Definitions

  • the invention relates to a method for air conditioning work, living or common rooms, in particular in residential or office buildings, schools, hotels, congress and / or exhibition halls, theaters, cinemas, hospitals, laboratories, warehouses, and / or breeding rooms, gyms, swimming pools or the like and, according to a second overarching inventive idea, relates to a device for air conditioning work, living or recreation rooms in buildings of the type described above, which is particularly suitable for carrying out the method according to the first overarching inventive idea.
  • air conditioning systems which are individually assigned to each room are conventionally used, which suck in fresh air from the outside environment and condition it, i.e. bring to a certain temperature and / or relative humidity and then deliver a more or less closable outlet grille into the room to be air-conditioned, usually with a controllable closure element, such as a folding blind or the like.
  • the sheet metal parts required for the air ducts not only require professional fastening or anchoring to the wall or ceiling of the room to be air-conditioned, but in some areas are not available at all or are only available at practically unaffordable prices In terms of their climatic conditions, the buildings there urgently need at least air cooling, if not conditioning, in the sense of additional humidification or dehumidification.
  • underfloor heating is known to be particularly suitable when these are to be heated, since this ensures that the heat is supplied from below and rises to the top with a low energy input and is therefore available there to a sufficient extent stands where it is used as far as possible or is felt to be particularly beneficial.
  • underfloor heating systems are practically impossible to achieve with the known types of room air conditioning, since on the one hand the outflow grilles represent scraper and scraper and thus ver very quickly would be uncleaned and the dirt would be whirled up by the relatively high outflow speed of the supplied air and carried into the room as dust in an extremely harmful manner, but on the other hand the draft coming from below would also lead to nuisance and the risk of health damage if it were clean.
  • this feeling of comfort which is expressive as a sensation especially in humans, but also in machines, such as computers, is expressed in increased functional reliability with reduced sensitivity to faults and significantly longer maintenance intervals, and not just from the temperature and possibly moisture distribution depends on a certain representative cross-section of the room to be air-conditioned, but also essentially on the temperature distribution over a certain boundary surface of this room, such as a wall thereof, on which the local distribution of the relative humidity of the zones in question in the neighboring room atmosphere can also depend. This is not satisfactory, although no solution to eliminate this inconvenience is yet available.
