Abstract
Description
Die Verringerung der Luftfeuchtigkeit in geschlossenen Räumen ist ein wirksames Mittel gegen Korrosion und andere feuchtigkeitsbedingte Schäden an darin enthaltenen Objekten. Ein gängi ges Verfahren zur Verringerung der Luftfeuchtigkeit ist die Raumbeheizung, meist, in Verbindung mit einer begrenzten Entlüftung der erwärmten Luft. Ferner besteht die Möglichkeit, mittels sta tionärer Klimaanlagen die Raumluft durch Kondensation an Wärmetauschern zu entfeuchten, die durch Verdampfer-Kältemaschinen gekühlt werden. Auch hygroskopische Salze werden zur Ent feuchtung eingesetzt. Es gibt, jedoch zahlreiche Räume, für die diese Verfahren nicht geeignet sind, gleichwohl eine Trocknung der Raumluft wünschenswert erscheint. Dazu gehören zum Beispiel Lager- und Abstellräume, Keller, Garagen, Schiffskajüten, Neubauten, leerstehende Wohnungen usw., in denen eine Beheizung oder die Installation einer stationären Klimaanlage aus wirtschaft lichen Gründen nicht in Betracht kommt. Ferner ist eine Beheizung in manchen Fällen nicht erwünscht (sie fördert den Verfall verderblicher Waren und begünstigt die Korrosion feuchter Ob jekte, z. B. feucht abgestellte Kraftfahrzeuge in geschlossenen Garagen). Eine Trocknung durch hygroskopische Salze scheidet häufig wegen des hohen Wartungsaufwandes aus.Reducing indoor humidity is an effective remedy against Corrosion and other moisture-related damage to objects contained therein. A common one The method of reducing air humidity is, mostly, associated with room heating with limited ventilation of the heated air. There is also the possibility of using sta tional air conditioning systems to dehumidify the room air through condensation on heat exchangers be cooled by evaporator chillers. Hygroscopic salts are also used dampening used. However, there are numerous rooms for which these methods are not suitable, Nevertheless, drying the room air seems desirable. These include, for example Storage and storage rooms, cellars, garages, ship cabins, new buildings, vacant apartments etc., in which heating or the installation of a stationary air conditioning system from economy reasons. Furthermore, heating is not in some cases desirable (it promotes the deterioration of perishable goods and favors the corrosion of damp objects projects, e.g. B. damp parked vehicles in closed garages). A drying through Hygroscopic salts are often eliminated due to the high maintenance requirements.
Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, die Luftfeuch tigkeit in unbeheizten Räumen auf wirtschaftliche Weise zu senken.The invention specified in claim 1 is based on the problem of air humidity reduce the cost in unheated rooms in an economical way.
Dieses Problem wird durch ein Gerät mit den im Patentanspruch 1 genannten Merkmalen gelöst, indem die Entfeuchtung der Luft in unbeheizten Innenräumen durch Kondensation an einer Oberfläche erfolgt, die durch ein Peltier-Element gekühlt wird.This problem is solved by a device with the features mentioned in claim 1 solved by dehumidifying the air in unheated interiors through condensation a surface that is cooled by a Peltier element.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Entfeuchtung der Raumluft unter geringem Energieaufwand erfolgt, im Gegensatz zu einer Raumheizung etwa, welche einen ständigen Wärmeverlust über Wärmeleitungsverluste und Konvektionsverluste durch die zur Entfeuchtung abgeführte Warmluft kompensieren muß. Insbesondere ist keine gesonderte Be- und Entlüftung des Raumes erforderlich, wodurch das zu trocknende Luftvolumen begrenzt bleibt und bereits eine geringe Kühlleistung des als Wärmepumpe arbeitenden Peltier-Elements ausreicht, um bei kontinuierlichem Betrieb die Luftfeuchtigkeit in Räumen üblicher Größe dauerhaft zu senken. Weiterhin lassen sich mit der Erfindung durch die Anwendung von Peltier-Elementen sehr kompakte Geräte konstruieren, die tragbar und flexibel an wechselnden Orten einsetzbar sind. Ein weiterer Vorteil besteht in den geringen Herstellungs- und Betriebskosten. Das im Patentanspruch 1 beschriebene Gerät kann durch Ausnutzung der natürlichen Konvektion ohne bewegliche Teile hergestellt werden. Es ist wartungsfrei und somit für einen Dauereinsatz geeignet. Die entstehende Abwärme führt zu keiner nennenswerten Aufheizung der Raumluft. The advantages achieved with the invention are in particular that the dehumidification the room air takes place with little energy, in contrast to room heating, for example, which causes constant heat loss through heat conduction losses and convection losses must compensate for the warm air discharged for dehumidification. In particular, it is not a separate one Ventilation of the room required, which limits the volume of air to be dried remains and already a low cooling capacity of the Peltier element working as a heat pump sufficient to keep the humidity in rooms of normal size permanently in continuous operation to lower. Furthermore, the invention can be achieved by using Peltier elements design very compact devices that can be used portable and flexible in changing locations are. Another advantage is the low manufacturing and operating costs. That in Claim 1 device described can be made use of natural convection without moving parts are manufactured. It is maintenance-free and therefore suitable for continuous use. The waste heat generated does not lead to any appreciable heating of the room air.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 2 angegeben. Die Weiter bildung nach Patentanspruch 2 ermöglicht es, die getrocknete Luft an einen gewünschten Ort zu leiten, zum Beispiel in Bodennähe, oder Bereiche maximaler Feuchtigkeit. Eine Ausgestaltung zur Verbesserung der Wirtschaftlichkeit ist in Patentanspruch 3 beschrieben und sieht einen Mechanis mus vor, der das Gerät bei zufriedenstellender Luftfeuchtigkeit abschaltet. Die in Patentanspruch 4 beschriebene Variante ermöglicht eine größere Sicherheit gegen Fehlbedienung, da es bei be liebiger Polarität des Peltier-Elements arbeitet. Dies trifft insbesondere zu, wenn das Gerät an einem externen Gleichspannungs-Netzteil betrieben wird. Diese Variante ist in Patentanspruch 5 weiter ausgestaltet. Bei Temperaturen nahe dem Gefrierpunkt kann eine Vereisung der gekühlten Seite des Peltier-Elements vorkommen. Wird die Versorgungsspannung dieser Variante periodisch umgepolt, so bleibt das Gerät durch regelmäßiges Abtauen des Kondensats funktionstüchtig.An advantageous embodiment of the invention is specified in claim 2. The next education according to claim 2 allows the dried air to a desired location conduct, for example near the ground, or areas of maximum moisture. An arrangement for Improvement in economy is described in claim 3 and provides a mechanism must switch off the device when the humidity is satisfactory. The in claim 4 described variant allows greater security against incorrect operation, since it is with be any polarity of the Peltier element works. This is especially true when the device is on an external DC power supply is operated. This variant is in claim 5 further developed. At temperatures close to freezing, icing of the cooled Side of the Peltier element. If the supply voltage of this variant is periodic reversed polarity, the device remains functional by regularly defrosting the condensate.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is in the following described in more detail.
Es zeigt Abb. 1 ein Ausführungsbeispiel der Erfindung nach Patentanspruch 1. Die zu trock nende Raumluft tritt durch eine Lufteintrittsöffnung (1) oben in das Gehäuse ein. Sie trifft auf die Kühlrippen (2) eines (handelsüblichen) Kühlkörpers aus Aluminium, der in der Abbildung durch eine kammartige Struktur schematisch angedeutet ist. Diese Kühlrippen bilden von oben nach unten verlaufende Kanäle, um eine Luftströmung von oben nach unten zu ermöglichen. Sie werden durch ein Peltier-Element (3) gekühlt, so daß es zu einer Konvektionsströmung der Luft von oben nach unten kommt, und so daß ein Teil der Luftfeuchtigkeit an der Oberfläche der Kühlrippen kon densiert. Das Kondenswasser tropft herunter und wird durch den trichterförmigen Gehäuseboden (4) gesammelt. Es wird durch eine Abflußöffnung (5) abgeleitet und kann je nach Bedarf in die Kanalisation geleitet oder in einem Sammelgefäß aufgefangen werden. Die entfeuchtete und leicht gekühlte Luft trifft auf der Rückseite des Peltier-Elements auf einen symmetrischen zum ersten an geordneten Kühlkörper (6), der nunmehr durch die Verlustleistung des Peltier-Elements erwärmt ist und diese Wärme an die vorbeistreichende Luft abgibt. Dies erfüllt zum einen die Funktion, die Konvektionsbewegung der Luft zu erzeugen, die nun von unten nach oben verläuft. Zum ande ren wird die leichte Kühlung der Luft wieder rückgängig gemacht, die den unerwünschten Effekt eine Erhöhung der relativen Feuchtigkeit hätte. Die entfeuchtete Luft wird schließlich durch eine Austrittsöffnung (7) wieder an die umgebende Raumluft abgegeben.It shows Fig. 1 shows an embodiment of the invention according to claim 1. The room air to be dried enters through an air inlet opening ( 1 ) in the top of the housing. It meets the cooling fins ( 2 ) of a (commercially available) aluminum heat sink, which is indicated schematically in the figure by a comb-like structure. These cooling fins form channels from top to bottom to allow air to flow from top to bottom. They are cooled by a Peltier element ( 3 ), so that there is a convection flow of air from top to bottom, and so that part of the air moisture condenses on the surface of the cooling fins. The condensed water drips down and is collected through the funnel-shaped housing base ( 4 ). It is discharged through a drain opening ( 5 ) and can be fed into the sewage system or collected in a collecting vessel as required. The dehumidified and slightly cooled air meets on the back of the Peltier element on a symmetrical to the first arranged heat sink ( 6 ), which is now heated by the power loss of the Peltier element and emits this heat to the air flowing past. On the one hand, this fulfills the function of generating the convection movement of the air, which now runs from bottom to top. On the other hand, the slight cooling of the air is reversed, which would have the undesirable effect of increasing the relative humidity. The dehumidified air is finally released into the ambient air through an outlet ( 7 ).
