Description

DESCRIPCIÓN  DESCRIPTION
Título. Puerta isotérmica de doble lona. Objeto de la invención. Title. Isothermal double canvas door. Object of the invention.
El objeto de la presente invención es una puerta isotérmica de doble lona que comprende un marco de soporte destinado a montarse en una zona de paso entre dos recintos y en el que se encuentran montados unos medios de accionamiento de unas lonas entre una posición de apertura y una posición de cierre, definiendo dichas lonas entre sí, una cavidad intermedia dispuesta entre los dos recintos a separar y aislar térmicamente. The object of the present invention is a double-canvas isothermal door comprising a support frame intended to be mounted in a passageway between two enclosures and in which means for actuating canvases between an opening position and a closed position, said canvases defining each other, an intermediate cavity arranged between the two enclosures to be separated and thermally insulated.
Estado de la técnica. State of the art
Actualmente existen en el mercado diferentes tipos de puertas isotérmicas destinadas a establecer una separación entre dos recintos a diferentes temperaturas. Currently there are different types of isothermal doors on the market intended to establish a separation between two enclosures at different temperatures.
Un ejemplo típico son las puertas de acceso a cámaras frigoríficas o recintos refrigerados. Algunas de las puertas conocidas y utilizadas con ésta finalidad son las puertas de doble lona con cámara de aire central, que comprenden un marco, provisto de guías laterales para el desplazamiento de las lonas entre una posición de apertura y una posición de cierre, y unos medios motrices para el desplazamiento de dichas lonas entre las posiciones de apertura y de cierre del hueco de paso de la puerta. A typical example is the access doors to cold rooms or refrigerated rooms. Some of the doors known and used for this purpose are double canvas doors with central air chamber, which comprise a frame, provided with lateral guides for the movement of the canvases between an opening position and a closing position, and some driving means for moving said canvases between the opening and closing positions of the door opening.
En la posición de cierre de la puerta las dos lonas definen una cavidad intermedia, entre los dos recintos delimitados. Dicha cavidad se llena de aire y, en algunos casos, incorpora unos medios de introducción de aire. In the closed position of the door the two canvases define an intermediate cavity, between the two enclosures delimited. Said cavity is filled with air and, in some cases, incorporates air introduction means.
i Como es sabido, el aire es uno de los mejores aislantes térmicos, ya que tiene un coeficiente de conductividad muy bajo; con la ventaja de que es un producto abundante en la naturaleza y no tóxico, por lo que es una buena opción para ser utilizado como aislante. i As is known, air is one of the best thermal insulators, since it has a very low conductivity coefficient; with the advantage that it is an abundant product in nature and non-toxic, making it a good option to be used as an insulator.
Sin embargo, de forma natural el aire está cargado de iones positivos, lo que provoca una excitación de las partículas que intentan volver a la neutralidad. Para ello dichas partículas de aire aumentan el movimiento, generando pequeñas corrientes de aire, que permite, por la ley de Fourier, la transferencia de calor entre dos zonas. However, naturally the air is charged with positive ions, which causes an excitation of the particles trying to return to neutrality. For this, said air particles increase the movement, generating small air currents, which allows, by Fourier's law, the transfer of heat between two zones.
El titular de la presente invención desconoce la existencia en el mercado de puertas isotérmicas del tipo descrito anteriormente y que permitan incrementar el aislamiento térmico proporcionado por el aire contenido en la cavidad intermedia de la puerta cuando ésta se encuentra en la posición de cierre. The holder of the present invention is unaware of the existence in the market of isothermal doors of the type described above and that allow increasing the thermal insulation provided by the air contained in the intermediate cavity of the door when it is in the closed position.
Descripción de la invención La puerta isotérmica de doble lona objeto de esta invención, siendo del tipo de las descritas en el apartado anterior, presenta unas particularidades constructivas orientadas a incrementar el asilamiento proporcionado por el aire contenido en la cavidad intermedia, delimitada por las dos lonas y por el marco de la puerta, y dispuesta entre los recintos a separar térmicamente cuando esta puerta se encuentra en la posición de cierre. DESCRIPTION OF THE INVENTION The double-canvas isothermal door object of this invention, being of the type described in the previous section, has constructive features aimed at increasing the isolation provided by the air contained in the intermediate cavity, delimited by the two canvases. and by the door frame, and arranged between the enclosures to be thermally separated when this door is in the closed position.
La solución propuesta en la presente invención consiste en incorporar un dispositivo ionizador del aire contenido en la cavidad intermedia, de la puerta isotérmica, para cargarlo eléctricamente de forma negativa. The solution proposed in the present invention consists in incorporating an ionizing device of the air contained in the intermediate cavity, of the isothermal door, to charge it electrically in a negative way.
Con la incorporación del mencionado dispositivo ionizador se consigue en la cámara intermedia un ambiente con un mayor número de cargas negativas, respecto a los recintos externos, que naturalmente, suelen estar cargados de forma positiva y generan una convección natural no deseada en su intento de volver a su neutralidad. With the incorporation of the aforementioned ionizing device, an environment with a greater number of negative charges is achieved in the intermediate chamber, with respect to the external enclosures, which naturally are usually charged positive and generate an unwanted natural convection in its attempt to return to neutrality.
Con la ionización del aire de la cavidad intermedia, mediante un dispositivo ionizador, se consigue minimizar la convección natural, obteniendo un ambiente más estanco, ya que la carga negativa del aire contenido entre las dos lonas de la puerta provoca una atracción de los iones cargados positivamente, del exterior de la cavidad intermedia, minimizando así la recirculación del aire cercano a las lonas e incrementando consiguientemente el efecto aislante de la cavidad intermedia de la puerta isotérmica.  With the ionization of the air in the intermediate cavity, by means of an ionizing device, it is possible to minimize the natural convection, obtaining a more tight environment, since the negative charge of the air contained between the two canvases of the door causes an attraction of the charged ions positively, outside the intermediate cavity, thus minimizing the recirculation of the air near the canvases and consequently increasing the insulating effect of the intermediate cavity of the isothermal door.

Realización preferida de la invención. Preferred embodiment of the invention.
La puerta isotérmica representada en la figura 1 comprende un marco (1 ) destinado a montarse en una zona de paso, entre dos recintos a diferentes temperaturas, disponiendo dicho marco (1 ), en sus montantes verticales, de unas parejas de guías verticales (21 , 22) para dirigir las dos lonas de cierre (31 , 32) que se desplazan simultáneamente en dirección vertical hacia una posición de apertura, o una posición de cierre, del hueco delimitado por el marco (1 ). The isothermal door shown in Figure 1 comprises a frame (1) intended to be mounted in a passage area, between two enclosures at different temperatures, said frame (1), in its vertical uprights, having pairs of vertical guides (21, 22) to direct the two closing canvases (31, 32) which move simultaneously in the vertical direction towards an opening position, or a closing position, of the gap delimited by the frame (1).
La puerta comprende superiormente unos tambores (41 , 42) accionados por un elemento motor (4) encargado de provocar el enrollado y desenrollado de las lonas (31 , 32) sobre los respectivos tambores (41 , 42). The door comprises superiorly drums (41, 42) driven by a motor element (4) responsible for causing the winding and unwinding of the canvases (31, 32) on the respective drums (41, 42).
Las lonas (31 , 32) definen entre sí una cavidad intermedia (5) que se llena con aire, preferentemente caliente, proyectado a través de unos puntos de ventilación (1 1 ) definidas en los montantes verticales del marco (1 ). Como se puede observar en la figura 3, los puntos de ventilación (1 1 ) se encuentran conectadas a un conducto (12) de suministro de aire, comprendiendo la puerta isotérmica un dispositivo de ionización (6) del aire contenido en la cavidad intermedia (5). Como se puede observar en la figura 4 la ionización mediante el dispositivo ionizador (6) del aire contenido en la cavidad intermedia (5) provoca que la carga negativa del aire contenido entre las dos lonas provoque una atracción de los iones cargados positivamente y que se encuentran fuera de la cavidad intermedia (5) minimizando, de este modo, la recirculación del aire cercano a las lonas, incrementado consiguientemente el efecto aislante de la cavidad intermedia (5) de la puerta isotérmica. The canvases (31, 32) define each other an intermediate cavity (5) that is filled with air, preferably hot, projected through ventilation points (1 1) defined in the vertical uprights of the frame (1). As can be seen in Figure 3, the ventilation points (1 1) are connected to an air supply duct (12), the isothermal door comprising an ionization device (6) of the air contained in the intermediate cavity ( 5). As can be seen in Figure 4, the ionization by means of the ionizing device (6) of the air contained in the intermediate cavity (5) causes the negative charge of the air contained between the two canvases to cause an attraction of the positively charged ions and that they find outside the intermediate cavity (5) thus minimizing the recirculation of the air near the canvases, consequently increasing the insulating effect of the intermediate cavity (5) of the isothermal door.
Una vez descrita suficientemente la naturaleza de la invención, así como un ejemplo de realización preferente, se hace constar a los efectos oportunos que los materiales, forma, tamaño y disposición de los elementos descritos podrán ser modificados, siempre y cuando ello no suponga una alteración de las características esenciales de la invención que se reivindican a continuación. Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the essential features of the invention that are claimed below.
