Definitions

  • the invention relates to an arrangement for dissipating heat loads from a room via cooling surfaces, in particular via a prefabricated ceiling, which is formed from essentially air-impermeable elements and held by a supporting structure, suspended from a bare ceiling, or a wall shell placed in front of a bare wall, between the bare ceiling and the suspended wall Finished ceiling or between the raw wall and the wall shell in front of the room, a cavity is formed in which at least one cooling device is provided with a heat exchanger that can be connected to a cold source via supply and return lines, with the finished ceiling or wall shell being reduced to lower the surface temperature forming elements air, which is passed through the heat exchanger and cooled to reduce its heat content, is introduced cooled as heat transfer medium into the cavity.
  • ceilings are composed of elements which are flowed through by a heated heat transfer medium for heating purposes, operated with a cold heat transfer medium, have a cooling effect as chilled ceilings and can dissipate excess thermal energy from a room; they act as a "flat heat sink” that absorbs heat from the room and can dissipate it via the cold heat transfer medium.
  • These known cooling ceilings derived from the ceiling elements developed for the ceiling heating are connected to a heat transfer circuit with a liquid heat transfer medium with flow and return, from which a part of its heat content is extracted in a refrigerator, which is fed into the flow with a reduced temperature, the part its heat content added while cooling the ceiling elements and warmed up again in order to emit this heat again in the refrigerator.
  • the ceiling elements contain a pipeline that can be connected to the flow and return of the heat transfer medium.
  • the pipes of the pipeline must have heat transport surfaces which ensure an at least approximately uniform surface temperature.
  • great care must be taken. This means that the ceiling elements cannot be designed so flexibly in themselves that not all the requirements of interior design can be met.
  • these ceilings are provided with air-impermeable ceiling elements, which are arranged in a sealed manner in the structure.
  • the elements in all known embodiments with supply and return lines are also connected to a heat transfer circuit, the liquid heat transfer medium of which part of their heat content is extracted in a refrigeration device, which is thereby removed reduced temperature is fed into the flow, which replenishes part of its heat content while cooling the ceiling elements and warms up again in order to emit this absorbed heat in the refrigerator again;
  • the ceiling elements must contain a pipeline that is to be connected to the flow and return of the heat transfer medium. With ceilings of this type, heat is extracted, which can reach up to 150 W / m 2, which generally leads to surface temperatures on the ceiling elements which, measured in terms of comfort, are too low.
  • Each of the cavities is supplied with cooled air via ventilation ducts.
  • the heat flow that can be removed is limited by the temperature difference, which is limited due to draft and comfort problems, and the supply air flow, which is restricted for the same reasons; in addition, such indirect cooling is only with one to achieve complex duct network, since the ventilation lines require a considerable amount of space due to the air flow required to dissipate larger amounts of heat and require complex installation.
  • Air is circulated as a heat transfer medium and cooled on the heat exchanger with each circulation.
  • a forced circulation of the cavity air is achieved with the cooling device provided with at least one fan, it being the same whether the fan is designed as an axial or radial fan, the latter advantageously being double-flow for better use of space.
  • the cooling device provided with at least one fan, it being the same whether the fan is designed as an axial or radial fan, the latter advantageously being double-flow for better use of space.
  • the fan blow-out is preferably followed by a blow-out muffler, preferably provided with baffles, which increases the sound insulation, so that here the sound-insulating effect of the heat exchanger downstream of the fan is improved.
  • the blow-out openings are advantageously arranged in pairs so that the air outlet directions are at an angle greater than 0 ° and at most 90 ° to a plane that is perpendicular to the suspended prefabricated ceiling and goes through the axis of the blow-out pipe, which means that the area that can be painted is Elements is defined, where a small angle means a narrow, a large angle a wide range.
  • the exhaust pipe is also aligned parallel to the raw ceiling, while the outflow openings are directed towards the wall shell on one side.
  • an air collecting pipe which is also aligned parallel to the raw ceiling, is advantageously connected to the intake of the cooling device, the collecting openings of which are directed towards the raw wall in order to achieve the desired air circulation.
  • a free convection of the cavity air is achieved with a cooling device, which is formed by a channel-shaped housing with a finned tube as a heat exchanger that can be connected to a cold source via supply and return lines, with at least one air outlet slot arranged in its lower area and with one in its upper area arranged air inlet slot, both extending in the direction of the longitudinal extent over the length of the cooling device, at a distance from one another in which the finned tube is arranged.
  • the cooling device is arranged in the cavity such that free convection of the cavity air cooled in it is achieved.
  • free convection of the cavity air is achieved solely by the difference in density between heated and cooled air; this makes this embodiment particularly easy to install.
  • the cooling device arranged in the cavity between the raw ceiling or raw wall and suspended ceiling or wall shell is preferably fastened to the raw ceiling and thus fastened to a component which is not subject to further changes and to which, as a massive component, the cooling device in a manner known per se by means of vibrating elements can be attached to the bare ceiling with vibration damping. This prevents vibrations from being transmitted into the raw ceiling or the raw wall. If the heat exchanger is further designed as a dehumidifier and provided with means for collecting and discharging condensation water, it is possible to effectively dehumidify the cavity air and thus prevent the accumulation of condensation water on the inside of the cooled elements of the ceiling or wall shell construction.
  • the cooling device is advantageously provided for cooling a prefabricated ceiling parallel to the suspended ceiling and at a distance therefrom in the cavity formed between the suspended prefabricated ceiling and the bare ceiling, the air outlet slots being provided on the lower area on both sides of the duct-like housing for the outflow of cooled cavity air are and the air inlet slot for the backflow of the cavity air reheated on the elements of the suspended ceiling is preferably provided in the center, and the lower part of the channel-like housing is designed as a collecting trough for condensed water.
  • the air outlet slots are advantageously arranged in pairs such that a symmetrical outflow of the cooled air is achieved.
  • a vertically directed apron is suspended under the channel-like housing of the cooling device, which ends above the floor and forms a gap of approximately half the width of the cavity, the apron preferably being arranged in the middle of the cavity .
  • the cooling device is advantageous is attached to the bare ceiling with an angle profile which extends at least over half the length, preferably over the entire length of the cooling device.
  • the elements forming the suspended ceiling or the front wall shell are designed as metallic elements, which preferably have cooling pockets to improve the heat transfer with additional heat-conducting surfaces. If the sides of the elements forming the suspended ceiling or the facing wall shell that face the cavity further have fins or tubes that enlarge the heat exchanger surface, the heat transfer is also favored; The fins or tubes are advantageously aligned approximately parallel to the direction of the convection flow.
  • a further improvement in the heat transfer of the elements for the suspended prefabricated ceiling or the wall shell in front is achieved if it is provided with tubular cooling pockets, the outer walls of which are heat-conducting, and into which an inner tube open on both sides is inserted. These cow pockets allow an air flow in which the air is led through the inner tube into the depth of the cooler pocket and is cooled on the outer tube in order to exit the cooler pocket when cooled.
  • fins or tubes with the heat-transfer-enhancing heat-conducting surfaces are formed as hollow bodies, which in the manner of "heat pipes” form heat-conducting elements filled with an evaporable heat transfer fluid, heat transfer is achieved which is greater than metallic heat conduction, the Surfaces of these "heat pipes” enlarge the surface available for heat exchange and thus also the controllable heat flow.
  • FIG. 1 shows a sectional view of an air-conditioned building with a central air-conditioning system 2, and the horizontal and vertical air distribution channels 2.1 and 2.2 for the supply and exhaust air, which supply the storeys.
  • the air conditioning system 2 presses the conditioned supply air via the air distribution duct 2.1 into the air-conditioned rooms of the building and sucks the return air back to the air conditioning system 2 via the second air distribution duct 2.2; Part of the return air is discharged to the outside as exhaust air, the other part is mixed as recirculated air into the drawn-in outside air and then fed back into the rooms with this after thermal and possibly hygienic treatment as supply air.

  • the low-pulse feed of air into the ceiling cavity has the advantage that flow noises are only generated at a low level from the outset. It goes without saying that supplying the ceiling cavity via beam passages also leads to the desired result.
  • the jet outlets of adjacent cooling devices 10 can be directed such that the air jets emerging near the raw ceiling 1.1 meet in opposite directions and are directed against the finished ceiling 6 in order to flow back along this to the cooling device 10. Since the raw ceiling 1.1 is also cooled, and since the heat inflow through the raw ceiling 1.1 can be neglected in equilibrium with respect to the heat inflow through the prefabricated ceiling 6 forming the cooling ceiling, this is preferable if the geometry of the ceiling cavity 3 requires jet ventilation for air circulation.
