An air mixing chamber (1.1) with air outlets (1.11, 1.12, 1.13, 1.14) is arranged behind the heat exchanger (2). A bypass channel (1.2, 1.3) is arranged between the right, respectively left outer wall (1.4, 1.5) of the preferably rectangular heat exchanger (2) on the one hand and the respective outer side wall of the main air channel (1) on the other hand, to allow the inflowing cold air stream to enter directly the air mixing chamber (1.1), bypassing the heat exchanger (2). At least one air mixing valve (5, 6, 7, 8) that regulates the passage of the cold air stream through the respective bypass channel (1.2, 1.3) may be adjusted in intermediate positions between an opening position for the heat exchanger (2) in which the bypass channel (1.2, 1.3) is closed and a heat exchanger closing position in which the bypass channel is open.

Description

Nach dem Mischluftprinzip arbeitendes Heiz- bzw. KlimagerätHeating or air conditioning unit working according to the mixed air principle
Die Erfindung bezieht sich auf ein nach dem Mischluf prinzip arbeitendes Heiz- bzw. Klimagerät gemäß .Anspruch 1.The invention relates to a heating or air-conditioning device according to the principle of mixed air. Claim 1.
Durch die US-PS-4 383 642 ist ein nach dem Mischluftprinzip arbeitendes Heiz- bzw. Klimagerät bekannt, bei dem der Wär e- tauscher einseitig in einer Vertiefung des Hauptluftkanals schräg zum einströmenden Luftström angeordnet und eingangs- seitig durch eine gehäusefeste, in den Hauptluftström ragende Begrenzungswand und im Kaltluftbetrieb durch eine an¬ schließende Schwenkklappe verschließbar ist, die für einen Mischluft- bzw. Warmluftbetrieb aus der vorgenannten Schlie߬ stellung wegschwenkbar ist und dabei den Zutritt des einströ¬ menden Luftstroms zu dem Wärmetauscher freigibt bzw. den di¬ rekten Zutritt des einströmenden Kaltluftstroms über einen einseitigen Bypass an der Oberseite des Wärmetauschers zu einem anschließenden Mischraum mehr oder weniger absperrt.US Pat. No. 4,383,642 discloses a heating or air-conditioning device that works according to the mixed air principle, in which the heat exchanger is arranged on one side at an angle in a depression in the main air duct at an angle to the inflowing air flow and on the input side through a housing-fixed in the Main air flow projecting boundary wall and can be closed in cold air operation by a subsequent swivel flap, which can be swung away from the aforementioned closed position for mixed air or warm air operation and thereby enables the inflow of air to enter the heat exchanger or the direct one Access to the incoming cold air flow is more or less blocked via a one-sided bypass on the top of the heat exchanger to a subsequent mixing room.
Gemäß Aufgabe vorliegender Erfindung kann bei vereinfachter Bauart und geringeren Strömungsverlusten eine wirksamere Mischluftsteuerung durch ein gemäß aAnspruch 1 aufgebautes Heiz- bzw. Klimagerät erreicht werden; vorteilhafte Ausge¬ staltungen der Erfindung sind jeweils Gegenstand der Unter¬ ansprüche.According to the object of the present invention, with a simplified design and lower flow losses, more effective mixed air control can be achieved by means of a heating or air conditioning device constructed in accordance with claim 1; advantageous embodiments of the invention are the subject matter of the subclaims.
Durch die mittige Anordnung des Wärmetauschers in dem Haupt- luftkanal und quer zu dem einströmenden Luftstrom ist bei direkter umlenkungsfreier Luftströmung die gesamte Vorder¬ seite des Wärmetauschers direkt beschickbar und bei gleich¬ zeitiger einfacher Mischluftsteuerung durch die Mischluft¬ klappen beiderseits des Wärmetauschers eine Luftförderung zu der Mischluftkammer und deren Luftauslässen, insbesondere im Sinne einer Aufteilung der ausgangsseitigen Luftströme in einen linken und einen rechten Fahrzeugteil, bei gegenüber bekannten Lösungen wesentlich reduziertem Anlagenwiderstand erreicht, wobei im reinen Kühlluftbetrieb die Mischluftklap¬ pen in ihrer einen Schließstellung gleichzeitig eine volle Abdeckung zumindest der gesamten Vorderseite des Wärmetau¬ schers ermöglichen. In vorteilhafter Weise können dabei die zur Mischluftregulierung und zum Verschluß der Eintrittseite des Wärmetauschers benutzten Mischluftklappen als luftfüh¬ rende Luftflügel im Sinne der vorgenannten verlustfreien Luftlenkung vom Hauptluftkanal zu den Luftauslässen am Aus¬ gang des Luftmischraums mitausgebildet sein.Due to the central arrangement of the heat exchanger in the main air duct and transversely to the inflowing air flow, the entire front side of the heat exchanger can be fed directly in the case of direct deflection-free air flow and, with simultaneous simple mixed air control by the mixed air flaps, air can be conveyed to both sides of the heat exchanger Mixed air chamber and its air outlets, in particular in the sense of dividing the air flows on the outlet side into a left and a right part of the vehicle, achieved in system resistance which is substantially reduced compared to known solutions, with the mixed air flaps in their one closed position simultaneously permitting full coverage of at least the entire front of the heat exchanger in its one closed position. In an advantageous manner, the mixed air flaps used for mixed air regulation and for closing the inlet side of the heat exchanger can also be designed as air-guiding air wings in the sense of the aforementioned loss-free air guidance from the main air duct to the air outlets at the outlet of the air mixing space.
Dadurch daß nach einer Ausgestaltung der Erfindung je Bypass¬ kanal sowohl eine eingangsseitige erste Mischluftklappe als auch eine ausgangsseitige zweite Mischluftklappe vorgesehen sind, kann neben einer besseren gezielten Luftleitung insbe¬ sondere auf einfache Weise nicht nur die Eintrittsseite son¬ dern auch die Austrittseite des Wärmetauschers voll ver¬ schlossen und damit auf einfache Weise bei reinem Kühlluftbe- trieb eine unerwünschte Aufheizung der in den Mischraum ein¬ strömenden Kühlluft durch unerwünschten Wärmekontakt mit der Ausgangsseite des Wärmetauschers verhindert werden.Due to the fact that, according to one embodiment of the invention, both an inlet-side first mixed air flap and an outlet-side second mixed air flap are provided for each bypass channel, not only the inlet side but also the outlet side of the heat exchanger can be full in addition to a better targeted air line closed and thus in a simple manner with pure cooling air operation, undesired heating of the cooling air flowing into the mixing space can be prevented by undesired thermal contact with the outlet side of the heat exchanger.
Zur Erzielung einer möglichst kompakten Bauform ist nach einer Ausgestaltung der Erfindung vorgesehen, die Mischluft¬ klappen nicht als Schwenkklappen sondern zumindest teilweise als Mischluftschieber auszubilden, die zweckmäßigerweise in der Ebene der Eintrittsseite bzw. der Austrittsseite des Wärmetauschers zwischen ihren Öffnungs- bzw. Verschlußstel- lungen auf engstem Raum verstellbar sind.To achieve the most compact possible design, according to one embodiment of the invention, the mixed air flaps are not designed as swivel flaps but at least partially as mixed air slides, which are expediently located in the plane of the inlet or outlet side of the heat exchanger between their open or closed positions are adjustable in a confined space.

FIG 1 zeigt die totale Seitenansicht eines nach dem Misch¬ luftprinzip arbeitenden Klimagerätes mit einem Hautpluftkanal 1, in den ein durch einen Ventilator 3 angesaugter Luftstrom eintritt und durch einen Verdampfer 4 und einen Wärmetauscher 2 bzw. über seitlich des Wärmetauschers 2 vorgesehene Bypässe 1.2 bzw.1.3 zu einer Luft-Mischkammer 1.1 und zu austritts- seitigen Luftauslässen 1.11 bzw.1.12 bzw.1.13 bzw.1.14 für "Defrost" bzw. "Mittelebene" bzw. "Fußraum" bzw. "Fondraum" gefördert wird. Der Wärmetauscher 2 ist mittig im wesent- liehen quer und direkt zum einströmenden Kaltluftstrom derart angeordnet, daß er bei vorzugsweise rechteckförmiger Ausfüh¬ rungsform mit seiner unteren Seitenwandung bzw. seiner oberen Seitenwandung dicht an die korrespondierende untere Außen- Seitenwandung 1.6 bzw. obere Außen-Seitenwandung 1.7 des Hauptluftkanals 1 anschließt und mit seiner rechten Seiten¬ wandung 2.1 bzw. seiner linken Seitenwandung 2.2 derart zur jeweils benachbarten Außen-Seitenwandung 1.4 bzw.1.5 des Hauptluftkanals 1 beabstandet ist, daß jeweils ein seitlicher Bypasskanal 1.2 bzw.1.3 für einen direkten Zugang des ein- strömseitigen Kaltluftstroms an dem Wärmetauscher 2 vorbei in die hinter dem Wärmetauscher 2 vorgesehene Luftmischkammer 1.1 möglich ist.1 shows the total side view of an air conditioner working according to the mixed air principle with a main air duct 1, into which an air flow drawn in by a fan 3 enters and through an evaporator 4 and a heat exchanger 2 or bypasses 1.2 or provided on the side of the heat exchanger 2 or 1.3 to an air mixing chamber 1.1 and to outlet-side air outlets 1.11 or 1.12 or 1.13 or 1.14 for "defrost" or "middle level" or "footwell" or "rear room". The heat exchanger 2 is arranged in the middle, essentially transversely and directly to the incoming cold air flow, in such a way that, with a preferably rectangular embodiment, its lower side wall or its upper side wall is close to the corresponding lower outer side wall 1.6 or upper outer side wall 1.7 connects the main air duct 1 and is spaced with its right side wall 2.1 or its left side wall 2.2 from the adjacent outer side wall 1.4 or 1.5 of the main air duct 1 in such a way that a lateral bypass duct 1.2 or 1.3 for direct access to the upstream cold air flow past the heat exchanger 2 in the air mixing chamber 1.1 provided behind the heat exchanger 2 is possible.
FIG 2 bis 4 zeigen in Detailausschnitten aus FIG 1 jeweils gemäß Schnittverlauf II-II in FIG 1 drei verschiedene erfin¬ dungsgemäße Ausführungsformen von Mischluf einstellungen mit¬ tels erster vorderseitiger Mischluftklappen 5;7 und gegebe¬ nenfalls zweiter rückseitiger Mischluftklappen 6;8.2 to 4 show in detail from FIG. 1, each in accordance with the section line II-II in FIG. 1, three different embodiments of mixed air settings according to the invention by means of first mixed air flaps 5; 7 on the front and optionally second mixed air flaps 6; 8 on the rear.
Gemäß FIG 2 ist jeweils eine erste Mischluftklappe 5 bzw.7 am Eingang des Bypasskanals 1.2 bzw.1.3 sowie jeweils eine zwei¬ te Mischluftklappe 6 bzw.7 am Ausgang des Bypasskanals 1.2 bzw.1.3 vorgesehen. Gemäß FIG 2 sind die Mischluftklappen um Schwenkpunkte zwischen ihren Öffnungs- bzw. Verschlußstel- lungen verschwenkbar angeordnet, wobei die Schwenkpunkte im wesentlichen in der Ebene der Eintrittsseite bzw. der Aus¬ trittsseite des Wärmetauschers 2 angeordnet sind. Die Misch- luftklappen 5;6 sind jeweils mit ausgezogener Kontur in ihrer einen Verschlußstellung dargestellt, in der der rechte By- passkanal für einen direkten Durchtritt der einströmseitigen Kaltluft in die Luftmischkammer 1.1 gesperrt ist und somit der gesamte, vom Ventilator 3 geförderte Luftström durch den Wärmetauscher 2 hindurchtritt. Die Mischluftklappen 7;8 für den linken Bypasskanal 1.3 und damit auch für die linke Fahr- zeugraumhälfte bei entpsrechender getrennter Einstellung sind mit ausgezogener Kontur in einer Zwischenstellung eingezeich¬ net. In strichlierter Kontur sind der Schwenkbereich der Mischluftklappen 5;6 bzw.7,-8 bis zu ihrer jeweils anderen Verschlußstellung der Eintritts- bzw. Austrittsseite des Wärmetauschers 2 einerseits bei gleichzeitiger Öf nungsstel¬ lung der Bypasskanäle 1.2 bzw.1.3 andererseits eingezeichnet; zwischen den beiden jeweiligen Endstellungen sind beliebige Zwischenstellungen ansteuerbar. Nach einer Ausgestaltung der Erfindung sind jeweils die ersten und die zweiten, jedem By- passkanal zugeordneten Mischluf klappen gemeinsam verstell¬ bar. Es dürfte ersichtlich sein, daß durch das Verschwenken der Mischluftklappen 5;6 b∑w.7,-8 auf einfache Weise ein Mischen von Kaltluft und Warmluft bzw. ein reiner Kaltluftbetrieb ohne unerwünschte Aufwärmung durch den Wärmetauscher 2 auf- grund des vollständigen Verschlusses seiner Eintritts- und Austrittsseite im Kaltluftbetrieb sowie eine weitgehende Strömungswiderstandlose Verteilung der Luft zu den Luftaus¬ lässen der Ausgangsseite der Luftmischkammer 1.1, insbeson¬ dere zur Verteilung in einen linken und rechten Fahrzeugteil, bei gleichzeitig leichter gegebenenfalls gewünschter ge¬ trennter Regelung für eine linke bzw. rechte Fahrzeugraum- hälfte möglich ist.According to FIG. 2, a first mixed air flap 5 or 7 is provided at the input of the bypass channel 1.2 or 1.3 and a second mixed air flap 6 or 7 is provided at the output of the bypass channel 1.2 or 1.3. According to FIG. 2, the mixed air flaps are arranged to be pivotable about pivot points between their open or closed positions, the pivot points being arranged essentially in the plane of the inlet side or the outlet side of the heat exchanger 2. The mixed air flaps 5, 6 are each shown with an extended contour in their one closed position, in which the right bypass duct is blocked for a direct passage of the cold air on the inflow side into the air mixing chamber 1.1 and thus the entire air flow conveyed by the fan 3 through the Heat exchanger 2 passes through. The mixed air flaps 7, 8 for the left bypass duct 1.3 and thus also for the left half of the vehicle compartment, with the appropriate separate setting, are drawn with an extended contour in an intermediate position. The swivel range of the mixed air flaps 5, 6 and 7, -8 up to their respective other closed positions on the inlet and outlet sides of the heat exchanger 2, on the one hand, with the simultaneous opening position of the bypass ducts 1.2 and 1.3, on the other hand, are drawn in a dashed outline; Any intermediate positions can be controlled between the two respective end positions. According to one embodiment of the invention, the first and the second mixed air, which are assigned to each bypass channel, can be adjusted jointly. It should be apparent that by pivoting the mixed air flaps 5; 6 or 7, -8, mixing cold air and warm air or a pure cold air operation without undesired warming up by the heat exchanger 2 due to the complete closure of it is possible Inlet and outlet side in cold air operation as well as a largely flow-free distribution of the air to the air outlets on the outlet side of the air mixing chamber 1.1, in particular for distribution into a left and right vehicle part, while at the same time easier, if desired, desired regulation for a left or left right half of the vehicle compartment is possible.
FIG 3 zeigt in Abänderung zu FIG 2 eine Anordnung der ersten bzw. zweiten Mischluftklappen 5;7 bzw.6;8, bei der die3 shows an arrangement of the first and second mixed air flaps 5; 7 and 6; 8, in which the
Schwenkpunkte zumindest der eintrittsseitigen ersten Misch- luftklappen 5 bzw.7 um Schwenkpunkte verschwenkbar sind, die im Abstand zu der Eintrittsseite des Wärmetauschers 2 liegen.Pivot points of at least the inlet-side first mixed air flaps 5 and 7 are pivotable about pivot points which are at a distance from the inlet side of the heat exchanger 2.
Die Mischluftklappen 7;8 des linken Bypasskanals 1.3 sind dabei in Verschlußstellung für diesen Bypasskanal und die Mischluftklappen 5;6 für den rechten Bypasskanal 1.2 in einer Zwischenstellung gezeichnet; wiederum können in der einen Verschlußstellung beider Mischluftklappen die gesamte Vorder- seite bzw. Rückseite des Wärmetauschers bei reinem Frisch- luftbetrieb voll abgedeckt werden.The mixed air flaps 7; 8 of the left bypass channel 1.3 are drawn in the closed position for this bypass channel and the mixed air flaps 5; 6 for the right bypass channel 1.2 in an intermediate position; in turn, in one closed position of both mixed air flaps, the entire front or back of the heat exchanger can be fully covered in pure fresh air mode.
FIG 4 zeigt eine hinsichtlich des notwendigen Einbauraums be¬ sonders kompakte erfindungsgemäße Ausführung eines Klimage- rätes, bei der die Mischluftklappen 5;6 bzw.7;8 zwischen ihren Öffnungs- bzw. Verschlußstellungen verschiebbar, insbe¬ sondere in der Ebene der Eintrittsseite bzw. der Austritts- seite des Wärmetauschers 2, angeordnet sind. D4 shows a particularly compact embodiment of an air conditioning unit according to the invention with regard to the necessary installation space, in which the mixed air flaps 5; 6 or 7; 8 can be displaced between their open or closed positions, in particular in the plane of the inlet side or the outlet side of the heat exchanger 2 are arranged. D
In vorteilhaf er Weise sind nach einer weiteren Ausgestaltung der Erfindung im Sinne einer möglichst strömungswiderstands- losen direkten Zuführung ohne Luftumlenkung an der oberen Seite der Mischkammer 1.1 die Luftauslässe für "Defrost" und "Mittelebene" und an der unteren Seite der Luftmischkammer 1.1 die Luftauslässe für den "Fußraum" und gegebenenfalls den "Fondraum" vorgesehen, wobei zweckmäßigerweise dem rechten Bypasskanal ein Luftauslaß "Fußraum" für den rechten Fahr¬ zeugraum und dem linken Bypasskanal 1.3 ein Luftauslaß "Fuß- räum" für den linken Fahrzeugraum zugeordnet ist. According to a further embodiment of the invention, in the sense of a flow-free direct supply without air deflection on the upper side of the mixing chamber 1.1, the air outlets for “defrost” and “middle plane” and on the lower side of the air mixing chamber 1.1 are the air outlets for the "footwell" and possibly the "rear room" are provided, with an air outlet "footwell" for the right vehicle compartment and the left bypass duct 1.3 expediently being assigned an air outlet "footwell" for the left vehicle compartment to the right bypass duct.
