Definitions

  • the invention relates to an arrangement for achieving a predetermined humidity range within an enclosure in terms of a limited space area and thus as a result avoiding peak values of the room humidity, both in the minimum range and also in the maximum range.
  • the enclosure may be the space of a building, the enclosure of a culturally valuable object to be preserved, a container for the transport of sensitive goods and the like.
  • the invention is applicable in the environment of such substances or technical processes in which significant fluctuations in the room humidity lead to problems, as is the case for example in the art in the processing of filaments.
  • OE 90 03407 Ul is proposed to use a cladding panel of porous plastic, on the view side, a skirt layer is applied, which is prepared with a salt coating.
  • the cladding panel therefore acts like a sponge and is suitable for binding room humidity, in particular in damp rooms, and dissipating it with appropriate laying. Disclosure of Invention Technical Problem
  • the object of the invention is to propose an arrangement by means of which the properties of standing in contact with the indoor air near-surface boundary surfaces of bodies and other avengers in a room are changed so that they affect the surrounding humidity by surrounding at lesser ambient Humidity moisture is released or absorbed at higher ambient humidity.
  • the object is achieved by in a sufficient pore volume on free surfaces that contact the room air, a targeted increase in the hygroscopic behavior for stabilizing and regulating the room humidities has been brought about by harmless in this pore volume substances with hygroscopic effect in physical ways have been attached. This is always possible when a certain ratio of pore volume has been added to the extent of crystal growth or has been achieved by additives, so that resulting crystallization, hydration or swelling processes remain free of damage.
  • This pore volume is either present objectively in the material matrix or must additionally be produced in the near-surface region of these free surfaces by pore formers or be provided by additives, for example highly microporous calcium silicate.
  • the substances with hygroscopic action are salts or the like.
  • salts it is possible to use those which have a high degree of safety with regard to non-excludable damage to the environment. This applies, for example, to table salt, magnesium nitrate, potassium carbonate and calcium chloride.
  • the room humidity is buffered by absorbing this room humidity in the event of an oversupply and releasing it again with a time delay, thus creating a balance between the maximum and minimum values of the air humidity within the respective space.
  • these hygroscopic substances are deposited in the near-surface areas of walls, ceilings, floors and furnishings. This is done by means of suitable specific technologies, for example in curtains or papers that have a pore volume, by soaking them in a salt solution and then drying them. For ceilings, walls, foils and similar surfaces such as wallpaper special paints or emulsions are possible. If no sufficient pore volume is present, powdery, highly microporous bulk materials must be mixed with the paints. This can be, for example, treated organic additives or powdery highly porous substances how the abrasion with a highly microporous structure is in the sense of creating increasing storage capacity.
  • the surfaces contacting the room may be furniture surfaces or avenues of other furnishings, but also masonry surfaces, applied plasters or even wallpaper and paintings. It has been found that when these hygroscopic substances accumulate in a sufficiently created or existing pore volume in the support materials, for example wallpaper, destruction of the surface or the structure or the color does not occur.
  • the inventive design of the arrangement may thus also have features that represent a combination of the respective individual features of the claims.
  • Charging the microporous layers with the room air humidity is basically to be coupled with a possibility of discharge if a subsequent charging process is relevant.
  • the layers discharge themselves in load-free periods on the free surfaces under natural conditions in the presence of a directed into the room humidity gradient with an existing basic ventilation by itself.
  • Lighting equipment and heating surfaces and similar acting technology can be used with appropriate design for storage.
  • a discharge of stored moisture takes place, by functionally having a "heating surface” which has an effect during a "heating time”.
  • a passive regulation of the room humidity takes place as an essential Component of the room climate.
  • the method is not only user-friendly, but also user-independent effective. Noise or other annoyances are not present, and additional space is hardly required. Likewise, the supply of energy for process control is eliminated.
  • the regulation of the room humidity can be intensified by a device for intensifying the air movement in the room has been assigned in connection with the inventive design of the surfaces contacting the room air.
  • the intensification can be influenced by changing the temperature by means of ancillary equipment, which may be heating or cooling.
  • An expedient arrangement of a heating device may be formed in a building in such a way that a surface heating is embedded in a plaster layer, so that a gradient is present in the plaster layer.
  • heating and cooling device and a device for intensifying the air movement is possible.
  • FIG. 1 shows the course of sorption isotherms with different amounts of hydroscopically active substance of treated carrier materials
  • FIG. 2 shows the course of the moisture absorption following a process according to FIG.
  • FIG. 3 shows the course of the change of relative air humidity and of the deposited moisture mass, based on the following exemplary embodiment. The best way to exploit the invention
  • a paint is prepared according to the mass ratios of 2000 g to 1320 g to 330 g to 220 g by intensive mixing. This painting is sufficient for one square meter of a defined structure. This is coated on one side so that the intensively mixed paint is homogeneously distributed.
  • this building After drying, this building is brought into a room and exposed to a relative humidity of 80%. In permanence its mass and the surrounding humidity are measured and written down. After 12 hours, the humidity is lowered to 50%. This will continue to be operated alternately. The measurements continue to be made on a permanent basis and are always adequately written down.

Abstract

L'invention concerne un arrangement pour atteindre une plage d'humidité de l'air prédéfinie pouvant être choisie à l'intérieur d'une enveloppe à savoir d'une zone d'une pièce délimitée et par conséquent pour éviter des valeurs de crête de l'humidité de la pièce. L'objet de l'invention est de proposer un arrangement à l'aide duquel les propriétés des surfaces de délimitation des corps et des autres surfaces présents dans la pièce proches des surfaces en contact avec l'air de la pièce sont modifiées de telle sorte qu'elles influencent l'humidité de l'air ambiant en ce que de l'humidité est délivrée en présence d'une humidité ambiante faible ou absorbée en présence d'une humidité élevée dans la pièce. Cet objet est réalisé en ce que, dans un volume poreux suffisant sur les surfaces libres qui sont en contact avec l'air de la pièce, une augmentation ciblée du comportement hygroscopique a été provoquée en vue de stabiliser et de réguler l'humidité de la pièce, en déposant physiquement et sans dommage dans ce volume poreux des substances ayant un effet hygroscopique.
