Description

La présente invention concerne un groupe de réfrigération qui comprend un compartiment de logement pour au moins un groupe motocompresseur, ce compartiment étant délimité par un bâti capable de soutenir plusieurs unités modulaires de ventilation juxtaposées entre elles au-dessus du compartiment.The present invention relates to a refrigeration unit which comprises a housing compartment for at least one compressor unit, this compartment being delimited by a frame capable of supporting several units ventilation modules juxtaposed together above the compartment.

On devra comprendre par l'expression "unité de ventilation" les batteries d'échange thermique et les éventuels systèmes de ventilation forcée correspondants qui, associés au groupe motocompresseur, constituent le groupe de réfrigération, que ce dernier travaille en installation frigorifique proprement dite ou en pompe à chaleur.The expression "ventilation unit" should be understood to mean batteries heat exchange system and any corresponding forced ventilation systems which, associated with the compressor unit, constitute the refrigeration unit, that the latter works in a refrigeration installation proper or in a heat pump.

Dans les groupes de réfrigération du type connu, définis ci-dessus, lorsqu'on change la puissance de l'installation, la dimension de la partie correspondant à l'unité de ventilation varie naturellement elle aussi. Ceci implique, d'un côté, un accroissement de la surface ou du nombre des batteries d'échange thermique et, de l'autre côté, une augmentation globale de la structure porteuse dans laquelle les batteries et les motocompresseurs sont montés. Ceci rend globalement plus complexe et plus onéreuse l'étude et la réalisation des groupes de réfrigération, en raison de la nécessité d'adopter des calculs de dimension et des réalisations constructives qui diffèrent en fonction des différentes puissances prévues.In refrigeration units of the known type, defined above, when changing the power of the installation, the dimension of the corresponding part the ventilation unit also naturally varies. This implies, on the one hand, a increase in the area or the number of heat exchange batteries and, on the other hand, an overall increase in the load-bearing structure in which the batteries and motor compressors are fitted. This generally makes it more complex and more expensive the study and the realization of the groups of refrigeration, because of the need to adopt dimension calculations and constructive realizations which differ according to the different powers predicted.

Pour surmonter cet inconvénient, l'invention a pour objet un groupe du type défini ci-dessus, caractérisé en ce que ledit bâti comprend des moyens de support pour supporter l'ensemble des unités modulaires qui font saillie en porte-à-faux sur ce bâti.To overcome this drawback, the invention relates to a group of the type defined above, characterized in that said frame comprises support means to support all of the modular units that project overhang on this built.

Grâce à ce principe de solution, il est possible de réaliser une série de groupes de réfrigération destinés à des installations de différentes puissances, qui comprennent tous un bâti de dimension standard afin de simplifier les activités d'étude et de réalisation des groupes de réfrigération et de réduire les stocks en magasin, ce qui est tout à l'avantage de la diminution des coûts de production. En particulier, pour chaque groupe de réfrigération d'une série de groupes destinés à des installations de différentes puissances, on peut utiliser un bâti unique dont les dimensions maximales seront choisies de façon à ne pas excéder la dimension maximale des éléments de construction, typiquement des éléments profilés, réalisés en tôle pliée, bien que la dimension de la partie de chaque groupe qui fait saillie en porte-à-faux par rapport au bâti croisse encore avec l'accroissement de la puissance de l'installation.Thanks to this principle of solution, it is possible to carry out a series of refrigeration units intended for installations of different powers, which all include a standard size frame to simplify study activities and realization of the refrigeration units and to reduce the stocks in store, this which is all to the benefit of lower production costs. Especially for each refrigeration group from a series of groups intended for different powers, you can use a single frame with maximum dimensions will be chosen so as not to exceed the maximum dimension of the elements of construction, typically profiled elements, made of folded sheet metal, although the dimension of the part of each group which projects in overhang relative to the built still grows with the increase in the power of the installation.

Le fait qu'une partie de l'unité de ventilation fait saillie par rapport au bâti a des effets avantageux sur le fonctionnement du groupe, en ce sens que la circulation de l'air à travers les unités en saillie est améliorée, puisque l'écoulement de l'air à travers ces unités disposées en porte-à-faux n'est pas gêné par la présence du bâti.The fact that part of the ventilation unit protrudes from the frame has advantageous effects on the functioning of the group, in the sense that the circulation of air through the protruding units is improved, since the air flow at through these units arranged in overhang is not hampered by the presence of the frame.

En outre, l'invention permet d'améliorer la distribution des poids des groupes de réfrigération. En effet, le barycentre de la structure est sensiblement centré par rapport au plan, typiquement localisé dans la partie inférieure au niveau du compartiment qui loge les groupes motocompresseurs. En réalisant le bâti avec des dimensions plus compactes que celles de la partie qui comprend les unités de ventilation, il est donc possible de mieux concentrer le poids de l'ensemble du groupe dans la partie inférieure, afin de faciliter sensiblement les opérations liées à son transport et à son installation sur le site.In addition, the invention makes it possible to improve the distribution of the weights of the refrigeration units. Indeed, the barycenter of the structure is substantially centered relative to the plane, typically located in the lower part at the level of the compartment that houses the compressor units. By realizing the frame with more compact dimensions than those of the part which includes the ventilation, it is therefore possible to better concentrate the weight of the whole group in the lower part, in order to appreciably facilitate the operations linked to its transport and its installation on site.

Selon une caractéristique préférée de l'invention, l'ensemble des unités modulaires de ventilation fait saillie en porte-à-faux de façon sensiblement symétrique de part et d'autre du bâti.According to a preferred characteristic of the invention, all of the units modular ventilation projects in a substantially symmetrical overhang on either side of the frame.

De cette façon, le poids du groupe complet, outre qu'il est mieux concentré dans sa partie inférieure, est aussi mieux équilibré par rapport au profil du groupe complet, ce qui est encore à l'avantage de la facilité d'installation et de déplacement.In this way, the weight of the whole group, in addition to being better concentrated in its lower part, is also better balanced in relation to the group profile complete, which is further to the advantage of ease of installation and movement.

Ces avantages sont d'autant plus appréciables que la puissance installée et les dimensions résultantes de l'installation sont grandes.These advantages are all the more appreciable as the installed power and the resulting dimensions of the installation are large.

D'autres caractéristiques et avantages seront mieux compris à la lecture de la description qui va suivre, d'un exemple de réalisation, et en se référant aux dessins annexés sur lesquels :

  • la figure 1 est une vue en perspective d'un groupe de réfrigération selon l'invention,
  • la figure 2 est une vue en perspective qui fait apparaítre l'ossature du groupe de la figure 1,
  • la figure 3 est une vue en élévation avant, en coupe selon la ligne III-III de la figure 1, et
  • la figure 4 est une vue en perspective en coupe et à échelle agrandie d'un détail indiqué par la flèche 4 sur la figure 2.
    • Other characteristics and advantages will be better understood on reading the description which follows, of an exemplary embodiment, and with reference to the appended drawings in which:
  • FIG. 1 is a perspective view of a refrigeration unit according to the invention,
  • FIG. 2 is a perspective view which shows the framework of the group in FIG. 1,
  • FIG. 3 is a front elevation view, in section along the line III-III of FIG. 1, and
  • FIG. 4 is a perspective view in section and on an enlarged scale of a detail indicated by the arrow 4 in FIG. 2.

    • Sur les dessins, un groupe de réfrigération selon l'invention est désigné dans son ensemble par le numéro de référence 1. Le groupe 1 comprend, en position inférieure, un bâti 3 qui délimite un compartiment 4 de logement des groupes motocompresseurs 5 de l'installation.In the drawings, a refrigeration unit according to the invention is designated as a whole by the reference number 1. Group 1 comprises, in position lower, a frame 3 which delimits a compartment 4 for group accommodation motor-compressors 5 of the installation.

    Le bâti 3 a une forme sensiblement parallélipipédique et il est normalement réalisé en assemblant entre eux des profilés métalliques formés par pliage sous pression de tôle.The frame 3 has a substantially rectangular shape and is normally produced by joining together metal profiles formed by folding under sheet metal pressure.

    En particulier, le bâti 3 comprend un cadre de base rectangulaire 6 formé d'une paire d'éléments longitudinaux 9 et d'une paire d'éléments transversaux d'extrémité 11 reliés entre eux, de préférence constitués par des profilés à section transversale en C. Naturellement, la section de ces profilés pourra être différente, avec calcul approprié des dimensions, bien que cette section en C représente un choix préféré.In particular, the frame 3 comprises a rectangular base frame 6 formed a pair of longitudinal elements 9 and a pair of transverse elements end 11 connected together, preferably formed by section profiles transverse in C. Naturally, the section of these profiles may be different, with appropriate calculation of dimensions, although this section in C represents a choice prefer.

    La longueur des éléments longitudinaux 9 est avantageusement choisie de manière à tirer parti de la longueur des profilés réalisables par pliage sous pression de tôle, qui correspond typiquement à environ trois mètres, de sorte que chacun est composé d'une seule pièce. De cette façon, les profilés qui constituent les éléments 9 n'exigent pas l'exécution d'opérations de coupe ni d'assemblage de parties de profilés, de sorte qu'ils sont optimisés du point de vue de la résistance structurale, du poids et du coût.The length of the longitudinal elements 9 is advantageously chosen to so as to take advantage of the length of the profiles achievable by folding under pressure of sheet metal, which typically corresponds to about three meters, so that each is composed of a single piece. In this way, the profiles which constitute the elements 9 do not require the execution of cutting operations or the assembly of profile parts, so they are optimized in terms of structural strength, weight and Cost.

    Entre les deux éléments 9 du cadre 6, sont interposés des éléments profilés auxiliaires 10, par exemple à section transversale en oméga, qui s'étendent parallèlement aux éléments transversaux 11 et permettent de fixer les groupes motocompresseurs 5 de manière à les relier rigidement au bâti 3.Between the two elements 9 of the frame 6, are interposed profiled elements auxiliaries 10, for example with an omega cross section, which extend parallel to the transverse elements 11 and make it possible to fix the groups motor compressors 5 so as to rigidly connect them to the frame 3.

    A chacun des éléments longitudinaux 9 sont aussi reliés rigidement plusieurs montants verticaux 13, par exemple trois montants 13 pour chaque élément 9, avantageusement réalisés à l'aide de profilés en caisson. Au sommet des montants 13 est ensuite fixé un châssis 20 destiné à supporter plusieurs unités modulaires de ventilation 24, juxtaposées entre elles au-dessus du compartiment 4.To each of the longitudinal elements 9 are also rigidly connected several vertical uprights 13, for example three uprights 13 for each element 9, advantageously made using box profiles. At the top of the uprights 13 is then fixed a frame 20 intended to support several modular units of ventilation 24, juxtaposed together above compartment 4.

    En particulier l'ensemble constitué par les unités modulaires 24 fait saillie en porte-à-faux par rapport au bâti 3, de préférence d'une façon sensiblement symétrique de part et d'autre du bâti 3. A une extrémité de l'ensemble des groupes modulaires 24 est associé, d'une façon connue en soi, un panneau de commande du groupe 1, désigné par le numéro de référence 26 sur la figure 1.In particular, the assembly constituted by the modular units 24 projects in overhang with respect to the frame 3, preferably in a substantially symmetrical manner on either side of the frame 3. At one end of all the modular groups 24 is associated, in a manner known per se, with a group 1 control panel, designated by the reference number 26 in Figure 1.

    Si l'extension des parties en porte-à-faux au-delà du bâti 3 l'exige, on peut interposer des structures respectives de contreventement 22 réalisées, par exemple, au moyen de jambes de force inclinées, pour améliorer le soutien des parties en porte-à-faux. Plus précisément, le châssis de support 20 comprend plusieurs traverses 28, reliées rigidement, par leurs extrémités opposées, à une paire de montants respectifs 13, chaque traverse 28 étant réalisée, par exemple à l'aide d'un profilé qui a une section transversale en C. Au-dessus des traverses 28, et au droit de leurs extrémités, sont ensuite fixés deux longerons 30 parallèles, destinés à l'assemblage des unités modulaires de ventilation 24.If the extension of the cantilevered parts beyond the frame 3 requires it, interpose respective bracing structures 22 made, for example, by means of inclined struts to improve the support of the cantilevered parts. More specifically, the support frame 20 comprises several crosspieces 28, rigidly connected by their opposite ends to a pair of respective uprights 13, each cross member 28 being produced, for example using a profile which has a cross section in C. Above the crosspieces 28, and in line with their ends, are then fixed two parallel beams 30, intended for the assembly of the units ventilation modules 24.

    En particulier, chaque longeron 30 a une section transversale de la forme générale d'un S, de manière à présenter une aile rabattue 30a, pour la fixation de la partié inférieure d'une batterie ou d'une unité de ventilation verticale 32 des condenseurs, et une autre aile rabattue 30b, inclinée par rapport à l'aile 30a, servant à la fixation de la partie inférieure d'une batterie inclinée 34.In particular, each spar 30 has a cross section of the general shape of an S, so as to present a folded wing 30 a , for fixing the lower part of a battery or of a vertical ventilation unit 32 of the condensers, and another folded-down wing 30 b , inclined with respect to the wing 30 a , used for fixing the lower part of an inclined battery 34.

    A leur tour, les deux batteries inclinées 34 sont fixées l'une à l'autre à leurs extrémités supérieures à l'aide d'une paire de profilés 36 juxtaposés entre eux, et ayant une section transversale sensiblement en L, de sorte que les batteries 34 prennent une configuration en V inversé.In turn, the two inclined batteries 34 are fixed to each other at their upper ends using a pair of profiles 36 juxtaposed between them, and having a substantially L-shaped cross section, so that the batteries 34 take an inverted V configuration.

    Les profilés en L 36 sont à leur tour reliés, au sommet des batteries verticales 32 à l'aide d'éléments de couverture et de soutien des groupes de ventilation, connus en soi.The L 36 profiles are in turn connected to the top of the batteries vertical 32 using cover and group support elements ventilation, known per se.

    Dans un mode préféré, des profilés respectifs de renforcement à section transversale en C sont fixés aux extrémités supérieures de chaque batterie 32, 34, de manière que ces batteries soient reliées au reste de la structure par l'intermédiaire de ces profilés.In a preferred embodiment, respective section reinforcement profiles transverse in C are fixed to the upper ends of each battery 32, 34, of so that these batteries are connected to the rest of the structure through these profiles.

    Il reste entendu que, bien que les sections indiquées pour les profilés représentent des choix préférés pour la réalisation du châssis de la présente invention, elles pourront être avantageusement remplacées par des sections différentes, avec calcul approprié des dimensions. It is understood that, although the sections indicated for the profiles represent preferred choices for the realization of the chassis of the present invention, they can advantageously be replaced by different sections, with appropriate calculation of dimensions.

    Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple sans sortir du cadre de l'invention.Of course, various modifications can be made by humans from art to the device which has just been described only by way of example without departing from the part of the invention.
