La présente invention concerne le domaine des échangeurs air /neige carbonique, et plus particulièrement une méthode de régulation de la puissance frigorifique d’un tel échangeur.The present invention relates to the field of air / dry ice exchangers, and more particularly to a method of regulating the cooling capacity of such an exchanger.
On trouve de tels échangeurs notamment dans le domaine du transport et de la distribution de produits thermosensibles, tels les produits pharmaceutiques et les denrées alimentaires. Dans ce domaine, le froid nécessaire au maintien de la température des produits est fourni principalement par deux technologies différentesSuch exchangers are found in particular in the field of transport and distribution of heat-sensitive products, such as pharmaceuticals and foodstuffs. In this area, the cold necessary to maintain the temperature of the products is provided mainly by two different technologies
- les groupes frigorifiques à compression mécanique de vapeur fonctionnant en boucle fermée ;- refrigeration units with mechanical vapor compression operating in a closed loop;
- les groupes cryogéniques fonctionnant en boucle ouverte et mettant en oeuvre une injection directe ou indirecte de fluides cryogéniques et en particulier d’azote liquide.- cryogenic groups operating in open loop and using direct or indirect injection of cryogenic fluids and in particular liquid nitrogen.
Et ainsi de tels échangeurs air/neige sont mis en oeuvre dans les solutions cryogéniques à injection indirecte où un fluide cryogénique alimentant la caisse du camion provient traditionnellement d’un réservoir cryogénique embarqué sous le camion, et est acheminé jusqu’à un ou plusieurs échangeurs thermiques situés à l’intérieur de la ou les chambres froides du camion, échangeurs munis de moyens de circulation d’air. Ces échangeurs permettent le refroidissement, à la température désirée, de l’air interne de la chambre stockant les produits.And thus such air / snow exchangers are used in cryogenic solutions with indirect injection where a cryogenic fluid supplying the truck body traditionally comes from a cryogenic tank embedded under the truck, and is conveyed to one or more exchangers thermals located inside the cold room (s) of the truck, heat exchangers provided with air circulation means. These exchangers allow the cooling of the internal air of the chamber storing the products to the desired temperature.
Rappelons que le contrôle de procédé typiquement mis en oeuvre dans de tels camions fonctionnant en injection indirecte est le suivant :Recall that the process control typically implemented in such trucks operating in indirect injection is as follows:
1- lors de la mise en route du système frigorifique du camion (par exemple au démarrage d’une tournée du camion ou après un arrêt prolongé du système frigorifique pour une raison quelconque) ou encore après une ouverture de porte, on adopte un mode de « descente rapide » en température (cette industrie nomme cette phase « pull down »).1- when starting the refrigeration system of the truck (for example at the start of a truck tour or after a prolonged stop of the refrigeration system for any reason) or even after a door opening, we adopt a mode of "Rapid descent" in temperature (this industry calls this phase "pull down").
2- Une fois la température de consigne atteinte dans la chambre de stockage des produits, on adopte un mode de contrôle/régulation qui permet de maintenir la température de la chambre de stockage des produits à la valeur de la consigne (cette industrie nomme cette phase « maintien » ou « régulation »).2- Once the set temperature is reached in the product storage chamber, a control / regulation mode is adopted which allows the temperature of the product storage chamber to be kept at the set value (this industry names this phase "Maintenance" or "regulation").
Les professionnels de ce secteur parlent également d’un fonctionnement en pleine charge (phase 1) ou à charge partielle (phase 2).Professionals in this sector also speak of full load (phase 1) or partial load (phase 2) operation.
Un exemple d’un tel échangeur air/neige carbonique est décrit dans le document FR-3 034 511, échangeur qui comporte au moins une plaque d’une mousse métallique ou d’une paille métallique, mousse ou paille se caractérisant par un taux de porosité ou de vide donné, plaque de mousse ou de paille qui est apte à stocker en son sein une quantité de CO2 liquide ou de neige carbonique, échangeur qui comporte également une plaque de contact, solidaire par une de ses deux faces de ladite plaque de mousse ou de paille, plaque de contact apte, au niveau de son autre face à être mise en contact avec l’air d’un espace à refroidir.An example of such an air / dry ice exchanger is described in the document FR-3,034,511, exchanger which comprises at least one plate of a metallic foam or a metallic straw, foam or straw characterized by a rate of porosity or given vacuum, foam or straw plate which is capable of storing within it a quantity of liquid CO 2 or carbon dioxide snow, exchanger which also comprises a contact plate, integral by one of its two faces with said plate foam or straw, suitable contact plate, at its other face to be brought into contact with the air of a space to be cooled.
Comme signalé ci-dessus, la présente invention s’intéresse plus particulièrement à une méthode de régulation de la diffusion de froid par un tel échangeur Air/Neige carbonique.As indicated above, the present invention relates more particularly to a method for regulating the diffusion of cold by such an Air / Carbon dioxide exchanger.
Comme on le verra plus en détail dans ce qui suit, l’invention propose d’utiliser un équipement de type « volet roulant », par exemple horizontal quand l’échangeur est positionné au plafond de la caisse interne du camion, volet permettant d’occulter tout ou partie de la surface de l’échangeur en contact avec l’air de l’espace à refroidir.As will be seen in more detail below, the invention proposes using equipment of the “rolling shutter” type, for example horizontal when the exchanger is positioned on the ceiling of the internal body of the truck, a shutter allowing obscure all or part of the surface of the exchanger in contact with the air in the space to be cooled.
Et selon un mode de réalisation tout particulièrement avantageux de réalisation de l’invention, le volet est muni d’un système de racloir permettant l’élimination (et le cas échéant également la collecte) du givre en formation sur ladite surface.And according to a particularly advantageous embodiment of the invention, the shutter is provided with a scraper system allowing the elimination (and if necessary also the collection) of the frost forming on said surface.
La figure 1 annexée illustre un mode de réalisation de l’invention.Figure 1 attached illustrates an embodiment of the invention.
La référence 1 désigne l’échangeur dans sa globalité, la plaque de contact étant le cas échéant munie d’ailettes (2) placées perpendiculairement à la face de la plaque qui est mise en contact avec l’espace à refroidir.Reference 1 designates the exchanger as a whole, the contact plate being if necessary provided with fins (2) placed perpendicular to the face of the plate which is brought into contact with the space to be cooled.
Et la référence 3 désigne le système de volet roulant qui, on le visualise bien sur la figure, peut se déployer le long de la face en question pour en obturer tout ou partie de la surface et ainsi réguler la surface froide en contact avec l’espace à refroidir et donc la quantité de froid transmise à cet espace.And reference 3 designates the roller shutter system which, as can be seen in the figure, can be deployed along the face in question to close off all or part of the surface and thus regulate the cold surface in contact with the space to be cooled and therefore the amount of cold transmitted to this space.
L’invention est tout particulièrement utile pour le transport de produits frais (maintenus typiquement entre +2°C et +8°C) pour lesquels un excès de fourniture de froid peut poser un grave problème de gel des produits et donc d’endommagement de ces produits.The invention is particularly useful for transporting fresh products (typically kept between + 2 ° C and + 8 ° C) for which an excess of cold supply can pose a serious problem of freezing of the products and therefore of damage to these products.
On adoptera alors préférentiellement un contrôle de la position du volet où :We will then preferentially adopt a control of the flap position where:
- en mode « descente rapide » ou « pull down » : le volet est totalement ouvert ;- in "rapid descent" or "pull down" mode: the shutter is fully open;
- en mode « régulation » ou « maintien » : ouverture du volet proportionnellement à la demande de froid ;- in "regulation" or "maintenance" mode: opening of the shutter in proportion to the cooling demand;
- en mode « sécurité » : volet totalement fermé, par exemple en cas d’ouverture de porte. Lorsque le livreur pénètre dans la caisse, le volet doit rapidement se refermer afin de limiter le risque de brûlure par contact sur la surface d’échange de l’échangeur.- in "security" mode: shutter completely closed, for example when the door is opened. When the delivery man enters the crate, the flap must close quickly to limit the risk of contact burns on the exchanger's exchange surface.
La figure 2 annexée illustre un exemple de logigramme de fonctionnement :FIG. 2 appended illustrates an example of an operating flow diagram:
Pvolet = position du volet (0% = totalement fermé; 100 % = totalement ouvert) ôx = incrément de déplacement du voletPvolet = position of the flap (0% = fully closed; 100% = fully open) ôx = increment of movement of the flap
PV = lecture de la température ambiante dans la caisse en °CPV = reading of the ambient temperature in the body in ° C
SP = Consigne de régulation pour la température interne à la caisse (par exemple située entre 2 et 8°C)SP = Regulation setpoint for the internal temperature at the cash register (for example between 2 and 8 ° C)
Porte = Contact d’ouverture de porte(s) (0 = fermée(s) ; 1 = Ouverte(s))Door = Door open contact (s) (0 = closed; 1 = Open)
Par ailleurs, il est connu que la surface d’échange en froid se couvre de « givre » par la condensation de l’air ambiant qui gèle à son contact, air ambiant qui est toujours caractérisé par un certain degré d’humidité. Cette couche de givre, peu adhérente, dégrade le coefficient d’échange du système. On rappellera ici que le givre qui se dépose dans de telles situations est un givre particulier qu’on peut qualifier de « givre cryogénique », volumineux et peu dense, sorte de neige.Furthermore, it is known that the cold exchange surface is covered with "frost" by the condensation of ambient air which freezes on contact, ambient air which is always characterized by a certain degree of humidity. This layer of frost, not very adherent, degrades the exchange coefficient of the system. It will be recalled here that the frost which deposits in such situations is a particular frost which can be described as "cryogenic frost", bulky and sparse, a kind of snow.
Le volet de régulation est alors avantageusement équipé d’un racloir, par exemple en son extrémité, afin d’éliminer cette couche de givre cryogénique en un certain nombre d’allers/retours (réglable). Ce givre ne doit pas tomber sur le chargement situé sous l’échangeur (mouillage des emballages). Aussi il est préférable de prévoir un élément de collecte ainsi que l’évacuation des condensats.The regulating flap is then advantageously equipped with a scraper, for example at its end, in order to remove this layer of cryogenic frost in a certain number of back and forth (adjustable). This frost must not fall on the load located under the exchanger (wetting of the packaging). Also it is better to provide a collection element as well as the evacuation of condensates.
La figure 3 illustre un mode de réalisation d’un système de racloir conforme à l’invention, racloir que l’on peut qualifier de racloir « à bascule » :FIG. 3 illustrates an embodiment of a squeegee system according to the invention, a squeegee which can be described as a "rocker" squeegee:
- le racloir 4 est fixé au volet par un axe/butée permettant d’être au contact de la surface d’échange dans le sens « aller » (a)) et de basculer pour ne pas « gratter » dans le sens « retour » (b)).- the scraper 4 is fixed to the flap by an axis / stop making it possible to be in contact with the exchange surface in the "go" direction (a)) and to tilt so as not to "scratch" in the "return" direction (b)).
- le givre gratté est alors récupéré par gravité dans l’élément de collecte 5.- the scraped frost is then recovered by gravity in the collecting element 5.
Selon un des modes de mise en oeuvre de l’invention, l’échangeur est muni d’un ventilateur à faible consommation énergétique (typiquement quelques Watts, en tout état de cause moins de 10 W, ce qui permet de pouvoir utiliser une batterie de recharge standard, compacte et légère) muni d’un variateur de vitesse permettant de générer un débit d'air allant de 0 à plusieurs dizaines de m3/h. Le ventilateur est placé en face avant de l'échangeur, ainsi le jet d'air qu'il génère est orienté vers la plaque d'échange air/neige carbonique et il subit ainsi un minimum de pertes des charges.According to one of the embodiments of the invention, the exchanger is provided with a fan with low energy consumption (typically a few Watts, in any event less than 10 W, which makes it possible to be able to use a battery of standard, compact and light refill) fitted with a speed controller to generate an air flow ranging from 0 to several tens of m 3 / h. The fan is placed on the front face of the exchanger, so the air jet it generates is directed towards the air / dry ice exchange plate and thus undergoes a minimum of pressure losses.
L’échangeur peut de plus être muni d’un déflecteur pour aider à une diffusion homogène du jet l'air sur la plaque en question.The exchanger can also be equipped with a deflector to help homogeneous diffusion of the air jet on the plate in question.
Les tests réalisés par la Demanderesse pour caractériser la présence d’un tel ventilateur muni d’un variateur de vitesse ont démontré les points suivants:The tests carried out by the Applicant to characterize the presence of such a fan fitted with a variable speed drive have demonstrated the following points:
i) l'amélioration des transferts thermiques par convection forcée permettant ainsi d'avoir un temps de descente en température (« Pull-down ») et retour à la température après ouverture de porte beaucoup plus rapide qu'en l'absence du ventilateur ou sa mise sur arrêt ;i) the improvement of the heat transfers by forced convection thus allowing to have a time of descent in temperature ("Pull-down") and return to the temperature after door opening much faster than in the absence of the fan or its shutdown;
ii) l'amélioration de l'homogénéité de température dans le volume refroidi.ii) improving the temperature uniformity in the cooled volume.
