Abstract
Description
Die Erfindung betrifft eine Temperiereinrichtung für einen Kraftwagen.The invention relates to a tempering device for a motor vehicle.
Aus dem allgemeinen Stand der Technik sind Elektrofahrzeuge sowie Hybrid-Fahrzeuge bekannt. Diese umfassen wenigstens einen Elektromotor, mittels welchem das Hybrid-Fahrzeug bzw. das Elektrofahrzeug antreibbar ist. Zum Betreiben des Elektromotors wird dieser mit elektrischem Strom aus einer elektrischen Speichereinrichtung, insbesondere aus einer Batterie, des Hybrid-Fahrzeugs bzw. des Elektrofahrzeugs versorgt.From the general state of the art electric vehicles and hybrid vehicles are known. These include at least one electric motor, by means of which the hybrid vehicle or the electric vehicle is drivable. To operate the electric motor, it is supplied with electric current from an electrical storage device, in particular from a battery, the hybrid vehicle or the electric vehicle.
Elektrische Speichereinrichtungen weisen einen Betriebstemperaturbereich auf, innerhalb welchem sie effizient betrieben werden, d. h. mit elektrischem Strom geladen oder entladen werden können. Dabei sind die elektrischen Speichereinrichtungen insbesondere vor einer Überhitzung und daraus resultierenden Beschädigungen zu schützen.Electrical storage devices have an operating temperature range within which they operate efficiently, i. H. can be charged or discharged with electric current. In this case, the electrical storage devices are to be protected in particular from overheating and resulting damage.
Des Weiteren hat es sich gezeigt, dass zum Beheizen von Fahrgasträumen der Elektrofahrzeuge bzw. der Hybrid-Fahrzeuge elektrische Energie aufzuwenden ist, da keine oder nicht genügend Abwärmezur Verfügung steht, welche zum Beheizen der Fahrgasträume genutzt werden könnte. Die Verwendung von elektrischer Energie zum Beheizen hat jedoch starke Auswirkung auf die Reichweite der Elektrofahrzeuge bzw. Hybrid-Fahrzeuge.Furthermore, it has been found that electrical energy is needed to heat passenger compartments of the electric vehicles or hybrid vehicles because there is no or not enough waste heat available, which could be used to heat the passenger compartments. The use of electrical energy for heating, however, has a strong impact on the range of electric vehicles or hybrid vehicles.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Temperiereinrichtung für einen Kraftwagen, insbesondere eines Hybrid-Fahrzeugs oder eines Elektrofahrzeugs, bereitzustellen, welche ein energieeffizientes Temperieren der elektrischen Speichereinrichtung und des Fahrgastraums auf unaufwändige Weise ermöglicht.It is therefore an object of the present invention to provide a tempering device for a motor vehicle, in particular a hybrid vehicle or an electric vehicle, which enables an energy-efficient temperature control of the electrical storage device and the passenger compartment in an inefficient manner.
Diese Aufgabe wird durch eine Temperiereinrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den weiteren Ansprüchen angegeben.This object is achieved by a tempering device having the features of patent claim 1. Advantageous embodiments with expedient developments of the invention are specified in the further claims.
Eine erfindungsgemäße Temperiereinrichtung für einen Kraftwagen, insbesondere eines Hybrid-Fahrzeugs oder eines Elektrofahrzeugs, umfasst wenigstens eine Wärmepumpe mit zumindest einem Verdichter, zumindest einem Kondensator, zumindest einer Drossel und mit zumindest einem Verdampfer. Mittels der Wärmepumpe ist ein Fahrgastraum des Kraftwagens beheizbar. Der Wärmepumpe ist dabei wenigstens eine elektrische Speichereinrichtung des Kraftwagens zugeordnet, welche mittels der Wärmepumpe kühlbar ist. Dies bedeutet, dass mittels der Wärmepumpe Wärmeenergie von der elektrischen Speichereinrichtung abgeführt werden kann, so dass die elektrische Speichereinrichtung gekühlt wird. Die von der elektrischen Speichereinrichtung abgeführte Wärme kann dem Fahrgastraum zugeführt werden, um diesen zu beheizen.A tempering device according to the invention for a motor vehicle, in particular a hybrid vehicle or an electric vehicle, comprises at least one heat pump with at least one compressor, at least one condenser, at least one throttle and with at least one evaporator. By means of the heat pump, a passenger compartment of the motor vehicle can be heated. The heat pump is associated with at least one electrical storage device of the motor vehicle, which can be cooled by means of the heat pump. This means that by means of the heat pump thermal energy can be dissipated by the electrical storage device, so that the electrical storage device is cooled. The heat dissipated by the electric storage device may be supplied to the passenger compartment to heat it.
Dadurch ist eine effiziente Kühlung der elektrischen Speichereinrichtung sowie ein effizientes Beheizen des Fahrgastraums auf einfache Weise mit einer nur sehr geringen Teileanzahl ermöglicht, da die Wärmepumpe, insbesondere ihr Verdichter, sowohl zum Kühlen der elektrischen Speichereinrichtung als auch zum Erwärmen des Fahrgastraums genutzt wird. Das Aufwenden von zusätzlicher Energie, insbesondere elektrischer Energie, zum Beheizen des Fahrgastraums und/oder zum Kühlen der elektrischen Speichereinrichtung kann vermieden oder zumindest gering gehalten werden.As a result, efficient cooling of the electrical storage device and efficient heating of the passenger compartment is made possible in a simple manner with only a very small number of parts, since the heat pump, in particular its compressor, is used both for cooling the electrical storage device and for heating the passenger compartment. The expenditure of additional energy, in particular electrical energy, for heating the passenger compartment and / or for cooling the electrical storage device can be avoided or at least minimized.
Daraus resultiert eine sehr hohe Reichweite des Kraftwagens, über die der Kraftwagen beispielsweise mittels wenigstens eines Elektromotors elektrisch angetrieben werden kann. Hierbei kann die elektrische Speichereinrichtung, welche beispielsweise als Batterie und insbesondere als Hochvolt-Batterie ausgebildet ist, zum Versorgen des Elektromotors mit elektrischem Strom genutzt werden.This results in a very high range of the motor vehicle, via which the motor vehicle can be electrically driven, for example by means of at least one electric motor. Here, the electrical storage device, which is designed for example as a battery and in particular as a high-voltage battery, be used to supply the electric motor with electric power.
Mittels der Wärmepumpe kann die elektrische Speichereinrichtung auch in einem vorteilhaften Temperaturbereich gehalten werden, in dem die elektrische Speichereinrichtung effizient betreibbar ist. Mittels der Temperiereinrichtung kann somit sowohl thermische als auch elektrische Energie effizient genutzt werden, um den Kraftwagen zu betreiben. Dadurch, dass die Wärmepumpe sowohl zum Kühlen der elektrischen Speichereinrichtung als auch zum Beheizen des Fahrgastraums verwendet wird, können auch das Gewicht und die Kosten des Kraftwagens gering gehalten werden.By means of the heat pump, the electrical storage device can also be kept in an advantageous temperature range in which the electrical storage device can be operated efficiently. By means of the tempering device can thus be used efficiently both thermal and electrical energy to operate the car. The fact that the heat pump is used both for cooling the electrical storage device as well as for heating the passenger compartment, the weight and the cost of the motor vehicle can be kept low.
