Description
La présente invention à pour objet une méthode / un système de chauffage basé sur le principe de la friction de fluides.The subject of the present invention is a method / heating system based on the principle of friction of fluids.
Ce principe est bien connu en soi et a donné lieu à divers développements dans le domaine du chauffage à circulation d'air.This principle is well known per se and has given rise to various developments in the field of circulating air heating.
On connait ainsi le brevet américain
Afin d'éviter les pertes de chaleur par une amenée continue d'air ambiant, le circuit d'air communiquant avec l'enceinte de chauffage frictionnel peut être obturé à l'aide d'une vanne directionnelle, dont l'objectif n'est donc clairement pas d'assurer une surpression dans le système par rapport à la pression ambiante.In order to avoid heat losses by a continuous supply of ambient air, the air circuit communicating with the friction heating chamber can be closed by means of a directional valve, the objective of which is not therefore clearly not to ensure an overpressure in the system compared to the ambient pressure.
On a pu constater que le rendement énergétique des systèmes de chauffage par friction de gaz est relativement mauvais.It has been found that the energy efficiency of gas friction heating systems is relatively poor.
L'inventeur de la présente méthode et de la présente chaudière à maintenant trouvé, de manière surprenante, que le rendement énergétique des systèmes de chauffage par friction de gaz peut être considérablement augmenté en intégrant une turbine de circulation de gaz, connue en soi, et un échangeur de chaleur fluide / fluide, du type "chaudière haut rendement" de chauffage central, également connu en soi, dans un système compacte, opérant à une pression nettement supérieure à la pression atmosphérique.The inventor of this method and of the present boiler has now surprisingly found that the energy efficiency of gas friction heating systems can be considerably increased by integrating a gas circulation turbine, known per se, and a fluid / fluid heat exchanger, type "high efficiency boiler" central heating, also known per se, in a compact system, operating at a pressure clearly above atmospheric pressure.
L'invention a dès lors pour objectif de procurer un système de chauffage par friction de gaz comprenant une turbine de circulation de gaz et un échangeur de chaleur, dans lequel la turbine de circulation de gaz et l'échangeur de chaleur constituent un circuit fermé du point de vue du gaz frictionnel, tandis que la pression du gaz frictionnel dans le circuit fermé est supérieure à 250 kPa (2,5 bar), et plus particulièrement située entre 300 et 1000 kPa (3 et 10 Bar), et de manière tout à fait préférée entre 300 et 500 kPa (3 et 5 bar).The object of the invention is therefore to provide a gas friction heating system comprising a gas circulation turbine and a heat exchanger, in which the gas circulation turbine and the heat exchanger constitute a closed circuit of the gas circulation turbine. point of view of the frictional gas, while the pressure of the frictional gas in the closed circuit is greater than 250 kPa (2.5 bar), and more particularly between 300 and 1000 kPa (3 and 10 Bar), and in a manner preferably between 300 and 500 kPa (3 and 5 bar).
Selon un mode de réalisation préféré de l'invention, la pression du gaz peut plus particulièrement être supérieure à 250 kPa à l'entrée de la turbine, tandis que différence de pression entre l'entrée et la sortie de la turbine est plus particulièrement supérieure à 25 kPa.According to a preferred embodiment of the invention, the gas pressure may more particularly be greater than 250 kPa at the inlet of the turbine, while the pressure difference between the inlet and the outlet of the turbine is more particularly greater than at 25 kPa.
Autrement dit, selon cette particularité préférée de l'invention, le circuit de circulation du gaz frictionnel comprenant l'échangeur de chaleur engendre une résistance correspondant à un différentiel de pression entre la pression d'entrée et la pression de sortie supérieure à 0,25 bar.In other words, according to this preferred feature of the invention, the circulation circuit of the frictional gas comprising the heat exchanger generates a resistance corresponding to a differential pressure between the inlet pressure and the outlet pressure greater than 0.25. bar.
Selon encore une autre particularité préférée supplémentaire de l'invention la différence de pression entre l'entrée et la sortie de la turbine est plus particulièrement d'au moins 10% de la pression du gaz à l'entrée de la turbine.According to yet another additional preferred feature of the invention the pressure difference between the inlet and the outlet of the turbine is more particularly at least 10% of the pressure of the gas at the inlet of the turbine.
L'invention a par ailleurs également pour objectif de procurer une chaudière de chauffage central et/ou de production d'eau chaude ("centrale de chauffe") comprenant des moyens pour générer de la chaleur et des moyens de transfert de la chaleur à l'eau, laquelle chaudière implique plus spécifiquement une génération de chaleur par friction de gaz tandis qu'elle comprend une turbine de circulation de gaz et un échangeur de chaleur réunis en un circuit fermé, du point de vue du gaz frictionnel, dans lequel la pression est supérieure à 250 kPa (2,5 bar), et plus particulièrement situés entre 300 et 1000 kPa (3 et 10 Bar), et de manière tout à fait préférée entre 300 et 500 kPa (3 et 5 bar).The invention also also aims to provide a central heating boiler and / or hot water production ("central heating") comprising means for generating heat and means for transferring heat to the heat. water, which boiler more specifically involves a gas friction heat generation whereas it comprises a gas circulation turbine and a heat exchanger combined in a closed circuit, from the point of view of the frictional gas, in which the pressure is greater than 250 kPa (2.5 bar), and more particularly located between 300 and 1000 kPa (3 and 10 bar), and most preferably between 300 and 500 kPa (3 and 5 bar).
Selon un mode de réalisation préféré de la chaudière selon l'invention, la turbine de circulation de gaz et l'échangeur de chaleur sont plus particulièrement réunis dans un circuit fermé compact et intégré.According to a preferred embodiment of the boiler according to the invention, the gas circulation turbine and the heat exchanger are more particularly combined in a compact and integrated closed circuit.
Selon une particularité préférée supplémentaire de la chaudière selon l'invention, la pression du gaz est plus particulièrement supérieure à 250 kPa à l'entrée de la turbine et la différence de pression entre l'entrée et la sortie de la turbine est supérieure à 25 kPa.According to a further preferred feature of the boiler according to the invention, the gas pressure is more particularly greater than 250 kPa at the inlet of the turbine and the pressure difference between the inlet and the outlet of the turbine is greater than 25. kPa.

II est évident que les principes énoncés ci-dessus sont indépendant du dimensionnement du système / de la chaudière.It is obvious that the principles stated above are independent of the design of the system / boiler.
Selon un mode de réalisation convenant particulièrement pour des applications domestiques courantes le système / la chaudière implique un débit de circulation de la turbine de l'ordre de 150 à 200 m3/h.According to one embodiment particularly suitable for common domestic applications the system / boiler involves a flow rate of the turbine of the order of 150 to 200 m 3 / h.
D'autres particularités et détails de l'invention apparaitront à la lecture des explications suivantes, qui en précisent certaines notions générales et certains aspects de réalisation concrets, en se référant aux dessins annexés, dans lesquels :
- la figure 1 est une représentation schématique d'une "chaudière" selon l'invention, et
- la figure 2 est une représentation stylisée d'un mode de réalisation des éléments fonctionnels d'une telle chaudière.
- FIG. 1 is a schematic representation of a "boiler" according to the invention, and
- Figure 2 is a stylized representation of an embodiment of the functional elements of such a boiler.
Dans le mode de réalisation de l'invention décrit ici et dans les figures 1 et 2, le procédé de réchauffement est basé sur la circulation d'un gaz pressurisé dans un réseau de plaques générant un réchauffement de celui-ci du fait de la friction sur les parois.In the embodiment of the invention described here and in FIGS. 1 and 2, the heating process is based on the circulation of a pressurized gas in a network of plates generating a heating thereof because of the friction on the walls.
Le procédé comprend principalement :
- une turbine (2) entraînée par un moteur électrique (1) dont le système marche/arrêt est réglé par thermostat mesurant la température de sortie du fluide.
- un double réseau de plaques permettant l'échange d'énergie entre le gaz circulant dans un sens tout en s'y réchauffant et le fluide circulant en sens inverse (l'échangeur 7)
- un circuit (8) (9) de distribution du fluide dans l'installation
- une durite de retour (5) d'air vers la turbine
- un mini compresseur (25) pressurisant le gaz et régulé par un pressostat (24).
- a turbine (2) driven by an electric motor (1) whose on / off system is thermostatically controlled measuring the outlet temperature of the fluid.
- a double network of plates allowing the exchange of energy between the gas flowing in one direction while heating up and the fluid flowing in the opposite direction (the exchanger 7)
- a circuit (8) (9) for distributing the fluid in the installation
- a return hose (5) of air towards the turbine
- a mini compressor (25) pressurizing the gas and regulated by a pressure switch (24).
L'air circule à grande vitesse dans un anneau, accéléré par la turbine et réalisant un phénomène de friction sur les plaques formant le micro réseau.The air circulates at high speed in a ring, accelerated by the turbine and realizing a phenomenon of friction on the plates forming the micro-network.
Le principe de production de chaleur est l'échauffement par friction d'un gaz se déplaçant à grande vitesse dans un circuit fermé.The principle of heat generation is the frictional heating of a gas moving at high speed in a closed circuit.
Le rendement énergétique est augmenté grâce au fait que le gaz est mis sous pression.The energy efficiency is increased thanks to the fact that the gas is pressurized.
La friction se produit plus particulièrement dans un réseau de plaques embouties et assemblées par brasage (l'échangeur) dans lesquelles gaz et fluide circulent en sens inverse L'échangeur (7) est composé de plaques déformées de manière à former une micro cannelure entre chaque plaque. L'acier est un acier inox alimentaire percé alternativement en haut et en bas pour permettre de créer un passage en « chicane » une plaque sur deux ou une plaque sur 3 quand l'invention est appliquée dans une fonction de climatiseur.The friction occurs more particularly in a network of stamped plates and assembled by brazing (the exchanger) in which gas and fluid circulate in opposite directions The exchanger (7) is composed of plates deformed so as to form a micro groove between each plate. The steel is a food grade stainless steel pierced alternately up and down to create a "baffle" passage every other plate or plate out of 3 when the invention is applied in an air conditioner function.
Suivant le besoin de l'installation et de l'équipement à pourvoir l'échangeur peut être réalisé avec d'avantage de plaques (interfaces).According to the need of the installation and the equipment to be filled the exchanger can be made with more plates (interfaces).
La circulation du gaz est assurée à pression constante par une turbine spéciale. Celle-ci est entrainée grâce à une transmission par un moteur électrique. La transmission peut suivant le cas démultiplier la vitesse de la turbine et est conçue de manière à optimaliser le rendement de la chaudière / centrale de chauffe.The circulation of the gas is ensured at constant pressure by a special turbine. This is driven by a transmission by an electric motor. The transmission can, depending on the case, increase the speed of the turbine and is designed to optimize the efficiency of the boiler / central heating.
L'effet de la friction est amélioré grâce à la mise sous pression du gaz à l'aide d'un mini compresseur régulé par un pressostat.The effect of friction is improved by pressurizing the gas with a mini compressor regulated by a pressure switch.
La fonctionnalité essentielle de l'échangeur est de :
- 1) Produire des calories par un passage de gaz à grande vitesse sous-pression et transférées à un fluide en circuit fermé ou ouvert.
- 2) Transmettre des frigories.
- 3) Transférer ces calories ou frigories sur le liquide support circulant en sens inverse, vers les circuits intermédiaires (9) et (8).
- 1) Produce calories by passing a high-speed gas under pressure and transferred to a closed or open-circuit fluid.
- 2) Transmit frigories.
- 3) Transfer these calories or frigories on the support liquid circulating in opposite direction, to the intermediate circuits (9) and (8).
Le circuit du liquide chauffé est accéléré par une pompe traditionnelle (cf. 30, fig. 2), extérieure ou intérieure au procédé et terminé par une entrée (12) et une sortie (13) permettant les connexions de service pour tout type d'installation, chauffage, production de liquide chauffé etc.,...The circuit of the heated liquid is accelerated by a traditional pump (see 30, Fig. 2), external or internal to the process and terminated by an inlet (12) and an outlet (13) allowing the service connections for any type of installation, heating, production of heated liquid etc., ...
L'ensemble du circuit externe de l'invention est alimenté par l'entrée (16).The entire external circuit of the invention is powered by the input (16).
L'invention peut être équipé d'un petit (14) qui par l'apport du liquide support (eau dans ce cas), via (10) (11), chargée en calories permet de produire de manière continue une eau chauffée domestique en sortie (15).The invention can be equipped with a small (14) which by the supply of the liquid carrier (water in this case), via (10) (11), loaded in calories can continuously produce a domestic heated water in output (15).
L'invention est auto régulée par un thermostat mesurant la température de sortie du fluide.The invention is self-regulated by a thermostat measuring the outlet temperature of the fluid.
L'invention, par sa conception, fonctionne en circuit fermé et de ce fait ne dégage aucun déchet, fumée ou autre pollution.The invention, by design, operates in a closed circuit and therefore does not release any waste, smoke or other pollution.
Les calories générées par la friction du gaz et non transférées au fluide, sont récupérées en grande partie lors du retour direct du gaz vers la turbine par une durite réduisant l'énergie nécessaire pour la remise à température du gaz.The calories generated by the friction of the gas and not transferred to the fluid, are largely recovered during the direct return of gas to the turbine by a hose reducing the energy required for the gas temperature reset.
Les applications de l'invention sont particulièrement d'ordre thermique :
- génère un fluide chauffé pour alimenter des installations domestiques ou autres (industrielles).
- est surtout adaptée pour des distributions réalisées avec des tubes de petit diamètre. Elle produit une énergie thermique immédiate ne nécessitant pas de ballon d'accumulation
- ne nécessite pas de prise d'air extérieur ni cheminée.
- ne consomme que de l'énergie électrique.
- generates a heated fluid for supplying domestic or other (industrial) installations.
- is especially suitable for distributions made with small diameter tubes. It produces an immediate thermal energy that does not require a storage tank
- does not require an outside air intake or chimney.
- consumes only electrical energy.
L'invention peut être adaptée pour d'autres secteurs : alimentaire, piscine, production d'eau chaude domestique.The invention can be adapted for other sectors: food, swimming pool, production of domestic hot water.
Cette centrale peut être combinée à un système de production de froid traditionnel par le rajout d'une plaque intermédiaire sur l'échangeur.This plant can be combined with a traditional cold production system by adding an intermediate plate on the exchanger.
Les éléments (19) (20) (21) représentent les composantes de réfrigération à savoir le compresseur (20), le condenseur (21), l'échangeur (19), transmettant les frigories au circuit d'utilisation entrée et sortie (12) et (13). Cette configuration de production de frigories n'est pas adaptée aux installations demandant une production d'un liquide chauffé en permanence car dans ce cas il y a une incompatibilité à utiliser une troisième plaque dans l'échangeur.The elements (19) (20) (21) represent the refrigeration components namely the compressor (20), the condenser (21), the exchanger (19), transmitting the frigories to the input and output utilization circuit (12). ) and (13). This configuration of production of frigories is not suitable for installations requiring production of a permanently heated liquid because in this case there is an incompatibility to use a third plate in the exchanger.
Donc le circuit réfrigérant est monté en externe et contrôlé au niveau entrée et sortie par des vannes à commande électrique (17) et (18).Thus the refrigerant circuit is externally mounted and controlled at the input and output level by electrically operated valves (17) and (18).
