TECHNISCHES GEBIETTECHNICAL TERRITORY
Die Erfindung betrifft ein Service-Gerät für Fahrzeugklimaanlagen gemäß dem Oberbegriffs von Anspruch 1.The The invention relates to a service device for vehicle air conditioning systems according to the preamble of claim 1.
TECHNISCHER HINTERGRUNDTECHNICAL BACKGROUND
Service-Geräte für Fahrzeugklimaanlagen dienen unter anderem dazu, den Kältemittelkreislauf von Fahrzeugklimaanlagen von Zeit zu Zeit zu entleeren und eine neue Kältemittelfüllung einzubringen. Dabei ist es erforderlich genaue Mengen und Kältemittelspezifikationen einzuhalten. Außerdem muss in vielen Fällen Schmieröl für den Kompressor des Kältemittelkreislaufs der Fahrzeugklimaanlage entfernt und wieder nachgefüllt werden. Auch dies erfolgt in vom Fahrzeugtyp bzw. Klimagerätetyp abhängigen Mengen und Spezifikationen. Manche Fahrzeugklimaanlagen benötigen außerdem ein Additiv für den Kältemittelkreislauf, welches bei einem Wartungsservice aufgefüllt wird. Üblicherweise gelangt das Kompressorenöl in den Kältemittelkreislauf und wird beim Betrieb der Fahrzeugklimaanlagen daher mit umgepumpt. Nur ganz bestimmte Paarungen von Kältemittel und Kompressorenöl sind für diesen Zweck miteinander verträglich. Um nach dem Absaugen des Kältemittel/Kompressorenölgemisches zumindest einen Teil des Kältemittels zur Wiedervenendung zurückgewinnen zu können, weisen Service-Geräte für Fahrzeugklimaanlagen üblicherweise auch einen Separator auf, mit welchem Kältemittel aus dem Kältemittel/Kompressorenölgemisch zur Wiederverwendung abgetrennt werden kann. Gebrauchtes Kompressorenöl sowie, gegebenenfalls, gebrauchtes Additiv wird/werden in der Regel durch das Service-Gerät aufgefangen, um später verworfen zu werden.Serve service equipment for vehicle air conditioning Among other things, the refrigerant circuit of From time to time to empty vehicle air conditioners and a new one To introduce refrigerant charge. there It is necessary to comply with exact quantities and refrigerant specifications. Furthermore must in many cases oil for the Compressor of the refrigerant circuit the vehicle air conditioner removed and refilled. This also takes place in dependent on the vehicle type or air conditioner type quantities and specifications. Some vehicle air conditioners also require a Additive for the refrigerant circuit, which is filled up at a maintenance service. Usually, the compressor oil gets into the Refrigerant circulation and is therefore pumped during operation of the vehicle air conditioning with. Only very specific pairings of refrigerant and compressor oil are for this Purpose compatible with each other. To after the suction of the refrigerant / compressor oil mixture at least part of the refrigerant to recover for re-transmission to be able to have service equipment for vehicle air conditioning usually also a separator, with which refrigerant from the refrigerant / compressor oil mixture can be separated for reuse. Used compressor oil and, if necessary, used additive is / are usually passed through the service device intercepted later to be rejected.
Der Vorratsbehälter für Kältemittel muss einem gewissen Innendruck Stand halten und ist daher als Druckbehälter ausgebildet. Der Kältemittel-Füllstand ändert sich aufgrund der Rückführung von aus der Fahrzeugklimaanlage abgesaugtem und separiertem Kältemittel und der Wiederbefüllung der Fahrzeugklimaanlage laufend. Bei der Wiederbefüllung der Fahrzeugklimaanlage mit Kältemittel müssen von Fahrzeug zu Fahrzeug unterschiedliche Kältemittelmengen abgegeben werden. Die Mengendosierung erfolgt über die Gewichtsbestimmung des abgegebenen Kältemittels anhand von Wägeergebnissen des gesamten Vorratsbehälters. Aufgrund strenger werdender gesetzlicher Bestimmungen über den Nachweis des Verbleibs der Kältemittel, werden in Zukunft strengere Anforderungen an die Wägegenauigkeit erwartet, was unter anderem beinhaltet, dass Nullpunktkontrollen und Nullpunktnachstellungen von Zeit zu Zeit durchgeführt werden müssen. Wegen der Transportierbarkeit der Service-Geräte für Fahrzeugklimaanlagen innerhalb einer Werkstatt bzw. beim Außeneinsatz der Service-Geräte über größere Transportstrecken besteht zudem die Gefahr von Nullpunktverstellungen aufgrund von Erschütterungen des Service-Gerätes. Für derartig hohe Anforderungen sind die auf dem Markt befindlichen Service-Geräte nicht ausgelegt.Of the reservoir for refrigerants must withstand a certain internal pressure and is therefore designed as a pressure vessel. The refrigerant level changes due to the repatriation of from the vehicle air conditioning aspirated and separated refrigerant and refilling the vehicle air conditioning system in progress. When refilling the Vehicle air conditioning with refrigerant have to different amounts of refrigerant are emitted from vehicle to vehicle. The metering is done via the determination of the weight of the discharged refrigerant based on weighing results of the entire reservoir. Due to stricter legal provisions on the Proof of the fate of the refrigerants, In future, stricter requirements for weighing accuracy are expected, which includes, among other things, zero checks and zero adjustments done from time to time Need to become. Because of the portability of the service equipment for vehicle air conditioners within a workshop or outdoor use the service devices over longer transport distances There is also the risk of zero adjustments due to shocks of the service device. For such high demands are not on the market service devices designed.
DIE ERFINDUNGTHE INVENTION
Durch die Erfindung soll das Problem gelöst werden, exaktere Wägungen des Vorratsbehälters für Kältemittel zu ermöglichen. Zur Lösung dieser Aufgabe wird ein Service- Gerät mit den Merkmalen des Anspruchs 1 vorgeschlagen. Durch die erfindungsgemäße Entlastungseinrichtung wird die Wägeeinrichtung von dem Vorratsbehälter bei Nichtabgabe von Kältemitteln mechanisch entlastet. Diese Entlastung kann grundsätzlich automatisch erfolgen. Dies ist aber nicht unbedingt erforderlich, z.B. wenn das Servicegerät zwischen zwei Wartungseinsätzen nicht bewegt oder anderweitig erschüttert wird. Es reicht daher in der Regel aus, wenn die Entlastungseinrichtung durch das Wartungspersonal bei Bedarf betätigt wird. Hierzu kann ein einfacher Hebelmechanismus oder eine Schraubspindel oder ein anderer Hub- oder Kippmechanismus dienen, mittels dessen der Vorratsbehälter von dem/den Auflagepunkten an der Wägeeinrichtung angehoben wird. Wenn der Vorratsbehälter nur einseitig auf der Wägeeinrichtung aufliegt und an seiner anderen Seite im Service-Gerät gelagert ist, reicht ein Verkippen um den geräteseitigen Auflagepunkt aus. Die Wägeeinrichtung kann im entlasteten Zustand, insbesondere automatisch, einen Nullpunktabgleich durchführen. Beim Wiederbelasten der Wägeeinrichtung und nachfolgender Kältemittelabgabe reicht die Bestimmung des Differenzgewichtes zwischen dem Anfangsgewicht und dem Endgewicht des Vorratsbehälters für eine exakte Bestimmung der Kältemittelabgabe aus.By the invention aims to solve the problem, more accurate weighing the Reservoir for refrigerant to enable. To the solution This task becomes a service device with the Characteristics of claim 1 proposed. By the discharge device according to the invention becomes the weighing device from the reservoir for non-delivery of refrigerants mechanically relieved. This discharge can basically be automatic respectively. However, this is not absolutely necessary, e.g. if that service equipment not between two maintenance operations moved or otherwise shaken becomes. It is therefore usually sufficient if the discharge device is operated by the maintenance personnel if necessary. This can be a simple lever mechanism or a screw spindle or other lifting or tilting mechanism serve, by means of which the reservoir of the support points on the weighing device is raised. If the reservoir is only one-sided on the Weighing device rests and is stored on the other side in the service device, is sufficient Tilting around the device side Outpoint. The weighing device can in the unloaded state, in particular automatically, a zero point adjustment carry out. When reloading the weighing device and subsequent release of refrigerant ranges the determination of the difference weight between the initial weight and the final weight of the reservoir for an exact Determination of the refrigerant release out.
