    Technical area
    The invention relates to a ceiling element for a heating and cooling ceiling and such a ceiling elements comprehensive heating and cooling ceiling. Heating and cooling ceilings of this type are used for air conditioning of rooms, especially in the commercial sector, ie offices, meeting rooms, etc.
    State of the art
    There are already many ceiling elements have been proposed with which in addition to the room and the existing mostly concrete ceiling is cooled, which u.U. allows to reduce the energy consumption, especially during cooling, by using rest periods with low heat load, which usually fall into the night hours with their lower outside temperatures, to pre-cool the ceiling. There are various difficulties to overcome, such as the occurrence of low temperatures at the beginning of an operating phase, usually in the morning and insufficient cooling effect towards its end, usually in the afternoon and evening, which may require energy-intensive countermeasures such as direct heating in the morning and additional later strong direct cooling. Although additional direct cooling is unavoidable in most cases, it is desirable to be able to keep it as low as possible in order to save energy.
    In known generic ceiling elements, the effect of precooling is generally weak, because the ceiling element is spaced from the ceiling and therefore exchanges heat with the underside of the ceiling only by radiation and free convection. The ceiling is cooled only slightly because of the weak thermal coupling to the ceiling element and its effect as a heat sink at times of high heat load is low.
    Such a generic ceiling element, in which the ceiling plate is arranged at a distance below the ceiling, is known from EP 1 422 482 A1. In this ceiling element is also the ceiling only on a circumferential profile, which is thermally connected to the edge of the ceiling plate thermally, while the other parts are the same only on the relatively low heat conduction in the thin ceiling plate itself cooled. For these reasons - insufficient full-surface cooling of the ceiling plate and disturbed by an air gap heat transfer to the ceiling - the effectiveness of the ceiling cooling is not as pronounced as would be desirable.
    In this regard, similar ceiling elements are EP 1 862 742 A1 and WO 2010/034 498 A2 refer.
    From EP 1 167 888 A2 a heating and cooling ceiling is known, in which the ceiling elements cover the underside of the ceiling almost completely. The cables do not run through the ceiling elements, but between them. The ceiling elements each consist of a ceiling plate and a spaced below the same arranged base plate, which are connected at the edges and also thermally coupled together. As a result, the room ceiling inevitably always cooled the room, which can lead to pronounced pre-cooling of the ceiling easily to an initial hypothermia of the room. In addition, the thermal coupling between the base plate and ceiling plate is affected by an arranged between them sound absorbing layer despite the connection of the plates at the edges, so that the thermal connection between the underside of the ceiling and the room rather weaker than in the sense of effective utilization of the precooling Room cover during the rest periods would be desirable. On the whole, usually a pronounced direct cooling during the operating phases will be required, in which inevitably the ceiling is also cooled. Their pre-cooling can on the whole only reduce this Mitkühleffekt, but do not contribute much to the space cooling.
    Presentation of the invention
    The invention is based on the object to improve generic ceiling elements and heating and cooling ceilings to the effect that especially the cooling of the ceiling during rest periods with low heat load, usually during the night, and their utilization during periods of operation with high heat load, usually During the day, more effective and thus the reduction of energy consumption achieved by pre-cooling the ceiling during resting periods is more pronounced.
    This object is achieved by the invention as characterized in the claims.
    Brief description of the drawings
    In the following the invention will be explained in more detail with reference to figures, which represent only one embodiment. Show it<Tb> FIG. 1 <SEP> a bottom view of a top part of a ceiling element according to the invention,<Tb> FIG. 2 <SEP> a plan view of a lower part of the inventive ceiling element and<Tb> FIG. 3 <SEP> a section through the inventive ceiling element along III-III in Fig. 1, 2, in which some parts of lines are omitted.
    Ways to carry out the invention
    An upper part 1 (Fig. 1, 3) of the ceiling element comprises a plurality of spaced substantially in a longitudinal direction substantially flat ceiling panels 2a, b, c, d constant thickness and a ceiling duct, which connects a ceiling supply connection 3 with a ceiling return connection 4 and for the passage of a fluid heating and cooling medium, usually water, is used. Each of the meanders 7 is attached to the underside of one of the ceiling panels 2a, b, c, d and closely adjoins it so that it is good thermal contact is ensured. The branches of the meander 7 are each uniformly distributed over the underside, preferably so that no part thereof is wider than a maximum distance of e.g. 15 cm from the meander 7 is removed. So the entire ceiling plate 2a; b; c; thermally closely coupled to the respective meander 7.
    The ceiling panels 2a, b, c, d each consist of a plastically or elastically deformable material that rests over the entire surface of the underside of an existing concrete concrete ceiling 8, even if it is slightly uneven and has a high thermal conductivity of at least 5 W / mK, preferably at least 30 W / mK. Particularly suitable are ductile metals or alloys such as aluminum or also with materials with high thermal conductivity, e.g. with carbon fiber or graphite, graphite expandate or metal particles, filled good heat conducting plastics. The thickness of the ceiling panels 2a, b, c, d should be low, so that easy deformability and good heat transfer between the meander 7 and the top of the ceiling plate 2a; b; c; d are guaranteed. It is preferably between 0.3 mm and 2 mm. The total area of the ceiling panels 2a, b, c, d in the example is 2.1 m 2. It should be at least 0.2 m <2>.
    The tops of the ceiling plate 2a, b, c, d are each glued to the underside of the ceiling 8. The thickness of the adhesive layer should also be low, preferably 1 mm or less, so that the heat transfer is disturbed as little as possible. The adhesive should have the highest possible thermal conductivity. It may be improved with particles of high thermal conductivity material, e.g. Graphite, graphite expandate or metal particles.
    The adhesive-covered tops of the ceiling panels 2a, b, c, d are pressed against the underside of the ceiling 8 and glued over the entire surface with her, so that the ceiling panels 2a, b, c, d gapless, separated only by the adhesive layer of her , rest against the ceiling 8 form fit. In this way, a very close thermal coupling of the ceiling 8 is achieved on the ceiling panels 2a, b, c, d and on this to the meander 7 of the ceiling duct.
    A lower part 9 (FIGS. 2, 3) which is not directly connected to the upper part 1 comprises a housing made up of three longitudinally successive sections 10a, b, c, each of which being a perforated plate 11 with longitudinal side and in the case of the outer sections 10a , c also transverse closing frames 12 are formed and suspended from the ceiling 8. The adjoining perforated plates 11 together form a flat perforated cover, which closes the ceiling element against the room. A space line which, likewise for the passage of a fluid coolant such as water, connects a room flow connection 13 to a room return connection 14 comprises longitudinal lines 15a, b and meanders 17 connected therebetween through hoses 16 to the same and mutually connected meanders 17 which each extend over an upper surface of a Extend perforated plate 11. The straight sections of a meander 17 lie in guide grooves on the upper sides of parallel rails 18 with flat rectangular contact surfaces, which are glued to the top of the perforated plate 11. Between the rails 18, the top of the perforated plate 11 may each be covered by an acoustic fleece.
    On the space line is a continuous over the surface of the perforated plates 11 insulating layer 19 (Figure 3), which is approximately as a mat of a porous sound-absorbing material, e.g. may be formed from a fibrous material such as glass wool, rock wool or a foam such as melamine or as a flat bag made of textile material or film which is filled with a fibrous material, foam or granules. It may be divided into sections corresponding to the perforated plates 11. The insulating layer 19 thermally insulates the ceiling duct and the ceiling panels 2a, b, c, d thermally from the underside, ie in particular from the room duct and the perforated panels 11. At the same time, it increases the sound absorption of the ceiling element and thus improves its acoustic properties.
    Supply air, which may also be cooled or warmed, can be conducted into the intermediate space between the underside of the ceiling 8 and the insulation layer 19 via an air connection box 20 (FIG. 2), which is then led through recesses at the edge of the insulation layer 19 and the Openings in the perforated plates 11 passes into the underlying space or is passed through openings in folds of the frames 12 against the underside of the ceiling 8 and then sinks into the room.
    The ceiling elements described can be modified in many ways. Thus, they may comprise more or less ceiling panels or perforated panels and the construction of the ceiling duct and the space line may differ from that shown. It is also not excluded to provide no base and to accomplish the direct cooling and heating of the room, if necessary, with other than the means described. In this case, an insulating layer arranged below the ceiling line can nevertheless be provided, which also conceals the ceiling panels and acts as a sound-damping effect.
    The ceiling elements can be used both for heating and for cooling, but is the cooling in the foreground and will be explained in more detail below. Operating phases, usually during the day in which the room is used and the heat load is high, alternate with rest periods, usually during the night when the room is not in use.
    When constructed as described ceiling elements, the ceiling duct and the room line are preferably independent of each other, so that the cooling of the ceiling over the upper part 1 and the direct cooling of the room via the lower part 9 are not coupled together. Depending on the requirements and circumstances, e.g. the room temperature, then the cooling can be divided differently between the upper part 1 and the lower part 9. For example, during a rest phase at a sufficiently low temperature of the room - e.g. not higher than 21 ° C - only the ceiling duct of coolant are flowed through, so that although the ceiling 8 is precooled, but avoiding hypothermia of the room and at the same time energy is saved, while at higher room temperature, the room is cooled directly through the room line.
    But it is also not ruled to put the space line and ceiling duct in series, so the ceiling supply connection 3 with the room return connection 14 or the room flow connection 13 to the ceiling return connection 4 to connect and the distribution of the cooling effect by the flow rate or the flow direction ( Permutation of supply connection and return connection) or both.
    The inventive ceiling elements are suitable for building a novel heating and cooling ceiling, which includes the ceiling 8 and a number of ceiling elements. In this case, the underside of the ceiling 8 is covered only partially, in particular between 20% and 80% of the ceiling elements. These are preferably uniformly distributed over the underside of the ceiling 8, such that no point of said bottom more than 2m, preferably is removed from a ceiling element. In this way, the difficulty, which results from the thermal insulation of the ceiling 8 from the room through the insulating layer 19, bypassed. Namely, when the ceiling 8 during a resting phase on the tops 1 of the ceiling elements in the immediately above the ceiling panels 2a, b, c, d lying areas is strongly cooled so wanders by heat conduction in the ceiling 8 gradually heat from lying between the ceiling elements free Intermediate areas in these areas. The intermediate areas also cool off as a result. During the following phase of operation, they then gradually absorb heat from the space below by radiation and convection, preventing it from being insulated, thus contributing to its cooling.
