Description
Windkraftanlagen zur Montage auf Gebäudedächern mit einem orstfest montierten Generator (1), der von strö mender Luft, die über einen Einlaß mit Leitschaufeln zu einer Turbine strömt, angetrieben wird, wobei die Turbinenwelle beidseitig gelagert ist, sind z. B. aus meiner Patentanmeldung DE 38 29 112 bekannt. Das Ge häuse der Windkraftanlage ist dabei in die Windrich tung durch den Luftstrom drehbar, gelagert. -Wind turbines for mounting on building roofs with a fixedly mounted generator ( 1 ), which is driven by streaming air that flows through an inlet with guide vanes to a turbine, the turbine shaft being supported on both sides, for. B. known from my patent application DE 38 29 112. The Ge housing of the wind turbine is rotatable in the wind direction by the air flow, stored. -
Bei der erfindungsgemäßen Konstruktion, ist die Zahl der beweglichen Teile dadurch reduziert worden, daß die Windkraftanlage über ebenfalls ortsfeste, d. h. direkt oder indirekt unbeweglich mit dem Fundament verbundene Ein/Auslässe (5, 6, 7, 8) verfügt, die, je nach Windrichtung, mal Ein- oder mal Auslässe für die Luft sein können. Die Windkraftanlage ist zur optimalen Ausnutzung der Möglichkeiten zur Ausnutzung des durch das Gebäude bedingten Druckgra dienten (Luv-Lee) und der Strömungsenergie der um das Gebäude strömenden Luft, in ihrer Grundfläche (26) so groß wie die zur Verfügung stehende Dachfläche auszulegen. Eine Platte (22), die etwas größer als die Windkraftanlage ist, wird über der eigentlichen Windkraftmaschine horizontal mit einem von der Größe der Anlage und des Hauses abhängendem Abstand über der oberen Abdeckung (25) der Anlage als Witterungs schutz und zur Verbesserung der Strömungseffekte an zubringen. Zur weiteren Erhöhung des Druckgradienten zwischen dem Ein/(Auslaß) (5-8) und dem axialen Auslaß (23) Turbingengehäuse (2) ist die obere Abdeckung (25) so konkav zu wölben, daß der größte Abstand zwischen der Platte (22) und der oberen Abdeckung (25) am axialen Auslaß (23) aus dem Turbinengehäuse (2) erreicht wird. Die den Luftstrom zum Turbinengehäuse (3) bzw. davon in radi aler Richtung wieder ableitenden Luftkanäle (9, 10, 11, 12, 13, 14) sind seitlich durch Leitschaufeln (15-21) begrenzt, die die Luftgeschwindigkeit der einströ menden Luft erhöht. Leitschaufeln dieser Art sind aus der Strömungslehre gut bekannt und müssen empirisch ausgelegt werden. Die zentripetale Verringerung des durchströmten Querschnittes der Luftkanäle (9-14) bis hin zum Turbineneinlaß (z. B. 4) sorgt zusätzlich für eine Erhöhung der Luftgeschwindigkeit. Die Luft strömt durch den Turbineneinlaß (z. B. 4) in das Tur binengehäuse (2) und zwar entsprechend den verlänger ten Mittenachsen (m) der Luftkanäle (9-14) ungefähr tan gential zum imaginären Drehkreis durch die geometri schen Mittelpunkte der Turbinenschaufeln des Turbi nenläufers (3) die um die Turbinenwelle (24) verlaufen. Die die Schaufeln des Turbinenläufers (3) beaufschla gende Luft strömt aufgrund des Luftdruckgradienten, der sich zwischen dem Einlaß und dem Auslaß aufbaut, einerseits aus dem axialen Auslaß (23), andererseits aus dem radialen Auslaß, der den jeweils auf der Lee- Seite liegenden Ein/Auslässen (5, 6, 7, 8) entspricht, und dreht dabei den Turbinenläufer (3), der mit dem Generator (1) fest mechanisch gekoppelt ist, wobei aufgrund der erreichten relativ hohen Turbinendreh zahl eine direkte Kopplung mit dem Generator (1) ohne wirkungsgradverschlechterndes Getriebe möglich ist. Bei entsprechend niedrigen Außentemperaturen ist na türlich auch die erfindungsgemäße Windkraftanlage von Vereisung bedroht. Gegenüber freistehenden Windkraft anlagen besitzt die, auf dem Gebäudedach montierte Anlage noch den Vorteil, durch die Abwärme des Hauses relativ zur Umgebung aufgeheizt zu werden. Die Ver eisung kann also bis zur Temperaturen knapp unter 0°C weitgehend aufgehalten werden. Sollten die Tempera turen jedoch so niedrig sein, daß eine Vereisung der Turbine dennoch zu befürchten steht, ein Betrieb der selben aber erwünscht ist, so kann die Turbine entwe der mit herkömmlichen, die Vereisung verhindernden Mitteln, die z. B. aus dem Flugzeugbau bekannt sind, wie die Aufheizung besonders gefährdeter Teile, ge schützt werden, oder es erfolgt eine Aufheizung der Turbine durch die Durchleitung der warmen Heizungsab gase bzw. der Abluft der Klimaanlage oder sonstiger, z. B. von Industrie- oder Gewerbebetrieben erzeugter, heißer oder warmer Abgase durch die Turbine, wie es in einer Ausführung der erfindungsgemäßen Konstruk tion vorgesehen ist, in der eine Verbindungsleitung (28) vom Schornstein des betreffenden Gebäudes bis zum Turbinengehäuse (2) führt. Bei höheren Tempera turen ist diese Verbindungsleitung (28) durch eine Schornsteinklappe (27) verschlossen; bei niedrigen Temperaturen wird diese Klappe z. B. über einen Elek tromotor thermostatisch gesteuert, geöffnet, wobei der Abgasanteil der in die Turbine eingeleitet wird, über diese Schornsteinklappe (27) so geregelt wird, daß, z. B. schädliche Unterdrücke in der betreffenden Anlagen vermieden werden. Druckabhängige mechanische Steuerungen sind bekannt. Die Ableitung des evtl. entstehenden Kondensates stellt auch kein Problem dar. Es sind hierzu höchstens einige Bohrungen im Turbinengehäuse (2) auf dessen Unterseite vorzusehen. Das Gehäuse (29) der Windkraftanlage wird in Segment bauweise erstellt und ist selbsttragend. Hierdurch ist eine leichtgewichtige kastenkonstruktionsartige Konstruktion möglich. Die Segmente entsprechen den Luftkanälen (z. B. 11) und bestehen aus den Leitschau feln (17, 18) und dem entsprechenden Teil der oberen Abdeckung (25) und der Grundfläche (26) der Windkraft anlage. Das Gehäuse (29) der Windkraftanlage kann aus Metall- oder aus Kunststoff hergestellt werden, oder auch mit, in der Bauwirtschaft bekannten Materi alien bauseitig erstellt werden, wobei auch eine Verwendung vorgefertigter Bauelemente (Segmente z. B.) in Frage kommt. Die reduzierte Zahl der beweglichen Teile und der beweglichen Massen auf ein Minimum, nämlich praktisch nur auf Turbine und Generator, bzw. mit der Turbine verbundene Pumpenanlage, ermöglicht eine relativ leichte Konstruktion des Fundamentes der Gesamtanlage. Die vertikale Turbinenwelle (24), der in der Konstruktion an sich bekannten Turbine, ist in einer Ausführung der erfindungsgemäßen Konstruktion mechanisch direkt, z. B. mit dem Läuferrad einer Pumpe verbunden. Die vertikale Turbinenwelle (24) gestattet diese direkte Verbindung ohne Kraftumlenkung; das hö here Drehzahlniveau und der bessere Massenausgleich gegenüber, z. B. einer Propellerkonstruktion macht ein Getriebe entbehrlich. Hierdurch werden die Herstel lungskosten gering gehalten und ein hoher Wirkungs grad der Anlage ist garantiert.In the construction according to the invention, the number of moving parts has been reduced in that the wind turbine also has fixed inlets / outlets ( 5, 6, 7, 8 ), which are connected directly or indirectly immovably to the foundation and which, depending on the wind direction , can sometimes be inlets or outlets for the air. For optimal use of the possibilities for utilizing the pressure graduation caused by the building (Luv-Lee) and the flow energy of the air flowing around the building, the surface area ( 26 ) of the wind turbine should be as large as the available roof area. A plate ( 22 ), which is slightly larger than the wind turbine, is horizontal over the actual wind turbine with a distance depending on the size of the system and the house above the top cover ( 25 ) of the system as weather protection and to improve the flow effects bring to. To further increase the pressure gradient between the inlet / (outlet) ( 5-8 ) and the axial outlet ( 23 ) of the turbine housing ( 2 ), the upper cover ( 25 ) must be curved so that the greatest distance between the plate ( 22 ) and the upper cover ( 25 ) is reached at the axial outlet ( 23 ) from the turbine housing ( 2 ). The air flow to the turbine housing ( 3 ) or from it in the radial direction deriving air channels ( 9, 10, 11, 12, 13, 14 ) are laterally limited by guide vanes ( 15-21 ), which increases the air velocity of the incoming air . Guide vanes of this type are well known from fluid mechanics and must be designed empirically. The centripetal reduction in the cross-section of the air channels ( 9-14 ) through to the turbine inlet (e.g. 4 ) additionally increases the air speed. The air flows through the turbine inlet (z. B. 4 ) in the Tur binengehäuse ( 2 ) and that corresponding to the elongated center axes (m) of the air channels ( 9-14 ) approximately tan gential to the imaginary turning circle through the geometric center points of the turbine blades of the turbine rotor ( 3 ) which run around the turbine shaft ( 24 ). Due to the air pressure gradient that builds up between the inlet and the outlet, the blades of the turbine runner ( 3 ) act on the one hand from the axial outlet ( 23 ), on the other hand from the radial outlet, which is located on the lee side Inlets / outlets ( 5, 6, 7, 8 ) corresponds to and rotates the turbine rotor ( 3 ), which is mechanically coupled to the generator ( 1 ), whereby due to the relatively high turbine speed achieved, a direct coupling to the generator ( 1 ) is possible without reducing the efficiency. If the outside temperature is correspondingly low, the wind turbine according to the invention is of course also at risk of icing. Compared to free-standing wind turbines, the system installed on the building roof has the advantage of being heated up by the waste heat of the house relative to the surroundings. The icing can therefore be largely stopped up to temperatures just below 0 ° C. However, should the temperatures be so low that icing of the turbine is still to be feared, but operation of the same is desirable, the turbine can either use conventional anti-icing agents, e.g. B. are known from aircraft construction, such as the heating of particularly vulnerable parts, be protected, or there is a heating of the turbine by passing the warm Heizab gases or the exhaust air of the air conditioning system or other, z. B. generated by industrial or commercial, hot or warm exhaust gases from the turbine, as is provided in an embodiment of the construction according to the invention, in which a connecting line ( 28 ) leads from the chimney of the building in question to the turbine housing ( 2 ). At higher temperatures, this connecting line ( 28 ) is closed by a chimney flap ( 27 ); at low temperatures this flap is z. B. thermostatically controlled by an elec tric motor, opened, the proportion of exhaust gas which is introduced into the turbine via this chimney flap ( 27 ) is regulated so that, for. B. harmful negative pressures in the systems concerned can be avoided. Pressure-dependent mechanical controls are known. The drainage of the condensate that may arise is also not a problem. A maximum of a few holes in the turbine housing ( 2 ) must be provided on the underside thereof. The housing ( 29 ) of the wind turbine is constructed in segments and is self-supporting. This enables a lightweight, box-type construction. The segments correspond to the air ducts (e.g. 11 ) and consist of the guide vanes ( 17, 18 ) and the corresponding part of the upper cover ( 25 ) and the base area ( 26 ) of the wind power plant. The housing ( 29 ) of the wind turbine can be made of metal or plastic, or can be created on-site with materials known in the construction industry, with the use of prefabricated components (segments, for example) also being considered. The reduced number of moving parts and moving masses to a minimum, namely practically only on the turbine and generator, or pump system connected to the turbine, enables a relatively light construction of the foundation of the overall system. The vertical turbine shaft ( 24 ), the turbine known per se in the construction, is mechanically direct in one embodiment of the construction according to the invention, e.g. B. connected to the impeller of a pump. The vertical turbine shaft ( 24 ) allows this direct connection without force redirection; the higher speed level and the better mass balance compared to e.g. B. a propeller design makes a transmission unnecessary. As a result, the manufacturing costs are kept low and a high efficiency of the system is guaranteed.
