Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Klimaanlage in einem Kraftfahrzeug nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a method for operating an air conditioning system in a motor vehicle according to the closer defined in the preamble of claim 1 Art.
Bei verbrauchsarmen Kraftfahrzeugen, insbesondere bei Fahrzeugen mit direkt einspritzenden Diesel-Brennkraftmaschinen, ist die Fahrzeugheizung häufig nicht mehr in der Lage, den Fahrzeuginnenraum innerhalb einer vertretbaren Zeitdauer ausreichend zu erwärmen. Zur Lösung dieses Problems wird in einem allgemeinen Stand der Technik vorgeschlagen, elektrische Zuheizelemente, die auch als PTC's bezeichnet werden, zu verwenden. Diese belasten jedoch das zum Großteil bereits an seiner Leistungsgrenze betriebene elektrische Bordnetz zusätzlich. Andere Lösungsansätze sehen vor, Brennstoffheizer einzusetzen, die jedoch Kraftstoff verbrauchen und zusätzliche Abgasemissionen erzeugen.at low-consumption motor vehicles, especially in vehicles with Direct injection diesel engines, is the vehicle heater often no longer able to control the vehicle interior within a reasonable amount To heat the time sufficiently. To the solution this problem is proposed in a general state of the art, electric Zuheizelemente, which are also referred to as PTC's to use. These However, this burden a lot already at its power limit operated electrical system additionally. See other solutions to use fuel heaters, but consume fuel and additional Generate exhaust emissions.

Nachteilig an diesen Lösungen ist, dass die Erwärmung der dem Innenraum des Kraftfahrzeugs zugeführten Luft nicht direkt erfolgt, sondern über einen Heizungswärmetauscher im Wärmeträgerkreislauf als Teil des Motorkühlsystems. Aufgrund der thermischen Massen ergibt sich eine hohe Trägheit der Anlage, was die Dynamik beim Aufheizen vermindert und der Verkehrssicherheit abträglich ist.adversely at these solutions is that warming the air supplied to the interior of the motor vehicle does not occur directly, but about a heating heat exchanger in the heat transfer circuit as part of the engine cooling system. Due to the thermal masses results in a high inertia of Plant, which reduces the dynamics during heating and road safety detrimental is.

Nachteilig ist, dass in dem Klimakasten ständig eine hohe Wärmelast eingebracht wird, dass der Heizungswärmetauscher hoher Temperatur- und Druckbelastung widerstehen muss, dass die Verrohrung der Anlage im Fahrzeug komplex und bauraumintensiv ist und dass sich vermeidbare Druckabfälle mit Effizienzminderung einstellen. Die Anlage erfüllt daher nicht die allgemein gültigen Anforderungen an Komplexität, Kosten, Effizienz, Leistungsfähigkeit und Ökologie.adversely is that in the air conditioning box constantly a high heat load is introduced that the heating heat exchanger high temperature and pressure load must withstand that the piping of the plant In the vehicle complex and space-consuming and that is avoidable With pressure drops Adjust efficiency. The plant therefore does not meet the general requirements valid Complexity requirements, Cost, efficiency, performance and ecology.
Aus Gründen der Beschlagfreihaltung der Scheiben wird gemäß den im Stand der Technik beschriebenen Lösungen bei Temperaturen von ca. –4°C und 10°C der eintretende Luftmassenstrom durch die Kälteanlage im Kühlbetrieb abgekühlt und damit getrocknet und danach im Heizungswärmetauscher auf die benötigte Lufttemperatur im sogenannten "Reheat Betrieb" erwärmt. Bei Nutzung des kältemitteldurchströmten Wärmetauschers zum Heizen kann die Funktion des Abkühlens und damit des Trocknens nicht gleichzeitig ausgeführt werden.Out establish the fogging of the discs is according to those in the prior art described solutions at temperatures of about -4 ° C and 10 ° C entering the Air mass flow through the refrigeration system in cooling mode chilled and dried and then in the heating heat exchanger to the required air temperature in the so-called "reheat Operation "heated Use of the refrigerant flow through the heat exchanger for heating, the function of cooling and thus drying not executed at the same time become.
In der WO 03/053726 A1 sind verschiedene Ausführungsformen von Wärmepumpensystemen und entsprechende Verfahren zum Betreiben derselben beschrieben.In WO 03/053726 A1 are various embodiments of heat pump systems and corresponding method for operating the same described.
Es ist Aufgabe der vorliegenden Erfindung, ein Verfahren zum Betreiben einer Klimaanlage in einem Kraftfahrzeug zu schaffen, bei welchem im Heizmodus eine verbesserte Erwärmung des Fahrzeuginnenraums erreicht werden kann.It It is an object of the present invention to provide a method of operation to provide an air conditioning system in a motor vehicle, in which in heating mode, an improved heating of the vehicle interior can be achieved.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Das erfindungsgemäße Verfahren ermöglicht es, mit sehr geringem Aufwand die Klimaanlage in einem Kraftfahrzeug zu einer Wärmepumpe zu erweitern, wodurch sowohl im Stand als auch bei der Fahrt Wärme zur Beheizung des Fahrzeuginnenraums zur Verfügung gestellt werden kann. Eine derartige Wärmepumpe besitzt einen beispielsweise gegenüber einem PTC erheblich erhöhten Wirkungsgrad, wodurch das Bordnetz des Kraftfahrzeugs erheblich weniger belastet wird und es auch bei verbrauchsarmen Kraftfahrzeugen möglich ist, in sämtlichen Betriebszuständen eine ausreichende Erwärmung des Fahrzeuginnenraums zu erreichen.The inventive method allows it, with very little effort, the air conditioning in a motor vehicle to a heat pump to expand, thereby providing heat in both the state and while driving Heating of the vehicle interior can be provided. Such a heat pump has a considerably increased efficiency compared with a PTC, for example, whereby the electrical system of the motor vehicle significantly less burden and it is also possible for low-consumption motor vehicles, in all operating conditions sufficient heating of the vehicle interior.
Erfindungsgemäß wird das Kältemittel durch einen Gaskühler des Innenraumwärmetauschers geleitet, wodurch dieser ebenfalls zum Heizen genutzt und damit die Wärmeaustauschfläche wesentlich erhöht wird. Dabei kann durch die Verwendung des 3/2-Wegeventils die Anzahl der Schaltventile begrenzt und somit der Aufwand der Klimaanlage verringert werden.According to the invention refrigerant through a gas cooler of the indoor heat exchanger passed, whereby this also used for heating and thus the heat exchange surface essential elevated becomes. It can by using the 3/2-way valve, the number the switching valves limited and thus the cost of air conditioning be reduced.
Da die Wärmeaufnahme über die Umgebung stattfindet, wird der Kraftstoffverbrauch der Brennkraftmaschine während des Kaltstarts nicht erhöht und es ergeben sich Vorteile bezüglich des Verschleißes der Brennkraftmaschine.There the heat absorption over the Environment takes place, the fuel consumption of the internal combustion engine while the cold start does not increase and there are advantages regarding of wear the internal combustion engine.
Durch das erfindungsgemäße Verfahren wird die dem Innenraum zugeführte Luft getrocknet, so dass das Beschlagen der Scheiben des Kraftfahrzeugs verhindert werden kann.By the inventive method will be fed to the interior Air dried, allowing fogging of the windows of the motor vehicle can be prevented.
Um das Beschlagen von Scheiben noch wirkungsvoller zu verhindern, kann in einer vorteilhaften Ausgestaltung der Erfindung vorgesehen sein, dass bei einer Temperatur der Umgebungsluft von mehr als 5°C, vorzugsweise von mehr als 3°C, die dem Innenraum zugeführte Luft in dem Innenraumwärmetauscher getrocknet wird.Around The fogging of discs can be even more effective be provided in an advantageous embodiment of the invention, that at a temperature of the ambient air of more than 5 ° C, preferably of more than 3 ° C, the supplied to the interior Air in the interior heat exchanger is dried.
Wenn bei einer Temperatur der Umgebungsluft von weniger als 0°C, vorzugsweise von weniger als 3°C, die dem Innenraum zugeführte Luft in dem Innenraumwärmetauscher vorgeheizt wird, so ergibt sich eine Erhöhung der Heizleistung der Klimaanlage und damit eine verbesserte Erwärmung des Fahrzeuginnenraums.When at a temperature of the ambient air of less than 0 ° C, preferably less than 3 ° C, the air supplied to the interior in the Interior heat exchanger is preheated, this results in an increase in the heating power of the air conditioner and thus improved heating of the vehicle interior.
