Ein derartiges Fahrzeug umfasst einen Elektroantriebsmotor und eine für den Betrieb dieses Elektroantriebsmotors die erforderliche elektrische Energie bereitstellende Quelle elektrischer Energie, beispielsweise eine wiederaufladbare Batterie.The present invention relates to a heating / cooling system for an electromotive vehicle according to the preamble of claim 1. Such a vehicle comprises an electric drive motor and a source of electrical energy, such as a rechargeable battery, for providing that electric drive motor with the required electrical energy.
Derartige Quellen elektrischer Energie, insbesondere Batterien, weisen einen Temperaturbereich auf, in welchem sie elektrische Energie mit optimaler Effizienz bereitstellen können. Diese Temperatur liegt beispielsweise im Bereich von 30 bis 35°C. Zu hohe oder zu niedrige Temperaturen führen zu Effizienzeinbußen und mithin bei elektromotorisch betriebenen Fahrzeugen zu bisweilen deutlich verringerten Reichweiten.Such sources of electrical energy, especially batteries, have a temperature range in which they can provide electrical energy with optimal efficiency. This temperature is for example in the range of 30 to 35 ° C. Too high or too low temperatures lead to loss of efficiency and thus in motorized vehicles at sometimes significantly reduced ranges.

B. an internal combustion engine, are present, it is provided that the refrigerant circuit in the heating mode and in the cooling mode is operable.
Insbesondere um den Heizbetrieb und den Kühlbetrieb realisieren zu können, also das System sowohl als Klimaanlage als auch als Wärmepumpe betreiben zu können, wird weiter vorgeschlagen, dass der Kältemittelkreislauf eine erste Expansionsanordnung in Strömungsrichtung des Kältemittels im Kältemittelkreislauf vor der ersten Wärmetauscheranordnung und eine zweite Expansionsanordnung in Strömungsrichtung nach der ersten Wärmetauscheranordnung umfasst.In particular, in order to realize the heating and cooling operation, so to operate the system both as air conditioning and heat pump, it is further proposed that the refrigerant circuit is a first expansion arrangement in the flow direction of the refrigerant in the refrigerant circuit before the first heat exchanger assembly and a second expansion assembly in Flow direction after the first heat exchanger assembly comprises.
Zum Umschalten zwischen den beiden Betriebsarten Heizen und Kühlen kann vorgesehen sein, dass der Kältemittelkreislauf eine erste Ventilanordnung zum wahlweisen Freigeben und Sperren der ersten Expansionsanordnung und eine zweite Ventilanordnung zum wahlweisen Freigeben und Sperren der zweiten Expansionsanordnung umfasst. Durch entsprechende Schaltung der Ventilanordnungen kann somit zwischen dem Heizbetrieb und dem Kühlbetrieb gewählt bzw. umgeschaltet werden.For switching between the two operating modes heating and cooling it can be provided that the refrigerant circuit comprises a first valve arrangement for selectively enabling and disabling the first expansion arrangement and a second valve arrangement for selectively enabling and disabling the second expansion arrangement. By appropriate circuit of the valve assemblies can thus be selected or switched between the heating and cooling operation.
Um bei zu niedriger Temperatur der Quelle elektrischer Energie für eine Erwärmung derselben sorgen zu können, beispielsweise auch dann, wenn das Heiz/Kühl-System grundsätzlich im Kühlbetrieb betrieben wird, wird vorgeschlagen, dass die wenigstens eine weitere Wärmetauscheranordnung eine zweite Wärmetauscheranordnung zur Übertragung von Wärme von dem im Kältemittelkreislauf zirkulierenden Kältemittel auf einen zur Quelle elektrischer Energie zu leitenden Luftstrom umfasst.In order to ensure at a low temperature of the source of electrical energy for heating the same, for example, even if the heating / cooling system is basically operated in cooling mode, it is proposed that the at least one further heat exchanger assembly, a second heat exchanger assembly for Transfer of heat from the refrigerant circulating in the refrigerant circuit to a flow of air to be supplied to the source of electrical energy.
Dazu kann beispielsweise vorgesehen sein, dass die zweite Wärmetauscheranordnung in Strömungsrichtung des Kältemittels im Kältemittelkreislauf stromaufwärts der ersten Expansionsanordnung angeordnet ist.For this purpose, it can be provided, for example, that the second heat exchanger arrangement is arranged in the flow direction of the refrigerant in the refrigerant circuit upstream of the first expansion arrangement.
Um bei Integration dieser zweiten Wärmetauscheranordnung in den Kältemittelkreislauf vermittels der ersten Ventilanordnung zwischen dem Heizbetrieb und dem Kühlbetrieb umschalten zu können, wird weiter vorgeschlagen, dass der Kältemittelkreislauf einen durch die erste Ventilanordnung freigebbaren und sperrbaren ersten Teilströmungsweg von der Verdichteranordnung zur ersten Wärmetauscheranordnung umfasst, wobei im ersten Teilströmungsweg die zweite Wärmetauscheranordnung und die erste Expansionsanordnung angeordnet sind, und einen durch die erste Ventilanordnung freigebbaren und sperrbaren ersten Bypassströmungsweg umfasst, wobei der erste Bypassströmungsweg unter Umgehung der zweiten Wärmetauscheranordnung und der ersten Expansionsanordnung von der Verdichteranordnung zur ersten Wärmetauscheranordnung führt.In order to be able to switch between the heating mode and the cooling mode by integrating this second heat exchanger arrangement into the refrigerant circuit by means of the first valve arrangement, it is further proposed that the refrigerant circuit comprises a first partial flow path that can be opened and shut off by the first valve arrangement from the compressor arrangement to the first heat exchanger arrangement first partial flow path, the second heat exchanger assembly and the first expansion assembly are arranged, and comprising a releasable by the first valve assembly and lockable first bypass flow path, the first bypass flow path, bypassing the second heat exchanger assembly and the first expansion assembly from the compressor assembly leads to the first heat exchanger assembly.
Eine Kühlung der Quelle elektrischer Energie, beispielsweise auch dann, wenn der Fahrzeuginnenraum zu heizen ist, kann dadurch erreicht werden, dass die wenigstens eine weitere Wärmetauscheranordnung eine dritte Wärmetauscheranordnung zum Übertragen von Wärme von einem zur Quelle elektrischer Energie zu leitenden Luftstrom auf das im Kältemittelkreislauf zirkulierende Kältemittel umfasst.A cooling of the source of electrical energy, for example, even if the vehicle interior is to be heated, can be achieved in that the at least one further heat exchanger assembly, a third heat exchanger assembly for transferring heat from an air stream to the source of electrical energy to the circulating in the refrigerant circuit Includes refrigerant.
Hierzu kann beispielsweise vorgesehen sein, dass die dritte Wärmetauscheranordnung in Strömungsrichtung des Kältemittels im Kältemittelkreislauf stromabwärts der zweiten Expansionsanordnung angeordnet ist.For this purpose, it can be provided, for example, that the third heat exchanger arrangement is arranged in the flow direction of the refrigerant in the refrigerant circuit downstream of the second expansion arrangement.
Bei Integration dieser dritten Wärmetauscheranordnung in den Kältemittelkreislauf kann das Umschalten zwischen den beiden vorangehend angesprochenen Betriebsarten Heizen und Kühlen dadurch leicht realisiert werden, dass der Kältemittelkreislauf einen durch die zweite Ventilanordnung freigebbaren und sperrbaren zweiten Teilströmungsweg von der ersten Wärmetauscheranordnung zur Verdichteranordnung umfasst, wobei im zweiten Teilströmungsweg die zweite Expansionsanordnung und die dritte Wärmetauscheranordnung angeordnet sind, und einen durch die zweite Ventilanordnung freigebbaren und sperrbaren zweiten Bypassströmungsweg umfasst, wobei der zweite Bypassströmungsweg unter Umgehung der zweiten Expansionsanordnung und der dritten Wärmetauscheranordnung von der ersten Wärmetauscheranordnung zur Verdichteranordnung führt.When integrating this third heat exchanger arrangement in the refrigerant circuit switching between the two above-mentioned modes of heating and cooling can be easily realized that the refrigerant circuit comprises a releasable by the second valve assembly and lockable second Teilströmungsweg from the first heat exchanger assembly to the compressor assembly, wherein in the second Teilströmungsweg the second expansion arrangement and the third heat exchanger arrangement are arranged, and comprises a second bypass flow path which can be opened and shut off by the second valve arrangement, wherein the second bypass flow path leads from the first heat exchanger arrangement to the compressor arrangement, bypassing the second expansion arrangement and the third heat exchanger arrangement.
Gemäß einem werteren vorteilhaften Aspekt wird vorgeschlagen, dass wenigstens ein Teil des in den Fahrzeuginnenraum einzuleitenden Luftstroms oder/und eines aus dem Fahrzeuginnenraum abzuziehenden Luftstroms zur Quelle elektrischer Energie leitbar ist. Dies bedeutet, dass dann, wenn der in den Fahrzeuginnenraum einzuleitende Luftstrom oder auch die aus dem Fahrzeuginnenraum abzuziehende Luft eine Temperatur aufweist, welche für die Temperierung der Quelle elektrischer Energie geeignet ist, auch diese Luft bzw. dieser Luftstrom zumindest zum Teil genutzt werden kann, um die Quelle elektrischer Energie bei der geeigneten Temperatur zu halten oder auf die geeignete Temperatur zu bringen.According to another advantageous aspect, it is proposed that at least a part of the airflow to be introduced into the vehicle interior and / or an airflow to be withdrawn from the vehicle interior be routable to the source of electrical energy.
