DESCRIPCIONDESCRIPTION

Acumulador de agua calienteHot water tank

La invencion se refiere a un acumulador de agua caliente rodeado por un aislamiento en union con al menos un modulo hidraulico montado en el para la carga y descarga termicas del acumulador.The invention relates to a hot water accumulator surrounded by an insulation in union with at least one hydraulic module mounted therein for thermal loading and unloading of the accumulator.

Los acumuladores de agua caliente sirven para almacenar ene^a termica. En la mayona de los casos se almacena en ellos agua de calefaccion o sanitaria. Para suministrar energfa termica al acumulador, se encuentra frecuentemente en el acumulador de agua sanitaria un intercambiador de calor en forma de helice que es atravesado por un medio de calentamiento. Otra posibilidad consiste en que se retire de la zona inferior del acumulador de agua sanitaria agua fna, que se calienta en un intercambiador de calor externo y, a continuacion, se suministra de nuevo al acumulador. Si el acumulador de agua caliente contiene agua de calefaccion, entonces, el calor del agua de calefaccion para la preparacion de agua sanitaria debe transferirse al agua sanitaria en un intercambiador de calor. Para ello, por un lado, dentro del acumulador de agua caliente, puede estar dispuesto un intercambiador de calor en forma de helice que es atravesado por agua sanitaria. Otra posibilidad consiste en extraer agua de calefaccion caliente del acumulador de agua caliente y transferir una parte de su energfa termica al agua sanitaria en un intercambiador de calor de placas externo.Hot water accumulators are used to store thermal energy. In the majority of cases, heating or sanitary water is stored in them. In order to supply thermal energy to the accumulator, a heat exchanger in the form of a propeller is frequently found in the domestic water accumulator which is passed through a heating means. Another possibility is that fna water is removed from the lower area of the domestic water accumulator, which is heated in an external heat exchanger and then supplied to the accumulator again. If the hot water tank contains heating water, then the heat of the heating water for the preparation of domestic water must be transferred to the domestic water in a heat exchanger. For this, on the one hand, a heat exchanger in the form of a propeller can be arranged inside the hot water accumulator which is crossed by domestic water. Another possibility is to extract hot heating water from the hot water accumulator and transfer a part of its thermal energy to the domestic water in an external plate heat exchanger.

Frecuentemente, se utilizan modulos hidraulicos para cargar y/o descargar un acumulador de agua caliente. Estos modulos hidraulicos representan una unidad constructiva y contienen, ademas de una carcasa, al menos una bomba de circulacion asf como un intercambiador de calor secundario que, en la mayona de los casos, esta configurado como intercambiador de calor de placas. El intercambiador de calor secundario esta unido mediante dos conexiones con el acumulador de agua caliente, de modo que pueda retirarse o suministrarse agua y, por tanto, pueda introducirse o extraerse calor en el acumulador de agua caliente.Frequently, hydraulic modules are used to charge and / or discharge a hot water cylinder. These hydraulic modules represent a construction unit and contain, in addition to a housing, at least one circulation pump as well as a secondary heat exchanger which, in most cases, is configured as a plate heat exchanger. The secondary heat exchanger is connected by two connections with the hot water cylinder, so that water can be withdrawn or supplied and, therefore, heat can be introduced or extracted into the hot water cylinder.

Segun el estado de la tecnica, se fijan unos modulos hidraulicos al lado exterior de un acumulador de agua caliente por medio de tornillos, a continuacion las tubenas hidraulicas de los modulos hidraulicos se unen con las conexiones del acumulador de agua caliente.According to the state of the art, hydraulic modules are fixed to the outer side of a hot water cylinder by means of screws, then the hydraulic pipes of the hydraulic modules are connected to the connections of the hot water tank.

Por el documento EP 784192 A1 se conoce la conexion de un acumulador de agua caliente con un aparato de calefaccion, en el que en el acumulador de agua caliente estan dispuestos unos carriles de union con la carcasa del aparato de calentamiento y las conexiones hidraulicas, de modo que para la union, el aparato de calentamiento deba introducirse solamente en el carril y atornillarse con las conexiones.From document EP 784192 A1, the connection of a hot water cylinder with a heating device is known, in which in the hot water tank there are arranged connecting rails with the housing of the heating device and the hydraulic connections, of so that for the union, the heating device must only be inserted in the rail and screwed with the connections.

El documento GB 2241564 A muestra un aparato de calentamiento con conexiones prefabricadas para unir con una bomba de circulacion dispuesta fuera de la carcasa de calentamiento asf como una valvula de conmutacion.GB 2241564 A shows a heating apparatus with prefabricated connections for joining with a circulation pump disposed outside the heating housing as well as a switching valve.

La invencion se basa en el problema de simplificar la suspension y fijacion de los modulos hidraulicos en acumuladores de agua caliente y reducir la perdida de calor.The invention is based on the problem of simplifying the suspension and fixing of the hydraulic modules in hot water accumulators and reducing heat loss.

Segun la invencion, esto se resuelve de acuerdo con las particularidades caracterizantes de la reivindicacion independiente 1, sirviendo simultaneamente las tubenas de union hidraulicas como elementos de fijacion.According to the invention, this is solved in accordance with the characterizing particularities of independent claim 1, while simultaneously serving the hydraulic connecting tubenas as fixing elements.

Configuraciones ventajosas de la invencion resultan por las caractensticas de las reivindicaciones subordinadas.Advantageous configurations of the invention result from the characteristics of the dependent claims.

La invencion se explica en detalle ahora con ayuda de las figuras. Muestran aqrn:The invention is explained in detail now with the help of the figures. They show here:

La figura 2, el mismo acumulador de agua caliente con dos modulos hidraulicos en vista frontal (de los modulos hidraulicos), yFigure 2, the same hot water cylinder with two hydraulic modules in front view (of the hydraulic modules), and

La figura 3, la union del acumulador de agua caliente con un modulo hidraulico en una vista en detalle.Figure 3, the union of the hot water cylinder with a hydraulic module in a detailed view.

Las figuras muestran un acumulador de agua caliente 1 con cuatro conexiones hidraulicas 5, 6, 7, 8 a diferente nivel de altura, atravesando las conexiones hidraulicas 5, 6, 7, 8 una pared 4 del acumulador de agua caliente 1 en un lado. El acumulador de agua caliente 1 esta rodeado por un aislamiento 15, presentando el aislamiento 15 unos rebajos en el lugar de las conexiones hidraulicas 5, 6, 7, 8. Las conexiones hidraulicas 5, 6, 7, 8 disponen de roscas en el lado exterior del acumulador de agua caliente. En estas roscas de las conexiones hidraulicas 5, 6, 7, 8 encajan cuatro tubos de conexion 9, 10, 11, 12 y, por tanto, atraviesan el aislamiento 15.The figures show a hot water tank 1 with four hydraulic connections 5, 6, 7, 8 at a different height, through the hydraulic connections 5, 6, 7, 8 a wall 4 of the hot water tank 1 on one side. The hot water tank 1 is surrounded by an insulation 15, the insulation 15 having recesses in place of the hydraulic connections 5, 6, 7, 8. The hydraulic connections 5, 6, 7, 8 have threads on the side outside of the hot water cylinder. In these threads of the hydraulic connections 5, 6, 7, 8 fit four connecting pipes 9, 10, 11, 12 and, therefore, cross the insulation 15.

En el aislamiento 15 del acumulador de agua caliente 1 estan asentados dos modulos hidraulicos 2, 3. Las paredes traseras 16, 17 de los modulos hidraulicos 2, 3 disponen de orificios que rodean los tubos de conexion 9, 10. 11, 12. En el lado de los tubos de conexion 9, 10, 11, 12 alejado del acumulador de agua caliente 1 se encuentran unas roscas exteriores que sirven para fijar al acumulador de agua caliente 1, gracias a unas tuercas correspondientes, las paredes traseras 16, 17 de los modulos hidraulicos 2, 3.In the insulation 15 of the hot water tank 1 two hydraulic modules 2, 3 are seated. The rear walls 16, 17 of the hydraulic modules 2, 3 have holes that surround the connection pipes 9, 10. 11, 12. on the side of the connecting pipes 9, 10, 11, 12 away from the hot water tank 1 are external threads that serve to fix the hot water tank 1, thanks to corresponding nuts, the rear walls 16, 17 of the hydraulic modules 2, 3.

Los tubos de conexion 9, 10, 11, 12 disponen de ranuras radialmente perifericas 13 en el lado dentro de la rosca en el lado vuelto al acumulador, en cada una de las cuales esta dispuesta una junta radial 14.The connecting tubes 9, 10, 11, 12 have radially peripheral grooves 13 on the side inside the thread on the side returned to the accumulator, in each of which a radial joint 14 is arranged.

Para el montaje de los modulos hidraulicos 2, 3 se introducen primero en las ranuras 13 de los tubos de conexion 9, 10, 11, 12 unas juntas radiales 14. A continuacion, los tubos de conexion 9, 10, 11, 12 se enchufan en el aislamiento 15 a traves de las aberturas y se atornillan con las conexiones hidraulicas 5, 6, 7, 8. Las juntas radiales 14 sellan aqu las transiciones de manera estanca al agua. Si los tubos de conexion 9, 10, 11, 12 estan atornillados, entonces estos sobresalen del aislamiento 15 del acumulador de agua caliente 1. Los tubos de conexion 9, 10, 11, 12 disponen, en el lado alejado del acumulador de agua caliente 1, de un diametro mayor que en el lado asociado al acumulador de agua caliente 1. Los modulos hidraulicos 2, 3 se asientan ahora de tal modo que los pasos en las paredes traseras 16, 17 de los modulos hidraulicos 2, 3 estan calados sobre los tubos de conexion 9, 10, 11, 12. Dado que las paredes traseras 16, 17 descansan sobre el diametro mayor de los tubos de conexion 9, 10, 11, 12, se reduce la carga superficial. A continuacion, se atornillan unas tuercas 22 por medio de las roscas exteriores de los tubos de conexion 9, 10, 11, 12, de modo que las paredes traseras 16, 17 de los modulos hidraulicos 2, 3 se presionen en el acumulador de agua caliente 1 y se unan fijamente con este. Finalmente, los tubos de conexion 9, 10, 11, 12 se unen con las bombas 18, 19 y los intercambiadores de calor de placas 20, 21 de los modulos hidraulicos 2, 3.To assemble the hydraulic modules 2, 3, radial joints 14 are first inserted into the grooves 13 of the connecting pipes 9, 10, 11, 12, and then the connecting pipes 9, 10, 11, 12 are plugged in in the insulation 15 through the openings and screwed with the hydraulic connections 5, 6, 7, 8. The radial joints 14 here seal the transitions in a water tight manner. If the connection pipes 9, 10, 11, 12 are screwed, then they protrude from the insulation 15 of the hot water tank 1. The connection pipes 9, 10, 11, 12 have, on the far side of the hot water tank 1, of a diameter larger than on the side associated with the hot water tank 1. The hydraulic modules 2, 3 are now seated so that the passages in the rear walls 16, 17 of the hydraulic modules 2, 3 are open the connection tubes 9, 10, 11, 12. Since the rear walls 16, 17 rest on the largest diameter of the connection tubes 9, 10, 11, 12, the surface load is reduced. Next, nuts 22 are screwed by means of the outer threads of the connecting pipes 9, 10, 11, 12, so that the rear walls 16, 17 of the hydraulic modules 2, 3 are pressed into the water accumulator Warm 1 and join firmly with this. Finally, the connection pipes 9, 10, 11, 12 are connected with the pumps 18, 19 and the plate heat exchangers 20, 21 of the hydraulic modules 2, 3.

El lado secundario del intercambiador de calor de placas 20 del modulo hidraulico 2 se une con un colector solar, de modo que el modulo hidraulico 2 sirva como estacion solar. El lado secundario del intercambiador de calor de placas 21 del modulo hidraulico 3 se une con tubenas de agua sanitaria, de modo que el modulo hidraulico 3 sirva como estacion de agua fresca.The secondary side of the plate heat exchanger 20 of the hydraulic module 2 joins a solar collector, so that the hydraulic module 2 serves as a solar station. The secondary side of the plate heat exchanger 21 of the hydraulic module 3 joins with sanitary water pipes, so that the hydraulic module 3 serves as a fresh water station.

Por tanto, el entubado hidraulico puede utilizarse simultaneamente como elemento de fijacion. En consecuencia, no solo existe una sencilla posibilidad del montaje. Por el contrario, se logra tambien un mejor aislamiento del acumulador de agua caliente 1 dado que, aparte del entubado, no existen otros puentes termicos que atraviesen el aislamiento 15 para la fijacion de los modulos hidraulicos 2, 3 entre el acumulador de agua caliente 1 y el ambiente.Therefore, the hydraulic tubing can be used simultaneously as a fixing element. Consequently, there is not only a simple possibility of assembly. On the contrary, better insulation of the hot water tank 1 is also achieved since, apart from the tubing, there are no other thermal bridges that cross the insulation 15 for fixing the hydraulic modules 2, 3 between the hot water tank 1 and the environment.

En los tubos de conexion 9, 10, 11, 12 que se prolongan, segun una variante que no cae bajo la invencion, puede renunciarse a que las conexiones hidraulicas 5, 6, 7, 8 dispongan de longitudes correspondientes. Para el sellado entre las conexiones hidraulicas 5, 6, 7, 8 y los tubos de conexion 9, 10, 11, 12, pueden utilizarse tambien otros medios de sellado (por ejemplo, canamo o cinta de Teflon).In the connecting pipes 9, 10, 11, 12 which extend, according to a variant that does not fall under the invention, it can be waived that the hydraulic connections 5, 6, 7, 8 have corresponding lengths. For sealing between the hydraulic connections 5, 6, 7, 8 and the connecting pipes 9, 10, 11, 12, other sealing means (for example, canamo or Teflon tape) can also be used.

En lugar de roscas, para la union hidraulica pueden utilizarse tambien acoplamientos rapidos.Instead of threads, quick couplings can also be used for hydraulic connection.
