Definitions
- the device for carrying out the method according to the invention can be designed as a mobile device with a memory for the cryogenic coolant.
- An electric drive is not required, use in explosion-proof areas is possible.
- With a single cooling device several collecting containers can be cooled one after the other. The transfer times are short. With large quantities of refrigerant, a gradual withdrawal is also possible.
- the method according to the invention is not limited to the disposal of refrigeration and air conditioning systems, but can be used wherever media with appropriate physical data are to be collected safely and without loss, e.g. Aerosols from the supply systems of nuclear power plants.
- the pressure of the refrigerant in the system acts on the collecting container 1.
- the refrigerant only flows into the collecting container 1 when the cooling sleeve 3 is pressurized with CO2 dry ice.
- the cooling of the collecting container 1 by the cooling sleeve 3 causes a negative pressure in the collecting container 1, through which the entire liquid refrigerant is sucked out of the system.
- the remaining gaseous refrigerant also condenses except for a slight residue in the collecting container 1, which acts like a cryopump.
- the shut-off valve 8 is closed and the collecting container 1 is separated from the connecting line 7. The system can now be serviced or repaired.
