Description
Die vorliegende Erfindung betrifft ein Abwärmerückgewinnungssystem für eine Brennkraftmaschine, aufweisend einen in einer Abgasleitung der Brennkraftmaschine eingeschalteten Wärmetauscher, der Teil eines Arbeitsfluidkreislaufs mit zumindest einer Expansionsmaschine, einem Kondensator und einer Fluidpumpe ist.

Ein derartiges Abwärmerückgewinnungssystem ist aus der
Der Erfindung liegt die Aufgabe zu Grunde, ein Abwärmerückgewinnungssystem bereitzustellen, bei dem eine Druckregelung in dem Arbeitsfluidkreislauf des Abwärmerückgewinnungssystems möglich ist. The invention has for its object to provide a waste heat recovery system in which a pressure control in the working fluid circuit of the waste heat recovery system is possible.
Offenbarung der Erfindung Disclosure of the invention
Vorteile der Erfindung Advantages of the invention
Diese Aufgabe wird dadurch gelöst, dass der Arbeitsfluidkreislauf einen Ausgleichsbehälter aufweist, und dass der Ausgleichsbehälter druckluftbeaufschlagt ist. Dieser Ausgestaltung liegt die Erkenntnis zu Grunde, dass das Arbeitsfluid des Arbeitsfluidkreislaufs in dem Kondensator vollständig verflüssigt werden muss, um eine Kavitation nach dem Kondensator zu vermeiden und um den für die nachfolgende Verdichtung durch die Fluidpumpe notwendigen flüssigen Aggregatzustand zu gewährleisten. Hierzu muss das Temperaturniveau in dem Kondensator unterhalb des Siedepunktes des Fluids liegen. Der Siedepunkt ist aber abhängig vom Arbeitsfluid sowie dem jeweiligen Druckniveau und steigt mit dem Druck an. Kann von dem an dem Kondensator angeschlossenen Kühlkreislauf kein Temperaturniveau unterhalb der Siedetemperatur des Arbeitsfluids bereitgestellt werden, besteht die Möglichkeit, den Druck im Niederdruckbereich des Systems, das heißt im Bereich nach der Expansion in der Expansionsmaschine und vor der Verdichtung in der Fluidpumpe zu erhöhen, mit dem Ziel, die Siedetemperatur des Arbeitsfluids anzuheben. Wird das Abwärmerückgewinnungssystem bei Überdruck gegenüber der Umgebung betrieben, muss das Überdruckniveau in allen Betriebszuständen aufrechterhalten werden. Da sich das Fluidvolumen im Niederdruckbereich in Folge unterschiedlicher Betriebszustände fortwährend ändert, stellt sich ohne eine Druckregelvorrichtung der Kondensationsdruck abhängig vom Fluidvolumen ein. Der Druck schwankt hierbei zwischen dem zur Kondensation notwendigen unteren Druckniveau bei minimalem Füllstand im Ausgleichsbehälter und einem höheren Druck. Das untere Druckniveau ist jedoch ein wesentlicher Einflussfaktor des Wirkungsgrades und sollte daher unabhängig von dem Betriebspunkt und möglichst gering sein. Dadurch, dass der Ausgleichsbehälter druckluftbeaufschlagt ist, besteht eine Möglichkeit, das Druckniveau zu regeln, Fluidvolumenänderungen im Niederdruckbereich des Arbeitsfluidkreislaufs zu kompensieren und somit eine für die Kondensation robuste und gleichzeitig wirkungsgradoptimale Druckeinstellung zu ermöglichen. This object is achieved in that the working fluid circuit has a surge tank, and that the expansion tank is pressurized air. This embodiment is based on the finding that the working fluid of the working fluid circuit in the condenser must be completely liquefied in order to avoid cavitation after the condenser and to ensure the necessary for the subsequent compression by the fluid pump liquid state. For this purpose, the temperature level in the condenser must be below the boiling point of the fluid. The boiling point, however, depends on the working fluid and the respective pressure level and increases with the pressure. If no temperature level below the boiling temperature of the working fluid can be provided by the cooling circuit connected to the condenser, it is possible to increase the pressure in the low-pressure region of the system, ie in the region after expansion in the expansion machine and before compression in the fluid pump the goal of raising the boiling temperature of the working fluid. If the waste heat recovery system is operated with overpressure relative to the environment, the overpressure level must be maintained in all operating conditions. Since the fluid volume continuously changes in the low-pressure region as a result of different operating states, without a pressure control device, the condensation pressure sets depending on the fluid volume. In this case, the pressure fluctuates between the lower pressure level necessary for condensation with a minimum fill level in the expansion tank and a higher pressure. However, the lower pressure level is a significant influencing factor of the efficiency and should therefore be independent of the operating point and as low as possible. The fact that the expansion tank is pressurized air, there is a way to regulate the pressure level, to compensate for fluid volume changes in the low pressure region of the working fluid circuit and thus allow a robust for the condensation and at the same time efficiency optimal pressure setting.
In Weiterbildung der Erfindung weist die Druckluftzuführung eine Druckluftquelle auf, wobei die Druckluftquelle ein Luftpresser ist. Der Luftpresser kann als zusätzliche Komponente an der Brennkraftmaschine angebaut sein, ist aber bevorzugt ein Luftpresser, der schon an der Brennkraftmaschine vorhanden ist um beispielsweise Druckluft für eine druckluftbetriebene oder druckluftunterstützte Bremsanlage eines Fahrzeugs, in das die Brennkraftmaschine eingebaut ist, zu liefern. Insbesondere bei einem schon vorhandenen Luftpresser stellt der Gegenstand der Erfindung eine kostengünstige, gut in ein Fahrzeug integrierbare und robuste Möglichkeit dar, den Druck im Niederdruckbereich eines Abwärmerückgewinnungssystems zu regeln. Durch die Möglichkeit der Druckregelung ergeben sich Vorteile in Bezug auf die Robustheit gegenüber Nachverdampfen bzw. Kavitation im Niederdruckbereich des Arbeitsfluidkreislaufs und in Bezug auf den Wirkungsgrad des Abwärmerückgewinnungssystems.In a further development of the invention, the compressed air supply to a compressed air source, wherein the compressed air source is an air compressor. The air compressor may be mounted as an additional component to the internal combustion engine, but is preferably an air compressor, which is already present on the internal combustion engine to deliver, for example, compressed air for a compressed air-driven or compressed air-assisted brake system of a vehicle, in which the internal combustion engine is installed. Particularly in the case of an already existing air compressor, the subject matter of the invention represents a cost-effective and robust possibility that can be well integrated into a vehicle and regulates the pressure in the low-pressure region of a waste heat recovery system. The possibility of pressure control provides advantages in terms of ruggedness against post-evaporation or cavitation in the low-pressure region of the working fluid circuit and in terms of the efficiency of the waste heat recovery system.
In Weiterbildung der Erfindung ist der Luftpresser über ein Schutzventil, insbesondere ein Vierkreisschutzventil, mit dem Ausgleichsbehälter verschaltet. Diese Ausgestaltung stellt sicher, dass im Falle eines Lecks oder eines Defekts in der Druckluftleitung zu dem Abwärmerückgewinnungssystem oder dem Ausgleichsbehälter das weitere Druckluftsystem unverändert funktionstüchtig ist. Dies ist insbesondere bei Anschluss eines Bremssystems an den Luftpresser von Vorteil bzw. notwendig. Über ein solches Vierkreisschutzventil sind beispielsweise eine erste Betriebsbremse, eine zweite Betriebsbremse und eine Feststellbremse über drei getrennte Druckluftleitungen mit dem Luftpresser verbunden. Ein vierter Ausgang des Vierkreisschutzventils ist mit einem Nebenverbraucherkreis verbunden, von dem aus auch die erfindungsgemäße Druckluftbeaufschlagung des Ausgleichsbehälters erfolgt. In a further development of the invention, the air compressor is connected via a protective valve, in particular a four-circuit protection valve, with the expansion tank. This embodiment ensures that in the case of a leak or a defect in the compressed air line to the waste heat recovery system or the expansion tank, the further compressed air system is unchanged functional. This is particularly advantageous or necessary when connecting a brake system to the air compressor. About such a four-circuit protection valve, for example, a first service brake, a second service brake and a parking brake via three separate compressed air lines connected to the air compressor. A fourth output of the four-circuit protection valve is connected to a secondary consumer circuit, from which also takes place according to the invention from the pressurization of the expansion tank.
In weiterer Ausgestaltung der Erfindung ist in die Druckluftzuführung zu dem Ausgleichsbehälter oder auch eingangsseitig in den Ausgleichsbehälter selbst ein Rückschlagventil eingesetzt. Dieses Rückschlagventil stellt sicher, dass in dem Ausgleichsbehälter immer ein definierter Mindestdruck herrscht. Das Rückschlagventil kann als mechanisches Rückschlagventil mit einem definiert eingestellten Öffnungsdruck und Schließdruck sein oder aber in weiterer Ausgestaltung elektrisch angesteuert sein. Dabei kann das elektrisch angesteuerte Rückschlagventil von einer entsprechenden Hardware und Software in Abhängigkeit von Betriebszuständen der Brennkraftmaschine und/oder des Abwärmerückgewinnungssystems angesteuert werden. In a further embodiment of the invention, a check valve is used in the compressed air supply to the expansion tank or on the input side in the expansion tank itself. This check valve ensures that there is always a defined minimum pressure in the expansion tank. The check valve may be as a mechanical check valve with a defined set opening pressure and closing pressure or be electrically controlled in another embodiment. In this case, the electrically controlled non-return valve can be controlled by a corresponding hardware and software depending on operating conditions of the internal combustion engine and / or the waste heat recovery system.
In weiterer Ausgestaltung der Erfindung ist in die Druckluftzuführung oder den Ausgleichsbehälter ein Überdruckventil für Druckluft eingesetzt, dass bei Erhöhung des Drucks über einen vorgegebenen Maximalwert Druckluft in die Umgebung absteuert. Diese Absteuerung kann erforderlich sein, wenn sich das Volumen des Arbeitsfluids in dem Ausgleichsbehälter vergrößert. In a further embodiment of the invention, a pressure relief valve for compressed air is used in the compressed air supply or the expansion tank, that absteuert compressed air in the environment when increasing the pressure above a predetermined maximum value. This shutdown may be required as the volume of working fluid in the surge tank increases.
In Weiterbildung der Erfindung ist in die Druckluftzuführung zu dem Ausgleichsbehälter ein Druckluftspeicher eingebaut. Der Druckluftspeicher ermöglicht ein von dem Luftpresser entkoppeltes Regeln der Druckluftzufuhr zu dem Ausgleichsbehälter. So kann gewährleistet werden, dass nach einem Abstellen eines Fahrzeugs, in dem eine Brennkraftmaschine mit dem erfindungsgemäßen Abwärmerückgewinnungssystem verbaut ist, noch genügend Druckluft vorhanden ist, um den Systemdruck in dem Abwärmerückgewinnungssystem in der ersten Zeit nach dem Abstellen der Brennkraftmaschine zu erhalten bzw. bedarfsgerecht zu regeln. In a further development of the invention, a compressed air reservoir is installed in the compressed air supply to the expansion tank. The compressed air reservoir allows a decoupled from the air compressor rules of compressed air supply to the expansion tank. So it can be ensured that after stopping a vehicle in which an internal combustion engine is installed with the waste heat recovery system according to the invention, there is still enough compressed air to maintain the system pressure in the waste heat recovery system in the first time after stopping the engine or to demand regulate.
In Weiterbildung der Erfindung weist der Ausgleichsbehälter eine Trennmembran zwischen einer Arbeitsfluidkammer und einer Druckluftkammer auf. Die Trennmembran stellt eine konsequente Trennung des Arbeitsfluids von der Druckluft sicher. Dabei ist wiederum in weiterer Ausgestaltung der Erfindung die Trennmembran aus einem dauerelastischen, hitzebeständigen und druckfesten Werkstoff gefertigt. In development of the invention, the expansion tank on a separation membrane between a working fluid chamber and a compressed air chamber. The separation membrane ensures a consistent separation of the working fluid from the compressed air. Again, in a further embodiment of the invention, the separation membrane is made of a permanently elastic, heat-resistant and pressure-resistant material.
