Abstract
Description
Die Erfindung betrifft eine in ein Kühltransport-Fahrzeug eingebaute Einrichtung zur Klimatisierung der Fahrerkabine, bei welcher die niedrige Temperatur des Kühlraumes benützt wird, um die Fahrerkabine zu klimatisieren. Erfindungsgemäss wird dabei Kaltluft aus dem Kühlraum mittels eines zusätzlichen Wärmetauschers durch Wärmeleitung transportiert und und in einem gesonderten, von der Kühlraumluft unabhängigen Kreislauf in die Fahrerkabine eingeblasen. Der zusätzliche Wärmetauscher ist vorzugsweise im Inneren des isolierten Kühlraumes an der Stirnwand, welche den Kühlraum von der Fahrerkabine abtrennt, angeordnet. Dieser Wärmetauscher weist mindestens an seiner Ober- und Unterseite vorzugsweise aus Kuststoff bestehende Gehäuse auf, die dazu dienen, einen von der Ausblasöffnung des Kühlraumverdampfers abgezweigten Luftstrom von oben in eine Strömungskammer des Wärmetauschers einzuleiten und an der Unterseite wieder in den Kühlraum zurückzuführen und ausserdem einen durch ein Gebläse aus der Fahrerkabine von unten in die parallel zur ersten Strömungskammer verlaufende zweite Strömungskammer einzublasen und oben, inzwischen abgekühlt, wieder in die Fahrerkabine einzuleiten. Dabei wird, um unangenehme Zugerscheinungen zu vermeiden, die Luft in ein unter der Decke der Fahrerkabine angeordnetes kissenähnliches flaches Hohlgebilde aus vorzugsweise textilähnlichem Material eingeblasen und derart gleichmässig verteilt. The invention relates to a device installed in a refrigerated transport vehicle Air conditioning of the driver's cabin, using the low temperature of the cold room to air-condition the driver's cabin. According to the invention, cold air from the Cold room transported by means of an additional heat exchanger through heat conduction and and in a separate circuit independent of the cold room air into the Blown in driver's cabin. The additional heat exchanger is preferably insulated inside Cooling space on the front wall, which separates the cooling space from the driver's cabin, arranged. This heat exchanger has at least on its top and bottom preferably made of plastic housing, which serve to one of the Air outlet of the cold room evaporator branched air flow from above into a Initiate flow chamber of the heat exchanger and at the bottom again in the cooling room and also by a blower from the driver's cab from below into the to blow in the second flow chamber running parallel to the first flow chamber and above, now cooled, to be reintroduced into the driver's cabin. In doing so, um to avoid unpleasant drafts, the air in under the covers of the Driver's cab arranged cushion-like flat hollow structure made of preferably textile-like Blown in material and evenly distributed.
Der Wärmetauscher selbst besteht aus gut wärmeleitendem Material, vorzugsweise Aluminium, und ist aus gleichartigen Strangprofilelementen zusammengesetzt, sodass die Breite des Wärmetauschers variiert werden kann. Die Konstruktion des Wärmetauschers kann dabei unterschiedlich sein. So können z. B. die parallel verlaufenden Strömungskammern so angeordnet sein, dass sie durch eine durchgehende Zwischenwand getrennt sind und dass in jeder Strömungskammer im gleichen Abstand quer verlaufende, dünnwandeige Zwischenwände zur Wärmeleitung angeordnet sind. Der Wärmetauscher kann aber auch so ausgebildet sein, dass die Luftströmung im Kühlraum und die Luftströmung für die Fahrerkabine nur durch dünnwandige Querwände getrennt sind, die einen geringen Abstand voneinander haben, wobei jeweils abwechselnd ein Kanal für Kühlraumluft, dann für Fahrerkabinenluft, danach wieder für Kühlraumluft und so fort, benützt wird. Die Luftzu- und -ableitung für die beiden Strömungskammern erfolgt, je nach der konstruktiven Ausbildung des Wärmetauschers durch Luftführungen, welche vorzugsweise aus Kunststoff gefertigt sind. The heat exchanger itself is made of a good heat-conducting material, preferably Aluminum, and is composed of similar extruded profile elements, so that the width of the heat exchanger can be varied. The construction of the heat exchanger can be different. So z. B. the parallel flow chambers so be arranged that they are separated by a continuous partition and that in each flow chamber at the same distance transversely running, thin-walled Partitions are arranged for heat conduction. The heat exchanger can also do so be designed so that the air flow in the refrigerator and the air flow for the driver's cabin only are separated by thin-walled transverse walls that are a short distance apart have, alternating in each case one channel for cold room air, then for driver cabin air, then used again for cold room air and so on. The air supply and discharge for the two flow chambers, depending on the design of the Heat exchanger through air ducts, which are preferably made of plastic.

Der Längsschnitt in Fig. 1 zeigt unter (1) ein auf dem Dach angeordnetes Kühlgerät, welches soweit in den Innenraum hineinragt (2), dass bei (3) gekühlte Luft in den Kühlraum geblasen und bei (4) nach Umlauf durch den Kühlraum zur abermaligen Kühlung wieder angesaugt wird. Ein Teil der bei (3) austretenden Kühlluft wird über einen Kanal (3a) abgezweigt und einem speziellen Wärmetauscher (5) von oben zugeführt. Diese Luft tritt unten bei (4b) wieder in den Kühlraum ein. Der Wärmetauscher (5) ist vorzugsweise an der isolierten Trennwand (6) zwischen Kühlraum und Fahrerkabine (10) angeordnet. Neben einer Strömungskammer (5a) für die über den Kanal (3a) abgezweigte Kühlraumluft hat der Wärmetauscher (5) noch eine zweite Strömungskammer (5b), welche luftseitig mit der Fahrerkabine (10) in Verbindung steht. Durch ein Gebläse (7) in der Fahrerkabine wird Luft durch den Kanal (8a) von unten der Strömungskammer (5b) zugeführt und oben, nach Abkühlung durch den Kanal (8b) wieder in die Fahrerkabine eingeblasen. Um unangenehme Zugerscheinungen zu vermeiden, wird die abgekühlte Luft in ein an der Decke aneordnetes kissenähnliches Hohlgebilde (9) aus Textil oder textilähnlichem Material eingeblasen und dabei gleichmässig verteilt. The longitudinal section in Fig. 1 shows under ( 1 ) a cooling device arranged on the roof, which projects into the interior ( 2 ) to such an extent that at ( 3 ) cooled air is blown into the cooling room and at ( 4 ) after circulation through the cooling room repeated cooling is sucked in again. Part of the cooling air emerging at ( 3 ) is branched off via a duct ( 3 a) and fed to a special heat exchanger ( 5 ) from above. This air enters the refrigerator compartment at ( 4 b) below. The heat exchanger ( 5 ) is preferably arranged on the insulated partition ( 6 ) between the cooling space and the driver's cabin ( 10 ). In addition to a flow chamber ( 5 a) for the cooling chamber air branched off via the channel ( 3 a), the heat exchanger ( 5 ) also has a second flow chamber ( 5 b), which is connected to the driver's cabin ( 10 ) on the air side. A blower ( 7 ) in the driver's cabin feeds air through the duct ( 8 a) from below to the flow chamber ( 5 b) and, after cooling through the duct ( 8 b), blows it back into the driver's cabin. In order to avoid unpleasant drafts, the cooled air is blown into a cushion-like hollow structure ( 9 ) made of textile or textile-like material arranged on the ceiling and is evenly distributed.
Der Wärmetauscher (5) wird in der erforderlichen Breite durch mehrere, nebeneinander angeordnete, gleiche Elemente aufgebaut. Fig. 3 zeigt ein erstes Strangpressprofil (11), das durch Aneinanderreihen mehrerer solcher Profile den erforderlichen Wärmetauscher (5) ergibt. Durch geeignete Elemente (13, 14, 15, 16, 17) können die Profile (11) miteinander verbunden werden. Die beiden Strömungskanäle (5a) und (5b) sind durch eine Zwischenwand (5c) getrennt. Die Wände (5c, 5d, 5e, 5f) sind vorzugsweise zwischen 1,5 und 2,0 Millimeter dick. Die Zwischenwände (12) sind vorzugsweise 1 mm oder weniger dick. Der Wärmetauscher von Fig. 4 zeigt als Beispiel ein zweites zusammensetzbares Strangpressprofil (13), welches 4 Winkel (14) an den Kanten aufweist. Mittels Profilen (15), vorzugsweise aus Kunststoff können mehrere Profile (13) nebeneinander befestigt werden. Bei dieser Konstruktion sind die Strömungskammern (5a) und (5b) in abwechselnd nacheinander folgende Kanäle (16) und (17) aufgesplittet. Die Aussenwände (18) sind auch hier vorzugsweise 1,5 bis 2,0 mm dick, während die Dicke der Zwischenwände (19) vorzugsweise 1,0 mm oder weniger betragen sollte. Bei dieser Konstruktion kann es vorteilhaft sein, wenn die Zwischenwände (19) nicht geradlinig, sondern beispielsweise gewellt sind, oder im Ziczack verlaufen, um die Wärmeübertragungsfläche zu erhöhen. Wie Fig. 5 zeigt, benötigt ein Wärmetauscher nach Fig. 3/4 oben eine Haube (20), vorzugsweise aus Kunststoff, welche die Strömungskanäle (5a) und (5b) trennt, einen Anschluss (20a) für den Zuluftkanal (3a) und einen Anschluss (20b) zum Durchbruch (8b). Unten benötigt der Wärmetauscher nach Fig. 3. lediglich eine Anschlusshaube (21) für den Zuluftkanal (8a). Beim Wärmetauscher nach Fig. 4 sind die Anschlusshauben oben und unten rein konstruktiv etwas aufwendiger, denn die nebeneinanderliegend aufgesplitteten Kanäle (16, 17, 16, 17, . . .) sind für alle Kanäle (16), sowie für alle Kanäle (17) als Strömungskanäle (5a) und (5b) getrennt zusammenzufassen. Dies stellt jedoch keine grosse konstruktive Schwierigkeit dar. Die erfindungsgemässe Einrichtung erspart den Einbau eines gesonderten Klimagerätes für die Fahrerkabine. Zur Steuerung dienen geeignete Regelgeräte. The heat exchanger ( 5 ) is constructed in the required width by several identical elements arranged side by side. Fig. 3 shows a first extruded profile ( 11 ), which results in the necessary heat exchanger ( 5 ) by stringing together several such profiles. The profiles ( 11 ) can be connected to one another by suitable elements ( 13 , 14 , 15 , 16 , 17 ). The two flow channels ( 5 a) and ( 5 b) are separated by an intermediate wall ( 5 c). The walls ( 5 c, 5 d, 5 e, 5 f) are preferably between 1.5 and 2.0 millimeters thick. The partitions ( 12 ) are preferably 1 mm or less thick. The heat exchanger of FIG. 4 shows, as an example, a second extruded profile ( 13 ) which can be assembled and which has 4 angles ( 14 ) at the edges. Using profiles ( 15 ), preferably made of plastic, several profiles ( 13 ) can be attached next to one another. In this construction, the flow chambers ( 5 a) and ( 5 b) are split into alternating channels ( 16 ) and ( 17 ). The outer walls ( 18 ) are also preferably 1.5 to 2.0 mm thick here, while the thickness of the intermediate walls ( 19 ) should preferably be 1.0 mm or less. With this construction, it can be advantageous if the partitions ( 19 ) are not straight, but are, for example, corrugated, or zigzag to increase the heat transfer area. As shown in FIG. 5, a heat exchanger according to FIGS. 3/4 above requires a hood ( 20 ), preferably made of plastic, which separates the flow channels ( 5 a) and ( 5 b), a connection ( 20 a) for the supply air channel ( 3 a) and a connection ( 20 b) to the breakthrough ( 8 b). The bottom of the heat exchanger according to Fig. 3 only requires a connection hood ( 21 ) for the supply air duct ( 8 a). In the heat exchanger according to Fig. 4, the connector hoods are above and below purely constructively somewhat more complicated, because the juxtaposed divide in (... 16, 17, 16, 17,) channels are for all channels (16), as well as for all channels (17) summarize as flow channels ( 5 a) and ( 5 b) separately. However, this is not a major design difficulty. The device according to the invention saves the installation of a separate air conditioner for the driver's cabin. Suitable control devices are used for control.
