Definitions

  • the invention relates to an air conditioning compressor for air conditioning systems, in particular for motor vehicles, or an air conditioner with an air compressor, wherein the air compressor is connected to a high pressure area and a suction pressure, possibly from the engine room of the air compressor compressor drive pressure return from the engine pressure range in the suction pressure and a filter , in particular a dirt particle filter, is arranged in the suction pressure region and in addition a dirt particle separator is arranged in the suction pressure region.
  • compressors having a drive-chamber pressure return have the disadvantage that the drive-chamber pressure within the compressor is led back directly into the suction region and dirt particles, such as, for example, abrasion from the drive chamber due to the mechanical load of the engine, are returned to the suction region of the air-conditioning compressor. There, the dirt particles can cause damage, for example in the region of the piston and cylinder liners or valve devices.
  • an air conditioning compressor for air conditioners especially for motor vehicles, or an air conditioner with an air compressor
  • the air compressor is connected to a high pressure area and with a suction pressure, possibly from the engine room of the air conditioning compressor a Triebraumdruckschreib Installation from the engine pressure range in the suction pressure occurs and a filter, in particular a dirt particle filter, is arranged in the suction pressure region and in which or which of the dirt particle separators is designed as a cyclone separator, wherein by centrifugal force the dirt particles deposited on the walls of the Schmutzpietyabscheiders and collected in a debris collecting device while the purified refrigerant flow is passed into the suction of the air conditioning compressor.
  • an air conditioning compressor or an air conditioner in which or which of the dirt particle is arranged upstream of the filter in the flow direction.
  • an air conditioning compressor or an air conditioning system is preferred in which or which of the dirt particle is arranged in the compressor housing.
  • an air conditioning compressor or air conditioning system in which or at which the engine pressure return between the filter and the compressor input is connected.
  • an air-conditioning compressor or an air-conditioning system in which or between which the filter and the dirt particle separator the drive-chamber pressure return is connected so that the drive-chamber pressure return is also filtered.
  • Another air-conditioning compressor or an air-conditioning system is preferred in which or which the drive-pressure return in the flow direction is connected upstream of the dirt-particle separator, so that the driving-pressure return of dirt particles in the dirt-particle separator is also cleaned.
  • An inventive compressor or an air conditioner according to the invention is characterized in that the Schmutzpumbleabscheider outside the compressor housing and the filter are arranged within the compressor housing and the drive chamber pressure return in the flow direction behind the filter between the filter and Kompressoransaug Colour is attached.
  • Another inventive air conditioning compressor or an air conditioning system is characterized in that the Schmutzpumbleabscheider and the filter are arranged outside of the compressor housing and the drive chamber pressure feedback is fed back in the flow direction behind the filter in the intake of the compressor. Also preferred is an air conditioning compressor or air conditioner, in which or which of the dirt particle separators outside the housing and the filter are arranged inside the housing and the drive chamber pressure return is connected upstream of the filter in the flow direction, so that the drive chamber pressure feedback is filtered.
  • FIG. 1 schematically an air compressor 1, a dirt particle filter 3 and a Schmutzpumbleabscheider 5 is shown. These three elements are located within the air conditioning compressor housing, which is shown by the dashed line 7.
  • the Schmutzpumbleabscheider 5 works on the cyclone principle, being deposited by centrifugal force on the walls of the separator 5, the dirt particles and collected in a dirt particle collecting device 9.
  • Such drive pressure return pressures are known in the adjustable compressors and will not be explained further here.
  • the wiring diagram in FIG. 2 differs from the schematic in FIG. 1 in that another drive-chamber pressure return 25 is now connected in a suction-pressure-range line section 27 between the filter 3 and the dirt-particle separator 5.
  • dirt particles from the drive-chamber pressure guide 25 now pass through the filter 3 in any case, while the main suction flow from the region 21 additionally passes the dirt-particle separator 5. Dirt particles that originated within the drive room are so caught in any case by the filter 3 and not directly to the intake 15 of the air compressor 1, as in FIG. 1 shown, fed.
  • the wiring diagram in FIG. 3 differs from the schematics in FIGS. 1 and 2 in that another drive-chamber pressure return 29 is now connected to a line section 31 in the suction region 21, so that the drive-chamber pressure return 29 also has to pass through the dirt-particle separator 5 and thus the subsequently switched filter 3 no longer has to absorb these dirt particles, resulting in an even lower pressure drop and an even better efficiency of the system during the operating time leads.
  • the Schmutzp firmwareabscheider 5 is arranged outside of the air conditioning compressor housing 7 in a line section 33 of the air conditioner.
  • the Schmutzp firmwareabscheider 5 can therefore be arranged at a separate location plant so that it is easily accessible regardless of the installation of the air conditioning compressor and thus the sump 9 can be maintained accordingly.
  • the drive-pressure return 17 takes place here again within the compressor housing 7 in the connection 13 and thus in the intake 15 of the compressor 1, as already in FIG. 1 shown.
  • FIG. 6 again, only the dirt particle 5 is disposed outside of the compressor housing 7. Since the filter 3 is again arranged inside the compressor housing 7, in turn the drive chamber pressure guide 25, as already in FIG. 2 shown, made in the connection 27 and thus pass through the filter 3, so that dirt particles can be trapped from the drive room in the filter 3.
  • the principle of the invention is therefore the introduction of an additional Schmutzp firmwareabscheiders 5 for the separation of particles, which are collected in a collecting space 9 and therefore can not reach the downstream filter 3. As a result, no substantially noticeable filter cake will build up in the filter 3, which would otherwise produce an increasing pressure drop over the course of the operating time, which would be detrimental to the efficiency of the system.
  • Another object of the invention is a connection of the Abtriebraumabstroms 25 and 29 to the suction region 15 of the compressor 1 in such a manner that the compressor control characteristic is not affected inadvertently, for example, by the increasing pressure drop across the filter 3. This can in particular by returning the engine room exhaust over the compound 29 in FIG. 3 take place before the Schmutzpietyabscheider 5. These tasks can not be achieved, for example, by dirt separators and strainers on the outlet side of the machine.
