Definitions

  • the present invention relates to an air humidification device. Furthermore, the present invention relates to a method for humidification.
  • Air humidification devices are known in which a humidifier medium is arranged in an air stream and the air stream is humidified by water trickling down in the humidifier medium and / or by spraying the humidifier medium.
  • Such known humidification devices have proven themselves. In their application, however, creates a considerable proportion of water loss, which can not be supplied to the air flow, and which must be collected and removed by means of a water bath. Accordingly, a larger amount of fresh water for humidification must be supplied or there is a return of loss of water to provide the spray nozzles.
  • the water bath can cause hygienic problems. Due to the presence of a water bath, the air flow must be routed horizontally through the water bath through the humidifier medium, which limits the mounting options of the humidifier.
  • humidification devices which humidify an air flow directly through spray nozzles with water.
  • these need demineralized water, so that no dust goes into the air.
  • a humidifier medium is partially immersed in a water bath and there absorbs water which is conveyed by rotation of the humidifier in an air flow.
  • hygienic problems can arise through the water bath.
  • the air flow must also be guided horizontally across the water bath through the humidifier medium, which restricts the mounting options of the humidification device.
  • the present invention is therefore based on the object to provide an improved humidification device, which reduces or does not have the disadvantages mentioned.
  • an air humidification device comprising an air duct section and at least one hydrophilic or hydrophobic, air-permeable humidifier medium arranged in the air duct section substantially perpendicular or oblique to its longitudinal axis, which is wetted with water by means of a water distribution, the amount of water to be applied being regulated in such a manner, that only as much water as necessary for humidifying the humidifier medium is applied and that no water escapes from below the humidifying medium.
  • the object of the present invention is also achieved by a method for air humidification by means of such an inventive humidification device.
  • FIG. 4 a fourth preferred embodiment of the invention, which can be used if the return air is to be cooled and then flows through a non-hygrophilic heat exchanger, which transfers the cooling to the supply air (so-called adiabatic return air cooling).
  • FIG. 1 shows a first preferred embodiment of the invention, with an air humidifying device with air direction from bottom to top.
  • a heater (6) located, which preheats the air to a predetermined temperature.
  • a temperature sensor (8) is used, which measures the air temperature and transmits this information to a controller (not shown), which controls the heater (6).
  • the humidifier medium (2) is used in the embodiment in FIG. 1 flows through from bottom to top and the air flowing through it is moistened. At the same time the air is cooled by this moistening.
  • a water distribution (3) is used to distribute the required water on the humidifier medium (2).
  • the water supply (4) is hereby regulated according to the measured value of a return air sensor (9), which is located in the return air flow.
  • a humidity sensor (7) advantageously measures the supply air humidity, which is used to regulate the maximum water supply.
  • FIG. 2 shows a second preferred embodiment of the invention, with an air humidifier with air direction from top to bottom.
  • FIG. 2 is in the direction of air (5) also first a heater (6) located, which preheats the air to a predetermined temperature.
  • a temperature sensor (8) is again used, which measures the temperature and transmits this information to a controller (not shown), which then controls the heater (6).
  • the humidifier medium (2) is used in the embodiment in FIG. 2 flows through from top to bottom and the air flowing through it is moistened. At the same time the air is cooled by this moistening.
  • a water distribution (3) is used to distribute the required water on the humidifier medium (2).
  • the water supply (4) is also regulated here according to the measured value of a return air sensor (9), which is located in the return air flow.
  • a humidity sensor (7) advantageously measures the supply air humidity, which is used to regulate the maximum water supply.
  • FIG. 3 shows a third preferred embodiment of the invention, which can be used if the return air to be moistened and then flows through a hygrophilic heat exchanger, which transmits the moisture to the supply air.
  • a return air sensor 9 shown, which is used to regulate the water supply (4).
  • the heater (6) which also preheats the air, is controlled to a temperature which is measured by the temperature sensor (8).
  • the humidifier medium (2) is flowed through in this embodiment from top to bottom, thereby moisturizing the air. At the same time the air is cooled by this moistening.
  • the water distribution (3) also distributes the water on the humidifier medium (2) and the humidity sensor (7) is used to limit the maximum supply air humidity.
  • FIG. 4 shows a fourth preferred embodiment of the invention, which can be used if the return air to be cooled and then flows through a non-hygrophilic heat exchanger, which transfers the cooling to the supply air (so-called adiabatic return air cooling).
  • the humidifier medium (2) is flowed through in this embodiment from top to bottom and the air is humidified. At the same time the air is also cooled by the moistening.
  • the water distribution (3) again distributes the water on the humidifier medium (2) and the humidity sensor (7) is used to limit the water supply (4) and the maximum humidity.
  • the water distribution (3) may include a sputtering device or a sprinkler device.
  • the humidifier medium (2) may be circular-cylindrical or rectangular. It is also conceivable to use several instead of one humidifier media (2), which are advantageously arranged one after the other in the air duct section (1) in the air flow direction.
  • the heater (6) can be an electric or a hot water heater. By means of a built-in before or after the humidifier medium (2) air flow sensor can be prevented that the humidification happens without air flow.
  • a safety tub can be provided, which can catch the water in particular in case of malfunction of the humidifier.
  • this safety sump may have a water detection device which prevents further wetting in an emergency and / or triggers an alarm.
  • the safety trough can also be arranged in such a way that the air can flow through this safety trough.
