Description
La présente invention concerne une structure de centrale de réfrigération destinée à fournir un fluide frigorigène sous pression qui est détendu au niveau de postes à réfrigérer.The present invention relates to a refrigeration plant structure for supplying pressurized refrigerant which is expanded at refrigeration stations.
La présente invention s'applique tout particulièrement aux systèmes de réfrigération utilisés dans des magasins à grande surface. Dans de tels magasins, on trouve généralement, sur un seul niveau, plusieurs postes ou groupes de postes à réfrigérer: des chambres froides disposées hors de portée du public, des bacs et des armoires de congélation disposés dans la surface de vente, et divers bacs de réfrigération à des températures supérieures à 0°C, par exemple pour les étals de boucherie, de poissonnerie, de vente de fruits et légumes, de fromagerie, de produits frais, etc.The present invention is particularly applicable to refrigeration systems used in department stores. In such stores, there are generally, on a single level, several stations or groups of stations to be refrigerated: cold rooms placed out of reach of the public, bins and freezer cabinets arranged in the sales area, and various bins refrigeration at temperatures above 0 ° C, for example for butcher's, fishmonger's, fruit and vegetable, cheese, fresh produce, etc. stalls.
La figure 1 représente de façon très schématique et incomplète un exemple d'agencement de bâtiment servant de magasin à grande surface. Ce bâtiment comprend une zone de vente 1 accessible aux clients dans laquelle se trouvent de nombreux présentoirs à étagères 2 portant des marchandises offertes à la vente. La surface de vente comprend des zones froides 3 par exemple des vitrines, armoires ou bacs frigorifiques contenant des produits congelés accessibles à la clientèle.FIG. 1 very schematically and incompletely shows an example of a building arrangement serving as a big box store. This building includes a sales area 1 accessible to customers in which there are
Le bâtiment d'un magasin à grande surface comprend également généralement sur l'un de ses longs côtés une zone de service 10 comprenant par exemple une région de stockage et des chambres froides 11. On trouve souvent à la limite entre la zone de service et la surface de vente des comptoirs de vente de produits frais tels qu'un comptoir de boucherie 12 et un comptoir de fromagerie 13.The building of a big-box store also generally comprises on one of its long sides a
Plutôt que de refroidir individuellement chacune des enceintes devant être refroidies 3, 11, 12, 13, on utilise classiquement dans ce genre de magasin à grande surface une salle des machines centralisée contenant une centrale frigorifique servant de source de liquide frigorigène pour toutes les régions à refroidir. Cette salle des machines ou local technique 15 est représentée à titre d'exemple dans un angle du bâtiment. Ce local technique est d'ailleurs pour des raisons d'économie de place souvent disposé à mi-hauteur du magasin, les grandes surfaces comprenant couramment un seul niveau dans la surface de vente et deux niveaux dans la partie de service, le deuxième niveau comprenant par exemple des bureaux.Rather than individually cooling each of the enclosures to be cooled 3, 11, 12, 13, conventionally in this type of big box store, a centralized machine room containing a refrigeration plant serving as a source of refrigerant for all the regions cool. This machine room or
Ce local technique 15 comprend les moyens nécessaires pour fournir un fluide frigorigène sous pression, par exemple un compresseur 16 avec ses moteurs et moyens d'alimentation. Ce compresseur est associé à un condenseur 17 généralement disposé en dehors du local technique, par exemple sur le toit et associé à des moyens de ventilation pour le refroidir, ce condenseur renvoyant le fluide sous pression vers un réservoir 18 d'où il est transmis par des canalisations 19 aux divers postes à refroidir dont chacun est associé à un détendeur 20 dont un seul est représenté à l'entrée de l'une des chambres froides Des canalisations 21 de retour du fluide frigorigène vers le compresseur 16 éventuellement par l'intermédiaire d'un évaporateur sont également prévues. Les diverses canalisations 19 de fluide frigorigène sous pression proviennent éventuellement de plusieurs machines frigorifiques distinctes disposées dans la salle des machines.This
Ce type d'installation, couramment adopté pour les magasins à grande surface, présente plusieurs inconvénients parmi lesquels on peut mentionner les suivants :
- le fait de prévoir à l'intérieur d'un grand magasin une salle des machines impose, en raison des normes de sécurité généralement fixées pour les lieux publics de prendre des précautions particulières (mur coupe-feu, porte étanche, cloison insonorisée, etc.) ;
- les diverses machines utilisées dans la centrale de réfrigération doivent être montées sur place, ce qui est forcément plus difficile pour le constructeur que d'effectuer un montage en atelier ;
- des longueurs de tuyauteries très importantes existent entre la salle des machines et les diverses enceintes réfrigérées d'où l'existence de tuyauteries longues, coûteuses en elles-mêmes et par le fluide qu'elles contiennent ainsi que par le coût des caniveaux dans lesquelles elles doivent être placées pour ne pas gêner la circulation dans la surface de vente ;
- en outre, ces caniveaux posent problèmes quand on souhaite remodeler la surface du magasin pour placer les enceintes réfrigérées à des emplacements différents (accès, carrelage, trappes de visite, etc.).This type of installation, commonly adopted for large stores, has several drawbacks, among which the following can be mentioned:
- the fact of providing a machine room inside a large store requires, because of the security standards generally set for public places, to take special precautions (fire wall, watertight door, soundproof partition, etc. .);
- the various machines used in the refrigeration plant must be assembled on site, which is necessarily more difficult for the manufacturer than carrying out assembly in the workshop;
- very long lengths of piping exist between the engine room and the various refrigerated chambers, hence the existence of long piping, costly in themselves and by the fluid they contain, as well as by the cost of the gutters in which they must be placed so as not to impede circulation in the sales area;
- In addition, these channels pose problems when you want to reshape the store surface to place the refrigerated enclosures in different locations (access, tiling, inspection hatches, etc.).
Ainsi, la présente invention vise une nouvelle structure de centrale de fourniture de fluide frigorigène particulièrement adaptée aux grandes surfaces de vente sur un seul niveau.Thus, the present invention relates to a new structure of central refrigerant supply particularly suitable for large sales areas on one level.
Dans ce but, la présente invention prévoit une centrale de réfrigération comprenant les éléments classiques de fourniture d'un fluide frigorigène, ces divers éléments étant montés isolément ou par sous-ensembles dans des modules autonomes assemblables sur le lieu d'utilisation en un caisson unique.To this end, the present invention provides a refrigeration plant comprising the conventional elements for supplying a refrigerant, these various elements being mounted individually or in sub-assemblies in autonomous modules which can be assembled at the place of use in a single box. .
De préférence, ce caisson unique forme tunnel de ventilation.Preferably, this single box forms a ventilation tunnel.
Sous un autre aspect, la présente invention prévoit une centrale de réfrigération contenue dans un caisson formant tunnel de ventilation à l'entrée duquel sont disposés des filtres à air, à la sortie duquel sont prévus des extracteurs d'air, et dans lequel sont disposés des compresseurs et leurs accessoires ainsi que des condenseurs.In another aspect, the present invention provides a refrigeration unit contained in a box forming a ventilation tunnel at the entrance of which are arranged air filters, at the outlet of which are provided air extractors, and in which are arranged compressors and their accessories as well as condensers.
Pour un aménagement de bâtiment de magasin à grande surface dans lequel les divers postes devant recevoir des fluides frigorigènes sont situés sensiblement sur un même plan et sont alimentés par groupes individuels par des centrales de réfrigération selon l'invention, ces centrales sont placées sur un plan supérieur du bâtiment et les fluides réfrigérants sont transmis aux ensembles de postes à refroidir par des conduites verticales sur la plus grande partie de leur longueur.For a large-scale store building arrangement in which the various stations to receive refrigerants are located substantially on the same plane and are supplied in individual groups by refrigeration units according to the invention, these units are placed on a plane upper part of the building and the refrigerants are transmitted to the sets of stations to be cooled by vertical pipes over most of their length.
La présente invention permet de résoudre pratiquement tous les inconvénients susmentionnés des machineries antérieures et de leur implantation dans des grandes surfaces de vente. Notamment, les caissons-tunnels constituant la centrale de réfrigération selon l'invention peuvent facilement être placés au-dessus du toit, au niveau des poteaux support de la structure du bâtiment, les fluides frigorigènes étant amenés vers les lieux d'utilisation par des canalisations verticales s'étendant le long de ces poteaux. Dans le cas où l'on veut changer l'implantation des divers postes frigorifiques dans un grand magasin, il suffira de déplacer le bloc de réfrigération placé au niveau du toit vers un autre poteau de la structure pour l'adapter au nouvel emplacement des postes frigorifiques.The present invention makes it possible to solve practically all of the aforementioned drawbacks of prior machineries and their establishment in large sales areas. In particular, the tunnel boxes constituting the refrigeration unit according to the invention can easily be placed above the roof, at the level of the support posts of the building structure, the refrigerants being brought to the places of use by pipes. verticals extending along these posts. If you want to change the location of the various refrigeration stations in a large store, it will be enough to move the refrigeration unit placed at the roof level to another pole of the structure to adapt it to the new location of the stations refrigerators.
Ces objets, caractéristiques et avantages ainsi que d'autres de la présente invention seront exposés plus en détail dans la description suivante d'un mode de réalisation particulier faite en relation avec les figures jointes parmi lesquelles :
- la figure 1 représente à titre d'exemple une implantation classique de centrale de réfrigération dans une grande surface ; et
- la figure 2 représente très schématiquement un exemple de centrale de réfrigération selon la présente invention.
- FIG. 1 shows by way of example a conventional layout of a refrigeration plant in a large area; and
- FIG. 2 very schematically represents an example of a refrigeration plant according to the present invention.
Comme le représente la figure 2, la présente invention prévoit de rassembler tous les éléments d'une centrale de réfrigération dans un caisson 30 constitué de modules élémentaires 31, 32, 33, 34 assemblés par des moyens d'assemblage 36, 37, 38.As shown in FIG. 2, the present invention provides for bringing together all the elements of a refrigeration unit in a
Dans l'exemple représenté en figure 2, le premier module 31 contient uniquement un filtre à air 40. Le deuxième module 32 comprend des armoires électriques 41, des compresseurs 42, et un réservoir de fluide frigorifique comprimé 43. Le troisième module 33 comprend un condenseur 44. Le quatrième module 34 comprend une turbine 45 d'extraction d'air à côté de laquelle on a représenté un moteur d'entraînement 46.In the example shown in Figure 2, the
Ainsi, selon un aspect de l'invention, les différents composants d'une centrale de réfrigération sont montés, en atelier, dans des modules indépendants, transportables indépendamment et assemblables simplement sur le lieu d'utilisation. Bien entendu, entre chacun des modules sont prévus des moyens de liaison électriques et de fluide appropriés. Cette division en modules individuels assure de nombreux avantages quant à la fabrication et à l'entretien. Ainsi, si un élément de la centrale de réfrigération tombe en panne, on pourra facilement réaliser un échange standard du module contenant cet élément pour pouvoir faire une réparation en atelier du module défaillant.Thus, according to one aspect of the invention, the various components of a refrigeration plant are mounted, in the workshop, in independent modules, independently transportable and simply assembled at the place of use. Of course, between each of the modules are provided suitable electrical and fluid connection means. This division into individual modules provides many advantages in terms of manufacturing and maintenance. Thus, if an element of the refrigeration unit breaks down, one can easily carry out a standard exchange of the module containing this element in order to be able to make a repair in the workshop of the faulty module.
Selon un autre avantage de la présente invention, l'ensemble des modules une fois assemblés forme un caisson transportable d'une seule pièce si on le souhaite. Ceci peut être utile pour déplacer la centrale de réfrigération selon l'invention, par exemple comme cela a été indiqué précédemment dans le cas où l'on souhaite remodeler la disposition de la surface de vente d'un grand magasin. A cette fin, chacun des modules 31 à 34 peut être associé à un élément de préhension tel qu'un anneau 48 ou tout autre moyen équivalent pour permettre de déplacer chacun de ces modules ou l'ensemble des modules par exemple au moyen d'une grue.According to another advantage of the present invention, all of the modules once assembled form a transportable box in one piece if desired. This can be useful for moving the refrigeration unit according to the invention, for example as indicated above in the case where it is desired to reshape the layout of the sales area of a department store. To this end, each of the
Selon un autre aspect de la présente invention, on notera que les divers modules comprennent comme cela est représenté sur la figure des parois supérieure et inférieure, avant et arrière, mais pas de parois latérales entre les modules qui communiquent tous une fois assemblés et constituent un caisson-tunnel. Ainsi, une circulation d'air unique provoquée par la turbine 45 à un rythme variable en fonction des conditions atmosphériques permet simultanément de refroidir la salle des machines proprement dite, c'est-à-dire les compresseurs 42, et le ou les condenseurs 44. Bien entendu, dans chacun des modules on pourra prévoir des volets d'orientation du flux d'air, par exemple, dans le module 32, pour refroidir plus particulièrement les têtes de culasse des compresseurs 42.According to another aspect of the present invention, it will be noted that the various modules include, as shown in the figure, the upper and lower walls, front and rear, but no side walls between the modules which all communicate once assembled and constitute a box tunnel. Thus, a single air circulation caused by the
On pourra utiliser comme extracteur deux turbines centrifuges. L'une, à débit variable, est commandée pour que la température interne du caisson reste constante, notamment au niveau du ou des condenseurs 44, quelle que soit la température extérieure. Il en résulte que la pression interne de condensation sera constante et que les fluides frigorifiques seront envoyés à température et pression constantes quelle que soit la température externe. La deuxième turbine sert d'appoint en cas de panne ou de température extérieure anormalement élevée.Two centrifugal turbines can be used as extractor. One, with variable flow, is controlled so that the internal temperature of the box remains constant, in particular at the level of the condenser or condensers, whatever the external temperature. As a result, the internal condensing pressure will be constant and the refrigerants will be sent at constant temperature and pressure regardless of the external temperature. The second turbine serves as a backup in the event of a breakdown or abnormally high outside temperature.
L'air rejeté par les extracteurs peut être renvoyé dans le magasin pour le chauffer, l'air introduit dans le caisson pouvant provenir, au moins partiellement de l'intérieur du magasin.The air rejected by the extractors can be returned to the store to heat it, the air introduced into the box can come, at least partially from inside the store.
D'autre part, on notera que l'invention prévoit dans le premier module un filtre d'entrée 40, et éventuellement dans le dernier module une grille de sortie 47. Ainsi, l'introduction de tout élément étranger et polluant dans la centrale de réfrigération selon l'invention est évitée.On the other hand, it will be noted that the invention provides in the first module an
Bien entendu, la présente invention est susceptible de nombreuses variantes qui apparaîtront au technicien du domaine de l'installation des centrales de réfrigération. Par exemple, alors que l'on a représenté dans le module 32 des armoires électriques 41, des compresseurs 42 et un réservoir de stockage 43, ces divers éléments pourraient être disposés séparément dans des modules indépendants ou être assemblés avec d'autres composants du système. L'assemblage sera dicté par des considérations de commodité de montage, de poids maximum tolérable pour les modules individuels, de simplicité d'accès, etc.Of course, the present invention is susceptible of numerous variants which will appear to the technician in the field of the installation of refrigeration plants. For example, while we have shown in
Comme cela a déjà été indiqué, une centrale de fourniture de fluide frigorigène 30 selon l'invention peut avantageusement être disposée sur le toit du bâtiment d'un magasin à grande surface, par exemple en liaison avec les poteaux de support de la toiture, le fluide réfrigérant entrant et sortant par des canalisations descendant et montant le long de ces poteaux. En outre, la chaleur dégagée par les compresseurs et le condenseur peut éventuellement être récupérée pour permettre une circulation d'air chaud ou d'un fluide chauffé pour assurer le chauffage des locaux de vente ou la distribution d'eau chaude sanitaire.As has already been indicated, a
De préférence, un caisson selon l'invention sera associé à chaque groupe de postes à réfrigérer pour éviter les transferts horizontaux au niveau du sol des fluides frigorigènes. L'installation selon l'invention, outre ses avantages de souplesse d'utilisation et de montage permet également de réduire les longueurs de canalisation entre les lieux d'utilisation et la centrale de réfrigération et donc de diminuer la quantité de fluide de réfrigération à prévoir ainsi que les pertes thermiques. En outre, on pourra utiliser comme fluide frigorigène un monochlorodifluorométhane (R22) plutôt qu'un fluide du type (R502) plus couramment employé mais qui présente des caractéristiques néfastes pour l'environnement.Preferably, a box according to the invention will be associated with each group of stations to be refrigerated to avoid horizontal transfers at ground level of the refrigerants. The installation according to the invention, in addition to its advantages of flexibility of use and assembly also makes it possible to reduce the lengths of pipe between the places of use and the refrigeration unit and therefore to reduce the quantity of refrigeration fluid to be provided as well as heat losses. In addition, a monochlorodifluoromethane (R22) can be used as the refrigerant rather than a fluid of the type (R502) more commonly used but which has harmful characteristics for the environment.
Par ailleurs, pour simplifier la description, on a décrit uniquement à titre d'application de l'invention son emploi dans des magasins à grande surface. Il est clair qu'elle pourra être utilisée dans de nombreuses autres applications et en particulier à l'ensemble de la chaîne du froid de l'industrie agro-alimentaire.Furthermore, to simplify the description, it has been described solely by way of application of the invention its use in stores with large surfaces. It is clear that it can be used in many other applications and in particular in the entire cold chain of the food industry.
