Abstract

Bauteil zur Wärmerückgewinnung aus Raumabluft (1) dadurch gekennzeichnet, dass es sich aus luftführenden Rohren und einer Kammer bildet, welche von einem Gehäuse umschlossen ist.Component for heat recovery from room exhaust air (1), characterized in that it forms from air-carrying pipes and a chamber which is enclosed by a housing.

Description

Wärmerückgewinnung aus RaumabluftHeat recovery from room exhaust

Die Erfindung betrifft die Rückgewinnung von Abwärme aus Raumabluft und die gleichzeitige Verwendung dieser Energie für die Vorerwärmung der Zuluft in einem kompakten Bauteil.The invention relates to the recovery of waste heat from room exhaust air and the simultaneous use of this energy for the preheating of the supply air in a compact component.

Der aktuelle Stand der Technik der Nutzung von gasförmiger Abwärme wird u. a. in den Schutzschriften DE102005018911 , DE10107637 , DE19750838 , DE19747758 , DE000010058273 , DE000002509038 , DE 000002433496 und DE000002403777 beschrieben. Darin wird jeweils in unterschiedlicher Art und Weise ein Austausch der Energie auf ein anderes Medium herbeigeführt. Das durch Schaffung einer Mischluft oder die Übertragung auf eine Flüssigkeit oder die Einbeziehung eines Wärmepumpen- oder Sorptionskreislaufes oder die Organisation des Wärmeübergangs über Flächengebilde.The current state of the art of the use of gaseous waste heat is, inter alia, in the protection literature DE102005018911 . DE10107637 . DE19750838 . DE19747758 . DE000010058273 . DE000002509038 . DE 000002433496 and DE000002403777 described. In each case in a different way an exchange of energy to another medium is brought about. By creating a mixed air or transfer to a liquid or by incorporating a heat pump or sorption loop or by organizing the heat transfer across sheets.

Es ist Aufgabe der Erfindung, eine Lösung vorzuschlagen, welche der durch einen normgerechten Luftwechsel in Raumen weggeführte warmen Abluft einen hohen Teil der Energie entzieht und diese im getrennten Gegenstromprinzip der kalten Zuluft in einem hohen Maße abgibt und gleichzeitig Mischluft verhindert, welche in der Regel hygienischen Erfordernissen nicht entspricht. Das Austauschverhältnis der Luftströme soll nahe 1:1 sein. Gleichzeitig soll eine Geometrie gefunden werden, welche eine kompakte Bauweise sichert.It is an object of the invention to propose a solution which removes a large part of the energy carried away by a standardized air exchange in rooms warm exhaust air and these in the separate countercurrent principle of the cold supply air to a large extent and simultaneously prevents mixed air, which usually hygienic Requirements does not correspond. The exchange ratio of the air flows should be close to 1: 1. At the same time a geometry is to be found, which ensures a compact design.

Diese Aufgabe wird gelöst indem die absolute Trennung der Zu- und Abluftströme über Rohre innerhalb einer Kammer erfolgt. Damit wird Mischluft verhindert.This task is solved by the absolute separation of the supply and exhaust air flows via pipes within a chamber. This prevents mixed air.

Die kalte Luft wird innen durch die Rohre geführt. Die warme Luft umströmt diese Rohre außen indem ein Gehäuse eine Kammer bildet. Diese getrennten Luftströme werden durch jeweils einen Lüfter im Gegenstrom über Kreuz bewegt.The cold air is led inside through the pipes. The warm air flows around these tubes outside by a housing forms a chamber. These separate air streams are moved crosswise by a fan in countercurrent.

Die Verwendung des Innenvolumens von Rohren für die kalte Luftseite ermöglicht und erzwingt im Falle der Kondensation das gerichtete sofortige Abführen der Wassertropfen und mindert damit den luftseitigen Druckverlust sowie die Wärmeübergangsverluste. Die Rohrdinnendimensionierung für die kalte Luft und die entsprechende Auslegung der Kammer für die warme Luft gewährleistet das für eine optimale Wärmerückgewinnung Volumenverhältnis von 1:1.The use of the internal volume of pipes for the cold air side allows and forces in the case of condensation, the directed immediate removal of the water droplets and thus reduces the air-side pressure loss and the heat transfer losses. The pipe dimensioning for the cold air and the corresponding design of the chamber for the warm air ensures that for optimal heat recovery volume ratio of 1: 1.

Durch die Verwendung von Rohren und deren zylindrische Geometrie wird gewährleistet, dass über die Wandung ein optimales Flächenverhältnis für den Wärmeaustausch gebildet wird. Damit wird eine kompakte Bauweise gesichert. Für die Erhöhung von Turbulenzen können geometrische Oberflächenveränderungen an den Rohrinnen- und/oder -außenwänden eingearbeitet werden.The use of pipes and their cylindrical geometry ensures that an optimal area ratio for the heat exchange is formed via the wall. This ensures a compact design. To increase turbulence, geometric surface changes can be incorporated at the inner and / or outer walls of the pipe.

Die innere Kammer wird durch ein Gehäuse gebildet, welches in einer geeigneten Größe eine verschließbare Reinigungsöffnung enthalten kann.The inner chamber is formed by a housing, which may contain a closable cleaning opening in a suitable size.

Diese Lösung wird im Einzelnen nach 1 beschrieben indem jeweils zwei Lochplatten ein Element zur Luftführung (9) und (10) bilden. Diese Elemente sind im Wesentlichen baugleich. Jedoch werden diese unterschiedlich mit kurzen (12) und längeren Rohren (1) bestückt. Diese Elemente werden von einem Gehäuse (11) umfasst, welches eine Kammer um die Rohre formt. Damit bildet diese Konstruktion einen Baukörper, welcher Zu- und Abluft immer klar voneinander trennt. Die Elemente der Luftführung (9, 10) gewährleisten durch ihren Aufbau gemeinsam mit den getrennten Ansaugstutzen für die kalte Luft (2) und warme Luft (4) ein getrenntes Zu- und Abströmen der Luft. Die Gefahr der Bildung eines luftseitigen Kurzschlusses wird damit ausgeschlossen. Die Luftauslassseiten warm (6) und kalt (5) werden durch eine Fläche mit Rahmen gebildet, welche jeweils einen oder mehrere saugende Lüfter (8) enthält. Die Lüfter werden so geregelt, dass das Austauschvolumen der beiden Luftströme immer im Verhältnis 1:1 besteht und die erforderlichen Luftwechselraten erreicht werden. Das Gehäuse hat an der Unterseite eine Kondensatabführung (7).This solution will be detailed 1 described in each case by two perforated plates an element for air guidance ( 9 ) and ( 10 ) form. These elements are essentially identical. However, these are different with short ( 12 ) and longer pipes ( 1 ) equipped. These elements are covered by a housing ( 11 ), which forms a chamber around the tubes. Thus, this construction forms a building, which always clearly separates incoming and outgoing air. The elements of the air duct ( 9 . 10 ) ensure by their construction together with the separate intake for the cold air ( 2 ) and warm air ( 4 ) a separate inflow and outflow of air. The risk of forming an air-side short circuit is thus excluded. The air outlet sides warm ( 6 ) and cold ( 5 ) are formed by an area with frames, which each have one or more sucking fans ( 8th ) contains. The fans are controlled so that the exchange volume of the two air streams is always 1: 1 and the required air exchange rates are achieved. The housing has a condensate drain at the bottom ( 7 ).

Aus diesem Gebrauchsmuster ergeben sich gegenüber dem bisherigen Stand der Technik folgende Vorteile:

  • – die Verwendung von Rohren sichert ein Optimum an Austauschfläche und gleichzeitig eine kompakte Bauform
  • – die Verwendung von Rohren sichert das ungehinderte Abtropfen von Kondensat und mindert dadurch die Gefahr von stehenden Kondensattropfen, welche den Wärmeübergang mindern und den luftseitigen Druckverlust verringern
  • – die Gestaltung der Zu- und Abluftöffnungen ist nach allen Seiten, je nach baulichem Erfordernis frei wählbar.
This utility model has the following advantages over the prior art:
  • - The use of tubes ensures an optimum exchange surface and at the same time a compact design
  • - The use of pipes ensures the unimpeded drainage of condensate and thereby reduces the risk of standing condensate drops, which reduce the heat transfer and reduce the air-side pressure loss
  • - The design of the inlet and outlet openings is on all sides, depending on the structural requirement freely selectable.
