Definitions

the present invention finds its application in the field of buildings and in particular it relates with a wall dehumidification system. for reclaiming moisture from the masonry walls of buildings and adapted to be generally applied to any structure to be sanitized.
Wall rising damp is a widespread phenomenon not only in old or ancient buildings but also in modern ones not having good insulation from the ground.
the phenomenon of rising damp is due primarily to the nature of the materials used for the masonry, generally blocks of bricks, stones, pebbles of various sizes bounded together by mixtures of absorbent materials such as sand and concrete, provided with an intrinsic microporosity which allows water to rise for effect of capillarity.
the rising damp is also promoted by an electrolytic process onset in humid and salty environments, whose anode is formed at the level of the environment rich in water and whose cathode can be located in the high parts of the building.
Dehumidification techniques using emission of electromagnetic waves are also known, for example using microwave or other frequencies selected in a more or less arbitrary way, which carry out simultaneously the desalination of masonry walls by acting directly on the ions or the salts dissolved in water.
dehumidification techniques use the emission of an electromagnetic field of predetermined frequency in order to counteract the effect of capillary action of the water and promote the return toward an electrode placed down.
EP2157491 describes a further apparatus for dehumidification of walls operating by sending electromagnetic waves having predetermined frequency.
AT392109 and WO2006016011 disclose masonry dehumidification systems that use electromagnetic fields with variable frequency to match the characteristics of the field to the structure to be treated.
the object of the present invention is to overcome the above mentioned drawbacks, by providing a dehumidification system of walls that is particularly effective and economical.
a particular object is to provide a dehumidification system of walls acting on the moisture present in the masonry structure in a non invasive way.
Still another object is to provide a dehumidification system of walls that is effective against any wall structure, regardless by its specific chemical/physical composition.
a wall dehumidifying system which, according to the invention, as defined by claim 1, comprises a generator of a magnetic or electromagnetic field adapted to generate and direct a magnetic or electromagnetic field on a wall structure to be dehumidified, means for voltage powering of said generator, an electronic control unit for said generator having a driving circuit supplied to said powering means and adapted to send a driving frequency signal to said generator for generating said field.
the control unit comprises pulse-type adjusting means adapted to control said driving circuit for generating a driving signal of the pulse type for the generation of an impulsive electromagnetic field variable in frequency.
the driving circuit sends an impulsive driving signal to the power stage of the generator with a frequency adjustable within a predetermined range.
said driving signal may be adjusted within a range between 10Hz and 10kHz.
the system will be able to perform a scan of the wall structure to be dehumidified at various frequencies in order to adapt the field to the specific chemical/physical composition thereof or possibly to prescind of such a composition as the field issued within an entire working cycle will be set from time to time in an optimized manner with respect to different compositions of the wall structure.
the adjusting means comprise a programmable clock generator adapted to generate a sequence of pulse signals having fixed width and different frequencies within said range and a programmable timer adapted to define the duty cycle of each of said pulse signals, in such a manner to preset a multiplicity of different sequences, increasing the flexibility of use of the system.
the adjusting means may comprise a first adjustable power feeder adapted to power said driving circuit with a variable voltage between 5V and 12V for varying the power of said field.
a system for dehumidifying walls is illustrated, which system may be used in restructuring, recovery or sanitization operations of buildings with any destination of use having one or more walls or other structures suffering from moisture.
the system may be used on any type of structure, such as walls, columns, pillars and other load-bearing elements of buildings, regardless of shape, size, materials.
the system comprises a generator 2 of a magnetic or electromagnetic field E essentially consiting of a power stage 3 , for example FET amplifiers, connected to a antenna 4 for emitting and targeting the field E toward the wall structure to be dehumidified.
a generator 2 of a magnetic or electromagnetic field E essentially consiting of a power stage 3 , for example FET amplifiers, connected to a antenna 4 for emitting and targeting the field E toward the wall structure to be dehumidified.
the generator 2 is connected to an external voltage source, generally the net power supply to 230VAC R , through voltage powering means 5.
the system 1 also comprises an electronic control unit 6 of the generator 2 provided with a programmable logic with one or more control boards supplied by the same powering means 5 and provided with a driving circuit 7 adapted to send a frequency driving signal S to the generator 2 for the generation of the field E .
the control unit 6 also comprises adjusitng means 8 of the impulsive type adapted to control the driving circuit 7 to generate a driving signal S of the pulsed type and generate a magnetic or electromagnetic field E also impulsive and variable in frequency.
the driving circuit 7 will be provided with a timing circuit of the signal of ON/OFF type applied to the power stage 3 for the generation of the pulse signal S .
the driving circuit 7 will be associated with a clock generator 9 having in sequence a series of dividers adatped to provide the driving signal S at various frequencies of adjustable value within a predetermined range, preferably between 10Hz and 10kHz.
the clock generator 9 will be programmable and adapted to generate a sequence of pulse signals S having a fixed width at different frequencies within the above range.
the adjusting means 8 will also comprise a programmable timer 10 adapted to define the duty cycle of each of the pulse signals S of the predetermined sequence.
the timer 10 may be programmable within a time range between 1min and 10min.
the control unit 6 will also comprise an internal hour-counter 11 , for example of the digital type, for storing the operation times of the system in order to control the periods of work.
the powering means 5 comprise a first adjustable power feeder 12 for supplying the driver circuit 7 with a variable voltage between 5V and 12V to vary the power of the field E .
the first power feeder 12 may be associated with a second stabilized power feeder 13 that connect to the general network, possibly with the interposition of a third power feeder 14 to bring the voltage from 230VAC to 12VDC.
the second stabilized power feeder 13 also connects the central control unit 6 with the mains supply R to power its logic with a predetermined and constant voltage, generally with a stabilized value of 5VDC.
the structure of the generator 2 may vary too, depending on the needs and according to methods known to the skilled person.
