Description

Die Erfindung betrifft einen Sockelquellauslaß aus einem Gehäuse mit einem Zuluftanschluß und einem Quelluftaustritt zur Einbringung von Zuluft in einen zu konditionierenden Raum.The invention relates to a base source outlet from a housing with a Supply air connection and a source air outlet for introducing supply air into a conditioning space.

Ein derartiger Sockelquellauslaß ist durch eine "Technische Information, Luftführungssysteme, Quellauslaß für Sockelanbau" der Firma H. Krantz-TKT GmbH bekannt geworden. Die Zuluft tritt bei solchen Quellauslässen für den Sockelanbau von unten aus einem Hohlraumboden oder speziellen Zuluftschächten in einen unten am Gehäuse angebrachten Zuluftanschluß ein. Ein solcher Sockelquellauslaß besteht im wesentlichen aus einem Lochblechgehäuse, einem Luftverteilkasten mit einem Zuluftanschluß, einem im Inneren angeordneten Lochblech sowie einer Drosselklappe. Ferner ist ein Sockelquellauslaß auch aus der EP-A-0615 103 bekannt.Such a base source outlet is characterized by a "technical information, air duct systems, Source outlet for base mounting "from H. Krantz-TKT GmbH known. The supply air comes in such source outlets for the base mounting from below from a cavity floor or special supply air ducts in a supply air connection at the bottom of the housing. Such a base source outlet consists essentially of a perforated sheet metal housing, an air distribution box with a supply air connection, a perforated plate arranged inside and a throttle valve. There is also a base source outlet also known from EP-A-0615 103.

Der Auslaß wird im Sockelbereich einer Wand so angeordnet, daß der Luftverteilkasten durch den Fußboden in den darunter liegenden Hohlraumboden hinein ragt. Die Zuluft strömt aus einem Hohlraum im Boden über den Zuluftanschluß in den Luftverteilkasten ein und wird durch das innenliegende Lochblech gleichmäßig über die Auslaßlänge verteilt. Das Lochblechgehäuse erzeugt dabei eine turbulenzarme Verdrängungsströmung mit niedrigem Impuls und großer Eindringtiefe. Durch die mehrfach abgewinkelte Form des Lochblechgehäuses wird die Zuluft jeweils in Teilmengen sowohl waagerecht als auch schräg nach oben sowie auch senkrecht nach oben ausgeblasen. Gleich nach dem Austritt aus dem Auslaß legt sich die Zuluft an den Boden an und strömt tief in den Raum ein. Aufgrund vorhandener thermischer Kräfte im Raum (Personen, elektrische Geräte) bilden sich absolut zugfreie Quellströmungen mit sehr kleinen Geschwindigkeiten vom Boden bis zur Decke. Die erwärmte und verbrauchte Raumluft wird an der Decke abgesaugt. Die Zuluft wird in der Regel mit 1 bis 3 K unter Raumtemperatur ausgeblasen und erwärmt sich auf ihrem Weg vom Boden bis zur Decke auf ca. 2 bis 4 K über der Raumtemperatur.The outlet is arranged in the base area of a wall so that the air distribution box through the floor into the cavity floor below protrudes. The supply air flows from a cavity in the floor through the supply air connection into the air distribution box and becomes even through the perforated plate on the inside distributed over the outlet length. The perforated plate housing creates one Low-turbulence displacement flow with a low pulse and a large depth of penetration. Due to the multiple angled shape of the perforated plate housing the supply air in partial quantities both horizontally and diagonally upwards and also blown out vertically upwards. Immediately after leaving At the outlet, the supply air settles on the floor and flows deep into the room on. Due to existing thermal forces in the room (people, electrical Devices), absolutely draft-free source flows are formed at very low speeds from floor to ceiling. The warmed and used room air is suctioned off the ceiling. The supply air is usually 1 to 3 K below Blown out at room temperature and warms up on its way from the floor to to the ceiling at about 2 to 4 K above room temperature.

Da die Temperaturdifferenz zwischen der Zuluft und der Raumtemperatur regelmäßig zu gering ist, ist zur Temperierung solchermaßen mit Zuluft versorgter Räume eine zusätzliche Heiz- bzw. Kühleinrichtung erforderlich. Diese kann zum Beispiel in Form eines separat, vorzugsweise unter einem Fenster, montierten Konvektors oder auch eines Radiators ausgebildet sein. In jedem Fall ist zum ausgleichenden Beheizen und Kühlen eine separate Einrichtung erforderlich, die zusätzliche Installationen sowie zusätzlichen Bauraum benötigt. Des weiteren tritt die Optik solcher zusätzlicher Einrichtungen in der Regel als negativ in Erscheinung. Because the temperature difference between the supply air and the room temperature is regular is too low, is thus supplied with supply air for temperature control Rooms an additional heating or cooling device is required. This can be used Example in the form of a separately, preferably mounted under a window Convector or a radiator can be formed. In any case balancing heating and cooling requires a separate facility that additional installations and additional installation space are required. Furthermore the appearance of such additional devices usually appears as negative.

Der Erfindung liegt die Aufgabe zugrunde, einen Sockelquellauslaß so weiterzuentwickeln, daß unabhängig von der Temperatur der dem Auslaß zugeführten Zuluft und unter Beibehaltung der kleinen Außenabmessungen bekannter Sockelquellauslässe damit wahlweise große Heiz- und Kühlleistungen ermöglicht werden.The invention has for its object to develop a base source outlet so that regardless of the temperature of the supplied to the outlet Supply air and while maintaining the small external dimensions of known base source outlets thus optionally enables large heating and cooling capacities become.

Ausgehend von dem eingangs beschriebenen Sockelquellauslaß, ist die Aufgabe dadurch gelöst, daß innerhalb des Gehäuses in dessen Längsrichtung eine Trennwand verläuft, die den durch den Zuluftanschluß eintretenden Zuluftstrom aufteilt und sich in Strömungsrichtung mindestens bis in die Nähe einer Innenseite des Gehäuses erstreckt, sowie dadurch, daß sich zwischen der Trennwand und einer dem Inneren des Raumes abgewandten Seitenwand des Gehäuses ein Wärmetauscher angeordnet ist, der sich in Längsrichtung des Gehäuses erstreckt.Starting from the base source outlet described at the beginning, the task is solved in that within the housing in the longitudinal direction of a partition that divides the incoming air flow entering through the supply air connection and in the direction of flow at least close to an inside extends of the housing, and in that between the partition and a side wall of the housing facing away from the interior of the room Heat exchanger is arranged, which extends in the longitudinal direction of the housing.

Der erfindungsgemäße Sockelquellauslaß erfüllt bei einer sehr kompakten Bauform sowohl die Funktion eines Luftdurchlasses als auch die einer ansonsten häufig zusätzlich erforderlichen separaten Heiz- bzw. Kühleinrichtung, wodurch optisch sowie montagemäßig viele Vorteile resultieren.The base source outlet according to the invention fulfills with a very compact design both the function of an air outlet and that of an otherwise often additionally required separate heating or cooling device, whereby There are many advantages in terms of appearance and assembly.

Durch die Aufteilung des Zuluftstroms entsteht ein in bezug auf die Zulufttemperatur unveränderter Quelluftstrom, der bodennah mit einer Temperatur von 1 bis 3 K unterhalb der Raumtemperatur austritt, sowie ein den Wärmetauscher anströmender Luftstrom, dessen Temperatur mittels des Wärmetauschers beliebig beeinflußt werden kann und der den Sockelquellauslaß durch das Gehäuse nach oben verläßt. The division of the supply air flow results in a relation to the supply air temperature unchanged source air flow, close to the ground with a temperature of 1 to 3 K below the room temperature, as well as the heat exchanger incoming air flow, its temperature by means of the heat exchanger can be influenced as desired and the base source outlet through the housing leaves up.

Der erfindungsgemäße Sockelquellauslaß bietet den enormen Vorteil, daß die im Heizfall über dem Gehäuse entstehende aufwärts gerichtete Warmluftkonvektion, die dem eines normalen Heizungskonvektors entspricht, die bodennah seitlich austretende und waagerecht verlaufende Quellströmung mit einer Temperatur 1 bis 3 K unter der Raumtemperatur in keiner Weise beeinflußt. Bei dem erfindungsgemäßen Sockelquellauslaß sind folglich die Funktionen der Quelluftausbringung sowie der konvektiven Raumheizung in sehr vorteilhafter Weise miteinander vereint, ohne daß dabei ein größerer Bauraum als bei Sockelquellauslässen nach dem Stand der Technik benötigt wird.The base source outlet according to the invention has the enormous advantage that the Heating case above the housing creates upward hot air convection, which corresponds to that of a normal heating convector, close to the floor laterally emerging and horizontal source flow with a temperature 1 to 3 K below room temperature in no way affected. In which Base source outlet according to the invention are consequently the functions of the source air application and the convective space heating in a very advantageous manner united with each other, without a larger installation space than with base source outlets according to the state of the art is required.

Wird der Wärmetauscher nicht zu Heiz- oder Kühlzwecken genutzt und ist außer Betrieb, so arbeitet der erfindungsgemäße Sockelquellauslaß auf herkömmliche Weise, d. h. der Zuluftstrom tritt sowohl in waagerechter als auch senkrechter und/oder schräger Richtung ohne eine im Sockelquellauslaß erfolgte Temperaturveränderung in den Raum aus. Aufgrund der im Vergleich mit der Raumtemperatur niedrigeren Temperatur der Zuluft fällt auch der zunächst senkrecht austretende Teil der Zuluftströmung aufgrund der Schwerkraftwirkung nach einer sehr geringen Steighöhe wieder in Bodennähe ab.The heat exchanger is not used for heating or cooling purposes and is excluded Operation, the base source outlet according to the invention works on conventional Way, d. H. the supply air flow occurs both horizontally and vertically and / or oblique direction without a temperature change taking place in the base source outlet out into the room. Due to the comparison with the room temperature the lower the temperature of the supply air, the one that emerges vertically also drops Part of the supply air flow due to the force of gravity after a very low rise again near the ground.

Falls besonders große Kühlleistungen benötigt werden, bietet der erfindungsgemäße Sockelquellauslaß also zusätzlich die Möglichkeit, den Wärmetauscher im Kühlbetrieb einzusetzen, wodurch die nach oben ausströmende Zuluft aufgrund ihrer dann gegenüber der Raumluft erheblich geringeren Temperatur auf einem besonders kurzen Weg wieder in Richtung des Bodens abfällt. Die Kühlleistung läßt sich auf diese Weise selbst bei einer Zulufttemperatur, die an sich lediglich 1 bis 3 K unterhalb der Raumtemperatur liegt, ganz erheblich steigern. If particularly large cooling capacities are required, the invention offers Socket source outlet thus also the possibility of the heat exchanger use in cooling mode, which causes the supply air flowing upwards their then considerably lower temperature than the indoor air a particularly short path towards the bottom. The cooling capacity can be in this way even at a supply air temperature, which in itself 1 to 3 K below room temperature, increase considerably.

Bei dem erfindungsgemäßen Sockelquellauslaß ist noch als besonderer Vorteil hervorzuheben, daß sich die Strömungsverhältnisse im Heizfall und im Kühlfall verändern, ohne daß dazu irgendwelche mechanisch bewegten Bauteile erforderlich sind. Sowohl die Ausbildung einer insgesamt waagerechten Zuluftströmung im Kühlfall (Quelluftströmung) als auch das Entstehen einer über dem Wärmetauscher bzw. dem Sockelquellauslaß senkrecht gerichteten Warmluftströmung - zusätzlich zur weiterhin waagerecht austretenden Zuluftströmung (Teilquelluftströmung) - entsteht allein aufgrund der Schwerkraftwirkungen unterschiedlich temperierter Luftmassen.In the base source outlet according to the invention is still a particular advantage to emphasize that the flow conditions in heating and cooling change without the need for any mechanically moving components are. Both the formation of an overall horizontal supply air flow in the case of cooling (source air flow) as well as the emergence of one above the heat exchanger or the hot air flow directed vertically at the base source outlet - in addition to the horizontal supply air flow (partial source air flow) - created differently solely due to the effects of gravity tempered air masses.

Nach einer Ausgestaltung des erfindungsgemäßen Sockelquellauslasses wird vorgeschlagen, daß zwischen dem Wärmetauscher und der dem Innern des Raumes abgewandten Seitenwand des Gehäuses ein sich in dessen Längsrichtung erstreckender Sekundärluftkanal vorgesehen ist, dessen Eintrittsquerschnitt in einer Abdeckung des Gehäuses und dessen Austrittsquerschnitt seitlich versetzt unterhalb des Wärmetauschers angeordnet ist.According to an embodiment of the base source outlet according to the invention suggested that between the heat exchanger and the inside of the room side wall of the housing facing away in the longitudinal direction extending secondary air duct is provided, the inlet cross section in a cover of the housing and its outlet cross-section laterally offset is arranged below the heat exchanger.

Durch die dem Inneren des Raumes abgewandte Lage des Sekundärluftkanals, d. h. insbesondere dessen Eintrittsquerschnitts, tritt in diesen hauptsächlich Luft aus einem möglichen Kaltluftabfall an einem über dem Sockelquellauslaß angeordneten Fenster bzw. an einer kalten Außenwand ein. Diese abwärts gerichtete Strömung im Sekundärluftkanal wird dadurch verursacht, daß im Heizfall die auf den Wärmetauscher zuströmende Zuluft zu einer Induktionswirkung im Sekundärluftkanal führt und folglich Raumluft durch letzteren ansaugt. Due to the position of the secondary air duct facing away from the interior of the room, d. H. especially its inlet cross section, air mainly escapes in it from a possible drop of cold air arranged at a above the base source outlet Window or on a cold outside wall. This downward Flow in the secondary air duct is caused by the fact that the supply air flowing to the heat exchanger for an induction effect in the Secondary air duct leads and consequently draws in room air through the latter.

Auf diese Weise wird sehr wirkungsvoll einerseits ein Kaltluftabfall zum Raum hin vermieden und andererseits die Heizleistung durch die größere Temperaturdifferenz zwischen dem Wärmetauscher und der diesen anströmenden Luft erhöht.In this way, a cold air drop to the room becomes very effective avoided and on the other hand the heating power due to the larger temperature difference increased between the heat exchanger and the air flowing to it.

Gemäß einer weiteren Ausgestaltung ist vorgesehen, daß der Sekundärluftkanal mittels einer im wesentlichen parallel zur Längsachse des Gehäuses verlaufenden Trennwand von einem Wärmetauscherraum abgetrennt ist.According to a further embodiment it is provided that the secondary air duct by means of a substantially parallel to the longitudinal axis of the housing Partition is separated from a heat exchanger room.

Eine derartige Ausgestaltung des Sekundärluftkanals erfordert fertigungstechnisch nur einen geringen Aufwand und bietet eine große Gestaltungsfreiheit hinsichtlich des gewünschten Kanalverlaufs.Such a configuration of the secondary air duct requires manufacturing technology only a little effort and offers great freedom of design regarding the desired channel course.

Es ist ferner besonders vorteilhaft, für einen Zuluftübertritt von dem Zuluftanschluß in den Wärmetauscherraum eine Mehrzahl von auf den Wärmetauscher ausgerichteten Düsen vorzusehen.It is also particularly advantageous for a supply air transfer from the supply air connection in the heat exchanger space a plurality of on the heat exchanger to provide aligned nozzles.

Die Induktionswirkung wird durch die Durchströmung der Düsen erheblich verbessert, was zu einer deutlich gesteigerten Induktion von Raumluft durch den Sekundärluftkanal führt. Des weiteren wird die Heizleistung des Wärmetauschers durch die direkte Düsenanströmung gegenüber freier Konvektion um ein Vielfaches gesteigert.The induction effect is significant due to the flow through the nozzles improved, which leads to a significantly increased induction of room air by the Secondary air duct leads. Furthermore, the heat output of the heat exchanger due to the direct jet flow compared to free convection many times over increased.

Den erfindungsgemäßen Sockelquellauslaß weiter ausgestaltend, wird vorgeschlagen, daß die Düsen als Prägelochung in einem den Zuluftanschluß von dem Wärmetauscherraum abtrennenden Düsenblech ausgebildet sind. Further designing the base source outlet according to the invention, it is proposed that that the nozzles as an embossed hole in the supply air connection from the Heat exchanger space separating nozzle plate are formed.

Fertigungstechnisch stellt dies eine sehr einfach zu realisierende Möglichkeit dar, so daß die Kosten für eine derartige Konstruktion gering gehalten werden können.In terms of production technology, this is a very easy to implement option so that the cost of such a construction can be kept low.

Des weiteren ist es vorteilhaft, daß der Zuluftanschluß eintrittsseitig ein Lochblech aufweist, weil durch den damit erzeugten Druckabfall eine gleichmäßige Beaufschlagung sowohl der Düsen als auch des Eintrittsquerschnitts des Quelluftraums erzielt werden kann.Furthermore, it is advantageous that the supply air connection has a perforated plate on the inlet side has because of the pressure drop generated thereby a uniform Actuation of both the nozzles and the inlet cross section of the source air space can be achieved.

Zur Erzielung einer ansprechenden Optik des Gehäuseäußeren wird vorgeschlagen, daß dem Inneren des Raumes zugewandte Seitenwände und/oder die Abdeckung des Gehäuses als Lochbleche ausgebildet sind.To achieve an attractive appearance of the housing exterior, it is proposed that that the interior of the room facing side walls and / or the Cover of the housing are designed as perforated plates.

Des weiteren wird nach einer Ausgestaltung des erfindungsgemäßen Sockelquellauslasses vorgeschlagen, daß die Lochbleche in Längsrichtung und/oder Umfangsrichtung des Gehäuses einstückig miteinander verbunden und von dem übrigen Gehäuse abnehmbar sind. Eine solche Ausbildung erfordert fertigungstechnisch einen geringen Aufwand und erlaubt infolge der einfachen Abnehmbarkeit eine unkomplizierte Reinigung des gesamten Inneren des Sockelquellauslasses.Furthermore, according to an embodiment of the base source outlet according to the invention proposed that the perforated sheets in the longitudinal direction and / or Circumferential direction of the housing integrally connected to each other and by the remaining housing are removable. Such training requires manufacturing technology a little effort and allows due to the easy removability easy cleaning of the entire interior of the base source outlet.

Die Erfindung weiter ausgestaltend, ist vorgesehen, daß in einem vom Wärmetauscherraum abgetrennten Quelluftraum ein Lochblech im wesentlichen parallel und im Abstand zu dem Quelluftaustritt angeordnet ist. Developing the invention further, it is provided that in one of the heat exchanger space separate source air space a perforated plate essentially parallel and is arranged at a distance from the source air outlet.

Hierdurch wird eine über die gesamte Länge des Sockelquellauslasses gleichmäßige Beaufschlagung des Quelluftaustritts erreicht, wodurch eine ungleichmäßige Strömungsverteilung, die zu Zugerscheinungen führen könnte, vermieden wird.This makes a uniform over the entire length of the base source outlet Exposure to the source air outlet reached, causing an uneven Flow distribution, which could lead to drafts, is avoided.

Eine Ausbildung des Wärmetauschers als Rippenrohr oder Lamellenwärmetauscher bringt den Vorteil mit sich, daß eine Anpassung an den länglichen Bauraum besonders einfach ist.Training of the heat exchanger as a finned tube or finned heat exchanger has the advantage that an adaptation to the elongated space is particularly simple.

Nach einer weiteren Ausgestaltung des Sockelquellauslasses ist vorgesehen, daß sich sowohl der Wärmetauscher als auch der Zuluftanschluß nur über einen Teilbereich der Gesamtlänge des Gehäuses erstreckt und daß die vorgenannten Teilbereiche gleich lang und sich in vertikaler Richtung überdeckend angeordnet sind.According to a further embodiment of the base source outlet, it is provided that both the heat exchanger and the supply air connection are connected only via one Part of the total length of the housing extends and that the aforementioned Partial areas of equal length and arranged to overlap in the vertical direction are.

Hierdurch wird die Verwendung des erfindungsgemäßen Sockelquellauslasses auch bei relativ kleinen Verbindungsquerschnitten mit dem Hohlraumboden möglich.This makes the use of the base source outlet according to the invention even with relatively small connection cross sections with the cavity floor possible.

Eine Führung der Anschlußleitungen des Wärmetauschers durch Stirnseiten des Gehäuses stellt eine vorteilhafte Ausgestaltung, besonders im Hinblick auf eine lineare Anordnung einer Mehrzahl von Sockelquellauslässen, dar.A routing of the connecting lines of the heat exchanger through the end faces of the Housing represents an advantageous embodiment, especially with regard to a linear arrangement of a plurality of base source outlets.

Wird in einer Anschlußleitung zwischen dem Wärmetauscher und einer Stirnseite des Gehäuses ein Ventil vorgesehen, so ist die individuelle Beeinflussung des Medienstroms durch den Wärmetauscher möglich. Is in a connection line between the heat exchanger and an end face of the housing a valve is provided, so the individual influence of the Media flow possible through the heat exchanger.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigt:

In Fig. 1 ist dargestellt, wie ein erfindungsgemäßer Sockelquellauslaß aus einem Gehäuse 1 besteht, welches sich im wesentlichen aus einer Seitenwand 3, in die ein Quelluftauslaß 2 integriert ist, einer Abdeckung 4, einer weiteren Seitenwand 5, einem nicht näher bezeichneten Bodenblech sowie mehreren, ebenfalls nicht bezeichneten Wandteilen eines Zuluftanschlusses 6 zusammensetzt. Von der Innenseite der Seitenwand 3 verläuft eine zweifach abgewinkelte Trennwand 7 bis zu dem Bodenblech, wodurch das Innere des Gehäuses 1 in einen Quelluftraum 8 und ein verbleibendes Inneres unterteilt wird. Im Bereich der Verbindung zwischen dem Zuluftanschluß 6 und dem Quelluftraum 8 ist das Bodenblech in Form eines Lochblechs ausgebildet. Durch entsprechende Wahl der Löcherquerschnitte kann der sich bei der Durchströmung einstellende Druckverlust variiert werden. Parallel und im Abstand zu dem Quelluftaustritt 2 ist ein weiteres Lochblech 9 in dem Quelluftraum 8 angeordnet, das aufgrund des durch es verursachten Druckverlusts für eine gleichmäßige Beaufschlagung des Quelluftaustritts 2 und damit für eine gleichmäßige Zuluftausströmung sorgt. Während der Zuluftanschluß 6 eingangsseitig ebenfalls mit einem Lochblech 10 versehen ist, ist derjenige Teil des Bodenblechs, der den Zuluftanschluß 6 von einem Wärmetauscherraum 11 abtrennt, mit einer Mehrzahl von einreihig und geradlinig sich in Längsrichtung erstreckenden Prägelochungen versehen, die in Form von Düsen 12 ausgebildet sind. Die Düsen 12 sind lotrecht unter einem Wärmetauscher 13 angeordnet, der die Form eines sich in Längsrichtung des Gehäuses 1 erstreckenden Rippenrohres aufweist, und auf diesen ausgerichtet.In Fig. 1 it is shown how a socket source outlet according to the invention from a Housing 1 consists, which consists essentially of a side wall 3, in the a displacement air outlet 2 is integrated, a cover 4, a further side wall 5, an unspecified floor panel and several, also not designated wall parts of a supply air connection 6. Of the A double-angled partition 7 runs inside the side wall 3 up to the floor panel, which turns the inside of the housing 1 into a source air space 8 and a remaining interior is divided. In the area of connection between the supply air connection 6 and the displacement air space 8 is the floor panel in Form of a perforated plate. By appropriate selection of the hole cross-sections the pressure drop occurring during the flow can vary become. Another is parallel and at a distance from the source air outlet 2 Perforated plate 9 arranged in the Quellufraum 8, which due to the through it caused pressure loss for an even exposure to the source air outlet 2 and thus ensures a uniform supply air flow. While the supply air connection 6 is also provided on the inlet side with a perforated plate 10 is that part of the floor panel that connects the supply air connection 6 from one Separates heat exchanger space 11, with a plurality of single-row and straight longitudinally extending embossed holes provided in the form of Nozzles 12 are formed. The nozzles 12 are perpendicular under a heat exchanger 13 arranged which has the shape of a in the longitudinal direction of the housing 1st extending finned tube, and aligned to this.

Eine an der oberen, als Lochblech ausgeführten Abdeckung 4 befestigte zweite Trennwand 14 verläuft im wesentlichen parallel zu der Seitenwand 5. Diese Trennwand 14 teilt von dem Wärmetauscherraum 11 einen Sekundärluftkanal 15 ab, dessen Eintrittsquerschnitt in der Abdeckung 4 liegt und dessen Austrittsquerschnitt sich seitlich versetzt unterhalb des Wärmetauschers und neben den Düsen 12 befindet.A second attached to the upper cover 4 designed as a perforated plate Partition wall 14 runs essentially parallel to side wall 5 Partition 14 divides a secondary air duct 15 from the heat exchanger space 11 from whose inlet cross section lies in the cover 4 and whose outlet cross section offset laterally below the heat exchanger and next to the Nozzles 12 is located.

Aus Fig. 2 läßt sich erkennen, daß sich der Wärmetauscher 13 nur über einen Teilbereich 16 der Gesamtlänge 17 des Gehäuses 1 erstreckt sowie daß sich der Zuluftanschluß 6 ebenfalls nur über einen Teilbereich 18 der Gesamtlänge 17 des Gehäuses 1 erstreckt. Die beiden Teilbereiche 16 und 18 sind gleich lang und sich in vertikaler Richtung überdeckend angeordnet. Durch die Stirnseiten 19' und 19" des Gehäuses 1 sind mit dem Wärmetauscher 13 verbundene Anschlußleitungen 20' und 20" geführt. In der Anschlußleitung 20' ist zwischen dem Wärmetauscher 13 und der Stirnseite 19' ein Ventil 21 zur Regulierung der Durchflußmenge durch den Wärmetauscher 13 angeordnet. From Fig. 2 it can be seen that the heat exchanger 13 is only one Section 16 of the total length 17 of the housing 1 extends and that the Supply air connection 6 also only over a partial area 18 of the total length 17 of the housing 1 extends. The two sections 16 and 18 are of equal length and arranged to overlap in the vertical direction. Through the end faces 19 'and 19 "of the housing 1 are connected to the heat exchanger 13 Lead lines 20 'and 20 "out. In the lead line 20' is between the heat exchanger 13 and the end face 19 'a valve 21 for regulating the Flow rate through the heat exchanger 13 is arranged.

In Fig. 3 sind die sich innerhalb eines zu konditionierenden Raumes einstellenden Strömungsverhältnisse dargestellt, wenn der erfindungsgemäße Sockelquellauslaß im Heizfall betrieben wird. Die mit 1 bis 3 K in den Zuluftanschluß 6 eintretende Zuluft verläßt diesen zu ca. zwei Dritteln (Wert durch Wahl des Öffnungsquerschnitts des Lochblechs variierbar) in Richtung des Quelluftraumes 8, um schließlich diesen in waagerechter Richtung bodennah zu verlassen. Das verbleibende Drittel der in den Zuluftanschluß eintretenden Zuluft verläßt letzteren durch die Düsen 12 und strömt direkt auf den Wärmetauscher 13 zu, wird aufgrund dessen hoher Oberflächentemperatur erwärmt und tritt oben durch die Abdeckung 4 in den zu konditionierenden Raum ein. Durch die Düsenanstrahlung des Wärmetauschers 13 ist der Wärmeübergang im Vergleich mit einer freien Konvektion auf ein Mehrfaches gesteigert. Durch die oberhalb des Sockelquellauslasses aufsteigende Warmluft wird einer Kaltluftbewegung zum Rauminneren hin, die aus einem Kaltluftabfall an einem über dem Sockelquellauslaß angeordneten Fenster resultieren könnte, entgegengewirkt. Durch die wandnahe Anordnung des in der Abdeckung 4 befindlichen Eintrittsquerschnitts tritt diese Kaltluft in den Sekundärluftkanal 15 ein und verläßt diesen durch den Austrittsquerschnitt, der sich seitlich versetzt neben den Düsen 12 befindet. In diesem Bereich ist infolge der Düsenausströmung der Druck im Vergleich zum Umgebungsdruck vermindert, wodurch sich eine Induktionswirkung hinsichtlich der im Sekundärluftkanal 15 befindlichen Kaltluft ergibt. Diese induzierte Kaltluft beträgt ca. 25 % der durch die Düsen 12 strömenden Zuluft und bewirkt aufgrund der Temperaturabsenkung der den Wärmetauscher 13 anströmenden Luft eine ganz erheblich gesteigerte Heizleistung im Vergleich mit freier Konvektion. In Fig. 3 are those that arise within a room to be conditioned Flow conditions shown when the base source outlet according to the invention is operated when heating. The 1 to 3 K in the supply air connection 6 incoming air leaves about two thirds of this (value by choosing the Opening cross section of the perforated plate can be varied) in the direction of the source air space 8, in order to finally leave it in a horizontal direction close to the ground. The The remaining third of the incoming air entering the supply air outlet leaves the latter through the nozzles 12 and flows directly to the heat exchanger 13, is due to its high surface temperature warms up and passes through the top Cover 4 in the room to be conditioned. Due to the nozzle radiation of the heat exchanger 13 is the heat transfer in comparison with a free one Convection increased several times over. Through the above the base source outlet rising warm air becomes a cold air movement inside the room down from a drop of cold air arranged at a above the base source outlet Window could result, counteracted. Due to the arrangement close to the wall of the inlet cross section located in the cover 4, this cold air enters into the secondary air duct 15 and leaves it through the outlet cross section, which is laterally offset next to the nozzles 12. In this Due to the nozzle outflow, the area is the pressure compared to the ambient pressure reduced, which has an induction effect with respect to Secondary air duct 15 results in cold air. This induced cold air is about 25% of the supply air flowing through the nozzles 12 and causes due to the lowering of the temperature flowing to the heat exchanger 13 Air a significantly increased heating output compared to free convection.

Über dem erfindungsgemäßen Sockelquellauslaß entsteht so im Heizfall eine aufwärtsgerichtete Warmluftkonvektion wie über einem normalen Heizungskonvektor sowie gleichzeitig eine waagerechte Quellströmung, mit der es möglich ist, dem Raum leicht unterkühlte Zuluft zuzuführen.In the heating case, a thus arises over the base source outlet according to the invention upward hot air convection like over a normal heating convector as well as a horizontal source flow, with which it is possible is to supply slightly cooled supply air to the room.

In Fig. 4 sind die sich einstellenden Strömungsverhältnisse dargestellt, wenn der erfindunsgemäße Sockelquellauslaß im Kühlfall betrieben wird. Auch in diesem Fall strömen ca. zwei Drittel der insgesamt zugeführten Zuluft in den Quelluftraum 8 und verlassen diesen durch den Quelluftaustritt 2 als turbulenzarme waagerechte Quellströmung, die in ca. 10 - 30 cm Höhe zugfrei in den zu konditionierenden Raum strömt.In Fig. 4, the flow conditions are shown when the socket base outlet according to the invention is operated in the cooling case. Also in this In this case, approximately two thirds of the total supply air flow into the source air space 8 and leave this through the source air outlet 2 as low turbulence horizontal source flow, which is draft-free at a height of approx. 10 - 30 cm conditioning space flows.

Das andere Drittel der Zuluft strömt durch die Düsen 12 in den Wärmetauscherraum 11. Sofern überhaupt kein Wärmeübergang von dem Wärmetauscher 13 auf die durch die Düsen 12 einströmende Zuluft stattfindet (Wärmetauscher ist z.B. nicht durchflossen), verläßt die ihn umströmende Luft den Wärmetauscherraum 11 durch die obere Abdeckung 4 mit unveränderter Temperatur, die - wie bereits erwähnt - ca. 1 bis 3 K unterhalb der Raumtemperatur liegt. Trotz der im Moment des Austritts aus der Abdeckung 4 senkrecht nach oben bzw. schräg nach oben gerichteten Strömung fällt dieser Luftstrom nach einer maximalen Höhe von ca. 40 cm wieder ab und legt sich an dem Boden bzw. die dort herrschende Quellluftströmung an. Im Kühlfall wird also der gesamte Zuluftvolumenstrom als Quelllüftung wirksam. Die auch in diesem Fall aufgrund der Düsendurchströmung aus dem Sekundärluftkanal 15 in geringem Maße induzierte Luftmenge ist aufgrund ihres vergleichsweise sehr kleinen Anteils am Gesamtvolumenstrom unbeachtlich. The other third of the supply air flows through the nozzles 12 into the heat exchanger room 11. If there is no heat transfer from the heat exchanger 13 to the incoming air flowing through the nozzles 12 (heat exchanger is e.g. not flowing through), the air flowing around it leaves the heat exchanger space 11 through the top cover 4 with unchanged temperature, which - like already mentioned - is about 1 to 3 K below room temperature. Despite the im Moment of exit from the cover 4 vertically upwards or at an angle upward flow, this airflow drops after a maximum Height of approx. 40 cm again and lies on the floor or the one prevailing there Source air flow. In the cooling case, the total supply air volume flow effective as source ventilation. In this case, too, due to the nozzle flow induced from the secondary air duct 15 to a small extent Air volume is due to its comparatively very small share of the total volume flow irrelevant.

Um die Kühlleistung im Kühlfall weiter zu steigern, ist es auch möglich, den Wärmetauscher 13 mit einem im Vergleich zur Temperatur der Zuluft kälteren Medium zu beaufschlagen. In diesem Fall bewirkt die direkte Düsenanströmung des Wärmetauschers wiederum einen guten Wärmeübergang vom Wärmetauscher 13 auf die diesen umströmende Luft, die daher beim Verlassen des Sockelquellauslasses im Vergleich mit der waagerecht aus dem Quelluftraum 8 austretenden Quelluft eine noch geringere Temperatur aufweist und sich deshalb nach einer noch geringeren Höhe als im undurchströmten Zustand des Wärmetauschers 13 an den Boden bzw. die dort herrschende Quellluftströmung anlegt. Die aus dem Sekundärluftkanal 15 induzierte Raumluft bewirkt in diesem Fall aufgrund ihrer vergleichsweise höheren Temperatur eine größere Temperaturdifferenz am Wärmetauscher 13 und erhöht daher den Wärmeübergang.In order to further increase the cooling capacity in the case of cooling, it is also possible to use the Heat exchanger 13 with a colder compared to the temperature of the supply air To apply medium. In this case, the direct jet flow causes the heat exchanger in turn has a good heat transfer from the heat exchanger 13 on the air flowing around it, which therefore when leaving the base source outlet in comparison with the one emerging horizontally from the source air space 8 Source air has an even lower temperature and therefore after an even lower height than when the heat exchanger is not flowed through 13 applies to the ground or the source air flow prevailing there. The room air induced from the secondary air duct 15 causes in this case due to their comparatively higher temperature, a larger temperature difference on the heat exchanger 13 and therefore increases the heat transfer.

Die Regelung der Heizleistung und damit auch die Änderung von Kühlfall (Heizleistung <0) zu Heizfall (Heizleistung >0) erfolgt rein wasserseitig über die Wahl der Wasservorlauftemperatur und/oder den Wasserdurchfluß. Im erfindungsgemäßen Sockelquellauslaß sind dazu keine beweglichen Teile notwendig, sondern die Änderung der Strömungscharakteristik erfolgt nur über die thermodynamischen Kräfte der gekühlten bzw. erwärmten Luft.The regulation of the heating output and thus also the change of cooling case (heating output <0) for heating (heating output> 0) is done purely on the water side via the selection the water inlet temperature and / or the water flow. In the invention Base source outlet are no moving parts necessary, but the flow characteristics are only changed via the thermodynamic Forces of the cooled or heated air.
