Definitions
- the present invention relates to the storage and regeneration of a cooling fluid.
- ice slurry is to be understood as meaning a cooling fluid comprising two phases of the same body in melting/crystallization equilibrium, for example water to which an antifreeze agent such as salt, alcohol, monoethylene glycol or monopropylene glycol has been added.
- This body in melting equilibrium may also be a eutectic.
- the solid phase in divided form, for example ice microcrystals, is distributed uniformly through the liquid phase, to the extent of obtaining a pasty or viscous consistency of the cooling fluid that is, for example, fluid enough that the said fluid can be pumped.
- the cooling fluids considered according to the invention are therefore obtained, stored, transported and used in mixed and homogenous two-phase form, particularly in a consistency similar to that of a sorbet or ice slurry.
- Cooling fluids comprise a liquid phase and a solid phase in homogeneous mixture. These are themselves generally mixtures of water and alcohol, water and ethylene glycol, water and propylene glycol, water and glycerol, water and ammonia, water and potassium carbonate, water and calcium chloride, water and magnesium chloride, water and potassium acetate, etc; other types of mixture, not containing water, may also be suitable.
- Such cooling fluids perform very well; they absorb heat by the melting of their solid phase, as opposed to conventional liquid cooling fluids which absorb heat only by heating up (appreciable heat).
- Cooling fluid in the liquid phase must be understood as meaning, on the other hand, fluid essentially in the liquid phase, that is to say with a low, if not zero, concentration of microcrystals.
- Document U.S. Pat. No. 2,902,839 discloses a device for storing and regenerating a cooling fluid, in two-phase form, but not in the form of ice slurry, intended to circulate solely in liquid form through a heat transfer circuit.
- the latter comprises one or more heat exchangers for the exchange of heat between the cold and liquid-form cooling fluid and the outside.
- Said device comprises:
- a circulation means of the pump type for circulating the cooling fluid, drawn from said compartment in the liquid state in the cold state, in the heat-exchange circuit and for reinjecting it into said compartment;
- a two-phase recycling and cooling circuit for recycling and cooling the cooling fluid, within said compartment, comprising a tapping point at the lower part of said compartment, said recycling circuit incorporating the indirect heat-exchange means and comprising a means for withdrawing/discharging the cooling fluid.
- the indirect heat-exchange means is an exchanger with a scraped surface, generating a mass setting of the cooling fluid over a scraping surface. Separation of the cooling fluid in solid form from the scraping surface requires significant force, thus going against the idea of reducing the operating energy consumption of the device.
- EP 0 629 826 discloses a cold transfer device comprising a vertical compartment intended to store and to supply a heat-transfer circuit with a cooling fluid of the ice slurry type.
- the device comprises an indirect heat-exchange means for the exchange of heat between a refrigerant fluid and the cooling fluid, this device being placed outside the storage chamber. It is pumped in liquid phase from a lower level of the storage compartment to be reinjected at a higher level once it has been enriched with microcrystals of the solid phase.
- An extraction means is also provided for supplying the heat-transfer circuit with cooling fluid of the ice slurry type.
- This extraction means comprises a cone opening onto a duct in the storage compartment. The opening of the cone is at a higher level and where the cooling fluid is rich in solid phase (ice microcrystals).
- An agitating means is arranged in the cone, so as to create turbulence in the extracted cooling fluid, regenerating the ice slurry.
- Such a device does not allow precise control over the concentration of microcrystals in the cooling fluid of ice slurry type extracted to feed the heat transfer circuit.
- the supply to the indirect heat-exchange means is under the hydraulic pressure for the cooling fluid contained in the storage compartment. This may prove to be troublesome during maintenance operations especially, when the storage compartment is very large.
- a significant storage head of ice slurry may, with certain mixtures, lead to a stratification which may appreciably damage the quality of the ice slurry injected into the installation. Drying-out of the top layer may occur, leading to non-optimum temperature. This disadvantage is all the more pronounced if the ice slurry is not in constant use.
- the object of the present invention is to store and to regenerate, constantly, a cooling fluid, of the ice slurry type, so that it is permanently operational, even after long periods of shut down.
- Another object of the present invention is to optimize the consistency of a cooling fluid of the ice slurry type, that is to say to optimize the concentration of microcrystals in the cooling fluid and, in particular, to control this concentration, in order to obtain the maximum storage.
- Another objective of the present invention is to control and to alter, as appropriate, this concentration of microcrystals with a view to improving or adapting the refrigerating properties of the cooling fluid of the ice slurry type, in use.
- An additional object of the present invention is to simplify the installations employing such a cooling fluid, on the one hand, and to facilitate the maintenance operations, on the other.
- the device comprises:
- step (i) the cooling fluid obtained in (h) is used to carry out step (a) by tapping cooling fluid conditioned in the from of ice slurry from said other compartment and it is reinjected, downstream of the heat exchanger or exchangers of the heat-transfer circuit into the storage and regeneration compartment, and/or for example at the inlet to the indirect heat-exchange means.
- the indirect heat-exchange means comprises:
- a crystallization chamber provided, on the one hand, with at least one tapping orifice for solid-phase-lean cooling fluid, communicating with the storage and regeneration compartment in the lower part and, on the other hand, an expulsion opening for expelling solid-phase-rich cooling fluid ( 4 );
- At least one hollow disk mounted fixedly in the crystallization chamber in contact with the circulating stream of cooling fluid from the tapping orifice to the expulsion opening, said disk having, passing through it internally, a refrigerant fluid in the course of evaporating or some other cooling fluid at a lower temperature;
- a set of sweeping arms which are mounted on a spindle which is driven in rotation by a geared motor unit, and which arms are arranged with respect to the disk(s) in such a way as to sweep its surface in contact with the cooling fluid and to expel the solid-phase-rich cooling fluid toward the expulsion opening.
- the indirect heat-exchange means comprises a set of hollow disks which are arranged parallel to one another and spaced apart, and in that at least some of the sweeping arms, mounted fixedly on the spindle of the geared motor unit are angularly offset from one another and, from one disk to the next or from one side of a disk to its adjacent side, to force the cooling fluid to circulate within the crystallization chamber, the sweeping arms together thus constituting the withdrawing/discharging means for recycling the cooling fluid within the storage and regeneration compartment.
- the device according to the invention comprises a number of indirect heat-exchange means associated with one and the same storage and regeneration compartment and distributed about said compartment, which runs concentrically around the sole other conditioning compartment.
- the device according to the invention has the advantage of keeping the cooling fluid in motion throughout its circulation through the two compartments, storage and regeneration, and conditioning, respectively, particularly in the indirect heat-exchange means, thus avoiding any setting that carries the risk that the circulation will become blocked by the frozen fluid.
- Another advantage is associated with the large amount of cooling fluid that can be stored in two-phase form in the melting equilibrium, with a view to supplying any cold-transfer circuit.

- FIG. 13 is an exploded section on XIII-XIII of FIG. 12.
- FIG. 1 is a view in section of a storage, regeneration and conditioning device according to the invention.
- This device comprises a storage and regeneration compartment 2 containing a cooling fluid 4 in the two-phase state in melting/crystallization equilibrium.
- the device according to the invention also comprises an indirect heat-exchange means 6 for the exchange of heat between a refrigerant fluid and the cooling fluid 4 essentially in the liquid phase.
- This indirect heat-exchange means 6 is associated with the storage and regeneration compartment 2 .
- a circulation means 8 of the pump type depicted for example in FIG. 2 is provided to circulate the cooling fluid 4 tapped from the storage and regeneration compartment 2 in a heat-transfer circuit 10 comprising one or more heat exchangers 12 .
- the heat-transfer circuit 10 opens downstream of the heat-exchange means 12 into the storage and regeneration compartment 12 .
- the heat transfer circuit 10 thus opens for example into the storage and regeneration compartment 2 , via an opening 2 a.
- the volume into which the heat-transfer circuit 10 opens is preferably partially separated or demarcated from the remainder of the storage and regeneration compartment 2 and may in its lower part comprise gratings 14 able to contain the cooling fluid 4 in solid phase in said storage and regeneration compartment 2 .
- the gratings 14 thus constituting a filter, may be omitted when the storage and regeneration compartment 2 is large enough to obtain good separation of the cooling fluid 4 in the liquid phase towards the bottom.
- the storage and regeneration compartment 2 delimits a central separation region 2 b including the lower part arranged, on the one hand, between the gratings 14 and, on the other hand, between two boundary walls 16 and 18 .
- the first boundary wall 16 provides partial delineation between the storage and regeneration region 2 b and the region comprising the indirect heat-exchange means 6 .
- the second boundary wall 18 provides partial delineation between the storage and regeneration region 2 b and another conditioning compartment 20 in the form of an ice slurry, of said cooling fluid 4 .
- This second compartment 20 is connected to the heat-transfer circuit 10 via an opening 22 associated with the circulation means 8 .
- the other conditioning compartment 20 is also supplied with cooling fluid 4 of the ice slurry type.
- the device according to the invention also comprises a two-phase recycling and cooling circuit for recycling and cooling the cooling fluid 4 within the storage and regeneration compartment 2 .
- This two-phase recycling and cooling circuit comprises at least one tapping point 24 at the lower part of said storage and regeneration compartment 2 .
- the gratings 14 are spaced away from the corresponding side walls 2 e to constitute flow corridors opening onto the tapping point or points 24 , supplying the indirect heat-exchange means 6 .
- the recycling and cooling circuit also incorporates the indirect heat-exchange means 6 and further comprises a means for withdrawing and discharging the cooling fluid 4 .
- the cooling fluid 4 is thus drawn into the indirect heat-exchange means 6 , as depicted for example in FIG. 4 by the arrows “A”.
- the other conditioning compartment 20 and the indirect exchange means 6 are, for example, arranged one on each side of the central storage and regeneration region 2 b , mainly constituting the storage and regeneration compartment 2 for the cooling fluid 4 .
- the other conditioning compartment 20 is supplied at an upper level with at least some of the solid-phase-rich cooling fluid 4 outside of the indirect heat-exchange means itself, and this is done using introduction means 72 .
- a complementary tapping point on the storage and regeneration compartment 2 this being at the lower part, associated with means 26 for injecting cooling fluid 4 in liquid phase into said other conditioning compartment 20 is also provided.
- the cooling fluid 4 in liquid phase is thus conveyed to the other conditioning compartment 20 for example with the aid of a distribution tube 28 arranged more or less in its central part.
- a mixing member 30 is also provided to collaborate with the other conditioning compartment 20 so as to mix the liquid and solid phases of the cooling fluid 4 which are contained in said other compartment 20 .
- the device according to the invention also comprises a level detector 32 for determining the fill level of the other conditioning compartment 20 with the cooling fluid 4 in the form of ice slurry.
- the device also comprises a measuring member 34 for determining the solid phase concentration of the cooling fluid 4 in the form of ice slurry in the other conditioning compartment 20 .
- the measuring member 34 is for example produced with a temperature sensor, or an electrical conductivity or capacitive sensor or with means for measuring opacity, which is associated with appropriate analysis means, of the electronic or microprocessor type.
- the circulation means 8 allows the cooling fluid 4 to be reinjected downstream of the heat exchanger or exchangers 12 of the heat-transfer circuit 10 , for example into the storage and regeneration compartment 2 , via an orifice 2 a formed therein at a lower level.
- the circulation means 8 and the heat-transfer circuit 10 are also or solely connected to the indirect heat-exchange means 6 so that the cooling fluid 4 can be reinjected directly thereinto downstream of the heat exchanger or exchangers 12 .
- the indirect heat-exchange means 6 is depicted schematically more specifically in FIGS. 2, 3 and 4 .
- the indirect heat-exchange means 6 comprises a crystallization chamber 6 a provided, on the one hand with at least one tapping orifice 6 b for tapping of solid-phase-lean cooling fluid 4 , communicating via the tapping orifices 24 with the storage and regeneration compartment 2 of the lower part and, on the other hand, with an expulsion opening 6 c for expelling solid-phase-rich cooling fluid 4 .
- the indirect heat-exchange means 6 also comprises at least one hollow disk 40 mounted fixedly in the chamber 6 a , in contact with the stream of cooling fluid 4 circulating from the tapping orifice 6 b to the expulsion opening 6 c .
- the hollow disk 40 has passing across it internally a refrigerant fluid in the course of evaporating, for example NH 3 .
- the hollow disk or disks 40 are supplied with this refrigerant fluid via a refrigeration unit 50 arranged for example beside the heat-exchange means 6 .
- the refrigerant fluid may be replaced by another cooling fluid, different from the one circulating in the heat-transfer circuit 10 , but colder.
- the indirect heat-exchange means 6 also comprises a set of sweeping arms 60 mounted on a spindle 62 , which is driven in rotation by a geared motor unit 64 .
- the sweeping arms 60 are arranged with respect to the hollow disk(s) 40 in such a way as to sweep their surface in contact with the cooling fluid 4 and to expel the enriched cooling fluid 4 in the process of being supercooled toward the expulsion opening 6 c of the chamber 6 a . Crystallization of the cooling fluid 4 thus occurs directly in the discharged and expelled stream.
- the expulsion of the cooling fluid 4 and more precisely the discharge of this cooling fluid 4 is depicted schematically by the arrows “R” as shown in FIGS. 4 and 3.
- the return of the cooling fluid 4 or of the ice slurry is downstream of the heat exchangers 12 .
- the or each hollow disk 40 has a central passage 41 through which the spindle 62 passes.
- the cooling fluid 4 is thus drawn through the tapping openings 6 b to then circulate from the passage or passages 41 to the periphery of each hollow disk 40 , by a centrifugal effect.
- FIGS. 12 and 13 One exemplary embodiment of a hollow disk 40 is depicted in FIGS. 12 and 13.
- the hollow disk 40 comprises, for example, two lateral plates 42 and an intermediate plate 43 , each one provided with a central passage 41 .
- the intermediate plate 43 cut into serpentines 43 a , is sandwiched and trapped closely and with sealing between the lateral plates 42 .
- the serpentines 43 a thus produce the circulation path for a refrigerant fluid, the circulation of which is depicted schematically for example by the arrows Fe and Fs in FIGS. 3 and 12.
- the arrows FE and FS correspond respectively to the inlet and outlet directions of the refrigerant fluid circulating in the hollow disk 40 .
- the indirect heat-exchange means 6 comprises, for example, a set of hollow disks 40 which are arranged parallel to one another and spaced apart. At least some of the sweeping arms 60 mounted fixedly on the spindle 62 of the geared motor unit 64 are offset angularly from one another, from one disk to the next, or from one side of a disk to its adjacent side, to force the cooling fluid 4 to circulate within the crystallization chamber 6 a .
- the set of sweeping arms 60 as a whole thus constitutes intake and discharge means for recycling the cooling fluid 4 within the storage and regeneration compartment 2 .
- the rotation of the sweeping arms 60 is depicted schematically by the arrow “V” in FIGS. 3 and 4.
- the expulsion opening 6 c is shaped, positioned and orientated in such a way as to expel the solid-phase-rich cooling fluid 4 to the other conditioning compartment 20 , thus constituting means of introduction thereinto.
- the sweeping arms 60 may adopt different shapes depicted by way of example in FIGS. 5 to 9 .
- the sweeping arms 60 may thus be curved as depicted in FIGS. 6 and 8, or elbowed as depicted in FIGS. 5 and 7.
- the number of sweeping arms 60 for sweeping the surface of a hollow disk may also vary. Specifically, it is possible, as depicted in FIGS.
- FIG. 9 shows an exemplary embodiment in which the adjacent sweeping arms 60 are angularly offset from one another.
- the expulsion opening 6 c is positioned and orientated in such a way as to expel the solid-phase-rich cooling fluid 4 into the storage and regeneration compartment 2 , and more specifically into the central region 2 b at an upper level.
- the introduction means 72 then extend at an upper level into said storage and regeneration compartment 2 .
- They comprise moving blades 70 designed to push the cooling fluid 4 toward and into the conditioning compartment 20 .
- the moving blades 70 are advantageously mounted on a chain or a belt driven by a geared motor unit 74 .
- the moving blades 170 are mounted on horizontal arms 172 , themselves fixed on a vertical spindle 174 driven by a geared motor unit 176 .
- the moving blades 170 are, for example, orientable with respect to their horizontal mounting arms 172 , as depicted schematically in FIG. 11 by the arrows “W”.
- the device according to the invention comprises a plurality of indirect heat-exchange means 6 (just one of which is depicted in FIG. 11), which are associated with one and the same storage and regeneration compartment 2 .
- the indirect heat-exchange means 6 are distributed about the storage and regeneration compartment, which itself runs concentrically around the sole other conditioning compartment 20 .
- the wall 20 a delimiting the other conditioning compartment 20 has a preferred height that does not substantially alter the solid-phase cooling fluid 4 supply from the blades 170 .
- a mixing member 30 immersed in the other conditioning compartment 20 is, for example, mounted on the spindle 174 and rotates therewith.
- the operation of the device depicted in FIGS. 10 and 11 is, for the remainder, identical to that of the device depicted in FIG. 1.
- the refrigeration source 50 may be placed beside, underneath, or completely independently of the indirect exchange means 6 .
- the admission of cooling fluid 4 in liquid phase into the indirect heat-exchange means 6 or, more specifically, into the chamber 6 a is via ducts 6 d opening into the storage and regeneration compartment 2 .
- the device according to the invention makes it possible to employ a method for storing and regenerating a cooling fluid in two-phase form and intended to supply one or more heat exchangers 12 .
- This method makes it possible to illustrate the operation of such a device according to the invention.
- a cooling fluid 4 comprising a solid phase in melting/crystallization equilibrium with a liquid phase
- said cooling fluid 4 is circulated through the circuit comprising the heat exchangers 12 and into a storage and regeneration compartment 2 associated with an indirect heat-exchange means 6 .
- the cooling fluid 4 is constantly stored in the storage and regeneration compartment, thus allowing the liquid phase and the solid phase of said fluid to separate.
- Tapping the cooling fluid 4 from said storage and regeneration compartment 2 , essentially in the liquid phase, and circulating it through the indirect heat-exchange means 6 allow said fluid to be converted to a solid phase, which is broken down into microcrystals. The latter, rich in microcrystals, is then reinjected into the storage and regeneration compartment 2 .
- cooling fluid 4 rich in microcrystals or solid phase is separated off and stored in the other conditioning compartment 20 in the form of ice slurry.
- Some of the cooling fluid 4 in liquid phase, or lean in solid phase, taken from the storage and regeneration compartment 2 is then injected into said other conditioning compartment 20 so as to mix the solid and liquid phases of the cooling fluid 4 in said other conditioning compartment 20 .
- the ice slurry mixed in the other conditioning compartment 20 is thus ready to be drawn or pumped into the heat-transfer circuit 10 .
- the cooling fluid 4 or ice slurry is returned downstream of the heat exchangers 12 either directly into the crystallization chamber 6 a or into the storage and regeneration compartment 2 at a lower level.
- the method also consists in altering the amount of solid-phase-lean cooling fluid 4 injected into the other conditioning compartment 20 .
- the method according to the invention also consists in determining, in the conditioning compartment 20 , the solid-phase concentration and in altering this concentration as necessary by acting on the amount of solid-phase-lean cooling fluid 4 injected into the other conditioning compartment 20 .
- the method according to the invention it is also possible to determine the fill level of the other conditioning compartment 20 with cooling fluid of the ice slurry type, and to use the result of this determination to act on the angle of incidence of the blades 170 or the speed at which the blades 70 , 170 move. It is also possible to accelerate, slow down or if necessary interrupt the various operations of said method and, in particular, operations (f), (g) and (h). It is thus possible to influence the orientation of the blades 170 in order to alter the amount of solid phase cooling fluid 4 reinjected into the other conditioning compartment 20 .
- the amount of cooling fluid 4 in the liquid phase reinjected into the other conditioning compartment 20 is governed by the measurement member 34 determining the microcrystals concentration.
- This movement is advantageously toward the crystallization chamber 6 a .
- the movement of the liquid-phase cooling fluid 4 toward the crystallization chamber 6 a is thus encouraged at the same time as the movement of the microcrystal-rich cooling fluid toward the other conditioning compartment 20 .
- the blades 70 and 170 constantly keep the crystal-rich or solid-phase upper part in the pasty state, and prevent the crystals from setting en masse. This device is necessary in large-capacity units, for example those used discontinuously.
