    专利说明:

    The invention relates to a jet surface structure for tempering a room with a radiant ceiling panel, which faces the room to be tempered and is connected to a flow-through from a heat transfer medium pipe register, wherein on the side facing away from the temperature to be tempered an absorption layer is provided.
    It is known jet surface structures, which are designed as sheet-like elements and are also referred to as heating / cooling sail, depend on the ceiling of a room to temper this, so cool or heat as needed. In the utility model DE 29 702 313 it is proposed to additionally use such jet surface structures as insulating elements against acoustic influences. For this purpose, an insulating layer of an acoustic absorption material is provided on the side facing away from the space surface of the jet surface. This allows not only to regulate the temperature of the room but also to reduce the noise level in the room.
    In the utility model DE 9 321 610 sound-absorbing lightweight panels are described in which a fluid pipe network is embedded, which serves for heat dissipation and is connected to a coolant source.
    DE 10 2004 018 278 describes a flat arranged cooling or heating blanket with cooling pipes, which are traversed by a liquid. Above the cooling tubes, an air distribution box is provided which has one connection and several outlets. Through the connection, the air distribution box is supplied with supply air, which is passed through the outputs of the air distribution box to air ducts and flows from there to the room. In order to ensure the lowest possible possible distribution of the supply air to the air ducts, the air distribution box is provided with a sound-absorbing lining. Thus, the sound insulation acts exclusively in relation to the supply of air. Since the air distribution box is closed to the environment, this can not cause a reduction in the noise level of the room.
    It is therefore an object of the present invention to provide a beam surface structure of the type mentioned, which allows improved sound absorption within a room, with substantially constant Temperierungseigenschaften the jet surface structure.
    This object is achieved by a beam surface structure with the features of claim 1. For this purpose, it is provided that on the side facing away from the room to be tempered in addition to the absorption layer, an absorption box for sound absorption is arranged, which is filled with a sound-absorbing material and has the side walls, at least two of which are at least partially provided with through holes. As a result, in contrast to a system with only one planar absorption layer, a significantly improved degree of sound absorption (αs) is achieved in the room to be tempered. Sound waves striking the beam surface structure from the space can either enter the absorption box through openings optionally provided in the radiant ceiling panel or, in particular, through the through openings provided in the side walls of the absorption box, in which they are attenuated by the sound-absorbing material.
    In a further development of this idea, it is provided that the absorption box is cuboid and has at least one fully open side. In particular, the underside of the absorption box is completely open. Thus, it is achieved that sound emissions emanating from people or equipment in the room, through openings that may be provided in the radiant ceiling panel, enter the absorption box and be absorbed there.
    In a particularly preferred embodiment, the absorption layer of the jet surface structure is formed as an acoustic fleece. An acoustic fleece is characterized in that even a thin layer achieves a noticeable absorption effect. In addition to the absorption layer, a thermal insulation layer may be provided on the side of the tube register facing away from the space to be tempered in order to minimize the heat transfer in the direction away from the space.
    The sound-absorbing properties of the absorption box and thus the Strahlflächenaufbaus can be significantly improved if the absorption box is filled with insulating wool, especially mineral wool. According to the invention it can also be provided that the absorption box is lined or filled with other acoustic insulation materials and / or with sound-absorbing components.
    In a further development of this idea, the property of the absorption box can be further improved by the absorption box itself consists of a sound-absorbing material, in particular corrugated cardboard. This dampens the noise level even before it enters the absorption box. Additionally or alternatively, the absorption box can be enveloped from the outside with a sound-absorbing material or at least partially covered.
    It has been found to be advantageous if the absorption box has openings in the two longitudinal side walls, which have a diameter of about 5 mm to about 20 mm. Preferably, the openings are arranged in a grid at a distance of about 10 mm to about 50 mm. Particularly advantageous are a hole size of about 10 mm and a distance of the grid of about 20 mm have been found.
    Advantageously, the end walls and the top wall (top) of the cuboid absorption box are closed, i. they have no opening or holes. This prevents the sound waves from leaving the absorption box directly after entering the absorption box. As a result, sound waves in the absorption box can be reflected several times on the end walls and the ceiling wall, whereby a good attenuation of the sound waves is achieved.
    A particularly high degree of sound absorption (αs) can be achieved in that the ratio of the area of the openings of the radiant ceiling panel to the base of the radiant ceiling panel is greater than 0.05, preferably greater than 0.1. A particularly good sound absorption capacity results at a ratio greater than 0.2.
    Surprisingly, even a relatively small absorption box can achieve a high degree of sound absorption (αs). Thus, the ratio of the base area of the absorption box to the base area of the radiant ceiling panel is preferably in a range of greater than 0.05 and less than 0.5. Already in a range between about 0.1 to 0.2, a sufficiently good sound absorption for sports halls can be achieved.
    In a preferred embodiment, the absorption box is arranged at a distance from the free edges of the cover jet plate so that it is not perceived by the room to be tempered as disturbing and is also protected from damage. Particularly preferred is an arrangement in which the distance of the absorption box to the free edges at least equal to the height of the absorption box.
    It is particularly preferred if the sound absorption coefficient (αs) measured according to ISO 354: 2003 in a frequency range between 200 Hz and 5000 Hz is greater than 0.5. In particular, the sound absorption coefficient (αs) in a frequency range between 300 Hz and 2500 Hz is greater than 0.8. Measured according to ISO 11654, the sound absorption coefficient (αs) in a frequency range between 1000 Hz and 2000 Hz is at least 0.85.
    The invention will now be described with reference to an embodiment and with reference to the drawings.
    They show schematically:

FIG. 2 is a sectional view of a jet surface structure taken along section axis II of FIG. 1; FIG.<Tb> FIG. 3 <SEP> a side view of the absorption box without radiant panel and tube register;<Tb> FIG. Fig. 4 is a sectional view taken along the section axis IV of Fig. 3; and<Tb> FIG. 5 <SEP> a diagram of the sound absorption coefficient (αs) of a beam surface structure according to the invention as a function of the frequency.
    Fig. 1 shows a beam surface structure 1 from the side of the room to be tempered ago. You can see the radiating surface of a radiant ceiling panel 2 with openings 3, which are distributed over the entire surface of the radiant ceiling panel 2 in a regular grid. Through the openings 3 sound waves from the room can pass through the radiant ceiling panel 2.
    As the sectional view of FIG. 2 shows, on the side facing away from the tempering space of the radiant ceiling panel 2, an absorption layer 4 is applied, for example. Glued. An absorption box 5 is arranged centrally on the longitudinal axis of the jet surface structure and laterally surrounded by a tube register 6. The pipe register 6 is flowed through in a conventional manner by a heat transfer medium and is for heat transfer in contact with the radiant ceiling panel 2. In the illustrated embodiment, the pipe register 6 is arranged symmetrically about the center M of the jet surface structure.
    At the free edges of the radiant ceiling panel 2 are side plates 7, which extend perpendicular to the temperature-sensitive space facing radiating surface of the radiant ceiling panel 2.
    In Fig. 3 is a side view of the absorption box 5 is shown. This is provided over a majority of the longitudinal side walls 8 with through holes 9. Through the passage openings 9 sound waves that impinge laterally on the absorption box 5, penetrate into this. It can be seen from the sectional view of the absorption box 5 according to FIG. 4 that the absorption box 5 is filled with a sound-absorbing material 10, such as insulating wool. The upper side 11 of the absorption box 5, that is to say the side facing away from the space to be tempered, and the end faces are completely closed in the illustrated example. The underside 12 of the absorption box 5 is completely open and allows contact with the radiant ceiling panel 2 via the insulating layer 4.
    In addition to the absorption layer 4 may optionally be provided on the side facing away from the temperature to be tempered side of the tube register, a thermal insulation layer to minimize the heat transfer in the direction away from the room. The absorption box 5 can be arranged on the thermal insulation layer. The thermal insulation layer can contribute to the sound absorption, but the main purpose is the thermal insulation.
    Fig. 5 shows the sound absorption coefficient (αs) of a beam surface structure according to the invention, depending on the frequency (f), measured according to ISO 354: 2003. For this purpose, a jet surface structure with four radiant ceiling panels, each having a dimension of 1000 mm x 1500 mm x 40 mm, arranged at a height of 160 mm above the floor of a hall with a volume of 204.6 m <3>. On the back of the radiant ceiling panels was a fleece (type AVP 100 Fa. Lantor) attached. In addition, each one filled with mineral wool absorption box of perforated cardboard (hole diameter 10 mm, grid 25 mm) with the dimensions of 150 mm x 900 mm x 150 mm on the radiant ceiling panels was arranged. The radiant ceiling panels consisted of a 0.75 mm thick steel sheet with a hole content of 21%.
    As is apparent from the diagram of Fig. 5, a significant reduction in noise, especially in the most audible for people range of about 2000 Hz to about 4500 Hz, could be achieved.
