Abstract
Description
L'invention se rattache au secteur technique des appareils climatiseurs à production réversible de distribution d'air chaud ou d'air froid.The invention relates to the technical sector of air conditioning units with reversible production of hot air distribution or cold air.
La technologie actuelle des climatiseurs et de leurs composants présente plusieurs inconvénients majeurs. Un premier est de générer en effet de condensation dû aux échanges thermiques inhérents à la compression de certains gaz. Un second inconvénient réside dans le fait que les climatiseurs actuels sont souvent associés à des fluides réfrigérant avec la production de gaz nocifs à l'environnement présentant un pouvoir de réchauffement beaucoup plus élevé que celui du CO2 (jusqu'à 2.000 fois plus), dont les fuites sont fréquentes et dont le recyclage en fin de vie est contenu. Bien qu'il y ait une utilisation de dispositif de filtration, il apparaît aussi que les systèmes actuels de climatisation sont parfois la source de développement et de la propagation de certaines bactéries qui provoquent des légionelloses. D'importantes recherches ont été menées par de très nombreux fabricants de climatiseurs, mais on constate en pratique que tout ou partie des inconvénients précités demeurent.The current technology of air conditioners and their components has several major disadvantages. A first is to generate condensation effect due to heat exchange inherent in the compression of certain gases. A second disadvantage is that current air conditioners are often associated with refrigerant fluids with the production of environmentally harmful gases with a much higher warming potential than CO2 (up to 2,000 times more), of which leaks are frequent and end-of-life recycling is contained. Although there is a use of filtration device, it also appears that current air conditioning systems are sometimes the source of development and spread of certain bacteria that cause legionellosis. Extensive research has been conducted by many manufacturers of air conditioners, but it is found in practice that some or all of the aforementioned disadvantages remain.
La démarche du demandeur a donc été de s'orienter sur une conception radicalement différente de celles des climatiseurs actuels pour s'affranchir notamment des problèmes de condensation et d'évacuation des condensats.The applicant's approach was therefore to focus on a concept radically different from that of current air conditioners to overcome the problems of condensation and condensate evacuation.
Aussi, le premier but recherché selon l'invention était de supprimer l'effet de condensation en ne faisant plus appel à des composants du climatiseur les générant, et donc sans utilisation de fluides réfrigérant.Also, the first object of the invention was to eliminate the effect of condensation by no longer using components of the air conditioner generating them, and therefore without the use of refrigerant fluids.
Un deuxième but recherché selon l'invention était de concevoir un nouveau climatiseur permettant d'éviter tout phénomène de risque de pollution de l'environnement.A second aim of the invention was to design a new air conditioner to avoid any risk of pollution of the environment.
Un troisième but recherché était de concevoir un climatiseur dans des conditions économiques de fabrication très concurrentielles par rapport aux climatiseurs actuels et pouvant trouver des applications très variées.A third goal sought was to design an air conditioner in economically competitive manufacturing conditions compared to current air conditioners and can find a wide variety of applications.
Un autre but recherché était de concevoir un climatiseur présentant dans son agencement nouveau une très facile adaptation de l'effet produit de chauffage et de refroidissement pouvant être commandés par pilotage informatique.Another object sought was to design an air conditioner having in its new arrangement a very easy adaptation of the heating and cooling effect produced that can be controlled by computer control.
Ces buts et d'autres encore ressortiront bien de la suite de la description.These and other goals will be apparent from the rest of the description.
Le concept utilisé par le climatiseur fait référence à l'utilisation de la mécanique des fluides sans adjonction de gaz pour assurer les fonctions recherchées. Ce concept est connu du document
Selon une première caractéristique de l'invention, le climatiseur est remarquable en ce qu'il comprend, disposés et agencés dans une enceinte de réception et successivement, un premier moyen sous forme d'un compresseur axial muni de pales sur sa périphérie et alimenté par un groupe moteur intégré entraînant la mise en circulation d'air à une vitesse donnée, un second moyen sous forme d'un stator redresseur axial ayant pour fonction de créer une pression statique supérieure à la pression atmosphérique en transférant la veine d'air obtenue dans un troisième moyen sous forme d'un compresseur centrifuge statique ayant pour fonction la création d'un flux rotationnel avec une pression statique fluctuant en fonction de l'élévation de température tout au long du flux, la veine d'air étant acheminée dans un quatrième moyen constitué par un redresseur diffuseur axial, ledit redresseur étant creux intérieurement pour la circulation d'air ambiant et ayant extérieurement pour fonction de redresser le flux tourbillonnaire en flux axial et de détendre la pression, et en ce qu'un cinquième moyen constitué par une vanne de transfert s'adapte autour du quatrième moyen pour réguler ou non le passage d'air chaud, avec adjonction d'air ambiant, et en ce qu'un sixième moyen constitué par un vortex permet l'accélération de la veine d'air dans un effet tourbillonnaire avant de pénétrer dans un septième moyen constitué par une chambre de détente produisant le froid, et diriger la veine d'air dans le distributeur d'air final aux conditions de températures choisies, et en ce que l'ensemble desdits moyens sont disposés dans une enveloppe de protection et de liaison.According to a first characteristic of the invention, the air conditioner is remarkable in that it comprises, arranged and arranged in a reception chamber and successively, a first means in the form of an axial compressor provided with blades on its periphery and powered by an integrated motor unit driving the circulation of air at a given speed, a second means in the form of an axial stator stator whose function is to create a static pressure greater than the atmospheric pressure by transferring the air stream obtained in a third means in the form of a static centrifugal compressor whose function is to create a rotational flow with a static pressure fluctuating as a function of the temperature rise throughout the flow, the air stream being conveyed in a fourth means constituted by an axial diffuser rectifier, said rectifier being hollow internally for the circulation of ambient air and having externally for the purpose of straightening the vortex flow in axial flow and to relax the pressure, and in that a fifth means constituted by a transfer valve fits around the fourth means for regulating or not the passage of hot air, with adding ambient air, and in that a sixth vortex means allows the vortex to accelerate in a vortex effect before entering a seventh means consisting of an expansion chamber producing the cold, and directing the air stream into the final air distributor at the selected temperature conditions, and in that all of said means are arranged in a protective envelope. on and liaison.
Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These and other characteristics will be apparent from the rest of the description.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.
L'appareil climatiseur selon l'invention est représenté dans son ensemble par (A), et s'intègre dans une installation (I) représentée
Il convient dès lors d'exposer les caractéristiques du climatiseur et de ses différents éléments constitutifs.It is therefore necessary to describe the characteristics of the air conditioner and its various constituent elements.
Ce climatiseur comprend une pluralité de moyens disposés et agencés successivement en alignement dans une enceinte de réception (10), elle-même intégrée et protégée par le carter (1) précité. Cette enceinte (2) est de configuration cylindrique par exemple en étant réalisée en deux demi-parties cylindriques (10a-10b) qui présentent le long de leur bordure longitudinale extérieure des bandes (10c) permettant par rapprochement leur liaison et fixation par des moyens du type boulonnage ou autres. Les différents composants du climatiseur sont ainsi positionnés et fixés les uns aux autres et aussi par rapport à ladite enceinte.This air conditioner comprises a plurality of means arranged and successively arranged in alignment in a receiving chamber (10), itself integrated and protected by the housing (1) above. This enclosure (2) is of cylindrical configuration for example by being made in two cylindrical half-portions (10a-10b) which have along their outer longitudinal edge strips (10c) allowing their connection and fixing by means type bolting or others. The different components of the air conditioner are thus positioned and fixed to each other and also relative to said enclosure.
Le climatiseur comprend ainsi :
- un premier moyen (11) sous forme d'un compresseur axial muni de pales (11a) sur sa périphérie et alimenté par un groupe moteur (12) intégré entraînant la mise en circulation d'air à une vitesse donnée ;
- un second moyen (13) sous forme d'un stator redresseur axial ayant pour fonction de créer une pression statique supérieure à la pression atmosphérique en transférant la veine d'air obtenue ;
- dans un troisième moyen (14) sous forme d'un compresseur centrifuge statique ayant pour fonction la création d'un flux rotationnel avec une pression statique fluctuant en fonction de l'élévation de température tout au long du flux ;
- un quatrième moyen (15) sous forme d'un redresseur diffuseur axial creux intérieurement pour la circulation d'air ambiant et ayant extérieurement pour fonction de redresser le flux tourbillonnaire en flux axial et de détendre la pression ;
- un cinquième moyen (16) constitué par une vanne transfert s'adaptant sur le redresseur diffuseur d'air pour réguler ou non le passage d'air chaud avec adjonction d'air ambiant ;
- un sixième moyen (17) constitué par un vortex permettant l'accélération de la veine d'air dans un effet tourbillonnaire ;
- un septième moyen (18) disposé en bout du vortex et constituant une chambre de détente produisant le froid pour diriger la veine d'air dans le distributeur final d'air aux conditions de température choisie.
- first means (11) in the form of an axial compressor provided with blades (11a) on its periphery and powered by an integrated motor unit (12) causing the circulation of air at a given speed;
- second means (13) in the form of an axial stator stator whose function is to create a static pressure greater than the atmospheric pressure by transferring the air stream obtained;
- in a third means (14) in the form of a static centrifugal compressor whose function is to create a rotational flow with a static pressure fluctuating as a function of the rise in temperature throughout the flow;
- fourth means (15) in the form of an internally hollow axial diffuser rectifier for the circulation of ambient air and having the function externally of straightening the vortex flow in axial flow and of relieving the pressure;
- fifth means (16) constituted by a transfer valve fitting on the air diffuser rectifier to regulate or not the passage of hot air with the addition of ambient air;
- a sixth means (17) constituted by a vortex allowing the acceleration of the air stream in a vortex effect;
- a seventh means (18) disposed at the end of the vortex and constituting an expansion chamber producing the cold to direct the air stream into the final air distributor at the selected temperature conditions.
Il convient dès lors de décrire chacun desdits moyens (11 à 18) de manière plus spécifique en se référant aux figures des dessins.It is therefore appropriate to describe each of said means (11 to 18) more specifically with reference to the figures of the drawings.
Les différents moyens (11 à 18) sont ainsi représentés en ordre de montage aux
Le premier moyen (11) est ainsi le compresseur axial représenté aux
Le second moyen (13) est le stator diffuseur axial qui est fixé et solidarisé à l'enveloppe (10) par tous moyens de liaison appropriés. Ce second moyen (13) est situé sur la partie d'arbre (12c) entre la bride de fixation (12e) et la partie conique (12a).The second means (13) is the axial diffuser stator which is fixed and secured to the casing (10) by any appropriate connecting means. This second means (13) is located on the shaft portion (12c) between the attachment flange (12e) and the conical portion (12a).
Le stator diffuseur comprend 10 pales (13a) par exemple en aluminium. De préférence, la liaison avec l'enveloppe (11) s'effectue par l'extrémité des pales (13a). Ces pales (13a) sont disposées dans le prolongement des pales (11a) formées sur le compresseur, mais contrairement à celles-ci qui ont une configuration en hélice, les pales (13a) sont disposées dans le sens axial longitudinal du stator redresseur axial. Elles ont une configuration symétrique avec une entrée (13a1) progressive, et une seconde partie (13a2) dégressive, de sorte à former un profil en goutte d'eau. Ainsi qu'il apparaît
Il convient dès lors d'exposer le troisième moyen ( 14) constitué par un compresseur centrifuge statique représenté aux
Ce compresseur (14) comprend un corps tubulaire (14a) s'ajustant autour du bloc moteur (12) et recevant selon une caractéristique particulière deux séries de pales primaires (14b) et secondaires (14c) de caractéristiques différentes. La première série de pales (14b) comprend cinq pales disposées en hélice à géométrie et à pas variable. Ces pales primaires (14b) sont développées de manière à faire un tour complet autour du corps (14a) récepteur dans la configuration représentée
La surface de chaque côté de la pale est concave sans traitement de surface particulier. Ainsi, le compresseur centrifuge statique (14) permet de transformer le flux d'air axial en provenance du moyen (13) en un flux rotationnel afin d'accélérer celui-ci, tout en conservant la pression statique établie à la sortie du stator diffuseur axial (13).The surface of each side of the blade is concave without special surface treatment. Thus, the static centrifugal compressor (14) makes it possible to transform the axial air flow coming from the means (13) into a rotational flow in order to accelerate it, while maintaining the static pressure established at the outlet of the diffuser stator. axial (13).
La centrifugation est obtenue par le renversement du flux d'air axial le long des pales et la combinaison des effets tourbillonnaires donnés par les différents types de pales.Centrifugation is achieved by reversing the axial airflow along the blades and combining the swirling effects given by the different types of blades.
Les pales sont construites par projection de plusieurs surfaces non réglées d'après l'élaboration des triangles de vitesse sur la génératrice du centre de masse et du centre inertiel de chaque surface. Ces surfaces sont ensuite projetées par enroulement sur la surface définitive de chaque pale, afin de donner un effet giratoire au flux d'air. Dès que le flux rotationnel est créé, il s'ensuit une augmentation de pression sur les surfaces, due à la force de centrifugation créée par l'enroulement du flux et par la retrainte du conduit convergent entre les surfaces d'appui. Dans cette phase, la pression statique fluctue en fonction de l'élévation de température tout au long du trajet.The blades are constructed by projecting several unregulated surfaces according to the development of velocity triangles on the generatrix of the center of mass and the inertial center of each surface. These surfaces are then projected by winding on the final surface of each blade, to give a gyratory effect to the flow of air. As soon as the rotational flow is created, there is an increase in pressure on the surfaces, due to the centrifugal force created by the winding of the flow and the restreatment of the convergent duct between the bearing surfaces. In this phase, the static pressure fluctuates as a function of the temperature rise throughout the journey.
Il convient d'exposer les caractéristiques du quatrième moyen (15) constitué par le redresseur diffuseur axial représenté
Ce redresseur diffuseur axial est susceptible de coopérer et de permettre le positionnement et l'emmanchement d'un cinquième moyen (16) constitué par une vanne transfert. Celle-ci présente un corps cylindrique (16a) venant s'emmancher dans le corps (15a) du redresseur (15), et elle présente une collerette (16b) débordante de configuration cylindrique. Cette collerette en forme de couronne est aménagée avec une pluralité de lumières (16c) autorisant un passage et une circulation d'air dans le corps (16a). Sur la couronne (16b) est rapportée et positionnée une bague (20) de forme complémentaire susceptible d'être pivotée angulairement par rapport à ladite couronne (16b). A cet effet, la bague présente elle-même des parties pleines (20a) en forme de cache qui ont des formes et dimensions complémentaires aux lumières (16c) pour les obturer en tout ou partie selon la position de la bague sur la couronne (16b). Un moyen de réglage (21) et d'entraînement de la bague sur la couronne est ainsi disposé sur le corps du redresseur (15) pour permettre l'orientation angulaire appropriée de la vanne transfert. Selon le degré d'ouverture et de fermeture de la vanne transfert, on permet l'introduction et le mélange d'air ambiant avec l'air produit et chauffé par les différents moyens décrits précédemment.This axial diffuser rectifier is capable of cooperating and allowing the positioning and fitting of a fifth means (16) constituted by a transfer valve. It has a cylindrical body (16a) coming into the body (15a) of the rectifier (15), and it has a flange (16b) projecting cylindrical configuration. This ring-shaped collar is arranged with a plurality of lights (16c) allowing a passage and an air flow in the body (16a). On the ring (16b) is reported and positioned a ring (20) of complementary shape may be rotated angularly relative to said ring (16b). For this purpose, the ring itself has solid parts (20a) in the form of a cover which have shapes and dimensions complementary to the slots (16c) for closing them in whole or in part according to the position of the ring on the ring (16b). ). Adjusting means (21) and driving the ring on the ring gear is thus disposed on the body of the rectifier (15) to allow the appropriate angular orientation of the transfer valve. Depending on the degree of opening and closing of the transfer valve, it is possible to introduce and mix ambient air with the air produced and heated by the various means described above.
Il convient dès lors d'exposer le sixième moyen (17) constitué par un vortex. Celui-ci correspond au disque cylindrique (17a) creux dans sa partie centrale et recevant une pluralité de pales (17b) par exemple en aluminium, au nombre de 10 par exemple. Ces pales sont disposées en étoile avec une configuration en tronc de cône. Ce vortex a pour fonction de donner une vitesse stable et constante au flux d'air par un mouvement de rotation entre les pales, et il prépare le transfert de flux d'air produit dans la chambre de détente (18) produisant le froid disposée en aval. Celle-ci présente une configuration cylindrique avec un nez (18a) en ogive.It is therefore appropriate to set out the sixth means (17) constituted by a vortex. This corresponds to the cylindrical disc (17a) hollow in its central part and receiving a plurality of blades (17b) for example of aluminum, 10 in number for example. These blades are arranged in a star configuration with a truncated cone. This vortex has the function of giving a stable and constant speed to the flow of air by a rotational movement between the blades, and it prepares the transfer of air flow produced in the expansion chamber (18) producing the cold disposed downstream. It has a cylindrical configuration with a nose (18a) ogive.
La climatisation ainsi constituée par l'ensemble de ces moyens permet la production d'air chaud ou froid selon des plages de températures adaptées en fonction des applications de l'invention, et ce, grâce à la combinaison des effets circulatoires d'air donnés par les différents moyens décrits.The air conditioning thus constituted by all these means allows the production of hot or cold air according to temperature ranges adapted according to the applications of the invention, and this, thanks to the combination of the circulatory effects of air given by the various means described.
Le groupe moteur et la vanne transfert, ainsi que leurs commandes, sont raccordés à une carte numérique pouvant être pilotée par ordinateur via une prise RS232 ou autre.The power unit and the transfer valve and their controls are connected to a computer-controlled digital card via an RS232 or other socket.
La climatisation selon l'invention répond aux différents problèmes posés. La configuration (11) de ces différents composants et moyens et le nombre de pales est donnée à titre d'exemple dans le cadre d'une optimisation de fonctionnement du climatiseur.The air conditioning according to the invention responds to the various problems posed. The configuration (11) of these various components and means and the number of blades is given as an example in the context of an optimization of operation of the air conditioner.
Ces moyens peuvent être fabriqués en matériau aluminium, mais aussi selon les applications des climatiseurs, ils peuvent être réalisés par moulage en matériau plastique et composite ou autre, tenant compte des contraintes de fonctionnement.These means can be made of aluminum material, but also according to the applications of air conditioners, they can be made by molding plastic material and composite or other, taking into account the operating constraints.
