Description

Die beanspruchte Erfindung bezieht sich auf die Lüftung der Kuhställe und ist auf der Erfahrung der natürlichen Lüftungssysteme mit dem Verbrauch der inneren Wärmeabgabe der Haustiere für die Erwärmung der Zuluft während der kalten Jahreszeitperiode gegründet. Aus der Druckschrift US 1263833 A ist ein Lüftungssystem u. a. für Stallgebäude bekannt, bei dem die Zuluft- und Abluftkanäle mit einem ‚Rohr in Rohr’ System mit konzentrischen Kreisen oder mit einem ‚Rechteck in Rechteck’ System ausgestattet sind. Es ist dort keine Möglichkeit vorgesehen das Kondensat abzuführen.The claimed invention relates to the ventilation of the cowsheds and is based on the experience of the natural ventilation systems with the consumption of the domestic heat release of the domestic animals for the heating of the supply air during the cold season. From the publication US 1263833 A For example, a ventilation system is known for stable buildings, where the supply air and exhaust air ducts are equipped with a 'pipe in pipe' system with concentric circles or with a 'rectangle in rectangle' system. There is no possibility to remove the condensate.

Aus der Druckschrift SU 1295161 A1 ist eine Vorrichtung für eine natürliche ventilatorlose Lüftung eines Kuhstalls bekannt, die mit guten Ergebnissen getestet wurde. Trotzdem hat diese Vorrichtung folgende Nachteile:

  • – die Wärmeaustauschfläche zwischen den warmen und kalten Luftströmen ist nur durch die Höhe der Wand, neben der sie angeordnet ist, beschränkt;
  • – die Windenergie wird für den Zustrom durch die Anlage nicht benutzt;
  • – die obere Zone des Kuhstalls wird nicht gelüftet. Daraus ergibt sich die Aufgabe diese Nachteile zu vermeiden.
From the publication SU 1295161 A1 is a device for a natural fanless ventilation of a cow stable known, which has been tested with good results. Nevertheless, this device has the following disadvantages:
  • - The heat exchange surface between the hot and cold air flows is limited only by the height of the wall, next to which it is arranged;
  • - the wind energy is not used for the influx through the plant;
  • - the upper zone of the cowshed is not ventilated. This results in the task of avoiding these disadvantages.

Im vorgeschlagenen System werden diese Nachteile dadurch vermieden, dass:

  • – die Zu- und Abluftkanäle im System „Rohr in Rohr” mit einer trapezförmigen Zwischenwand verbunden sind;
  • – die Zu- und Abluftkanäle an den Wänden und Dächern des Kuhstalls entlang angeordnet sind;
  • – der Zuluftkanal eine zweiseitige Zuluftkamera mit zwei eingebauten Zuerwärmern hat.
In the proposed system, these disadvantages are avoided by:
  • - The supply and exhaust air ducts in the system "pipe in tube" are connected to a trapezoidal partition wall;
  • - The supply and exhaust air ducts are arranged along the walls and roofs of the cowshed along;
  • - The supply air duct has a two-sided supply air camera with two built-in heaters.

Das Schema dieses Systems ist in der 1 dargestellt. Das Hauptdetail dieses Systems ist ein gemeinsamer Zu- und Abluftkanal. In dem gemeinsamen Kanal sind Zuluftkanal (1) und Abluftkanal (2) durch eine trapezförmige Zwischenwand (3) getrennt. Der gemeinsame Kanal hat einen unteren Deckel (4) mit zwei Kondesatrillen (5). The scheme of this system is in the 1 shown. The main detail of this system is a common supply and exhaust duct. In the common channel are supply air duct ( 1 ) and exhaust duct ( 2 ) by a trapezoidal partition ( 3 ) separated. The common channel has a lower lid ( 4 ) with two Kondesatrillen ( 5 ).

Die vereinigten Kanäle sind von beiden Seiten des Kuhstalls entlang an Wänden und Dach angelegt worden, und mit einem Deflector (6) an der Spitze des Dachs vereinigt. Der Deflector (6) hat die Form zweier Pyramidenstümpfe, die mit den Fundamenten vereinigt sind.The united canals have been laid along walls and roofs from both sides of the cowshed, and with a deflector ( 6 ) united at the top of the roof. The deflector ( 6 ) has the form of two truncated pyramids, which are united with the foundations.

Jeder Zuluftkanal (1) ist unten von beiden Seiten durch Öffnungen (7) mit zwei Zuluftkameras (8) verbunden, in denen zwei Zuerwärmer (9) angeordnet sind. Jede Kamera (8) hat Zuluftauslässe (10). Abluftkanäle (2) haben neben dem Boden die Abluftöffnungen (11). Neben dem Deflector (6) haben die Zuluftkanäle (1) Öffnungen (12) für die Außenluftaufnahme, und die Abluftkanäle (2) haben den oberen Abluftspalt (13).Each supply air duct ( 1 ) is at the bottom from both sides through openings ( 7 ) with two supply air cameras ( 8th ), in which two heaters ( 9 ) are arranged. Every camera ( 8th ) has supply air outlets ( 10 ). Exhaust ducts ( 2 ) have the exhaust air openings ( 11 ). Next to the deflector ( 6 ) have the supply air ducts ( 1 ) Openings ( 12 ) for the outside air intake, and the exhaust ducts ( 2 ) have the upper exhaust air gap ( 13 ).

Das Lüftungssystem funktioniert im Winter folgendermaßen.The ventilation system works in the winter as follows.

Der Winddruck „presst” die Außenluft in die Öffnungen (12) ”ein” und diese Luft strömt durch die Zuluftkanäle (1) nach unten. Von der oben geöffneten Seite des Deflectors (6) bildet sich eine so genannte „Zone des airodynamischen Schattens” – eine Tiefdruckzone. Von ihrer Wirkung zieht sich die innere Luft aus der Betriebszone durch die Abluftöffnungen (11) in die Abluftkanäle (2) und bewegt sich durch diese Kanäle nach oben. In dieser gegenströmigen Bewegung kommt es zu einem intensiven Wärmeaustausch zwischen der warmen und feuchten Abluft und der kalten Außenluft durch die trapezförmige Zwischenwand (3) und den Wänden des Zuluftkanals (1). Die Kondensation des Dunstes der feuchten Abluft intensiviert den Wärmeaustausch. Das Kondensathäutchen fließt in die Kondensatrillen (5) und danach auf den Betriebsboden und in die Mistkanäle.The wind pressure "presses" the outside air into the openings ( 12 ) "And" this air flows through the supply air ducts ( 1 ) downward. From the top of the deflector ( 6 ) forms a so-called "zone of the airodynamic shadow" - a low pressure zone. From their effect, the internal air from the operating zone pulls through the exhaust air openings ( 11 ) in the exhaust ducts ( 2 ) and moves up through these channels. In this countercurrent movement, there is an intense heat exchange between the warm and moist exhaust air and the cold outside air through the trapezoidal partition ( 3 ) and the walls of the supply air duct ( 1 ). The condensation of the mist of the moist exhaust air intensifies the heat exchange. The condensation droplet flows into the condensate ( 5 ) and then on the operating floor and in the manure channels.

Die erwärmte Außenluft zieht weiter durch die Öffnungen (7) in zwei Zuluftkameras (8), wo sie eine höhere Zulufttemperatur mit Hilfe der Zuerwärmern (9) erfährt und durch Zuluftauslässe (10) in die Betriebszone ausgeht. The heated outside air continues through the openings ( 7 ) in two supply air cameras ( 8th ), where they have a higher supply air temperature with the help of the warmers ( 9 ) and by supply air outlets ( 10 ) into the operating zone.

Bei windlosem Wetter funktioniert das Lüftungssystem unter dem Gravitationsdruck den die Zuerwärmer (9) schaffen. Im Sommer wirkt das Lüftungssystem vom Wind ohne Wärmeaustausch. Außerdem wird der Stall durch das offene Fenster gelüftet.In windless weather, the ventilation system works under the gravitational pressure that the heaters ( 9 ) create. In summer the ventilation system acts on the wind without heat exchange. In addition, the stable is ventilated through the open window.
