Definitions

  • refrigerant collecting tanks In refrigeration systems, such as those used in motor vehicles, so-called refrigerant collecting tanks are used, in which liquefied refrigerant can be collected, so that in the refrigerant tank cold can be stored.
  • the capacity of the refrigerant receiver is substantially determined by the volume of the refrigerant receiver minus the elements disposed in the refrigerant receiver.
  • a maximum level of the refrigerant collecting container is determined in particular additionally by a gas filter located in the refrigerant collecting container. This filter gaseous refrigerant before exiting the refrigerant receiver. However, when the level of the liquid refrigerant in the refrigerant receiver reaches the gas filter, the liquid refrigerant may wet the filter surface, whereby an increased amount of liquid refrigerant is discharged from the refrigerant receiver.
  • the gas filter has a substantially cylindrical shape.
  • Such a cylindrically shaped gas filter is special easy to make.
  • the application of filter material to a skeleton of the gas filter is facilitated.
  • a favorable variant provides that the support region is annular. Thereby, a particularly easy to manufacture and stable construction of the gas filter can be achieved.
  • the support area thus adapts favorably to the shape of the liquid separator.
  • the gas filter has at least two struts, preferably at least four struts, which connect the support section to the ground.
  • the recesses are formed between the struts, which are covered with filter material.
  • the outer wall of the gas filter is formed at least by the struts and the filter material.
  • an outer diameter of the support section corresponds to an inner diameter of the liquid separator, so that the gas filter can be inserted into the liquid separator. It is understood that the outer diameter of the support portion must be at least minimally smaller than the inner diameter of the liquid separator, so that the gas filter can be inserted into the liquid separator. Preferably, however, it is provided that the difference between the outer diameter of the support portion and the inner diameter of the liquid separator is small, so that a centering of the gas filter can be achieved to the liquid separator.
  • a further advantageous possibility provides that the gas filter is arranged coaxially to the liquid separator. As a result, a particularly uniform flow of the filter material is achieved on the outer wall of the gas filter.
  • a particularly advantageous possibility provides that the gas filter is arranged in the liquid separator, so that the support portion of the gas filter rests against the bottom of the liquid separator.
  • the gas filter can be arranged to save space, so that no unnecessary space is wasted in the axial direction, so that the maximum level of liquid refrigerant in the refrigerant receiver is not or only very slightly reduced.
  • the bottom of the gas filter has two axial openings, a first opening for the outlet section of the suction tube and a second opening for the inlet section of the suction tube.
  • the outlet portion of the suction pipe may extend through the gas filter so that there is no fluid communication from the outlet portion of the suction pipe to an interior of the gas filter.
  • the inlet portion of the suction pipe may extend into the interior of the gas filter so that the inlet end of the suction pipe is located in the gas filter and thus can receive filtered gaseous refrigerant to discharge it from the refrigerant receiver.
  • an advantageous variant provides that the inlet end of the suction pipe is located in the liquid separator.
  • the liquid separator is arranged at the first end of the refrigerant collecting tank, so that the inlet end of the suction pipe is also disposed at one of the ends of the refrigerant collecting tank. If now arranged this first end in the direction of gravity upwards, thus the inlet end of the suction pipe is also above, so that mainly the gaseous phase of the refrigerant can flow through the inlet end into the suction pipe.
  • a suction pipe 56 is arranged, which has an inlet end 58 with an opening, which is followed by an inlet portion 60 of the suction pipe, and an outlet end 62 with an opening, which is followed by an outlet portion 64.
  • the outlet portion 64 or at least the outlet end 62 engage the outlet 40 of the refrigerant receiver 14 so that refrigerant 12 can flow out of the refrigerant receiver 14 through the suction pipe 56.
  • the refrigerant 12 must first pass through the inlet end 58 into the suction pipe 56.
