Description
Die Erfindung betrifft ein Verfahren zur Klimatisierung eines Raumes, bei dem Außenluft durch eine nicht mit einem Klimagerät verbundene Außenluftöffnung in den Raum strömen kann und Raumluft mittels des mindestens einen Klimageräts konditionierbar ist.The invention relates to a method for air conditioning a room in which outside air can flow through a not connected to an air conditioner outside air opening into the room and room air is conditioned by means of at least one air conditioner.
Ein Verfahren der vorstehend genannten Art wird dann durchgeführt, wenn ein Raum eines Gebäudes oder dergleichen mittels eines Klimageräts klimatisiert wird und gleichzeitig ein Fenster des Raumes offen steht. Das offen stehende Fenster kann -je nach Außenluft-temperatur- dazu führen, dass -insbesondere im Sommer- die Raumlufttemperatur ansteigt. Befindet sich im Raum ein Temperatursensor des Klimageräts, so wird die Temperaturerhöhung registriert und vom Klimagerät der Versuch unternommen, die Raumlufttemperatur wieder zu senken. Entsprechend umgekehrte Verhältnisse sind insbesondere im Winter zu erwarten, d.h., das offen stehende Fenster führt zu einer starken Raumluftabkühlung, die das Klimagerät zu kompensieren versucht. Insgesamt ist festzustellen, dass aufgrund des offen stehenden Fensters kein ordnungsgemäßer Klimatisierungsbetrieb möglich ist.A method of the type mentioned above is carried out when a room of a building or the like is conditioned by means of an air conditioner and at the same time a window of the room is open. Depending on the outside air temperature, the open window may cause the room air temperature to rise, especially in summer. If a temperature sensor of the air conditioner is located in the room, the temperature increase is registered and the air conditioner attempts to lower the room air temperature again. Correspondingly reverse conditions are to be expected especially in winter, that is, the open window leads to a strong room air cooling, which tries to compensate for the air conditioner. Overall, it should be noted that due to the open window no proper air conditioning operation is possible.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Klimatisierung eines Raumes anzugeben, dass einen hinreichenden Frischluftanteil in einem Raum bei gleichzeitiger optimalen Klimatisierung des Raumes gewährteistet.The invention has for its object to provide a method for air conditioning of a room that gewährteistette a sufficient proportion of fresh air in a room while optimizing the air conditioning of the room.
Diese Aufgabe wird gelöst durch ein Verfahren laut Anspruch 1, insbesondere durch die kombinierte Steuerung oder Regelung mindestens folgender Größen: Außenluft-Öffnungs-querschnitt, und Volumenstrom eines Heiz- und/oder Kühlmittels durch mindestens einen Wärmetauscher des Klimageräts. Die vorstehend genannten Größen werden durch die kombinierte, also unter sich abgestimmte und die jeweils vorliegende Situation berücksichtigende Steuerung oder Regelung fortlaufend oder in kurzen Zeitabständen so eingestellt, dass sich optimale Klimatisierungsverhältnisse im Raum ergeben. Ein entsprechend groß eingestellter Außenluft-Öffnungsquerschnitt stellt den Zustrom von frischer Luft sicher. Hierbei wird vorzugsweise auch die Außenlufttemperatur berücksichtigt, um im Raum die gewünschte Raumlufttemperatur zu erhalten oder beizubehalten. Die Steuerung oder Regelung des Luft-Volumenstromes des Klimagerätes führt zu einer entsprechend großen Volumenstrombehandlung der Raumluft, die im Umluftverfahren konditioniert wird. Da das Klimagerät einen Wärmetauscher aufweist, der durch einen entsprechend eingestellten Volumenstrom eines Heiz- oder Kühlmittels den Luft-Volumenstrom der Raumluft im gewünschten Maße erwärmen oder abkühlen kann, wird die gewünschte Raumtemperatur eingestellt. Im Falle einer so genannten "Stillen Kühlung" erfolgt die kombinierte Steuerung oder Regelung des Außenluft-Öffnungsquerschnitts und des Volumenstroms eines Heiz- und/oder Kühlmittels, insbesondere Kühlmittels, durch mindestens einen Wärmetauscher des Klimageräts. Die kombinierte Steuerung oder Regelung stellt stets sicher, dass beispielsweise im Falle sehr niedriger Außentemperaturen der Außenluft-Öffnungsquerschnitt möglichst klein gehalten wird, um ein unangenehmes Raumklima zu vermeiden. Dennoch wird durch die Außenluftzufuhr ein hinreichender Sauerstoffgehalt der Raumluft garantiert. Insbesondere kann auch vorgesehen sein, dass im vorstehend erwähnten Falle der Querschnitt der Außenluft-Öffnung nicht permanent offen gehalten, sondern nur stoßweise zum Zwecke einer sogenannten Stoßlüftung aufgefahren und anschließend die Außenluft-Öffnung, insbesondere ein Fenster oder dergleichen, wieder verschlossen wird.This object is achieved by a method according to
Ferner ist von Vorteil, wenn als Klimagerät ein Ventilatorkonvektor verwendet wird. Der Ventilatorkonvektor weist als wesentliche Komponenten einen Ventilator zur Luftförderung und den bereits erwähnten Wärmetauscher auf, dessen Heiz- oder Kühlmittel im Volumenstrom verändert werden kann. Wird eine Drehzahlbeeinflussung des Ventilators vorgenommen, so kann hierdurch der vorstehend erwähnte Luft-Volumenstrom eingestellt werden.It is also advantageous if a fan coil is used as air conditioner. The fan coil unit has as essential components a fan for conveying air and the already mentioned heat exchanger whose heating or cooling medium can be varied in the volume flow. If a speed influence of the fan is made, then the above-mentioned air volume flow can be adjusted thereby.
Zusätzlich oder alternativ ist es auch möglich, wenn als Klimagerät ein Induktionsgerät verwendet wird. Die Induktionswirkung wird dadurch erzielt, dass mittels einer Luftfördereinrichtung, beispielsweise eines Ventilators, Raumluft angesaugt und Luftdüsen zugeführt werden. Die Luftdüsen erzeugen in einem Mischraum einen Unterdruck, durch den weitere Raumluft angesaugt wird, die den erwähnten Wärmetauscher passiert. Der Volumenstrom eines Heiz- oder Kühlmittels des Wärmetauschers lässt sich entsprechend mittels der kombinierten Steuerung oder Regelung beeinflussen.Additionally or alternatively, it is also possible if an induction device is used as an air conditioner. The induction effect is achieved by sucking in air and air nozzles by means of an air conveyor, such as a fan. The air nozzles generate in a mixing chamber a negative pressure, is sucked through the more room air that passes through the mentioned heat exchanger. The volume flow of a heating or cooling medium of the heat exchanger can be influenced accordingly by means of the combined control or regulation.
Nach einer Weiterbildung ist es möglich, dass nicht nur durch den Außenluft-Öffnungsquerschnitt Außenluft in den Raum gelangen kann, sondern dass das Klimagerät, insbesondere der Ventilatorkonvektor und/oder das Induktionsgerät auch Außenluft in den Raum einbringt. Im Falle des Ventilatorkonvektors kann dessen Ventilator beispielsweise Raumluft, Außenluft oder sowohl Raumluft und Außenluft fördern und dabei den geförderten Luftstrom mittels des Wärmetauschers konditionieren. Im Falle des Induktionsgerätes ist es möglich, den Luftdüsen Raumluft oder Außenluft oder sowohl Raumluft und Außenluft zuzuführen.According to a development, it is possible that outside air can enter the room not only through the outside air opening cross section, but that the air conditioner, in particular the fan coil and / or the induction device also introduces outside air into the room. In the case of the fan coil, the fan may, for example, convey room air, outside air or both room air and outside air and thereby condition the conveyed air flow by means of the heat exchanger. In the case of the induction device is it is possible to supply the air nozzles with room air or outside air, or with both room air and outside air.
Außenluft kann dem Raum über den bereits erwähnten Außenluft-Öffnungsquerschnitt also durch die Außenluftöffnung und/oder einen zusätzlichen Außenluftzugang zugeführt werden. Durch die Außenluftöffnung gelangt die Außenluft stets direkt in den Raum, ohne dass diese das Klimagerät passiert. Zusätzlich oder alternativ ist es möglich, durch einen Außenluftzugang dem Klimagerät, das als Ventilatorkonvektor und/oder als Induktionsgerät ausgebildet sein kann, Außenluft zuzuführen. Zusätzlich oder alternativ besteht überdies die Möglichkeit, dass ein bestimmter Anteil der durch die Außenluftöffnung in den Raum strömende Luft vom Klimagerät angesaugt und konditioniert wird. Ein anderer Anteil der Außenluft verteilt sich ohne das Passieren des Klimagerätes im Raum.Outside air can be supplied to the room via the already mentioned outside air opening cross-section through the outside air opening and / or an additional outside air access. Through the outside air opening the outside air always gets directly into the room, without them passing the air conditioner. Additionally or alternatively, it is possible, by an outside air access to the air conditioner, which may be configured as a fan coil and / or induction device to supply outside air. Additionally or alternatively, there is also the possibility that a certain proportion of the air flowing through the outside air opening into the room is sucked in and conditioned by the air conditioning unit. Another part of the outside air is distributed without passing through the air conditioner in the room.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass das Klimagerät, der Ventilatorkonvektor und/oder das Induktionsgerät mit zentral aufbereiteter Primärluft versorgt wird. Bei der zentral aufbereiteten Primärluft handelt es sich vorzugsweise um Außenluft, die im Hinblick auf ihre Parameter, insbesondere Temperatur und/oder Luftfeuchtigkeit, zentral aufbereitet und dann über entsprechende Luftkanäle dem Klimagerät, dem Ventilatorkonvektor und/oder dem Induktionsgerät zugeführt wird. Zusätzlich oder alternativ ist es auch möglich, dass zumindest ein Anteil der zentral aufbereiteten Primärluft ohne das Passieren des Klimageräts in den zu klimatisierenden Raum gelangt. In einem solchen Falle wird die kombinierte Steuerung/Regelung den Volumenstrom dieser zentral aufbereiteten primären Luft mit kontrollieren.According to a development of the invention it is provided that the air conditioner, the fan coil and / or the induction unit is supplied with centrally processed primary air. The centrally processed primary air is preferably outside air, which is processed centrally with regard to its parameters, in particular temperature and / or air humidity, and then supplied via appropriate air ducts to the air conditioning unit, the fan coil unit and / or the induction unit. Additionally or alternatively, it is also possible that at least a portion of the centrally processed primary air passes without passing through the air conditioner in the room to be air-conditioned. In such a case, the combined control will control the flow rate of this centrally treated primary air.
Insbesondere kann vorgesehen sein, dass der Raum im Wesentlichen mittels Quelllüftung klimatisiert wird.In particular, it can be provided that the space is essentially conditioned by means of displacement ventilation.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Raum im Wesentlichen mittels Mischquelllüftung klimatisiert wird.According to a development of the invention, it is provided that the space is air conditioned essentially by means of mixed source ventilation.
Die Erfindung betrifft ferner eine Anordnung zur Klimatisierung eines Raumes, bei der Außenluft durch eine nicht mit einem Klimagerät verbundene Außenluftöffnung in den Raum strömen kann und Raumluft mittels des mindestens einen Klimageräts konditionierbar ist, wobei eine Steuer- und/oder Regeleinrichtung für die kombinierte Steuerung und/oder Regelung mindestens folgender Größen vorgesehen ist: Außenluft-Öffnungsquerschnitt und Volumenstrom eines Heiz- und/oder Kühlmittels durch mindestens einen Wärmetauscher des Klimageräts.The invention further relates to an arrangement for the air conditioning of a room in which outside air can flow through a not connected to an air conditioner outside air opening into the room and room air is conditioned by means of at least one air conditioner, wherein a control and / or regulating device for the combined control and / or regulation of at least the following sizes is provided: outside air opening cross-section and volume flow of a heating and / or coolant through at least one heat exchanger of the air conditioner.
Bei dem Klimagerät kann es sich insbesondere um einen Ventilatorkonvektor und/oder ein Induktionsgerät handeln. Der Ventilatorkonvektor und/oder das Induktionsgerät können zentrale oder dezentrale Geräte sein. Handelt es sich um zentrale Geräte, so sind sie in dem zu klimatisierenden Raum zugeordnet, werden jedoch von zentral aufbereiteter Luft versorgt. Die zentralen Geräte im Raum dienen der Nachbehandlung der aufbereiteten Luft - insbesondere Heizen oder Kühlen - oder sie mischen Raumluft bei, bevor die Nachbehandlung erfolgt. Bei dezentralen Geräten handelt es sich um im Raum aufgestellte Geräte. Diese Geräte sind insbesondere auf das Luftvolumen und die sonstigen Anforderungen (Temperatur und/oder Luftfeuchtigkeit) des zu klimatisierenden Raumes ausgelegt.The air conditioner may in particular be a fan coil and / or an induction unit. The fan coil and / or the induction unit may be central or remote units. If they are central units, they are allocated in the room to be air-conditioned, but are supplied with centrally treated air. The central devices in the room are used for the aftertreatment of the treated air - in particular heating or cooling - or they mix in room air before the aftertreatment takes place. Decentralized devices are devices installed in the room. These devices are designed in particular for the volume of air and other requirements (temperature and / or humidity) of the room to be air conditioned.
Die Außenluftöffnung wird von dem Querschnitt eines dem Raum zugeordneten Fensters, einer Tür oder dergleichen gebildet. Mittels der kombinierten Steuerung oder Regelung wird der Außenluft-Öffnungsquerschnitt entsprechend eingestellt. Handelt es sich bei der Außenluftöffnung beispielsweise um den Öffnungsquerschnitt eines Fensters, so lässt sich die Fensterflügelstellung mittels einer geeigneten Antriebseinrichtung vorzugsweise stufenlos oder in Stufen verändern, um den erforderlichen Öffnungsquerschnitt zum Einströmen von Außenluft bereitzustellen. Die Antriebseinrichtung wird von der kombinierten Steuerung oder Regelung kontrolliert, so dass eine steuer- oder regelbare Antriebseinrichtung vorliegt. Insbesondere kann die Antriebseinrichtung einen Elektromotor zur Einstellung des Außenluft-Öffnungsquerschnitts aufweisen. Da aus Sicherheitsgründen die Außenluftöffnung zu verriegeln ist, wenn sich zum Beispiel keine Personen in dem Raum aufhalten oder nachts das Gebäude nicht zugänglich sein soll, kann die erwähnte Antriebseinrichtung oder eine separate Einrichtung eine Verriegelungseinrichtung des Fensters, der Tür oder dergleichen zum Entriegeln oder Verriegeln des Fensterflügels, des Türflügels oder dergleichen betätigen. Für eine Öffnung zum Einströmen von Außenluft ist es daher dann erforderlich, zunächst eine Entriegelung vorzunehmen und dann - beispielsweise im Falle eines Fensters- den Fensterflügel entsprechend weit zu öffnen. Bei einer Verriegelung ist zunächst vorgesehen, dass der Außenluft-Öffnungsquerschnitt geschlossen und dann das Fenster, die Tür oder dergleichen verriegelt wird. Dieses Entriegeln oder Verriegeln kann im Falle eines Fensters beispielsweise mittels eines Treibstangensystems erfolgen, dass von der Antriebseinrichtung oder der separaten Einrichtung angetrieben wird. Manuelle Eingriffe sind daher nicht erforderlich.The outside air opening is formed by the cross section of a window associated with the room, a door or the like. through the combined control or regulation of the outside air opening cross section is adjusted accordingly. If the outside air opening is, for example, the opening cross section of a window, then the window sash position can preferably be varied steplessly or in steps by means of a suitable drive device, in order to provide the required opening cross section for the inflow of outside air. The drive device is controlled by the combined control or regulation, so that a controllable or controllable drive device is present. In particular, the drive device may have an electric motor for adjusting the outside air opening cross section. Since, for safety reasons, the outside air opening is to be locked, for example if there are no persons in the room or at night the building should not be accessible, the mentioned drive device or a separate device may include a locking device of the window, the door or the like for unlocking or locking the Press sash, the door leaf or the like. For an opening for the influx of outside air, it is therefore necessary to first perform an unlocking and then - for example, in the case of a window - to open the window sash accordingly. With a lock, it is initially provided that the outside air opening cross section is closed and then the window, the door or the like is locked. This unlocking or locking can be done in the case of a window, for example by means of a drive rod system that is driven by the drive device or the separate device. Manual intervention is therefore not required.
Insbesondere kann die Steuer- oder Regeleinrichtung der Antriebseinrichtung zugeordnet sein. Hierzu kann die Steuer- oder Regeleinrichtung und die Antriebseinrichtung in einem gemeinsamen Gehäuse untergebracht werden. Diese Kombination aus Steuer- oder Regeleinrichtung und der Antriebseinrichtung befindet sich insbesondere am Fenster, der Tür oder dergleichen, vorzugsweise am Fensterflügel, am Türflügel oder dergleichen. Im Fensterantriebsgehäuse können nicht nur Antrieb und Steuerung beziehungsweise Regelung untergebracht sein, sondern auch Sensoren. Diese Sensoren sind insbesondere Lufttemperaturfühler und/oder Luftgeschwindigkeitsmesser. Nach den genannten Parametern Lufttemperatur und Luftgeschwindigkeit richtet sich der Außenluft-Öffnungsquerschnitt, die Ansteuerung des Ventilators und damit der Luft-Volumenstrom des Klimageräts, sowie der Öffnungsquerschnitt der Ventile, also der Volumenstrom des Heiz- und/oder Kühlmittels durch den mindestens einen Wärmetauscher des Klimageräts. Befindet sich die erwähnte Kombination beispielsweise am Fensterflügel, so ist dadurch sichergestellt, dass das Treibstangensystem des Fensterflügels zum Ver- oder Entriegeln betätigt werden kann.In particular, the control or regulating device may be assigned to the drive device. For this purpose, the control or regulating device and the drive means are housed in a common housing. This combination of control or regulating device and the drive device is located in particular on the window, the door or the like, preferably on the window sash, on the door leaf or the like. In the window drive housing not only drive and control or regulation can be accommodated, but also sensors. These sensors are in particular air temperature sensors and / or air speed meters. After the above parameters air temperature and air speed, the outside air opening cross section, the control of the fan and thus the air volume flow of the air conditioner, as well as the opening cross section of the valves, so the volume flow of the heating and / or cooling means by the at least one heat exchanger of the air conditioner , The mentioned combination is, for example, on the window sash, this ensures that the drive rod system of the sash can be operated for locking or unlocking.
Der Ventilatorkonvektor kann insbesondere als Boden-, Brüstungs- und/oder Deckengerät ausgebildet sein.The fan coil can be designed in particular as floor, parapet and / or ceiling unit.
Schließlich ist vorgesehen, dass das Induktionsgerät ein Boden-, Brüstungs- und/oder Deckengerät ist.Finally, it is provided that the induction device is a floor, parapet and / or ceiling device.

Der Raum 1 weist ferner einen Boden 9 und eine Decke 10 auf. In die Decke 10 ist ein Klimagerät 11 fluchtend eingelassen. Das Klimagerät 11 befindet sich unmittelbar angrenzend an die Fassadenwand 2 und ist als Ventilatorkonvektor 12 ausgebildet. Aufgrund seiner Anordnung in der Decke 10 bildet der Ventilatorkonvektor 12 ein Deckengerät 13.The
Der Ventilatorkonvektor 12 besitzt im Bereich nahe des Fensters 4 eine Lufteintrittsöffnung 14 und -weiter entfernt vom Fenster 4- eine Luftaustrittsöffnung 15. Zwischen Lufteintrittsöffnung 14 und Luftaustrittsöffnung 15 ist -im Innern des Ventilatorkonvektors 12- ein Ventilator 16 und -stromabwärts des Ventilators 16- ein Wärmetauscher 17 angeordnet. Die Drehzahl des Ventilators 16 ist einstellbar, so dass mit ihm ein entsprechender Luft-Volumenstrom 18 gefördert wird. Dieser Luft-Volumenstrom 18 tritt durch die Lufteintrittsöffnung 14 in den Ventilatorkonvektor 12 ein und durch die Luftaustrittsöffnung 15 wieder in den Raum 1 aus.The

Am Fensterflügel 6 des Fensters 4 ist eine Antriebseinrichtung 21 für die Betätigung des Fensterflügels 6 angebracht. Hierzu ist die Antriebseinrichtung 21 über eine Kraftwirkstrecke 22 mit dem Blendrahmen 5 verbunden. Die Antriebseinrichtung 21 wirkt auf die Kraftwirkstrecke 22 und verbringt dadurch den Fensterflügel 6 in die jeweils gewünschte Öffnungsstellung, so dass sich ein dementsprechender Außenluft-Öffnungsquerschnitt 8 einstellt. Ferner besitzt die Antriebseinrichtung 21 eine Verriegelungseinrichtung 23, die mit einem nicht dargestellten Treibstangensystem des Fensters 4 zusammenwirkt. Auf diese Art und Weise ist sichergestellt, dass bei einer Betätigung der Antriebseinrichtung 21 zunächst mittels der Verriegelungseinrichtung 23 eine Entriegelung des Fensterflügels 6 erfolgt, bevor dieser in Offenstellung verbracht wird. Wird der Fensterflügel 6 verschlossen, so sorgt die Verriegelungseinrichtung 23 der Antriebseinrichtung 21 dafür, dass nach dem Verschließen des Fensterflügels 6 eine Verriegelung durchgeführt wird.On the
Im Gehäuse 24 der Antriebseinrichtung 21 befindet sich ferner eine Steuer- oder Regeleinrichtung 25, die -in Abhängigkeit bestimmter Parameter- die Klimatisierung des Raumes 1 steuert oder regelt. Hierauf wird im Nachstehenden noch näher eingegangen. Alternativ kann die Steuer- oder Regeleinrichtung auch an einer anderen Stelle des Raumes 1 untergebracht sein.In the

Die Steuer- oder Regeleinrichtung 25 steuert oder regelt den vorstehend erwähnten Klimatisierungsprozess, indem sie entsprechend den im Raum 1 gewünschten Klimatisierungsanforderungen die Antriebseinrichtung 21 ansteuert, so dass sich der für die vorliegende Lüftungsaufgabe sinnvolle Außenluft-Öffnungsquerschnitt 8 einstellt.The
Ferner steuert sie den Ventilator 16 entsprechend an, so dass sich der für diese Lüftungsaufgabe sinnvolle Luft-Volumenstrom 18 einstellt. Ferner sorgt die Steuer- oder Regeleinrichtung 25 durch entsprechendes Ansteuern der Volumenstrom-Einstelleinrichtung 20 dafür, dass ein entsprechender Volumenstrom des Kühlmittels 27 durch den Wärmetauscher 17 strömt. Alle genannten Steuer- oder Regelungsaufgaben sind aufeinander abgestimmt, so dass eine kombinierte Steuerung beziehungsweise Regelung vorliegt, die zu optimalen Klimatisierungsbedingungen des Raumes 1 führt.

Vorzugsweise ist die Anordnung derart getroffen, dass das Gehäuse 24 auf dem Fensterflügel 6 montiert und dass der Grundkörper 49 am Blendrahmen 5 des Fensters 4 befestigt wird. Die Steuer- oder Regeleinrichtung 25 gibt bei Bedarf entsprechende Signale an den Antrieb der Antriebseinrichtung 21, so dass der Exzenter 47 betätigt und eine Kraft über die Gelenkstange 48 auf den Grundkörper 49 übertragen wird, wodurch es zu einem Öffnen beziehungsweise Schließen oder zu einer Verstellung des Außenluft-Öffnungsquerschnitts 8 kommt. Die Anordnung ist vorzugsweise derart getroffen, dass aus der Unterseite des Gehäuses 24 ein Vierkant herausragt, der mit dem Treibstangensystem (nicht dargestellt) des Fensters 4 zusammenwirkt und eine Verriegelung beziehungsweise Entriegelung des Fensters 4 vornehmen kann. Im Betrieb wird daher zunächst das Fenster entriegelt und dann in eine entsprechende Offenstellung gefahren. Entsprechend wird bei einem Schließen des Fensters zunächst der Fensterflügel 6 in Schließstellung verbracht und dann die Verriegelung mittels des Treibstangensystems vorgenommen.Preferably, the arrangement is such that the
Insgesamt ist anzumerken, dass neben der Aufstellung eines oder mehrerer Klimageräte, als Ventilatorkonvektor(en) und/oder als Induktionsgerät(e), in einem zu klimatisierenden Raum zusätzlich auch noch die Aufstellung eines Induktionsgerätes, insbesondere eines Bodeninduktionsgerätes vorstellbar ist, dass für eine Grundklimatisierung mit Frischluft und/oder Umluft zuständig ist und dass darüber hinaus die Anordnung in dem Raum untergebracht ist, wie sie sich aus den Ausführungsbeispielen der
Zusätzlich zu den erwähnten Steuerungs- oder Regelungsmaßhahmen können bei dem Gegenstand der Erfindung weitere Sensoren vorgesehen sein, die beispielsweise bestimmte Bereiche des Raumes hinsichtlich der Temperatur erfassen. Ferner ist es möglich, zusätzlich oder alternativ den Winddruck beziehungsweise die Windgeschwindigkeit zu sensieren und bei der Steuerung beziehungsweise Regelung zu berücksichtigen.In addition to the aforementioned control measures, the invention may include further sensors which detect, for example, certain areas of the room in terms of temperature. Furthermore, it is possible to additionally or alternatively sense the wind pressure or the wind speed and to take it into account in the control or regulation.
In den mit Figuren versehenen Ausführungsbeispielen sind als Fenster Kippfenster eingesetzt. Die Erfindung ist selbstverständlich auch -bei entsprechender Ausbildung des Fensterantriebs- bei Drehfenstern anwendbar. Die Drehachse liegt vorzugsweise in einem der beiden Seitenbereiche des Fensterflügels. Alternativ ist es auch möglich, die vertikal verlaufende Drehachse etwa in der Mitte der Breitenerstreckung des Fensters vorzusehen, so dass rechts und links von der Drehachse jeweils bei einer Öffnungsbewegung des Fensters ein Außenluft-Öffnungsquerschnitt geschaffen wird.In the embodiments provided with figures tilting windows are used as windows. Of course, the invention can also be applied to rotary windows if the window drive is designed accordingly. The axis of rotation is preferably in one of the two side regions of the window sash. Alternatively, it is also possible to provide the vertical axis of rotation approximately in the middle of the width of the window, so that an outside air opening cross section is created to the right and left of the axis of rotation in each case during an opening movement of the window.
Die erwähnten Quelllüftungen sorgen im Sommer für eine hohe Temperaturschichtung, da niedrige Luftgeschwindigkeiten vorliegen. Die gekühlte Luft bleibt am Boden und strömt nicht über das Fenster ab. Es ergibt sich ein geringer Energieverlust. Im Winter weist die Quelllüftung den Vorteil auf, dass im Heizbetrieb ein Kaltluftabfall an der Fensterscheibe verhindert wird. Wärmeverluste durch Warmluft, die über das Fenster entweicht, können als gering hingenommen werden.The mentioned source vents ensure a high temperature stratification in the summer, since low air velocities are present. The cooled air stays on the floor and does not flow over the window. It results in a low energy loss. In winter, the source ventilation has the advantage that in the heating mode, a cold air drop is prevented on the window pane. Heat loss from hot air escaping through the window can be considered low.
Die erwähnte Misch-Quelllüftung führt im Sommer zu einer geringeren Temperaturschichtung gegenüber einer reinen Quelllüftung, da eine Raumluftbeimischung erfolgt. Eine Kurzschlussgefahr kann durch entsprechende Lenkung der Luft verhindert werden. Im Winter wird bei der Misch-Quelllüftung im Heizbetrieb ein Kaltluftabfall an der Fensterscheibe verhindert. Es kann bevorzugt eine Abschirmung durch Fächer erfolgen, die wirkungsvoller als bei der Quelllüftung ist. Die Wärmeverluste durch über das Fenster entweichende Warmluft können sehr gering gehalten werden, so dass sie nicht störend in Erscheinung treten. Bei den Ausführungsbeispielen der
Bei dem erfindungsgemäßen Steuer- oder Regelungsverfahren kann insbesondere als weiterer, von der kombinierten Steuerung zu berücksichtigender Parameter die Außentemperatur Berücksichtigung finden. Ferner ist es zusätzlich oder alternativ möglich, die Innentemperatur, insbesondere im Fußbodenbereich, zu sensieren, um niedrige Bodentemperaturen zu vermeiden.In the control or regulating method according to the invention, in particular as another, to be taken into account by the combined control Parameters that take into account the outside temperature. Furthermore, it is additionally or alternatively possible to sense the internal temperature, in particular in the floor area, in order to avoid low floor temperatures.
Bezüglich der Steuerung und/oder Regelung sind folgende bevorzugte Ausführungen denkbar: Ziel der Fensterlüftung ist es, den Frischluftbedarf des Raumes zu decken. Dabei wird kostengünstige Frischluft aufgrund der Fensterlüftung verwendet, die zur Verbesserung des Raumklimas nachbehandelt wird. Als Steuerungs- beziehungsweise Regelungsbeispiele ist insbesondere Folgendes vorgesehen: Der Frischluftbedarf hängt von der Personenzahl im Raum ab und lässt sich dementsprechend vorgeben. Die Steuerung und/oder Regelung stellt dann den geeigneten Außenluft-Öffnungsquerschnitt ein. Dabei werden die Druckverhältnisse an der Fassade des die Außenluftöffnung aufweisenden Raumes und/oder die Druckverhältnisse an der Außenluftöffnung berücksichtigt. Liegt ein hoher Fassadendruck vor, so wird eine kleine Öffnung eingestellt. Dabei bleibt der Frischluftbedarf konstant. Bei geringem Fassadendruck wird eine große Außenluftöffnung eingestellt, wobei ebenfalls der Frischluftbedarf konstant gehalten wird. Bei Sog oder Regen wird die Außenluftöffnung geschlossen und gegebenenfalls eine andere Außenluftöffnung, insbesondere ein anderes Fenster, automatisch geöffnet, bei dem Überdruck besteht. Dieses Vorgehen kann natürlich nur dann durchgeführt werden, wenn die erwähnten Verhältnisse vorliegen.With regard to the control and / or regulation, the following preferred embodiments are conceivable: The aim of the window ventilation is to cover the fresh air requirement of the room. In this case, inexpensive fresh air is used due to the window ventilation, which is aftertreated to improve the indoor climate. As control or regulation examples in particular the following is provided: The fresh air requirement depends on the number of people in the room and can be pretended accordingly. The control and / or regulation then sets the appropriate outside air opening area. In this case, the pressure conditions on the facade of the outside air opening having space and / or the pressure conditions at the outside air opening are taken into account. If there is a high facade pressure, a small opening is set. The fresh air requirement remains constant. At low facade pressure, a large outside air opening is set, while also the fresh air requirement is kept constant. In the case of suction or rain, the outside air opening is closed and optionally another outside air opening, in particular another window, is automatically opened, in which there is overpressure. Of course, this procedure can only be carried out if the conditions mentioned are present.
Je nach Temperatur der Frischluft (Außenluft) werden Ventilator des Klimageräts und Volumenstrom des Kühl- und/oder Heizmittel des Klimageräts durch entsprechende Ventileinstellung oder - bei zentralen, mit Luft versorgten Klimageräten - die Klappen und Volumenstromregler für die Luft sowie die Ventile für das Kühl- und/oder Heizmittel angesteuert. Denkbar ist auch ein 4-Leitersystem, das sowohl heizen und kühlen kann, und bei dem jeweils eine Ansteuerung beziehungsweise Regelung der entsprechenden Ventile erfolgt.Depending on the temperature of the fresh air (outside air) fan of the air conditioner and volume flow of the cooling and / or heating means of the air conditioner by appropriate valve setting or - in central, air-supplied air conditioners - the flaps and flow controllers controlled for the air and the valves for the cooling and / or heating means. Also conceivable is a 4-conductor system, which can both heat and cool, and in each of which a control or regulation of the corresponding valves takes place.
Liegt eine hohe Temperatur und eine hohe Geschwindigkeit der Frischluft (Außenluft) vor, bedarf es einer relativ hohen Drehzahl des Ventilators des Klimageräts und einer offenen beziehungsweise weit geöffneten Stellung der Ventile für das Kühlmittel. Bei hoher Außenlufttemperatur und geringer Geschwindigkeit dieser Frischluft bedarf es einer geringen Drehzahl des Ventilators und einer offenen Stellung der Ventile des Kühlmittels. Entsprechendes gilt im Winter beim Heizfall.If a high temperature and a high speed of the fresh air (outside air) is present, it requires a relatively high speed of the fan of the air conditioner and an open or wide open position of the valves for the coolant. At high outside air temperature and low speed of this fresh air, it requires a low speed of the fan and an open position of the valves of the coolant. The same applies in winter when heating.
Alle Lüftungsvarianten richten sich grundsätzlich nach dem Komfort und der Wirtschaftlichkeit. So könnte auch bei hoher Temperatur und geringer Geschwindigkeit der Frischluft die Drehzahl erhöht und die Ventile des Kühlmittels in Richtung Schließstellung verbracht werden. Die Steuerung oder Regelung kann ein Kennfeld aufweisen, in dem ein Soll-Wert festgelegt wird. Durch die von den Sensoren erfolgte Messung von Temperatur und/oder Druck und/oder Geschwindigkeit der Luft am Fenster sowie der Raumtemperatur wird ein Ist-Wert bestimmt. Nun werden Fensterantrieb, Ventile des oder der Wärmetauscher und Drehzahl des oder der Ventilatoren angesteuert, um auf den notwendigen Soll-Wert zu kommen.All ventilation variants are always based on comfort and economy. Thus, even at high temperature and low speed of the fresh air, the speed could be increased and the valves of the coolant can be moved in the direction of the closed position. The controller or controller may include a map in which a desired value is set. By measuring the temperature and / or pressure and / or velocity of the air at the window and the room temperature, an actual value is determined. Now window drive, valves or the heat exchanger and speed of the fan or fans are controlled in order to come to the required target value.
Da in den meisten Anwendungsfällen gekühlt werden muss, ist eine sehr einfache Ausführungsform der Steuerung und/oder Regelung dadurch möglich, dass Sensoren verwendet werden, die am Gehäuse des Antriebs des Fensters oder dergleichen platziert sind, die die Temperaturdifferenz am Fenster oder dergleichen zwischen innen und außen messen. Das Fenster, die Tür oder dergleichen, also die Außenluftöffnung, schließt oder bleibt geschlossen, wenn die Raumtemperatur kühler als die Außentemperatur ist. Das Fenster oder dergleichen öffnet, wenn die Außentemperatur kühler als die Raumtemperatur ist.Since it is necessary to cool in most applications, a very simple embodiment of the control and / or regulation is possible by using sensors which are placed on the housing of the drive of the window or the like, which the Measure the temperature difference at the window or the like between inside and outside. The window, the door or the like, ie the outside air opening, closes or remains closed when the room temperature is cooler than the outside temperature. The window or the like opens when the outside temperature is cooler than the room temperature.
Ferner richtet sich die Ventilatordrehzahl des Klimageräts beziehungsweise der Klimageräte vorzugsweise auch nach der Lüftungsmethode, das/die in Quelllüftung oder als Mischquelllüftung betrieben werden kann/können. Ferner besteht eine Abhängigkeit nach der Platzierung des oder der Klimageräte, insbesondere ob dieses oder diese an der Decke, der Brüstung und/oder dem Boden angeordnet sind. Hierbei ist es möglich, dass das oder die Klimageräte eine Quelllüftung und/oder eine Mischquelllüftung realisieren.Furthermore, the fan speed of the air conditioner or the air conditioning units preferably also according to the ventilation method, which can / can be operated in source ventilation or mixed-source ventilation. Furthermore, there is a dependency on the placement of the air conditioner or devices, in particular whether this or these are arranged on the ceiling, the balustrade and / or the floor. In this case, it is possible for the air conditioning unit (s) to realize a source ventilation and / or mixed source ventilation.
Möglich ist auch eine Stoßlüftung, bei der die Außenluftöffnung, insbesondere das Fenster oder dergleichen periodisch geöffnet wird. Auch ein Wechselbetrieb - Fenster auf, Klimaanlage aus oder Fenster zu, Klimaanlage ein - ist denkbar.Also possible is a breather in which the outside air opening, in particular the window or the like is opened periodically. Also a change of operation - window on, air conditioning off or window closed, air conditioning on - is conceivable.
