Definitions
- the present invention relates to a procedure and an apparatus for removing moisture and/or mould from a structure in a building.
- 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.
- microwave radiation is detrimental 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 possible 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 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, wherein the air flow uniformely flushes the surface of the structure to be dried over the whole area under the infrared radiator, 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 radiation 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. Infrared 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 apparatus 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 infrared 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 environment 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.
- Styrox thermal insulation of cellular plastic
- the wavelength of the infrared radiation emitted by the infrared radiator is in the near-infrared range.
- the wavelength of the infrared radiation emitted by the infrared radiator is longer than or equal to 900 nm, preferably about 900 - 3000 nm.
- 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.
- 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.
- the means for creating a negative and/or positive pressure comprise an air duct opening to the inside of the casing and a fan disposed in the air duct to create suction and/or blowing.
- the apparatus comprises a first humidity sensor disposed inside the casing near the structure to be dried for the determination of humidity in the vicinity of the structure and for supplying the controller with a signal corresponding to the humidity.
- the apparatus comprises a second humidity sensor, which is disposed in the air duct for determining the humidity of the air flowing in it and for supplying the controller with a signal corresponding to the humidity.
- the apparatus comprises a first temperature sensor, which is disposed inside the casing in the vicinity of the structure to be dried for determining the temperature near the structure and supplying the controller with a signal corresponding to that temperature.
- the apparatus comprises a second temperature sensor, which is disposed in the air duct for determining the temperature of the drying air flowing in it and supplying the controller with a signal corresponding to that temperature.
- a drying system that could be used e.g. in conjunction with the reparation of major water damage.
- the system can be implemented e.g. by connecting a necessary number of drying apparatus as provided by the invention to a common central control unit, which may be a computer or equivalent.
- a computer in the system could collect humidity, temperature and flow data from the control means of each apparatus, analyse the data and control the temperature and flow rate in each apparatus individually, taking the overall situation regarding drying of the object into account.
- the system may comprise an output device connected to the computer to allow the printing of reports relating to the drying, temperatures and humidity in different parts of the object, etc.
- an output device connected to the computer to allow the printing of reports relating to the drying, temperatures and humidity in different parts of the object, etc.

- the open side of the casing box 1 is placed against the structure to be dried.
- Mounted in the hollow space inside the casing 1 is an infrared heater panel 2, which emits heating radiation to the structure to be dried.
- the apparatus is provided with means 3, 4 for creating a negative and/or positive pressure inside the casing 1 to produce an air flow inside the casing.

- a 70 mm thick wet concrete slab as shown in Fig. 1 can be dried in 3 - 7 days.
- the structure is subjected to periodic infrared radiation from an IR radiation heater 2 by first heating the structure continuously for a given period so that it reaches a temperature of 60 - 75°C.
- the surface of the structure is cooled by a continuous or periodic weak suction air flow, which is produced by means of the fan 4, whose suction side is connected to the air duct.
- the heating is interrupted for a substantially long period of time while suction is carried on to draw air from inside the casing, i.e.
- a negative pressure is maintained throughout this cooling phase.
- the temperature of the cooled surface of the structure becomes somewhat lower, e.g. about 3 - 8 °C lower than the temperature inside the structure raised by heating. Therefore, the moisture in the warm structure tends to drift towards the cooler surface, from where it effectively evaporates into the suction air due to the slight negative pressure.
- the structure After the structure has been dried, its temperature can be raised for a short period of time to 100 - 110 °C to eliminate mould and spores from the surface of the structure and from the structure itself.

- the resistance wire pattern 16 has been adapted to the hole 11.
- the length of resistance wire on the panel is about 100 metres.
- the IR radiator has been fitted to emit infrared radiation at a given wavelength. In a preferred case, infrared radiation in the near-infrared range is used, which has a good ability to penetrate into wet structures.
- the wavelength may be e.g. about 1000 nm.
- the moisture is mainly removed via that surface which is cooled by air flushing and from whose direction the heating is applied.
- the structure to be dried consists of a 70 mm thick concrete slab, with a 70 mm expanded polystyrene insulation under the slab and sand under the insulation.
