Definitions

  • the invention relates to a removal device for removing a fluid from a refrigeration system.
  • the removal device has a compressor and a cooling device through which the fluid flows, which has a pipeline arrangement through which the fluid flows, with a plurality of interconnected pipeline elements.
  • the tubing assembly has a fluid inlet and a fluid outlet.
  • the fluid may typically be a condensable gas.
  • the cooling device is used to cool the compressor, which removes condensable gases from a process.
  • Such removal devices are used in the maintenance of refrigeration systems or air conditioning systems, such as air conditioning systems.
  • the basic principle of such a cooling device is that a previously compressed fluid flows through the fluid inlet into the piping arrangement and condenses as it flows through the piping arrangement. There are Heat to the outside before it leaves the piping arrangement as a liquid through the fluid outlet.
  • US Pat. No. 6,779,359 B2 discloses a similar extraction device for removing a fluid from a refrigeration system.
  • the fluid must be completely removed from the pipeline assembly.
  • a flushing method in which the piping arrangement is controlled by a pressurized flushing fluid, e.g. Air is flowed through and later filled with another fluid refrigerant.
  • a pressurized flushing fluid e.g. Air is flowed through and later filled with another fluid refrigerant.
  • additional pumps and valves are required to first pump the refrigerant out of the piping arrangement and then to pump the purge gas through the piping.
  • the invention has for its object to provide an easier to clean removal device for removing a fluid from a refrigeration system.
  • the removal device according to the invention is defined by the features of claim 1.
  • the piping arrangement comprises a plurality of interconnected piping elements having a fluid inlet disposed above the piping elements and a fluid outlet disposed below the piping elements, the piping elements each being inclined at an angle ⁇ to a horizontal plane such that all the fluid entering through the fluid inlet is open with the fluid outlet is automatically moved from gravity to the fluid outlet.
  • the angle ⁇ can in this case be between 1 ° and 4 °, preferably between 2 ° and 3 ° and in particular about 2.5 °. Due to the inclined arranged, successively flowing through the fluid pipe elements, the fluid can flow with open fluid outlet by the action of gravity without additional pumps or valves from the fluid outlet.
  • the fluid With open fluid inlet and / or open Fluid outlet, ie, at atmospheric pressure within the piping arrangement, the fluid is preferably a liquid refrigerant. The fluid can flow out completely from the fluid outlet without requiring any movement or pivoting of the removal device.
  • the pipeline elements are preferably straight and arranged one after the other in the fluid flow direction.
  • the pipeline elements can be stacked one above the other.
  • successively arranged pipe elements are advantageously inclined by an angle ⁇ against each other.
  • the angle ⁇ can be between 1 ° and 9 °, preferably between 3 ° and 7 ° and in particular about 5 °. For a typical refrigerant, this results in advantageous flow velocities for a uniform and complete outflow of fluid from the pipeline elements.
  • the successively arranged in the fluid flow direction pipe elements are preferably connected in each case by U-shaped connecting pipes, which are arranged in a plane inclined relative to a horizontal plane by an angle ⁇ .
  • the angle ⁇ may be between 10 ° and 50 °, preferably between 25 ° and 35 ° and in particular about 30 °.
  • the pipeline elements are advantageously arranged stacked in two different, mutually parallel planes, wherein the two planes are each inclined relative to a vertical plane and relative to a horizontal plane.
  • the angle of inclination ⁇ of these planes with respect to the vertical plane is preferably between 5 ° and 35 °, more preferably between 15 ° and 25 ° and in particular about 20 °.
  • the pipeline elements arranged one after the other in the fluid flow direction should be arranged in different ones of the two planes. This results in a Space-saving arrangement of the piping elements, from which the fluid can flow out completely with the fluid outlet open.
  • the cooling device is provided with cooling fins for the piping arrangement, each having openings arranged along a first straight line for the pipe elements of the first level and along a second, parallel to the first straight line recesses for the pipe elements of the second level.
  • These cooling fins may be arranged side by side and parallel to one another, wherein the openings of the cooling fins contact the pipe elements of the first level and the recesses contact none of the pipe elements. A heat transfer then takes place only between the pipe elements of the first level and the cooling fins.
  • the recesses for the second level piping elements allow for easy mounting of the cooling fins on the piping assembly.
  • the cooling device advantageously has, in the direction of flow in front of the pipeline arrangement, a compressor through which the fluid flows and which is connected to the fluid inlet of the pipeline arrangement.
  • a compressor through which the fluid flows and which is connected to the fluid inlet of the pipeline arrangement.
  • the removal device 10 which consists of the cooling device 11, upstream in the fluid flow direction of the compressor 14 and further upstream in both directionssabsperrender quick release coupling 16 and in both directionssabsperrendem plug 18, and connected downstream in both directionssabsperrender quick-release 20 andsabsperrendem plug 22 in both directions.
  • the cooling device 11 consists of a piping arrangement 12 and cooling fins 34a, 34b on the piping arrangement.
  • the pipe assembly 12 consists of a plurality of straight pipe elements 24,26, a fluid inlet 28, a fluid outlet 30 and a plurality of connecting tubes 32, the two fluid flow in succession arranged pipe elements 24,26 fluidly connect.
  • the pipe elements 24 are arranged one above the other in a first plane, which is parallel to a second plane in which the remaining pipe elements 26 are arranged one above the other.
  • a first-level tubing member 24 is disposed between second-level tubing planes 26.
  • a second level tubing element 26 is disposed in the fluid flow direction between first level tubing elements 24.
  • a first-level piping element 24 is connected by two connecting pipes 32 to two second-level piping elements 26.
  • FIG. 5 As in Fig. 5 is shown, adjacent, in the fluid flow direction successively arranged pipe elements 24,26 different levels against each other by an angle ⁇ of about 5 °, ie, 5 ° or of 5.1 °, inclined to each other.
  • the plane of the connecting tubes 32 is inclined relative to a horizontal plane by an angle ⁇ of about 30 °.
  • Fig. 7 It can be seen that each pipe element 24,26 is inclined relative to a horizontal plane by an angle ⁇ of about 2.5 °. From the Figures 2 and 3 It can be seen that the plane of the pipe elements 24 and the plane of the pipe elements 26 parallel to each other and each at an angle ⁇ are arranged inclined with respect to a vertical plane.
  • the angle ⁇ is about 20 °.
  • FIGS. 6 and 7 show the parallel to each other along the pipe assembly 12 arranged cooling fins 34a, 34b.
  • the cooling fins 34a, 34b are each provided with holes 36 in the form of holes for the first level piping elements 24.
  • each cooling fin 34a, 34b is provided with recesses 38.
  • the openings 36 and the recesses 38 are each arranged along a straight line. According to the two levels for the pipe elements 24,26 these two straight lines are also arranged parallel to each other. While the openings 36 completely surround the first-level tubing elements 24 and contact them in a heat-conducting manner, no contact with any tubing element 24, 26 and in particular no heat transfer is provided in the region of each recess 38.
