Description
Kältemittel-Luft-Wärmeübertrager angeordnet ist und die beiden Wärmeübertrager durch einen in seiner Strömungsrichtung umkehrbaren Kältemittel-Kreislauf verbunden sind, in den ein Kälte-Kompressor eingeschaltet ist, und daß der Fortluft-Wärmsübertrager '» zugleich als Absorptionsluftwäscher ausgebildet ist.Refrigerant-air heat exchanger is arranged and the two heat exchangers through a reversible refrigerant circuit in its flow direction connected, in which a refrigeration compressor is switched on, and that the exhaust air heat exchanger '» is also designed as an absorption air scrubber.
Mit dieser Anordnung werden eine für das Vorwärmen der Außenluft im Winter verwendete Wärmepumpe, die der Abluft Energie entzieht und im Sommerbetrieb mit umgekehrter Strömungsrichtung als Kühlaggregat verwendet wird, und die energietechnisch vorteilhafte Maßnahme des Besprühens eines Wärmeübertragers zur Erhöhung der Kondensationsleistung gleichzeitig mit der Reinigung der Stalluft zu einer kompakten Anlage verbunden. Dadurch ergibt sich gerätetechnisch ein geringerer Aufwand, und die Sommerluftmenge läßt sich sowohl durch die Umkehr der Wärmepumpe auf Kühlbetrieb wie auch durch das zusätzliche Besprühen des Wärmeübertragers erheblich vermindern, was zu der angestrebten Verringerung der erforderlichen Ventilatorleistung führt.With this arrangement, a heat pump used to preheat the outside air in winter, which extracts energy from the exhaust air and in summer operation with reverse flow direction as a cooling unit is used, and the energetically advantageous measure of spraying a heat exchanger to increase the condensation capacity at the same time as cleaning the house air to one compact system. This results in less expense in terms of equipment, and the The amount of summer air can be reduced by reversing the heat pump to cooling mode as well as by the considerably reduce additional spraying of the heat exchanger, which leads to the desired reduction in the required fan power.
Vorteilhafte Weiterbildungen der Lüftungsanlage sowie Verfahrensweisen zu deren Betrieb sind Gegenstand der Unteransprüche.Advantageous further developments of the ventilation system as well as procedures for their operation are the subject of the subclaims.
Mit Hilfe des Kältemittel-Kompressors wird im Winterbetrieb die Stallwärme aus der Fortluft zurückgewonnen und mit einer Leistungsziffer zwischen 3 und 5 auf die Außenluft übertragen, diese also energiesparend erwärmt. Im Sommerbetrieb wird die angesaugte Außenluft z. B. um ca. 6 K abgekühlt und dann erst dem Stall zugeführt Bei Fortlufttemperaturen von 306 K und Außentemperaturen von 303 K beträgt die Zuluftte;nperatur damit 297 K. Entsprechend der größeren Temperaturdifferenz ist der erforderliche Luftvolumenstrom zur Abfuhr der gleichen Wärmeenergie und bei η Einhaltung der gleichen Ablufttemperatur von 306 K nur ca. 30% des bei der reinen Lüftungsanlage erforderlichen Volumenstromes. Dieser reduzierte Luftvolumenstrom reicht in jedem Falle zur Abfuhr des CO2-Gehaltes und des Wasserdampfes aus. Auch eine Reduzierung um 50% führt bereits zu wertvollen Einsparungen.With the help of the refrigerant compressor, the house heat is recovered from the exhaust air during winter operation and transferred to the outside air with a coefficient of performance between 3 and 5, i.e. it is heated in an energy-saving manner. In summer operation, the outside air drawn in is z. B. cooled by approx. 6 K and only then fed into the stable. At exhaust air temperatures of 306 K and outside temperatures of 303 K, the supply air temperature is 297 K. The air volume flow required to dissipate the same heat energy and if η is adhered to is corresponding to the greater temperature difference the same exhaust air temperature of 306 K only approx. 30% of the volume flow required for a pure ventilation system. This reduced air volume flow is sufficient in any case to remove the CO2 content and the water vapor. Even a 50% reduction leads to valuable savings.
Der zur Temperierung der Stalluft ohnehin in der Lüftungsanlage vorhandene Fortluft-Wärmeübertrager wird in bekannter Weise berieselt oder besprüht. Durch das Benetzen der großen Wärmeübertrager-Oberfläche werden in der Stalluft enthaltene Geruchs- und Staubpartikel gebunden und durch Überschußwasser ausgewaschen. Gleichzeitig ergibt das Besprühen des Wärmeübertragers eine höhere Kondensationsleistung, da je kg verdunstetes Wasser 539 kcal bzw. 630 Wh »Verdunstungskälte« gebunden werden. Damit sinkt bei gegebenem Volumenstrom die Temperaturdifferenz über dem Wärmeübertrager von ca. 15 K auf ca. 10 K.The exhaust air heat exchanger that is already present in the ventilation system to control the temperature of the house air is sprinkled or sprayed in a known manner. By wetting the large heat exchanger surface odor and dust particles contained in the stable air are bound and by excess water washed out. At the same time, spraying the heat exchanger results in a higher condensation performance, since 539 kcal or 630 Wh of "evaporative cold" are bound per kg of evaporated water. This decreases with given volume flow, the temperature difference across the heat exchanger from approx. 15 K to approx. 10 K.
In einer bevorzugten Ausführungsform der Erfindung sind dazu über dem Fortluft-Wärmeübertrager Düsen zur Berieselung seiner Oberfläche und unter dem Fortluft-Wärmeübertrager eine Sammelwanne für abtropfendes Wasser und unter dieser ein Sammelbehälter angeordnet, aus dem eine Schlammpumpe über eine t>o dicht unter dem Flüssigkeitsspiegel mündende Leitung Oberflächenwasser ansaugt und in die Düsen drückt. Konstruktiv ergibt dies eine kompakte Baugruppe, die einfach zu warten und zur Reparatur einfach auszuwechseln ist. Für die Berieselung kann je nach Wasserkosten und gewünschtem Reinigungsgrad nur Frischwasser oder Umlaufwasser benutzt werden.In a preferred embodiment of the invention, nozzles are for this purpose above the exhaust air heat exchanger for sprinkling its surface and under the exhaust air heat exchanger a collecting tray for dripping Water and arranged under this a collecting tank, from which a sludge pump via a t> o The pipe that opens just below the liquid level sucks in surface water and pushes it into the nozzles. In terms of design, this results in a compact assembly that is easy to maintain and easy to replace for repair is. For sprinkling, depending on the water costs and the degree of cleaning required, only Fresh water or circulating water can be used.
Da die Schlammpumpe ai's dem Oberflächenwasser des Sammelbehälters ansaugt werden schwere und große Fremdkörper nicht angesaugt, sondern sinken nach unten ab. Sie werden mit einer periodischen Abschlämmung abgeführt. Dazu ist vorgesehen, daß der Sammelbehälter über ein in seinem Boden angeordnetes Abschlämmventil in einen Güliekanal des Stalles entleerbar istSince the sludge pump sucks in the surface water of the collecting tank ai's heavy and large foreign bodies are not sucked in, but rather sink downwards. You will be using a periodic Drain drained. For this purpose it is provided that the collecting container has a arranged in its bottom Drain valve can be emptied into a Güliekanal of the stable
Weitere konstruktive und betriebliche Einzelheiten sind Gegenstand der übrigen Unteransprüche.Further structural and operational details are the subject of the remaining subclaims.
Durch die Kombination der zentralen Lüftungsanlage des Stalles, ausgelegt für Kühlung bzw. Heizung durch Wärmerückgewinnung mit der zentralen Luftreinigung der Fortluft istBy combining the stable's central ventilation system, designed for cooling or heating Heat recovery with the central air cleaning of the exhaust air is
1. nur eine Lüftungsanlage für beide Zwecke erforderlich; lnvestitions- und Betriebskosten werden getragen von den Kosteneinsparungen durch bessere Futterverwertung bei gleichmäßigeren Stalltemperaturen,1. only one ventilation system required for both purposes; Investment and operating costs are borne by the cost savings through better feed conversion with more uniform feed Stable temperatures,
2. ein Energiegewinn aus dem verdunsteten Wasser am Wärmetauscher vorhanden, der dazu führt, daß diese Wärmeübertragerfläche ca. 50% kleiner sein kann als ohne Berieselung,2. an energy gain from the evaporated water on the heat exchanger, which leads to the fact that this heat exchanger surface can be approx. 50% smaller than without irrigation,
3. ein weiterer Energiegewinn vorhanden, weil die abgegebene Kälteleistung des Kälte-Kompressors je kW Leistungsaufnahme durch die Senkung der Kondensationstemperatur infoige der Berieselung um 10 bis 20% höher ist als ohne Berieselung.3. Another energy gain is available, because the output cooling capacity of the refrigeration compressor per kW power consumption by lowering the condensation temperature infoige of the irrigation 10 to 20% higher than without irrigation.
Im folgenden wird die Erfindung an einem Ausführungsbeispiel und der Zeichnung erläutert. Es zeigt F i g. 1 das Prinzipbild einer Stall-Lüftungsanlage undIn the following the invention is based on an exemplary embodiment and the drawing explained.

Im Winterbetrieb wird die Außenluft dem Wärmeübertrager 1 zugeführt, gemischt mit einem Abluftanteil aus dem Stall 20 über die Abluftöffnung 7 (F i g. 2). Der Ventilator 2 im Außenluftteil 21 fördert die im Winterbetrieb aufgeheizte Luft in den Zuluftkanal 9. Der Wärmeübertrager 1 ist in diesem Fall Kältemittel-Kondensator. In winter operation, the outside air is fed to the heat exchanger 1, mixed with an exhaust air component from the stable 20 via the exhaust air opening 7 (FIG. 2). The fan 2 in the outside air part 21 promotes the im Winter operation heated air into the supply air duct 9. The heat exchanger 1 is in this case a refrigerant condenser.
Ein weiterer Abluftanteil wird aus dem Güllekanal 8 angesaugt und über den Wärmeübertrager 4 im Fortluftteil 22, in diesem Betriebsfall als Kältemittel-Verdampfer geschaltet, abgekühlt und vom Ventilator 5 als Fortluft über Dach geführt. Die Kältemaschine 3, ein Kältemittel-Kompressor, arbeitet in diesem Betriebsrall in Wärmepumpenschaltung.Another proportion of exhaust air is sucked in from the manure channel 8 and via the heat exchanger 4 in the Exhaust air part 22, in this operating case switched as a refrigerant evaporator, cooled and removed by the fan 5 routed as exhaust air over the roof. The refrigeration machine 3, a refrigerant compressor, works in this operating sphere in heat pump circuit.
Im Sommerbetrieb wird der Wirkungssinn der Kältemaschine 3 durch das Umkehrventil 6 getauscht, so daß nunmehr der Wärmeübertrager 1 als Kältemittel-Verdampfer die Außenluft abkühlt. Der Ventilator 2 fördert damit Zuluft in den Stall, die etwa 6 K kälter ist als die Außenluft. Die Abluftöffnung 7 ist in diesem Betriebsfall über die Klappe 10 geschlossen, die Klappe 15 im Außenluftkanal ist geöffnet (Fig.2). Die Abluft wird vollständig z. B. über den Güllekanal 8 angesaugt und über den Fortluft-Wärmeübertrager 4 (als Kältemittel-Kondensator) geführt. Der Ventilator 5 gibt um etwa 10 K überhitzte Fortluft über Dach.In summer operation, the direction of action of the refrigeration machine 3 is swapped by the reversing valve 6, so that now the heat exchanger 1 as a refrigerant evaporator cools the outside air. The fan 2 thus promotes supply air into the house, which is around 6 K colder than the outside air. The exhaust opening 7 is in this Operating case closed via the flap 10, the flap 15 in the outside air duct is open (FIG. 2). The exhaust air is completely z. B. sucked in via the slurry channel 8 and via the exhaust air heat exchanger 4 (as a refrigerant condenser) guided. The fan 5 is about 10 K overheated exhaust air over the roof.
