Alternativamente, este filtro puede sustituirse por un simple laberinto de láminas perforadas para los casos en que no sea necesaria una filtración de partículas, ya sea por las características de la sala o por evitar el mantenimiento necesario. - una superficie activa aplicadora de fotocatálisis unida de manera indirecta sobre la base de soporte donde la superficie activa presenta un formato nido de abeja de alto caudal, capaz de inactivar sustancias realmente nocivas como los formaldehidos y VOC (elementos cancerígenos) que se encuentran en muchos plásticos y elementos constructivos. La superficie activa está revestida de nanopartículas de T¡02, que reacciona a la luz UV del interior del dispositivo, emitiendo radicales hidroxilo que reaccionan con las sustancias orgánicas para descomponerlas en no-tóxicas, así como microorganismos. La unidad de fotocatálisis aporta estos radicales al flujo de aire que circula por el equipo de tratamiento para alcanzar todo el volumen de la estancia. - a particle filter that is fixed on the support base, which in a possible embodiment has a level up to U15 through a HEPA filter, and which can also include pre-filters or intermediate filter elements. Alternatively, this filter can be replaced by a simple labyrinth of perforated sheets for cases where particle filtration is not necessary, either due to the characteristics of the room or to avoid the necessary maintenance. - an active photocatalysis applicator surface indirectly attached to the support base where the active surface presents a high flow honeycomb format, capable of inactivating really harmful substances such as formaldehydes and VOCs (carcinogenic elements) that are found in many plastics and construction elements. The active surface is coated with T¡0 2 nanoparticles, which react to UV light inside the device, emitting hydroxyl radicals that react with organic substances to decompose them into non-toxic, as well as microorganisms. The photocatalysis unit contributes these radicals to the air flow that circulates through the treatment equipment to reach the entire volume of the room.
- Unos medios de radiación ultravioleta en el rango preferente de los 254nm de longitud de onda, que comprende una cámara de radiación ultravioleta y unos tubos de emisión de dichas radiaciones alojados dentro de la cámara, quedando estos medios de radiación ultravioleta colocados por encima de la superficie activa aplicadora de fotocatálisis. Dicha cámara puede estar construida internamente con elementos reflectantes de la radiación, para mejorar el rendimiento. - A means of ultraviolet radiation in the preferential range of 254nm wavelength, which comprises an ultraviolet radiation chamber and tubes for the emission of said radiation housed inside the chamber, these ultraviolet radiation means being placed above the photocatalysis applicator active surface. Said chamber can be built internally with radiation reflective elements, to improve performance.
La generación de radiación UVC está debidamente controlada dentro del equipo, ya que puede dañar la retina y producir alteraciones en la piel si se expone directamente, a cualquier intensidad o potencia. Por la construcción del dispositivo, esta radiación al exterior está cancelada en presencia de personas. The generation of UVC radiation is properly controlled within the equipment, since it can damage the retina and produce alterations in the skin if it is exposed directly, at any intensity or power. Due to the construction of the device, this radiation to the outside is canceled in the presence of people.
El flujo de aire penetra en la cámara de radiación ultravioleta para inactivar aquellos organismos que eventualmente han sobrepasado las etapas anteriores, y que poseen ADN/ARN. Se utilizan lámparas de baja presión preferiblemente, dada sus características, y con filtro para evitar la generación de ozono en presencia de personas. Estas lámparas son relativamente potentes ya que la radiación UVC necesita un alto dosado para ser eficaz realmente. A diferencia de otros equipos domésticos, el dispositivo cuenta con más de 35mJ/cm2, por encima de la resistencia de la mayoría de los organismos nocivos. The air flow penetrates the ultraviolet radiation chamber to inactivate those organisms that have eventually passed the previous stages, and that possess DNA / RNA. Low pressure lamps are preferably used, given their characteristics, and with a filter to avoid the generation of ozone in the presence of people. These lamps are relatively powerful since UVC radiation requires a high dosage. to be really effective. Unlike other household equipment, the device has more than 35mJ / cm2, above the resistance of most harmful organisms.
Parte de la radiación empleada en la cámara de radiación UVC es utilizada para sensibilizar la etapa de fotocatálisis, reduciendo costes y haciendo el equipo más compacto y fácil de mantener. Part of the radiation used in the UVC radiation chamber is used to sensitize the photocatalysis stage, reducing costs and making the equipment more compact and easy to maintain.
La ubicación de la cámara de radiación es importante, ya que las partículas y organismos que escapan al filtrado HEPA (0.005%) son del tamaño ideal para ser inactivadas por la radiación UVC, por lo que ésta se comporta de forma más eficaz con tamaños pequeños, mientras que el HEPA se encarga de las más grandes. The location of the radiation chamber is important, since the particles and organisms that escape the HEPA filtering (0.005%) are the ideal size to be inactivated by UVC radiation, so it behaves more efficiently with small sizes while HEPA takes care of the larger ones.
La radiación UVC incide además de forma constante sobre los organismos atrapados en el filtro HEPA, por lo que terminan siendo inactivados dentro del mismo filtro, no siendo un simple freno y recolector de los mismos. Esto aumenta aún más la eficacia de la etapa de filtración HEPA. Esta topología es única y muy eficaz cuando el filtro está llegando a un nivel de saturación, que podría incluso ser perjudicial al almacenar durante el tiempo de vida organismos no deseados UVC radiation also constantly affects the organisms trapped in the HEPA filter, so they end up being inactivated within the filter itself, not being a simple brake and collector of them. This further increases the efficiency of the HEPA filtration stage. This topology is unique and very efficient when the filter is reaching a saturation level, which could even be detrimental when storing unwanted organisms during the lifetime

Para lograr una activación correcta el generador de ozono es conectable y se puede inhabilitar con un detector de presencia o una cámara que inhabilita el funcionamiento del subsistema. El sistema de generación de ozono también dispone de un sensor de medición de la concentración de este gas en el aire, que es comparado continuamente con el objetivo programado para modular el funcionamiento. Este sensor es utilizado además de manera complementaria para activar una señal óptico-acústica de no permanencia en caso de estar por encima del umbral de seguridad para las personas. To achieve correct activation, the ozone generator is connectable and can be disabled with a presence detector or a camera that disables the operation of the subsystem. The ozone generation system also has a sensor for measuring the concentration of this gas in the air, which is continuously compared with the programmed target to modulate the operation. This sensor is also used in a complementary way to activate an optical-acoustic signal of non-permanence in case of being above the safety threshold for people.
Además, este el sensor de ozono en caso de detectar una elevada concentración de ozono en el aire se pone en funcionamiento para hacer pasar al aire por unos filtros de carbón activado y reducir la concentración de ozono en el aire, evitando de esta manera la utilización de equipos secundarios para la eliminación del ozono de forma activa. In addition, this ozone sensor in case of detecting a high concentration of ozone in the air is put into operation to make the air pass through activated carbon filters and reduce the concentration of ozone in the air, thus avoiding the use of secondary equipment for the active elimination of ozone.
De manera complementaria y opcional el dispositivo purificador del aire puede contar con un segundo motor colocado en alguna de las ranuras obligando a la circulación del aire por las ranuras y a través de los filtros de carbón activado no haciendo necesario el accionamiento del motor interno asociado con el generador de ozono.

These activated carbon filters (16) are assembled in combination with gates (15) (Figures 1 and 2) which, by tilting, can leave the action of the activated carbon filters (16) active or inactive. The possible ways of operating the purification device are as follows: Either the device makes use of direct radiation leaving the rest of the elements inoperative, or a filtering process, UVC radiation, ozone generator and photocatalysis, or it acts in a way that eliminates the excess ozone contained in the room in case of having activated carbon filters.
El sistema completo puede incluir una diversidad de diferentes tipologías de dispositivos purificadores de aire, de características complementarias distribuidos por una sala y de tal forma que existe una simbiosis entre ellos, pudiendo existir: The complete system can include a variety of different types of air purifying devices, with complementary characteristics distributed throughout a room and in such a way that there is a symbiosis between them, and there may be:
■ un equipo principal (A) que dispone los elementos anteriormente descritos. ■ a main unit (A) that has the elements described above.
■ un equipo secundario (B) que dispone interiormente los mismos elementos excepto el filtro y el generador de ozono. El elemento filtrante ha sido sustituido por un filtro molecular capaz de eliminar el ozono de forma activa. ■ A secondary unit (B) that has the same elements internally except the filter and the ozone generator. The filter element has been replaced by a molecular filter capable of actively removing ozone.
En concreto este equipo secundario (B) surge de la necesidad posterior de eliminar el ozono producido durante la programación y antes de la entrada de personas en la sala. Specifically, this secondary equipment (B) arises from the subsequent need to eliminate the ozone produced during programming and before the entry of people into the room.
En el funcionamiento normal, que se muestra en la figura 5 corresponde cuando hay personas en la sala, los equipos A y B funcionan normalmente. El generador de ozono de A no está activado. In normal operation, shown in figure 5 corresponds to when there are people in the room, equipment A and B operate normally. A's ozone generator is not activated.
En funcionamiento con producción de ozono, tal y como se muestra en la figura 6, corresponde a una situación en que no hay personas en la sala, solamente los equipos A están activos y con el generador de ozono funcionando. Se evita que los equipos B intercepten el ozono con los filtros moleculares, por lo que permanecen detenidos. Una vez terminado el tratamiento de ozono, y antes de que las personas entren en la sala, situación que se muestra en la figura 7 los equipos A desactivan el generador de ozono y los equipos B se activan para eliminar el exceso de ozono a través de sus filtros moleculares. Cuando los niveles medidos son seguros para las personas, los sistemas avisan de forma óptica/acústica. In operation with ozone production, as shown in figure 6, it corresponds to a situation in which there are no people in the room, only equipment A is active and with the ozone generator running. The B teams are prevented from intercepting the ozone with the molecular filters, so they remain stopped. Once the ozone treatment is finished, and before people enter the room, a situation shown in figure 7, equipment A deactivates the ozone generator and equipment B is activated to eliminate excess ozone through its molecular filters. When the measured levels are safe for people, the systems warn optically / acoustically.
