 9 are arranged in a common housing 14 and form in this way an induction unit 15.
  • the housing 14 In the upper region, ie in the fluidic escape of the outlet openings 12, the housing 14 on both sides of a protruding nose 16, so that an upper side of the housing 14 is wider than a lower side thereof.
  • the induction unit 15 is arranged by means not shown in the figure spacers so that a distance a between the bottom of the induction unit 15, ie the bottom of the distribution channel 9 and the two heat exchangers 13, and the support plate 2 consists. In the FIG. 1 the induction unit 15 is thus arranged on a plane which corresponds approximately to the plane of an upper side of the webs 5. This is indicated by a dashed line 6 in the FIG. 1 shown. If the dashed line 6 is included in the consideration, the carrier plate 2 with its webs 5 results in a channel 8 which is open in the region of the lines 6 and into which room air is induced.
  • the support plate 2 consists either of a substantially airtight material, such as sheet metal, or of a perforated plate with an acoustic mat lying thereon.
  • the distance a corresponds to the clear height of the free air space 7 and is in the present case 60 mm, but may vary depending on the application. A modification of the distance a is possible at any time by the spacers, not shown in the figure, on which the induction unit 15 comes to rest, are exchanged accordingly.
  • the Indian FIG. 1 shown cross-section clearly shows that the width B of the support plate 2 is greater than a maximum width b of the induction unit 15 at its top.
  • the induction unit 15 thus jumps back relative to the support plate 2, wherein the distance A from one longitudinal side 11 of the support plate 2 to an upper edge side 20 of the housing 14 is about 20% of the width B of the support plate 2.
  • the distance A 'from the longitudinal side 11 of the carrier plate 2 to a lower edge side 21 of the housing 14 is greater and amounts to approximately 25% of the width B of the carrier plate 2.
  • FIG. 2 is a plan view of the ceiling sail 1 is shown, from which it can be seen that the induction unit 15, which is composed of the distribution channel 9, the two heat exchangers 13 and the housing 14, extends over a majority of the length L of the support plate 2.
  • the length of the induction unit 14 is about 90% of the length L of the support plate 2, wherein the induction unit 14 each jumps back by about 5% at both ends of the ceiling sail 1.
  • the ceiling sail 1 shown is attached at three points by means of suitable fastening means 23 to a ceiling of the room R, not shown. If the length L of the ceiling sail 1 is less than 2.4 m, it is sufficient to attach the ceiling sail in two places by means of fastening means. With a length greater than 2.4 m, three places are needed, on which fasteners to be ordered. The same applies to lengths exceeding 2.4 m.
  • FIG. 3 shows a side view through the ceiling sail 1, from which in particular the row of outlet openings 12 clearly shows.
