Definitions

  • the present invention relates to a refrigerator, in particular for use in a domestic refrigerator, and to a refrigerator, in particular a domestic refrigerator, with such a refrigerator.
  • a refrigeration machine conventionally comprises a refrigerant circuit having a high-pressure section and a low-pressure section, which are connected to one another at two transitions in the refrigerant, driven by a compressor which forms the first transition, and thereby releases heat by condensation in the high-pressure section and absorbs heat by evaporation in the low-pressure section.
  • the refrigerant circuit In order to be able to put the chiller into operation, the refrigerant circuit must be evacuated and filled with refrigerant towards the end of its assembly. Evacuation is conventionally carried out via evacuation connections, i.e. pipes branching off the refrigerant circuit, which are tightly disconnected after the evacuation.
  • the dryer conventionally has a housing in the form of a tube section which is tapered at both ends and is mounted upright in the refrigerant circuit and in the interior of which a moisture-binding material is accommodated, so that the circulated refrigerant flows through it and the refrigerant remaining in the refrigerant circuit during evacuation and disconnection, from the refrigerant entrained moisture binds.
  • a capillary, which forms the second transition to the low-pressure section, and the evacuation connection are introduced into an outlet connection at the lower end of the dryer housing.
  • a disadvantage of this conventional construction stems from the fact that the capillary can only remove the liquid refrigerant from the dryer that is located above an inlet end of the capillary.
  • Refrigerant which is located in the dryer housing below the inlet end and in the evacuation connection from there, cannot drain off and is therefore withdrawn from the refrigerant circuit. How big this amount is depends on how deep the capillary is immersed in the dryer housing and can vary from one chiller to another, leading to individual efficiency deviations of a few percent.
  • the object of the present invention is to provide a refrigeration machine in which the disadvantages described above are avoided.
  • a refrigeration machine with a refrigerant circuit which comprises a high-pressure section and a low-pressure section, which are connected to one another at two transitions, the first transition being formed by a compressor and the second transition being formed by a capillary, and the High-pressure section has a chamber from which an evacuation nozzle goes down, the capillary engages in the evacuation nozzle in an increasing direction from an inlet end of the capillary.
  • the inlet end can be placed lower than in the conventional structure described above, so that a dead volume below the inlet end in which non-circulating refrigerant can collect is reduced. On the one hand, this reduces the amount of refrigerant required to fill the refrigerant circuit, and on the other hand the amount of refrigerant actually circulating and thus the available cooling capacity fluctuate less from one refrigeration machine to another.
  • the chamber mentioned above can be the housing of a dryer and contain a moisture-binding material; however, the applicability of the invention is not limited to this.
  • a second evacuation connection can be provided at a location of the refrigerant circuit as far as possible from the above-mentioned evacuation connection, in particular on the compressor.
  • the evacuation connection can expediently be plug-connected to the outlet connection (and typically fixed and sealed by soldering in the plug-connected state).
  • An advantage of this construction is that a housing and a capillary of known shape can be used and the shape of the evacuation connection piece may have to be adapted to implement the invention.
  • the capillary is passed through a wall of the chamber.
  • the capillary In order to minimize the amount of non-circulating refrigerant trapped in the evacuation port, the capillary should protrude downward into the evacuation port beyond the outlet connection.
  • the capillary can be passed through a wall of the evacuation connection.
  • the inlet end of the capillary is necessarily lower than the outlet connection.
  • a housing or dryer of conventional design can also be used then.
  • a puncture at which the capillary crosses the wall of the evacuation nozzle can be formed on an outside of a curved section of the evacuation nozzle; this can cause the amount of bending and consequently also the effort required Insertion of the capillary into the evacuation socket can be minimized, so that an exact positioning of the inlet end is facilitated.
  • this arc may have a locally lowest point of the evacuation port where liquid refrigerant collects and where the inlet end of the capillary should come as close as possible to minimize the amount of non-circulating liquid refrigerant.
  • the capillary should therefore be inserted at least so far that the inlet end is in the bend.
  • the inlet end should be below a deepest point on an inside of the arch.
  • the evacuation nozzle is tightly clamped off at one end facing away from the chamber. If the evacuation nozzle forms an arch, the capillary can also be inserted from this end in the direction of the chamber into the evacuation nozzle.
  • the curve of the bow should be strong enough so that the capillary cannot pass through it in a straight line; then resistance is felt when the capillary is pushed in as soon as the capillary has to be bent to advance further. When insertion is stopped at this point, the inlet end is at a suitable point.
  • the end of the evacuation nozzle can be closed by pinching it off.
  • the evacuation nozzle can also be continuously inclined from its end attached to the dryer to its end facing away from the dryer and in particular can run in a straight line. When positioning the capillary, however, care must be taken to ensure that the inlet end of the capillary is not so low that it is detected when the evacuation nozzle is disconnected.
  • the invention further relates to a refrigerator, in particular a household refrigerator, with a refrigerator as described above.
  • a refrigerator typically has a heat-insulating housing with one or more storage compartments therein, and at least one evaporator for cooling the at least one storage compartment is part of the low-pressure section, and a condenser arranged on the outside of the housing is part of the high-pressure section.
  • Fig. 1 shows a section through a dryer and a
  • FIG. 2 shows a cross section through the evacuation nozzle from FIG. 1 pushed onto an outlet of the dryer
  • Fig. 3 is a section similar to Fig. 1 according to a second
  • FIG. 4 shows a section through a lower part of a dryer and an evacuation connection piece connected thereto in accordance with a third embodiment
  • FIG. 5 shows a section analogous to FIG. 4 according to a fourth
  • FIG. 6 shows a section analogous to FIG. 4 according to a fifth
  • Fig. 7 is a schematic rear view of a refrigerator with a refrigerator according to the invention.
  • the refrigeration machine has a structure which is known per se and is partly visible in FIG. 7, with a compressor 2, from the outlet of which a high-pressure section a refrigerant circuit.
  • the high-pressure section comprises a pressure line 3, which runs from the compressor 2 to a condenser 4, the condenser 4, a further pressure line 5, which runs from the condenser 4 to the dryer 1, and the dryer 1.
  • the condenser 4 is in the embodiment of FIG. 7 plate-shaped and mounted on the back of a refrigerator body 6 above a machine room 7 accommodating the compressor 2; could alternatively also be accommodated in the machine room 7 itself.
  • a capillary 8 extending from the dryer 1 forms a transition to a low-pressure section of the refrigerant circuit.
  • This comprises an evaporator, not visible in FIG. 6, and a suction line 9, which runs from the evaporator back to the compressor 2.
  • the dryer 1 has a tubular housing 10, which is tapered at an upper and lower end to form an inlet connection 11 and an outlet connection 12, via which refrigerants reach a chamber 14 containing a moisture-binding material 13 in the interior of the housing 10 or escapes from the chamber.
  • a screen 15 is mounted in the chamber 14 to keep the moisture-binding material 13 away from the outlet 12.
  • a section 16 of the capillary 8 lies against the outside of the outlet connector 12.
  • An adjoining upstream section 17 of the capillary 8 projects downward beyond the outlet connector 12.
  • An evacuation connection 18 is pushed onto the outlet connection 12 and the section 16 from below and soldered tightly, so that the upstream section 17 and an inlet end 19 of the capillary 8 are placed below the dryer 1 in the evacuation connection 18.
  • the outlet connector 12 can be provided with an indentation 20, which receives at least part of the cross section of the capillary 8, and / or the evacuation connector 18 can be provided with a corresponding indentation 21.
  • a sleeve 22 may also be formed, the circumference of which is larger than that of a main part 23 of the evacuation nozzle 18, in order to define a depth to which the outlet nozzle 12 and the upstream one Section 17 of the capillary 8 can be inserted into the evacuation connection 18, and thereby also determine the position at which the inlet end 19 of the capillary 8 is located in the evacuation connection 18 after assembly.
  • the main part 23 is largely shaped into an arc 24 in which a deepest point 25 of the evacuation connection 18 is located.
  • liquid refrigerant 33 collects after it has passed the dryer 1, and in order to be able to discharge this liquid refrigerant 33 as completely as possible, the length of the upstream section 17 is dimensioned such that the inlet end 19 is as close as possible to the lowest point 25, but at least below a deepest point 26 of an inside of the arch 24.
  • An end 27 of the evacuation connection 18 facing away from the outlet 12 is still open at the time in which the evacuation connection 18 is connected to the dryer 1 and the capillary 8. Only when the refrigerant circuit is otherwise completely assembled is it evacuated via this end 27, the refrigerant circuit is filled with refrigerant, and the end 27 is disconnected and soldered and thus acquires the shape shown in the figure.
  • FIG. 3 shows a modification of the embodiment of FIG. 1 in a section along a longitudinal axis of the dryer 1.
  • the capillary 8 is here pushed through an opening 28 in a wall of the housing 10, so that it is a bit inside the housing 10 runs and leaves it again via the outlet connection 12.
  • the opening 28 can, as shown in the figure, be provided in a wall of the outlet connector 12 itself; but it could also be placed at the level of the chamber 14, but should then be below the sieve 15.
  • an upstream section 17 of the capillary 8 projects downward beyond the outlet connection 12 and engages in the evacuation connection 18 in order to place the inlet end 19 of the capillary adjacent to the lowest point 25 of the bend 24.
  • the assembly of dryer 1, capillary 8 and evacuation nozzle 18 here requires two soldering processes instead of one in the case of the first embodiment; nevertheless, the assembly can be easier since the capillary 8, if it is already in the opening 28 is soldered or otherwise tightly anchored, can no longer slip when the evacuation nozzle 18 is pushed on, and errors in the positioning of the inlet end 19 can thus be avoided.
  • the evacuation connection 18 can also be pushed into the outlet 18 instead of being plugged onto the outlet 18.
  • the capillary 8 does not extend through an opening of the dryer 1, but rather through the evacuation nozzle 18.
  • the evacuation nozzle 18 can after being plugged onto the outlet 12, be bent sideways, the opening 29 defining a weak point of the evacuation connection 18.
  • the opening 29 is drawn out in the desired manner.
  • the likewise resulting directional deviation of a sloping section 30 of the evacuation connection 18 adjoining the opening 29 additionally facilitates the insertion of the capillary 8, since this can initially follow the course of the section 30 without having to be bent for this.
  • Section 30 is followed by an arc 31 which capillary 8 cannot pass without being bent itself. Consequently, if the capillary 8 is pushed through the opening 29 into the evacuation connection 18 until its resistance increases noticeably, one has the certainty without re-measuring that the inlet end 19 is positioned in the bend 31 and is thus able to use liquid refrigerant 33 to be derived almost completely.
  • FIG. 5 shows a modification of FIG. 4, in which the capillary 8 is inserted into the evacuation nozzle 18 in the opposite direction to FIG. 4.
  • correct positioning of the inlet end 19 can be ensured by inserting the capillary 8 until an increase in the insertion resistance indicates that the arch 31 has been reached.
  • the capillary 8 can be inserted through an opening in the wall of the evacuation nozzle 18; alternatively, there is the possibility of insertion via the end 27 which is still open at this time and is shown open in FIG. 4.
  • FIG. 6 shows a further modification of FIG. 4, in which the elbow of the evacuation connection 18 has been omitted.
  • the evacuation connection 18 here runs continuously and preferably in a straight line from the end pushed onto the outlet connection 12 to the end 27 facing away from the outlet connection 12. Since no elbow limits the insertion depth of the capillary here, it must be ensured in another way that the capillary 8 is immersed deep enough into the evacuation nozzle 18 to largely completely drain the liquid refrigerant 33 therein, but on the other hand not also when the end 27 is disconnected the inlet end 19 of the capillary 8 is blocked. This can be done by inserting a gauge 34 into the still open end 27, which on the one hand has a shoulder 35 abutting the lower end 27 and on the other hand a pin 36 which projects over the shoulder 35 and engages in the evacuation nozzle 18. Then the capillary 8 can be inserted through the opening 27 until its inlet end strikes the tip of the pin 36. This ensures that a sufficient, but not unnecessarily large length of the evacuation connection 18 is available for disconnecting below the inlet end 19.
  • FIG. 7 shows a domestic refrigeration device with a refrigeration machine according to the present invention.
  • the pressure line 5, which connects the condenser 4 to the dryer 1, runs vertically downward from the condenser 4 into the machine room 7.
  • the dryer 1 is accommodated in the machine room 7.
  • the evaporator, which is to be supplied with liquid refrigerant via the capillary 8, is located inside the refrigerator body 6 above the machine room 7, so that the capillary 8 must run upwards again from the dryer 1.
  • the in Figs. 1-6 shown connection of the capillary 8 to the dryer 1 or the evacuation port 18 favors the change of direction required for this in a small space.
  • a second evacuation connection 32 is provided on the compressor 2; in that after the assembly of the refrigerant circuit, the air contained therein is sucked out simultaneously via both evacuation connections 18, 32, a thorough evacuation is achieved in a short time.
