Description

DESCRIPCIÓN  DESCRIPTION
Difusor- inductor de aire para sistemas de climatización. Objeto de la invención Air diffuser-inductor for air conditioning systems. Object of the invention
La invención se refiere a un difusor- inductor de aire para sistemas de climatización, aplicable como elemento terminal en diversos sistemas, por ejemplo sistemas de volumen de aire variable, y que presenta unas características que permiten impulsar aire frío y aire caliente a la vez desde la misma unidad terminal de impulsión, sin causar perturbaciones higrotérmicas en la zona tratada. The invention relates to an air diffuser-inductor for air conditioning systems, applicable as a terminal element in various systems, for example variable air volume systems, and which has characteristics that allow cold air and hot air to be boosted from both the same drive terminal unit, without causing hygrothermal disturbances in the treated area.
Campo de aplicación de la invención. Field of application of the invention.
Esta invención es aplicable en sistemas de climatización y principalmente en sistemas integrales de control de ambiente por zona. This invention is applicable in air conditioning systems and mainly in integral environmental control systems by zone.
Antecedentes de la invención. Background of the invention.
Actualmente son conocidos los difusores de aire empleados en sistemas de climatización, para el suministro de aire a la estancia a tratar o acondicionar. The air diffusers used in air conditioning systems are currently known for the supply of air to the room to be treated or conditioned.
Estos difusores disponen en una cámara o plenum provisto de al menos un cuello de conexión de una entrada de aire primario; y una salida de aire que suministra en aire entrante hacia el interior de una zona o estancia a tratar. These diffusers have in a chamber or plenum provided with at least one connecting neck of a primary air inlet; and an air outlet that supplies incoming air into an area or room to be treated.
El aire es suministrado por el difusor a una temperatura determinada, generalmente controlada mediante un termostato; sin embargo estos difusores no resultan especialmente adecuados en el acondicionamiento térmico de estancias con zonas con diferentes temperaturas; como ocurre en estancias con porciones de fachada acristalada. En estos casos la zona próxima a la fachada es más fría o más caliente que el resto de la estancia, dependiendo de la época del año. Mediante el suministro de aire a la misma temperatura, no se consigue una homogeneización de la temperatura para toda la estancia y se mantienen las diferencias de temperatura en diferentes zonas, lo que origina la existencia de espacios inutilizables principalmente en zonas próximas a la fachada acristalada, o más sensibles a los cambios de temperatura exterior. The air is supplied by the diffuser at a certain temperature, generally controlled by a thermostat; however, these diffusers are not particularly suitable in the thermal conditioning of rooms with areas with different temperatures; as it happens in rooms with portions of glazed façade. In these cases the area near the facade is colder or hotter than the rest of the room, depending on the time of year. By supplying air at the same temperature, temperature homogenization is not achieved for the entire room and temperature differences are maintained in different areas, resulting in the existence of unusable spaces mainly in areas close to the glazed facade, or more sensitive to changes in outside temperature.
Actualmente, para poder realizar esta doble función, se requiere la instalación de dos sistemas diferentes. Currently, in order to perform this double function, the installation of two different systems is required.
Descripción de la invención Description of the invention
Este difusor- inductor presenta unas características adecuadas para instalarse preferentemente sobre los huecos acristalados de fachada o zonas sensibles a los cambios de temperatura exterior y a realizar un doble tratamiento de la zona a climatizar con un único dispositivo; tratando por un lado las cargas térmicas que proviene del exterior, y por otro lado, un acondicionamiento del local. This diffuser inductor has suitable characteristics to be installed preferably on the glazed hollows of the façade or areas sensitive to changes in outside temperature and to perform a double treatment of the area to be heated with a single device; treating on the one hand the thermal loads that come from the outside, and on the other hand, a conditioning of the premises.
Ambas tratamientos pueden realizarse de forma independiente debido al patrón de flujo de aire proporcionado por el difusor- inductor. Both treatments can be performed independently due to the air flow pattern provided by the diffuser-inductor.
Este difusor- inductor de aire para sistemas de climatización; comprendiendo un plenum provisto de al menos un cuello de conexión de una entrada de aire primario; y al menos una salida de aire hacia una zona o estancia a tratar; está caracterizado porque el plenum comprende interiormente una primera cámara y una segunda cámara, separadas, y dispuestas entre una zona común de entrada de aire y unos respectivos elementos de salida de aire hacia la zona o estancia a tratar. Dicha segunda cámara comprende una microbatería por la que circula un líquido calorportador que aporta la energía térmica necesaria para calentar el aire que pasa por dicha segunda cámara y por el correspondiente elemento de salida, de modo que el difusor- inductor permite suministrar simultáneamente aire frío, por los elementos de salida de aire correspondientes a la primera cámara, y aire caliente, por el elemento de salida de aire correspondiente a la segunda cámara. Con estas características el difusor- inductor de la invención presenta frente a las opciones existentes en el mercado, una ventaja importante consistente en la posibilidad de poder impulsar aire en tres ciclos de funcionamiento diferentes con un patrón de flujo de caudal de aire variable y temperatura variable: a) Aire frío (temperatura inferior a la del ambiente) con caudal y temperatura variable. b) Aire caliente (temperatura superior a la del ambiente) con caudal y temperatura variable. c) Aire frío y aire caliente (temperaturas inferiores y superiores a la del ambiente) con caudal y temperatura variable. This air diffuser-inductor for air conditioning systems; comprising a plenum provided with at least one connecting neck of a primary air inlet; and at least one air outlet to an area or room to be treated; It is characterized in that the plenum internally comprises a first chamber and a second chamber, separated, and arranged between a common air inlet zone and respective air outlet elements towards the area or room to be treated. Said second chamber comprises a micro-battery through which a heat-carrying liquid circulates that provides the thermal energy necessary to heat the air that passes through said second chamber and the corresponding outlet element, so that the diffuser inductor allows to simultaneously supply cold air, by the air outlet elements corresponding to the first chamber, and hot air, by the air outlet element corresponding to the second chamber. With these characteristics, the diffuser-inducer of the invention has an important advantage over the options available on the market, which is the possibility of being able to propel air in three different operating cycles with a flow pattern of variable air flow and variable temperature : a) Cold air (lower than ambient temperature) with variable flow and temperature. b) Hot air (higher than ambient temperature) with variable flow and temperature. c) Cold air and hot air (temperatures below and above the ambient temperature) with variable flow and temperature.
Según la invención el difusor- inductor de aire comprende entre la primera cámara y la segunda cámara una capa de material aislante termoacústico, adecuado para evitar el intercambio de energía entre sus respectivos elementos de salida de aire. According to the invention, the air diffuser-inducer comprises between the first chamber and the second chamber a layer of thermoacoustic insulating material, suitable for preventing the exchange of energy between their respective air outlet elements.
La primera cámara comprende, por encima de los correspondientes elementos de salida, una chapa perforada dimensionada convenientemente para provocar en dicha primera cámara una pérdida de carga igual a la producida por la microbatería en la segunda cámara; de modo que los elementos de salida de aire suministran proporciones iguales del total del aire primario procedente de la entrada y producen en el aire de impulsión un efecto inductivo que favorece la separación, sin intercambio térmico entre ellas, de las corrientes o venas de aire suministradas por dichos elementos de salida. Según la invención, los elementos de salida de aire de la primera y la segunda cámara están montados en la parte inferior de la unidad, encontrándose el elemento de salida de aire correspondiente a la segunda cámara orientado verticalmente hacia la zona inferior, y los elementos de salida de aire correspondientes a la primera cámara orientados hacia la zona inferior con un ángulo variable entre el 15° a 60° respecto a la vertical y en dirección divergente respecto al elemento de salida de aire de la segunda cámara. The first chamber comprises, above the corresponding output elements, a perforated sheet suitably sized to cause in said first chamber a load loss equal to that produced by the microbattery in the second chamber; so that the air outlet elements provide equal proportions of the total primary air coming from the inlet and produce an inductive effect in the supply air that favors the separation, without thermal exchange between them, of the air currents or veins supplied for these output elements. According to the invention, the air outlet elements of the first and the second chamber are mounted in the lower part of the unit, the air outlet element corresponding to the second chamber being oriented vertically towards the lower zone, and the elements of air outlet corresponding to the first chamber facing the lower zone with a variable angle between 15 ° to 60 ° with respect to the vertical and in divergent direction with respect to the air outlet element of the second chamber.
Mediante estas características, al instalar el difusor - inductor sobre los huecos acristalados de fachada, de forma que el elemento de salida de la segunda cámara sea el más próximo a la fachada o superficie acristala, la invención consigue diversas ventajas en las zonas tratadas frente a las soluciones convencionales existentes en el mercado: - Reducir los espacios inutilizables próximos a las zonas frías o calientes (zona fachada acristalada). By means of these characteristics, by installing the diffuser-inductor on the glazed hollows of the facade, so that the output element of the second chamber is the closest to the facade or glazed surface, the invention achieves several advantages in the areas treated against Conventional solutions on the market: - Reduce unusable spaces near hot or cold areas (glazed facade area).
- Homogenizar la temperatura radiante asimétrica en la zona tratada, logrando un mayor confort de los espacios disponibles en el local. - Homogenize the asymmetric radiant temperature in the treated area, achieving greater comfort of the spaces available in the premises.
- Disminuir la diferencia de temperatura entre la zona próxima a una pared fría o caliente de la fachada y el interior del local. - Reduce the temperature difference between the area near a cold or hot wall of the facade and the interior of the premises.
- Suministrar la cantidad de aire frío y/o caliente que necesita cada zona del local. Mediante la regulación de sus flujos de aire con el control del difusor- inductor, permite entregar a cada zona sólo la energía que necesita. El decremento de energía necesaria en una zona se transforma en incremento de energía para otra zona. El cuello de conexión de la entrada de aire primario al plenum dispone en su interior de una compuerta de regulación de caudal compuesta por una chapa perforada móvil, sujeta con un eje central. - Supply the amount of cold and / or hot air needed by each area of the premises. By regulating its air flows with the diffuser-inductor control, it allows to deliver to each zone only the energy it needs. The decrease in energy required in one zone is transformed into an increase in energy for another zone. The connection neck of the primary air inlet to the plenum has inside a flow regulation gate composed of a mobile perforated plate, fastened with a central axis.
En función de los requerimientos de aislamiento de la estancia en la que se vaya a instalar el difusor- inductor, el plenum puede comprender en su superficie interior un aislante acústico. Depending on the insulation requirements of the room in which the diffuser inductor is to be installed, the plenum may comprise an acoustic insulator on its inner surface.
Estas y otras características de la invención se comprenderán con mayor facilidad a la vista de un ejemplo de realización. Descripción de las figuras. These and other features of the invention will be more readily understood in view of an exemplary embodiment. Description of the figures.

Realización preferente de la invención Preferred Embodiment of the Invention
El difusor- inductor mostrado en la figura 1 , comprende una entrada (1) de aire primario conectada al plenum (3) mediante un cuello (2) de conexión. The diffuser-inductor shown in Figure 1, comprises a primary air inlet (1) connected to the plenum (3) by means of a connecting neck (2).
El plenum comprende interiormente de una primera cámara (6) provista interiormente de unos elementos de salida de aire (10, 11 ), y de una segunda cámara (7) separada de la anterior y provista inferiormente de un elemento de salida (9) de aire. The plenum comprises internally of a first chamber (6) internally provided with air outlet elements (10, 11), and of a second chamber (7) separated from the previous one and provided inferiorly with an outlet element (9) of air.
La primera (6) y la segunda cámara (7) están dispuestas entre una zona común de entrada de aire y los respectivos elementos de salida de aire (10, 11 ) y (9) hacia la zona o estancia a tratar; saliendo aire de forma proporcional por los elementos de salida (9, 10 y 11 ). La proporcionalidad de aire a salir por cada elemento de salida (9, 10 y 11 ) es un 33% respecto al 100% de aire que entra por el cuello de conexión (1 ). En la segunda cámara (7) hay instalada una microbatería (5) por cuyo interior fluye un líquido calorportador que tiene la función de aportar, en régimen de calor, la energía térmica necesaria para calentar sólo el aire que pasa por el elemento de salida (9) y así permitir que un mismo difusor- inductor suministre aire frió y caliente a la vez. The first (6) and the second chamber (7) are arranged between a common air inlet zone and the respective air outlet elements (10, 11) and (9) towards the area or room to be treated; air coming out proportionally through the outlet elements (9, 10 and 11). The proportionality of air to be expelled by each outlet element (9, 10 and 11) is 33% with respect to 100% of air entering through the connection neck (1). In the second chamber (7) a microbattery (5) is installed through which a heat-carrying liquid flows which has the function of providing, in a heat regime, the thermal energy necessary to heat only the air that passes through the outlet element ( 9) and thus allow the same diffuser-inductor to supply hot and cold air at the same time.
La primera cámara (6) dispone una chapa perforada (4) que provoca la misma pérdida de carga que la microbatería en la segunda cámara, consiguiendo de este modo una distribución uniforme de aire entre los tres elementos de salida de aire, a la vez que garantiza la proporcionalidad del aire en un 33 % en cada elemento. The first chamber (6) has a perforated plate (4) that causes the same pressure loss as the microbattery in the second chamber, thus achieving a uniform distribution of air between the three air outlet elements, while guarantees the proportionality of the air by 33% in each element.
El caudal de aire que pasa por el difusor- inductor se puede variar desde 0% hasta 130% de su valor nominal. The air flow through the diffuser inductor can be varied from 0% to 130% of its nominal value.
En el elemento de salida (9) la temperatura de impulsión puede variar entre un valor de 10°C. hasta 50°C; mientras la temperatura que pasa por los elementos de salida (10 y 11 ) sea constante y diferente con un valor de temperatura menor o igual al valor de temperatura en el elemento de salida (9). In the outlet element (9) the flow temperature may vary between a value of 10 ° C. up to 50 ° C; while the temperature passing through the output elements (10 and 11) is constant and different with a temperature value less than or equal to the temperature value in the output element (9).
Como conjunto el difusor- inductor puede impulsar aire con diferentes temperaturas de forma simultánea As a whole, the diffuser-inductor can drive air with different temperatures simultaneously
Los tres elementos de salida de aire (9, 10 y 11 ), montados en la parte inferior del difusor- inductor, discurren a lo largo del mismo. The three air outlet elements (9, 10 and 11), mounted on the bottom of the diffuser-inductor, run along it.
Como se puede observar en la figura 2, el elemento de salida (9) de la segunda cámara (7) impulsa una vena de aire (33% del caudal de aire total) con un ángulo en vertical que discurre próxima a cara interior de la fachada acristalada (F) del edificio, barriendo la misma con un flujo de aire. As can be seen in Figure 2, the outlet element (9) of the second chamber (7) drives an air vein (33% of the total air flow) with a vertical angle that runs close to the inner face of the glazed facade (F) of the building, sweeping it with an air flow.
Los otros dos elementos de salida (10 y11 ), correspondientes a la primera cámara (6) impulsan el aire restante (66% del caudal de aire total) mediante dos venas con un ángulo variable entre el 15° a 60°, hacia el interior del zona tratada de una estancia (E), permitiendo así el ajuste de la penetración de la vena y la altura de montaje del conjunto difusor- inductor. The other two outlet elements (10 and 11), corresponding to the first chamber (6) propel the remaining air (66% of the total air flow) through two veins with a variable angle between 15 ° to 60 °, inwards from the area treated of a room (E), thus allowing the adjustment of the penetration of the vein and the mounting height of the diffuser-inductor assembly.
Los elementos pueden funcionar de forma independiente, variando la temperatura de impulsión y el caudal. The elements can operate independently, varying the flow temperature and flow rate.
En la salida de los tres elementos de salida (9,10 y 11 ) se produce un fuerte efecto inductivo con el aire de impulsión. Por ello, las tres venas de aire se separan sin permitir intercambio térmico entre ellas. At the output of the three output elements (9,10 and 11) there is a strong inductive effect with the supply air. Therefore, the three air veins separate without allowing thermal exchange between them.
Como se observa en la figura 1 el cuello (2) de conexión con la entrada (1 ) de aire primario comprende compuerta (21 ) de regulación de caudal compuesta por una chapa perforada móvil, sujeta por un eje central (22) de accionamiento. La primera y la segunda cámara (6, 7) están separadas por un material aislante termoacústico (12) que evita el intercambio de energía entre los tres elementos de salida (9, 10 y 11). As can be seen in figure 1, the neck (2) for connection to the primary air inlet (1) comprises a flow regulation gate (21) composed of a mobile perforated plate, held by a central drive shaft (22). The first and second chamber (6, 7) are separated by a thermoacoustic insulating material (12) that prevents the exchange of energy between the three output elements (9, 10 and 11).
En el ejemplo mostrado y según la necesidad acústica del local o estancia a tratar se instala en el interior del plenum un aislante acústico (8). In the example shown and according to the acoustic need of the room or room to be treated, an acoustic insulator (8) is installed inside the plenum.
Para su comercialización, la longitud de difusor- inductor es variable desde 300 mm. hasta 1800 mm. por pieza; con la posibilidad de acoplar varias piezas en serie.
