Definitions

  • the present invention relates to a procedure as defined in the preamble of claim 1. Moreover, the invention relates to an apparatus as defined in the preamble of claim 15.
  • a further problem especially in the case of thick objects is that, with prior-art methods, the surface of the structure is heated to a relatively high temperature while the portions deeper inside the structure remain damp. This is because moisture tends to drift towards colder parts, so the hot outer surface of the structure constitutes a barrier to the drying of its deeper portions.
  • Yet another prior-art method for drying a structure is to apply microwave radiation to the object to be dried.
  • microwave radiation is det- rimental to health.
  • a drier using microwave radiation e.g. in an apartment, even the apartment below must be evacuated and also the space being dried must be continuously watched to keep outsiders away.
  • the object of the present invention is to eliminate the drawbacks described above.
  • a specific object of the invention is to present a new type of procedure that allows faster drying of structures than is possible by earlier methods and which makes it pos- sible to effectively combine the use of a heating element and air cooling for the drying of structures after water damage and for the elimination of mould.
  • a further object of the invention is to present a new apparatus for fast and economical drying of damp structures.
  • the procedure of the invention is characterised by what is presented in claim 1.
  • the apparatus of the invention for implementing the procedure is characterised by what is presented in claim 15.
  • the structure is heated through its essential thickness to a raised temperature that is sufficient to remove moisture and possible mould, and the surface of the structure is cooled by continuous air flushing so that the surface temperature of the structure becomes lower than the inside temperature raised by heating, with the result that the moisture in the warm structure drifts towards the cooler surface and is removed from the surface by the air flushing.
  • a temperature gradient is created in the structure.
  • the moisture can evaporate from the surface and the mould and spores can be eliminated.
  • the duration of the first heating phase is of the order of a few hours and the duration of the subsequent cooling phase with no infrared radiation applied to the structure is substantially longer and may be even many times as long as the duration of the heating phase.
  • very short heating periods may be additionally used during the cooling phase.
  • the essential point in the invention is the use of infrared radia- tion penetrating deep into the structure and the maintenance of a sufficient inside temperature as well as a somewhat lower surface temperature. Moisture is always removed from inside the structure towards a surface at a lower temperature.
  • the cooler surface can be formed by applying air cooling to that surface of the structure towards which the moisture is to be removed.
  • the invention has the advantage that the procedure of the invention allows a significant reduction of the time consumed for the drying of structures. In- frared radiation penetrates deep into the structure to be dried, yet without heating the air near the surface because the radiation needs no medium, allowing simultaneous cooling of the surface by air flushing. Moisture can be removed to a desired direction.
  • a further advantage of the invention is that the structure is very effectively dried throughout its thickness. Moreover, the procedure of the invention is not detrimental to health and therefore does not involve any extra health risk to persons working with the appara- tus or to outsiders.
  • the structure is heated using infrared radiation with a wavelength in the near-infrared range.
  • the wavelength is preferably larger than or equal to 900 nm.
  • Such radiation has a particularly good ability to penetrate into concrete structures.
  • the infra- red radiation is interrupted periodically and the surface is cooled continuously or periodically.
  • the infrared radiation is preferably interrupted periodically so that the ratio of active radiation time to interrupted time is about 2:4.
  • the structure is heated to a temperature between 35 - 110°C, and the surface of the structure is cooled by an air flow so that the surface temperature is 3 - 8°C lower than the inside temperature.
  • the temperatures are so selected that the mould filaments and spores are destroyed. It is known that the growth of mould stops and most of the active filaments are destroyed when the temperature is 55 - 60°C. Spores can be destroyed at a temperature of 80 - 100 °C. The filaments of most decay fungi die at temperatures between 35 - 80°C.
  • the part of the structure to be dried is isolated from the en- vironment so that a negative pressure can be created around it and air is drawn by suction from that area to create a continuous air flow flushing the surface of the structure to remove moisture as well as possible mould.
  • a slight negative pressure continuously maintained creates a suction that effectively removes any moisture drifting to the surface as well as organic residue and spores.
  • the exhaust air is preferably passed out of the building via a filter into the atmosphere.
  • air is blown at the surface of the structure to cool it.
  • the cooling of the surface of the structure can be enhanced by subjecting the surface to a blast of cold atmospheric air.
  • the air thus blasted is dehumidified using special filters so that the relative humidity of the air is about 10 - 12 %.
  • the structure is heated using an infrared radiation heater.
  • the wavelength of the thermal radiation emitted by the infrared heater is appropriate for creating a heat that penetrates deep into the structure.
  • the heating, air suction and/or air blasting are activated and interrupted in accordance with a predetermined precept.
  • the temperature of the structure being dried, its humidity and/or other corresponding quantities essential to moisture and mould removal are monitored and, based on this monitoring, the heating and air blasting/suction are regulated. Moreover, the flow rate, temperature and humidity of the air being blown and/or sucked can be monitored. Based on measured quantities, reports can be printed out.
  • a report may contain essential information regarding the progress of moisture and mould removal, such as temperature of the structure, air humidity, air temperature, process duration and/or other quantities to be defined.
  • the heating element is a planar infrared radiator provided with a central through opening; and the apparatus comprises a controller arranged to control the operation of the heating element and the means for creating an air flow inside the casing in accordance with a predetermined precept.
  • the controller is e.g. a timer which switches electric power to the heating element on and off.
  • the central opening in the infrared radiator is of essential importance to uniform cooling of the surface of the structure. Without a central opening in the radiator, cooling air will not flow to the central part of the planar infrared radiator, so the structure in the central part will be overheated. For instance, when a concrete slab with a thermal insulation of cellular plastic (Styrox) under it is being dried, the heat will easily burn through the insulation in the central area of the IR radiator if the surface cooling of the concrete slab is not functioning in that area.

  • the controller has been arranged to interrupt the infrared radiation periodically and to control a fan so as to make it work continuously or periodically. In an embodiment of the apparatus, the controller has been arranged to interrupt the infrared radiation periodically so that the ratio of active radiation time to interrupted time is about 2:4.

Abstract

La présente invention concerne un procédé permettant d'enlever l'humidité et/ou la moisissure de la structure d'un bâtiment, par exemple d'un plancher, d'un mur ou d'un élément équivalent. La procédure de la présente invention consiste à faire circuler de l'air à proximité de la structure devant être séchée et/ou à chauffer ladite structure en lui appliquant des phases périodiques d'échauffement et de refroidissement. On chauffe la structure dans toute son épaisseur à l'aide d'un radiateur infrarouge (2) jusqu'à une température suffisante pour enlever l'humidité et/ou la moisissure éventuelle, et l'on refroidit la surface de la structure par un souffle d'air continu de manière que la température de surface de la structure devient inférieure à la température interne atteinte par échauffement, l'humidité présente dans la structure chaude ayant tendance à se déplacer vers la surface plus froide, dont elle est éliminée par le souffle d'air.
