Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Wärmerückgewinnung von in Luft befindlicher Wärmeenergie durch einen Rotationswärmeübertrager mit einem sich drehenden Wärmerad, das in einem Fortluft- und einem Zuluftkanal angeordnet ist, deren Luftströme das Wärmerad durchströmen, wobei ein Luftstrom aufgewärmt und ein Luftstrom abgekühlt wird.The The invention relates to a device for heat recovery of in-air Thermal energy by a rotary heat exchanger with a rotating heat wheel, which is arranged in an exhaust air and a supply air duct, whose air flows through the heat wheel, wherein a stream of air warmed up and a stream of air is cooled.
Es ist bekannt, die Wärmeenergie der aus einem Raum insbesondere einem Wohnraum austretenden Abluft in einer Speichermasse zu speichern und an die Zuluft (Außenluft) abzugeben. Hierzu werden Regeneratoren wie Rotationswärmeübertrager (Rotationswärmetauscher) verwendet, die ein Wärmerad aufweisen, das mit der Speichermasse gefüllt ist. Bei diesen bekannten Rotationswärmeübertragern hat es sich gezeigt, dass in erheblichem Maße Leckluft besteht, die im Falle belasteter Abluft unerwünscht ist.It is known, the heat energy the exiting from a room in particular a living room exhaust air to store in a storage mass and to the supply air (outside air) leave. For this purpose, regenerators such as rotary heat exchangers (rotary heat exchangers) used a heat wheel have, which is filled with the storage mass. In these known Rotationswärmeübertragern It has been shown that there is a significant amount of air leakage in the air Trapped exhaust air undesirable is.
Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art so zu verbessern, dass bei einfacher Konstruktion und Herstellung die Leckluft auf ein Minimum reduziert ist.task The invention is a device of the type mentioned to improve so that with simple design and manufacture the leakage air is reduced to a minimum.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Wärmerad in eine gerade Anzahl von Kammern bildenden Sektoren mit geschlossenen Trennwänden unterteilt ist und dass die an den Sektoren angrenzenden Fortluft- und Zuluftkanäle bei Stillstand des Wärmerades jeweils stets mit der Hälfte der sektorenförmigen Kammern verbunden sind.These Task is inventively characterized solved, that the heat wheel in an even number of chambers forming sectors with closed partitions is divided and that adjacent to the sectors exhaust air and supply air ducts at standstill of the heat wheel always always with half the sectoral Chambers are connected.
Hierdurch ist dafür gesorgt, dass die am Wärmerad anliegenden Anschlussflächen der Fortluft- und Zuluftkanäle bei Stillstand des Wärmerades exakt mit den sektorenförmigen Kammern des Wärmerades fluchten, so dass Leckluft nicht entstehen kann. Hierbei sind die am Wärmerad anliegenden Anschlussöffnungsflächen als Zuluftöffnung und Abluftöffnung der Fortluft- und Zuluftkanäle in ihrem Querschnitt halbkreisförmig und entsprechen damit in ihrer Größe und Form einer Hälfte aller Wärmeradkammern.hereby is for that taken care of that at the heat wheel adjacent connection surfaces the exhaust air and supply air ducts at standstill of the heat wheel exactly with the sectoral Chambers of the heat wheel aligned, so that leakage air can not arise. Here are the at the heat wheel adjacent terminal opening surfaces as air intake opening and exhaust port the exhaust air and supply air ducts semicircular in cross-section and thus correspond in their size and shape to a half of all Wärmeradkammern.
Von Bedeutung ist, dass die Stirnseiten der Trennwände jeweils eine Dichtung aufweisen, die gegenüber der Kanaltrennwand abdichtet, so dass auch hierdurch Leckluft verhindert wird.From Meaning is that the end faces of the partition walls each have a seal, the opposite the channel partition seals, so that also prevents leakage air becomes.
Von Vorteil ist, wenn die Kammern zur losen Befüllung mit dem Speichermaterial durch Gitter oder Lochbleche an den Stirnseiten verschlossen sind. Vorzugsweise weist das Wärmerad für jede Kammer eine Beladeöffnung, für ein ein- oder mehrmaliges Beladen auf. Hierbei kann die Beladeöffnung in der Umfangsfläche des Wärmerades angeordnet sein.From Advantage is when the chambers for loose filling with the storage material are closed by grids or perforated plates on the front sides. Preferably has the heat wheel for every Chamber a loading opening, for a one or more loading on. Here, the loading opening in the peripheral surface of the heat wheel be arranged.
Eine einfache und komfortable Regelung ist erreichbar, wenn das Wärmerad in einem im Querschnitt rechteckförmigen insbesondere quadratischen Raum einliegt und die Eckräume neben dem Wärmerad die Bypasskanäle aufweisen insbesondere bilden. Hierzu weisen zum Steuern insbesondere Regeln der Bypasskanäle diese Klappenventile auf. Hierbei weist der Eckraum eine Klappenmechanik auf, der die Luftverteilung Bypass/Rad steuert.A easy and comfortable control is achievable when the heat wheel in a rectangular in cross-section especially square room rests and the corner rooms next to the heat wheel the bypass channels in particular, form. For this purpose have to control particular rules the bypass channels these flapper valves on. Here, the corner space has a flap mechanism, which controls the air distribution by-pass / wheel.
Die Nutzung der Eckräume der Bypasskanäle erlaubt die maximale Radgröße für die gewählten Kanäle und damit minimierte Druckverluste ohne auf den Bypass zu verzichten.The Use of the corner rooms the bypass channels allows the maximum wheel size for the selected channels and thus Minimized pressure loss without sacrificing the bypass.
Die Vorrichtung arbeitet besonders ökonomisch, wenn das zyklische schnelle Drehen des Wärmerades durch einen Federmechanismus erfolgt, welcher durch einen Elektromotor aufgezogen wird. Ferner wird hierzu vorgeschlagen, dass das Abbremsen des Wärmerades bei Einführung der Segmente den Federmechanismus teilweise wieder aufzieht zur Energierückgewinnung und Minderung der Kräfte der Entschleunigung. Schließlich ist von Vorteil, wenn zum Minimieren der Leckluft der Sektoren- bzw. Kammerwechsel schnellstmöglich erfolgt.The Device works very economically, when the cyclic fast turning of the heat wheel by a spring mechanism takes place, which is mounted by an electric motor. Further is proposed for this purpose that the braking of the heat wheel at introduction the segments partially reboots the spring mechanism for energy recovery and reducing the forces the deceleration. After all is advantageous if, to minimize the leakage air, the sector or changing the chamber as quickly as possible he follows.
Besonders vorteilhaft ist es, wenn die Kammern mit Spänen, Schaum und/oder Drahtgewebe aus Metall insbesondere aus Aluminium oder Kupfer gefüllt sind.Especially It is advantageous if the chambers with chips, foam and / or wire mesh Metal in particular made of aluminum or copper are filled.
