Definitions

  • the present invention relates to a refrigeration device for unit cooling of cylindrical objects or cylindrical packages containing liquids.
  • the technical sector of the invention is that of equipment falling within the framework of the refrigeration industry.
  • the present invention aims to remedy this drawback.
  • the objective to be achieved is a refrigerating apparatus comprising an evaporator allowing the introduction of the container to be cooled not only by its ends but also laterally, which makes it possible for example to cool bottles comprising reliefs (mention of capacity, trade mark. ..) or crimped bottom boxes.
  • the refrigerating apparatus for cooling cylindrical objects or cylindrical packages containing liquids and comprising in the direction of movement of the refrigerating fluid: a compressor, a condenser, a pressure reducer and an evaporator, characterized in that said evaporator is constituted by an enclosure formed by a tight double wall around its periphery, which enclosure adopts the general shape of a cylinder open at its ends and over the height of the enclosure and whose internal diameter is substantially equal to that of said object or said packaging on which the enclosure is in contact during the refrigeration phase.
  • the enclosure is of a cross section at least semi-circular.
  • the evaporator comprises a network of pipes in loops occupying almost the entire surface of the evaporator and in which network circulates the refrigerating fluid.
  • said pipes are of a flattened cross section.
  • the internal face of the enclosure is smooth so as to be tightly pressed against the object or the cylindrical package to be cooled.
  • the suction duct and the tubing coming from the regulator open into the double wall of the enclosure or into pipes of said network and in the vicinity of one of the two edges which delimit its lateral opening, to allow free elastic deformation of the evaporator.
  • the result of the invention is a refrigeration device allowing the unitary cooling of cylindrical objects or cylindrical containers containing liquids such as for example drinks.
  • the evaporator which equips said device offers the particularity of being self-tightening, that is to say of applying its internal face against the wall of the container or of the object to be cooled.
  • This self-tightening is based on the principle of the elastic deformation of a metallic hollow body subjected to a pressure variation of a fluid.
  • This principle is already applied in many devices such as the so-called “Bourdon tube” pressuremeters comprising a curved tube, the open inlet end of which is fixed and the opposite closed end acts mechanically on a movable member (needle, breaker, etc.). ) when the tube deforms under the effect of the fluid pressure.
  • the invention proposes to use to obtain self-tightening of the container by the evaporator.
  • FIGS. 1 and 2 of the drawing illustrate an apparatus and an evaporator according to the invention in one embodiment.
  • the refrigeration apparatus comprises an evaporator of a generally cylindrical shape 1 for closely surrounding a cylindrical object, a compressor 2, a condenser 3 for example of the ventilated type and a pressure reducer 4, for example a capillary helical coil.
  • Said evaporator 1 consists of two curved plates la / lb, for example of aluminum alloy, which plates are curved along radii Rl / R2, are parallel to each other and are joined at their upper, lower and lateral ends 1c / 1d / 1e / 1f where they are joined by hot rolling or by welding.
  • Said evaporator thus forms a double wall which delimits an enclosure in which the refrigerant circulates.
  • the evaporator adopts the general shape of a horseshoe and is open at its upper and lower ends and also on part of its lateral wall, the lateral opening being thus delimited by the edges the / If of the double wall.
  • the evaporator 1 can be provided with a more or less wide opening as shown in FIGS. 1, 3 and 4. So that the objects to be cooled can be introduced laterally (FIGS. 3 & 4), it can be formed of a double wall covering the surface of a half-cylinder.
  • the double wall can cover almost all of a cylinder.
  • the figure illustrates an evaporator which covers approximately three-quarters of a cylinder.
  • the duct 5 is connected on the one hand to the pressure reducer 4, which is according to this example a capillary, and on the other hand to the upper part of the evaporator 1, for example at the top and on the edge side.
  • the compressor 2 is connected by the conduit 6 to the upper part of the evaporator, this conduit terminating in the vicinity of the edge If.
  • the duct 6 is connected to the suction of the compressor 2.
  • the cooling fluid discharged by the compressor is sent through the pipe 7 into the condenser 3 and is circulated first in the regulator 4 and then in the evaporator 1 by being admitted into the latter by the tube 5.
  • the fluid admitted into the double wall la / lb scans the enclosure as is represented by the arrows FI / F2.
  • the oil entrained by the fluid is collected at the lower part of the exchanger and is evacuated by a tube 8 which connects the lower part of the enclosure and the compressor 2.
  • This tube 8 is of very small section to avoid the fluid entrainment refrigerant.
  • this tubing 8 is located on the side of the edge 1f of the evaporator, below the pipe 6 and is connected to the latter.
  • the evaporator although of a design similar to that which has just been described comprises (FIGS. 5 and 7) a network of pipes in loops.
  • the internal wall 1b is smooth to favor the exchange in contact with the object to be cooled while the external wall 1a is corrugated to form pipes 1g of a flattened cross section.
  • FIG. 5 of the drawing The circulation of the cooling fluid in an evaporator of this type is illustrated in FIG. 5 of the drawing.
  • the pipes 1g extend in the direction of the length of the evaporator, which is shown flat.
  • the pipes lg are thus parallel to one another and are connected to each other by forming loops.
  • the fluid is admitted to the upper part of the evaporator and is sucked in at its lower part by circulating in the direction of the arrows. In this way, the fluid concerns the entire surface of the evaporator.
  • FIG. 6 of the drawing An apparatus comprising an evaporator of this type is illustrated in FIG. 6 of the drawing, the parts 2, 3, 4 and 7 of which are identical to those of FIG. 2 previously described.
  • the refrigerant is admitted through the pipe 5, which is connected to a pipe lj which opens into the upper part of the extreme high pipe lg.
  • the outlet of the fluid is carried out by a conduit lh having the same section as the conduit Ij, which conduit lh opens out at the bottom of the extreme low line Ig.
  • the fluid suction pipe lh extends over part of the height of the enclosure and is brought below and in the vicinity of the delivery pipe. entry lj.
  • the duct 1h is connected to the compressor by means of a stopper 9.
  • the evaporator can deform freely due to the fact that the two pipes 5 and 9 are situated on the same side and in the vicinity of the edge 1a of the evaporator, the other edge If thus being freed from all mechanical stress.
  • the evaporator according to Figures 5, 6 and 7 is for example produced by the hot rolling and inflation process of the refrigeration circuit, known as "Rollbond".
  • the pressure in the evaporator being that of the low pressure branch (outlet of the expansion valve-evaporator-suction of the compressor) and variable depending on the refrigerant used and the conditions of use, is less than or at most, equal to half the pressure prevailing in the high pressure branch (compressor discharge, condenser, regulator inlet), when the system is operating normally. When the compressor stops, this low pressure is equalized with the high pressure, at an average pressure HP - BP + BP.
  • the evaporator undergoing greater internal pressure will tend to unwind, making it possible to place the object to be cooled in its center 10.
  • the pressure falling in the evaporator will close on the object, ensuring a satisfactory thermal connection, and a good performance of the device.
  • K is proportional to ⁇ , and inversely proportional to the distance e.
  • the most interesting application is the cooling of cylindrical objects, part of an evaporator rolled to its exact size (small beer kegs, bottles, cylindrical cans, etc.) which must be quickly cooled over their entire outer surface. to avoid thermal stratification of the liquid (hot at the top, cold at the bottom), in a space-saving device; the replacement of the empty container 10 being carried out when the the device.
  • a change of a few millimeters in the circumference formed by the evaporator is sufficient to tighten or release the object 10.
  • This system applies validly for the refrigeration of any object of cylindrical or approaching section, comprising a continuous curve over at least half of its perimeter, allowing lateral or extremity introduction into the evaporator.
  • the evaporator I may include one or more toggle closure devices or the like, for manually obtaining the application of the internal wall 1b of the enclosure against the cylindrical objects or containers to be cooled, which locking device is fixed at the double wall, in the vicinity of each of the lateral edges le / lf of the evaporator.
