Description

Ein unkontrollierter Luftaustausch zwischen der Luft in einem Raum und der Außenluft, wie er nicht nur beim übli­chen Öffnen von Türen und Fenstern stattfindet, sondern bislang sich auch als "latenter" bzw. "natürlicher" Luft­austausch durch undichte Tür- und Fensterfugen abgespielt hat, führt in der Regel zu einem unerwünschten Verlust der mit der Raumluft fortgeführten Wärme. Aus Gründen der Ener­gieeinsparung hat man daher Wert auf optimale Abdichtung der Tür- und insbesondere der Fensterfugen gelegt; der "natür­liche" Luftaustausch wird dadurch unterbrochen oder zumin­dest gehemmt.
Wasserdampf, der in einem dergestalt abgedichteten Raum von der darin sich aufhaltenden Personen und darüber hinaus von Pflanzen sowie durch Wasserverdunstung, Wasserdampf ausschei­dende Einrichtungen, Geräte und dergl. produziert wird, läßt die Luftfeuchte im Raum steigen, was sich auf die den Raum einschließenden Bauteile nachteilig auswirken kann und das Raumklima ungünstig beeinflußt, d.h. durch eine zeitlich be­grenzte, gründliche Lüftung mit intensivem Luftaustausch zwi­schen Innen- und Außenluft, die Luftfeuchte und gegebenen­falls auch die Lufttemperatur wieder normalisiert werden. Diese Art der Lüftung kann aber Ursache einer ungünstigen Wärmebilanz sein, weil Gradmesser für den Luftungseffekt in der Regel das subjektive Empfinden der die Lüftung vornehmen­den Person ist, was oft zu einer unnötig langen Lüftungsdauer mit entsprechendem Wärmeverlust führt.An uncontrolled exchange of air between the air in a room and the outside air, which not only occurs when doors and windows are opened normally, but has also previously taken place as "latent" or "natural" air exchange through leaky door and window joints usually to an undesirable loss of the heat carried away with the room air. For reasons of energy saving, great value has therefore been placed on optimal sealing of the door and in particular the window joints; the "natural" air exchange is interrupted or at least inhibited.
Water vapor, which is produced in a room sealed in this way by the people in it and, in addition, by plants as well as by water evaporation, water vapor-separating devices, devices and the like, increases the air humidity in the room, which is disadvantageous for the components enclosing the room can have an impact and adversely affect the indoor climate, ie be normalized again through a temporary, thorough ventilation with intensive air exchange between indoor and outdoor air, the air humidity and possibly also the air temperature. However, this type of ventilation can be the cause of an unfavorable heat balance, because the measure of the ventilation effect is usually the subjective feeling of the person doing the ventilation, which often leads to an unnecessarily long ventilation period with corresponding heat loss.

Es ist bekannt, Fenster, gegebenenfalls auch Türen, mit Lüftungsklappen, Lüftungsgittern oder dergl. zu versehen, die von Hand verstellbar sind, un eine Verbindung mit ver­änderbarem Querschnitt zwischen Innen- und Außenluft her­zustellen. Mit diesen von Hand zu bedienenden Mitteln läßt sich ein kontinuierlicher Austausch der Luft in einem Raum mit der Außenluft bewerkstelligen. Auch hier besteht aber die Gefahr einer ungünstigen Wärmebilanz, weil Gradmesser für die den Lüftungseffekt bedingende Bedienung der Lüf­tungsklappen u.ä. auch jetzt das subjektive Empfinden der Bedienungsperson ist und weil überdies mit einer theoretisch notwendigen dauernden Beobachtung des Lüftungserfolgs in der Regel nicht zu rechnen ist.It is known to provide windows, possibly also doors, with ventilation flaps, ventilation grilles or the like, which can be adjusted by hand, and to produce a connection with a variable cross section between inside and outside air. With these manually operated means, a continuous exchange of the air in a room with the outside air can be accomplished. However, here too there is a risk of an unfavorable heat balance, because a gauge for the operation of the ventilation flaps and the like, which results in the ventilation effect. is also the subjective feeling of the operator and because, moreover, a theoretically necessary permanent observation of the ventilation success is generally not to be expected.

Es ist ferner auch bekannt, Lüftungsklappen und dergl. durch mechanische Stellglieder, die motorisch, also unter Zufuhr von Hilfsenergie, betrieben werden, zu betätigen. Hier be­steht die Möglichkeit, die Stellmotoren durch Sensoren, z.B. für die Lufttemperatur, zu schalten und so eine objek­tive, optimale Lüftungsregelung durchzuführen. Diese Art der automatischen Lüftungsregelung mit Zufuhr von Hilfs­energie ist indessen apparativ sehr aufwendig und mit trag­baren Kosten in bestehende Gebäude in der Regel nicht nach­träglich einzuführen.It is also known to actuate ventilation flaps and the like by mechanical actuators which are operated by a motor, that is to say with the supply of auxiliary energy. Here it is possible to switch the servomotors using sensors, eg for the air temperature, and thus to carry out an objective, optimal ventilation control. This type of automatic ventilation control with supply of auxiliary energy is, however, very complex in terms of equipment and generally cannot be introduced retrospectively into existing buildings at affordable costs.

Die Erfindung geht aus von einer Lüftungseinrichtung zum bedarfs­orientierten Austausch der Luft in einem Raum mit der Außenluft mittels eines eine veränderbare Durchgangsöffnung für den Luft­wechsel aufweisenden Lüftungselementes. Ihr liegt die Aufgabe zu­grunde, eine solche Einrichtung zu schaffen, die ständig eine ob­jektive, optimale Lüftungsregelung mit einfachen Mitteln und ohne Zufuhr von Hilfsenergie ermöglicht, wobei die Wärmeverluste im Raum gering gehalten werden sollen.The invention is based on a ventilation device for the demand-oriented exchange of air in a room with the outside air by means of a ventilation element having a changeable through opening for the air change. It is based on the task of creating such a device that enables an objective, optimal ventilation control with simple means and without the supply of auxiliary energy, while keeping the heat losses in the room low.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß für die Steuerung des Luftaustausches ein auf die Feuchte der Raumluft reagierender Sensor vorgesehen ist, der als mechanisches Stellor­gan zum stetig veränderbaren Öffnen und Schließen der Durchgangs­öffnung in Abhängigkeit von der Raumluftfeuchte - oder als Ventil­element selbst ausgebildet ist.The object is achieved in that a sensor which reacts to the humidity of the room air is provided for controlling the air exchange and which is designed as a mechanical actuator for continuously changing opening and closing of the passage opening depending on the room air humidity - or as a valve element itself.

Der Erfindung liegt die Oberlegung zugrunde, daß eine wesentliche Vereinfachung der Steuerung des bedarfsorientierten Luftaustau­sches bewirkt werden kann, wenn ein auf die Feuchtigkeit der Raumluft reagierender Sensor nicht über einen Hilfsmotor wirkt, sondern so ausgebildet ist, daß er selbst als Stellorgan oder als Ventilverschlußelement ausgebildet ist.The invention is based on the principle that a significant simplification of the control of the demand-oriented air exchange can be effected if a sensor reacting to the humidity of the room air does not act via an auxiliary motor, but is designed so that it is designed as an actuator or as a valve closure element .

Die Größe der Stellenergie bei einem solchen unmittelbar von ei­nem Sensor betätigten Lüftungselement ist nicht sehr groß. Um trotzdem kurze Steuerzeiten und ausreichende Lüftungsquerschnitte bei allen Betriebsverhältnissen zu erreichen, kann es zweckmäßig sein, zusätzlich zu dem von einem Feuchtesensor gesteuerten Lüf­tungselement ein weiteres Lüftungselement vorzusehen, das durch einen auf die Temperatur der Außenluft reagierenden Sensor geöff­net oder geschlossen wird. Wenn dabei die Sensoren so ausgebildet sind, daß bei niedriger Außentemperatur das temperaturgesteuerte Lüftungselement geschlossen bleibt und sich erst bei höheren Au­ßentemperaturen allmählich öffnet, können die Abmessungen beider Lüftungselemente und damit deren Trägheit kleiner sein. Außerdem werden dadurch die Wärmeverluste im Raum verringert. Vorteilhaft ist es weiter, die Lüftungselemente als reibungs- und trägheitsar­ me Walzenventile auszubilden, deren Hohlzylinder durch eine hygro­phile Faser oder eine Bimetallspirale als Stellelemente verdrehbar sein können.The size of the actuating energy in such a ventilation element actuated directly by a sensor is not very large. In order to achieve short control times and adequate ventilation cross-sections in all operating conditions, it may be advisable to provide a ventilation element controlled by a humidity sensor, which is opened or closed by a sensor that responds to the temperature of the outside air. If the sensors are designed so that the temperature-controlled ventilation element remains closed at a low outside temperature and only opens gradually at higher outside temperatures, the dimensions of both ventilation elements and thus their inertia can be smaller. It also reduces heat loss in the room. It is also advantageous if the ventilation elements are low in friction and inertia me to form roller valves, the hollow cylinders of which can be rotated as control elements by a hygrophile fiber or a bimetal spiral.

Für Anwendungen, bei denen ein dichter Abschluß der Lüftungsele­mente auch bei starker Windanströmung notwendig ist, kann ein senkrechter Flachschieber zweckmäßiger sein. Für die dabei er­forderlichen höheren Stellkräfte ist als Feuchtesensor ein Band aus hygrophilen parallelen Fasern vorgesehen. Die Rückstellung er­folgt durch das Eigengewicht des Schiebers.For applications in which a tight seal of the ventilation elements is necessary even with strong wind, a vertical flat slide can be more appropriate. For the higher positioning forces required, a band of hygrophilic parallel fibers is provided as a moisture sensor. It is reset by the slider's own weight.

Die Lüftungseinrichtung mit zwei Lüftungselementen ist zur ge­trennten wie zur simultanen Regelung von Lufttemperatur und Luft­feuchte in einem Raum geeignet.The ventilation device with two ventilation elements is suitable for separate and simultaneous control of air temperature and humidity in a room.

Besonders vorteilhaft ist eine Weiterbildung der Erfindung, bei der durch eine Kombination von Walzenventilen oder Schiebern die Größe des Öffnungsquerschnitts abhängig von der Feuchte der Innen- und der Temperatur der Außenluft dergestalt geregelt wird, daß die Taupunktstemperatur der Innenluft stets niedriger ist als die nie­drigste Oberflächentemperatur der Raumumschließungsflächen. Da­durch läßt sich die sonst zur Kondenswasser- und bis zur Schimmel­bildung an den den Raum einschließenden Bauteilen führende, beson­ders kritische Situation beherrschen, die auftritt, wenn der Tau­punkt der feuchten Innenluft unterschritten wird.A further development of the invention is particularly advantageous in which the size of the opening cross section is regulated by a combination of roller valves or slides depending on the humidity of the inside and the temperature of the outside air in such a way that the dew point temperature of the inside air is always lower than the lowest surface temperature of the Space enclosing areas. As a result, the particularly critical situation which otherwise leads to the formation of condensation and to the formation of mold on the components enclosing the room can be mastered, which occurs when the dew point of the humid indoor air falls below.

Die in den Figuren (1a, 1b, 1c und 2a, 2b, 2c) dargestellte Lüftungseinrichtung umfaßt zwei Walzenventile 5a bzw. 3b, die in einem gemeinsamen Ge­häuse 3 um ihre voneinander getrennten Achsen, 14a bzw. 14b. drehbar angeordnet sind. Jedes Walzenventil besteht im wesentlichen aus einem Hohlzylinder, 1a bzw. 1b, mit achsparallelen Ausschnitten 2i und 2a, der in einer koaxialen Kammer, 31 bzw. 32, Gehäuses 3 untegebracht ist. Die Kammern für die Unterbringung der Hohlzylinder sind mit Aus­schnitten, Lüftungsschlitzen, 4i bzw. 4a, versehen, die sich zu dem zu lüftenden Raum bzw. zur Außenluft öffnen. Das Gehäuse 3 bildet ein Bauteil, welches in Fensterrahmen oder andere Fassadenbereiche einzubauen ist. Das der Temperaturregulierung dienende Walzenventil 5a wird durch die kraftschlüssig damit verbundene Spiralfeder 11 aus Bimetall nach dem Prinzip eines Metallthermometers abhängig von der Temperatur der Luft betätigt, die durch die Lüf­tungsschlitze 4i und 4a sowie durch die Zylinderausschnit­te 2i und 2a, die dem Walzenventil 5a zugeordnet sind, streicht. Die Intensität des Luftwechsels zwischen Innen­raum und Außenluft hängt von dem Querschnitt der freien Öff­nung ab, die für die durchstreichende Luft durch das Walzen­ventil 5a freigegeben wird; sie ist über die Bimetallfeder 11 von der Lufttemperatur abhängig und durch die sich dek­kenden Teile der achsparallelen Ausschnitte 2i und 2a des Hohlzylinders 1a und der Lüftungsschlitze 4i und 4a, die dem Walzenventil 5a zugeordnet sind, bestimmt.The ventilation device shown in the figures (1a, 1b, 1c and 2a, 2b, 2c) comprises two roller valves 5a and 3b, respectively, in a common housing 3 about their separate axes, 14a and 14b. are rotatably arranged. Each roller valve essentially consists of a hollow cylinder, 1a or 1b, with axially parallel cutouts 2i and 2a, which is accommodated in a coaxial chamber, 31 or 32, housing 3. The chambers for housing the hollow cylinders are provided with cutouts, ventilation slots, 4i and 4a, which open to the room to be ventilated or to the outside air. The housing 3 forms a component which is to be installed in window frames or other facade areas. The roller valve 5a, which serves to regulate the temperature, is actuated by the non-positively connected spiral spring 11 made of bimetal according to the principle of a metal thermometer, depending on the temperature of the air, through the ventilation slots 4i and 4a and through the cylinder cutouts 2i and 2a, which are assigned to the roller valve 5a , strokes. The intensity of the air change between the interior and outside air depends on the cross section of the free opening which is released for the air passing through through the roller valve 5a; it is dependent on the air temperature via the bimetal spring 11 and is determined by the covering parts of the axially parallel cutouts 2i and 2a of the hollow cylinder 1a and the ventilation slots 4i and 4a, which are assigned to the roller valve 5a.

Die Spiralfeder 11 liefert sowohl die Stell- als auch die Rückstellkraft für das Walzenventil 5a. Außer der gezeig­ten Spiralfeder aus Bi-Metall kommen in Rahmen der Erfindung als temperaturabhängige Regulierelemente auch andere Temperatur­federn und Bimetalle sowie hydraulisch arbeitende Temperatur­sensoren mit Flüssigkeits- Gel- oder Wachsfüllung in Be­tracht. Je nach den örtlichen Verhältnissen ist das Walzen­ventil 5a gegen Sonneneinstrahlung und andere nicht unmittel­bar von der Lufttemperatur abhängige Wärmeeinflüsse, die seine Funktion verfälschen würden, zu schützen.The spiral spring 11 provides both the actuating and the restoring force for the roller valve 5a. In addition to the coil spring shown made of bi-metal come within the scope of the invention as temperature-dependent regulating elements also other temperature springs and bimetals as well as hydraulically operating temperature sensors with liquid, gel or wax filling. Depending on the local conditions, the roller valve 5a is to be protected against solar radiation and other heat influences which are not directly dependent on the air temperature and which would distort its function.

Zur Regulierung der Luftfeuchte in dem zu lüftenden Raum ist das Walzenventil 6b bestimmt, welches durch das Regulierele­ment 12 als feuchtigkeitsempfindlichen Sensor betätigt wird. Hierfür kommen im Rahmen der Erfindung insbesondere Fasern oder äquivalente Gebilde in Betracht, die aus Natur- oder Kunsthaar bzw. aus natürlichen oder synthetischen Spinnstof­fen bestehen und/oder mit Beschichtungen versehen sind und die insgesamt hygrophil, desorptions- bzw. absorptionsfähig und langzeitig reversibel sind. In den Fig. 1c und 2c ist ein solcher Sensor als sich mehrfach über die Länge des Ge­häuses 3 erstreckende Faser 12 dargestellt.The roller valve 6b, which is actuated by the regulating element 12 as a moisture-sensitive sensor, is intended for regulating the air humidity in the room to be ventilated. For this purpose, in the context of the invention, in particular fibers or equivalent structures come into consideration which consist of natural or synthetic hair or of natural or synthetic textile materials and / or are provided with coatings and which are overall hygrophilic, capable of desorption or absorption and long-term reversible. 1c and 2c, such a sensor is shown as a fiber 12 extending several times over the length of the housing 3.

Das frei Ende der Faser 12 ist mit einer Feder 15, die der Faser eine dauernde Vorspannung erteilt, am Gehäuse 3 einge­hängt. Über Umlenkrollen 16 ist die Faser 12 sodann mehrmals längs des Gehäuses 3 geführt, um eine vielfache Längenände­rung bei Änderung die Luftfeuchte zu erhalten. Schließlich ist die Faser 12 an einem mit der Achse 14b des Walzenver­tils 5b verbundenen Wickelrad 17 befestigt. Die feuchtig­keitsabhängigen Längenänderungen der Faser 12 bewirken ent­sprechende Drehungen des Walzenventils 5b; dabei liefert die Faser 12 die Stellkraft, während die erforderliche Rückstell­kraft durch eine mit dem Wickelrad 17 verbundene Spiralfeder 13 oder durch ein, hier nicht dargestelltes, gegenläufiges Regulierelement eingeleitet wird. Bei der Anbringung der Lüftungseinrichtung ist darauf zu achten, daß der Feuchtig­keitssensor so plaziert wird, daß er einer konvektiven Strö­mung der Raumluft ausgesetzt wird.The free end of the fiber 12 is attached to the housing 3 by a spring 15 which gives the fiber a permanent prestress. The fiber 12 is then guided several times along the housing 3 via deflection rollers 16 in order to obtain a multiple change in length when the air humidity changes. Finally, the fiber 12 is attached to a winding wheel 17 connected to the axis 14b of the roller valve 5b. The moisture-dependent changes in length of the fiber 12 cause corresponding rotations of the roller valve 5b; the fiber 12 provides the actuating force, while the required restoring force is introduced by a spiral spring 13 connected to the winding wheel 17 or by an opposing regulating element (not shown here). When installing the ventilation device, make sure that the moisture sensor is placed in such a way that it is exposed to a convective flow of the room air.

Die in den Figuren 1d, 1e, 1f und 2a, 2b und 2d dargestellte Aus­führungsform der Erfindung unterscheidet sich von der vorstehend beschriebenen dadurch, daß anstelle des die Luftfeuchte regulier­enden Walzenventiles 5a mit dem feuchtigkeitsempfindlichen Sensor 12 ein Schieber 6a vorgesehen ist, der mit einem Feuchtesensor 19 in Form eines Bandes aus vielen parallelen, hygrophilen Fasern zusammenwirkt. Der Schieber 6a ist in dem Gehäuseteil 3a durch an­geformte Leisten 18 senkrecht geführt. An seinem oberen Ende greift ein dünnes Seil oder ein Draht 20 an, der über eine Umlenk­rolle 16 zu dem einen Ende des mit Querstegen 21 versteiften Faserbandes 19 führt. Das andere Ende des Bandes 19 ist durch einen Draht 22 mit einem am Gehäuse 3 befestigten Halter 23 ver­bunden.The embodiment of the invention shown in FIGS. 1d, 1e, 1f and 2a, 2b and 2d differs from the one described above in that instead of the roller valve 5a regulating the air humidity, a slide 6a is provided with the moisture-sensitive sensor 12, which is equipped with a moisture sensor 19 interacts in the form of a band of many parallel, hygrophilic fibers. The slide 6a is guided vertically in the housing part 3a by molded strips 18. At its upper end, a thin rope or wire 20 engages, which leads via a deflection roller 16 to one end of the sliver 19 stiffened with crossbars 21. The other end of the band 19 is connected by a wire 22 to a holder 23 attached to the housing 3.

Die vorstehend beschriebene Schieberanordnung benötigt zwar grö­ßere Stellkräfte als das Walzenventil. Sie hat aber den Vorteil, daß sie weniger durch starke Windanströmung gestört wird. Der Druck des Windes kann vielmehr den Schieber an die Führung 18 nach innen andrücken und dadurch ein Abdichtung verbessern. Es wird auch keine Rückholfeder benötigt, da der Schieber das Band 19 durch sein Eigengewicht immer straff hält.The slide arrangement described above does require larger actuating forces than the roller valve. But it has the advantage that it is less disturbed by strong winds. Rather, the pressure of the wind can press the slide against the guide 18 inwards and thereby improve a seal. There is also no need for a return spring, since the slider keeps the band 19 taut due to its own weight.

Außer dem beschriebenen Walzenventil und dem Schieber können auch andere Verschlußrogane, wie Klappen oder Gitter sinngemäß als Lüftungselemente Verwendung finden.In addition to the roller valve and the slide described, other closure elements, such as flaps or grilles, can also be used as ventilation elements.

Beim Einsatz der Lüftungseinrichtung zur simultanen Regulierung von Lufttemperatur und -feuchte in einem zu lüftenden Raum sind folgende Fälle in Betracht zu ziehen, aus denen sich die der Lüftungseinrichtung vorzugebende Beziehung ergibt, nach welcher der Gesamtquerschnitt der Öffnungen zwischen Innen- und Außenluft zu regulieren ist.When using the ventilation device for the simultaneous regulation of air temperature and humidity in a room to be ventilated, the following cases should be considered, from which the relationship to be specified for the ventilation device results, according to which the total cross-section of the openings between indoor and outdoor air is to be regulated.

1. Winterfall1. Winter fall

Im Winter herrschen niedrige Außentemperaturen und hohe relative Luftfeuchtigkeiten. Der absolute Wassergehalt, d. h. die Wasser­menge je m³ Luft, ist dagegen sehr klein. Daher kann die auf Raum­temperatur erwärmte Außenluft sehr viel Wasser aufnehmen. Zum Ab­ führen der im Raum produzierten Feuchtigkeit genügt daher ein ge­ringer Luftaustausch. Bei niedrigen Außenlufttemperaturen bleibt daher das temperaturgesteuerte Walzenventil 5a geschlossen, und das feuchtgesteuerte Walzenventil 5b öffnet nur bei Feuchteproduk­tion im Raum. Bei voreingestellter relativer Grenzfeuchte im Raum, z. B. bei 50 %, schließt das Walzenventil 5b vollständig, während es bei relativen Feuchten von z. B. über 80 % vollständig öffnet. Der Übergang dazwischen ist stetig und reversibel. Ein erhöhter Luftaustausch liegt also nur zu Zeiten hoher innerer Feuchtepro­duktionen vor, wodurch die Lüftungseinrichtung mit dem Walzenven­til 5b als Bedarfslüftung funtioniert und somit energiesparend wirkt.In winter there are low outside temperatures and high relative humidity. In contrast, the absolute water content, ie the amount of water per m³ of air, is very small. Therefore, the outside air warmed to room temperature can absorb a lot of water. For Ab Because of the humidity produced in the room, a low air exchange is sufficient. At low outside air temperatures, the temperature-controlled roller valve 5a therefore remains closed, and the moisture-controlled roller valve 5b only opens when the room is producing moisture. With preset relative limit humidity in the room, e.g. B. at 50%, the roller valve 5b closes completely, while it is at a relative humidity of z. B. fully opens over 80%. The transition between them is steady and reversible. An increased air exchange is therefore only present at times of high internal moisture production, as a result of which the ventilation device with the roller valve 5b functions as demand ventilation and thus has an energy-saving effect.

2. Übergangsjahreszeit2nd transition season

In der Übergangsjahreszeit herrschen hohe relative Feuchten bei milden Temperaturen. Der absolute Feuchtegehalt der Außenluft ist sehr groß. Die in den Raum wechselnde Außenluft kann daher nur we­nig Wasserdampf aufnehmen. Bei konstanter Feuchteproduktion ist somit in der Übergangszeit ein größerer Luftaustausch vorzunehmen als in der Winterzeit. Wegen der relativ hohen Außenlufttemperatur wirkt sich dies jedoch nicht stark auf den Wärmeverbrauch und mög­liche verminderte Energieeinsparung aus. Bei optimaler Auslegung des Walzenventils 5b reicht der Luftaus­tausch über dieses Element alleine nicht mehr zum Abbau der Feuch­tigkeit im Raum aus. Daher wird mit ansteigenden Außenlufttempera­turen das Walzenventil 5a selbsttätig geöffnet. Der erforderliche Luftaustausch ist somit freigegeben. Die Lüftungseinrichtung gemäß der Erfindung zeichnet sich jetzt als Einrichtung zur Grund- und Bedarfslüftung aus.In the transition season, there are high relative humidities at mild temperatures. The absolute moisture content of the outside air is very large. The outside air that changes into the room can therefore only absorb a little water vapor. With constant moisture production, a larger air exchange is to be carried out in the transitional period than in winter. However, due to the relatively high outside air temperature, this does not have a major impact on heat consumption and possible reduced energy savings. If the roller valve 5b is optimally designed, the air exchange via this element alone is no longer sufficient to break down the moisture in the room. Therefore, the roller valve 5a is automatically opened with rising outside air temperatures. The required air exchange is thus released. The ventilation device according to the invention stands out now as a device for basic and on-demand ventilation.

3. Sommerfall3rd summer fall

Bei hohen Außenlufttemperaturen ist das Walzenventil 5a vollständig geöffnet. Das Walzenventil 5b unterstützt den Luftaustausch nur bei hohen inneren Feuchtebelastungen. Durch den erhöhten Grundlüftungsstrom werden Überhitzungs­effekte bei starker Sonneneinstrahlung vermindert, wodurch die Lüftungseinrichtung gemäß der Erfindung zu einem be­haglicheren Raumklima führt.At high outside air temperatures, the roller valve 5a is fully open. The roller valve 5b supports the air exchange only when there are high internal moisture loads. As a result of the increased basic ventilation flow, overheating effects in strong sunlight are reduced, as a result of which the ventilation device according to the invention leads to a more comfortable room climate.
