Description

Einleitungintroduction

Die Erfindung betrifft eine Vorrichtung zur Verringerung der Luftfeuchtigkeit in einem Raum, umfassend ein Gehäuse mit einem Lufteintrittsquerschnitt und einem Luftaustrittsquerschnitt, eine Ventilatoreinheit zum Ansaugen von Raumluft, einen Kälteerzeuger, mittels dem die angesaugte Luft unterhalb eines Taupunkts abkühlbar ist und eine Kondensatwanne, mittels der ausfallendes Kondensat sammelbar ist.The invention relates to a device for reducing the humidity in a room, comprising a housing having an air inlet cross section and an air outlet cross section, a fan unit for sucking in room air, a cold generator, by means of which the sucked air can be cooled below a dew point and a condensate tray, by means of the precipitating Condensate is collectable.

Darüber hinaus betrifft die Erfindung ein Verfahren zur Verringerung der Luftfeuchtigkeit in einem Raum.Moreover, the invention relates to a method for reducing the humidity in a room.

Stand der TechnikState of the art

Vorrichtungen zur Verringerung der Luftfeuchtigkeit eines Raumes sind aus dem Stand der Technik vielseitig bekannt. Insbesondere beim Neubau von Gebäuden oder bei der Behebung von Feuchteschäden eines Bauwerks werden so genannte Bautrockner verwendet, die der Umgebungsluft Feuchtigkeit entziehen sollen. Dabei wird der Effekt genutzt, dass an kalten Oberflächen Tauwasser ausfällt. Die feuchte Luft wird durch den Bautrockner gesogen und an darin befindlichen Kühlrippen entlang geführt, die die eintretende Luft auf eine Temperatur unterhalb des Taupunktes abkühlen. Hierdurch sammelt sich an den Kühlrippen Kondensat an, das davon abtropft und in einem entsprechenden Behältnis gesammelt und gegebenenfalls abgeführt wird.Devices for reducing the humidity of a room are widely known in the art. In particular, in the construction of new buildings or in the repair of moisture damage to a building so-called building dryer are used to remove moisture from the ambient air. It uses the effect that condensation on cold surfaces precipitates. The moist air is drawn through the building dryer and guided along cooling fins therein, which cool the incoming air to a temperature below the dew point. As a result, accumulates condensate on the cooling fins, which drips off and collected in a corresponding container and optionally discharged.

Aus der DE 10 2013 012 268 A1 geht eine Vorrichtung zur Regulierung der Luftfeuchtigkeit hervor, die einen Ventilator zum Ansaugen der feuchten Luft, einen Verdampfer zum Auskondensieren des Wassers aus der Luft und einen Kondensator zum Wiedererwärmen der getrockneten Luft umfasst. Zusätzlich zu der Entfeuchtung der Luft soll die Vorrichtung auch filtergängige Schmutzpartikel und geruchsbildende Moleküle abscheiden, was durch das Passieren von Luft durch einen lonisator erfolgt. Allerdings werden mittels der bekannten Vorrichtung zwei voneinander separate Luftströme behandelt, einerseits hinsichtlich einer Entfeuchtung und andererseits hinsichtlich einer Reinigung, wobei die beiden Luftströme nach dem Austreten aus der Vorrichtung so gegen eine Raumwand gerichtet werden sollen, dass sie wieder vermischt werden.From the DE 10 2013 012 268 A1 For example, there is provided a device for controlling the humidity which comprises a fan for sucking in the moist air, an evaporator for condensing the water out of the air and a condenser for reheating the dried air. In addition to the dehumidification of the air, the device should also separate filterable dirt particles and odor-forming molecules, which is done by passing air through an ionizer. However, by means of the known device, two separate air streams are treated, on the one hand with respect to dehumidification and, on the other hand, with regard to cleaning, the two air streams, after leaving the device, being directed against a room wall in such a way that they are mixed again.

Typischerweise werden Bautrockner manuell ein- und ausgeschaltet, wobei manche Bautrockner über eine Abschaltautomatik verfügen, die dann eine Abschaltung vorsieht, wenn beispielsweise der maximale Füllstand des Kondensatbehältnisses erreicht ist.Typically, building dryers are manually switched on and off, with some building dryers have an automatic shutdown, which then provides a shutdown, for example, when the maximum level of the condensate tank is reached.

Aufgabetask

Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Verringerung der Luftfeuchtigkeit so weiter zu entwickeln, dass der Betrieb derselben automatisiert abläuft. Analog soll diese Aufgabe auch im Hinblick auf das erfindungsgemäße Verfahren erreicht werden.It is an object of the present invention to further develop a device for reducing the humidity so that the operation of the same automatically runs. Analogously, this task should also be achieved with regard to the method according to the invention.

Lösungsolution

Als Raumbegrenzungsflächen kann beispielsweise eine Raumwand, eine Raumdecke oder der Boden oder ähnliches aufgefasst werden.As room boundary surfaces, for example, a room wall, a ceiling or the floor or the like can be considered.

Die erfindungsgemäße Vorrichtung verfügt demnach über Mittel zur Feststellung der Temperatur und Feuchtigkeit der Raumluft sowie zur Feststellung der Oberflächentemperatur einer Raumbegrenzungsfläche, so dass in Abhängigkeit der gemessenen Werte ein An- oder Ausschalten der Vorrichtung erfolgen kann. Insbesondere ist ein Betrieb der Vorrichtung dann sinnvoll, wenn die Gefahr von Tauwasserausfall an der Oberfläche der Raumwand besteht, also dann, wenn die Oberflächentemperatur der Raumwand unterhalb des Taupunkts liegt, der aus der Raumlufttemperatur und Raumluftfeuchte berechenbar ist. Ein wesentlicher Aspekt ist demnach die Raumfeuchte und die Raumwandoberflächentemperatur. Die Steuerungseinrichtung wertet die gemessenen Werte aus und schaltet die Vorrichtung im Bedarfsfall ein. Umgekehrt erfolgt die Abschaltung der Vorrichtung, wenn sich die gemessenen Werte insofern geändert haben, dass ein Tauwasserausfall an der Oberfläche der Raumwand nicht mehr entstehen kann. Die Messung der Temperatur und Feuchtigkeit der Raumluft kann innerhalb oder außerhalb des Gehäuses erfolgen.The device according to the invention therefore has means for determining the temperature and humidity of the room air and for determining the surface temperature of a room boundary surface, so that the device can be switched on or off depending on the measured values. In particular, an operation of the device is useful if the risk of condensation water on the surface of the room wall, ie when the surface temperature of the room wall is below the dew point, which is calculated from the indoor air temperature and humidity. An essential aspect is therefore the room humidity and the room wall surface temperature. The control device evaluates the measured values and switches on the device if necessary. Conversely, the shutdown of the device, if the measured values have changed in so far that a condensation water on the surface of the room wall can not arise. The measurement of the temperature and humidity of the room air can be done inside or outside the housing.

Im Falle des Betriebs der Vorrichtung ist eine Messung der drei vorgenannten Werte alle 15 bis 30 Minuten sinnvoll. Sind die Feuchtebedingungen in dem Raum unbedenklich und ist die Vorrichtung nicht in Betrieb, reicht es aus, wenn jede Stunde eine Messung der Temperaturen und Luftfeuchtigkeit erfolgt. Selbstverständlich ist eine sinnvolle Taktung von mehreren Faktoren, wie beispielsweise des Raumvolumens, abhängig, so dass auch andere Taktungen denkbar sind. Ebenso ist anstelle einer getakteten Messung eine kontinuierliche Messung der Werte möglich.In the case of operation of the device, a measurement of the three aforementioned values every 15 to 30 minutes makes sense. If the humidity conditions in the room are harmless and the device is not in operation, it is sufficient if a measurement of the temperatures and humidity takes place every hour. Of course, a meaningful timing of several factors, such as the volume of space, dependent, so that other timings are conceivable. Likewise, instead of a pulsed measurement, a continuous measurement of the values is possible.

Die Vorrichtung zeichnet sich dadurch aus, dass sie automatisiert betrieben werden kann und ein manuelles Ein- und Ausschalten entbehrlich ist.The device is characterized in that it can be operated automatically and manual switching on and off is unnecessary.

Die einzelnen Einrichtungen und Komponenten der erfindungsgemäßen Vorrichtungen können innerhalb des Gehäuses oder aber auch außerhalb des Gehäuses angeordnet sein. Auch ist es denkbar, beispielsweise die Einrichtungen zur Temperaturmessung und Feuchtemessung in einer separaten Einheit unterzubringen. Auch kann die Steuerungseinrichtung als separate Einheit vorgesehen werden.The individual devices and components of the devices according to the invention can be arranged inside the housing or else outside the housing. It is also conceivable, for example, to accommodate the devices for temperature measurement and moisture measurement in a separate unit. Also, the controller may be provided as a separate unit.

Der Kälteerzeuger der erfindungsgemäßen Vorrichtung kann einen Kältemittelkreislauf umfassen. Beispielsweise kann es sich um eine elektrisch betriebene Kompressionskältemaschine handeln, bei der ein Kältemittel in einem geschlossenen Kreislauf geführt wird. Flüssiges Kältemittel wird in einem Verdampfer in einen gasförmigen Zustand überführt, wobei Kälte entsteht. Diese Kälte wird genutzt, um die Feuchtigkeit der Raumluft zu kondensieren. Das gasförmige Kältemittel wird dann über einen Kompressor wieder verflüssigt, wobei Wärme entsteht. Die bei der Kompression erzeugte Wärme kann zur Wärmerückgewinnung verwendet werden, indem die entfeuchtete Raumluft an einem mit dem Kompressor gekoppelten Wärmeüberträger vorbeigeführt wird. Die die Vorrichtung über die Luftaustrittsfläche verlassene, entfeuchtete Raumluft ist somit (wegen der reduzierten Wärmekapazität nach der Entfeuchtung) auch wärmer als die vormals in die Vorrichtung eintretende Raumluft. Andere Arten eines Kältemittelkreislaufs sind gleichfalls denkbar.The cold generator of the device according to the invention may comprise a refrigerant circuit. For example, it may be an electrically operated compression refrigeration machine, in which a refrigerant is guided in a closed circuit. Liquid refrigerant is converted into a gaseous state in an evaporator, whereby cold arises. This cold is used to condense the humidity of the room air. The gaseous refrigerant is then re-liquefied via a compressor, generating heat. The heat generated in the compression can be used for heat recovery by the dehumidified room air is passed to a coupled with the compressor heat exchanger. The dehumidified room air leaving the device via the air outlet surface is thus (because of the reduced heat capacity after dehumidification) also warmer than the room air previously entering the device. Other types of refrigerant circuit are also conceivable.

Alternativ kann der Kälteerzeuger auch von einem Peltier-Element gebildet werden. Auf diese Weise lässt sich elektrische Energie direkt in Kälte umwandeln.Alternatively, the cold generator can also be formed by a Peltier element. In this way, electrical energy can be converted directly into cold.

Als Vorrichtung zur Messung der Oberflächentemperatur einer Wand des Raums eignet sich insbesondere ein Infrarot-Temperaturmessgerät, das die Oberflächentemperatur berührungslos misst. Somit ist es nicht erforderlich das Temperaturmessgerät an der Wand zu installieren und möglicherweise eine Datenübertragung per Kabel oder Funk zu ermöglichen, vielmehr kann sich das Infrarot-Temperaturmessgerät an der Vorrichtung selbst befinden, beispielsweise im Bereich der Steuerungseinrichtung.As an apparatus for measuring the surface temperature of a wall of the room, in particular, an infrared temperature measuring device is suitable, which measures the surface temperature without contact. Thus, it is not necessary to install the temperature measuring device on the wall and possibly enable data transmission by cable or radio, but rather the infrared temperature measuring device are located on the device itself, for example in the region of the control device.

Die Erfindung vorteilhaft ausgestaltend ist ein Heizregister vorgesehen, mittels dem die entfeuchtete Luft vor Austritt aus dem Luftaustrittsquerschnitt erwärmbar ist. Somit kann die Temperatur der entfeuchteten Luft - abgesehen von einer eventuellen Erwärmung durch die zuvor erwähnte Wärmerückgewinnung - erhöht werden, wobei die Raumluft jedoch nicht insgesamt erwärmt wird, sondern lediglich auf die Ausgangstemperatur. Dieser Effekt hat wiederum zur Folge, dass die Raumluft bei gleichbleibender Raumtemperatur weniger feucht ist.The invention advantageously ausgestaltend a heating coil is provided by means of which the dehumidified air is heated before exiting the air outlet cross-section. Thus, the temperature of the dehumidified air - except for any heating by the aforementioned heat recovery - can be increased, but the room air is not heated as a whole, but only to the starting temperature. This effect in turn means that the room air is less humid at constant room temperature.

Die Qualität der Raumluft kann ferner gesteigert werden, indem die erfindungsgemäße Vorrichtung einen Filter aufweist, der in einem Bereich des Lufteintrittsquerschnitts angeordnet ist. Die in die Vorrichtung strömende Raumluft passiert somit den Filter, wobei es sich je nach gewünschten Anforderungen um mechanische oder chemische Filter handeln kann. Im Sinne einer eventuell gewünschten Kompaktheit der Vorrichtung und zum Schutz des Filters sollte der Filter in Strömungsrichtung der Raumluft betrachtet hinter dem Lufteintrittsquerschnitt angeordnet sein, so dass dieser geschützt im Gehäuse der Vorrichtung untergebracht ist.The quality of the room air can be further increased by the device according to the invention comprises a filter which is arranged in a region of the air inlet cross section. The air flowing into the device thus passes through the filter, which may be mechanical or chemical filters depending on the desired requirements. In terms of a possibly desired compactness of the device and to protect the filter, the filter should be arranged in the flow direction of the room air behind the air inlet cross-section, so that it is housed protected in the housing of the device.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass der Luftaustrittsquerschnitt von einem Luftaustrittsquerschnitt mindestens einer Düse gebildet wird, mittels der eine turbulente Strömung der aus dem Gehäuse austretenden Luft erzeugbar ist. Infolge eines turbulent austretenden Volumenstroms aus der Vorrichtung wird bei Austritt der entfeuchteten Luft eine Vermischung der entfeuchteten, eventuell erwärmten, Luft mit der Raumluft hervorgerufen, so dass die Eigenschaften der Luft in dem Raum insgesamt vergleichmäßigt werden. Selbstverständlich kann der Luftaustrittsquerschnitt von mehreren Düsen gebildet werden.According to a particularly preferred embodiment of the invention it is provided that the air outlet cross-section is formed by an air outlet cross-section of at least one nozzle, by means of which a turbulent flow of the air emerging from the housing can be generated. As a result of a turbulently emerging volume flow from the device, a mixture of the dehumidified, possibly heated, air is caused with the room air at the outlet of the dehumidified air, so that the properties of the air in the room are made uniform overall. Of course, the air outlet cross section can be formed by a plurality of nozzles.

Hinsichtlich eines Verfahrens gemäß dem Oberbegriff des Anspruchs 8 wird die zuvor erwähnte Aufgabe durch eine Messung der Lufttemperatur der in das Gehäuse eintretenden Raumluft, eine Messung der Luftfeuchte der in das Gehäuse eintretenden Raumluft, eine Messung der Oberflächentemperatur einer Wand des Raums, eine Auswertung der gemessenen Werte sowie eine Ansteuerung der Vorrichtung gelöst. Wie bereits zu der erfindungsgemäßen Vorrichtung beschrieben, kann durch Auswertung der gemessenen Werte verfolgt werden, ob Tauwasser an der Oberfläche der Wand des Raumes ausfällt oder nicht. In Abhängigkeit der gemessenen Werte erfolgt eine Fortführung, Beendigung oder ein Beginn des erfindungsgemäßen Verfahrens.With regard to a method according to the preamble of claim 8, the aforementioned object is achieved by measuring the air temperature of the room air entering the housing, measuring the air humidity of the room air entering the housing, measuring the surface temperature of a wall of the room, an evaluation of the measured Values and a control of the device solved. As already described for the device according to the invention, it can be tracked by evaluating the measured values whether condensation water precipitates on the surface of the wall of the room or not. Depending on the measured values, a continuation, termination or commencement of the method according to the invention takes place.

Die Abkühlung der eintretenden Raumluft kann beispielsweise mittels eines Kältemittelkreislaufs oder eines Peltier-Elements erfolgen.The cooling of the incoming room air can be done for example by means of a refrigerant circuit or a Peltier element.

Vorteilhafterweise wird die eintretende Raumluft nach dem Ausfall des Kondensats, also der entfeuchtete Volumenstrom, so geführt, dass sie durch die bei der Kälteerzeugung entstandene Abwärme ihrerseits erwärmt wird.Advantageously, the incoming room air after the failure of the condensate, so the dehumidified flow, so guided that it is in turn heated by the waste heat generated during cooling.

Um einen weiteren Heizeffekt zu erzielen, kann gemäß einer Weiterbildung des erfindungsgemäßen Verfahrens vorgesehen sein, dass die entfeuchtete Raumluft mittels eines Heizregisters erwärmt wird.In order to achieve a further heating effect, it can be provided according to a development of the method according to the invention that the dehumidified room air is heated by means of a heating register.

Ferner kann es vorgesehen sein, dass die eintretende Raumluft gefiltert wird, wobei mechanische Filter Verwendung finden können.Furthermore, it can be provided that the incoming room air is filtered, with mechanical filters can be used.

Wird die entfeuchtete Raumluft über mindestens eine Düse turbulent aus dem Gehäuse ausgeströmt, so vermischt sich der entfeuchtete Volumenstrom mit der Raumluft und es entstehen homogene Luftverhältnisse.If the dehumidified room air flows turbulently out of the housing via at least one nozzle, the dehumidified volume flow mixes with the room air and homogeneous air conditions are created.

Schließlich sei angemerkt, dass die verschiedenen Merkmale der Unteransprüche je einzeln für sich oder zu mehreren in beliebigen Kombinationen bei Varianten der Erfindung verwirklicht sein können.Finally, it should be noted that the various features of the subclaims can be implemented individually for themselves or for a plurality of combinations in variants of the invention.

Die vorstehend beschriebene Erfindung wird nachfolgend anhand eines Ausführungsbeispiels, das in den Figuren dargestellt ist, näher erläutert.The invention described above will be explained in more detail using an exemplary embodiment which is illustrated in the figures.

FIG. 2:
schematic representation of the device FIG. 1 ,

In der Figur 1 ist eine erfindungsgemäße Vorrichtung 1 zur Verringerung der Luftfeuchte in einem Raum 2 gezeigt, wobei die Vorrichtung 1 in Längsrichtung (Pfeil 3) geschnitten ist. Die Vorrichtung 1 umfasst ein quaderförmiges Gehäuse 4, das aus einzelnen Blechabschnitten 5 zusammengesetzt ist. An einer Unterseite 6 des Gehäuses 4 sind zwei von vier Rollen 7 erkennbar, die ein Verfahren der Vorrichtung 1 ermöglichen. Die Vorrichtung 1 wird entlang ihrer Längsrichtung (Pfeil 3) durchströmt, wobei der die Vorrichtung 1 durchströmende Luftvolumenstrom an verschiedenen Etappen mittels Pfeilen 8, 9, 10, 11, 12 dargestellt ist. Raumluft (Pfeil 8) wird über einen Ventilator 13, der in Strömungsrichtung 14 betrachtet an einem Ansaugende des Gehäuses 4 angeordnet ist, in das Gehäuse 4 gesogen, wobei die Raumluft (Pfeil 8) ein Ansauggitter 15, das einen Lufteintrittsquerschnitt 16 in die Vorrichtung 1 definiert, sowie einen hinter dem Ansauggitter 15 befindlichen Ansaugfilter 17 passiert. Die gefilterte Raumluft (Pfeil 9) strömt daraufhin in einen Verdampfer 18, wo sie an dessen Kühlflächen so stark abgekühlt wird, dass Kondensat ausfällt. Das Kondensat wird in einer Kondensatwanne 19 aufgefangen, die trichterförmig ausgebildet ist und einen Ablauf 20 besitzt. An den Ablauf 20 schließt sich eine Rohrleitung 21 an, die an beziehungsweise durch das Gehäuse 4 führt, wo ein öffen- und schließbarer Kondensatablaufstutzen 22 positioniert ist.In the FIG. 1 a device 1 according to the invention for reducing the humidity in a space 2 is shown, wherein the device 1 in the longitudinal direction (arrow 3) is cut. The device 1 comprises a cuboidal housing 4, which is composed of individual sheet metal sections 5. On an underside 6 of the housing 4, two of four rollers 7 can be seen, which enable a method of the device 1. The device 1 is flowed through along its longitudinal direction (arrow 3), wherein the device 1 flowing through Air flow at different stages by arrows 8, 9, 10, 11, 12 is shown. Room air (arrow 8) is sucked into the housing 4 via a fan 13, which is arranged in the flow direction 14 at a suction end of the housing 4, wherein the room air (arrow 8) an intake grille 15, the air inlet cross-section 16 in the device. 1 defined, as well as located behind the intake grille 15 intake filter 17 happens. The filtered room air (arrow 9) then flows into an evaporator 18, where it is cooled to the cooling surfaces so strong that condensate precipitates. The condensate is collected in a condensate tray 19, which is funnel-shaped and has a drain 20. The drain 20 is followed by a pipe 21, which leads to or through the housing 4, where an openable and closable condensate drain pipe 22 is positioned.

Ausgehend von dem Verdampfer 18 gelangt die nunmehr entfeuchtete Raumluft in eine Kammer 23, in der auf sie Kondensationswärme eines Kältemittels, das von einem unterhalb der Kammer 23 befindlichen Kompressors 24 verdichtet wird, übertragen wird. Dabei wird die eingangs gekühlte und entfeuchtete Raumluft wieder erwärmt und verlässt die Kammer 23 als entfeuchtete, erwärmte Raumluft (Pfeil 10). Der Verdampfer 18, der Kompressor 24, ein nicht gezeigtes Expansionsventil und Wärmetauscherflächen der Kammer 23 bilden Bauteile eines Kältemittelkreislaufs. Typischerweise ist der Kondensationstrockner 25 elektrisch betrieben.Starting from the evaporator 18, the now dehumidified room air passes into a chamber 23 in which condensation heat of a refrigerant, which is compressed by a compressor 24 located below the chamber 23, is transferred to it. In this case, the initially cooled and dehumidified room air is reheated and leaves the chamber 23 as dehumidified, heated room air (arrow 10). The evaporator 18, the compressor 24, an expansion valve, not shown, and heat exchange surfaces of the chamber 23 constitute components of a refrigerant circuit. Typically, the condensation dryer 25 is electrically powered.

Nach dem Austritt der entfeuchteten Raumluft aus der Kammer 23 wird die Raumluft (Pfeil 10) durch ein elektrisch betriebenes Heizregister 26 geführt, wo sie weiter erwärmt wird. Anschließend passiert die gekühlte, entfeuchtete und wieder erwärmte Raumluft den Ventilator 13 und gelangt über Düsen 27 aus der Vorrichtung 1 in den Raum 2 zurück. In der Figur 1 sind zwei von vier oder sechs Düsen 27 erkennbar. Die Summe der Luftaustrittsquerschnitte 28 der Düsen 27 bildet den gesamten Luftaustrittsquerschnitt der Vorrichtung 1. Der Volumenstrom (Pfeil 12) verlässt die Düsen 27 als turbulenter Volumenstrom, der sich mit umgebender unbehandelter Raumluft mischt. Hierdurch entstehen gleichmäßige Luftverhältnisse und einer Luftschichtung wird vorgebeugt.After the discharge of the dehumidified room air from the chamber 23, the room air (arrow 10) is passed through an electrically operated heating register 26, where it is further heated. Subsequently, the cooled, dehumidified and reheated room air passes through the fan 13 and returns via nozzles 27 from the device 1 in the space 2. In the FIG. 1 two of four or six nozzles 27 can be seen. The sum of the air outlet cross sections 28 of the nozzles 27 forms the entire air outlet cross section of the device 1. The volume flow (arrow 12) leaves the nozzle 27 as a turbulent volume flow, which mixes with surrounding untreated room air. This results in uniform air conditions and air stratification is prevented.

Die Anordnung des Heizregisters 26 ist optional, wobei es bei der Anordnung desselben von Vorteil ist, wenn zusätzlich noch ein Sicherheitstemperaturbegrenzer 29 nachgeschaltet ist, mittels dem das Heizregister 26 ausschaltbar ist, wenn die entfeuchtete und erwärmte Raumluft einen oberen Grenzwert überschreitet.The arrangement of the heating register 26 is optional, wherein it is advantageous in the arrangement thereof, if in addition a safety temperature limiter 29 is connected downstream, by means of which the heating register 26 is switched off when the dehumidified and heated room air exceeds an upper limit.

Kurz bevor die Raumluft in die Düsen 27 gelangt, kann ein Strömungswächter 30 angeordnet sein. Wird von dem Strömungswächter 30 keine Luftströmung mehr wahrgenommen, wird die Vorrichtung 1 ebenfalls abgeschaltet.Shortly before the room air enters the nozzles 27, a flow switch 30 may be arranged. If no air flow is perceived by the flow monitor 30, the device 1 is also switched off.

In einem Bereich zwischen dem Lufteintrittsquerschnitt 16 in die Vorrichtung 1 und dem Verdampfer 18 ist eine Einrichtung 31 zur Messung der Lufttemperatur und eine Einrichtung 32 zur Messung der Luftfeuchtigkeit angeordnet, so dass die Temperatur und die Feuchtigkeit der in die Vorrichtung 1 eintretenden Raumluft 8 gemessen werden. Ferner ist die erfindungsgemäße Vorrichtung 1 mit einer Einrichtung 33 zur Messung der Oberflächentemperatur in Form eines Temperatursensors ausgestattet, der mittels Infrarot die Temperatur einer nicht in der Figur dargestellten Raumwandoberfläche misst. Alle gemessenen Daten werden an eine Steuerungseinrichtung 34 zur Auswertung der erfassten Werte geleitet, wobei die Steuerungseinrichtung 34 ferner zur Ansteuerung der Vorrichtung 1 dient. Ergeben die gemessenen Werte, dass ein Tauwasserausfall an der Raumwandoberfläche auftritt, so wird die Vorrichtung 1 eingeschaltet. Ist ein Tauwasserausfall an der Raumwandoberfläche nicht oder nicht mehr zu erwarten, bleibt die Vorrichtung 1 ausgeschaltet oder wird ausgeschaltet. Die Steuerungseinrichtung 34 ist in der Figur 1 auf dem Gehäuse 4 angeordnet und an selbigem befestigt.In a region between the air inlet cross section 16 in the device 1 and the evaporator 18, a device 31 for measuring the air temperature and a device 32 for measuring the humidity is arranged so that the temperature and humidity of the entering into the device 1 room air 8 are measured , Furthermore, the device 1 according to the invention is equipped with a device 33 for measuring the surface temperature in the form of a temperature sensor which measures the temperature of a room wall surface not shown in the figure by means of infrared. All measured data are sent to a control device 34 for evaluation of the detected values, wherein the control device 34 also serves to control the device 1. If the measured values indicate that a condensation water leak occurs on the wall surface, the device 1 is switched on. If a condensation water leak on the room wall surface is not or no longer to be expected, the device 1 remains switched off or is switched off. The control device 34 is in the FIG. 1 arranged on the housing 4 and attached to selbigem.

In der Figur 2 ist ein Ablaufschema bezüglich der Funktion der erfindungsgemäßen Vorrichtung 1 aus Figur 1 dargestellt, wobei eine Raumwand 35 angedeutet ist. In der Figur 2 sind die Einrichtungen zur Messung der Temperatur 31, zur Messung der Luftfeuchtigkeit 32 und zur Messung der Oberflächentemperatur 33 in einer Einheit zusammengefasst, wobei die erfassten Daten an die Steuerungseinrichtung 34 weitergegeben werden. Ist auf Basis der in der Steuerungsvorrichtung 34 ausgewerteten Daten ein Betrieb der Vorrichtung 1 sinnvoll, wird diese automatisch von der Steuerungsvorrichtung 43 in Betrieb genommen, was bedeutet, dass ein Einschalten des Ventilators 13 des Kondensationstrockners 25 und des Heizregisters 26 erfolgt. Die Raumluft (Pfeil 8) wird entfeuchtet und erwärmt und verlässt die Vorrichtung 1 durch die Düsen 27.In the FIG. 2 is a flowchart relating to the function of the device 1 according to the invention FIG. 1 shown, wherein a room wall 35 is indicated. In the FIG. 2 For example, the means for measuring the temperature 31, for measuring the humidity 32 and for measuring the surface temperature 33 are combined in one unit, the detected data being passed on to the control unit 34. If operation of the device 1 makes sense on the basis of the data evaluated in the control device 34, it is automatically put into operation by the control device 43, which means that the fan 13 of the condensation dryer 25 and the heating register 26 are switched on. The room air (arrow 8) is dehumidified and heated and leaves the device 1 through the nozzles 27th
