Description

Beschreibung description
Fahrzeug zur Personenebeförderung vehicle for passenger transport
Die Erfindung bezieht sich auf ein Fahrzeug zur Personenbe förderung, mit einem Galley-Bereich, in dem wenigstens eine Einbaukomponente angeordnet ist, die lokal Abwärme erzeugt, und mit einem Kälteaggregat, das einen Kondensator zur Ent- wärmung eines Kältemittels des Kälteaggregats aufweist, wobei eine Kondensator-Lüfter zur Beaufschlagung des Kondensators mit Abluft aus dem Galley-Bereichs des Fahrzeugs vorgesehen ist. The invention relates to a vehicle for passenger transport, with a galley area in which at least one built-in component is arranged that generates waste heat locally, and with a refrigeration unit that has a condenser for cooling a refrigerant of the refrigeration unit, wherein a Condenser fan is provided for loading the condenser with exhaust air from the galley area of the vehicle.
Solche Fahrzeuge, die zum Catering von Fahrgästen mit einer Bordküche (Galley) ausgestattet sind, sind beispielsweise bei Schienenfahrzeugen als Restaurantwagen bekannt. Jedoch bieten inzwischen auch verschiedene Fluggesellschaften ein gehobenes Catering für Fluggäste an, so dass die betreffenden Flugzeuge ebenfalls mit einer Bordküche ausgestattet sind. Gleiches gilt auch für Wasserfahrzeuge wie Kreuzfahrtschiffe. Such vehicles, which are equipped with a galley for catering passengers, are known, for example, in rail vehicles as restaurant cars. However, various airlines now also offer upscale catering for passengers, so that the aircraft in question are also equipped with a galley. The same applies to watercraft such as cruise ships.
Beispielsweise Restaurantwagen stellen eine besonders hohe Anforderung an deren Klimatisierung dar. Denn zum einen sind in den für Fahrgäste vorgesehenen Komfortbereichen die zuläs sigen Temperaturen, bestimmt durch einschlägige Normen, ein zuhalten, während zum anderen die Gerüche aus dem Galley- Bereich nicht im Innenraum des Fahrzeugs verteilt werden dür fen. Eine solche Galley-Küche besitzt typischerweise Abwärme quellen, wie eine Dunstabzugshaube (Steamer), Spülmaschine, Kaffeemaschine usw. Solche Einbaukomponenten eines Galley- Bereichs eines Fahrzeugs erzeugen lokal Abwärme, welche einer Klimatisierung eines Innenraums des betreffenden Fahrzeugs erschweren . Restaurant cars, for example, place particularly high demands on their air conditioning. On the one hand, the permissible temperatures, determined by relevant standards, must be observed in the comfort areas provided for passengers, while on the other hand, the smells from the galley area are not in the interior of the vehicle may be distributed. Such a galley kitchen typically has waste heat sources, such as an extractor hood (steamer), dishwasher, coffee machine, etc. Such built-in components of a galley area of a vehicle generate waste heat locally, which makes it difficult to air-condition the interior of the vehicle in question.
Insbesondere bei Schienenfahrzeugen ist der Galley-Bereich ebenfalls mit einem Kälteaggregat ausgestattet. Bei diesem Kälteaggregat wird an dessen Kondensator ein Kältemittel des Kälteaggregats entwärmt. Der dazu verwendete Abluftstrom aus dem Galley-Bereich entnimmt dem Kältemittel Wärme. Der Luft strom, der den Kondensator des Kälteaggregats passiert hat, wird teils zurück in das Fahrzeug und teils in eine Fortluft geführt und an eine Umgebung des Fahrzeugs abgegeben. In rail vehicles in particular, the galley area is also equipped with a cooling unit. In this refrigeration unit, a refrigerant of the refrigeration unit is cooled at its condenser. The exhaust air flow used for this the galley area extracts heat from the refrigerant. The air flow that has passed the condenser of the refrigeration unit is partly fed back into the vehicle and partly into an exhaust air and released to an environment of the vehicle.
Was eine Abluft, insbesondere der Dunstabzugshaube, angeht, so wird diese gesondert ebenfalls über die Fortluft nach au ßerhalb des Fahrzeugs abgeführt. As far as exhaust air, in particular from the extractor hood, is concerned, this is also discharged separately via the exhaust air to the outside of the vehicle.
Grundsätzlich wird bisher versucht, so viel Abwärme aus den lokal Abwärme erzeugenden Einbaukomponenten im Galley-Bereich wie möglich in die Fortluft zu führen, damit eine zusätzliche Erwärmung insbesondere der Komfortbereiche des Fahrzeugs ver mieden wird. Dies hat jedoch den Nachteil, dass mit Erhöhung der Fortluftmenge auch mehr Frischluft durch das Kälteaggre gat des Fahrzeugs aufbereitet werden muss. Da jedoch die Käl teleistung des Kälteaggregats begrenzt ist, besteht die Ge fahr, dass die per Norm vorgeschriebenen Innenraumtemperatu ren nicht mehr erreicht werden können. Attempts have hitherto been made in principle to conduct as much waste heat as possible from the built-in components in the galley area that generate local waste heat into the exhaust air, so that additional heating, particularly in the comfort areas of the vehicle, is avoided. However, this has the disadvantage that as the volume of exhaust air increases, more fresh air also has to be processed by the vehicle's refrigeration unit. However, since the cooling capacity of the refrigeration unit is limited, there is a risk that the interior temperatures specified by the standard can no longer be achieved.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Fahrzeug der eingangs genannten Art derart weiterzuentwi ckeln, dass die erforderliche Leistung des Kälteaggregats zur Klimatisierung des Fahrzeugs vermindert ist. Proceeding from this, the invention is based on the object of further developing a vehicle of the type mentioned at the outset in such a way that the required output of the refrigeration unit for air conditioning the vehicle is reduced.
Diese Aufgabe wird bei dem eingangs genannten Fahrzeug dadurch gelöst, dass der wenigstens eine Einbaukomponente ein Luftkanal zum Absaugen von lokal an der wenigstens einen Ein baukomponente erwärmte Abluft zugeordnet ist, wobei diese Ab luft mittels des Luftkanals zu einer Eingangsseite des Kon densators des Kälteaggregats geführt ist. This object is achieved in the vehicle mentioned at the outset in that the at least one built-in component is assigned an air duct for extracting exhaust air heated locally at the at least one built-in component, this exhaust air being routed to an input side of the condenser of the refrigeration unit by means of the air duct .
Damit wird eine Fortluft einer lokal Abwärme erzeugenden Ein baukomponente im Galley-Bereich, beispielsweise eine Dunstab zugshaube, nicht separat in die Fortluft geführt, sondern der Fortluft des Kondensators des Kälteaggregats vorgeschaltet. Damit wird das Kälteaggregat erheblich entlastet. Es ist näm lich möglich, dass der Kondensator-Lüfter die zusammengeführ- te Abluft aus dem Galley-Bereich und von der lokalen Abwärme erzeugenden Komponente zur Entwärmung des Kältemittels des Kälteaggregats an dem Kondensator vorbei fördert. Der Begriff „Kondensator" schließt im Sinne dieser Beschreibung auch ei nen Gaskühler ein. Im Vergleich zu einer gesonderten Fort luftführung für die Einbaukomponente entfällt der Fortluft strom, der allein von der Einbaukomponente herrührt. Demge genüber ändert sich der Fortluftstrom am Kondensator des Käl teaggregats nicht. Somit wird zwar die Abwärme, die von der Einbaukomponente stammt, abgeführt, der Gesamt-Fortluftstrom jedoch vermindert. Dies hat den Vorteil, dass keine erhöhte Kälteleistung für eine Frischluftaufbereitung durch das Käl teaggregat erforderlich ist. Da beispielsweise eine Dunstab zugshaube („Steamer") nur sequenziell betrieben wird, ergeben sich keine erhöhten Anforderungen an den Kondensator. This means that exhaust air from a building component in the galley area that produces local waste heat, for example a fume hood, is not fed separately into the exhaust air, but is connected upstream of the exhaust air from the condenser of the refrigeration unit. This relieves the refrigeration unit considerably. It is namely possible that the condenser fan blows the combined te exhaust air from the galley area and from the local waste heat-generating component for cooling the refrigerant of the refrigeration unit promotes past the condenser. In the context of this description, the term "condenser" also includes a gas cooler. Compared to a separate exhaust air duct for the built-in component, there is no exhaust air flow, which originates solely from the built-in component. In contrast, the exhaust air flow at the condenser of the refrigeration unit does not change "Thus, although the waste heat from the built-in component is dissipated, the overall outgoing air flow is reduced. This has the advantage that no increased cooling capacity is required for fresh air treatment by the refrigeration unit. Since, for example, an extractor hood ("steamer") ) is only operated sequentially, there are no increased demands on the capacitor.
Bevorzugt wird die Abluft aus dem Galley-Bereich und die Ab luft von der wenigstens einen Einbaukomponente auf einer Ein gangsseite des Kondensator-Lüfters zusammengeführt und damit fördert der Lüfter einen Luftstrom an dem Kondensator vorbei, der aus der Abluft aus dem Galley-Bereich insgesamt und der lokalen Abluft, die von der Einbaukomponente stammt, zusam mengesetzt ist. The exhaust air from the galley area and the exhaust air from the at least one built-in component are preferably brought together on an input side of the condenser fan and the fan thus promotes an air flow past the condenser, which consists of the exhaust air from the galley area as a whole and of the local exhaust air originating from the built-in component.
Der Luftkanal kann vom Ort der wenigstens einen Einbaukompo nente aus in einen Zwischenraum zwischen einer Innenverklei dung und einen Rohbau des Fahrzeugs, daran anschließend längs des Fahrzeugs von da aus zur Eingangsseite des Kondensators des Kälteaggregats geführt sein. In dieser Weise wird eine günstige Führung für den Luftkanal zum Fördern der Abluft der Einbaukomponente realisiert. The air duct can be routed from the location of the at least one installation component into a gap between an interior lining and a body shell of the vehicle, then along the vehicle from there to the input side of the condenser of the refrigeration unit. In this way, a favorable routing for the air duct for conveying the exhaust air from the built-in component is realized.
Bevorzugt kann das Fahrzeug als Restaurantwagen eines Zuges ausgebildet sein. The vehicle can preferably be designed as a restaurant car of a train.
Die wenigstens eine Einbaukomponente kann insbesondere von einem Dunstabzug gebildet sein, der an den Luftkanal ange schlossen ist. Der Dunstabzug ist innerhalb eines Galley- Bereichs diejenige Einbaukomponente, die erfahrungsgemäß lo kal die größte Abwärme erzeugt. Daher kommen die Vorteile der Erfindung bei dieser Einbaukomponente besonders zum Tragen. The at least one built-in component can in particular be formed by a fume hood that is connected to the air duct. The fume hood is inside a galley area, that built-in component which, based on experience, generates the greatest waste heat locally. Therefore, the advantages of the invention are particularly evident in this built-in component.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnungen noch näher erläutert. Es zei gen: An embodiment of the invention is explained in more detail below with reference to the drawings. Show it:
Figur 1 eine perspektivische Ansicht eines Teils eines Res taurantwagens und Figure 1 is a perspective view of part of a restaurant and taurantwagens
Figur 2 eine schematische Blockdiagrammdarstellung eines Kälteaggregats zum Einbau in den Restaurantwagen von Figur 1. Figure 2 is a schematic block diagram representation of a refrigeration unit for installation in the restaurant car of Figure 1.
Wie Figur 1 zu entnehmen ist, sind in dem dargestellten Teil eines Restaurantwagens 1, der beispielsweise einer der Wagen eines Hochgeschwindigkeitszuges ist, ein Kälteaggregat 2, ein Galley-Bereich 3 für Fahrgäste und eine Dunstabzugshaube („Steamer") 4 angeordnet. Von der Dunstabzugshaube 4 lokal aufgenommene, erwärmte Fortluft wird über einen Luftkanal 5 dem Kälteaggregat 2 zugeleitet. As can be seen from Figure 1, a refrigeration unit 2, a galley area 3 for passengers and an extractor hood (“steamer”) 4 are arranged in the illustrated part of a restaurant car 1, which is, for example, one of the cars of a high-speed train. From the extractor hood 4 locally absorbed, heated exhaust air is fed to the refrigeration unit 2 via an air duct 5 .
Wie in Figur 1 ersichtlich, ist die Dunstabzugshaube 4 ent fernt von dem Kälteaggregat 2 angeordnet. Das Kälteaggregat 2 befindet sich benachbart einer Stirnwand 6 des Restaurantwa gens 1. Demgegenüber ist die Dunstabzugshaube 4, bezogen auf die Längserstreckung des Restaurantwagens 1, etwa mittig an geordnet. Der Luftkanal 5 ist vom Ort der Dunstabzugshaube 4 aus in einen Zwischenraum zwischen einer Innenverkleidung und einem Rohbau des Restaurantwagens 1, daran anschließend längs des Restaurantwagens 1 und von da aus zum Kälteaggregat 2 ge führt. As can be seen in FIG. 1, the extractor hood 4 is arranged remotely from the refrigeration unit 2. The refrigeration unit 2 is located adjacent to an end wall 6 of the Restaurantwa gens 1. In contrast, the extractor hood 4, based on the longitudinal extension of the restaurant car 1, arranged approximately in the middle. The air duct 5 is from the location of the extractor hood 4 in a space between an inner lining and a shell of the restaurant car 1, then along the restaurant car 1 and from there to the refrigeration unit 2 ge leads.
Aus Figur 2 geht der Aufbau des Kälteaggregats 2 mehr im De tail hervor. Das Kälteaggregat 2 umfasst ein Expansionsventil 7, einen Verdampfer/Kühler 8 mit zugeordnetem Lüfter 9, einen Verdichter 10 mit einer Leistung von beispielsweise 6 kW und einen Kondensator 11 mit zugeordnetem Kondensator-Lüfter 12. FIG. 2 shows the structure of the refrigeration unit 2 in more detail. The refrigeration unit 2 includes an expansion valve 7, an evaporator / cooler 8 with an associated fan 9, a Compressor 10 with an output of 6 kW, for example, and a condenser 11 with an associated condenser fan 12.
Von der Dunstabzugshaube 4 kommende Abluft ist in Figur 2 mit einem Pfeil 13 und aus dem Galley-Bereich 3 herrührende Ab luft ist mit einem Pfeil 14 veranschaulicht. Wie in Figur 2 mittels eines weiteren Pfeiles 15 symbolisiert, werden die Abluft von der Dunstabzugshaube 4 sowie die Abluft aus dem Galley-Bereich 3 auf einer Ansaugseite des Kondensator- Lüfters 12 zusammengeführt und passieren den Kondensator 11, so dass auf dessen Ausgangsseite ein mit einem Pfeil 16 be- zeichneter Luftstrom vorliegt. Der Luftstrom 16 wird teils als Fortluft an die Umgebung des Restaurantwagens 1 abgeführt und teilweise in den Galley-Bereich 3 zurückgeleitet. Exhaust air coming from the extractor hood 4 is illustrated in FIG. As symbolized by a further arrow 15 in Figure 2, the exhaust air from the extractor hood 4 and the exhaust air from the galley area 3 are brought together on an intake side of the condenser fan 12 and pass through the condenser 11, so that on its outlet side a Air flow indicated by arrow 16 is present. The air flow 16 is discharged partly as exhaust air to the surroundings of the restaurant car 1 and partly fed back into the galley area 3 .
Der Kondensator-Lüfter 12 wird beispielsweise in der Weise betrieben, dass er einen Luftstrom von 400 m3/Stunde an dem Kondensator 11 vorbeiführt. Demgegenüber müsste eine geson derte Fortluftabsaugung allein für die Dunstabzugshaube 4 ty pischer Weise mit einem weiteren Lüfter bewerkstelligt wer den, der sequenziell einen Fortluftstrom von beispielsweise 200 m3/Stunde erzeugt. Durch die hier vorgestellte gemeinsame Absaugung der Abluft 13 der Dunstabzugshaube 4 und der Abluft 14 des Galley-Bereichs 3 wird somit etwa 200 m3/Stunde an zu beförderndem Fortluftstrom eingespart. Dies hat wiederum die Folge, dass weniger Frischluft mit Hilfe des Kälteaggregats 2 für eine Zuluft des Galley-Bereiches 3 konditioniert werden muss, was beispielsweise Temperatur und Luftfeuchtigkeit an geht. Gleichzeitig wird sichergestellt, dass die an der Dunstabzugshaube 4 vorliegende erwärmte Abluft 13 nicht in andere Teile des Restaurantwagens 1 gelangt, sondern vielmehr über das Kälteaggregat 2 und dort jenseits des Kondensator 11 wenigstens teilweise als Fortluft abgeführt wird. The condenser fan 12 is operated, for example, in such a way that it guides an air flow of 400 m 3 /hour past the condenser 11 . In contrast, a separate exhaust air extraction system for the extractor hood 4 would typically have to be accomplished with another fan that sequentially generates an exhaust air flow of, for example, 200 m 3 /hour. The joint extraction of the exhaust air 13 from the extractor hood 4 and the exhaust air 14 from the galley area 3 that is presented here saves about 200 m 3 /hour of exhaust air flow to be conveyed. This in turn has the consequence that less fresh air has to be conditioned with the aid of the refrigeration unit 2 for supply air to the galley area 3, which concerns temperature and humidity, for example. At the same time, it is ensured that the heated exhaust air 13 present at the extractor hood 4 does not reach other parts of the restaurant car 1, but rather is at least partially discharged as exhaust air via the refrigeration unit 2 and there beyond the condenser 11.
