Definitions

  • the present invention relates to a method for drying of buildings, in which in several iterations, first during a heating phase, an accessible building layer is heated by means of an oriented on this infrared radiator, and then draws moisture from deeper building layers during a resting phase.
  • a device is already known from DE 698 06 000 T3.
  • an infrared radiator is provided, which is mounted in a housing and is placed with this housing at a location to be dried of the floor. This floor area, as far as it lies below the infrared radiator, is then periodically irradiated, while the moisture-absorbing air located inside the housing and heated by the infrared radiation over time and removed from the building is removed by means of a suction device.
  • a drying of a material to be dried is best carried out so that first takes place a heating and associated expulsion of moisture for a certain time and then exposed for a rest period, the irradiation with heat. During the rest period, the temperature in the building can then equalize and likewise the moisture can be distributed evenly. Subsequently, the process is repeated, so that the then re-entrained moisture is again removed in the second step, until in the end more or less the complete moisture has been removed from the structure.
  • the above-mentioned document indicates the ratio of radiation time to interruption time of "approximately 2: 4".
  • the radiation time and the interruption time are chosen more or less arbitrarily, which possibly represents a suitable solution for the relevant building material on which the development of the invention was based.
  • the user will therefore first of all and then decide on the basis of his feeling for an adjustment of the radiation time and the interruption time.
  • irradiation becomes ineffective after expelling the moisture in the front, irradiated areas and otherwise retreating the moisture deeper into the building, it remains unclear whether, in this way due to the user's arbitrary adjustments, excessive exposure and thus too high power consumption and possibly also too long duration of use and thus associated with a certain ineffectiveness.
  • building drying essentially involves drying the more or less soaked parts of the building as quickly as possible and with as little energy as possible. In that regard, it makes sense to optimize existing procedures in order to achieve greater effectiveness.
  • infrared radiators which represent the closest prior art
  • dehumidifiers adsorption and fan heaters are also known, which regularly edit only the medium of the air to be dried and thus only indirectly reach the surface of the material concerned.
  • core moisture is not, or only to a small extent, eliminated, because there is a residue of residual moisture, which is unavoidable due to the insufficient energy expenditure on the drying wall.
  • the wall loses much of its proper function, namely protection against wind and weather.
  • a wet or at least partially wet wall insulates significantly worse than a dry wall.
  • drying after the damage usually after removal of wallpaper, wood paneling, plaster, etc. can be performed and the wall is thus in an ideal state before damage elimination.
  • drying is not carried out completely and the protective coverings are replaced, this will cause part of the still present core moisture can slowly tighten, especially in time-lagged ideal conditions such as dry and warm air in the interior, and thus leads to mold and damage to the protective panels from the inside.
  • the present invention has the object to provide a method for drying of buildings, which works much more efficient and thereby achieves better drying both in a shorter time and with less energy use. This object is achieved by a method for drying structures according to the features of claim 1. Further, useful embodiments of such a method can be taken from the subclaims.
  • an infrared radiator is aligned with an accessible structural layer and that it is first heated for a heating phase. During a rest period, moisture can then follow from deeper building layers.
  • the infrared radiator is equipped with a control unit, which in turn is data-connected to a database.
  • a control unit which in turn is data-connected to a database.
  • at least one heating time within which the infrared radiator is to irradiate the building layer and at least one rest period during which the building layer is not to be irradiated is specified in the database.
  • the moisture After heating the upper layer and switching off the heat source, the moisture can escape well on the side facing the infrared radiator.
  • the wall surface also cools down, because the further heat input is temporarily stopped and the evaporative cooling on the surface ensures a heat difference directed from the inside to the outside, which supports the retightening of the moisture.
  • the time required for the respective building material to heat an effective layer varies and is material-dependent. The ideal value of
  • Heat-up time provides the best possible drying times with the lowest possible energy input, thus creating the basis for the best re-drawing effects. It is also necessary to choose a suitable rest period. The determination of these times and, if necessary, also the intensity of the respective energy input is the subject of continuous research and experience from which the said database is fed.
  • the next step is to determine the proper rest period, in which the moisture from the material inside can follow. Due to the solid barriers, porosities and capillary effects, each type of material has different times, in which it allows the moisture from the interior to draw in the drier, accessible building layer to the outside.
  • the dry outer layer absorbs the moisture from the interior in a similar manner as a sponge, the water, the moisture and the temperature throughout the material are eager to spread evenly.
  • control unit of the infrared radiator now essentially takes over the heat-up time and the rest period stored there, and will irradiate an accessible building layer in compliance with these times.
  • the material-specific data set may additionally be assigned a nominal power consumption with which the infrared radiator is operated during the heating-up time. Accordingly, the control unit will specify a corresponding desired power consumption and limit the heating power as needed in the infrared radiator accordingly.
  • the surface temperature of the accessible building layer can be detected using a temperature sensor of the infrared radiator with some advantage, so that not only the radiated power is in the foreground, but rather that power, too arrives in the building. In this way, a predetermined temperature of the accessible building layer can be sought, so that in the control unit ultimately a scheme is established, which holds over time the desired temperature at the surface of the accessible building layer.
  • a desired temperature profile in the material-specific data set can be predetermined, which provides for an adaptation of the desired temperature over time .
  • the control unit will adapt to the target temperature profile in question over time and switch on and off the infrared radiator in such a way that the surface temperature of the accessible building layer follows the desired temperature profile.
  • a measurement of the temperature profile at the surface is performed permanently by means of a temperature sensor. Since the temperature at a fixed introduced power of the infrared radiator characteristically develops in different building materials, a conclusion about the material used can be drawn from such a temperature profile, so that due to such a sample irradiation, the selection of the material-specific data set automatically by the system, in particular through the control unit, can be done. Hereby an arbitrary selection of a material data set by a user is pre-empted so that incorrect operation can be avoided at this point.

  • the convection can be intensified, for example, by making the infrared radiator diagonally opposite the accessible building layer, so that an upper edge of the infrared radiator is closer to the accessible building layer than a lower edge.
  • a chimney effect will set, which accelerates the heated air upwards and thus quickly dissipates from the heated area.
  • the discharged air can be guided along an air guiding device, which additionally has a cooling device, so that the moisture from the air will at least partially condense on the cooled air guiding device.
  • FIG. 1 shows a graph of the drying process according to the present invention, wherein on the longitudinal axis the passing time, on the vertical axis the relative humidity 3, the moisture loss 4 of the wall and the over the infrared radiator striking the wall striking energy radiation 5 is plotted.
  • the energy radiation 5 swings quickly after switching on a value and keeps this about as long as the infrared radiator is turned on. In the heating phase 1, the energy radiation 5 increases linearly and will remain constant at zero in the subsequent rest phase 2.
  • a first heating phase 1 it can be established that, on the one hand, the moisture 4 contained in the wall initially drops sharply in order to remain approximately constant in a first resting phase 2. This is repeated again in the second heating phase. 1
  • the third heating phase an inversion point is reached and it turns out that from here the moisture escapes from the wall mainly in the resting phases 2, but remains constant in the heating phases 1. This is because after an initial heating of the wall to be dried, the superficially bound moisture has escaped and only the deeper-seated moisture still remains in the wall. This will move out of the wall after the surface drying especially in the resting phase 2, when the moisture is no longer evades the applied heat.
  • Wall and panel represent a characteristic whose course depends on the condition of the wall.
  • the end of the heating phase 1 and the duration of the resting phase 2 are each selected so that a predetermined, material-dependent ideal value of the relative humidity 3 is achieved with the least possible power in the shortest possible time.

Abstract

Comme on le sait, pour sécher efficacement des bâtiments à l'aide de radiateurs à rayons infrarouges, il est nécessaire d'alterner des périodes de chauffage avec des périodes de repos de façon à pouvoir effectuer, après une phase de séchage, un suivi de l'humidité qui a tendance à se propager uniformément. Cependant, actuellement, le réglage des périodes de chauffage et des périodes de repos ne peut être effectué qu'intuitivement. Le but de l'invention est d'éliminer ce problème et de rendre le processus de séchage plus efficace. Ce but est atteint par l'utilisation de connaissances expérimentales qui sont fournies dans une base de données ou qui peuvent être converties en temps par des mesures. Les périodes de chauffage et les périodes de repos sont lues en fonction du matériau, et les conditions de séchage optimales sont ainsi crées en fonction du matériau à sécher.
