Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the ambient heat is sufficient for the evaporation of the refrigerant.
  • the container 1 flows automatically into the container 1 via the piercing valve and the connecting line.
  • the activated carbon is provided therein, which adsorbs the inflowing refrigerant.
  • 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.
  • thermal energy can also be supplied to the refrigerant system by external heat sources.
  • 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.
  • 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.
  • 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 .
  • an adjustable flow restrictor 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.
