Description

The application relates to a device for air conditioning, in particular of church organs.

From "mold fungi in the interior - a consideration of building fabric technical and interior hygienic-medical view against the background of the special interior climatic conditions in churches and religious buildings", Dr. med. med. Ulrich-Friedrich Schmelz, Malsfeld, it is known that mold in sacred buildings is a problem. The climatic conditions in church buildings are hereafter particularly disadvantageous because church buildings are often quite cool, with a user-side moisture entry and on-site moisture entries are possible. In addition, the temperatures in religious buildings are such that mold fungi can thrive particularly well. Lack of access to light and insufficient air circulation contribute further to make the interior climate factors beneficial for molds. As constructional effects building fabric corrosion in the sense of changing wood surfaces are called, in particular foxing, loosening of glue joints and in particular leaks in organs, as well as infestation of leather parts. Recurring, inexplicable leaks in organs, loosening gilding and key pads and glue joints in general are observed. Macroscopic aspects of mold on organs with pictures are shown. As a precautionary measure, this article recommends avoiding the formation of condensation on surfaces by keeping the air temperature to surface temperature difference as constant as possible by constant heating, with air temperature changes always being smooth and as slow as possible at 0.25 ° C / h. After services, bump and cross ventilation should be performed, but not too long especially in winter. In this case, the standard climate should be after DIN 1946 not be left. To combat the usual chemical compounds are proposed.

From Burkhard Goethe "Mold formation in pipe organs, formation, causes, effects and elimination", organ counseling of the Evangelical Church in Württemberg, Schwäbisch Hall, 2007, it is known that since the year 2000 news about mold growth in pipe organs had increased noticeably. In particular, typical infestation features in organs are dealt with in this instrument. The causes given are insufficient heat, insulation levels and so-called cold bridges on the outer shell of the room. In addition, a problem is excessively narrow-built organs. The reason for this is small or incorrect place specifications of the client or exaggerated wishes of individual church musicians for a particularly large organ. Other points are the insufficient or too rapid periodic overheating, the increased moisture production in the room, poor ventilation behavior and the presence of building moisture. Cold bridges would be in organs z. As water films on smooth, cool parts (wood and metal pipes, iron parts) and form a small climate in the instrument. It was the organ then encapsulated on a cold outer wall and hardly ventilated, such a microclimate would be particularly encouraged. In this context, it is mentioned that partial heating of church rooms at weekly intervals not only favors the formation of mold but also the pupation process stored larvae of wood pests, such. B. Anobium punctate significantly accelerated and promoted. In order to remove mold fungus decay, washing with isopropanol is recommended in particular, as well as venting already cleaned demountable parts outdoors. In particular, not only incorrect heating behavior but also missing or defective ventilation behavior is noted as one of the causes.

It is an object of the invention to provide a device for air conditioning, in particular for the air conditioning of organs with the formation of molds prevented or existing infestation can be reduced and eliminated.

The object is achieved with a device having the features of claim 1.

Advantageous developments are characterized in the subclaims.

In the known methods and recommendations for the elimination or prevention of mold in sacred spaces and organs is disadvantageous either to combat mold fungi with chemicals or provide appropriate ventilation. The treatment with chemicals does not solve the problem of mold fungus formation, while it has been shown that ventilating church spaces does not change the infestation of a church organ or is able to actually effectively improve the climate in an organ.

In the method according to the invention, the interior of the organ is ventilated. The ventilation of the organ interior takes place with a blower, in particular a quiet fan or fans, which at least circulate the air in the interior of the organ. If a blower is used, a fine-pored filter is attached to the intake manifold for the blower. In particular, a so-called H13-HEPA filter is mounted, which from the sucked air, dust and mold spores in particular, mold fungus mycelium fragments and others Particles of molds filters out. As a result, the exhaust air that exits the fan or blower contains no molds, mold spores or mycelial fragments more.

The correspondingly cleaned air can be guided in the interior of the organ with corresponding deflecting or air guiding devices, such as channels, flaps, baffles or guide elements made of wood or plastic so that the frequently mold-contaminated surfaces, especially wooden pipes, pipe holders, leather covers and the inner surface of the organ prospectus air-rinsed become.

As a result, a microclimate is created, which is so low that no more molds settle. In addition, the air currents cause the easily dissolving mold spores are deliberately peeled off, be transferred into the air of the interior of the organ and from there again detected by the filter of the fan and filtered out.

Thus, with the method according to the invention, the spore or mycelial fraction number is successively reduced, as a result of which mold fungi are avoided, since in addition the microclimate changes and thus the elimination of the molds and the change in living conditions are accompanied.

For this purpose, the outlet nozzle of the blower is preferably designed like a tube or nozzle and in particular provided with actuators in such a way that the outlet nozzle is movable or is rotatable, in order to flow preferably to the inflowing surface. In addition, a plurality of outlet ports may be present or the outlet port branch and the corresponding branched pipe or nozzle pieces are guided to corresponding components of the organ.

The fan and filter unit are preferably encapsulated sporendicht, so that unwanted mold or its components are not detected unintentionally by the filter.

It is also possible in a preferred embodiment that within the organ at least one sensor for the humidity is present. It is known that mold can thrive as low as 64% relative humidity. A measurement of the humidity, preferably at more than one location of the organ provides information about whether the ventilation is sufficient and whether the intake air is able to change the microclimate accordingly. If it is determined via the sensors that the microclimate does not change in such a way that it falls below the critical relative humidity, the blower can be connected, for example, to a sorption dryer device or to a condenser dryer device.

A sorption dryer may in the simplest case be a sorption dryer cartridge which is present in the airway of the fan. Such a sorption dryer consists for example of silica gel or other materials that have been previously dried and bind the humidity from the environment or the sucked air itself. As a result, the relative humidity is lowered at the outlet side, so that in particular in the circulating mode within the organ housing, the humidity can be lowered accordingly. It is also advantageous that heat the sorption dryer when attaching the moisture, so that in addition the air inside the organ is a little warmer than the air around the organ, which further lowers the relative humidity and prevents condensation. Such Sorptionstrocker may be present as a cartridge and are in particular easily replaceable. A saturated cartridge or cartridge can thus be replaced or regenerated.

Preferably, such a sorption or condenser dryer is provided with a bypass such that when falling below a certain humidity outside air is mixed or sucked air is not passed through the sorption or Kondenstrockner, so that a desired humidity is adjustable. The background is that many parts are made of wood organs, which require a minimum humidity, so as not to distort or dry out.

A condenser dryer or condenser unit removes moisture from the air by cooling the air, increasing the relative humidity above 100% and then precipitating and precipitating the moisture to a refrigerated unit that is essentially the same as a refrigerator.

In a further advantageous embodiment, a heating unit is also provided, which is able to regulate the temperature detected in the interior of the sensor temperature and in particular to regulate so that this temperature is increased compared to the temperature in the rest of the sacred building, so that condensation is avoided. This formation of condensation, in particular on metallic organ parts, often leads to a change in the microclimate to a favorable climate for mold infestation.

The inventive method can be performed on already installed organs, a corresponding trained for the process However, the device according to the invention can already be arranged by the organ builder.

Preferably, the vents are arranged so that a recirculation operation within the organ housing an exhaust air operation with blowing out the air from the organ housing or a vacuum operation, in which the fan is arranged outside the organ and in the organ provides for a negative pressure is guaranteed.

In a further advantageous embodiment of the method, the organ wind, which is used to operate the organ in the game operation, provided with a sorption dryer or condenser and / or a corresponding tempering, so that on the organ wind not particularly cold air from the sacred building in the organ is injected and there leads to an unintentional condensation or accidental entry of mold spores from the environment. For this purpose, the organ wind in the Ausaugbereich be equipped with a HEPA filter.

In addition, in order to achieve all organ pipes in the warm-up operation of the organ, a control is preferably used, which allows to play the respective pipes if necessary to play all the pipes and act with such a small but sufficient air flow that the entire instrument including the pipes warmed up and also with correspondingly dry mold spores and mycelium-fragment-free air is applied, but without generating sound.

In an advantageous embodiment of the method, the organ is also heated in advance of the sacred building over a time control, so that events in the sacred building, usually with a heating and a massive moisture entry u. a. accompanied by respiration, such as As in church services, the organ always has a slightly higher temperature than the building. To ensure that there is no condensation even after such a heating of the room, if a lowering of the temperature of the organ makes sense, this reduction to reduce the room temperature of the building is carried out lagging and kept as possible at the end of the temperature drop slightly above the ambient temperature ,

Although these procedural embodiments represent a certain amount of energy expenditure, they are of great advantage, in particular in the case of already affected organs.

It should be noted that organs represent a huge investment for the parishes and the value of an organ is considerable, so that the conservation effort may be correspondingly high.

The leading and trailing temperature control of the interior of the organ or the air in the interior of the organ can be combined with a corresponding coupling with a humidity control or only with a moisture measurement, so that the relative humidity, which also changes with increasing or decreasing ambient temperature , is kept constant, either by drying incoming air or by supplying humid ambient air. This measure also contributes to the preservation of the organ in addition to the protection against mold, because caused by temperature changes changes in the relative humidity for the materials used are not optimal.

The invention will be explained by way of example with reference to a drawing. It show here:

1 : strongly schematized organ ventilation with air purification according to the invention;

2 another embodiment of organ ventilation;

3 : schematically the arrangement organ ventilation in the surrounding space;

4 : schematically the organ housing with a ventilation after 1 in recirculation mode;

5 : the organ case with an organ ventilation after 1 in exhaust air operation;

6 : the organ case with an organ ventilation after 1 in negative pressure operation.

The device according to the invention 1 includes at least one ventilation unit 2 ( 1 ). The ventilation unit 2 has at least one fan or fan 3 preferably in a fan or fan housing 4 is arranged, which is also preferably spore and dustproof. The fan 3 ensures an air flow along the direction of air flow 5 , Relative to the direction of air flow 5 is in front of the fan a filter box 6 arranged. The filter box 6 is preferably equipped with a so-called HEPA filter, which is also able to filter out fungal spores, dust, mycelial fragments of fungi and their constituents. For this purpose, the filter box can be designed with a replaceable filter cartridge or filter cartridge (not shown), so that the filter box can be exchanged at regular intervals or after prescribed maintenance intervals.

Preferably, the size of the filter box 6 on the circulation performance of the fan 3 tuned so that the fan 3 can circulate sufficiently large amounts of air. The ventilation unit 2 thus also has an appropriate intake manifold or intake at an open intake of the filter box 7 the ventilation unit 2 , In air flow direction 5 is the fan 3 optionally a silencer unit 8th and in particular a pipe silencer unit 8th downstream to which the outlet 9 followed. The outlet nozzle 9 can open in a movable and in particular motor-movable nozzle, which can be rotated and deflected in the spatial directions, that preferably according to a predetermined program, the organ housing can be flown in all its areas.

The outlet nozzle 9 However, it can also lead into a branching piece (not shown), from which a plurality of pipe-shaped or nozzle-shaped branches are guided into the most diverse areas of the organ housing or the interior of the organ up to the organ registers. The fan 3 is hereby preferably adjustable in performance, so that z. B. a circulation of the air is driven only in the innermost region of the organ housing with a lower power, while, for example, in a total circulation of air in the entire organ, including the register, the fan is driven at a high power.

In a further advantageous embodiment of the ventilation unit 2 is in the air flow direction 5 in front of the filter box with HEPA filter 6 an air drying unit 10 arranged. The air drying unit 10 is correspondingly air-conducting with the intake manifold 7 the filter box 6 connected and has a corresponding intake or a corresponding supply, which allows the ambient air, from here into the fan unit 2 to get.

The air drying unit 10 is for example a sorption dryer 10 , wherein the sorption dryer 10 is filled with a Sorptionstrocknermedium. The Sorptionstrocknermedium is in particular in a replaceable cartridge or cartridge, which must be traversed by the air arranged. The Sorptionstrocknermaterial is in particular a granulate and in particular a per se known Sorptionstrocknergranulat such. As silica gel, which is highly moisture-absorbing. Of course, such cartridges or cartridges are interchangeable, these usually being exchanged at predetermined intervals or having ads showing saturation with water. Typically, such cartridges are heat recoverable and reusable. In addition, the sorption material may also be a highly hygroscopic salt, which absorbs water present in the ambient air and binds in the form of a brine. In this case, however, tanks must be provided, which are exchanged after consuming the salt.

The air dryer unit 10 can also consist of a so-called condenser, in which the humidity is reflected on cooled surfaces and is separated from there. Again, tanks are usually present, in which the resulting water is discharged and which must be emptied regularly.

Preferably, the installation of such Lufttrocknereinrichtungen 10 made so that the air dryer device 10 or the cartridges or cartridges contained therein are accessible from the outside, to easily replace them.

In an advantageous embodiment of the device 1 is the device 1 in a room and especially in a church room 15 arranged in 3 is shown only schematically. In this church room 15 is an organ placed, schematically by an organ case 16 is shown. Inside the organ case 16 is the ventilation device 2 , The ventilation device 2 has upstream of a suction valve-like or in particular arranged as a flap valve control device 17 , The control device 17 is via a control device or control device 18 the device 1 taxable.

In this case, the valve or the valve device 17 suction side either on ambient air from the interior of the organ (not shown) or ambient air from the outside of the organ (arrow 19 ). In addition, the valve device 17 be switched so that the sucked air first through a Sorptionstrockner 10a according to the arrow 20 is sucked in or from a preferably arranged outside the organ housing Kondenstrockner 10b according to the arrow 21 be sucked.

In the ventilation device 2 is the HEPA filter and possibly a silencer integrated. In addition, an air heater 22 be present, with which outflowing air according to the arrow 23 is passed through this heating device and then according to the arrow 24 warmed up into the interior of the organ. In addition, the air in the fan 2 was cleaned, according to the arrow 26 unheated to be blown into the organ interior.

In such an embodiment of the device 1 is the controller 18 preferably aligned so that they correspond to the valve means 17 controls and also controls, if the air according to the arrow 23 in the heating device 22 or according to the arrow 26 into the organ interior.

For this purpose, the device preferably also has at least one temperature sensor 27 within the organ housing and preferably a humidity sensor 28 inside the organ case. Of course, a plurality of such humidity and temperature sensors can be arranged distributed in the interior of the organ.

In addition, at least one temperature sensor is preferred 29 and at least one humidity sensor 30 arranged within the space surrounding the organ. Again, of course, a plurality of sensors may be present, so that in the control unit 18 From this, the local temperatures, humidities and thus also the total relative humidities and dew points can be determined. The control device controls in accordance with this data 18 the valve means, so that the valve means 17 the air, if it is too humid, over the sorption dryer 10a or the condenser dryer 10b sucks and thus lower the humidity inside the organ. If the humidity is too low, the amount of air that passes through the sorption dryer 10a is passed, in favor of air, according to the arrow 19 from the outside can be reduced. In addition, air, which corresponds to the arrow 21 through the condenser dryer 10b is performed by switching off the Kondenstrockners 10b also be increased in their humidity.

Preferably, the condenser dryer 10b a performance-controlled condenser dryer.

A corresponding control line 31 is to the valve 17 guided, the control of the control line 31 of the valve 17 in the presence of a condensate dryer 10b via a control line 32 , with the condenser dryer 10b via the control device 18 is coupled.

There is also a control line 33 to the air heating device 22 led to turn this device on and off, when the air according to the arrow 23 is guided by this.

With such a type of trained device 1 Due to the humidity and temperature measurement within the organ and the surrounding space, both the humidity inside the organ and the temperature inside the organ can be controlled very sensitively to influence the microclimate so that molds can not or only very difficult to thrive.

In addition, with such a device, the microclimate within an organ can also be kept constant, which is advantageous for all components of the organ.

Furthermore, the air within the organ is kept pure and in particular kept free from spores and mycelium fragments of molds as well as dust.

In addition, it is conceivable that the complete creation of a ventilation and Temperierungsmanagements of an organ surrounded space 15 the control device 18 also a ventilation of the room 15 via deliberate suction of outside air or opening windows and also controls the heating of the room, so that the temperature control within the organ and the temperature control outside the organ are coupled together so that they can be optimally driven with respect to the dew point on the organ.

In terms of the value of an organ, the amount of equipment required for this purpose is rather low, especially when measured against the value of art treasures within churches, and it ensures the values that organs represent as well as artistic treasures.

By means of the device according to the invention and the method according to the invention, it is made possible to automate as much as possible in the air-conditioning operation and the mold removal operation within an organ and also within a church and thus to make it free from errors of the operating personnel.

Related to the organ case ( 4 . 5 . 6 ) Hereby, the ventilation device according to the invention 2 be operated in recirculation mode ( 4 ), is sucked in the air inside the organ housing and returned to the organ case. In addition, the ventilation device 2 be operated in the exhaust air mode, so that the air moved with the fan is moved out of the organ housing and outside air enters the outside of the organ housing.

Will the ventilation device according to the invention 2 Arranged outside the organ housing and more air sucked out of the organ housing than can flow from the outside, a negative pressure within the organ housing can be ensured with the device according to the invention.
