Definitions

  • the invention relates to a fluid filling device according to the preamble of patent claim 1.
  • the fluids used for example, in refrigeration systems, such as air conditioning units, cooling devices, car air conditioning systems and the like, or in hydraulic systems, such as brake systems, cause environmental pollution, such as Damage to the ozone layer or groundwater if they are simply released into the atmosphere. It is therefore important that appropriate disposal is carried out when e.g. B. Refrigerant and oil can be removed from the refrigeration systems. For this purpose, it is regularly filled into transport containers, e.g. Bottles, necessary.
  • Refrigerant pumps are known, but with which only liquid refrigerant can be pumped.
  • suction devices for refrigerants are already known, with which the refrigerant can be sucked off before working on refrigeration systems.
  • These known suction devices have one Compressor open and a downstream condenser in which the hot gas leaving the compressor is subcooled and liquefied.
  • the filling operation with these suction devices is, however, relatively complicated.
  • These suction devices can only suck the refrigerant in gaseous form and the cooling oils can only be transported out to a limited extent. Furthermore, no automatic measures have been taken to prevent the transport containers from being overfilled.
  • the invention is therefore based on the object of improving a fluid filling device according to the preamble of patent claim 1 in such a way that the filling process is simplified with a simple and inexpensive construction.
  • This is achieved according to the invention by the features characterizing claim 1.
  • the solution according to the invention includes that the suction part is not in the cycle. As a result, the oil in the compressor does not have to be changed after each expiration and mixing problems are avoided.
  • the solution according to the invention can be used universally, i.e. independent of the type of refrigerant, but also independent of the fluid in the system to be disposed of. It is thus with the device according to the invention e.g. a brake system can also be disposed of.
  • An advantageous embodiment of this solution provides a bypass line which branches off in front of the condenser and is recombined with the line behind the liquid pump. Via this bypass line, the first part of the fluid mixture is advantageously transferred directly to the container at the beginning of the filling process.
  • Another solution according to the invention is characterized by the features characterizing claim 4.
  • a liquid separator which is followed by a liquid pump, is arranged in the line connecting the connections.
  • a compressor and a condenser are provided in a second line starting from the liquid separator. Both lines are brought together again before the second connection.
  • This system is particularly suitable for simultaneously extracting refrigerant gas, refrigerant liquid and oil, for example.
  • An advantageous embodiment of the invention provides that a bypass line is provided which branches off the line in front of the liquid separator and is brought back together with the line behind the liquid pump.
  • a particularly energy-saving embodiment of the invention is characterized in that a level switch is connected to the liquid separator, by means of which the liquid pump can be switched.
  • the lubricant circuit of the compressor can be connected to the liquid pump.
  • An economical embodiment of the invention provides that the line is led through the liquid separator in a region between the compressor and the condenser.
  • a gear pump is used as the liquid pump, as is provided according to another advantageous embodiment of the invention.
  • a pump with a bypass in the manner of an oil burner pump is preferably used.
  • a weighing device is advantageously provided.
  • This weighing device is connected in a suitable manner to the drives of the individual units and switches them, e.g. via end contacts, when the maximum filling quantity is reached. An overfilling of the transport container is therefore excluded.
  • Embodiments of the invention are shown in the drawing and described below using the example of a filling device for refrigerant-oil mixture.
  • FIG. 1 is a schematic representation of a first embodiment of the invention * -
  • FIG. 2 shows a schematic representation of a second embodiment of the invention ?
  • Fig. 3 is a schematic representation of a third embodiment of the invention.
  • FIG. 1 shows a first embodiment of a refrigerant-oil mixture filling device 2.
  • the refrigerant-oil mixture filling device 2 has a first line 4, at one end of which a first connection 6 is provided, for connecting the device to a (not shown) refrigeration system or container which contains the refrigerant to be filled and at the other end second connection 8 is provided for connecting filling containers 10 which receive the filled fluid.
  • a shut-off valve 12 is connected downstream of the first connection 6 and a shut-off valve 14 is connected upstream of the second connection 8.
  • a condenser 18 is arranged in the first line 4 between these valves.
  • the mixture to be extracted is condensed and supercooled in this condenser 18, for which purpose a fully hermetically closed refrigerant circuit is connected, which contains a compressor 20 and a condenser 22.
  • the liquefier 18 is followed by a liquid pump 16 which pumps out the supercooled mixture and supplies it to the container 10.
  • a bypass line 24 branches off from the line 4 and is connected again to the first line 4 before the valve 14.
  • Check valves 26, 28 and shut-off valves 30, 32 downstream thereof are provided both in line 4 and in the bypass line 24. The check valves prevent the mixture from flowing back, so that the clearly defined flows cannot be reversed.
  • a branch line 34 extends from the common line section 4a and has a connection 36 for a vacuum pump.
  • the vacuum pump serves to make the system operational by removing any liquid that may be present.
  • a negative pressure monitor is connected to the common line section 4b and initiates a switch-off process when a certain pressure is reached, ie when no more mixture flows in.
  • An overpressure monitor 39 prevents the container pressure from rising above a critical value.
  • an automatic weighing device 40 which all drives (liquid pump, compressor,
  • Condenser fan switches off automatically when the maximum charge is reached.

  • a second line 74 opens into the liquid separator, in which a compressor 70 and a condenser 72 are arranged.
  • a check valve 78 and a shut-off valve 82 are again provided in this line.
  • a branch line 84 with a vacuum connection 86 extends from the line section 54a.
