Description

Die Erfindung betrifft eine Vorrichtung zum Heizen und/oder Kühlen von Luft mit einem luftdurchströmten Wärmetauscher, der in einem Gehäuse angeordnet ist, das einen Kanal für den Luftstrom bildet, wobei das Gehäuse an seinem Ende einen Luftauslaß bildet, in dem und/oder vor dem Lamellen zum Leiten des austretenden Luftstroms befestigt sind.The invention relates to a device for heating and / or cooling air with an air-flow heat exchanger, which is arranged in a housing which forms a channel for the air flow, the housing at its end forming an air outlet in and / or in front of the Slats for guiding the emerging air flow are attached.

Es sind Luftheizgeräte bekannt, die im Luftauslaß Lamellen besitzen, um den, in den Raum austretenden Luftstrahl je nach Bedarf in verschiedene Richtungen lenken zu können. Hierzu ist es darüberhinaus aus der deutschen Offenlegungsschrift 3638616 bekannt, vor dem Luftauslaß Lamellenpaare V-förmig zu befestigen, wobei die seitlichen Stirnseiten jedes Lamellenpaares offen sind, um Sekundärluft eintreten zu lassen. Hierdurch wird eine frühe Durchmischung und eine tiefere Raumdurchspülung erreicht.Air heaters are known which have fins in the air outlet in order to be able to direct the air jet emerging into the room in different directions as required. For this purpose, it is also known from German Offenlegungsschrift 3638616 to attach pairs of fins in front of the air outlet in a V-shape, the side faces of each pair of fins being open to allow secondary air to enter. As a result, an early mixing and a deeper flushing of the room is achieved.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Heizen und/oder Kühlen von Luft in der Weise zu verbessern, daß bei einfacher Konstruktion und variabler Raumdurchspülung ein sehr frühes Einmischen von Raumluft in den Luftstrom erfolgt.The object of the invention is to improve a device for heating and / or cooling air in such a way that with simple construction and variable room flushing, room air is mixed very early into the air flow.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Bereich zwischen dem Luftauslaß und dem Wärmetauscher in der Gehäuseseitenwand mindestens eine Lufteinlaßöffnung angeordnet ist, und daß unmittelbar vor der Lufteinlaßöffnung der Kanal eine Querschnittsverengung besitzt.This object is achieved in that at least one air inlet opening is arranged in the area between the air outlet and the heat exchanger in the housing side wall, and in that the duct has a cross-sectional constriction directly in front of the air inlet opening.

Durch die erhöhte Luftgeschwindigkeit im Bereich der Querschnittsverengung wird hinter der Querschnittsverengung ein Unterdruck erzeugt, durch den Raumluft durch die Lufteinlaßöffnung (EN) in die Vorrichtung eingesaugt wird, so daß der erwärmte oder gekühlte Luftstrom hinter dem Wärmetauscher sehr früh mit Raumluft vermischt wird. Dies führt zu einer Veränderung der Luftstrahltemperatur und zu einer Erhöhung der Luftaustrittsgeschwindigkeit und damit zu einer erhöhten Raumdurchspülung und einer Reduzierung der Thermik. Die Vorrichtung ist hierbei von einfachstem konstruktiven Aufbau und es ist nicht erforderlich, die den Luftstrom leitenden Lamellen anders als üblich auszuführen.Due to the increased air speed in the area of the cross-sectional constriction, a negative pressure is generated behind the cross-sectional constriction, through which room air is sucked into the device through the air inlet opening (EN), so that the heated or cooled air flow behind the heat exchanger is mixed with room air very early. This leads to a change in the air jet temperature and to an increase in the air outlet speed and thus to an increased flushing of the room and a reduction in the thermals. The device is of the simplest structural design and it is not necessary to design the lamellae guiding the air flow differently than usual.

Die Vorrichtung zum Heizen und/oder Kühlen von Luft weist ein Gehäuse 1 auf, das einen Lufkanal 2 bildet, dessen Querschnitt über die gesamte Länge L des Gehäuses bis auf eine Querschnittsverengung Q gleich bleibt. Die Luft strömt über einen Einlaß 3 in das Gehäuse ein und wird durch einen Ventilator 4 in Richtung des Pfeiles 5 bewegt. Statt des Ventilators 4 kann die Vorrichtung, bzw. das Gehäuse 1 auch an dem Auslaß eines nicht dargestellten Luftkanals angeschlossen sein, der die Vorrichtung mit Luft versorgt.The device for heating and / or cooling air has a housing 1 which forms an air duct 2, the cross section of which remains the same over the entire length L of the housing except for a cross-sectional constriction Q. The air flows into the housing via an inlet 3 and is moved in the direction of arrow 5 by a fan 4. Instead of the fan 4, the device or the housing 1 can also be connected to the outlet of an air channel, not shown, which supplies the device with air.

Hinter dem Einlaß 3, bzw. dem Ventilator 4 befindet sich in Strömungsrichtung 5 ein Wärmetauscher 6, der etwa über die gesamte Breite des Kanals 2 angeordnet ist und von der Luft durchströmt wird. Der Wärmetauscher 6 heizt oder kühlt die Luft, um damit die Luft eines Raumes zu Heizen oder zu Kühlen.Behind the inlet 3 or the fan 4 there is a heat exchanger 6 in the direction of flow 5, which is arranged approximately over the entire width of the channel 2 and through which the air flows. The heat exchanger 6 heats or cools the air, thereby heating or cooling the air of a room.

Die erwärmte oder gekühlte Luft tritt aus einem Luftauslaß aus der Vorrichtung aus, wobei im und/oder vor dem Luftauslaß 7 Lamellen 8 parallel zueinander angeordnet sind, die den austretenden Luftstrom leiten und verstellbar sein können. Der Luftauslaß 7 ist entweder vom Ende des Gehäuses 1 oder einem Rahmen 8 umgeben, der Teil des Gehäuses 1 sein kann. Alternativ kann der Rahmen 8 aber auch ein Teil sein, das vor dem Gehäuseteil befestigt ist, das den Wärmetauscher 6 und insbesondere den Ventilator 4 enthält.The heated or cooled air exits the device from an air outlet, 7 and 8 lamellae 8 being arranged parallel to one another in and / or in front of the air outlet, which guide the escaping air flow and can be adjustable. The air outlet 7 is either surrounded by the end of the housing 1 or a frame 8, which can be part of the housing 1. Alternatively, the frame 8 can also be a part which is fastened in front of the housing part and which contains the heat exchanger 6 and in particular the fan 4.

Zwischen dem Luftauslaß 7 und insbesondere den Lamellen 8 und dem Wärmetauscher 6 sind im Gehäuse 1, bzw. hinter dem Gehäusebereich, der den Wärmetauscher enthält Lufteinlaßöffnungen vorgesehen, durch die Raumluft in das Innere der Vorrichtung und damit in den Luftstrom gelangt, der aus dem Wärmetauscher austritt. In Strömungsrichtung vor den Lufteinlaßöffnungen besteht eine Querschnittsverengung Q, die den vom Wärmetauscher 6 kommenden Luftstrom einengt und damit die Strömungsgeschwindigkeit erhöht. Da direkt hinter dieser Querschnittsverengung Q die Lufteinlaßöffnungen sich befinden, führt der durch die Querschnittsverengung erzeugte Unterdruck zu einem Ansaugen von Raumluft durch die Lufteinlaßöffnungen 9, so daß durch die Öffnungen 9 Raumluft in den Hauptluftstrom der Vorrichtung eingemischt wird und im vermischten Zustand aus dem Luftauslaß 7 austritt. Die Querschnittsverengung Q wird im Ausführungsbeispiel durch jeweils ein festes Leitblech 10 gebildet, das seitlich an der Gehäusewand 1 nahe der Öffnung 9 befestigt ist und mit einer Neigung von 30 bis 60 Grad, insbesondere von 45 Grad in das Innere des Gehäuses und damit in den Hauptluftstrom hineinragt. Statt eines starren oder beweglichen Leitblechs 10 als Flächenteil kann aber auch ein Hohl- körper oder Profil die Querschnittsverengung an dieser Stelle bilden. Ferner reicht es auch aus, daß die Gehäusewand nach innen eingebogen ist.Between the air outlet 7 and in particular the fins 8 and the heat exchanger 6 are provided in the housing 1, or behind the housing area, which contains the heat exchanger, air inlet openings through the room air into the interior of the device and thus into the air flow that comes out of the heat exchanger exit. In the flow direction in front of the air inlet openings, there is a cross-sectional constriction Q, which constricts the air flow coming from the heat exchanger 6 and thus increases the flow speed. Since the air inlet openings are located directly behind this cross-sectional constriction Q, the negative pressure generated by the cross-sectional constriction leads to a suction of room air through the air inlet openings 9, so that room air is mixed into the main air flow of the device through the openings 9 and from the air outlet 7 in the mixed state exit. The cross-sectional constriction Q is formed in the exemplary embodiment by a fixed baffle 10, which is fastened to the side of the housing wall 1 near the opening 9 and with an inclination of 30 to 60 degrees, in particular 45 degrees, into the interior of the housing and thus into the main air flow protrudes. Instead of a rigid or movable guide plate 10 as a flat part, a hollow body or profile can also form the cross-sectional constriction at this point. It is also sufficient that the housing wall is bent inwards.

In Höhe jeder Lufteinlaßöffnung 9 ist im Gehäuse im Bereich der Querschnittsverengung Q nahe der Öffnung 9 ein bewegliches Luftleitteil 11 verdrehbar (alternativ und/oder verschiebbar) gelagert, das die in Figuren 3-5 gezeigten Stellungen einnehmen kann. In der Stellung nach Figur 3 steht das Luftleitteil 11 parallel zum Leitblech 10 in einem Abstand zum Leitblech, so daß zwischen Luftleitteil 11 und Leitblech 10 ein Kanal 12 gebildet wird, der einen Stützstrom erzeugt der das Einsaugen von Raumluft, insbesondere zu Beginn der Arbeit des Gerätes unterstützt. Je nach Stellung des Leitblechs wird die Luftaustrittsgeschwindigkeit verändert.At the level of each air inlet opening 9, a movable air guide part 11 is rotatably (alternatively and / or displaceably) mounted in the housing in the area of the cross-sectional constriction Q near the opening 9 and can take the positions shown in FIGS. 3-5. In the position shown in Figure 3, the air guide 11 is parallel to the baffle 10 at a distance from the baffle, so that between the air baffle 11 and baffle 10, a channel 12 is formed, the one Support current generates the intake of room air, especially at the beginning of the work of the device. The air outlet speed changes depending on the position of the baffle.

In der Stellung nach Figur 4 verlängert das Luftleitteil 11 das Leitblech 10, so daß die Querschnittsverengung Q erheblich vergrößert und damit der Unterdruck, die Einsaugleistung und die Luftgeschwindigkeit erhöht werden. In der Stellung nach Figur 5 steht das Luftleitteil 11 parallel zum Hauptluftstrom, so daß seine Wirkung in etwa aufgehoben ist. Zwischen den Stellungen nach Figur 3-5 kann das Luftleitteil 11 in verschiedene Zwischenstellungen je nach Bedarf gedreht oder in einem nicht dargestellten Ausführungsbeispiel verschoben werden, um die Luftgeschwindigkeit zu verändern.In the position according to FIG. 4, the air guide part 11 extends the guide plate 10, so that the cross-sectional constriction Q is considerably enlarged and the vacuum, the suction power and the air speed are increased. In the position shown in Figure 5, the air guide 11 is parallel to the main air flow, so that its effect is approximately canceled. Between the positions according to FIGS. 3-5, the air guide part 11 can be rotated into various intermediate positions as required or, in an exemplary embodiment not shown, can be shifted in order to change the air speed.

Im Ausführungsbeispiel weist das Gehäuse einen rechteckförmigen Querschnitt auf. Alternativ sind aber auch andere Querschnittsformen, insbesondere eine kreisförmige Querschnittsform möglich. Die Anzahl der Lufteinlaßöffnungen 9 kann je nach Art und Größe der Öffnungen als auch nach dem Verwendungszweck der Vorrichtung unterschiedlich sein. Vorzugsweise sind zwei, einander gegenüberliegende Lufteinlaßöffnungen in zwei einander gegenüberliegenden Wänden des Gehäuses vorgesehen.In the exemplary embodiment, the housing has a rectangular cross section. Alternatively, however, other cross-sectional shapes, in particular a circular cross-sectional shape, are also possible. The number of air inlet openings 9 can vary depending on the type and size of the openings and also on the intended use of the device. Preferably, two opposing air inlet openings are provided in two opposing walls of the housing.

Um die Lufteinlaßöffnungen 9 zu bilden, kann ein Zwischenteil zwischen dem Luftauslaß, bzw. dem Rahmen 8 und dem Hauptgehäuse Teil 1 befestigt werden. Alternativ kann aber auch das Gehäuse eine Verlängerung zur Bildung der Lufteinlaßöffnungen besitzen.In order to form the air inlet openings 9, an intermediate part between the air outlet or the frame 8 and the main housing part 1 can be attached. Alternatively, the housing can also have an extension to form the air inlet openings.
