FR 3 065 065 - A1 _ Procédé de régulation de la température de flux de fluides au moyen d'un dispositif de régulation comprenant un réservoir (2) contenant un bain de fluide (3) liquéfié ayant une température de liquéfaction déterminée, un premier circuit de fluide muni d'un premier échangeur (4) immergé dans le bain de fluide (3), un second circuit de fluide muni d'un second échangeur (5) immergé dans le bain de fluide (3), le procédé étant caractérisé en ce qu'un premier fluide à refroidir ayant une température supérieure à la température du fluide du bain est mis en circulation dans le premier circuit de fluide et dans le premier échangeur (4) immergé et en ce que, simultanément, un second fluide à réchauffer ayant une température inférieure à la température du fluide du bain est mis en circulation dans le second circuit de fluide et dans le second échangeur (5) immergé.FR 3 065 065 - A1 _ Method for regulating the temperature of fluid flows by means of a regulating device comprising a reservoir (2) containing a bath of liquefied fluid (3) having a determined liquefaction temperature, a first circuit of fluid provided with a first exchanger (4) immersed in the fluid bath (3), a second fluid circuit provided with a second exchanger (5) immersed in the fluid bath (3), the method being characterized in a first fluid to be cooled having a temperature higher than the temperature of the bath fluid is circulated in the first fluid circuit and in the first immersed exchanger (4) and in that, simultaneously, a second fluid to be heated having a temperature below the temperature of the bath fluid is circulated in the second fluid circuit and in the second immersed exchanger (5).
L’invention concerne un procédé de régulation de la température de flux de fluides.The invention relates to a method for regulating the temperature of fluid flow.
L’invention concerne en particulier un procédé de régulation de la température de fluide cryogénique (gaz ou liquide à une température inférieure ou égale à 150Kou -123°C).The invention relates in particular to a method for regulating the temperature of cryogenic fluid (gas or liquid at a temperature less than or equal to 150K or -123 ° C).
L’invention concerne plus particulièrement un procédé de régulation de la température de flux de fluides au moyen d’un dispositif de régulation comprenant un réservoir contenant un bain de fluide liquéfié ayant une température de liquéfaction déterminée, un premier circuit de fluide muni d’un premier échangeur immergé dans le bain de fluide, un second circuit de fluide muni d’un second échangeur immergé dans le bain de fluide.The invention relates more particularly to a method for regulating the temperature of fluid flows by means of a regulating device comprising a reservoir containing a bath of liquefied fluid having a determined liquefaction temperature, a first fluid circuit provided with a first exchanger immersed in the fluid bath, a second fluid circuit provided with a second exchanger immersed in the fluid bath.
Les échangeurs de chaleur multiphasiques existent sous des formes très diverses (vapo-condenseur de colonne à distiller, condenseur, évaporateur...).Multiphase heat exchangers exist in very diverse forms (distillation column vapor condenser, condenser, evaporator, etc.).
Dans le cas où plusieurs flux de fluides doivent être régulés thermiquement cela nécessite de multiples organes d’échange thermique (refroidissement,, surchauffe, vaporisation, condensation par exemple) dont il faut maîtriser l’inertie thermique.In the case where several fluid flows must be thermally regulated, this requires multiple heat exchange members (cooling, overheating, vaporization, condensation for example), the thermal inertia of which must be controlled.
Un but de la présente invention est de pallier tout ou partie des inconvénients de l’art antérieur relevés ci-dessus.An object of the present invention is to overcome all or part of the drawbacks of the prior art noted above.
A cette fin, le procédé selon l'invention, par ailleurs conforme à la définition générique qu’en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu’un premier fluide à refroidir ayant une température supérieure à la température du fluide du bain est mis en circulation dans le premier circuit de fluide et dans le premier échangeur immergé et en ce que, simultanément, un second fluide à réchauffer ayant une température inférieure à la température du fluide du bain est mis en circulation dans le second circuit de fluide et dans le second échangeur immergé.To this end, the method according to the invention, furthermore in accordance with the generic definition given in the preamble above, is essentially characterized in that a first fluid to be cooled having a temperature higher than the temperature of the fluid of the bath is circulated in the first fluid circuit and in the first submerged exchanger and in that, simultaneously, a second fluid to be heated having a temperature below the temperature of the fluid in the bath is circulated in the second fluid circuit and in the second submerged exchanger.
Par ailleurs, des modes de réalisation de l’invention peuvent comporter l'une ou plusieurs des caractéristiques suivantes :Furthermore, embodiments of the invention may include one or more of the following characteristics:

D’autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence aux figures dans lesquelles :Other particularities and advantages will appear on reading the description below, made with reference to the figures in which:
-la figure 1 représente une vue en coupe, schématique et partielle, illustrant la structure et le fonctionnement d’un exemple de dispositif régulation de la température de plusieurs flux de fluides,FIG. 1 represents a sectional view, schematic and partial, illustrating the structure and the operation of an example of a device for regulating the temperature of several fluids flows,
- la figure 2 représente une vue en coupe, schématique et partielle, illustrant une variante de réalisation d’un autre exemple du dispositif régulation.- Figure 2 shows a sectional view, schematic and partial, illustrating an alternative embodiment of another example of the regulation device.
Le dispositif 1 de régulation illustré à la figure comprend un système de stockage 2 (réservoir par exemple). Ce système de stockage contient un bain de fluide 3 liquéfié ayant une température de liquéfaction déterminée.The regulation device 1 illustrated in the figure comprises a storage system 2 (tank for example). This storage system contains a bath of liquefied fluid 3 having a determined liquefaction temperature.
Le bain de fluide 3 peut comprendre un fluide à à une température approchant son point triple par exemple. Par exemple le bain contient de l’azote liquide à ses conditions de saturation. Bien entendu, tout autre fluide approprié pourrait être utilisé pour ce bain selon les conditions de régulation nécessaires.The fluid bath 3 can comprise a fluid at a temperature approaching its triple point for example. For example, the bath contains liquid nitrogen at its saturation conditions. Of course, any other suitable fluid could be used for this bath according to the necessary regulation conditions.
Le dispositif 1 comprend un premier circuit de fluide qui transite dans le réservoir 2. Ce premier circuit est muni d’un premier échangeur 4 immergé dans le bain de fluide 3.The device 1 comprises a first fluid circuit which passes through the reservoir 2. This first circuit is provided with a first exchanger 4 immersed in the fluid bath 3.
Le premier circuit de fluide comprend par exemple une entrée dans le réservoir 2 au niveau d’une première extrémité du réservoir 2, par au niveau de l’extrémité supérieure du réservoir 2. Après avoir échangé thermiquement dans le bain 3, le premier circuit sort du réservoir 2 via une sortie au niveau d’une seconde extrémité du réservoir 2, par exemple inférieure. Bien entendu, la position des interfaces entrées et sorties de chaque circuit peut être quelconque dans le réservoir 2.The first fluid circuit comprises for example an inlet into the reservoir 2 at a first end of the reservoir 2, through at the level of the upper end of the reservoir 2. After having heat exchanged in the bath 3, the first circuit leaves of the reservoir 2 via an outlet at a second end of the reservoir 2, for example lower. Of course, the position of the input and output interfaces of each circuit can be arbitrary in the tank 2.
Un second circuit de fluide transite également dans le réservoir 2. Ce second circuit est muni d’un second échangeur 5 immergé dans le bain de fluideA second fluid circuit also passes through the reservoir 2. This second circuit is provided with a second exchanger 5 immersed in the fluid bath
3. Le second circuit de fluide transite dans le réservoir 2 via une entrée au niveau d’une extrémité du réservoir 2, par exemple inférieure, et en sort via une sortie située au niveau d’une autre extrémité du réservoir 2, par exemple supérieure, ou en sort au niveau de la même extrémité (cf. la variante de réalisation selon la figure 2).3. The second fluid circuit passes through the reservoir 2 via an inlet at one end of the reservoir 2, for example lower, and leaves it via an outlet situated at another end of the reservoir 2, for example upper , or leaves it at the same end (cf. the variant embodiment according to FIG. 2).
Selon une particularité, ce même dispositif sert simultanément au refroidissement et au réchauffage de deux flux de fluide ayant des températures distinctes. Ces deux flux peuvent être constitués du même fluide (gaz pur ou mélange, ou liquide pour partie par exemple) ou de deux fluides différents.According to a particular feature, this same device is used simultaneously for cooling and reheating two fluid flows having different temperatures. These two flows can be made up of the same fluid (pure gas or mixture, or partly liquid for example) or of two different fluids.
Dans le cas où les transits des deux fluides dans le bain sont orientés de façon opposée (l’un du haut vers le bas et l’autre du bas vers le haut), les refroidissements et réchauffements des deux fluides peuvent être réalisés de façon optimale et peuvent permettre d’homogénéiser les transferts thermiques dans le bain 3, en limitant le gradient thermique (initialement faible) dans le réservoir 2.In the case where the transits of the two fluids in the bath are oriented in opposite directions (one from the top to the bottom and the other from the bottom to the top), the cooling and heating of the two fluids can be carried out optimally and can make it possible to homogenize the heat transfers in the bath 3, by limiting the thermal gradient (initially low) in the tank 2.
Plus particulièrement, un premier fluide à refroidir ayant une température supérieure à la température du fluide du bain 3 est mis en circulation dans le premier circuit de fluide et dans le premier échangeur 4 immergé tandis que, simultanément, un second fluide à réchauffer ayant une température inférieure à la température du fluide du bain est mis en circulation dans le second circuit de fluide et dans le second échangeur 5 immergé.More particularly, a first fluid to be cooled having a temperature higher than the temperature of the fluid in the bath 3 is circulated in the first fluid circuit and in the first immersed exchanger 4 while, simultaneously, a second fluid to be heated having a temperature below the temperature of the bath fluid is circulated in the second fluid circuit and in the second submerged exchanger 5.
Ceci permet de resserrer les écarts de température entre deux circuits (un circuit de fluide relativement “froid” et un circuit de fluide relativement “chaud”). Ceci permet de limiter les pertes énergétiques entre les deux flux de fluides. Ceci permet une meilleure intégration thermique dans une installation en récupérant au mieux l’énergie de chaque fluide. Cette solution permet d’éviter la génération d’un écart de température fatal à l’entrée d’un échangeur de chaleur utilisant ces deux circuits (tel qu’un échangeur en aluminium par exemple).This makes it possible to narrow the temperature differences between two circuits (a relatively “cold” fluid circuit and a relatively “hot” fluid circuit). This makes it possible to limit the energy losses between the two flows of fluids. This allows better thermal integration in an installation by recovering the energy of each fluid as well as possible. This solution avoids the generation of a fatal temperature difference at the inlet of a heat exchanger using these two circuits (such as an aluminum exchanger for example).
Par exemple, le premier fluide mis en circulation dans le premier circuit de fluide et dans le premier échangeur 4 vaporise au moins en partie le fluide contenu dans le bain 3 tandis que le second fluide mis en circulation dans le second circuit de fluide et dans le second échangeur 5 condense au moins en partie le fluide contenu dans le bain 3.For example, the first fluid circulated in the first fluid circuit and in the first exchanger 4 at least partially vaporizes the fluid contained in the bath 3 while the second fluid circulated in the second fluid circuit and in the second exchanger 5 at least partially condenses the fluid contained in the bath 3.
Il peut donc y avoir couplage des transferts thermiques par condensation et vaporisation d’un même fluide (ou deux fluides distincts) dans un unique récipient. Par ailleurs, les fluides contenus dans les échangeurs thermiques 4 et 5, peuvent être des fluides distincts et peuvent également être sujets à des phénomènes de vaporisation ou de condensation en interne.There can therefore be coupling of heat transfers by condensation and vaporization of the same fluid (or two separate fluids) in a single container. Furthermore, the fluids contained in the heat exchangers 4 and 5 can be separate fluids and can also be subject to internal vaporization or condensation phenomena.
Cette configuration permet une économie du fluide du bain qui est mutualisé tout en bénéficiant de la grande inertie thermique d’un échangeur immergé et des faibles pincements de température atteignables.This configuration allows economy of the bath fluid which is shared while benefiting from the great thermal inertia of a submerged exchanger and the low temperature pinches achievable.
En effet, deux types de transfert thermique ont lieu dans ce bain : un refroidissement d’un fluide relativement plus chaud grâce à l’échange thermique avec un bain de liquide (de préférence à saturation) et, dans le même temps, un réchauffement d’un fluide relativement plus froid que le liquide du bain via un canal parallèle d’échange thermique.In fact, two types of thermal transfer take place in this bath: a cooling of a relatively hotter fluid thanks to the heat exchange with a liquid bath (preferably at saturation) and, at the same time, a heating of 'a relatively cooler fluid than the bath liquid via a parallel heat exchange channel.
Comme illustré, les premier 4 et/ou second 5 échangeurs immergé ont par exemple une structure en serpentin.As illustrated, the first 4 and / or second 5 submerged exchangers have for example a serpentine structure.
De plus, échangeurs 4, 5 peuvent être imbriqués au moins en partie l’un dans l’autre et/ou disposés de façon concentrique dans le bain.In addition, exchangers 4, 5 can be at least partially nested one inside the other and / or arranged concentrically in the bath.
Le liquide du bain peut être de l’azote ou tout autre fluide approprié.The bath liquid can be nitrogen or any other suitable fluid.
Le premier et second fluides peuvent comprendre tout ou partie parmi : du néon, de l’azote, de l’hélium, de l’hydrogène ou tout autre fluide ou mélange 10 approprié.The first and second fluids may include all or part of: neon, nitrogen, helium, hydrogen or any other suitable fluid or mixture.
