Abstract
Description
Die Erfindung betrifft eine Klimaanlage insbesondere für Fahrzeuge, wobei ein Kühlwasserkreislauf zum Kühlen einer Wärmequelle, wie z. B. einer Batterie eines Hybrid- oder Elektrofahrzeugs vorgesehen ist.The invention relates to an air conditioner, in particular for vehicles, wherein a cooling water circuit for cooling a heat source, such. B. a battery of a hybrid or electric vehicle is provided.
Bei einem Hybrid-Fahrzeug ist es bekannt, die Batterie für den Antrieb des Elektromotors durch einen Wasserkreislauf zu kühlen, wobei das erwärmte Kühlwasser durch Wärmeübertragung mit dem Kältemittel der Klimaanlage gekühlt wird.In a hybrid vehicle, it is known to cool the battery for driving the electric motor by a water circuit, wherein the heated cooling water is cooled by heat transfer with the refrigerant of the air conditioner.
Der Wasserkreislauf
Dieser bekannte Aufbau nach
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung dieser Art zu vereinfachen. Zusätzlich soll die Effizienz der Vorrichtung verbessert werden.The invention has for its object to simplify a device of this kind. In addition, the efficiency of the device is to be improved.
Dies wird erfindungsgemäß dadurch erreicht, dass die Wärmeübertragung zwischen Kältemittel und Kühlmittel (Wasser) an oder in dem im Kältemittelkreis vorhandenen Akkumulator vorgenommen wird.This is inventively achieved in that the heat transfer between refrigerant and coolant (water) is made on or in the existing in the refrigerant circuit accumulator.
Hierdurch wird eine wesentliche Verringerung des apparativen Aufwands erreicht, weil keine gesonderte Leitungsführung mit gesonderten Ventilen erforderlich ist.As a result, a significant reduction in the equipment cost is achieved because no separate wiring with separate valves is required.
Hinzu kommt, dass durch die Wärmeübertragung im oder am Akkumulator eine bessere Anpassung des Kältekreises an die verschiedenen Lastzustände möglich ist.In addition, a better adaptation of the refrigeration circuit to the different load conditions is possible by the heat transfer in or on the accumulator.
Im Einzelnen wird erfindungsgemäß ein Verfahren zum Kühlen eines Kühlmittels eines Kühlmittelkreislaufs einer Abwärme erzeugenden Einrichtung mittels des durch einen Kältemittelkreislauf strömenden Kältemittels vorgesehen, das einen Verdampfer und einen Akkumulator zum Sammeln und Trennen von flüssigem und dampfförmigem Kältemittel durchströmt, wobei die Wärmeübertragung zwischen Kühlmittel des Kühlmittelkreises und Kältemittel des Kältemittelkreises am oder im Akkumulator des Kältemittelkreises vorgenommen wird. Hierbei kann das Kühlmittel von außen in wärmeleitendem Kontakt mit dem Akkumulator die Wärme auf das Kältemittel im Akkumulator oder auf das in den Akkumulator einströmende Kältemittel übertragen. Eine kompaktere Bauform ergibt sich durch eine Wärmeübertragung innerhalb des Akkumulators, wobei das Kühlmittel durch das Kältemittel im Akkumulator geleitet wird.More specifically, according to the present invention, there is provided a method of cooling a refrigerant circuit of a waste heat generating device by means of the refrigerant flowing through a refrigerant circuit passing through an evaporator and an accumulator for collecting and separating liquid and vapor refrigerant, wherein the heat transfer between the refrigerant of the refrigerant circuit and Refrigerant of the refrigerant circuit is performed on or in the accumulator of the refrigerant circuit. In this case, the coolant can transfer the heat from the outside in heat-conducting contact with the accumulator to the refrigerant in the accumulator or to the refrigerant flowing into the accumulator. A more compact design results from a heat transfer within the accumulator, wherein the coolant is passed through the refrigerant in the accumulator.
Das Verfahren kann zum Kühlen der Batterie für den Antrieb eines Elektromotors eines Elektro- oder Hybrid-Fahrzeugs und/oder weiterer elektrischer Bauteile in vorteilhafter Weise verwendet werden. Es ist aber auch möglich, den Kühlmittelkreislauf als Wärmequelle für eine Wärmepumpe zu verwenden, wobei eine Wärmepumpenanlage auch mit dem Kühlmittelkreislauf zum Kühlen einer Batterie und/oder anderer elektrischer Bauteile kombiniert werden kann.The method can be used to cool the battery for driving an electric motor of an electric or hybrid vehicle and / or other electrical components in an advantageous manner. But it is also possible to use the coolant circuit as a heat source for a heat pump, wherein a heat pump system can also be combined with the coolant circuit for cooling a battery and / or other electrical components.
Dem dampfförmigen Kältemittel wird flüssiges Kältemittel zum Einstellen des Verhältnisses von flüssigem zu dampfförmigem Kältemittel zugeführt, wobei vorteilhafter Weise die Erwärmung des Kältemittels durch das warme Kühlmittel vor der Mischung von flüssigem und dampfförmigen Kältemittel vorgenommen wird, um eine höhere Effizienz des Kältemittelkreislaufs zu erreichen.Liquid refrigerant is supplied to the vapor refrigerant for adjusting the ratio of liquid to vapor refrigerant, and it is preferable to heat the refrigerant by the warm refrigerant before mixing liquid and vapor refrigerant to achieve a higher refrigerant cycle efficiency.
Bei einer Vorrichtung umfassend einen Kältemittelkreislauf mit einem Akkumulator und einen Kühlmittelkreislauf mit einer Wärmequelle, bei der das Kühlmittel durch das Kältemittel gekühlt wird, wird erfindungsgemäß ein Wärmeübertrager zum Kühlen des durch den Kühlmittelkreislauf strömenden Kühlmittels vorgesehen, der in dem Akkumulator oder an dem Akkumulator in wärmeleitendem Kontakt mit diesem angeordnet werden kann.In a device comprising a refrigerant circuit with an accumulator and a coolant circuit with a heat source in which the coolant is cooled by the refrigerant, according to the invention a heat exchanger for cooling the coolant flowing through the coolant circuit is provided, which in the accumulator or on the accumulator in thermally conductive Contact with this can be arranged.
