Definitions

  • the invention relates to a method and a device for disposing of a refrigerant system according to the preamble of claim 1 and of claim 3.
  • the refrigerant flowing in is then also cooled and the vapor pressure in the collecting container is kept low.
  • a disadvantage of this structure and the procedure to be carried out with it is that a cooling device for the collecting container is essential for satisfactory disposal. For this, dry ice or a compressed gas bottle with carbon dioxide as a coolant must be provided, these tools to the The location of the refrigerant system must be transported.
  • 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 is passed through an activated carbon mass provided in the collecting container without counterpressure, the collecting container being left open in the flow direction after the activated carbon mass.
  • the refrigerant emerging from the refrigerant system accumulates on the activated carbon mass or is adsorbed by the same.
  • the air previously in the collecting container can escape from the activated carbon mass and the collecting container into the free atmosphere.
  • the collecting container has a connecting piece for connection to the pipe system of the refrigerant system and an opening at a distance therefrom for connection to the environment.
  • the activated carbon mass is arranged in the collecting container between the connecting piece and the opening and fills the free cross section of the collecting container between the connecting piece and the opening.
  • a 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 at its free outer end a threaded piece or part of a screw coupling.
  • 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.
  • a piercing valve is connected to one of the connecting pieces 2 via a connecting hose and is tightly connected to a tube 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 ambient heat is sufficient for the evaporation of the refrigerant.
  • it flows automatically via the piercing valve and the connecting line into the container 1.
  • 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.
  • connection port facing away from the inflow side is left open during the disposal process, then the air, in particular in the container, can escape from the container, while the harmful fluorocarbons are sucked up by the same as through 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.
  • 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 allowed if several tanks are connected in series.
  • the active carbon mass is turned away on the flow side when open Connection spigot achieved a multiple specific capacity of the activated carbon mass compared to the disposal case with a closed outlet spigot.
