Dabei ist insbesondere vorgesehen, dass der Wärmeträger einen vorzugsweise flachquaderförmigen Pufferspeicher durchströmt, der mit einem ersten Abschnitt im Kondensatorteil oder unterhalb von diesem und mit einem zweiten Abschnitt im Verdampferteil und unterhalb von diesem angeordnet ist.In this case, provision is made in particular for the heat carrier to flow through a preferably flat-quadrilateral buffer store which is arranged with a first section in the condenser part or below it and with a second section in the evaporator part and below it.

Erfindungsgemäß wird in dem Kondensatorteil eine Brennstoffheizung integriert, die Heizleistungen ermöglicht, die die von elektrischen Heizungen bei üblichen Anschlussleistungen um ein Mehrfaches übersteigen kann. Leistungen von z.B. 30 kW sind ohne Weiteres möglich, ohne dass das Kondensatorteil volumenmäßig vergrößert wird. Durch die Trennung der Brennstoffheizung von dem ersten Wärmetauscher und dessen Anordnung im Verdampferteil kann die über den Ventilator angesaugte Luft sowohl den Verdampfer als auch den Wärmetauscher durchströmen, um so im erforderlichen Umfang einen Raum wie insbesondere ein Zelt über einen großen Temperaturbereich klimatisieren zu können, insbesondere über einen Bereich zwischen - 32°C und +60°C Umgebungstemperatur.According to the invention, a fuel heater is integrated in the condenser part, which enables heating capacities which can exceed that of electric heaters by a common factor at conventional connection powers. Services of e.g. 30 kW are readily possible, without the capacitor part is increased in volume. By separating the fuel heater from the first heat exchanger and its arrangement in the evaporator part, the air sucked in via the fan can flow through both the evaporator and the heat exchanger so as to be able to condition a space, in particular a tent, over a wide temperature range to the required extent, in particular over a range between - 32 ° C and + 60 ° C ambient temperature.

Um ein Takten der Brennstoffheizung zu verhindern, ist ein Pufferspeicher vorgesehen, der von dem Wärmeüberträger durchströmt wird - und zwar im Rücklauf von dem ersten Wärmetauscher. Ungeachtet dessen wird die Kompaktheit des Gerätes gewahrt, da der Pufferspeicher abschnittsweise im Bodenbereich sowohl des Kondensatorteils als auch des Verdampferteils angeordnet ist, und zwar vorzugsweise unterhalb des das Kondensatorteil und das Verdampferteil umgebenden Gehäuses. Durch die abschnittsweise Anordnung sowohl im Bereich des Kondensatorteils als auch des Verdampferteils ist eine einfache Verrohrung möglich, die die gewünschte Kompaktheit sicherstellt. Insbesondere sollte der Pufferspeicher ein Volumen von 30 dm3 aufweisen.In order to prevent a clocking of the fuel heater, a buffer memory is provided, which is flowed through by the heat exchanger - in the return from the first heat exchanger. Regardless, the compactness of the device is maintained, since the buffer memory is arranged in sections in the bottom region of both the condenser part and the evaporator part, preferably below the condenser part and the evaporator part surrounding housing. The sectional arrangement both in the region of the condenser part and the evaporator part, a simple piping is possible, which ensures the desired compactness. In particular, the buffer should have a volume of 30 dm3.

Der zweite Wärmetauscher, über den die Wärme der Brennstoffheizung aus dem Wärmeträger wie Wasser-Glykol-Gemisch übertragen wird, wird über eine erste Leitung mit der Einlassöffnung des ersten Wärmetauschers verbunden, wobei ein erster Leitungsabschnitt entlang des ersten Abschnitts und ein zweiter Leitungsabschnitt entlang des zweiten Abschnitts des Pufferspeichers verläuft, wobei von der Auslassöffnung des ersten Wärmetauschers eine zweite Leitung ausgeht, die mit im zweiten Abschnitt des Pufferspeichers angeordneten Einlassöffnung verbunden ist, dessen über eine dritte Leitung mit dem zweiten Wärmetauscher verbundene Auslassöffnung von dem ersten Abschnitt des Pufferspeichers ausgeht.The second heat exchanger, via which the heat of the fuel heater is transferred from the heat carrier such as water-glycol mixture is connected via a first line to the inlet opening of the first heat exchanger, wherein a first line section along the first section and a second line section along the second Section of the buffer memory runs, wherein from the outlet opening of the first heat exchanger, a second line is connected, which is connected to the second portion of the buffer inlet opening arranged, whose connected via a third line to the second heat exchanger outlet opening from the first portion of the buffer memory.

Durch die diesbezügliche Anordnung und Verbindungsart wird die gewünschte Kompaktheit sichergestellt.The arrangement and type of connection in this way ensures the desired compactness.

Des Weiteren zeichnet sich die Erfindung dadurch aus, dass das Klimagerät ein Gerätegehäuse mit einer Quaderform aufweist, dass sich entlang zwei aneinandergrenzender Seitenflächen des Gerätegehäuses jeweils ein eine Quaderform aufweisender Abschnitt des Kondensators erstreckt, dass benachbart zu einem der Abschnitte der Verdichter und benachbart zu dem anderen Abschnitt ein Ausdehnungsbehälter der Brennstoffheizung angeordnet ist und dass das Gehäuse der Brennstoffheizung zwischen dem Verdichter und dem Ausdehnungsbehälter und mit seiner Längsachse geneigt zu von den Abschnitten des Kondensators aufgespannten Ebenen angeordnet ist. Durch diese Anordnung kann eine optimale Raumausnutzung im Kondensatorteil erfolgen, ohne dass gegenüber Klimageräten, die eine entsprechende Brennstoffheizung nicht aufweisen, eine volumenmäßige Vergrößerung erfolgen muss.Furthermore, the invention is characterized in that the air conditioner comprises a device housing having a cuboid shape that extends along two adjacent side surfaces of the device housing each having a cuboid portion of the capacitor that adjacent to one of the sections of the compressor and adjacent to the other Section is arranged an expansion tank of the fuel heater and that the housing of the fuel heater between the compressor and the expansion tank and is arranged with its longitudinal axis inclined to the sections of the capacitor spanned planes. As a result of this arrangement, optimal space utilization in the condenser part can be achieved without an increase in volume being required compared to air conditioning units which do not have a corresponding fuel heater.

Das Gerätegehäuse sollte schwingend auf einer Transportplatte gelagert und mit dieser verbunden sein, wobei die Transportpalette bevorzugterweise Stapeltaschen aufweist.The device housing should be mounted swinging on a transport plate and connected thereto, wherein the transport pallet preferably has stacking pockets.

Das Gerätegehäuse selbst weist bevorzugterweise einen Rahmen mit kopfseitigen Stegen auf, die Ausschnitte zur Aufnahme von Stapeltaschen einer weiteren Transportpalette aufweisen, wobei die Ausschnitte von Normalen der Stapeltaschen der Transportpaletten geschnitten werden. Somit können mehrere Klimageräte gestapelt werden. Folglich ist ein raumsparender Transport möglich.The device housing itself preferably has a frame with head-side webs, which have cutouts for receiving stacking pockets of a further transport pallet, wherein the cut-outs are cut by normals of the stacking pockets of the transport pallets. Thus, several air conditioners can be stacked. Consequently, a space-saving transport is possible.

Das Ausdehnungsgefäß sollte zwischen einem von dem zweiten Wärmetauscher ausgehenden und in den ersten Leitungsabschnitt übergehenden Abschnitt der den Wärmeträger führenden Leitung und/oder eine den Wärmeträger fördernde Pumpe sollte in einem von dem Pufferbehälter zu dem zweiten Wärmetauscher führenden Leitungsabschnitt angeordnet sein.The expansion vessel should be arranged between a line leading from the second heat exchanger and into the first line section of the line leading to the heat carrier and / or a pump conveying the heat carrier should be arranged in a line section leading from the buffer tank to the second heat exchanger.

Durch all diese Maßnahmen wird die Kompaktheit sichergestellt.
Der die zu klimatisierende Luft ansaugende Ventilator sollte ein Radialventilator sein und zwischen der Trennwand und dem ersten Wärmetauscher angeordnet sein.All these measures ensure compactness.
The fan sucking the air to be conditioned should be a radial fan and should be located between the partition wall and the first heat exchanger.

Die das Verdampferteil begrenzende Stirnwandung des Gerätegehäuses weist zumindest eine Öffnung oder einen Anschluss für anzusaugende Luft auf. Entlang einer gegenüberliegenden, das Kondensatorteil stirnseitig begrenzender Wandung geht eine mit der Brennstoffheizung verbundene Abgasleitung aus, die zum Transport abnehmbar ist.The evaporator part bounding end wall of the device housing has at least one opening or a connection for air to be sucked.

Das Klimagerät bietet einen universellen Einsatz und kann insbesondere beim Katastrophenschutz zum Einsatz gelangen. Das Klimagerät kann sowohl als Umluftgerät mit definiertem Frischluftanteil, als reines Außenluftgerät (100 % Frischluft) oder als reines Umluftgerät (100 %) betrieben werden. Die Anbindung an einen zu klimatisierenden Raum wie ein Zelt erfolgt über ein Schlauchsystem. Das Klimagerät ist technisch derart ausgelegt, dass bei einer Umgebungstemperatur zwischen -32 °C und +60 °C ein Einsatz möglich ist. Das typischerweise Abmessungen von 1.800 mm x 885 mm x 980 mm aufweisende Klimagerät besteht aus einem Kondensatorteil und einem Verdampferteil und ist auf einer Transportpalette einschließlich Staplertasche schwingend gelagert. Eine Stapelbarkeit ist gegeben. Kondensator- und Verdampferteil sind durch eine isolierende Trennwand thermisch voneinander getrennt und nur durch die Kälte- und Wärmeträgerkreisverrohrung miteinander verbunden.In summary, the air conditioner according to the invention is described as follows, wherein the highlighted features do not necessarily have to be used in combination. The air conditioner offers a universal application and can be used in particular for civil protection. The air conditioner can be operated both as recirculation unit with defined fresh air proportion, as pure outdoor air unit (100% fresh air) or as pure recirculation unit (100%). The connection to a room to be air-conditioned, such as a tent, takes place via a hose system. The air conditioner is technically like that designed to operate at ambient temperatures between -32 ° C and + 60 ° C. The air conditioner, which typically has dimensions of 1,800 mm × 885 mm × 980 mm, consists of a condenser part and an evaporator part and is swing-mounted on a transport pallet including a stacker pocket. A stackability is given. Capacitor and evaporator part are thermally separated from each other by an insulating partition and connected only by the refrigeration and Wärmeträgerkreisverrohrung.

Im Kondensatorteil befindet sich sowohl die Kältetechnik (wie Kondensatorlüfter, Wärmetauscher, Sammler, Trockner, Kälteverrohrung, Ventile und Sicherheitsorgane) als auch die notwendige Heiztechnik (Brennstoffheizung, Ausdehnungsgefäß, Heizpumpe, Elektronik, Verrohrung und Abgasleitung). Im Verdampferteil befinden sich das E-Teil, der Umlüfter (Ventilator), der Verdampfer (zur Kühlung) sowie der Wärmeträgertauscher (Brennstoffheizung), Regelorgane und Rohrleitungen für den Kühl- und Heizkreislauf. Unterhalb des Gehäuses des Klimagerätes ist ein Pufferspeicher angebracht, der ein Takten der Brennstoffheizung verhindert. Der Pufferspeicher, der eine Quadergeometrie aufweist, sollte ein Volumen von ca. 30 dm3 aufweisen.The condenser section contains both the refrigeration technology (such as condenser fans, heat exchangers, collectors, dryers, refrigeration piping, valves and safety devices) and the necessary heating technology (fuel heater, expansion vessel, heating pump, electronics, piping and exhaust pipe). In the evaporator section are the E-part, the fan (fan), the evaporator (for cooling) and the heat transfer (fuel heating), control elements and piping for the cooling and heating circuit. Below the housing of the air conditioner, a buffer memory is mounted, which prevents a clocking of the fuel heater. The buffer memory, which has a cuboid geometry, should have a volume of approximately 30 dm3.

Das Klimagerät kann über ein steckbares Bedienteil mit Thermostat angesteuert werden. Über das Bedienteil können alle Funktionen der Anlage vorgegeben werden.

All functions of the system can be specified via the control panel. Due to the preselectable setpoint temperature, the air conditioner will automatically heat or cool accordingly. Error messages in the event of a fault can be signaled to the keypad as a group fault.

Die entstehenden Abgase beim Brennstoffheizen werden über ein an der das Kondensatorteil stirnseitig begrenzenden Außenwand des Gehäuses befestigtes Abgasrohr an die Umgebung abgegeben. Das Abgasrohr ist abnehmbar. Die Abgase können nicht in den luftführenden Teil des Verdampfers gelangen, so dass die bei der Verbrennung des Kraftstoffes entstehende Wärme der Brennstoffheizung über einen Wärmetauscher auf ein Wärmeträgermedium übertragen wird und dieses wiederum über einen Wärmetauscher auf der Verdampferseite an die Zuluft abgegeben wird. Es erfolgt ein indirektes Heizen.The resulting exhaust gases during fuel heating are discharged via an attached to the condenser part end face bounding outer wall of the housing exhaust pipe to the environment. The exhaust pipe is removable. The exhaust gases can not get into the air-conducting part of the evaporator, so that the heat of the fuel heating resulting from the combustion of the fuel is transferred via a heat exchanger to a heat transfer medium and this in turn is discharged via a heat exchanger on the evaporator side to the supply air. There is an indirect heating.

Die Spannungsversorgung der Anlage erfolgt über ein Netzkabel. Dabei kann ein Betrieb über ein herkömmliches Stromnetz oder einen Generator erfolgen.The system is supplied with power via a mains cable. In this case, operation via a conventional power grid or a generator can take place.

Zum Versorgen der Brennstoffheizung wird ein Tank benutzt, der außerhalb des Gerätes aufgestellt wird und mit der Heizung über einen Schnellverschluss verbunden ist. Als Brennstoffe kommen Diesel und Heizöl in Frage. Ein Anschluss z.B. eines 20 1 Kanisters oder eines 200 1 Fasses ist möglich.To supply the fuel heater, a tank is used, which is placed outside the unit and connected to the heater via a quick release. The fuels used are diesel and heating oil. A connection e.g. a 20 1 canister or a 200 1 barrel is possible.

This gives the possibility to stack at least two corresponding air conditioners 10, wherein the upper air conditioner must take a clear position due to the notches 26, 28, 30, 32 to the lower air conditioner.

Das erfindungsgemäße Klimagerät besteht aus einem Kondensatorteil 34 und einem Verdampferteil 36, die durch eine thermisch isolierende Trennwand 38 getrennt sind.The air conditioner according to the invention consists of a condenser part 34 and an evaporator part 36, which are separated by a thermally insulating partition wall 38.

Als wesentliche Bestandteile befinden sich in dem Kondensatorteil 34 zwei jeweils von einem eine Quaderform aufweisenden Gehäuse umgebenen Kondensatorabschnitte 40, 42, ein Kondensatorventilator 44, über den über eine in der Seitenwandung 46 vorhandene Öffnung 48 Luft angesaugt wird, ein Verdichter 50, eine Brennstoffheizung 52, ein in dem Wärmeträgerkreislauf der Brennstoffheizung 52 angeordneter Ausdehnungsbehälter 54, ein Saugdruckregler 56 sowie ein Elektrikteil (E-Teil) 58 für die Brennstoffheizung 52.As essential components are located in the condenser part 34 two each surrounded by a cuboid housing housing condenser sections 40, 42, a condenser fan 44 through which an existing opening 48 in the side wall 48 air is drawn, a compressor 50, a fuel heater 52, a arranged in the heat transfer circuit of the fuel heater 52 expansion tank 54, a suction pressure regulator 56 and an electrical part (E-part) 58 for the fuel heater 52nd

Die Brennstoffheizung 52, die einen Aufbau wie eine Standheizung aufweisen kann und ein zylindrisches Gehäuse 60 aufweist, ist über einen Schnellverschluss 62 mit einem außerhalb des Klimageräts 10 aufstellbaren nicht dargestellten Tank oder Kanister zur Versorgung mit Brennstoff verbunden.The fuel heater 52, which may have a structure such as a heater and has a cylindrical housing 60 is connected via a quick release 62 with an outside of the air conditioner 10 can be set up, not shown tank or canisters for supplying fuel.

Von der Brennstoffheizung 52 geht eine Leitung 64 aus, die in ein Abgasrohr 68 mündet, das entlang der das Kondensatorteil 34 begrenzenden Stirnwandung 67 verläuft und von der die Abgasleitung 64 abnehmbar ist. Dies erfolgt dann, wenn das Klimagerät 10 transportiert wird.From the fuel heater 52 is a line 64, which opens into an exhaust pipe 68 which extends along the condenser 34 bounding end wall 67 and from which the exhaust pipe 64 is removable. This takes place when the air conditioner 10 is transported.

Zwischen der thermisch isolierten Trennwand 38 und dem ersten Wärmetauscher 72 ist ein Radialventilator 74 angeordnet, über den in der Stirnseite 76 des Gehäuses 12 angesaugte Luft einem zu klimatisierenden Raum über eine Luftaustrittsöffnung zugeführt wird. Die Luftaustrittsöffnung kann über einen Schlauch mit dem Raum verbunden sein.In the evaporator section 36, an evaporator 70 and this downstream of a first heat exchanger 72 are arranged, which is flowed through by the fuel heater 52, by a heat transfer medium flowing through a second heat exchanger, not shown. Between the thermally insulated partition wall 38 and the first heat exchanger 72, a centrifugal fan 74 is arranged, via which air sucked in the end face 76 of the housing 12 is supplied to a space to be conditioned via an air outlet opening. The air outlet opening can be connected via a hose to the room.

Über die Lufteintrittsöffnung kann - je nach Betrieb des Klimagerätes 10 - Außenluft, Abluft oder eine Mischung von Abluft und Außenluft angesaugt werden. Zwischen dem Verdampfer 70 und der Stirnwandung 76 ist im Ausführungsbeispiel ein zweistufiges Filter 78 angeordnet.Depending on the operation of the air conditioner 10, outside air, exhaust air or a mixture of exhaust air and outside air can be sucked in via the air inlet opening. Between the evaporator 70 and the end wall 76, a two-stage filter 78 is arranged in the embodiment.

Unterhalb des Gehäuses 12 und durch die Transportpalette 14 bzw. Abschnitte dieser geschützt ist ein Pufferbehälter 80 angeordnet, der sich abschnittsweise sowohl unterhalb des Kondensatorteils 34 als auch unterhalb des Verdampferteils 36 erstreckt.Below the housing 12 and protected by the transport pallet 14 or sections thereof, a buffer container 80 is arranged, which extends in sections both below the condenser part 34 and below the evaporator part 36.

Der Pufferbehälter 80 weist eine Quaderform auf und ist in den Kreislauf des Wärmeträgers wie Glykol-Wasser-Mischung der Brennstoffheizung 52 integriert, um ein Takten der Brennstoffheizung zu vermeiden. Der Pufferbehälter 10 verfügt über einen Anschluss 81, über den der Wärmeträger abgelassen werden kann.The buffer container 80 has a parallelepiped shape and is integrated in the circulation of the heat carrier such as glycol-water mixture of the fuel heater 52 in order to avoid a timing of the fuel heater. The buffer container 10 has a connection 81, via which the heat carrier can be discharged.

Wie sich aus der Fig. 6 ergibt, erstreckt sich die Brennstoffheizung 52, das heißt deren Gehäuse 60, von der Trennwand 38 in Richtung des Kondensatorgehäuses 40, das entlang der Seitenwandung des Gehäuses 12 verläuft, die in der Fig. 6 an dem oberen Rand der Zeichnung verläuft.

The housing 60 further extends between the compressor 50 and the expansion tank 54.

Durch die Positionierung des Gehäuses 60 der Brennstoffheizung 52 erfolgt eine optimale Ausnutzung des Innenraums des Kondensatorteils 34, so dass sich eine kompakte Einheit ergibt.By positioning the housing 60 of the fuel heater 52, an optimal utilization of the interior of the condenser part 34 takes place, resulting in a compact unit.

Von der Brennstoffheizung 52 getrennt ist der erste Wärmetauscher 72 parallel zu dem Verdampfer 70 angeordnet. Zum Durchströmen des ersten Wärmetauschers 72 durch den von der Brennstoffheizung 52 erwärmten Wärmeträger geht von dem Wärmetauscher der Brennstoffheizung 52, der auch zweiter Wärmetauscher genannt wird, eine Leitung aus, die unterhalb des Gehäuses 12 verläuft und im Ausführungsbeispiel an dem Pufferbehälter 80 entlang geführt wird, und zwar mit einem ersten Leitungsabschnitt 82 entlang des Abschnitts 84 des Pufferbehälters 80, der unterhalb des Kondensatorteils 34 angeordnet ist und mit einem zweiten Abschnitt 86 entlang des zweiten Abschnitts 88 des Pufferbehälters 80, der unterhalb des Verdampferteils 36 verläuft.
