Abstract
Description
La présente invention concerne une installation de chauffage thermodynamique d'eau chaude sanitaire à capteur enterré. The present invention relates to a thermodynamic heating installation for domestic hot water with buried sensor.
On a déjà proposé des installations de chauffage d'eau chaude sanitaire par pompe à chaleur à capteurs enterrés, celles-ci étant couplées au chauffage des locaux. On a également proposé des chauffe eau thermodynamiques monoblocs utilisant l'air extérieur ou l'air extrait comme sources froides. Sanitary hot water heating systems have already been proposed by heat pump with buried sensors, these being coupled to space heating. One-piece thermodynamic water heaters have also been proposed using outside air or extracted air as cold sources.
L'invention a pour objet une installation de chauffage thermodynamique d'eau sanitaire comportant trois éléments distincts démontables : un réservoir d'eau, un bloc thermodynamique et un capteur enterré. The subject of the invention is a thermodynamic domestic water heating installation comprising three separate removable elements: a water tank, a thermodynamic block and a buried sensor.
On connaît déjà des installations de chauffage d'eau sanitaire par pompe à chaleur dans lesquelles le condenseur est enroulé autour de l'enveloppe de la cuve. Sanitary water heating systems by heat pump are already known in which the condenser is wound around the shell of the tank.
On connaît également des chauffe eau thermodynamiques monoblocs où les composants sont fixés sur la cuve extérieure. Ces installations présentent l'inconvénient de ne pas permettre le démontage de la cuve en cas de corrosion de celle-ci et présentent le désavantage d'être très lourdes, ce qui ne facilite pas les manutentions.There are also known one-piece thermodynamic water heaters where the components are fixed to the external tank. These installations have the disadvantage of not allowing disassembly of the tank in the event of corrosion thereof and have the disadvantage of being very heavy, which does not facilitate handling.
C'est d'une manière générale un but de l'invention de fournir une installation de chauffe eau thermodynamique qui ne présente pas les inconvénients des installations connues. It is generally an object of the invention to provide a thermodynamic water heater installation which does not have the drawbacks of known installations.
Une installation de chauffe eau thermodynamique selon l'invention comporte au moins un capteur enterré horizontalement placé à l'extérieur du local où se situe la cuve et relié au bloc thermodynamique par deux raccords préchargés. A thermodynamic water heater installation according to the invention comprises at least one horizontally buried sensor placed outside the room where the tank is located and connected to the thermodynamic block by two preloaded connections.
Selon une autre caractéristique de l'invention, le bloc thermodynamique est uniquement fixé sur la cuve au moyen d'une bride. According to another characteristic of the invention, the thermodynamic block is only fixed to the tank by means of a flange.
Elle vise en particulier un bloc thermodynamique, caractérisé en ce qu'il comprend un chassis solidaire d'une bride, sur lequel est fixé le compresseur frigorifique et les différents accessoires tel le doigt de gant de l'aquastat et le condenseur fixé sur la bride par l'intermédiaire de deux manchons isolants électriquement le condenseur de la cuve afin de ne pas permettre l'établissement de courants conduisant à une corrosion électrolytique du ballon. La conception du système permet l'utilisation de ballons standards du commerce. It relates in particular to a thermodynamic block, characterized in that it comprises a frame integral with a flange, on which is fixed the refrigeration compressor and the various accessories such as the thermowell of the aquastat and the condenser fixed on the flange by means of two electrically insulating sleeves the condenser of the tank in order not to allow the establishment of currents leading to electrolytic corrosion of the balloon. The design of the system allows the use of standard commercial balloons.
L'utilisation de la terre comme source froide permet de garantir de bonnes performances quelle que soit la saison. Le capteur évaporateur extérieur est constitué d'au moins une couronne de tube de faible diamètre (10 mm par exemple) et d'une longueur de l'ordre de 60 mètres, la couronne est placée en tranchée dans la terre à une profondeur moyenne de 60 cm environ. Le tube sera réalisé en cuivre ou en aluminium, éventuellement plastifié, mais pourra être réalisé en plastique. Aux extrémités du tube sont fixés des raccords mâle et femelle dont l'un est équipé d'un orifice de tirage au vide et de charge. Ces raccords seront raccordés au bloc thermodynamique. Toute la portion de capteur non située en terre, sera calorifugée afin d'éviter les condensations. The use of earth as a cold source guarantees good performance whatever the season. The outdoor evaporator sensor consists of at least one small diameter tube crown (10 mm for example) and a length of the order of 60 meters, the crown is placed in a trench in the ground at an average depth of 60 cm approximately. The tube will be made of copper or aluminum, possibly plasticized, but may be made of plastic. Male and female fittings are attached to the ends of the tube, one of which is fitted with a vacuum and charge port. These fittings will be connected to the thermodynamic block. The entire sensor portion not located in the ground will be insulated to avoid condensation.
L'invention sera bien comprise par la description qui suit faite à titre d'exemple et en référence aux dessins annexés dans lesquels: La figure 1 est un schéma d'une installation selon l'invention. The invention will be better understood from the following description given by way of example and with reference to the accompanying drawings in which: FIG. 1 is a diagram of an installation according to the invention.
. La figure 2 est le détail de la bride du bloc thermodynamique destinée à être
raccordée sur la bride ce la cuve.. Figure 2 is the detail of the flange of the thermodynamic block intended to be
connected to the flange that the tank.
Une installation selon l'invention figure 1 comporte un capteur évaporateur extérieur constitué d'au moins une couronne de tube (10) enterré à l'extérieur dans le sol. Ce capteur sera constitué de tube cuivre ou aluminium (éventuellement plastifiés) ou de plastique d'une longueur de l'ordre de 60 mètres placé en tranchée à une profondeur de l'ordre de 60 cm ou il prélèvera la chaleur de la terre. Le fluide frigorigène liquide à basse pression pénètre dans le capteur par l'intermédiaire d'un raccord (23) de type operculable ou auto-obturable. Une valve placée sur le raccord permettra le tirage au vide et le remplissage en fluide du capteur. La chaleur prélevée dans la terre va permettre de vaporiser le fluide frigorigène dans le capteur (10). La vapeur formée se dirige vers le raccord (11) puis vers le raccord (12) de type operculables ou auto-obturables. La vapeur se dirige ensuite vers le compresseur frigorifique (13) qui comprime le gaz dans le condenseur (19). La chaleur de condensation des vapeurs de fluide frigorigène est cédée à l'eau du ballon qui circule de bas en haut par convection naturelle. Le liquide frigorigène formé est déshydraté et stocké dans le petit réservoir (20) puis détendu dans le détendeur (21) avant de se diriger vers le raccord (22) pour recommencer un nouveau cycle. Le détendeur (21) pourra être du type thermostatique ou constitué d'un tube capillaire ou d'un diaphragme. Le compresseur (13) est commandé par un aquastat (17) dont le bulbe se situe à l'intérieur du doigt de gant (18). Le doigt de gant (18) est installé juste au dessus du condenseur (19) à l'intérieur du ballon, il permet de transmettre à l'aquastat (17) les informations concernant la température de l'eau dans la cuve (15) et dans la partie basse de celle-ci, ce qui permet de maintenir la température de l'eau dans la cuve à 55"C environ. Le condenseur (19), placé en partie basse de la cuve (15) assure le chauffage de l'eau froide (EF) pénétrant par l'orifice (24) lorsqu'il y a un puisage d'eau chaude (ES) par l'orifice (25). Lorsque la température au doigt de gant est atteinte, laquastat (17) met à l'arrêt le compresseur (13). La cuve (15) est revêtue à l'extérieur d'un calorifuge permettant de limiter les pertes thermiques du ballon d'eau chaude. Un capot (16), en polyester stratifié par exemple, fixé sur le chassis (14), assurera la protection du bloc thermodynamique ainsi que l'esthétique du système. La cuve sera équipée en partie basse, sur une bride, d'anodes solubles en magnésium (26) afin d'éviter les corrosions. An installation according to the invention in FIG. 1 comprises an outdoor evaporator sensor made up of at least one tube ring (10) buried outside in the ground. This sensor will be made of copper or aluminum tube (possibly plasticized) or plastic with a length of the order of 60 meters placed in a trench at a depth of the order of 60 cm or it will take the heat from the earth. The low pressure liquid refrigerant enters the sensor via a sealable or self-sealing type connection (23). A valve placed on the connector will allow vacuuming and filling of the sensor with fluid. The heat taken from the earth will vaporize the refrigerant in the sensor (10). The vapor formed goes to the fitting (11) then to the fitting (12) of the sealable or self-sealing type. The steam then goes to the refrigeration compressor (13) which compresses the gas in the condenser (19). The heat of condensation of the refrigerant vapors is transferred to the water in the tank, which circulates from bottom to top by natural convection. The refrigerant formed is dehydrated and stored in the small tank (20) then expanded in the pressure reducer (21) before heading to the fitting (22) to start a new cycle. The regulator (21) may be of the thermostatic type or consist of a capillary tube or a diaphragm. The compressor (13) is controlled by an aquastat (17), the bulb of which is located inside the thermowell (18). The thermowell (18) is installed just above the condenser (19) inside the tank, it makes it possible to transmit to the aquastat (17) the information concerning the temperature of the water in the tank (15) and in the lower part thereof, which keeps the temperature of the water in the tank at around 55 "C. The condenser (19), placed in the lower part of the tank (15) ensures the heating of cold water (EF) entering through the orifice (24) when there is a hot water draw (ES) through the orifice (25). When the temperature of the thermowell is reached, the laquatat (17 ) switches off the compressor (13). The tank (15) is coated on the outside with a heat-insulating material to limit the thermal losses of the hot water tank. A cover (16), in polyester laminated by example, fixed on the chassis (14), will ensure the protection of the thermodynamic block as well as the aesthetics of the system. The tank will be equipped in the lower part, on a flange, with soluble anodes in ma gnesium (26) to prevent corrosion.
Dans une installation selon l'invention, la figure 2 est le détail de la bride du bloc thermodynamique destinée à être raccordée sur la bride ce la cuve. Le chassis (14) sur lequel sont fixés les composants comme le compresseur, est soudé sur la bride circulaire (31). Cette bride sera boulonnée sur la bride du ballon d'eau chaude par les vis (32) avec interposition d'un joint d'étanchéité. Le doigt de gant (18) est soudé au passage de la bride circulaire (31). Il permet d'introduire le bulbe (33) de l'aquastat (17) qui comporte un capillaire de liaison (34). Le condenseur (19) sera constitué d'un serpentin en cuivre étamé dont les entrées (35) et sortie (36) seront fixées sur la bride au moyen de joints étanches (38) et (39) isolants électriquement le condenseur de la bride. Les épaulements (37) sont solidaires du condenseur (19), des écrous (40) permettent la fixation étanche du condenseur (19) sur la bride (31). In an installation according to the invention, Figure 2 is the detail of the flange of the thermodynamic block intended to be connected to the flange that the tank. The chassis (14) on which the components such as the compressor are fixed, is welded to the circular flange (31). This flange will be bolted to the flange of the hot water tank by the screws (32) with the interposition of a seal. The thermowell (18) is welded to the passage of the circular flange (31). It allows the bulb (33) of the aquastat (17) to be introduced, which comprises a connecting capillary (34). The condenser (19) will consist of a tinned copper coil whose inlets (35) and outlet (36) will be fixed to the flange by means of tight seals (38) and (39) electrically insulating the condenser from the flange. The shoulders (37) are integral with the condenser (19), nuts (40) allow the sealed fixing of the condenser (19) on the flange (31).
Le condenseur (19) pourra être du type à simple enveloppe ou à double enveloppe.The condenser (19) may be of the single envelope or double envelope type.
Le fluide frigorigène de travail du chauffe eau thermodynamique pourra être un fluide pur tel le propane ou le HFC R-134a, mais pourra également être un mélange zéotropique de fluides. The working refrigerant of the thermodynamic water heater may be a pure fluid such as propane or HFC R-134a, but may also be a zeotropic mixture of fluids.
L'invention permet de nombreuses applications en remplacement des chauffe eau traditionnels dans les habitations neuves ou existantes permettant d'assurer de très importantes économies d'énergie. L'installation se limite au percement du mur extérieur, afin de passer les deux extrémités du tube du capteur enterré (10), à la fixation du bloc thermodynamique sur la cuve , à son raccordement électrique et à l'enfouissement du capteur. The invention allows numerous applications to replace traditional water heaters in new or existing dwellings, thereby ensuring very significant energy savings. The installation is limited to the drilling of the external wall, in order to pass the two ends of the buried sensor tube (10), to the fixing of the thermodynamic block on the tank, to its electrical connection and to the burial of the sensor.
