Description

DISPOSITIF MODULAIRE EXTERNE DE REGULATION AUTONOME DE LA TEMPERATURE D'UNE ENCEINTE  EXTERNAL MODULAR DEVICE FOR AUTONOMOUS REGULATION OF THE TEMPERATURE OF AN ENCLOSURE
La présente invention concerne un dispositif modulaire externe de régulation autonome de la température d'une enceinte constituée d'un container isotherme, du type notamment destiné au transport de marchandises thermosensibles. The present invention relates to an external modular device for autonomously regulating the temperature of an enclosure consisting of an isothermal container, of the type especially intended for the transport of thermosensitive goods.
On sait que pour sécuriser la chaîne du froid de ce type d'enceinte il ne suffit pas d'être en mesure de produire du froid, dans la mesure où, au cours de son transport, l'enceinte peut se trouver soumise à des conditions de basses températures nécessitant ainsi d'assurer son chauffage. Tel est par exemple le cas d'une enceinte renfermant des produits thermosensibles devant impérativement être conservés entre 2 et 8°C et qui, lors de son transport, se trouve soumise pendant une certaine période à une température extérieure de -10°C puis pendant une autre période à une température de 30°C etc ..  We know that to secure the cold chain of this type of enclosure it is not enough to be able to produce cold, to the extent that, during its transportation, the enclosure may be subject to conditions low temperatures thus requiring heating. This is for example the case of an enclosure containing thermosensitive products which must be kept between 2 and 8 ° C and which, during its transport, is subjected for a certain period to an external temperature of -10 ° C and then during another period at a temperature of 30 ° C etc.
Dans le cas où l'enceinte est constituée d'un container de fort volume, on fait habituellement appel à un groupe frigorifique dont l'évaporateur est en mesure de fournir à l'enceinte les frigories nécessaires à son refroidissement et qui est également en mesure de fournir à celle-ci les calories nécessaires à son chauffage, et ceci en faisant traverser le fluide compressé chaud dans l'évaporateur.  In the case where the enclosure consists of a container of high volume, it is usually used a refrigeration unit whose evaporator is able to provide the enclosure the frigories necessary for its cooling and which is also able to provide the latter with the calories necessary for its heating, and this by passing through the hot compressed fluid in the evaporator.
Un tel dispositif, notamment pour des raisons de poids et d'encombrement, n'est cependant utilisable que sur des enceintes de fort volume. Par ailleurs ce système doit être en mesure d'être relié en permanence à une source d'énergie électrique ce qui complique bien entendu la question de son transport. De plus, l'utilisation de l'évaporateur en tant que moyens de production de chaleur n'est possible que sur certains types de groupes frigorifiques. Enfin, de tels dispositifs ne peuvent fonctionner qu'en mode production de froid ou en mode production de chaud, si bien que le passage de l'un à l'autre mode présente le risque de créer un choc thermique susceptible de nuire à l'intégrité de certains produits thermosensibles. Par ailleurs ces dispositifs sont habituellement intégrés aux enceintes dont on souhaite maîtriser la température et constituent avec celles-ci un ensemble indissociable. Il est intéressant pourtant d'être en mesure de disposer d'un dispositif de régulation de la température qui puisse être disposé sur plusieurs types de containers, notamment par exemple afin de pouvoir assortir la puissance du dispositif de régulation à la puissance nécessitée par la nature des produits transportés et les conditions climatiques rencontrées au cours de ce transport. Such a device, especially for reasons of weight and bulk, however, can only be used on speakers of high volume. Moreover, this system must be able to be permanently connected to a source of electrical energy which complicates of course the question of its transport. In addition, the use of the evaporator as heat generating means is only possible on certain types of refrigeration units. Finally, such devices can only work in cold production mode or hot production mode, so that the transition from one to the other mode has the risk of creating a thermal shock that could harm the system. integrity of certain heat-sensitive products. Moreover, these devices are usually integrated speakers whose temperature is desired to control and together with them an indissociable set. It is interesting, however, to be able to have a temperature control device that can be arranged on several types of containers, including for example in order to match the power of the control device to the power required by nature transported products and climatic conditions encountered during this transport.
La présente invention a pour but de proposer un dispositif externe de maintien en température d'une enceinte qui puisse être monté, éventuellement de manière amovible sur une enceinte dont la température interne doit être conservée à une valeur de consigne donnée, qui soit totalement autonome du point de vue énergétique et qui soit en mesure d'assurer sa fonction de régulation quel que soit le profil de la température extérieure auquel l'enceinte est soumise ;ce dispositif étant de plus modulaire et adaptable sur l'enceinte à réguler.  The object of the present invention is to provide an external device for maintaining the temperature of an enclosure that can be mounted, possibly removably, on an enclosure whose internal temperature must be kept at a given reference value, which is completely independent of the From an energy point of view, it is able to perform its regulation function whatever the profile of the external temperature to which the chamber is subjected, this device being moreover modular and adaptable to the enclosure to be regulated.

Le dispositif suivant l'invention est conçu pour permettre de maintenir une enceinte contenant des produits thermosensibles à une température de consigne Tc déterminée pendant une période donnée, et ce quelques soient les conditions climatiques auxquelles cette dernière est soumise lors, par exemple, d'un transport. The device according to the invention is designed to make it possible to maintain an enclosure containing temperature-sensitive products at a set temperature T c determined during a given period, whatever the climatic conditions to which the latter is subjected when, for example, a transport.
On a représenté sur les figures 2 à 5 un exemple d'un container formant une enceinte 1 qui est destinée à contenir des produits thermosensibles 3 et qui reçoit en sa partie supérieure un dispositif 2 de régulation autonome de la température suivant l'invention.  There is shown in Figures 2 to 5 an example of a container forming an enclosure 1 which is intended to contain temperature-sensitive products 3 and which receives in its upper part a device 2 for autonomous regulation of the temperature according to the invention.
Ce dernier comprend un carter 22 (représenté en traits pointillés sur les figures 2 à 4) qui contient un système thermochimique, de type connu, qui peut être mis en œuvre avec des sels et des gaz divers et qui est essentiellement constitué d'un réacteur 9 contenant un produit réactif, constitué en l'espèce de chlorure de manganèse, qui est mélangé et compacté avec un liant expanseur notamment constitué de graphite naturel expansé, la masse volumique apparente de celui-ci étant préférentiellement comprise entre 50 kg/m3 et 150 kg/m3 et la proportion massique de chlorure de manganèse par rapport au graphite naturel expansé étant préférentiellement comprise entre 50% et 90%. The latter comprises a housing 22 (shown in broken lines in FIGS. 2 to 4) which contains a thermochemical system of known type which can be used with various salts and gases and which essentially consists of a reactor 9 containing a reactive product, consisting in this case of manganese chloride, which is mixed and compacted with an expanding binder including expanded natural graphite, the bulk density thereof being preferably between 50 kg / m 3 and 150 kg / m 3 and the mass proportion of chloride of manganese relative to the expanded natural graphite being preferably between 50% and 90%.
Les termes « masse volumique apparente du graphite naturel expansé » désignent la masse volumique calculée selon la formule suivante sur le produit final compacté : (masse du graphite naturel mélangé à une masse donnée du produit réactif pour obtenir le produit compacté)/ volume de l'élément obtenu par compactage du mélange de la masse de graphite naturel précitée avec la masse donnée de réactif précitée.  "Bulk density of expanded natural graphite" means the density calculated according to the following formula on the final compacted product: (mass of natural graphite mixed with a given mass of the reactive product to obtain the compacted product) / volume of the element obtained by compacting the mixture of the above-mentioned natural graphite mass with the given mass of aforementioned reagent.
Le réacteur 9 est en communication, sous le contrôle d'une vanne de commande 1 1 , avec un réservoir 13 dans lequel est stocké un gaz spécifique, constitué d'ammoniac, ce réservoir faisant office en l'espèce d'évaporateur.  The reactor 9 is in communication, under the control of a control valve 1 1, with a tank 13 in which is stored a specific gas, consisting of ammonia, this tank acting as an evaporator.
Le produit réactif et le gaz sont tels que le produit réactif est apte, par une réaction thermochimique exothermique, lors d'une phase dite de fonctionnement, à absorber le gaz, générant ainsi un produit de réaction, et à le restituer ensuite, par une réaction thermochimique inverse, lors d'une phase dite de régénération, lorsque l'on chauffe le produit de réaction.  The reactive product and the gas are such that the reactive product is capable, by an exothermic thermochemical reaction, during a so-called operating phase, of absorbing the gas, thus generating a reaction product, and then returning it, by a inverse thermochemical reaction, during a so-called regeneration phase, when the reaction product is heated.
Ainsi, lorsque le réacteur 9 et l'évaporateur 13 sont mis en communication, le gaz liquide contenu dans ce dernier se vaporise, ce qui absorbe une certaine quantité de chaleur, si bien qu'il est la source d'une production de froid, et ce gaz est absorbé par le matériau réactif, générant ainsi une réaction chimique exothermique, si bien que le réacteur est la source d'une production de chaleur. Une fois la réaction terminée, lorsque l'on réchauffe le produit de réaction contenu dans le réacteur 9, on libère le gaz absorbé par le matériau réactif et celui-ci se condense alors dans l'évaporateur 13.  Thus, when the reactor 9 and the evaporator 13 are placed in communication, the liquid gas contained in the latter vaporizes, which absorbs a certain amount of heat, so that it is the source of a production of cold, and this gas is absorbed by the reactive material, thereby generating an exothermic chemical reaction, so that the reactor is the source of heat generation. Once the reaction is complete, when the reaction product contained in the reactor 9 is heated, the absorbed gas is released by the reactive material and the latter then condenses in the evaporator 13.
Suivant l'invention, et ainsi que représenté sur les figures, le réacteur 9 et l'évaporateur 13 sont respectivement disposés dans des compartiments séparés 10 et 14 dont les entrées respectives 10a et 14a peuvent être mises en communication avec un conduit d'entrée 5 en communication avec une sortie 5a de l'enceinte 1 , et les sorties 10b et 14b peuvent être mises en communication avec un conduit de sortie 7 également en communication avec une entrée 7a de l'enceinte 1 et ceci sous le contrôle d'un système de six clapets de distribution qui sont asservis entre eux sous la commande d'un microcontrôleur, non représenté sur le dessin et ainsi qu'expliqué ci-après. According to the invention, and as shown in the figures, the reactor 9 and the evaporator 13 are respectively disposed in separate compartments 10 and 14 whose respective inlets 10a and 14a can be placed in communication with an inlet duct 5 in communication with an output 5a of the enclosure 1, and the outputs 10b and 14b can be placed in communication with an outlet conduit 7 also in communication with an input 7a of the enclosure 1 and this under the control of a system six distribution valves which are slaved to each other under the control of a microcontroller, not shown in the drawing and as explained below.
Sur les figures ci-jointes, une extrémité du conduit d'entrée 5 est apte à être connectée aux entrées 10a et 14a précitées, la deuxième extrémité du conduit d'entrée 5 est connectée avec la sortie 5a ménagée dans enceinte 1 . De même, une extrémité du conduit de sortie 7 est apte à être connectée aux sorties 10b et 14b précitées tandis que l'autre extrémité du conduit de sortie 7 est connectée à une sortie 7a ménagée dans l'enceinte 1 .  In the accompanying figures, one end of the inlet duct 5 is capable of being connected to the aforementioned inlets 10a and 14a, the second end of the inlet duct 5 is connected with the outlet 5a formed in enclosure 1. Similarly, one end of the outlet duct 7 is capable of being connected to the above-mentioned outlets 10b and 14b while the other end of the outlet duct 7 is connected to an outlet 7a formed in the enclosure 1.
Le compartiment réacteur 10 comporte des moyens de ventilation 12 qui assurent la circulation de l'air de son entrée 10a vers sa sortie 10b et propulse cet air, via le conduit de sortie 7, dans l'enceinte 1 . De même, le compartiment évaporateur 14 comporte des moyens de ventilation 16 qui assurent la circulation de l'air de son entrée 14a vers sa sortie 14b et propulse cet air, via le conduit de sortie 7, dans l'enceinte 1 .  The reactor compartment 10 comprises ventilation means 12 which ensure the circulation of air from its inlet 10a to its outlet 10b and propels this air, via the outlet duct 7, into the enclosure 1. Similarly, the evaporator compartment 14 comprises ventilation means 16 which ensure the circulation of air from its inlet 14a to its outlet 14b and propels this air, via the outlet duct 7, into the chamber 1.
Le compartiment réacteur 9 comporte un clapet d'entrée 17a et un clapet de sortie 17b qui sont aptes à occuper chacun une position ouverte dans laquelle le compartiment réacteur 10 est en communication avec l'extérieur (figure 2) et une position fermée dans laquelle il est isolé de l'extérieur (figure 3).  The reactor compartment 9 comprises an inlet valve 17a and an outlet valve 17b which are each able to occupy an open position in which the reactor compartment 10 is in communication with the outside (FIG. 2) and a closed position in which it is isolated from the outside (Figure 3).
De même, le compartiment évaporateur 14 comporte un clapet d'entrée Similarly, the evaporator compartment 14 comprises an inlet valve
19a et un clapet de sortie 19b qui sont aptes à occuper chacun une position ouverte dans laquelle le compartiment évaporateur est en communication avec l'extérieur (figure 3) et une position fermée dans laquelle il est isolé de l'extérieur (figure 2). 19a and an outlet valve 19b which are each adapted to occupy an open position in which the evaporator compartment is in communication with the outside (Figure 3) and a closed position in which it is isolated from the outside (Figure 2).
Le système comprend également deux clapets inverseurs, à savoir un clapet 21 a en entrée et un clapet 21 b en sortie qui sont en mesure d'occuper trois positions, à savoir :  The system also comprises two reversing valves, namely a valve 21a input and a valve 21b output that are able to occupy three positions, namely:
une première position, représentée sur la figure 2, dans laquelle ils mettent respectivement l'entrée et la sortie de l'évaporateur 13 en communication avec l'enceinte 1 ,  a first position, represented in FIG. 2, in which they respectively put the inlet and the outlet of the evaporator 13 in communication with the enclosure 1,
une seconde position, représentée sur la figure 3, dans laquelle ils mettent respectivement l'entrée et la sortie du réacteur 9 en communication avec l'enceinte 1 , une troisième position, représentée sur la figure 4, dans laquelle les clapets sont en position médiane et mettent respectivement l'entrée et la sortie du réacteur 9 et de l'évaporateur 13 en communication avec l'enceinte 1 . a second position, shown in FIG. 3, in which they respectively put the inlet and the outlet of the reactor 9 in communication with the enclosure 1, a third position, shown in Figure 4, wherein the valves are in the middle position and respectively the inlet and the outlet of the reactor 9 and the evaporator 13 in communication with the chamber 1.
Dans un exemple d'utilisation de la présente invention, on souhaite réaliser le transport international d'un produit 3 contenu dans l'enceinte 1 qui devra être maintenue à une température de consigne Tc de 5°C et qui sera soumise au cours de ce transport à divers aléas de température. In an example of use of the present invention, it is desired to carry out the international transport of a product 3 contained in the enclosure 1 which will have to be maintained at a set temperature T c of 5 ° C. and which will be submitted during this transport to various hazards of temperature.
Ainsi, dans le présent exemple, et ainsi que représenté sur la figure 1 , le container équipé du dispositif de régulation en température suivant l'invention est tout d'abord transporté de son entrepôt où la température est de 15°C (période 1 ) pour être chargé en soute d'un avion dans lequel la température descend rapidement et reste à environ -20°C pendant 10 heures (période 2). A l'arrivée le container est disposé en attente à l'extérieur pendant quatre heures à une température de 40°C (période 3), pour être ensuite transféré dans un hangar d'une zone de fret où il reste à 25°C pendant 5 heures (période 4). Il est ensuite chargé en soute d'un autre avion où sa température descend à -20°C pendant cinq heures (période 5) puis est transporté à une température extérieure de -30 (période 6) vers son lieu de réception.  Thus, in the present example, and as shown in Figure 1, the container equipped with the temperature control device according to the invention is first transported from its warehouse where the temperature is 15 ° C (period 1) to be loaded in the hold of an aircraft in which the temperature drops rapidly and remains at about -20 ° C for 10 hours (period 2). On arrival the container is placed on standby outside for four hours at a temperature of 40 ° C (period 3), then transferred to a shed of a cargo area where it remains at 25 ° C for 5 hours (period 4). It is then loaded in the hold of another aircraft where its temperature drops to -20 ° C for five hours (period 5) and is then transported to an outside temperature of -30 (period 6) to its place of reception.
Dans ces conditions on comprend que pendant les périodes 1 , 3 et 4 il est nécessaire de refroidir l'enceinte 1 , et le microcontrôleur qui pilote les clapets de commutation les positionne dans la position représentée sur la figure 2, c'est-à-dire que d'une part les clapets inverseurs 21 a et 21 b dégagent l'entrée 14a et la sortie 14b du compartiment 14 contenant l'évaporateur 13 et, d'autre part, les clapets 19a et 19b sont en position d'ouverture de façon à mettre l'évaporateur en communication avec l'enceinte 1 afin de refroidir celle-ci et, dans le même temps, les clapets 17a et 17b sont ouverts afin de mettre en communication avec l'extérieur l'entrée 10a et la sortie 10b du compartiment 10 afin d'évacuer dans l'atmosphère la chaleur produite par le réacteur 9 au cours de la réaction thermochimique.  Under these conditions it is understood that during periods 1, 3 and 4 it is necessary to cool the chamber 1, and the microcontroller which controls the switching valves positions them in the position shown in Figure 2, that is to say say that on the one hand the reversing valves 21a and 21b clear the inlet 14a and the outlet 14b of the compartment 14 containing the evaporator 13 and, on the other hand, the valves 19a and 19b are in the open position of way to put the evaporator in communication with the enclosure 1 to cool it and, at the same time, the valves 17a and 17b are open to communicate with the outside the inlet 10a and the outlet 10b compartment 10 to vent the heat generated by the reactor 9 during the thermochemical reaction.
Inversement, au cours des périodes 2, 5, et 6 l'enceinte 1 devra être réchauffée et, pour ce faire, les clapets sont positionnés dans la position représentée sur la figure 3, c'est-à-dire que d'une part les clapets inverseurs 21 a et 21 b dégagent l'entrée 10a et la sortie 10b du compartiment 10 contenant le réacteur 9 et d'autre part les clapets 17a et 17b sont en position de fermeture vis-à-vis de l'extérieur, de façon à mettre le compartiment 10 contenant le réacteur 9 en communication avec l'enceinte 1 afin de réchauffer celle-ci et, dans le même temps, les clapets 19a et 19b sont ouverts afin de mettre l'évaporateur 13 en communication avec l'extérieur afin d'évacuer dans l'atmosphère le froid généré par ce dernier. Conversely, during periods 2, 5, and 6, the chamber 1 will have to be reheated and, for this purpose, the valves are positioned in the position shown in FIG. 3, that is to say that on the one hand reversing valves 21a and 21b clear the inlet 10a and the outlet 10b of the compartment 10 containing the reactor 9 and on the other hand the valves 17a and 17b are in the closed position vis-à-vis the outside, so as to put the compartment 10 containing the reactor 9 in communication with the enclosure 1 in order to heat the latter and, at the same time, the valves 19a and 19b are open in order to put the evaporator 13 in communication with the outside in order to evacuate to the atmosphere the cold generated by the latter.
Suivant l'invention, afin d'être en mesure de réguler finement la température dans l'enceinte lorsque la température extérieure oscille autour de la température de consigne Te de l'enceinte 1 , on positionne les clapets, ainsi que représenté sur la figure 4, dans une position où l'on envoie simultanément dans l'enceinte 1 de l'air chaud et de l'air froid. Pour ce faire les clapets inverseurs 21 a et 21 b sont mis en position médiane et les clapets d'entrée 17a et 19a et les clapets de sortie 17b et 19b assurent la communication avec l'enceinte de l'entrée et de la sortie à la fois du réacteur et de l'évaporateur.  According to the invention, in order to be able to finely regulate the temperature in the chamber when the external temperature oscillates around the set temperature Te of the chamber 1, the valves are positioned, as shown in FIG. , in a position where it sends simultaneously in the chamber 1 of the hot air and cold air. To do this, the inverting valves 21a and 21b are placed in the median position and the inlet valves 17a and 19a and the outlet valves 17b and 19b provide communication with the enclosure of the inlet and the outlet at the inlet. reactor and evaporator.
On pourrait bien entendu suivant l'invention faire appel à tout autre mode de commutation que des clapets.  It may of course according to the invention to use any other switching mode that valves.
Ainsi que représenté sur les figures 2 à 5a, le dispositif de régulation suivant l'invention peut être fixé en partie supérieure de l'enceinte 1 . Cependant ainsi que représenté sur la figure 5b, il peut également être fixé en partie inférieure de celle-ci. Le carter 22 est donc soit monté sur l'enceinte 1 soit sous cette dernière.  As represented in FIGS. 2 to 5a, the regulation device according to the invention can be fixed at the top of the enclosure 1. However, as shown in FIG. 5b, it can also be fixed in the lower part thereof. The housing 22 is either mounted on the enclosure 1 or under the latter.
Dans un autre mode de mise en œuvre de l'invention le dispositif de régulation peut également être disposé entre deux enceintes 1 et 1 ', ce qui présente l'avantage d'être en mesure d'envoyer simultanément de l'air chaud dans l'une des enceintes (enceinte 1 ) et de l'air froid dans l'autre enceinte (enceinte 1 ').  In another embodiment of the invention, the regulating device can also be arranged between two enclosures 1 and 1 ', which has the advantage of being able to simultaneously send hot air into the chamber. one of the speakers (enclosure 1) and cold air in the other enclosure (enclosure 1 ').
