Die Erfindung betrifft eine Klimaanlage für ein Kraft fahrzeug, insbesondere ein Elektrofahrzeug, mit einem Kältemittelkreislauf, der einen luftdurchströmten Ver dampfer und einen luftdurchströmten Kondensator aufweist, wobei der Abluftstrom von Verdampfer und/oder Kondensator in den Fahrzeug-Innenraum oder in die Umgebung gelangen kann.The invention relates to an air conditioning system for a power vehicle, in particular an electric vehicle, with a Refrigerant circuit that a Ver steamer and has an air-flowing condenser, the exhaust air flow from the evaporator and / or condenser get into the vehicle interior or into the environment can.
Eine derartige Klimaanlage bildet zumindest internen Stand der Technik. Diesen Stand der Technik im Hinblick auf Funktionalität und Bauaufwand zu verbessern, ist Auf gabe der vorliegenden Erfindung.Such air conditioning forms at least internal State of the art. This state of the art in view to improve on functionality and construction work is up the present invention.
Zur Lösung dieser Aufgabe ist vorgesehen, daß der Ver dampfer und der Kondensator in zumindest bereichsweise im wesentlichen nebeneinander verlaufenden Luftkanälen ange ordnet sind, denen ein gemeinsames Luftstrom-Förderge bläse vorgeschaltet ist. Vorteilhafte Aus- und Weiterbil dungen der Erfindung beschreiben die Unteransprüche.To solve this problem it is provided that the Ver steamer and the condenser in at least some areas essential side-by-side air channels are assigned to whom a common air flow conveyor blower is connected upstream. Advantageous training and further education The invention describes the subclaims.
Erfindungsgemäß genügt ein einziges Gebläse, um die Luft ströme durch den Verdampfer sowie den Kondensator des Kältemittelskreislaufes zu fördern. Die zugeordneten Luftkanäle gehen dabei von diesem gemeinsamen Gebläse aus und verlaufen zumindest anfangs nebeneinander, um gün stige und gleichmäßige Einströmverhältnisse zu erzielen. Vorteilhafterweise ist mit den erfindungsgemäßen Merkma len nicht nur lediglich ein einziges Gebläse erforder lich, sondern kann darüber hinaus die Zahl umschaltbarer Luftleitelemente, so beispielsweise Klappen, gering ge halten werden. Vorgesehen sein können derartige umschalt bare Luftleitelemente um den Abluftstrom des Verdampfers oder des Kondensators wahlweise in den Fahrzeug-Innenraum oder in die Umgebung zu leiten. Gelangt der Abluftstrom des in den Kältemittelkreislauf eingebundenen Verdampfers in den Fahrzeug-Innenraum, so wird dieser gekühlt. Eine Beheizung des Fahrzeug-Innenraumes hingegen ist möglich, wenn der Abluftstrom des Kondensators in den Innenraum geführt wird, während der Abluftstrom des Verdampfers dann in die Umgebung abgeleitet wird.According to the invention, a single blower is sufficient to blow the air flows through the evaporator and the condenser of the To promote the refrigerant circuit. The assigned Air ducts emanate from this common fan and run at least initially next to each other to to achieve steady and even inflow conditions. It is advantageous with the inventive feature len not only a single blower required Lich, the number can also be switched Air control elements, such as flaps, low ge will hold. Such switching can be provided bare air guide elements around the exhaust air flow of the evaporator or the capacitor optionally in the vehicle interior or to lead into the environment. The exhaust air flow arrives of the evaporator integrated in the refrigerant circuit inside the vehicle, it is cooled. A Heating of the vehicle interior is possible, however when the exhaust air flow of the condenser into the interior is guided, while the exhaust air flow from the evaporator then derived into the environment.
Weiter erhöht werden kann die Heizleistung der Klimaan lage durch einen weiteren Wärmetauscher, der in den Kühl mittelkreislauf der Fahrzeug-Antriebseinheit eingebunden sein kann. Bei der Fahrzeug-Antriebseinheit kann es sich um eine Brennkraftmaschine handeln; im Falle eines Elek trofahrzeuges soll unter den Begriff der Antriebseinheit neben dem Elektromotor auch eine Batterie und/oder eine elektrische Steuereinheit, die bekanntlich ebenfalls Ver lustwärme erzeugt, fallen. Selbstverständlich empfiehlt es sich, diesen Kühlmittelkreislauf-Wärmetauscher, der an einen Luftstrom Wärme abgibt, im Kondensator-Luftkanal der Klimaanlage anzuordnen. Noch weiter gesteigert werden kann die Heizleistung der Klimaanlage durch ein Heizele ment, das den Kühlmittelkreislauf erwärmt. Vorteilhafter weise erhöht ein derartiges, in einfachster Weise bei spielsweise tauchsiederähnlich ausgebildetes Heizelement den Luftströmungswiderstand der Klimaanlage nicht. The heating capacity of the Klimaan can be further increased lay through another heat exchanger, which in the cooling middle circuit of the vehicle drive unit integrated can be. The vehicle drive unit can act as an internal combustion engine; in the case of an elec trofahreses is intended under the term drive unit in addition to the electric motor also a battery and / or one electrical control unit, which is also known Ver generates heat, fall. Of course recommends it, this coolant circuit heat exchanger that is on an air stream emits heat in the condenser air duct to arrange the air conditioner. Be further increased the heating capacity of the air conditioning system by a heater ment that heats the coolant circuit. More advantageous wise increases such, in the simplest way for example, a heating element designed like an immersion heater the airflow resistance of the air conditioning system.
Besteht zwischen dem Verdampfer-Luftkanal sowie dem Kon densator-Luftkanal stromab des Verdampfers sowie stromauf eines im Kondensator-Luftkanal vorgesehenen Wärmetau schers eine Luftübertritts-Möglichkeit, so kann eine er findungsgemäße Klimaanlage im sog. reheat-Betrieb arbei ten. Dabei wird ein zu klimatisierender Luftstrom zunächst abgekühlt und anschließend erwärmt, womit eine Trocknung des Luftstromes einhergeht. Weiter gesteigert werden kann der Wirkungsgrad einer erfindungsgemäßen Kli maanlage im sog. Umluftbetrieb. Hierzu mündet stromauf des Fördergebläses neben einem Frischluft-Ansaugkanal um schaltbar oder auch nur zuschaltbar ein mit dem Fahrzeug-In nenraum verbundener Umluft-Ansaugkanal.Exists between the evaporator air duct and the con condenser air duct downstream of the evaporator and upstream a heat thaw provided in the condenser air duct schers an air transfer option, so he can Air conditioning system according to the so-called reheat mode An air flow to be air-conditioned first cooled and then warmed up, with which one Drying of the air flow goes hand in hand. Increased further can be the efficiency of a Kli invention unit in so-called recirculation mode. This opens upstream of the conveyor fan next to a fresh air intake duct switchable or only switchable with the vehicle-in Air intake duct connected to the interior.
Insbesondere im Falle eines Elektrofahrzeuges bietet es sich an, den Kompressions-Kältemittelkreislauf elektromo torisch zu betreiben. Die Kälteleistung - in diesem Fall gelangt die Verdampferabluft in den Fahrzeug-Innenraum - bzw. die Wärmeleistung - hier gelangt die Kondensatorab luft in den Innenraum - des Kältemittelkreislaufes kann dann einfach durch Variation der Drehzahl des Elektromo tors geregelt werden. In diesem Zusammenhang soll darauf hingewiesen werden, daß daneben selbstverständlich auch das ebenfalls vorzugsweise elektromotorisch angetriebene Fördergebläse sowie die ebenfalls vorzugsweise elektrisch betätigten Luftstrom-Umschaltklappen den jeweiligen Er fordernissen entsprechend insbesondere von einer elektro nischen Steuereinheit angesteuert werden können. Den Vorgabewerten eines Fahrzeuginsassen oder niedergelegten Behaglichkeitswerten entsprechend kann diese Steuerein heit darüber hinaus neben der oben erwähnten elektrischen Beheizung eines Kühlmittelkreislaufes auch eine in diesem Kreislauf vorgesehene Förderpumpe ansteuern.In the case of an electric vehicle in particular, it offers itself, the compression refrigerant circuit is electromo to operate torically. The cooling capacity - in this case the evaporator exhaust air gets into the vehicle interior - or the heat output - this is where the condenser comes off air into the interior - the refrigerant circuit can then simply by varying the speed of the electromo tors are regulated. In this context, it is said to be pointed out that of course also that is also preferably driven by an electric motor Conveyor blower and also preferably electrically operated airflow switching flaps the respective Er according to requirements in particular of an electric African control unit can be controlled. The Default values of a vehicle occupant or deposited This tax can be according to comfort values unit in addition to the above-mentioned electrical Heating a coolant circuit also one in this Activate the feed pump provided for the circuit.
Drei Prinzipskizzen (Fig. 1, Fig. 2, Fig. 3) zeigen be vorzugte Ausführungsbeispiele der Erfindung. Three schematic diagrams ( Fig. 1, Fig. 2, Fig. 3) show preferred embodiments of the invention.
Mit der Bezugsziffer 10 ist ein Kältemittelkreislauf be zeichnet, der neben einem Verdampfer 11 sowie einem Kon densator 12 einen von einem Elektromotor 13 angetriebenen Kompressor 14 sowie ein Expansionsventil 15 enthält. Sowohl der Elektromotor 13 und somit auch der Kompressor 14 als auch das Expansionsventil 15 können elektrisch be liebig ansteuerbar sein, um die Nutzleistung dieses Kom pressions-Kältemittelkreislaufes 10 zu beeinflussen.With the reference numeral 10 , a refrigerant circuit is characterized, which in addition to an evaporator 11 and a condenser 12 contains a compressor 14 driven by an electric motor 13 and an expansion valve 15 . Both the electric motor 13 and thus the compressor 14 as well as the expansion valve 15 can be electrically controlled as desired in order to influence the useful output of this compression refrigerant circuit 10 .
Ein Kühlmittelkreislauf 20 enthält neben einem luftdurch strömten Wärmetauscher 21 u. a. eine Förderpumpe 22 sowie eine elektrische Zusatzheizung 23 zur Erwärmung des Kühl mittels. Insbesondere dient der Kühlmittelkreislauf 20 zur Kühlung bzw. Temperierung einer Fahrzeug-Antriebsein heit 24, deren Bestandteile u. a. ein Fahrzeug-Elektromo tor 24a sowie eine Fahrzeug-Batterie 24b sind.In addition to a heat exchanger 21 through which air flows, a coolant circuit 20 contains, inter alia, a feed pump 22 and an additional electrical heater 23 for heating the coolant. In particular, the coolant circuit 20 is used for cooling or temperature control of a vehicle drive unit 24 , the components of which include a vehicle electromotive gate 24 a and a vehicle battery 24 b.
Der luftdurchströmte Verdampfer 11, der luftdurchströmte Kondensator 12, sowie der luftdurchströmte Wärmetauscher 21 sind Bestandteil der in ihrer Gesamtheit mit 30 be zeichneten Klimaanlage eines Elektrofahrzeuges. Weitere Elemente dieser Klimaanlage sind zwei Luftkanäle 31a, 31b, die über Klappen 32a, 32b gesteuert entweder im Fahrzeug-Innenraum (Pfeil 33) oder in der Umgebung (Pfeil 34) münden. Stromauf der Klappe 32a sind im Kondensator-Luft kanal 31a der Kondensator 12 sowie der Wärmetauscher 21 angeordnet, während sich stromauf der Klappe 32b im Verdampfer-Luftkanal 31b der Verdampfer 11 befindet. Stromauf des Verdampfers 11 bzw. des Kondensators 12 ver laufen die Luftkanäle 31a, 31b im wesentlichen nebenein ander und vereinigen sich zu einem Ansaugkanal 35, in dem ein einziges, die beiden Luftkanäle 31a, 31b versorgendes Luftstrom-Fördergebläse 36 angeordnet ist. The air-flowed evaporator 11 , the air-flowed condenser 12 , and the air-flowed heat exchanger 21 are part of the air conditioning system of an electric vehicle, which in its entirety is 30 . Other elements of this air conditioning system are two air channels 31 a, 31 b, which, controlled by flaps 32 a, 32 b, open either in the vehicle interior (arrow 33 ) or in the environment (arrow 34 ). Upstream of the flap 32 a in the condenser air channel 31 a, the condenser 12 and the heat exchanger 21 are arranged, while upstream of the flap 32 b in the evaporator air channel 31 b, the evaporator 11 is located. Upstream of the evaporator 11 and the condenser 12 ver run the air channels 31 a, 31 b essentially next to each other and combine to form an intake duct 35 in which a single air flow conveying fan 36, which supplies the two air channels 31 a, 31 b, is arranged .
Fig. 1 zeigt die Verhältnisse beim Kühlen des Fahrzeug-In nenraumes 33. Der Kältemittelkreislauf 10 ist in Be trieb, so daß der vom Gebläse 36 geförderte Luftstrom im Luftkanal 31b am Verdampfer 11 abgekühlt wird und ent sprechend der Stellung der Klappe 32b in den Fahrzeug-In nenraum 33 gelangt. Gleichzeitig muß jedoch nicht nur die Abwärme des Kältemittelkreislaufes 10, sondern auch die Abwärme der Fahrzeug-Antriebseinheit 24 abgeführt werden. Diese Abwärme nimmt der ebenfalls vom Gebläse 36 geför derte, im Luftkanal 31a geführte Luftstrom am Kondensator 12 sowie am Wärmetauscher 21 auf. Entsprechend der Stel lung der Klappe 32a gelangt dieser Luftstrom als Abluft strom in die Umgebung 34. Fig. 1 shows the conditions when cooling the vehicle interior 33 . The refrigerant circuit 10 is in operation, so that the air flow conveyed by the blower 36 in the air duct 31 b is cooled on the evaporator 11 and accordingly the position of the flap 32 b enters the vehicle interior space 33 . At the same time, however, not only the waste heat from the refrigerant circuit 10 , but also the waste heat from the vehicle drive unit 24 must be removed. This waste heat is also taken up by the fan 36 , in the air duct 31 a led air flow at the condenser 12 and at the heat exchanger 21 . Corresponding to the position of the flap 32 a, this air stream passes as exhaust air stream into the environment 34
Fig. 2 zeigt die Verhältnisse bei der Beheizung des Fahr zeug-Innenraumes. Entsprechend der andersartigen Stellung der Klappe 32a gelangt hierbei der im Kondensator-Luftka nal 31a geführte Luftstrom in den Fahrzeug-Innenraum 33. Wie bereits oben erläutert, wurde dieser Luftstrom am Kondensator 12 sowie am Wärmetauscher 21 erwärmt. Gleich zeitig wird der im Verdampfer-Luftkanal 31b geführte, am Verdampfer 11 abgekühlte Luftstrom entsprechend der Stel lung der Klappe 32b in die Umgebung 34 abgeführt. Der so mit auch bei Beheizung des Fahrzeug-Innenraumes betrie bene Kältemittelkreislauf 10 arbeitet hier als Wärme pumpe. Fig. 2 shows the conditions when heating the vehicle interior. Corresponding to the different position of the flap 32 a, the air flow guided in the condenser air channel 31 a passes into the vehicle interior 33 . As already explained above, this air flow was heated at the condenser 12 and at the heat exchanger 21 . At the same time the led in the evaporator air duct 31 b, cooled at the evaporator 11 air flow corresponding to the Stel development of the flap 32 b in the environment 34 is discharged. The so operated with heating of the vehicle interior Bene refrigerant circuit 10 works here as a heat pump.
Fig. 2 zeigt weiterhin eine modifizierte Gestaltung des Ansaugkanales 35. Eine Umschaltklappe 37 verschließt hierbei einen in der Umgebung mündenden Frischluft-An saugkanal 35a und gibt einen im Fahrzeug-Innenraum 33 mündenden Umluft-Ansaugkanal 35b frei. Hierbei arbeitet die Klimaanlage 30 somit im bekannten Umluftbetrieb. Fig. 2 further shows a modified design of the intake passage 35th A changeover flap 37 closes a fresh air intake duct 35 a that opens into the surroundings and releases a recirculated air intake duct 35 b that opens into the vehicle interior 33 . The air conditioning system 30 thus operates in the known recirculation mode.
Bei der Variante nach Fig. 3 hingegen ist der sog. re heat-Betrieb möglich. Stromab des Verdampfers 11 sowie stromauf des Kondensators 12 ist ein von einer Klappe 38a verschließbarer Luftübertritt 39 vom Luftkanal 31b zum Luftkanal 31a vorgesehen. Eine weitere Klappe 38b ver schließt direkt stromab des Fördergebläses 36 den Konden sator-Luftkanal 31a. Somit gelangt der vom Gebläse 36 ge förderte Luftstrom vollständig über den Verdampfer 11 und wird hierbei abgekühlt und entfeuchtet. Anschließend wird dieser getrocknete Luftstrom über den Luftübertritt 39 in den Luftkanal 31a geleitet und gelangt über den Kondensa tor 12 sowie den Wärmetauscher 21 in den Fahrzeug-Innen raum 33. Der Fahrzeug-Innenraum wird hierbei mit getrock neter Luft beheizt, gleichzeitig wird wie bereits im oben erläuterten Heizbetrieb die Fahrzeug-Antriebseinheit 24 über den Kühlmittelkreislauf 20 abgekühlt.In the variant of FIG. 3, however, the so-called. Is re-heat operation possible. Downstream of the evaporator 11 and upstream of the condenser 12 , an air passage 39 , which can be closed by a flap 38 a, is provided from the air duct 31 b to the air duct 31 a. Another flap 38 b ver closes the condenser air duct 31 a directly downstream of the delivery fan 36 . Thus, the air flow conveyed by the fan 36 passes completely through the evaporator 11 and is cooled and dehumidified in the process. This dried air flow is then passed through the air passage 39 into the air duct 31 a and passes through the capacitor 12 and the heat exchanger 21 into the vehicle interior 33 . The vehicle interior is heated with dried air, at the same time the vehicle drive unit 24 is cooled via the coolant circuit 20 , as already explained in the heating mode explained above.
Sämtliche Klappen 32a, 32b, 37, 38a, 38b können selbst verständlich in einer einzigen Klimaanlage 30 installiert sein und den jeweiligen Erfordernissen entsprechend posi tioniert werden. Die gezeigte Klimaanlage stellt somit eine energetisch und aus Sicht des Nutzen-Aufwand-Ver hältnisses sinnvolle Weiterentwicklung bekannter Klimaan lagen unter Berücksichtigung aller möglichen Betriebs fälle dar, wobei ein maximaler Komfort realisiert werden kann, indem die Heizwirkung bzw. Kühlwirkung je nach Wunsch sofort zur Verfügung steht. Da der Kältemittelkreislauf 10 auch im Wärmepumpenbetrieb arbeiten kann und da die Abluft des Kühlmittelkreislaufes 20 vollständig zur Be heizung des Fahrzeug-Innenraumes genutzt werden kann, werden die einzelnen Komponenten der Klimaanlage 30 auf rationellste Weise ausgenutzt. Die gezeigte Klimaanlage zeichnet sich darüber hinaus durch eine geringe elektri sche Energieaufnahme sowie ein geringes Systemgewicht aus. Auch der Bauaufwand ist aufgrund des einzigen För dergebläses 36 äußerst gering. Dies ermöglicht einen kom pakten und wartungsfreundlichen Aufbau der gezeigten Kli maanlage 30. Dabei sind neben den gezeigten Ausführungs beispielen auch Abwandlungen insbesondere konstruktiver Art möglich, die unter den Inhalt der Patentansprüche fallen.All flaps 32 a, 32 b, 37 , 38 a, 38 b can of course be installed in a single air conditioning system 30 and be positioned according to the respective requirements. The air conditioning system shown thus represents an energetic and sensible further development of known air conditioning systems from the point of view of the cost-benefit ratio, taking into account all possible operating cases, and maximum comfort can be achieved by the heating effect or cooling effect being immediately available as desired stands. Since the refrigerant circuit 10 can also work in the heat pump mode and since the exhaust air from the coolant circuit 20 can be used completely for heating the vehicle interior, the individual components of the air conditioning system 30 are used in the most rational manner. The air conditioning system shown is also characterized by a low electrical energy consumption and a low system weight. The construction effort is extremely low due to the single För derbläses 36 . This enables the air-conditioning system 30 shown to be compact and easy to maintain. In addition to the exemplary embodiments shown, modifications, in particular of a constructive nature, are also possible, which fall under the content of the claims.
