Definitions
- the invention relates to an installation and a method for producing cold by a thermochemical system, in particular for freezing various products or for producing chilled water.
- a reversible sorption can be an absorption of a gas by a liquid, an adsorption of a gas on a solid, or a reaction between a gas and a solid.
- a reversible sorption between a sorbent S and a gas G is exothermic in the direction of the synthesis S + G -> SG, and endothermic in the direction of the decomposition SG - S + G. In a change of liquid phase / gas of G , the condensation is exothermic and evaporation is endothermic.
- P and T being respectively the pressure and the temperature
- ⁇ H and ⁇ S respectively being the enthalpy and the entropy of the phenomenon (decomposition, synthesis, evaporation, condensation) involved
- R being the constant of the ideal gases.
- the endothermic stage can be used in an installation of this type for freezing various products (in particular water for obtaining ice cubes) or for the production of cold water.
- EP0810410 describes a device comprising a reactor and an evaporator / condenser connected by a pipe fitted with a valve.
- the reactor is the site of a thermochemical reaction or a solid-gas adsorption. It includes means for heating the solid which it contains and means for removing the heat from the exothermic synthesis reaction, these means being constituted either by a heat exchanger or by increasing the thermal mass of the reactor.
- the reactor is arranged so that, with its content, it has a sufficient thermal mass to absorb the heat produced during the exothermic reaction.
- the method of managing this device consists in putting the evaporator / condenser in communication with the reactor when the evaporator / condenser is filled with the working gas in liquid form, which has the effect of cooling the evaporator / condenser by evaporation. , then switch on the means intended to heat the solid in order to discharge and condense the working gas towards one evaporator / condenser.
- the start-up of the means intended to heat the solid in the reactor begins before the previous step is completed.
- the cold produced at the evaporator / condenser can be used to produce cold water or ice cubes.
- the cycle times are relatively long because the regeneration of the device takes place at high temperature Th and the cooling of the reactor takes place at room temperature To. Consequently, the reactor travels a thermal amplitude between the relatively high regeneration temperature and the ambient temperature which induces a low coefficient of performance.
- EP-0835414 describes a process for producing cold and / or heat for thermochemical phenomena using a gas G, in an installation comprising two reactors (Ri, R 2 ) respectively containing a salt (Si, S 2 ), an evaporator for gas G and a condenser for gas G.
- the equilibrium temperature of the salt Si is lower than the equilibrium temperature of the salt S 2 at a given pressure.
- the reactors are placed in thermal contact so as to be able to exchange heat.
- the reactors, the evaporator and the condenser are connected in a selective manner using pipes fitted with valves. In the initial state, the reactors and the condenser are in communication, at the condenser pressure.
- one of the reactors is in synthesis mode while the other reactor is in decomposition mode. In this operating mode, the cold is produced at a single temperature level, that is to say at the evaporation temperature in one evaporator.
- the aim of the present invention is to provide a method and an installation allowing very high volume refrigeration production, for example of the order of 200 kW / m 3 , with greatly reduced cycle times and more attractive performance, in particular for the instant and rapid production of cold water, or for the rapid freezing of various products (for example for the production of ice cubes).
- the method according to the present invention for producing cold by a thermochemical system comprises three reversible phenomena using gas G, in three chambers (EC), (1) and (2), the respective equilibrium temperatures T E ( E O , T E ( D and T E ⁇ 2 ) at a given pressure being such that T E ( EO ⁇ T E ⁇ 2 ) ⁇ T E (i), the chambers (1) and (2) being in thermal contact It is characterized in that, starting from a state in which the three enclosures are at ambient temperature at the same pressure, in a first phase, the enclosure (1) is isolated, the enclosures are placed in communication (EC ) and (2) to cause the exothermic synthesis in (2), the heat formed being absorbed by the enclosure (1); in a second phase, the enclosure (2) is isolated and the enclosures are placed in communication (EC ) and (1) to cause exothermic synthesis in (1), the heat formed being absorbed by the enclosure (2); in a third phase, connects the three enclosures and brings heat energy to the enclosure (1) to cause the exothermic decomposition steps in (1) and in
- the three enclosures are isolated from one another and placed at room temperature, said enclosures containing SEC + G, SI and S2 respectively;
- the enclosures (EC) and (2) are placed in communication, the enclosure (1) remaining isolated, to cause the exothermic synthesis in (2) and the production of cold in the enclosure (EC) at the equilibrium temperature in (EC) corresponding to the pressure in the assembly formed by (2) and (EC);
- the cold production cycle is thus complete.
- the reversible phenomenon in reactors (1) and (2) can be a reversible sorption chosen from reversible chemical reactions between gas G and a solid, adsorptions of gas G on a solid, and absorptions of gas G by a liquid .
- the reversible phenomenon in the device (EC) can be a sorption as defined above or a change in the liquid / gas phase of the gas G. Changes in the liquid / gas phase are preferred, since they make it possible to produce cold with a higher speed than with sorptions, due to the lower thermal inertia of the system.
- ammonia NH 3
- H 2 hydrogen
- carbon dioxide hydrogen
- the method according to the present invention can be implemented using an installation which comprises an endothermic element constituted by a device (EC) and an exothermic element constituted by a reactor (1) and a reactor (2).
- Said installation is characterized in that: the reactors (1) and (2) are in thermal contact, so that each of them constitutes an active thermal mass for the other; the reactors (1) and (2) and the device (EC) are provided with means making it possible to selectively put them in communication; the reactor (1) and the reactor (2) are provided with heating means (6) and means (5) for removing the heat; - at the start of the cycle
- the reactors (1) and (2) respectively contain a sorbent SI and a sorbent S2 capable of participating in a reversible sorption involving a gas G, the equilibrium curve of the reversible sorption in (1) being located in a temperature range higher than that of the equilibrium curve of the reversible sorption in (2) in the Clapeyron diagram;
- the device (EC) contains a compound G capable of undergoing a change of liquid / gas phase or a SEC + G sorbent rich in G gas capable of participating in a reversible sorption whose equilibrium temperature is lower than the temperature balance of reversible sorption in the reactor (2).
- the thermal contact between the reactors (1) and (2) is achieved by placing the reactor (1) inside the reactor (2).
- the reactors (1) and (2) can be concentric, the reactor (1) being placed inside the reactor (2).
- each of the reactors (1) and (2) consists of several hollow plates containing the respective sorbents, the plates of one being alternated with the plates of the other.
- the thickness of the plates is typically of the order of 1 to 3 cm.
- the production of cold takes place at the level of the device (EC). If the cold is intended for the production of ice cubes or cold water, the installation also includes a tank (3) containing water in direct thermal contact with the device.
- FIG. 1 represents a diagram of an installation according to the invention.
- the installation comprises a reactor (1) provided with heating means ( ⁇ ), a reactor (2) in thermal contact with the reactor (1) and provided with cooling means (5), a device (EC ), pipes fitted with valves VI and V2 for putting the reactors (1) and (2) selectively in contact with (EC).
- the reactor (1) contains a sorbent SI capable of forming a sorption with a gas G.
- the reactor (2) contains a sorbent S2 capable of forming a sorption with the gas G, the equilibrium temperature of SI being higher than the temperature of equilibrium of S2 at a given pressure.
- the device (EC) contains the gas G in the liquid state or a sorbent SEC capable of forming a sorption with the gas G, the equilibrium temperature of SEC being lower than the equilibrium temperature of S2 at a pressure given.
- the device (EC) is advantageously an evaporator / condenser (hereinafter referred to as an evaporator) seat of a change of liquid / gas phase
- (L / G). (EC) is in direct thermal contact with a reservoir (3) integrated in its wall and containing water.
- the installation and the method according to the invention are particularly advantageous when the device (2) is an evaporator / condenser (hereinafter referred to as an evaporator).
- the evaporator has a structure as shown in Figures 2 and 3.
- Figure 2 shows a cross-sectional view
- Figure 3 shows a longitudinal sectional view.
- the evaporator consists of a cylinder (8) which is closed at both ends and which has a circular section.
- the circular section has at its upper part a concave arc of a circle corresponding to the section of the ice cube tray (7).
- Hollow fins (9) are placed inside the evaporator, in the longitudinal direction.
- a tube (10) connected to the pipe allowing the transfer of the gas G between the evaporator and the reactors (1) or (2) penetrates into the cylindrical enclosure of the evaporator by a bore made in one of the ends of the cylinder, and it is placed directly under the wall of the ice cube tray (7).
- the working gas G in the form of a boiling liquid is placed at the bottom of the evaporator.
- the space between the walls of the fins is occupied by the phase change material M.
- the external wall of the evaporator (8) is made of a material having a high thermal diffusivity, that is to say a low capacity thermal to allow a rapid fall in the wall temperature and a high thermal conductivity to allow rapid formation of ice cubes.
- An aluminum-based material for example, which has low thermal capacity and high conductivity, is suitable because of its compatibility with ammonia, which is a gas frequently used in installations for producing cold at temperatures negative.
- the fins (9) increase the diffusion of heat from the boiling liquid to the ice cube tray, as well as the mechanical resistance of the evaporator.
- the ice cube tray 7 is provided with multiple transverse partitions, placed so as to obtain the desired shape for the ice cubes.
- the overall shape of the ice cube tray has a suitable geometry in a toroidal half-moon, which allows easy demolding of the ice cubes formed.
- phase change material M placed between the walls of the hollow fins maintains the temperature of the evaporator at a low temperature, which makes it possible to prolong the phase of ice production during the transient heating phase for the regeneration of the isolated reactor of 1 evaporator.
- the particular configuration of the tube (10) and its position in the enclosure of the evaporator are such that the hot gases, coming from the reactor during the phase 5 of placing the high pressure reactor in communication with the evaporator maintained at low pressure by the phase change material, first hit the wall of the ice cube tray, which facilitates detachment of the ice cubes.
- the method according to the invention for producing cold is implemented using an installation as described above, in which the enclosure (EC) also contains a material with solid / liquid phase change M.
- the material with phase change M is chosen so that the solidification temperature is at least slightly lower than the cold production temperature in (EC) corresponding to the synthesis in ( 2).
- a temperature difference of a few degrees, for example from 1 ° C to 10 ° C is suitable. For example, this temperature is 0 ° C when the goal is to make ice cubes.
- the material M can be chosen, for example, from paraffins such as n-alkanes having from 10 to 20 carbon atoms, eutectic mixtures and eutectic solutions.
- the curves on the diagrams correspond to monovariant phenomena.
- the operation of the installation would however be identical if a divariant phenomenon was used in the reactors (1) and / or (2), corresponding for example to the absorption of gas G by an absorbent solution (for example water / NH 3 , water / LiBr) or on the adsorption of gas G on the surface of an active solid (for example activated carbon or zeolite).
- Initial phase During an initial phase, the elements (1), (2) and (EC) are placed at ambient temperature T 0 and they are isolated from each other while keeping the valves VI and V2 closed. The elements being isolated from each other, they are at their respective equilibrium pressure at T 0 , designated by PE °, Pl ° and P2 °.
- (1) and (2) contain Si and S2 respectively.
- (EC) contains G in liquid form. SI, S2 and G are chosen so that Pl ° ⁇ P2 ° ⁇ PE °. The situation of the elements is represented by 1 °, 2 ° and E ° on the diagram of figure 4.
- Phase 1 First cold production phase
- valve V x remains closed.
- the evaporator (EC) goes from position E ° to E 1 and the reactor (2) from position 2 ° to 2 1 .
- the evolution of the respective positions is shown in FIG. 4.
- state 2 1 the reactor (2) is in the synthesis position, while in state E 1 , the evaporator (EC) is in state d 'evaporation.
- the communication between (EC) and (2) causes a sudden drop in temperature in (EC) and the temperature goes from T 0 to T E ⁇ . This drop in temperature thus initially allows the rapid freezing of the water contained in a tank (not shown in FIG.
- Phase 2 Second cold production phase
- phase 1 Cold is produced in one evaporator (EC) in E 2 , that is to say at a temperature T E2 lower than the cold production temperature T E ⁇ in phase 1. Because phases 1 and 2 are carried out one after the other, they give strong powers of cold production to T E2 , causing (EC) only from level T E 1 to T E 2 .
- the reactor (2) plays the role of thermal capacity for the reactor (1).
- the reactor (2) which absorbs the exothermic heat of reaction from the reactor (1), rises in temperature and is placed on its thermodynamic equilibrium in 2 2 . Thanks to this thermal capacity, the reactor (1) remains in l 2 which is a position far from its thermodynamic equilibrium, which allows a second peak of high production of cooling power.
- Phase 3 phase of ice removal and regeneration
- Elements (1), (2) and (EC) are quickly placed in positions l 3 , 2 3 and C 3 at a pressure level intermediate between that of phases 1 and 2.
- the content of the reactor (2) is decomposition position and the contents of the reactor (1) remain in the synthesis position.
- the differences "" in equilibrium of these synthesis / decomposition remain significant, because of the thermal contact which exists between the reactors (1) and (2).
- the decomposition in the reactor (2) is faster than the synthesis which ends in the reactor (1).
- a condensation is immediately engaged in the device (EC) which quickly evolves towards position C 3 . This exothermic condensation is possible because the heat is absorbed by the surface fusion of the ice cubes, which induces their detachment thus facilitating their subsequent evacuation from the device (EC).
- the temperature i 4 is the regeneration temperature (Treg) and the device (EC) is in position C 4 , which drives the reactor (2) in position 2 4 also at the pressure level imposed by the condensation.
- thermodynamic position C 4 is then necessarily such that the temperature corresponding to the position C 4 is higher than the ambient temperature To, this due to the transfer of condensation heat to the heat sink.
- the regeneration of the device implies that the extraction of heat from this exothermic condensation must take place in a heat sink, which may be the ambient air or a cooling circuit.
- the evolution of the position of the different elements is shown in Figure 6.
- Phase 4 Cooling phase and return to the initial phase
- the enclosure (EC) also contains a phase change material M whose temperature re phase change T M is at least slightly lower than the cold production temperature T E ⁇ in (EC) corresponding to the synthesis in (2)
- the regeneration of the sorbents contained in the reactors (1) and (2) is faster.
- the successive states in which the reactors (1) and (2) and the enclosure (EC) are found during the successive phases are shown on the Clausius-Clapeyron diagram represented in FIG. 8.
- the device (EC) can have the configuration shown in Figures 2 and 3.
- Phase 1 Phase of first production of cold
- valve Vi remains closed.
- the evaporator (EC) goes from position E ° to E 1 and the reactor (2) from position 2 ° to 2 1 .
- the reactor (2) In the state 2 1 , the reactor (2) is in the synthesis position, while in the state E 1 , the evaporator (EC) is in the evaporation state.
- phase change material in (EC) does not modify the course of phase 2.
- the reactors (1) and (2) and the enclosure (EC) are in the respective positions l 2 , 2 2 , E 2 .
- Phase 3 phase of ice removal and regeneration At the end of phase 2, the valve V 2 is opened, the valve Vi remaining open.
- Elements (1), (2) and (EC) are quickly placed in positions l 3 , 2 3 and C 3 at a pressure level intermediate between that of phases 1 and 2.
- the content of the reactor (2) is decomposition position and the contents of the reactor (1) remain in the synthesis position.
- the differences in equilibrium of these synthesis / decomposition remain significant, because of the thermal contact which exists between the reactors (1) and (2).
- the decomposition in the reactor (2) is faster than the synthesis which ends in the reactor (1).
- a condensation is immediately engaged in the device (EC) which quickly evolves towards position C 3 .
- This exothermic condensation is possible because the heat is absorbed by the surface fusion of the ice cubes, which induces their detachment thus facilitating their subsequent evacuation from the device (EC).
- the temperature Ti 4 ' is the regeneration temperature (Treg) and the device (EC) is in position C 4' , which causes the reactor (2) in position 2 4 'also at this pressure level imposed by the condensation of gas G.
- the opening of the valve V 2 , the valve Vi remaining open, and the switching on of the heating means (6) in the reactor (1) triggers the rapid desorption in the reactor (2) and the separation and evacuation of the ice cubes, the end of the synthesis in the reactor (1) followed by the desorption in (1).
- the condensation temperature imposed on the temperature T M by the fusion of the eutectic makes it possible on the one hand to carry out the condensation of the gas G at a temperature lower than the ambient temperature which makes it possible to clearly decrease the thermal amplitude traversed by the device (EC) implying a better efficiency of the process and shorter cycle times.
- the condensation pressure P c > is lower than the pressure P c obtained in the case without phase change material, which results in a decrease in the regeneration temperature of (1), and consequently of that of (2), which implies a reduction in the energy consumed for the regeneration of (1) and (2) again leading to a better efficiency of the process and a reduction in cycle times.
- Phase 4 Cooling phase and return to the initial phase The return to temperature T 0 takes place, for the entire installation, in a shorter time in the presence of a phase change material, causes the reactor (1) to be at a lower temperature.
- the installation according to the invention in its most general configuration, managed by the method of the invention, thus makes it possible to produce high-power cold over very short durations, which can allow the almost instantaneous production of ice cubes for example .
- the installation contains a phase change material in the endothermic element, the regeneration temperature in the reactor operating at the highest temperature is reduced, which on the one hand shortens the duration of the process and decreases energy consumption.
