Abstract

The unit is used to air-condition a room (1), and has reservoirs (2,3) for moisture-absorbing granules, a heater to dry them, a cooler to extract heat from them, and a humidifier. The granules are mounted in the reservoir between perforated metal sheets, to which pipes are fixed. Both reservoirs operate simultaneously, so that when one is drying its airflow and cooling the granules which heat up during the drying process, the other is regenerating its granules using a heating medium which flows through its pipes. A three-way valve combination (12) is arranged behind the reservoirs, in order to guide air from them, along one path into the room or along another discharge path (17). A further valve combination (13) has pipes (8,9) to guide a heating medium into one reservoir and a cooling medium into the other alternately, and both valve combinations are operated simultaneously by a control device.

Description

Die Erfindung betrifft ein Gerät für die Klimatisierung von Räumen, bestehend aus Speichern für die Aufnahme Feuchtigkeit adsorbierenden Granulats, einer Heizvorrichtung für die Trocknung feuchten Granulats, einer Kühlvorrichtung für den Wärmeentzug aus erhitztem Granulat und einer Befeuchtungsvorrichtung für den Wärmeentzug aus der den Speicher durchströmenden Luft sowie aus Heiz- und Kühlmedium zuführenden Rohrleitungen und die Speicher mit dem zu klimatisierenden Raum verbindenden Rohrenleitungen, einem Gebläse für die zu klimatisierende Luft und Ventilen.The invention relates to a device for the air conditioning of rooms, consisting of storage for the absorption of moisture-absorbing granules, a heating device for drying moist granules, a cooling device for extracting heat from heated granules and a humidification device for extracting heat from the air flowing through the storage unit, and from the heating and cooling medium supplying pipelines and the accumulator with the piping connecting the room to be air-conditioned, a blower for the air to be air-conditioned and valves.

Eine derartige Vorrichtung ist für die Klimatisierung von mehreren, in einem Gebäude befindlichen Räumen sowie für die Klimatisierung von Schwimmbädern bekannt geworden. Das Granulat jedes Speichers ist in einem gesonderten Behälter untergebracht. Der Vorgang der Klimatisierung läuft dabei so ab, daß ein Gemisch aus Raumluft und Frischluft durch einen mit Adsorbtionsmaterial gefüllten Speicher geführt wird, wobei diesem Luftgemisch Feuchtigkeit entzogen wird, wodurch sich das Granulat erhitzt. Dieses wird durch in Rohrschlangen durch den Speicher geführtes Kühlmittel gekühlt. Die so erhaltene trockene und relativ kühle Luft wird in einem Luftbefeuchter mit Wasser befeuchtet, wobei durch die Verdunstung des Wassers dieser Luft Wärme entzogen wird. Hierdurch kann sie der Kühlung von Räumen dienen. Das im Laufe dieses Vorganges immer feuchter werdende Granulat muß nach einiger Zeit regeneriert werden, was durch Wasser aus dem Granulat austreibende Erhitzung erfolgt. Wird für diese Erhitzung elektrische Energie verwendet, benutzt man hierzu die Nachtstunden, wo billiger Nachtstrom zur Verfügung steht, während tagsüber die nachts in den Speichern als Trockenheit gespeicherte Energie den Speichern entnommen wird. Dabei sind meist mehr als zwei Speicher vorgesehen, um für Gebäude ausreichende Energielagerkapazitäten zur Verfügung zu haben.Such a device has become known for the air conditioning of several rooms located in a building and for the air conditioning of swimming pools. The granulate of each store is stored in a separate container. The process of air conditioning takes place in such a way that a mixture of room air and fresh air is passed through a store filled with adsorbent material, moisture being removed from this air mixture, as a result of which the granulate heats up. This is through in coils Cooled coolant led through the memory. The dry and relatively cool air thus obtained is humidified with water in a humidifier, heat being removed from this air by the evaporation of the water. As a result, it can be used to cool rooms. The granules, which become increasingly moist in the course of this process, have to be regenerated after some time, which is done by heating expelling water from the granules. If electrical energy is used for this heating, the night hours are used for this, where cheap night electricity is available, while during the day the energy stored as dryness at night is taken from the storage tanks. In most cases, more than two storage facilities are provided in order to have sufficient energy storage capacity available for buildings.

Nur dort, wo auch am Tage genügend billige Energie zur Verfügung steht, wie z.B. nicht mehr anderweitig verwertbare Wärme von Kraftwerken, kann gleichzeitg tagsüber gekühlt und regeneriert werden.Only where there is enough cheap energy available during the day, e.g. Heat from power plants that can no longer be used elsewhere can be cooled and regenerated at the same time during the day.

Die Erfindung geht von der Erkenntnis aus, daß dort, wo an bestimmten Tagen des Jahres Raumkühlung erforderlich ist, auch relativ billige Wärme durch Solarenergie zur Verfügung steht, wenn durch diese Energie Wasser erwärmt wird.The invention is based on the knowledge that, where room cooling is required on certain days of the year, relatively cheap heat is also available through solar energy if water is heated by this energy.

Bei diesen Anlagen zur Klimatisierung von Räumen in Gebäuden hat es sich als nachteilig erwiesen, daß mehrere Räume an eine Anlage geschaltet sind, wodurch Keime und Bakterien von einem Raum zum anderen verschleppt werden. Eine Einzelraum-Klimatisierung mit einer gemeinsamen Regenerierung konnte aufgrund einer eigenen Entwicklung mit Hilfe von flüssigen Sorbtionsmaterialien erzielt werden. Diese haben aber gewichtige Nachteile gegenüber festen granulatförmigen Adsorbern.With these systems for the air conditioning of rooms in buildings it has proven to be disadvantageous that several rooms are connected to one system, whereby germs and bacteria are carried from one room to another. A single room air conditioning with a common regeneration could be achieved due to our own development with the help of liquid sorbent materials. However, these have major disadvantages compared to solid granular adsorbers.

Die Erfindung vermeidet die Nachteile des Standes der Technik. Es ist die Aufgabe der Erfindung, mit einfachen Mitteln ein einfach und raumsparend aufgebautes Gerät zu schaffen, das in der Lage ist, mit wenig Bauaufwand und energetisch günstig eine Einzelraum-Klimatisierung durchzuführen.The invention avoids the disadvantages of the prior art. It is the object of the invention to create a simple and space-saving device with simple means, which is able to carry out a single-room air conditioning with little construction effort and low energy consumption.

Die Erfindung besteht darin, daß die Speicher aus Kulissen gelochter Bleche gefertigt sind, zwischen denen das Granulat gelagert ist und an denen Rohrschlangen befestigt sind, daß beide Speicher gleichzeitig im Betrieb sind, und zwar jeweils der eine Speicher im Zustand der Trockung von ihn durchströmender Luft bei gleichzeitiger Kühlung des sich bei der Trockung von ihn durchströmender Luft erhitzenden Granulats, der andere Speicher im Zustand seiner Regenerierung durch das die Rohrschlangen durchströmende Heizmedium, indem hinter den Speichern eine Dreiweg-Ventilkombination für die Führung der aus den Speichern austretenden Luft einerseits auf einen Weg in den zu klimatisierenden Raum und andererseits auf einen Abluftweg angeordnet ist, und indem eine weitere Ventilkombination in den zu den Speichern Heizmedium und Kühlmedium führenden Rohren angeordnet ist, welche wechselweise in den einen Speicher Heizmedium und in den anderen Speicher Kühlmedium führt, wobei eine Steuerungsvorrichtung vorgesehen ist, die beide Ventilkombinationen zur gleichen Zeit umsteuert.The invention consists in the fact that the accumulators are made of perforated plate sets, between which the granulate is stored and to which coils are fastened, that both accumulators are in operation at the same time, namely one accumulator in the state of drying air flowing through it with simultaneous cooling of the granules heating up during the drying of air flowing through them, the other store in the state of its regeneration by the heating medium flowing through the coils, by a three-way valve combination behind the stores for guiding the air emerging from the stores in one way in the air-conditioned Space and on the other hand is arranged on an exhaust air path, and by a further valve combination is arranged in the pipes leading to the storage heating medium and cooling medium, which leads alternately in one storage heating medium and in the other storage cooling medium, wherein a control device is provided, both of which Valve combinations reversed at the same time.

Dieses Gerät läßt sich mit sehr wenig Raumaufwand herstellen und ist daher insbesondere für die Einzelraum-Klimatisierung geeignet. Es kann mit Abfallwärme oder durch Sonnenenergie erwärmtem Wasser betrieben werden. Die erforderlichen Mengen an Adsorbergranulat sind relativ gering, weil das Gerät während seiner Arbeit sowohl mit dem einen Speicher kühlt als auch gleichzeitig den anderen Speicher regeneriert. Die Kühlung der bei der Kühlung erhitzten Absorbermasse kann in herkömmlicher Weise problemlos erfolgen. Da dieses Gerät für eine Einzelraum-Klimatisierung vorzugsweise bestimmt ist, erfolgt keine Übertragung von Keimen und Bakterien von einem Raum in einen anderen.This device can be manufactured with very little space and is therefore particularly suitable for individual room air conditioning. It can be operated with waste heat or water heated by solar energy. The required amounts of adsorber granulate are relatively small because the device cools while working with one store and regenerates the other store at the same time. The absorption mass heated during the cooling can be cooled in a conventional manner without any problems. Since this device is preferably intended for individual room air conditioning, there is no transmission of germs and bacteria from one room to another.

Die Erfindung besteht auch in einem Verfahren zum Betreiben eines solchen Gerätes für die Klimatisierung von Räumen, das aus zwei Speichern für die Aufnahme Feuchtigkeit adsorbierenden Granulats, einer Heizvorrichtung für die Trocknung feuchten Granulats, einer Kühlvorrichtung für den Wärmeentzug aus erhitztem Granulat und einer Befeuchtungsvorrichtung für den Wärmeentzug aus der den Speicher durchströmenden Luft besteht, wobei dieses Verfahren dadurch gekennzeichnet ist, dadurch gekennzeichnet, daß man in die Speicher gleichzeitig aus dem zu zu klimatisierenden Raum entzogene Luft oder ein Gemisch mit dieser leitet, daß beide Speicher gleichzeitig im Betrieb sind, und zwar jeweils der eine Speicher im Zustand der Trockung von ihn durchströmender Luft bei gleichzeitiger Kühlung des sich bei der Trockung von ihn durchströmender Luft erhitzenden Granulats, der andere Speicher im Zustand seiner Regenerierung durch das die Rohrschlangen durchströmende Heizmedium, und daß man diesen Betriebszustand der Speicher von Zeit zu Zeit wechselt, wobei man die den gekühlten Speicher durchsetzende Luft in den zu klimatisierenden Raum und die den erhitzten Speicher durchsetzende Luft ins Freie leitet.The invention also consists in a method for operating such a device for the air conditioning of rooms, which comprises two stores for holding moisture-absorbing granules, a heating device for drying moist granules, and a cooling device for extracting heat from heated granules and a humidification device for the removal of heat from the air flowing through the store, this method being characterized in that air is simultaneously drawn into the store from the room to be air-conditioned, or a mixture thereof, that both stores simultaneously in the Operation, namely the one storage in the state of drying air flowing through it while cooling the granules heating up during the drying of air flowing through it, the other storage in the state of its regeneration by the heating medium flowing through the coils, and that this The operating state of the storage device changes from time to time, the air passing through the cooled storage device being directed into the room to be air-conditioned and the air passing through the heated storage device being directed outside.

Beim Betrieb kann man dabei so vorgehen, daß man den Wechsel des Betriebszustands der Speicher nach vorgegebenen Zeitabschnitten vornimmt oderdaß man den Wechsel des Betriebszustands der Speicher entsprechend dem Feuchtigkeitsgehalt in den Speichern oder zumindest in dem einen Speicher vornimmt.During operation, one can proceed in such a way that the change in the operating state of the stores takes place after predetermined periods of time or that the change in the operating state of the stores takes place in accordance with the moisture content in the stores or at least in one store.

Energetisch besonders günstig führt man dieses Verfahren so durch, daß man die von dem einen Speicher während dessen Kühlung abgegebene Wärme für die Beheizung des anderen Speichers nutzt.This method is carried out particularly economically in such a way that the heat given off by one store during its cooling is used for heating the other store.

Der Raumaufwand wird besonders gering, wenn die beiden Speicher in einem Behälter untergebracht sind und so angeordnet sind, daß der Behälter beidseits der Speicher in drei Räume geteilt ist, einen Raum (in Strömungsrichtung gesehen) vor den beiden Speichern und je einen weiteren separaten Raum hinter den Speichern.The space requirement is particularly low if the two stores are accommodated in a container and are arranged in such a way that the container is divided into three rooms on both sides of the store, one room (seen in the direction of flow) in front of the two stores and one separate room behind each the stores.

Dabei ist es zweckmäßig wenn der die beiden Speicher aufnehmende Behälter hinter den Speichern in Strömungsrichtung durch eine Trennwand in zwei Teile geteilt ist.It is expedient if the container holding the two stores is divided into two parts behind the stores in the flow direction by a partition.

Baulich läßt sich dieses in besonders einfacher Weise erreichen, wenn die Speicher im Behälter in V-Form angeordnet sind, indem die Speicherkanten sich mittig berühren oder durch eine Wand miteinander verbunden sind und die Speicher im Bereich des Lufteintritts in den Behälter mit den Behälterwandungen verbunden sind.In terms of construction, this can be achieved in a particularly simple manner if the stores in the container are arranged in a V-shape, in that the store edges touch in the middle or are connected to one another by a wall and the stores are connected to the container walls in the region of the air inlet into the container .

Eine Ausführungsform des Speichers kann dabei so gestaltet sein, daß die in V-Form angeordneten Speicher an ihrer Eintrittsseite einen spitzen Winkel zwischen sich einschließen.An embodiment of the memory can be designed so that the V-shaped memory enclose an acute angle between them on its inlet side.

Dabei kann die Auslaßventilkombination bei diesem Speicher so gestaltet sein, daß im Behälter eine verschwenkbare zweiflüglige Klappe als Ventilkombination in Strömungsrichtung hinter den Speichern angebracht ist, welche mit einem Flügel jeweils die Behälterwand und mit dem anderen jeweils die frei im Behälter stehende Kante der beiden Speicher berührt.In this case, the outlet valve combination can be designed in such a way that a pivotable, two-leaf flap is fitted in the container behind the accumulators in the flow direction which touches the container wall with one wing and with the other in each case the free edge of the two stores standing in the container.

Bei dieser Konstruktionsform ist es vorteilhsft, wenn in dem Teil der Behälterwandung, der zwischen den beiden Stellungen der Klappenflügel befindlich ist, eine Austritsöffnung für die den Speicher durchströmende Luft angeordnet ist, während die andere Austritsöffnung für die den Speicher durchströmende Luft im Bereich außerhalb und hinter dem Bewegungsraum der Klappenflügel angeordnet ist.In this form of construction, it is advantageous if an outlet opening for the air flowing through the accumulator is arranged in the part of the container wall which is located between the two positions of the flap wings, while the other outlet opening for the air flowing through the accumulator is arranged in the area outside and behind the movement space of the flap wing is arranged.

Eine andere Ausführungsform des Speichers besteht darin, daß die in V-Form angeordneten Speicher an ihren Eintrittsflächen einen stumpfen Winkel zwischen sich einschließen.Another embodiment of the store consists in that the stores arranged in a V-shape enclose an obtuse angle between them at their entry surfaces.

Bei dieser Ausführungsform ist es zweckmäßig, wenn die Speicher mit ihren Kanten die Behälterwandungen berühren und dadurch im Behälter drei Räume bilden, von denen der an zwei Speicherwandungen grenzende Raum dem Lufteintritt und die lediglich an eine Speicherwand grenzenden Räume Luftaustrittsräume bilden.In this embodiment, it is expedient if the edges of the accumulator touch the container walls and thereby form three spaces in the container, of which the space adjoining two accumulator walls forms the air inlet and the spaces adjoining only one accumulator wall form air outlet spaces.

Diese Ausführungsform des Speichers läßt sich zweckmäßigerweise so gestalten, daß die beiden Luftaustrittsräume jeweils zwei Luftaustrittsöffnungen aufweisen, die sämtlich im Bereich eines Schiebers mit zwei Durchgangsöffnungen liegen, die in einer Stellung des Schiebers mit jeweils der einen Luftaustrittsöffnung jedes der beiden Luftaustrittsräume fluchten und in der anderen Schieberstellung mit der anderen Luftaustrittsöffnung.This embodiment of the memory can expediently be designed in such a way that the two air outlet spaces each have two air outlet openings, all of which are in the region of a slide with two Through openings are located, which are aligned in one position of the slide with the one air outlet opening of each of the two air outlet spaces and in the other slide position with the other air outlet opening.

Diese Anlage arbeitet völlig automatisch, wenn die Steuerungsvorrichtung durch im Granulat angeordneten Feuchtemessern gesteuert ist.This system works completely automatically if the control device is controlled by moisture meters arranged in the granulate.

Damit dieses Gerät auch als Vollklimaanlage arbeiten kann und im Winter der Raumheizung dienen kann, ist es zweckmäßig wenn im zum zu klimatisierenden Raum führenden Luftweg ein weiteres Dreiwegeventil angeordnet ist, welches die Luft entweder über die Befeuchtungsvorrichtung oder über einen die Befeuchtungsvorrichtung umgehenden Bypaß führt.So that this device can also work as a full air conditioning system and can be used to heat the room in winter, it is useful if a further three-way valve is arranged in the air path leading to the room to be air-conditioned, which leads the air either via the humidification device or via a bypass that bypasses the humidification device.

Die Heizvorrichtung 5 ist im gezeichneten Ausführungsbeispiel durch eine Wasser durch Sonnenstrahlung erhitzende Solarzelle realisiert.In the exemplary embodiment shown, the heating device 5 is realized by a solar cell that heats water by solar radiation.

Die Speicher 2,3 bestehen aus Kulissen gelochter Bleche 14, zwischen denen das Granulat 14 gelagert ist und an denen Rohrschlangen 15 befestigt sind. Beide Speicher 2,3 sind gleichzeitig im Betrieb, und zwar wechselweise jeweils der eine Speicher 3 im Zustand der Trockung von ihn durchströmender Luft bei gleichzeitiger Kühlung des sich bei der Trockung von ihn durchströmender Luft erhitzenden Granulats 4, der andere Speicher 2 im Zustand seiner Regenerierung durch das die Rohrschlangen 15 durchströmende Heizmedium. Hinter den beiden Speichern 2,3 befindet sich eine Dreiweg-Ventilkombination 12 für die Leitung der aus den Speichern 2,3 austretenden Luft einerseits auf einen Weg 10 in den zu klimatisierenden Raum 1 und andererseits auf einen Abluftweg 17. Eine weitere Ventilkombination 13 ist in den zu den Speichern 2,3 Heizmedium und Kühlmedium führenden Rohren 8,9 angeordnet, welche wechselweise in den einen Speicher 3 Heizmedium und in den anderen Speicher 2 Kühlmedium führt. Es ist eine nicht dargestellte Steuerungsvorrichtung vorgesehen, die beide Ventilkombinationen 13,17 zur gleichen Zeit in Abhängigkeit von der in den Speichern 2,3 gemessenen Feuchte umsteuert.The stores 2, 3 consist of sets of perforated sheets 14 between which the granules 14 are mounted and to which coils 15 are attached. Both stores 2, 3 are in operation at the same time, alternately one store 3 in the state of drying air flowing through it with simultaneous cooling of the granules 4 heating up during the drying of air flowing through it, the other store 2 in the state of its regeneration through the heating medium flowing through the coils 15. Behind the two stores 2, 3 there is a three-way valve combination 12 for directing the air emerging from the stores 2, 3 on the one hand to the route 10 into the room 1 to be air-conditioned and, on the other hand, to an exhaust air path 17. Another valve combination 13 is in the to the stores 2,3 heating medium and cooling medium leading pipes 8,9 arranged, which leads alternately in one storage 3 heating medium and in the other storage 2 cooling medium. A control device (not shown) is provided which reverses both valve combinations 13, 17 at the same time as a function of the moisture measured in the stores 2, 3.

Die beiden Speicher 2,3 sind gemeinsam in einem Behälter 18 untergebracht und so angeordnet, daß der Behälter 18 beidseits der Speicher 2,3 in drei Räume 19,20, 21 geteilt ist, einen Raum 19 (in Strömungsrichtung gesehen) vor den beiden Speichern 2,3 und je einen weiteren separaten Raum 20,21 hinter den Speichern 2,3.The two stores 2, 3 are housed together in a container 18 and arranged so that the container 18 is divided on both sides of the stores 2, 3 into three rooms 19, 20, 21, a room 19 (seen in the direction of flow) in front of the two stores 2,3 and another separate room 20,21 behind the stores 2,3.

Der die beiden Speicher 2,3 aufnehmende Behälter 18 ist zwischen den Speichern 2,3 in Strömungsrichtung durch eine Trennwand 22 in zwei Teile geteilt. Hinter den Speichern 2,3 befinden sich die Räume 20,21. Die Speicher 2,3 sind im Behälter 18 in V-Form angeordnet, indem die Speicherkanten sich mittig berühren oder durch eine Wand miteinander verbunden sind und an den gegenüberliegenden Seiten mit den Behälterwandungen verbunden sind.The container 18 accommodating the two stores 2, 3 is divided into two parts between the stores 2, 3 in the flow direction by a partition 22. Rooms 20, 21 are located behind stores 2, 3. The stores 2, 3 are arranged in the container 18 in a V-shape in that the storage edges touch each other in the center or are connected to one another by a wall and are connected to the container walls on the opposite sides.

Die in V-Form angeordneten Speicher 2,3 können an ihrer Eintrittsseite einen spitzen Winkel zwischen sich einschließen, wie es in Fig.2 gezeigt ist. Hier ist im Behälter 18 eine verschwenkbare zweiflüglige Klappe als Ventilkombination 12 in Strömungsrichtung hinter den Speichern angebracht, welche mit einem Flügel 23 jeweils die Wand des Behälters 18 und mit dem anderen Flügel 24 jeweils die frei im Behälter stehende Kante 25 der beiden Speicher 2,3 berührt. Die eine Stellung 28 dieser Klappe 12 ist mit ausgezogenen Strichen gezeichnet, die andere Stellung 27 ist gestrichelt gezeichnet.The storages 2, 3 arranged in a V-shape can enclose an acute angle between them on their inlet side, as shown in FIG. Here, a pivotable two-leaf flap is installed in the container 18 as a valve combination 12 in the flow direction behind the accumulators, which with one wing 23 each the wall of the container 18 and with the other wing 24 each free edge 25 of the two accumulators 2, 3 touched. One position 28 of this flap 12 is drawn with solid lines, the other position 27 is drawn in dashed lines.

In dem Teil 26 der Wandung des Behälters 18, der zwischen den beiden Stellungen 27,28 der Klappenflügel 23,24 befindlich ist, ist eine Austrittsöffnung 17 als Abluftweg für die die Speicher 2,3 durchströmende Luft angeordnet, während die andere Austrittsöffnung 30 für die Speicher 2,3 durchströmende Luft im Bereich 31 außerhalb und hinter dem Bewegungsraum der Klappenflügel 23,24 angeordnet ist.In the part 26 of the wall of the container 18, which is located between the two positions 27, 28 of the flap wings 23, 24, an outlet opening 17 is arranged as an exhaust air path for the air flowing through the stores 2, 3, while the other outlet opening 30 for the Air 2.3 flowing through air is arranged in the area 31 outside and behind the movement space of the flap vanes 23, 24.

Wie Fig.3 zeigt, können die in V-Form angeordneten Speicher 2,3 an ihren Eintrittsflächen auch einen stumpfen Winkel zwischen sich einschließen. Die Speicher 2,3 berühren auch hier mit ihren Kanten die Wandungen des Behälters 18 und bilden dadurch im Behälter drei Räume 19,20,21, von denen der an zwei Speicherwandungen grenzende Raum 19 dem Lufteintritt und die lediglich an eine Speicherwand grenzenden Räume 20,21 Luftaustrittsräume bilden. Die beiden Luftaustrittsräume 20,21 weisen jeweils zwei Luftaustrittsöffnungen 32,33 auf, die sämtlich im Bereich eines Schiebers 34 mit zwei Durchgangsöffnungen 35,36 liegen, die in einer Stellung des Schiebers 34 mit jeweils der einen Luftaustrittsöffnung 32 jedes der beiden Luftaustrittsräume 20,21 fluchten und in der anderen Schieberstellung mit der anderen Luftaustrittsöffnung 33. Im gezeichneten Ausführungsbeispiel der Fig.3 fluchtet die Öffnung 33 des Behälterraumes 20 mit der Öffnung 35 im Schieber 34 sowie mit der Abluftleitung 17, während die Öffnung 32 im Behälterraum 21 mit der Öffnung 36 im Schieber 34 sowie mit der zu dem zu klimatisierenden Raum 1 führenden Rohrleitung 10 fluchtet. In dieser Stellung trocknet der Speicher 2, während sich der Speicher 3 in seiner Regenerationsphase befindet. Nach Verstellung des Schiebers 34, die nicht dargestellt ist, fluchtet die Öffnung 32 des Behälterraumes 20 mit der Öffnung 36 im Schieber 34 sowie mit der zu dem zu klimatisierenden Raum 1 führenden Rohrleitung 10, während die Öffnung 32 im Behälterraum 21 mit der Öffnung 36 im Schieber 34 sowie mit der Abluftleitung 17 fluchtet. In dieser Stellung trocknet der Speicher 3, während sich der Speicher 2 in seiner Regenerationsphase befindet.As FIG. 3 shows, the storages 2, 3 arranged in a V-shape can also form an obtuse angle between them at their entry surfaces. The edges 2, 3 here also touch the walls of the container 18 with their edges, thereby forming three spaces 19, 20, 21 in the container, of which the two have storage walls adjoining space 19 form the air inlet and the spaces 20, 21 only adjoining a storage wall form air outlet spaces. The two air outlet spaces 20, 21 each have two air outlet openings 32, 33, all of which are located in the area of a slide 34 with two through openings 35, 36, which, when the slide 34 is in a position, each with one air outlet opening 32 of each of the two air outlet spaces 20, 21 are aligned and in the other slide position with the other air outlet opening 33. In the illustrated embodiment of FIG. 3, the opening 33 of the container space 20 is aligned with the opening 35 in the slide 34 and with the exhaust air line 17, while the opening 32 in the container space 21 with the opening 36 in the slide 34 and with the pipeline 10 leading to the room 1 to be air-conditioned. In this position, the reservoir 2 dries while the reservoir 3 is in its regeneration phase. After adjustment of the slide 34, which is not shown, the opening 32 of the container space 20 is aligned with the opening 36 in the slide 34 and with the pipeline 10 leading to the space 1 to be air-conditioned, while the opening 32 in the container space 21 with the opening 36 in Slider 34 and aligned with the exhaust line 17. In this position, the reservoir 3 dries while the reservoir 2 is in its regeneration phase.

In dem zum zu klimatisierenden Raum 1 führenden Luftweg 10 ist ein weiteres Dreiwegeventil 37 angeordnet, welches die Luft entweder über die Befeuchtungsvorrichtung 7 oder über einen die Befeuchtungsvorrichtung 7 umgehenden Bypaß 38 führt. Die Befeuchtungsvorrichtung 7 für die in den Speichern 2,3 getrocknete Luft erzeugt durch Verdunstung die für die Klimatisierung des Raumes 1 im Sommer benötigte kühle Luft. Wird im Winter die aus den Speichern 2,3 austretende trockene und noch warme Luft über den Bypaß 38 geführt, dient diese der Raumheizung.A further three-way valve 37 is arranged in the airway 10 leading to the room 1 to be air-conditioned the air either leads via the humidification device 7 or via a bypass 38 which bypasses the humidification device 7. The humidification device 7 for the air dried in the stores 2, 3 generates by evaporation the cool air required for the air conditioning of the room 1 in summer. If the dry and still warm air emerging from the stores 2, 3 is led over the bypass 38 in winter, it is used for space heating.

Dieses Gerät saugt durch das Gebläse 11 ein Gemisch aus Frischluft und Raumluft aus dem Raum 1 an, Frischluft über das Einlaßventil 16, Raumluft über das Ventil 29.This device sucks in a mixture of fresh air and room air from room 1 through fan 11, fresh air through inlet valve 16, room air through valve 29.
