Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Entsorgen einer mit einem verdampfbaren Kältemittel beschickten, geschlossenen Kältemittelsystems, insbesondere von Haushaltskühl- oder Gefriergeräten bzw. Wärmepumpenanlagen.The invention relates to a method and a device for disposing of a closed refrigerant system charged with an evaporable refrigerant, in particular household refrigerators or freezers or heat pump systems.

Zur Entsorgung von Kältemittelsystemen ist es bekannt (DE-GM 87 08 522), mittels eines Motorkompressors das Kältemittel aus einem Kältmittelkreislauf über eine Rohrleitung abzusaugen und das verdichtete Kältemittel über einen Kondensator zu führen, aus dem flüssiges Kältemittel in eine Entsorgungsflasche gedrückt wird. Um die ordnungsgemäße Funktion dieses Aggregates sicherzustellen, muß dabei noch ein Ölabscheider vorgesehen sein, über welchen das vom Kompressor gefördete Öl zurück zum Kompressor gefördert wird. Außerdem ist ein Sicherheitsschalter erforderlich, der bei auftretendem Unter- und/oder Überdruck den Motorkompressor abschaltet. Dieses Aggregat stellt ein Arbeitsmittel mit hohem Eigengewicht dar, das aufgrund seines Gewichtes Handhabungsschwierigkeiten beim Transport zum zu entsorgenden Kältemittelsystem mit sich bringt. Ferner zeigt es sich im praktischen Betrieb, daß für das Entsorgen üblicher Kältemittelkreisläufe ein hoher Zeitaufwand von 15 bis 20 Minuten für das Absaugen des Kältemittels erforderlich ist, was die Arbeitszeit und damit die Kosten eines Kundendiensteinsatzes erhöht. Außerdem muß am Entsorgungsort ein elektrischer Netzanschluß für den Betrieb des Motorkompressors vorhanden sein.For the disposal of refrigerant systems, it is known (DE-GM 87 08 522) to suck off the refrigerant from a refrigerant circuit via a pipeline by means of a motor compressor and to guide the compressed refrigerant over a condenser from which liquid refrigerant is pressed into a disposal bottle. In order to ensure the proper functioning of this unit, an oil separator must also be provided, via which the oil delivered by the compressor is conveyed back to the compressor. In addition, a safety switch is required, which switches off the motor compressor when negative and / or positive pressure occurs. This unit is a work tool with a high weight, which due to its weight causes handling difficulties during transport to the refrigerant system to be disposed of. Furthermore, it has been shown in practical operation that the disposal of conventional refrigerant circuits requires a high expenditure of time of 15 to 20 minutes for the suction of the refrigerant, which increases the working time and thus the cost of a service call. In addition, an electrical mains connection for the operation of the motor compressor must be available at the disposal site.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Entsorgen eines Kältemittelsystems anzugeben, die bei einfacher Handhabung einen geringen apparativen Aufwand erfordern.The invention is based on the object of specifying a method and a device for disposing of a refrigerant system which, with simple handling, require little outlay on equipment.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung dadurch, daß das Kältemittelsystem bei einer Temperatur, die höher als der Siedepunkt des Kältemittels liegt, geöffnet und das Kältemittel in einen mit Aktivkohle versehenen Auffangbehälter geleitet wird. Dazu kann eine Behälter wenigstens teilweise mit Aktivkohle gefüllter mit einem Anstechventil versehen sein, das an das Rohrsystem des Kältemittelsystems anschließbar ist.This object is achieved according to the invention in that the refrigerant system is opened at a temperature which is higher than the boiling point of the refrigerant and the refrigerant is passed into a collecting container provided with activated carbon. For this purpose, a container can be at least partially filled with activated carbon and provided with a piercing valve which can be connected to the pipe system of the refrigerant system.

Bei einer Verfahrensweise gemäß der Erfindung wird die Tatsache ausgenutzt, daß übliche Kältmittel wie R12 bereits bei Raumtemperatur sieden. Im Kältemittelsystem herrscht dadurch ein Überdruck, der das Kältemittel selbsttätig aus dem Kreislauf herausdrückt. Es strömt dann über entsprechende Rohrleitungen in den dafür vorgesehenen Behälter ein. Hierzu braucht lediglich der Behälter mit einem Anstechventil verbunden zu werden, das an das Rohrsystem des Kältemittelssystems angelegt wird und das Rohrsystem an dieser Stelle perforiert. Um das Volumen des Behälters klein halten zu können, ist darin eine Aktivkohlemasse vorgesehen, welche das Kältemittel adsorbiert. Im praktischen Betrieb hat es sich dabei gezeigt, daß übliche Kältemittelkreisläufe in Haushaltskühl- oder Gefriergeräten, die beispielsweise eine Kältemittelfüllung von 120 Gramm R12 aufweisen, mit einer Filterpatrone mit rundem Querschnitt und Aktivkohlefüllung entsorgt werden können, wobei die Filterpatrone eine Länge von 570 mm und einem Außendurchmesser von 40 mm aufweist, wobei sich die Aktivkohlefüllung über der Länge und den lichten Innenquerschnitt erstreckt. Eine Filterpatrone in dieser Ausführung ist einfach im Aufbau und leicht handhabbar. Der erforderliche Zeitraum für eine hinreichende Entleerung des Kältemittelsystems beträgt dabei ca. 10 Minuten.A procedure according to the invention takes advantage of the fact that conventional refrigerants such as R12 boil at room temperature. This creates an overpressure in the refrigerant system, which automatically pushes the refrigerant out of the circuit. It then flows into the container provided for this via corresponding pipelines. For this purpose, only the container needs to be connected to a piercing valve which is applied to the pipe system of the refrigerant system and perforates the pipe system at this point. In order to keep the volume of the container small, an activated carbon mass is provided therein, which adsorbs the refrigerant. In practical operation, it has been shown that conventional refrigerant circuits in household refrigerators or freezers, which have a refrigerant charge of 120 grams R12, for example, can be disposed of with a filter cartridge with a round cross-section and activated carbon charge, the filter cartridge being 570 mm long and one Has an outer diameter of 40 mm, the activated carbon filling extending over the length and the clear inner cross section. A filter cartridge in this version is simple in construction and easy to handle. The time required for the refrigerant system to drain sufficiently is approximately 10 minutes.

Andere vorteilhafte Weiterbildungen sind in den übrigen Ansprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels näher erläutert.Other advantageous developments are explained in more detail in the remaining claims and the following description of an embodiment.

Ein Bahälter 1 in Form einer langgestreckten Filterpatrone mit rundem Querschnitt weist an axial gegenüberliegenden Enden je einen Anschlußstutzen 2 auf, der an seinem freien äußeren Ende ein Gewindestück bzw. einen Teil einer Schraubkupplung trägt. Jedes Anschlußstück kann zusätzlich mit einer Verschlußkappe oder einem Absperrventil (Schraderventil) ausgestattet sein, mit welchen der Hohlraum des Behälters dicht verschließbar ist, wenn Kältemittel adsorbiert wurde. Innerhalb des Behälters befinden sich benachbart zu den Anschlußstutzen 2 Feinsiebe 3, welche über den inneren Querschnitt des Behälters 1 reichen und zwischen welchen der Hohlraum des Behälters voll mit einer Aktivkohlemasse 4, insbesondere in Form von Granulat, gefüllt ist. An einen der Anschlußstutzen 2 ist über einen Verbindungsschlauch ein Anstechventil angeschlossen, das an ein Rohr des Kältemittelsystems dicht angelegt wird. Anschließend wird mittels des Anstechventils das Rohr perforiert.A rail container 1 in the form of an elongated filter cartridge with a round cross section has at each axially opposite ends a connecting piece 2 which carries a threaded piece or part of a screw coupling at its free outer end. Each connection piece can additionally be equipped with a closure cap or a shut-off valve (Schrader valve), with which the cavity of the container can be sealed when refrigerant has been adsorbed. Within the container are adjacent to the connecting piece 2 fine sieves 3, which extend over the inner cross section of the container 1 and between which the cavity of the container is fully filled with an activated carbon mass 4, in particular in the form of granules. At one of the connecting pieces 2, a piercing valve is connected via a connecting hose, which is tightly applied to a pipe of the refrigerant system. The pipe is then perforated using the piercing valve.

Nachdem diese Vorrichtung insbesondere für die Entsorgung von Haushalts-Kältemittelkreisläufen vorgesehen ist und das entsprechende Gerät bei Raumtemperatur aufgestellt ist, reicht die Umgebungswärme für das Verdampfen des Kältemittels. Es strömt dadurch selbsttätig über das Anstechventil und die Vrbindungsleitung in den Behälter 1. Um das Volumen des Behälters 1 kleinhalten zu können, ist darin die Aktivkohle vorgesehen, welche das zuströmende Kältemittel adsorbiert. Es kann dadurch in dem von der Aktivkohlemasse eingenommenen Raum eine wesentlich höhere Kältemitteldampfmenge angelagert werden, als dem Raumvolumen entspricht. Sind größere Kältemittelmengen zu entsorgen, dann können mehrere der Behälter parallel oder in Serie zueinander geschaltet werden.After this device is intended in particular for the disposal of household refrigerant circuits and the corresponding device is set up at room temperature, the ambient heat is sufficient for the evaporation of the refrigerant. As a result, it flows automatically into the container 1 via the piercing valve and the connecting line. In order to keep the volume of the container 1 small, the activated carbon is provided therein, which adsorbs the inflowing refrigerant. As a result, a significantly higher quantity of refrigerant vapor can be deposited in the space occupied by the activated carbon mass than corresponds to the volume of the space. If larger quantities of refrigerant have to be disposed of, several of the tanks can be connected in parallel or in series with each other.

Ist die Umgebungstemperatur des zu entsorgenden Kältemittelkreislaufs niedriger als die Siedetemperatur des Kältemittels, dann kann dem Kältemittelsystem durch äußere Wärmequellen auch Wärmeenergie zugeführt werden. Daneben ist es auch möglich, den Behälter 1 zu kühlen, insbesondere mittels Trockeneis oder einer Kältespeichermasse, die den Mantel des Behälters 1 umgibt und mit einer Wärmeisolierschicht nach außen hin abgedeckt ist. Durch Evakuieren oder Erwärmen kann im übrigen das an die Aktivkohlemasse 4 angelagerte Kältemittel nach dem Trennen vom Kältemittelsystem aus dem Behälter 1 entfernt werden.If the ambient temperature of the refrigerant circuit to be disposed of is lower than the boiling temperature of the refrigerant, then thermal energy can also be supplied to the refrigerant system by external heat sources. In addition, it is also possible to cool the container 1, in particular by means of dry ice or a cold storage mass, which surrounds the jacket of the container 1 and is covered with a heat insulation layer to the outside. By evacuation or heating, moreover, the refrigerant attached to the activated carbon mass 4 can be removed from the container 1 after separation from the refrigerant system.

Bei der Anwendung des mit Aktivkohle versehenen Behälters kann der Anschlußstutzen 2, der der Zuströmseite abgewandt ist, verschlossen werden. Das ist dann zweckmäßig, wenn eine im Verhältnis zum maximalen Aufnahmevermögen der Aktivkohlemasse relativ geringe Kältemittelmenge entsorgt werden soll. Es baut sich dann nämlich im Behälter ein gewisser Gegendruck auf, der das Zuströmen von weiterem Kältemittel unterbinden kann. Dem kann zwar durch Anwärmen des Kältemittelkreislaufes oder durch Kühlen des Behälters entgegengewirkt werden, jedoch läßt sich das maximale Aufnahmevolumen der Aktivkohlemasse in dieser Betriebsweise nicht ausnutzen.When using the container provided with activated carbon, the connecting piece 2, which faces away from the inflow side, can be closed. This is useful if a relatively small amount of refrigerant is to be disposed of in relation to the maximum absorption capacity of the activated carbon mass. A certain counter pressure then builds up in the container, which can prevent the flow of further refrigerant. This can be counteracted by warming up the refrigerant circuit or by cooling the container, but the maximum absorption volume of the activated carbon mass cannot be used in this mode of operation.

Wird dagegen der der Zuströmseite abgewandte Anschlußstutzen während des Entsorgungsvorganges offengelassen, dann kann die insbesondere im Behälter vorhandene Luft aus dem Behälter entweichen, während die schädlichen Fluorkohlenwasserstoffe beim Durchströmen der Aktivkohlemasse von derselben wie von einem Schwamm aufgesaugt werden. Eine Unterkühlung des patronenförmigen Behälters ist dabei nicht erforderlich. Es ist nur darauf zu achten, daß die im Kältemittelkreislauf enthaltene Kältemittelmenge nicht das Adsorbtionsvermögen der Aktivkohlemasse übersteigt. Bei größeren zu entsorgenden Kältemittelmengen können daher mehrere Behälter an den Kältemittelkreislauf angeschlossen werden, wobei die Reihenschaltung der Behälter besonders vorteilhaft ist, weil dann zunächst der erste Behälter soviel Kältemittel aufnimmt, wie seinem Adsorbtionsvermögen entspricht und erst danach aufeinanderfolgend der oder die weiteren Behälter mit Kältemittel beaufschlagt werden. Um dabei ein zu schnelles, das zeitliche Adsorbtionsvermögen der Aktivkohlemasse überschreitendes Durchströmen von Kältemittel zu verhindern, wird in den Zuströmweg zum Behälter 1 eine Strömungsdrossel eingeschaltet, die durch entsprechende Bemessung des Querschnitts der Zuströmleitung oder durch eine darin eingefügte Strömungsblende bzw. ein einstellbares Drosselventil ausgebildet ist. Bei Anwendung, einer einstellbaren Strömungsdrossel kann ein größerer Strömungsquerschnitt zugelassen werden, wenn mehrere Behälter in Reihe angeschlossen sind. Im übrigen wird von der Aktivkohlemasse bei offenem strömungsseitig abgewandten Anschlußstutzen eine mehrfache spezifische Aufnahmefähigkeit der Aktivkohlemasse gegenüber dem Entsorgungsfall mit geschlossenem ausgangsseitigen Anschlußstutzen erreicht.If, on the other hand, the connecting piece facing away from the inflow side is left open during the disposal process, the air, in particular in the container, can escape from the container, while the harmful fluorocarbons are sucked up by the same as a sponge when flowing through the activated carbon mass. It is not necessary to overcool the cartridge-shaped container. It is only important to ensure that the amount of refrigerant in the refrigerant circuit does not exceed the adsorbing capacity of the activated carbon mass. With larger quantities of refrigerant to be disposed of, several containers can therefore be connected to the refrigerant circuit, the series connection of the containers being particularly advantageous because the first container then absorbs as much refrigerant as its adsorptive capacity and only then consecutively applies refrigerant to the other container or containers will. In order to prevent a too rapid flow of refrigerant that exceeds the adsorbing capacity of the activated carbon mass, a flow restrictor is switched into the inflow path to the container 1, which is designed by appropriate dimensioning of the cross section of the inflow line or by a flow orifice or an adjustable throttle valve inserted therein . When using an adjustable flow restrictor, a larger flow cross section can be permitted if several vessels are connected in series. Otherwise, the active carbon mass is turned away on the flow side when the mass is open Connection spigot achieved a multiple specific capacity of the activated carbon mass compared to the disposal case with a closed outlet spigot.
