Abstract
Description
Die Erfindung betrifft einen Kältemitel-Kreislauf für eine Fahrzeug-Klimaanlage, bei dem der Kältemittelfluss durch einen Kompressor erzeugt wird.The The invention relates to a refrigeration cycle for one Vehicle air conditioning in which the flow of refrigerant through a Compressor is generated.
Eine Fahrzeugklimaanlage weist einen dem Kompressor nachgeschalteten Kältemittelkühler, der in Abhängigkeit vom eingesetzten Kältemittel als Gaskühler oder Kondensator fungiert, ein den Kältemittelfluss regelndes Expansionsorgan und einen mit diesem und der Eingangsseite des Kompressors verbundenen Verdampfer sowie diese Komponenten verbindende Kältemittelleitungen auf. Wenn der Kompressor abgeschaltet wird, kommt der Kältemittelfluss zum Erliegen, und es findet über eine Veränderung der Verteilung des Kältemittels im Kreislauf ein Druckausgleich statt. Bei erneutem Anschalten des Kompressors steht demzufolge kein oder nicht in ausreichendem Maße verdichtetes Kältemittel zur Verfügung, so dass es einige Zeit dauert, bis die Fahrzeug-Klimaanlage eine abgeforderte Kälteleistung erbringen kann. Um das Kältemittel nach dem Anschalten des Kompressors wieder zu verdichten und wieder Druck aufzubauen und eine abgeforderte Kälteleistung zur Verfügung zu stellen, wird Energie benötigt, was bei einem vom Fahrzeugmotor angetriebenen Kompressor mit einem Mehrverbrauch an Kraft verbunden ist. Zudem hat der Kompressor infolge des anfänglich noch ausgeglichenen Druckes im Kältemittelkreislauf ein schlechtes Drehmoment- und Anlaufverhalten, was als nachteilig angesehen wird.A Vehicle air conditioning has a compressor downstream Refrigerant cooler, which in dependence of the refrigerant used as a gas cooler or condenser, a refrigerant flow regulating expansion organ and one connected to this and the input side of the compressor Evaporator and these components connecting refrigerant pipes. If the compressor is switched off, the refrigerant flow comes to a halt, and it finds over a change the distribution of the refrigerant in the circulation pressure equalization instead. When you turn on the Compressor is therefore not or not sufficiently compacted refrigerant to disposal, so it takes some time for the vehicle air conditioning to take one requested cooling capacity can provide. To the refrigerant after turning on the compressor again to compress and again Pressure build up and a requested cooling capacity available put, energy is needed, what with a powered by the vehicle engine compressor with a More consumption of power is connected. In addition, the compressor has due of the initial still balanced pressure in the refrigerant circuit a poor torque and startup behavior, which is disadvantageous is seen.
Es ist Aufgabe der Erfindung, einen Kältemittelkreislauf für eine Fahrzeug-Klimaanlage nach dem Oberbegriff des Anspruchs 1 derart zu gestalten, dass das Anlaufverhalten des Kompressors und damit des Kältekreislaufs verbessert ist.It Object of the invention, a refrigerant circuit for a vehicle air conditioning According to the preamble of claim 1 to be designed such that the Start-up of the compressor and thus the refrigeration cycle is improved.
Diese Aufgabe wird bei einem Kältemittel-Kreislauf nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnendes Merkmal gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These Task becomes with a refrigerant cycle according to the preamble of claim 1 by the characterizing Feature solved. Advantageous embodiments are listed in the subclaims.
Die Erfindung besteht darin, dass die Verteilung der in einem Kältemittel-Kreislauf für eine Fahrzeug-Klimaanlage eingesetzten Kältemittelmenge während des Betriebes und des Nichtbetriebes gleich oder nahezu gleich ist und ein Druckausgleich im System nicht erfolgt, wobei der Kältemittel-Kreislauf einen Kompressor, einen mit dessen Ausgang verbundenen Kältemittelkühler, ein den Kältemittfluss regelndes Expansionsorgan und einen mit diesem und dem Eingang des Kompressors verbundenen Verdampfer und die genannten Komponenten verbindenen Kältemittelleitungen aufweist. Das bedeutet, dass die Verteilung des Kältemittels beim Abschalten des Kompressors, so wie diese im Betriebszustand der Klimaanlage gegeben ist, aufrecht erhalten bleibt. Damit entsprechen die Druckverhältnisse im Kältemittel-Kreislauf im Nichtbetriebszustand denen des Betriebszustandes, wobei die Umgebungstemperatur einen gewissen Einfluss auf die Drücke im System hat.The Invention is that the distribution of in a refrigerant circuit for one Vehicle air conditioning used refrigerant amount during the Operation and non-operation is equal or almost equal and a pressure equalization in the system does not take place, the refrigerant circuit a Compressor, a connected to the output of the refrigerant cooler, a regulating the flow of refrigerant Expansion organ and one with this and the input of the compressor Connected evaporator and the components mentioned connect Refrigerant lines having. That means the distribution of the refrigerant when switching off the compressor, as this in the operating state the air conditioner is given, is maintained. With that correspond the pressure conditions in the Refrigerant circulation in the non-operating state those of the operating condition, the ambient temperature has some influence on the pressures in the system.
Vorteilhaft ist dazu zwischen dem Kältemittelkühler und dem Expansionsorgan ein Absperrorgan angeordnet, das die Kältemittelleitung beim Abschalten des Kompressors sperrt und beim Anschalten freigibt. Das Absperrorgan verhindert einen Druckausgleich nach Abschalten des Kompressors.Advantageous is to between the refrigerant radiator and the expansion element arranged a shut-off, which the refrigerant line when switching off the compressor locks and releases when turning on. The shut-off prevents pressure equalization after switching off of the compressor.
Beim Einschalten der Fahrzeug-Klimaanlage steht sofort ausreichend verdichtetes Kältemittel zur Verfügung, wodurch das Anlaufverhalten des Kompressors bzw. dessen Drehmomentverhalten verbessert ist und die Energie eingespart wird, die erforderlich wäre, um den Kältemittel-Kreislauf in den vorbestimmten Betriebszustand mit den erforderlichen Druckverhältnissen zu versetzen. Die Klimaanlage spricht spontan an.At the Turning on the vehicle air conditioner is immediately sufficiently compacted refrigerant to disposal, whereby the start-up behavior of the compressor or its torque behavior is improved and the energy saved is needed would be to the refrigerant circuit in the predetermined operating condition with the required pressure ratios to move. The air conditioning is spontaneous.
Das Absperrorgan kann dabei ein elektrisches Ventil sein, das mit dem Kompressor über ein Steuergerät wirkverbunden ist und das beim Abschalten des Kompressors geschlossen und beim Anschalten desselben geöffnet wird.The Shut-off can be an electric valve that with the Compressor over a control unit is operatively connected and closed when switching off the compressor and when turned on the same opened becomes.
