Definitions

  • the invention relates to a heating and cooling sail, comprising at least one support plate and thus heat-conducting connected channels, which can be traversed by a fluid, and at least one fan with an air outlet surface.
  • Cooling sails have been known for some time from the prior art and are used to dissipate room heat. This is done via the thermally conductively connected to the support plate tubes, which are typically traversed with water as the heat transfer medium, the warm rising room air gives its heat to the cool water.
  • Cooling sails are often combined with ventilation systems, as in the case of cooling a limitation of the room humidity to avoid condensation is necessary.
  • the ventilation systems also influence the flow of cooling sails.
  • the ventilation systems may include, for example, source outlets on the floor, on the wall or on the ceiling.
  • a cooling device for locally cooling a workstation has a housing with a front wall and a rear wall, wherein an interior of the housing is supplied with supply air from an air conditioner. In the interior of the housing Peltier elements for cooling the supply air are arranged.
  • WO 2011/091886 A1 describes a ceiling sail with air outlet, wherein the supply air is deflected from its introduction into the air outlet to the outlet of the same by about 180 °. An overflow of the carrier plate by means of nozzles.
  • a guide element is arranged, which divides a flowing from the fan flow in at least two partial volume flows, of which a partial flow above the support plate and a partial volume flow flows below the carrier plate.
  • the present invention there is accordingly a distribution of the total volume flow leaving the air outlet surface of the fan, which in the cooling case has the effect that the jamming cool air above the support plate is actively moved into the space, whereby the cooling effect can be significantly increased.
  • the partial volume flow which runs below the carrier plate, is led directly into the room, which creates the impression of a fresh air supply due to the air movement.
  • both sides of the support plate are actively flowed over, as a result per se, an increased heat transfer takes place and the performance of the heating and cooling sail is thus increased.
  • the guide element is arranged in a region "in front of" the air outlet surface, it should be understood that the guide element is positioned outside of the fan. In other words, viewed in the direction of flow, the guide element is located behind the air outlet surface, then that the air leaving the fan first passes the air outlet surface before it reaches the guide element.
  • the division of the total volume flow leaving the fan causes the warm air jammed under the support plate to be actively returned to the room increases the heating effect and increases the penetration depth of the hot air in the direction of the floor of the room.
  • the formation of a temperature layer is prevented even without the arrangement of nozzles and there is a uniformly mixed room air.
  • the fan is advantageously a free-blowing fan without housing, so that the overall height of the heating and cooling sail according to the invention remains small. Since the fan is not connected to a primary air supply, it is a pure air circulation system, but it is actively operated. The arrangement of the guide element and the resulting subdivision of the fan leaving the volumetric flow creates a heating and cooling sail with variable applications, which is further characterized by low power consumption and good sound properties, since fans can be used with low pressure increase.
  • the fan is equipped with channels that lead from the fan to the one or more of the respective guide elements of the individual carrier plates.
  • the air outlet surface of the fan is formed by the individual air outlet surfaces of the channels ending in front of the guide element.
  • the guide element may be formed as a simple sheet metal or, for example, as a so-called scoop plate, wherein it may be connected to the carrier plate.
  • a compound of guide element and carrier plate can be done by gluing, welding, soldering, screwing or otherwise.
  • the guide element may also be positioned by means of other means and may be at a distance from the carrier plate.
  • the width of the guide element should be at least or exactly the width of the air outlet cross section correspond to the fan or all fans.
  • the guide element can also be made of plastic or other materials.
  • the guide element can be taken in relation to the distribution of the air outlet surface leaving total volume flow in so far as that the division is influenced by the height to which the guide element protrudes with respect to the height of the air outlet surface. If the guide element leads exactly up to half the height of the air outlet surface, then - assuming the same resistance in both flow paths - there is an exact division of the total volume flow into two equal partial volume flows. Otherwise, the partial volume flows are different in size, wherein the resistors in the respective flow paths also have an influence on the distribution.
  • the distance between an edge of the guide element facing the air outlet surface and the air outlet surface is chosen to be as small as possible. Accordingly, it is conceivable that the guide element directly adjoins the air outlet surface and thus is a distance of 0 mm. In this case, there is an immediate separation of the total volume flow and the partial volume flow flowing under the support plate is optimally guided. If the distance chosen too large, there is a risk that the provided for flow below the support plate partial flow is not performed sufficiently and only partially passes under the support plate. In order not to jeopardize the positive effect of the air duct, the distance should be less than or equal to 200 mm, advantageously less than 100 mm, but better still less than 50 mm, more advantageously less than 20 mm.
  • the fan runs with a lower edge of the air outlet surface below the carrier plate, so that the guide element is formed by the carrier plate. Consequently, it is possible to dispense with a separate guide element, since the total volume flow from the air outlet surface of the fan or the fans is subdivided into two partial volume flows due to the position of the air outlet surface which is offset in height relative to the carrier plate, one of which above the carrier plate and the other below Carrier plate flows.
  • an offset in the cooling sail is visually recognizable on a side facing the space, which is due to the downward projecting position of the fan. For high ceilings, however, such an embodiment may be practical, as offset at high altitude is less noticeable.
  • the fan or the fans is arranged with a footprint on the support plate, so that the air outlet surface of the fan or the fans is located entirely above the support plate.
  • the support plate is in itself sufficiently stable and sufficiently stable connected to the ceiling, in particular suspended, so that the fan can come to rest on the support plate without having to be attached separately to the ceiling.
  • the support plate In order to ensure a flow of the emerging below the guide element from the air outlet cross-section volume flow on the underside of the support plate, the support plate must be at least partially, preferably in a region of a projection of the guide element, perforated or have an opening. In this way, the guided below the guide element partial flow reaches the perforations or the opening on the underside of the support plate and flows along the same.
  • An angle which the guide element encloses with the carrier plate should advantageously have an amount between 3 ° and 25 °.
  • the aforementioned oblique position of the guide element causes, in particular, the lower partial volume flow to flow along the carrier plate.
  • the guide element is adjustable with respect to the angle that it includes with the air outlet surface of the fan.
  • the entire volume flow can be subdivided as desired into different partial volume flows, resulting in different cooling effects or heating effects.
  • the adjustment can be made by a lockable or motor-operated holding element, so that an individual adaptation of the sail to a room or load situation is possible.
  • the carrier plate has perforations or holes which preferably define a free cross section of about 10% to 30% of the perforated or holed total area. In this case, both the entire visible surface or only a part of the same can be perforated. Furthermore, with regard to the acoustics, it may be useful or helpful to provide sound-absorbing elements on or above the carrier plate. In this way, increased requirements in terms of sound insulation can be realized. in this connection is constructive to ensure that a heat transfer from the top of the carrier plate to the ambient air is possible.
  • a particularly preferred embodiment of the invention provides that the at least one fan is a fan with low pressure increase, which is characterized in that it promotes a high volume flow at very low noise. Also, the power consumption is very low.
  • a cross-flow fan can be used.
  • Another advantage resulting from the aforementioned feature is the very low possible height, which has the heating and cooling sail according to the invention. The height of the fan should be in the range between 20 and 80 mm, resulting in a total height of the cooling sail in quasi same size.
  • the at least one fan is equipped with a speed control. This makes it possible to vary the cooling or heating power of the heating and cooling sail, which is expedient in terms of individual adjustability by the user and thus the comfort.
  • At least one cooling register is arranged on the carrier plate in addition to the channels for the heat carrier fluid, an increase in the cooling capacity is made possible and the cooling sail according to the invention can also be used in rooms with high cooling loads.
  • an inventive heating and cooling sail 1 is shown, which is composed of a support plate 2 with a length L and a width and a fan 3 arranged on the support plate 2. Since a vertical section is shown, the width of the support plate 2 is not recognizable. Typically, heating and cooling sails vary in width from 0.6 m to 1.2 m. Other widths are of course conceivable.
  • the length L of the support plate 2 is in the FIG. 1 merely indicated because the heating and cooling sail 1 is not shown in its full length L.
  • the length of heating and cooling sails is also individual and can be between 1 m to 4 m.
  • the support plate 2 is provided with meandering channels 4, in which cooling liquid, such as water, is circulated.
  • the support plate 2 and the channels 4 are thermally conductively connected to each other.
  • the fan 3 is a free-blowing fan 3, which has no housing and sucks in the room air. Accordingly, it is not connected to a ventilation system, so that the heating and cooling sail 1 according to the invention generates an active recirculation mode.
  • the fan 3 is arranged with a footprint 5 on the support plate 2 and with this over not in the FIG. 1 shown fasteners connected.
  • the attachment of the support plate 2 to a ceiling not shown in the figure is carried out as usual in the art by suspension and is in the FIG. 1 also not shown.
  • the fan 3 at a right end of the support plate 2, that is arranged on a short side, wherein the support plate 2 along this short side has a backsplash 6.
  • the fan 3 has an air outlet surface 7, flows out of the previously aspirated room air again.
  • a guide element 9 is arranged, which extends transversely to the air outlet surface 7 and an angle ⁇ of about 80 ° with the air outlet surface 7 includes. Accordingly, an angle ⁇ between the support plate 2 and the guide element 9 is 20 °.
  • a distance a between a fan 3 facing edge 10 of the guide element 9 and the air outlet surface 7 of the fan 3 is 20 mm.
  • the guide element 9 is at its side facing away from the fan 3 edge 10 ', for example, via a weld firmly connected to the support plate 2 and thus not in view of the aforementioned angle ⁇ and ⁇ adjustable.
  • the arrangement of the guide element 9 causes a leaving the air outlet surface 7 of the fan 3 volume flow is divided into two partial volume flows, which are indicated in the figure by two arrows 11, 12, wherein a first, upper partial volume flow (arrow 11) flows above the support plate 2 and a second, lower part volume flow (arrow 12) flows below the support plate 2.
  • a first, upper partial volume flow (arrow 11) flows above the support plate 2
  • a second, lower part volume flow (arrow 12) flows below the support plate 2.
