Description

EMISOR DE BAJA TEMPERATURA PARA SISTEMAS DE CALEFACCIÓN YLOW TEMPERATURE ISSUER FOR HEATING SYSTEMS AND
REFRIGERACIÓN OBJETO DE LA INVENCIÓNREFRIGERATION OBJECT OF THE INVENTION
La presente invención, tal y como lo expresa el enunciado de esta memoria descriptiva, se refiere a una emisora de baja temperatura para sistemas de calefacción y refrigeración que tiene por objeto facultar su uso para trabajar con temperaturas bajas sin aumentar considerable¬ mente sus dimensiones Otro objeto de la invención consiste en que el emisor o radiador tenga pocas pérdidas por radiación. ANTECEDENTES DE LA INVENCIÓN Actualmente son conocidos sistemas de calefac¬ ción central, tanto de usos colectivos como individuales, que consisten en la utilización de una caldera que aporta el calor a un fluido caloportador, normalmente agua, la cual es transportada mediante conducciones que cierran el circuito y entre las que se disponen los elementos emiso¬ res, como son radiadores, convectores, suelo radiante, ventilo-convector, o aerotermos .The present invention, as expressed in the description of this specification, refers to a low temperature transmitter for heating and cooling systems that is intended to enable its use to work at low temperatures without considerably increasing its dimensions Other The object of the invention is that the emitter or radiator has low radiation losses. BACKGROUND OF THE INVENTION At present, central heating systems are known, both for collective and individual uses, which consist of the use of a boiler that provides heat to a heat transfer fluid, normally water, which is transported through pipes that close the circuit and among which the emitting elements are arranged, such as radiators, convectors, underfloor heating, fan-convector, or air heaters.
Los radiadores, convectores y suelo radiante se dimensionan para aportar el calor suficiente, en función de su superficie útil, a los locales que deben de calefac- tar. En el caso de emisores tipo ventilo-convector o aerotermos se genera un caudal de aire que aporta un ven¬ tilador accionado por un motor eléctrico.The radiators, convectors and underfloor heating are sized to provide sufficient heat, depending on their useful surface, to the premises that must be heated. In the case of air vent-convector or air-type emitters, an air flow is generated that provides a fan driven by an electric motor.
De todos los emisores citados, el más utiliza¬ do en calefacción doméstica es el radiador de agua, ya sea de chapa de acero, aluminio o fundición. Los emisores tipo radiador y convector ya comentados anteriormente, precisan que la temperatura de fluido sea alta, dimensionándose para valores de 90°C en la conducción de ida y 70°C en la conducción de retorno en los radiadores e incluso más en los convectores. Dentro de los emisores indicados, los únicos que utilizan temperaturas inferiores, son el suelo radiante y los sistemas de ventilación forzada, si bien cabe indicar que los aerotermos suelen utilizar temperatu¬ ras algo altas.Of all the emitters mentioned, the most commonly used in domestic heating is the water radiator, whether made of sheet steel, aluminum or cast iron. The radiator and convector type emitters already mentioned above, require that the fluid temperature be high, being sized for values of 90 ° C in the one-way driving and 70 ° C in the return conduction in the radiators and even more in the convectors. Within the indicated emitters, the only ones that use lower temperatures are the ground radiant and forced ventilation systems, although it should be noted that air heaters usually use somewhat high temperatures.
Por tanto, el uso del suelo radiante, ventilo- convector y aerotermos, que utilizan temperaturas bajas, determina que se consiga un mayor rendimiento en la generación, al mismo tiempo que se disminuyen las pérdidas por radiación y convección del sistema de calefacción. Asimismo se utilizan radiadores convencionales para baja temperatura, en cuyo caso es idóneo dimensionarlos con temperaturas de diseño de 75°C en la conducción de ida y 60°C en la conducción de retorno.Therefore, the use of the radiant floor, fan-convector and air heaters, which use low temperatures, determines that a greater performance in the generation is achieved, at the same time that the radiation and convection losses of the heating system are reduced. Conventional radiators are also used for low temperature, in which case it is ideal to size them with design temperatures of 75 ° C in the one-way driving and 60 ° C in the return conduction.
Como es sabido, los emisores convencionales aportan el calor en función de la diferencia de temperatura existente entre éstos (temperatura media) y el local a calefactar. Este calor es asimismo función de la superficie del emisor. Evidentemente se pueden disminuir las tempera¬ turas de trabajo aumentando las superficies, pero esto obliga a diseñar grandes superficies que ocupan gran parte de las paredes de los locales o casas, lo que constituye un inconveniente. En cualquier caso el emisor pierde el efecto de convección según disminuye la temperatura, quedando únicamente el efecto de radiación, cuando las temperaturas son muy bajas. Pues bien, los emisores con ventilación forzada que trabajan a baja temperatura como es el ventilo- convector o los aerotermos, encarecen la instalación al precisar de un motor eléctrico que los accione, para lo que se precisa realizar la correspondiente instalación eléctrica, aparte del consumo eléctrico que estos tienen, lo que disminuye el rendimiento del sistema de calefacción.As is known, conventional emitters provide heat depending on the difference in temperature between them (average temperature) and the room to be heated. This heat is also a function of the emitter surface. Obviously, working temperatures can be reduced by increasing the surfaces, but this forces to design large surfaces that occupy a large part of the walls of the premises or houses, which constitutes an inconvenience. In any case, the emitter loses the convection effect as the temperature decreases, leaving only the radiation effect, when the temperatures are very low. Well, the emitters with forced ventilation that work at low temperature such as the fan-convector or the air heaters, make the installation more expensive by requiring an electric motor that drives them, for which it is necessary to perform the corresponding electrical installation, apart from the consumption electrical they have, which decreases the performance of the heating system.
Por su lado la instalación de suelo radiante, aunque trabaja a baja temperatura obliga a empotrar en el suelo tuberías de gran recorrido, previo aislamiento del suelo, lo cual encarece grandemente las instalaciones a la vez que crea una inercia en el sistema que no la hace idónea para cierto tipo de climas, como pueden ser los climas suaves.On the other hand, the installation of underfloor heating, although working at a low temperature, forces long-running pipes to be embedded in the ground, prior to ground insulation, which greatly increases the installation of Once it creates an inertia in the system that does not make it suitable for certain types of climates, such as mild climates.
DESCRIPCIÓN DE LA INVENCIÓN Para resolver los inconvenientes anteriormente indicados, la invención consiste en un emisor de baja temperatura para sistemas de calefacción, que además es aplicable en sistemas de refrigeración, que se caracteriza porque cuenta con un ventilador que es accionado por el paso del fluido transmisor del calor o frió, que es impulsado desde la caldera o enfriador, de manera que en el emisor se fuerza la salida del aire por cenvección y una baja emisión por radiación.DESCRIPTION OF THE INVENTION To solve the aforementioned drawbacks, the invention consists of a low temperature emitter for heating systems, which is also applicable in cooling systems, characterized in that it has a fan that is driven by the passage of fluid. transmitter of heat or cold, which is driven from the boiler or cooler, so that the emitter is forced out of the air by cenvection and a low emission by radiation.
El fluido transmisor del calor o frió utiliza- do preferentemente en la invención es el agua.The heat or cold transmitting fluid preferably used in the invention is water.
El hecho de que el emisor del invención consista en un convector forzado, faculta trabajar con bajas temperaturas de impulsión con los grandes ahorros que esto supone, tanto en generación como en distribución. Además, a pesar de ser un convector forzado, no precisa la utilización de un motor eléctrico, de manera que se evita la instalación eléctrica necesaria para alimentarlo, tal y como sucede en los sistemas conven¬ cionales, y además se ahora el consumo eléctrico de este motor.The fact that the emitter of the invention consists of a forced convector, allows working with low driving temperatures with the great savings that this entails, both in generation and distribution. In addition, despite being a forced convector, it does not require the use of an electric motor, so that the electrical installation necessary to power it is avoided, as is the case in conventional systems, and in addition the electrical consumption of This engine
Cabe indicar que aunque las bombas principales de la caldera tendrán un consumo adicional por el trabajo que realizan los ventiladores, este consumo es muy inferior a la suma de los consumos de todos los motores accionados eléctricamente que tendría que soportar la instalación para realizar la ventilación forzada.It should be noted that although the main boiler pumps will have an additional consumption due to the work done by the fans, this consumption is much lower than the sum of the consumption of all electrically driven motors that the installation would have to support to perform forced ventilation. .
Otra característica de la invención consiste en que el eje del ventilador está relacionado con el eje de un rodete que se intercala en la conducción del fluido transmisor de temperatura. El rodete está compuesto por una pluralidad de aletas radiales situadas de manera que al circular el fluido transmisor del calor o frío se desplazan producién¬ dose el giro del eje. Además, el eje del ventilador se relaciona con el eje del rodete a través de un multiplicador de manera que se faculta la variación de velocidad del giro del ventilador, obteniéndose un mayor rendimiento.Another feature of the invention is that the axis of the fan is related to the axis of an impeller that is interspersed in the conduction of the temperature transmitting fluid. The impeller is composed of a plurality of radial fins positioned so that when the heat or cold transmitting fluid circulates, the shaft is rotated. In addition, the axis of the fan is related to the axis of the impeller through a multiplier so that the variation of speed of the rotation of the fan is empowered, obtaining a greater performance.
Todas las características descritas, deter- minan una estructura que puede ser acoplada a un radiador convencional. Ahora bien, existe la posibilidad de fabricar un radiador específico constituido por una carcasa dotada de una cara frontal radiante y una cara trasera aislante. La cara trasera aislante tiene una pared interior de material radiante para aumentar el rendimien¬ to.All the features described determine a structure that can be coupled to a conventional radiator. However, there is the possibility of manufacturing a specific radiator consisting of a housing equipped with a radiating front face and an insulating rear face. The insulating rear face has an inner wall of radiant material to increase performance.
El hecho de utilizar la cara aislante evita pérdidas de potencia del emisor, potencia que se cede a la pared donde se apoya, asimismo se disminuyen las pérdidas por conducción a través de la pared, tanto hacia el exterior, como a los locales vecinos, colindantes en planta o superiores.The fact of using the insulating face avoids losses of power of the emitter, power that is transferred to the wall where it is supported, also the losses by conduction through the wall, both towards the outside, as well as to neighboring, adjoining premises are reduced in plant or superiors.
En la unión del ventilador al rodete se dispone una válvula termostática que impide que gire el ventilador hasta que el fluido transmisor del calor o frío no adquiera una cierta temperatura.At the junction of the fan to the impeller there is a thermostatic valve that prevents the fan from rotating until the heat or cold transmitting fluid does not acquire a certain temperature.
Entre la cara frontal radiante y la trasera aislante se define una cámara en la que se incluye un serpentín de tubo con una pluralidad de aletas . Para realizar las funciones de refrigeración, se sitúa en su parte inferior una bandeja para conden¬ sación.Between the radiating front face and the insulating rear, a chamber is defined in which a tube coil with a plurality of fins is included. To perform the cooling functions, a tray for condensation is placed at the bottom.

DESCRIPCIÓN DE UN EJEMPLO DE REALIZACIÓN DE LA INVENCIÓN A continuación se realiza una descripción de la invención basada en las figuras anteriormente comen- tadas.DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION A description of the invention based on the above-mentioned figures is given below.
La invención consiste en un radiador 1 de baja temperatura, que siendo su instalación similar a la de los radiadores convencionales de calefacción, puede trabajar con bajas temperaturas sin aumentar considerablemente sus dimensiones.The invention consists of a low temperature radiator 1, which being its installation similar to that of conventional heating radiators, can work at low temperatures without considerably increasing its dimensions.
En el radiador 1 se incluye un serpentín 2 unido a un aleteado 5 cuya salida 4 constituye el retorno al circuito de calefacción o refrigeración.Radiator 1 includes a coil 2 connected to a fin 5 whose output 4 constitutes the return to the heating or cooling circuit.
La novedad fundamental de la invención reside en que en la entrada 3 del radiador 1 se expone un rodete 6 cuyo eje 7 se relaciona con el eje de un ventilador 8.The fundamental novelty of the invention is that at the inlet 3 of the radiator 1 an impeller 6 is exposed whose axis 7 is related to the axis of a fan 8.
El eje del rodete 6 está unido a una plurali¬ dad de aletas radiales 11, de manera que el fluido, preferentemente agua, que circula por el circuito de refrigeración o calefacción, al entrar al rodete por la conducción 3, y obligársele a salir por el conducción 3', se produce el desplazamiento angular de las aletas radiales 11, y por tanto de su eje 7.The axis of the impeller 6 is connected to a plurality of radial fins 11, so that the fluid, preferably water, circulating through the cooling or heating circuit, when entering the impeller through the conduction 3, and being forced out of conduit 3 ', angular displacement of the radial fins 11, and therefore of its axis 7, occurs.
El giro del eje 7 se trasmite al eje del ventilador 8, de manera que se obliga a circular el aire en el interior del radiador, tal y como se le ha descrito anteriormente.The rotation of the axis 7 is transmitted to the axis of the fan 8, so that the air inside the radiator is forced to circulate, as described above.
El radiador está constituido por una carcasa determinada por una pared frontal radiante 13 y pared trasera aislante 12, entre las que se crea una cámara de aire en la que se incluyen los elementos descritos ante¬ riormente (rodete, ventilador, serpentín, aleteado 5).The radiator is constituted by a housing determined by a radiant front wall 13 and insulating rear wall 12, among which an air chamber is created in which the elements described above are included (impeller, fan, coil, fin 5) .
La cara interna del aislante 12 está cons¬ tituida por un material radiante 12' para favorecer el funcionamiento del conjunto al conseguir la refracción en el interior de la cámara, obteniéndose un mayor rendimien¬ to.The inner face of the insulator 12 is constituted by a radiant material 12 'to favor the operation of the assembly by achieving refraction inside the chamber, obtaining a higher yield.
En la parte inferior de la carcasa del radiador se han previsto unas aberturas ranuradas 9 que constituyen el medio a través del cual se fuerza la entrada del aire al interior del radiador, aire que es impulsado por el ventilador 8 a lo largo de todo el serpentín 2 para posteriormente salir a través de la abertura 10 prevista en la parte superior de la pared frontal radiante 13, ob- teniéndose así un radiador por convección que funciona en baja temperatura que obtiene un máximo aprovechamiento del rendimiento del sistema de calefacción, al forzarse la circulación del aire, y evitarse con el aislante 12 y reflector 12' de la pared posterior, que la potencia se ceda a la pared donde se apoya el radiador; al mismo tiempo que se disminuyen pérdidas por conducción a través de dicha pared trasera, tanto hacia el exterior como hacia los locales vecinos, colindantes o en plantas superiores.Slotted openings 9 are provided in the lower part of the radiator housing that constitute the means through which the entry of air into the radiator is forced, air that is driven by the fan 8 along the entire coil 2 to subsequently exit through the opening 10 provided in the upper part of the radiant front wall 13, thus obtaining a convection radiator operating at low temperature that obtains maximum use of the heating system's performance, when the air circulation, and avoid with the insulator 12 and reflector 12 'of the rear wall, that the power is transferred to the wall where the radiator rests; at the same time that losses are reduced by conduction through said rear wall, both towards the outside and towards the neighboring, adjacent or on higher floors.
Una particularidad de la invención consiste en que el rodete 6 y ventilador 8, pueden acoplarse a los radiadores ya existentes en el mercado, de manera que aunque este conjunto se aplica preferentemente sobre el radiador descrito, presenta la gran ventaja de que puede ser aplicado sobre cualquier radiador convencional, intercalándose el rodete 6 junto con el ventilador 8 a la entrada de conducción del agua del radiador.A particular feature of the invention is that the impeller 6 and fan 8 can be coupled to the radiators already existing in the market, so that although this assembly is preferably applied on the described radiator, it has the great advantage that it can be applied on any conventional radiator, the impeller 6 being intercalated along with the fan 8 to the conduction inlet of the radiator water
Por tanto, la novedad fundamental de la invención reside en el hecho de incorporar un ventilador 8 que es accionado por el paso del propio agua del circuito de calefacción o refrigeración, al disponerse un rodete en la entrada de conducción del radiador.Therefore, the fundamental novelty of the invention resides in the fact of incorporating a fan 8 that is driven by the passage of the water of the heating or cooling circuit itself, by placing an impeller in the radiator conduction inlet.
Por tanto, la invención presenta la posibili¬ dad de ser aplicada a un radiador específico como el descrito anteriormente, o a cualquier radiador conven- cional.Therefore, the invention presents the possibility of being applied to a specific radiator as described above, or to any conventional radiator.
Para facultar la aplicación de la invención en un circuito de refrigeración, se incluye en el radiador una bandeja en la que se recoge el agua producida en la condensación. Cabe indicar que la unión del eje correspon¬ diente del rodete al eje del radiador, puede realizarse mediante un juego multiplicador para facultar la variación de velocidad del ventilador. Incluso en dicha unión se puede disponer un vulvo termostático que haga los efectos de válvula termostática, de manera que impida que gire el ventilador hasta que la temperatura adquiera un determinado valor.To enable the application of the invention in a refrigeration circuit, a tray is included in the radiator in which the water produced in the condensation is collected. It should be noted that the union of the corresponding axis of the impeller to the axis of the radiator can be carried out by means of a multiplier set to enable the variation of the fan speed. Even in said joint, a thermostatic vulvo can be arranged that acts as a thermostatic valve, so as to prevent the fan from rotating until the temperature acquires a certain value.
Además el ventilador puede incorporar un órgano rozante que crea un pérdida de carga adicional, para favorecer el equilibrado de la instalación. In addition, the fan can incorporate a friction element that creates an additional loss of load, to favor the balance of the installation.
