Definitions

  • the invention relates to a chilled ceiling for cooling rooms in buildings.
  • water-cooled cooling ceilings For the dissipation of heat from rooms, water-cooled cooling ceilings are known, in which cooling pipes are arranged above a ceiling plate, through which cooling water flows. The cooling pipes cool the ceiling panel, which in turn transfers the cooling to the space below.
  • a major disadvantage of water-cooled cooling ceilings is the risk of condensation forming on the cooling water pipes and distribution pipes. Since the room air comes into contact with the cooling water pipes, condensate from the room air is knocked off on the cooling water pipes if they are too cold. Normally, cooling water temperatures lower than approx. 17 ° C cannot be used. Condensation The pipes can only be prevented with a complex control that increases the cooling water temperature if there is a risk of condensation. However, this also reduces the cooling effect.
  • condensation water is increasingly formed on the cooling pipes. This condensation drips down and runs along the cooling pipes. There are rotting and rotting nests.
  • the supply lines to the cooling pipes are usually provided with vapor-tight thermal insulation in order to avoid condensation.
  • the invention has for its object to provide a room chilled ceiling in which the problem of condensation does not occur and which causes a pleasant and effective room cooling.
  • the room chilled ceiling according to the invention is an air-water chilled ceiling, the water (or another cooling liquid) flowing through the cooling tubes and, at the same time, dried supply air into a connecting one of these cooling tubes Pressure chamber is initiated. flows.
  • the dried supply air has a relatively low dew point, which is in any case below the temperature of the coolant. Since water from the air only condenses when the temperature of the cooling pipes is lower than the dew point of the air, no condensation forms on the cooling pipes. This dew point is set, for example, by cooling the supply air in a central air conditioning unit to a value which is below the coldest possible cooling tube temperature. The air then releases its moisture in the drying device.
  • a major advantage of the room chilled ceiling according to the invention is that the supply air can be used for ventilation purposes.
  • a pleasant distribution of cold occurs because on the one hand the cooling ceiling transmits cooling power by radiation and on the other hand cool fresh air is also introduced into the room.
  • the supply air supply can be reduced to the level required for ventilation purposes.
  • the pressure chamber contains an overpressure compared to the room to be cooled and only dried supply air is supplied to the pressure chamber, no moist room air can get into the pressure chamber, so that moisture contained in the outside air cannot condense on the cooling pipes.
  • the air flow occurs exclusively from the pressure chamber into the room to be cooled and not in the opposite direction.
  • the cooling capacity can be increased in that the cooling liquid can be supplied to the cooling pipes at a relatively low temperature without the risk of condensation, because the dried air coming into contact only with the cooling pipes cannot form condensation water there. If the dew point of the supply air is 12 ° C, the lowest cooling water temperature can be 13 ° C, for example. With the exclusively water-cooled cooling ceilings, cooling water temperatures below 16 ° C are not possible due to the risk of condensation. As a result of low cooling water temperatures, the cooling surface can be reduced in the room cooling ceiling according to the invention in comparison with known room cooling ceilings with the same cooling capacity.
  • the invention consists in the combination of a water-cooled room cooling ceiling with air cooling.
  • the cooling capacities of water and air add up, with the additional advantage of avoiding condensation.
  • the suspended room cooling ceiling 12 is located under the concrete ceiling 10.
  • the room cooling ceiling 12 has a thin, good heat-conducting ceiling plate 13 on its underside and an airtight top wall 14 on its top.
  • the pressure space 15 located directly above the ceiling plate 13 is delimited at the top by a wall 16.
  • cooling pipes 18 are laid, which are filled with cooling liquid, e.g. Cooling water, are flowed through.
  • the cooling liquid is supplied to the cooling pipes 18 via distributor pipes 19 in order to then be returned in the manner of a circulation system.
  • the cooling tubes 18 lie in heat-conducting contact on the ceiling plate 13.
  • Dried supply air is supplied to the pressure chamber 15 through a supply air duct 20.
  • the supply air duct 20 is connected to an air drying device (not shown), for example an air conditioning central unit, which cools the air down to the intended dew point, the air releasing liquid. If the air is then heated, it maintains the dew point assumed in the cooling device as long as it does not absorb any new moisture.
  • an air drying device for example an air conditioning central unit, which cools the air down to the intended dew point, the air releasing liquid. If the air is then heated, it maintains the dew point assumed in the cooling device as long as it does not absorb any new moisture.
  • the air thus dried passes through the supply air duct 20 into the pressure chamber 15 and leaves it through numerous holes in the ceiling plate 13 designed as a perforated plate.
  • the air flows along the cooling tubes 18.
  • the temperature of the coolant in the cooling tubes 18 is higher than the dew point of the supply air, so that no moisture condenses in the pressure chamber.
  • a volume flow of approx. 4-15 m3 / h m2 is recommended as the supply air volume flow, in accordance with the hygienic requirements.
  • the cooling pipes lie closely on the ceiling plate 13, but their round shape allows extensive rinsing with dry supply air. So that a slight overpressure is maintained in the pressure chamber 15 compared to the room to be cooled, the openings through which the cooling air leaves the pressure chamber 15 are throttle openings which offer a certain flow resistance.
  • a 0.5 mm thick fleece 21 is attached under the ceiling plate 13, which increases the flow resistance and evenly distributes the air flow over the surface.
  • the fleece can also be arranged in the pressure chamber above the ceiling plate.
  • the ceiling plate 13 thereby forms an air outlet for room ventilation.
  • the distributor pipes 19 are also arranged in the pressure chamber 15, thermal insulation of these pipes is not necessary. Because they are in dried air, there is no risk of condensation on these pipes.
  • the supply air is fed into the pressure chamber 15 at a constant temperature and constant volume, while the cooling capacity is regulated by varying the cold water cooling capacity.
  • the supply air temperature is selected so that the supply air flow required to maintain the overpressure does not subcool the room can lead when the cooling water is switched off.
  • the cooling capacity is increased by switching on the cold water flow if the heat sources in the room require it.
  • FIG. 2 differs from that of FIG. 1 only in that the ceiling plate 13a is impermeable to air and in that there are 10 air outlets 20 in the vicinity of the room walls, through which the cold air leaving the pressure chamber 15 is throttled into the room 23 exits.
  • the distributor pipes 19 for supplying and removing the cooling liquid run inside the supply air duct 20, so that they are also protected there against condensation deposits.
