Definitions

  • the invention relates to a Klimadecke according to the preamble of claim 1 and method for its operation.
  • Such Klimascken are each for air conditioning a room, usually for cooling, u.U. but also used for heating.
  • the invention is based on the object to improve known generic Klimacomb to the effect that even with strong pre-cooling of the ceiling in the room to be air-conditioned no disturbing cold air currents occur. This object is solved by the features in the characterizing part of claim 1.
  • the advantages achieved by the invention are also that relatively cold supply air can be supplied, which not only enhances the cooling effect, but also causes the water vapor content of the supply air and thus the indoor air is low. This, in turn, makes it possible to additionally cool in addition, if necessary, e.g. by cooling fluid without condensation occurred.
  • a Klimadecke arranged on the underside of a ceiling 1, which covers a room to be air conditioned, which comprises a plurality of equal and each at the same height with distance of the ceiling 1 elongated cooling elements 3, which are arranged at a distance next to each other and each extend substantially over the length or width of the space 2, wherein each cooling element 3 may consist of several successively arranged modules.
  • the cooling elements 3 can cover, for example, between 30% and 50% of the underside of the ceiling 1.
  • two damping elements 5, each separated by a gap are arranged in each case for sound damping, which are likewise suspended at a distance below the ceiling 1 and extend over the length or width of the space 2.
  • the damping elements 5 may each comprise a cuboid housing made of perforated sheet metal, which is filled with a sound-damping material such as rock wool or glass wool. They only partially fill the spaces 4, preferably at most 20%, so that they are at least 80% empty and air can circulate easily.
  • the cooling element 3 has ( Fig. 2 ) in each case an approximately cuboidal housing with a constant, approximately rectangular cross-section, which preferably consists of metal, for example substantially of aluminum It comprises a plane Ceiling 6, the top of which forms a directed against the ceiling 1 cover surface 7 and side walls 8a, b.
  • an air supply duct 10a, b is airtightly separated from the remaining interior of the housing, which forms a central exhaust area 11, on each side.
  • the supply air ducts 10a, b are each connected at one end of the cooling element 3 to an air supply line (not shown). At the wise they each have in the longitudinal direction of the cooling element 3 at regular intervals successive outlet openings 12, which are up against the ceiling 1 and form over the length of the cooling element 3 extending air outlet.
  • the take-off region 11 is connected to an air outlet (not shown) at one end of the cooling element 3 and closed at the bottom by a perforated base plate 13 which together with the laterally adjoining housing parts bounding the supply air ducts forms a flat underside of the cooling element 3
  • the base plate 13 may be made of aluminum or steel. Its perforation may consist of apertures distributed in a uniform grid over base plate 13, for example, equal round holes with a diameter of e.g. between 0.5mm and 2.5mm, where the free cross-section can be between 0.5% and 20%.
  • the top of the base plate 13 may be covered with an acoustic fleece.
  • branches of an upper line 14 are mounted near the intermediate walls 9a, b at the bottom of the ceiling, which at one end of the cooling element 3 with a cold water supply or a (not shown) and at the opposite are connected so that the upper line 14 can be flowed through by cooling liquid.
  • the upper conduit 14 is thermally coupled closely to the ceiling 6 and thus to the top surface 7.
  • branches of a lower conduit 15 are also attached to the upper surface of the base plate 13 such that the lower conduit 15 is thermally coupled closely to the base plate 13.
  • the branches are also connected to each other at the latter end of the cooling element 3 and the lower line 15 may be connected at the first-mentioned end parallel to the upper line 14 with the cold water supply or the cold water return.
  • the branches of the upper conduit 14 and the lower conduit 15 are covered by insulating strips 16, which thermally isolate them against the take-off area 11.
  • the insulating strips 16 may consist of a suitable thermally insulating material, for example of a foam such as polystyrene or glass wool or rock wool.
  • damping strips 17 attached, which consist of a sound-absorbing material such as rock wool or glass wool. However, they leave one of several parallel, each over the entire length of the cooling element 3 extending strip existing withdrawal surface 18 free, where the trigger region 11 extends to the top of the base plate 13.
  • a Stretch ceiling 19 arranged, which extends horizontally over the entire surface of the room 2 so that it forms a the underside of the ceiling 1 and the cooling elements 3 and the spaces 4 completely concealing and separating from the room 2 dividing ceiling. It consists of an air-permeable flexible material.
  • a perforated film of non-flammable or at least flame-retardant plastic such as e.g. Polyester with polyurethane coating or PVC.
  • the perforation consists of even round holes distributed in a uniform grid over the surface of the stretch ceiling 19 with a diameter of e.g. between 0.5mm and 1.0mm.
  • the free cross-section is not more than 12%.
  • the perforation of the stretch ceiling can vary over a wide range and should be so matched to the cooling air temperatures that no unwanted cold air flows occur. At cooling air temperatures, in general, the hole sizes and the free cross-section must be chosen smaller.
  • the material of the stretch ceiling 19 may also be an air-permeable fabric. It may be made of polyester and has a mesh size of e.g. have about 0.5mm.
  • the open area is preferably not more than 12%.
  • the properties of the fabric, such as mesh size and open area, should also be matched to the cooling air temperature.
  • cooling air at a temperature of, for example, 16 ° as a supply air in the supply air ducts 10a, b of each cooling element 3 is directed from the air supply. It exits through the outlet openings 12 into the adjacent intermediate spaces 4, where it flows along the underside of the pre-cooled room ceiling 1. It then falls off in each case against the middle of the gap 4 to the stretch ceiling 19, at the top it flows back against the cooling element 3. It warms up by contact with the stretch ceiling 19, which absorbs heat from the room 2, especially by radiation exchange, something on. Partly it flows through the openings in the same down into the room 2, on the other part it rises again to the ceiling 1. So it forms, as in Fig. 1 indicated, driven by the exiting cooling air convection roller that transports heat from the stretch ceiling 19 to the ceiling 1. The air circulating in the intermediate space 4 thus cools the stretch ceiling 19 and heats up on the same before it exits into the space 2.
  • the surface of the stretch ceiling 19 mainly by radiation exchange essentially completely cooperates with the room cooling and on the other hand, the risk that the entering into the room 2 cooling air disturbing cold air flows caused decreases.
  • the space 2 is opposite a slight overpressure, but should not exceed about 5Pa, so that the stretch ceiling 19 does not bend down visibly.
  • the cooling effect of the cooling air can be assisted by passing cooling liquid through the lower line 15.
  • the base plate 13 and the adjoining region of the stretch ceiling 19 are cooled more strongly and thus the cooling of the space 2 by radiation exchange with the lying below the cooling elements 3 parts of the stretch ceiling 19.
  • the lower line 15 is in series with the upper line 14, preferably a high flow rate is selected, so that in the latter at most a slight heating of the cooling liquid occurs and the lower line 15 is still cold and a strong cooling effect is achieved.
  • the room 2 If the room 2, however, to be heated, it can - in addition to any supply of hot air as supply air - the lower line 15 are also switched between a hot water supply and a warm water return, preferably so that only or at least the lower first Line 15 is flowed through.
  • the flow rate should be small so that the heating effect concentrates on the space 2.
  • the intermediate time is used to pre-cool the ceiling 1, so that a high cooling performance can be achieved during the operating times with moderate, substantially matched to the fresh air demand.
  • coolant is passed through the upper conduit 14. Because of the narrow thermal coupling, the ceiling 6 is thereby strongly cooled. Radiation exchange and, to a lesser extent, convection, between the top surface 7 and the bottom of the ceiling 1 then lead to the desired cooling of the latter. If the lower line 15 is in series with the upper line 14, then it is advisable to choose a low flow rate, so that the cooling effect occurs especially in the latter and a supercooling of the space 2 is avoided. The extraction of air is omitted during the meantime.
  • the stretch ceiling 19 is therefore not drawn to the cooling elements 3, but runs without touching just below the same, so that it is thermally coupled to them weaker and less cooled.
  • the stretch ceiling 19 is thermally less strongly coupled to the ceiling 1 than during the operating time. Since it also largely prevents direct radiation exchange of the ceiling 1 with the room, the Room cover 1 can be cooled much more strongly in the meantime than would otherwise be the case Thus, in the subsequent operating time a much higher overall cooling performance can be achieved, so that very large heat loads in the room 2 can be compensated.
  • the air outlet may also be directed obliquely upward or substantially to the side against the adjacent gap.
  • the stretch ceiling can also be arranged at a distance below the cooling elements rope. The removal of exhaust air is then not via the cooling elements, but via other facilities. The supplied cooling air is distributed over the entire surface of the stretch ceiling distributed in the room, while otherwise does not change the essential function of the air conditioning ceiling.
  • the stretch ceiling can also be and for this purpose a dividing cover of between the perforated intermediate plates, preferably arranged on a common height of the base plates thereof, e.g. made of aluminum, which only separates the spaces between them from the space below.
  • the addition of exhaust air can be done by the cooling elements or by separate facilities.
  • the cooling lines may also be missing. In this case, the cooling of the ceiling in the meantime by supplying cooling air takes place.
  • the ceiling in this case may not be so much pre-cooled because of the convective coupling to the divider, but more effective the effect of the divider as between the ceiling and the room Radiation shielding are the relevant opportunities for even better.
