DESCRIPCIÓN DESCRIPTION

Dispositivo de ventilación de un local en función de la humedad relativa medida. Ventilation device of a room depending on the relative humidity measured.

La presente invención se refiere a un dispositivo de ventilación apto para ventilar un local en función de la humedad relativa medida en el local con ayuda de un sensor sensible a la humedad. The present invention relates to a ventilation device capable of ventilating a room as a function of the relative humidity measured in the room with the aid of a moisture sensitive sensor.

Las diferentes estancias de un local presentan unas necesidades de ventilación variables en el tiempo unas con respecto a otras. Esta necesidad evoluciona principalmente en función del tipo de estancia y la ocupación. En lo que se refiere a las estancias técnicas, la necesidad de ventilación está en función esencialmente de las emisiones de vapores de agua. En lo que se refiere a las estancias principales, dormitorios y sala de estar, el número de personas que ocupan las estancias determina el nivel de ventilación necesario. The different rooms of a room have ventilation needs that vary over time with respect to each other. This need evolves mainly depending on the type of stay and occupation. As regards the technical rooms, the need for ventilation is essentially based on the emissions of water vapors. As regards the main rooms, bedrooms and living room, the number of people occupying the rooms determines the level of ventilation needed.

En la actualidad, la técnica más avanzada en materia de gestión de la necesidad de ventilación permite someter la superficie de paso de las entradas de aire a la humedad relativa de los locales ventilados, estando el nivel de humedad relativa ligado al nivel de humedad absoluta y a la temperatura por una ley de física que el experto en la materia determina y conoce perfectamente. Un dispositivo de ventilación de este tipo comprende una entrada de aire con superficie de paso modulable, mandada por un sensor. Este está constituido por un tejido sensible a la humedad que está alojado en el local a ventilar, y es sometido a transformaciones físicas de alargamiento o retracción en función de la humedad relativa que reina en el local. At present, the most advanced technique in the management of the need for ventilation allows subjecting the passage surface of the air inlets to the relative humidity of the ventilated premises, the relative humidity level being linked to the absolute humidity level and the temperature by a law of physics that the expert in the field determines and knows perfectly. A ventilation device of this type comprises an air inlet with a modular passage surface, commanded by a sensor. This is constituted by a moisture-sensitive tissue that is housed in the room to be ventilated, and is subjected to physical transformations of elongation or retraction depending on the relative humidity that reigns in the room.

El Documento US nº 4.460.122 divulga un dispositivo de ventilación según el preámbulo de la reivindicación 1. US 4,460,122 discloses a ventilation device according to the preamble of claim 1.

Para obtener un dispositivo de ventilación apto para medir unas variaciones de humedad relativa pequeñas debidas que resultan de la modificación de la ocupación del local, sea cual sea la estación, es sabido que el experto en la materia pone el sensor sensible a la humedad a una temperatura, por un lado, diferente de la del local a ventilar, y, por otro lado, teniendo en cuenta la temperatura exterior. La temperatura leída por el sensor sensible a la humedad se puede definir entonces mediante la siguiente ecuación: In order to obtain a ventilation device capable of measuring small relative humidity variations due to the modification of the occupation of the premises, whatever the season, it is known that the person skilled in the art puts the humidity sensitive sensor to a temperature, on the one hand, different from that of the premises to be ventilated, and, on the other hand, taking into account the outside temperature. The temperature read by the humidity sensitive sensor can then be defined by the following equation:

imagen1image 1

en la que Tcapt es la temperatura leída por el sensor, Tint la temperatura interior del local, Text la temperatura exterior y K el coeficiente de temperatura predefinido y comprendido generalmente entre 0,15 y 0,35 en las regiones templadas. in which Tcapt is the temperature read by the sensor, Tint the indoor temperature of the room, Text the outdoor temperature and K the pre-defined temperature coefficient and generally between 0.15 and 0.35 in the temperate regions.

En los dispositivos de ventilación actuales, el sensor sensible a la humedad está obligatoriamente colocado cerca de la entrada de aire para que esté en comunicación térmica con el aire exterior. Resultan de ello dos inconvenientes principales: In current ventilation devices, the humidity sensitive sensor is necessarily placed near the air inlet so that it is in thermal communication with the outside air. This results in two main drawbacks:

-por una parte, al poder variar el caudal de entrada de aire en una relación que va de 1 a 3 y a veces de 1 a 10, se deriva que los intercambios térmicos entre el aire exterior y el sensor sensible a la humedad no están verdaderamente controlados en todo momento. Por consiguiente, eso significa que no es posible fijar de forma duradera el coeficiente de temperatura K en el valor deseado y, -On the one hand, since the air inlet flow can be varied in a ratio ranging from 1 to 3 and sometimes from 1 to 10, it follows that the thermal exchanges between the outside air and the humidity sensitive sensor are not really controlled at all times. Therefore, that means that it is not possible to permanently set the temperature coefficient K at the desired value and,

-por otra parte, el montaje del dispositivo de ventilación es delicado de realizar y las configuraciones geométricas permitidas son limitadas porque es necesario integrar el sensor sensible a la humedad cerca de la entrada de aire. -On the other hand, the assembly of the ventilation device is delicate to perform and the geometric configurations allowed are limited because it is necessary to integrate the moisture sensitive sensor near the air inlet.

La presente invención tiene por objetivo resolver los inconvenientes citados anteriormente y se refiere con este fin a un dispositivo de ventilación según la reivindicación 1. The object of the present invention is to solve the aforementioned drawbacks and refers for this purpose to a ventilation device according to claim 1.

Así, el hecho de prever un conducto secundario independiente de la entrada principal permite controlar perfectamente la influencia de la temperatura exterior en el sensor sensible a la humedad. En efecto, al no estar ya este último en comunicación térmica con la entrada de aire principal, cuya superficie de paso es variable en función de la ocupación del local, sino con el conducto secundario cuya superficie de paso es independiente de la de la entrada de aire principal, se regulan los intercambios térmicos entre el aire exterior y el sensor sensible a la humedad y se puede obtener, por lo tanto, un coeficiente de temperatura K aún más estable sea cual sea el caudal de aire que pasa por la entrada principal. Thus, the fact of providing a secondary conduit independent of the main inlet allows to perfectly control the influence of the external temperature on the humidity sensitive sensor. In fact, since the latter is no longer in thermal communication with the main air inlet, whose passage surface is variable depending on the occupation of the premises, but with the secondary duct whose passage surface is independent of that of the entrance of main air, the thermal exchanges between the outside air and the humidity sensitive sensor are regulated and, therefore, an even more stable temperature coefficient K can be obtained regardless of the air flow through the main inlet.

Además, el montaje de un dispositivo de ventilación de este tipo se simplifica mucho ya que deja de ser necesario integrar el sensor sensible a la humedad cerca de la entrada de aire principal. El sensor sensible a la humedad puede entonces estar verdaderamente disociado y alejado de la entrada de aire principal. In addition, the assembly of such a ventilation device is greatly simplified since it is no longer necessary to integrate the moisture sensitive sensor near the main air inlet. The moisture sensitive sensor can then be truly dissociated and away from the main air inlet.

Según un primer modo de realización preferido de la invención, la sección de paso del conducto secundario es constante. Por consiguiente, la cantidad de aire que atraviesa la superficie de paso del conducto secundario es According to a first preferred embodiment of the invention, the passage section of the secondary conduit is constant. Therefore, the amount of air that passes through the passage surface of the secondary duct is
