Abstract
Description
Die Erfindung betrifft einen Unterflurkonvektor mit einem im Konvektorgehäuse angeordneten Wärmetauscher und einem in Strömungsrichtung hinter dem Wärmetauscher angeordneten Gebläse, durch das die den Wärmetauscher gekühlte oder erwärmte Sekundärluft insbesondere Raumluft in den Raum blasbar ist.The The invention relates to a underfloor convector with a arranged in the convector housing heat exchangers and one in the flow direction behind the heat exchanger arranged blower, through which the the heat exchanger chilled or heated secondary air in particular Room air is blown into the room.
Zum Kühlen von Räumen ist es bekannt, Unterflurkonvektoren zu verwenden, die die Raumluft ansaugen, durch einen Wärmetauscher führen und danach wieder in den Raum abgeben. Übliche, am Markt erhältliche Geräte, verwenden dazu ein Quellluftsystem, welches die Luft bodennah austreten lässt. Bei diesen Systemen kann es aufgrund der geringen Luftaustrittsgeschwindigkeiten und niedrigen Luftaustrittstemperaturen zu Zugerscheinungen im Bodenbereich kommen, so dass ein Kaltluftsee entstehen kann. Ein weiterer Nachteil der Quellluftsysteme ist, dass der Quellluftstrom durch Mobiliar nicht blockiert werden darf. Ein Kühldeckenbetrieb wäre möglich, jedoch wird dabei das Temperaturprofil des Raumes in Kombination mit dem Quellluftsystem deutlich beeinträchtigt und die thermische Behaglichkeit nimmt ab. Bei Beachtung der thermischen Behaglichkeit liegt die maximale Kühlleistung des Quellluftsystems lediglich bei 25 W/m2. Auch ist mit diesem System nur der Kühlfall realisierbar, nicht jedoch der Heizbetrieb, da aufgrund des geringen Austrittsimpulses die warme Luft nur gerätenah austritt und durch die Auftriebskräfte zur Decke steigt, ohne sich mit der Raumluft zu vermischen.For cooling rooms, it is known to use underfloor convectors, which suck in the room air, lead through a heat exchanger and then return to the room. Conventional devices available on the market use a source air system that lets the air escape near the ground. In these systems, due to the low air outlet velocities and low air outlet temperatures, drafts may occur in the floor area, so that a cold air lake can arise. Another disadvantage of the source air systems is that the source air flow may not be blocked by furniture. A cooling ceiling operation would be possible, however, the temperature profile of the room in combination with the source air system is significantly affected and the thermal comfort decreases. When considering the thermal comfort, the maximum cooling capacity of the source air system is only 25 W / m 2 . Also, with this system, only the cooling case can be realized, but not the heating operation, since due to the low exit pulse, the warm air leaking device-only and rises by the buoyancy forces to the ceiling, without mixing with the room air.
Aufgabe der Erfindung ist es, einen Unterflurkonvektor der eingangs genannten Art so zu verbessern, dass bei einfacher Konstruktion und Handhabung zusätzlich zur Raumlufterwärmung und/oder -kühlung Frischluft in den Raum in der jeweils gewünschten Menge einbringbar ist, wobei eine schnelle und gründliche Durchmischung der austretenden Luft und der Raumluft erreicht wird, ohne Zugerscheinungen auftreten zu lassen.task The invention is an underfloor convector of the aforementioned Art to improve so that with simple design and handling additionally for room air heating and / or cooling Fresh air into the room in the respectively desired amount can be introduced, being a quick and thorough Mixing of the exiting air and the room air is achieved to appear without drafts.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass direkt neben dem Gebläseluftauslass ein zweiter Luftauslass angeordnet ist, dessen Luftausströmrichtung im wesentlichen parallel zur Luftausströmrichtung des Gebläses ist, und dass der zweite Luftauslass mit einer Primärluftquelle insbesondere einer Frischluftquelle verbindbar ist.These Task is inventively characterized solved, that right next to the fan air outlet a second air outlet is arranged, the air outflow direction is substantially parallel to the air outflow of the blower, and that the second air outlet with a primary air source in particular a Fresh air source is connectable.
Hierdurch wird das Prinzip der Mischlüftung geschaffen. Durch die hohen Luftaustrittsgeschwindigkeiten wird die Sekundärluft (Raumluft) mitgerissen und vermischt sich. Dadurch entsteht ein gleichmäßiges Temperaturprofil im Raum und ein behagliches Raumklima. Durch Ausnutzung des Coanda-Effektes wird die Luft am Aufenthaltsbereich vorbeigeführt, wodurch es nicht zu Zugerscheinungen kommen kann.hereby the principle of mixed ventilation is created. Due to the high air outlet speeds, the secondary air (room air) entrained and mixes. This creates a uniform temperature profile in the room and a comfortable room climate. By exploiting the Coanda effect The air is passed by the area of residence, which does not cause drafts can come.
Es werden hohe Luftaustrittsgeschwindigkeiten erreicht, welche für eine effiziente Mischlüftung sorgen. Die Nutzung des Coanda-Effektes ermöglicht es, den Strahl an der Wand und Decke entlang zu führen, so dass keine Zugerscheinungen im Aufenthaltsbereich entstehen können. Ein behagliches Raumklima wird so gewährleistet. Ferner ist aufgrund geringer Geräusche ein akustischer Komfort gegeben.It high air outlet velocities are achieved, which are efficient Provide mixing ventilation. The use of the Coanda effect makes it possible to use the beam at the To lead along wall and ceiling so that no drafts in the common area can arise. One comfortable indoor climate is guaranteed. Further, it is due to lower Sounds given an acoustic comfort.
Problemlos lässt sich dieses System mit einer Kühldecke kombinieren und sowohl Kühlen als auch Heizen können realisiert werden. Die Kühlleistung ist mit maximal 60 W/m2 dreifach höher als bei gängigen Systemen.This system can be easily combined with a cooling ceiling and both cooling and heating can be realized. The cooling capacity is three times higher with a maximum of 60 W / m 2 than with conventional systems.
Vorzugsweise wird vorgeschlagen, dass der erste und zweite Luftauslass nebeneinander in der Oberseite des Konvektors angeordnet sind.Preferably It is suggested that the first and second air outlets side by side are arranged in the top of the convector.
Besonders vorteilhaft ist es, wenn der zweite Luftauslass das offene Ende eines Luftkanals bildet, der durch das Konvektorgehäuse verläuft. Damit werden Primärluft und Sekundärluft separat bis zum Luftaustritt geführt, so dass von einem „Dual-System" gesprochen werden kann. Durch Trennung der beiden Luftströme werden ferner Energieverluste vermieden. Hierdurch ist auch ein getrennter Betrieb von reinem Umluftbetrieb oder Primärluftbetrieb jederzeit möglich.Especially It is advantageous if the second air outlet is the open end an air channel which passes through the convector housing. With that primary air and secondary air separately led to the air outlet, so to speak of a "dual system" can. By separating the two air streams are also energy losses avoided. This is also a separate operation of pure Recirculation mode or primary air mode anytime possible.
Eine besonders einfache und höchst effektive Konstruktion ist gegeben, wenn der Luftkanal entlang einer Konvektoraußenwand und/oder entlang dem Konvektorboden verläuft. Auch kann hierzu der Konvektor einen doppelten Boden aufweisen und der Zwischenraum zwischen den zwei Böden den Luftkanal für die Primärluft bilden.A particularly simple and most Effective construction is given when the air duct is along a Konvektoraußenwand and / or runs along the convector floor. Also, this can be the convector have a double bottom and the space between the two floors the air duct for the primary air form.
Eine besonders einfache Konstruktion bei widerstandsarmer Luftführung wird erreicht, wenn innerhalb des Konvektorgehäuses eine Wanne in einem Abstand zum Gehäuseboden angeordnet ist, und dass im Abstandsraum die Primärluft führbar ist. Alternativ oder zusätzlich wird vorgeschlagen, dass innerhalb des Konvektorgehäuses eine Wanne in einem Abstand zu mindestens einer Gehäuseseitenwand angeordnet ist, und dass im Abstandsraum die Primärluft führbar ist. Besonders vorteilhaft ist es, wenn die Wanne nach oben aus dem Gehäuse herausnehmbar ist.A particularly simple construction with low-resistance air flow achieved when within the convector housing a trough at a distance to the case back is arranged, and that in the distance space, the primary air is feasible. alternative or additionally it is suggested that within the convector housing a Trough is arranged at a distance from at least one housing side wall, and that in the distance space, the primary air is feasible. Especially advantageous it is when the tub is removable from the top of the housing.
Vorzugsweise ist das Gebläse ein Radialventilator ist, dessen Laufrad eine größere axiale Länge aufweist als der Laufraddurchmesser.Preferably is the fan a centrifugal fan whose impeller has a greater axial length as the impeller diameter.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einem senkrechten Querschnitt dargestellt und wird im Folgenden näher beschrieben.One embodiment the invention is in the drawing in a vertical cross-section and will be described in more detail below.
