Descripción del arte previo Description of prior art
Son por demás conocidos los dispositivos sopladores de aire, los cuales son colocados en los accesos que separan distintos ambientes y que tienen por finalidad mantener separadas dos masas de aire con características distintas de temperatura y/o humedad. A los fines de superar los inconvenientes que pueden generar las barreras físicas tales como puertas, portones o cortinas en cuanto a su frecuencia de apertura y cierre, estos dispositivos proveen una adecuada solución y simplicidad mecánica para mantener separados los ambientes y a su vez tener un adecuado ahorro energético. Air blowing devices are also known, which are placed in the entrances that separate different environments and whose purpose is to keep two air masses with different temperature and/or humidity characteristics separate. In order to overcome the inconveniences that can be generated by physical barriers such as doors, gates or curtains in terms of their opening and closing frequency, these devices provide an adequate solution and mechanical simplicity to keep the environments separate and at the same time have an adequate energy saving.
También existen dispositivos inyectores o sopladores de aire que lo inyectan dentro de los ambientes a los fines de regular las condiciones atmosféricas interiores tales como controlar temperatura, humedad, dispersión de aerosoles, contaminación y/o presión atmosférica. There are also injector devices or air blowers that inject it into environments for the purpose of regulating indoor atmospheric conditions such as controlling temperature, humidity, aerosol dispersion, contamination and/or atmospheric pressure.

Hoy en día y con la aparición de nuevas enfermedades tales como por ejemplo el COVID 19, existe la necesidad por motivos sanitarios y de higiene pública de mantener separadas a las personas a los fines de minimizar o eliminar el intercambio de materiales (líquidos, gaseosos o sólidos particulados) productos de la respiración, por ejemplo, exhalaciones, proyecciones de partículas de saliva, estornudos, etc. Today and with the appearance of new diseases such as COVID 19, there is a need for health and public hygiene reasons to keep people separated in order to minimize or eliminate the exchange of materials (liquids, gases or particulate solids) products of respiration, e.g. exhalations, projections of saliva particles, sneezes, etc.
Una de las formas de conseguir este objetivo es cumplir con la denominada distancia social, es decir, una distancia mínima de separación, en el orden de los 2 metros para el caso del COVID 19 según recomendación de la QMS, que deberán mantener los individuos entre ellos. Sin embargo, existen situaciones en las cuales el cumplir con esto puede generar una serie de inconvenientes funcionales o una subutilización de recursos. One of the ways to achieve this objective is to comply with the so-called social distance, that is, a minimum separation distance, in the order of 2 meters in the case of COVID 19 according to the QMS recommendation, which individuals must maintain between they. However, there are situations in which complying with this can generate a series of functional inconveniences or an underuse of resources.
Como ejemplo se puede mencionar el caso de ascensores, funiculares, cabinas tripuladas, buses o dispositivos los cuales han sido diseñados y optimizados de forma tal que las personas que los ocupan están muy próximas unas a otras y el hecho de mantener la denominada "distancia social" torna poco práctica su utilización. As an example we can mention the case of elevators, funiculars, manned cabins, buses or devices which have been designed and optimized in such a way that the people who occupy them are very close to each other and the fact of maintaining the so-called "social distance" makes their use impractical.
Ante esta necesidad, los dispositivos sopladores mencionados anteriormente del arte previo no pueden ser utilizados ya que no es esa su función de diseño. Faced with this need, the previously mentioned blowing devices of the prior art cannot be used since that is not their design function.
De acuerdo con la presente invención, se ha logrado que por medio de barreras de aire se generen cámaras o espacios individuales los cuales, que a pesar de la ausencia de barreras físicas, puedan garantizar el aislamiento de cada una de dichas cámaras o espacios individuales a los efectos de cumplir con la seguridad higiénica sanitaria mencionada anteriormente. Esta invención, el dispositivo de barrera de aire separadora de espacios, puede ser aplicada de forma tal de mantener aislada a una sola persona en forma selectiva, por ejemplo el chofer de un bus o colectivo, o bien a la totalidad del pasaje, por ejemplo, un ascensor. In accordance with the present invention, it has been achieved that by means of air barriers individual chambers or spaces are generated which, despite the absence of physical barriers, can guarantee the isolation of each of said individual chambers or spaces. the effects of complying with the sanitary hygienic safety mentioned above. This invention, the space-separating air barrier device, can be applied in such a way as to selectively keep a single person isolated, for example the driver of a bus or group, or the entire passenger, for example. , an elevator.
También puede ser aplicado en lugares en donde las personas estén haciendo una fila para esperar un turno o atención y no se pueda mantener la distancia o bien se quiera dar una protección adicional, como ejemplo se pueden citar lugares públicos en donde se hacen trámites, bancos, hospitales, etc. DESCRIPCIÓN DE LOS DIBUJOS It can also be applied in places where people are lining up to wait for a turn or service and cannot keep their distance or want to provide additional protection, such as public places where paperwork is done, banks , hospitals, etc DESCRIPTION OF THE DRAWINGS

DESCRIPCIÓN DE LA INVENCION DESCRIPTION OF THE INVENTION
La presente se refiere a un dispositivo de barrera de aire separador de espacios por medio de sopladores mecánicos que determinan una pluralidad de espacios de aislamiento individual con el fin de evitar la propagación de la contaminación aérea. Este dispositivo tiene la función de generar espacios o volúmenes los cuales se mantienen aislados unos de otros por medio del sostenimiento de un flujo vertical y continuo de una barrera de aire. The present refers to a space-separating air barrier device by means of mechanical blowers that determine a plurality of individual isolation spaces in order to prevent the spread of airborne contamination. This device has the function of generating spaces or volumes which are kept isolated from each other by maintaining a vertical and continuous flow of an air barrier.
Esta delimitación no es a los fines de preservar condiciones individuales de temperatura, humedad y/o presión en dichos espacios, sino que evita que exista el intercambio de materiales (gaseosos, líquidos o particulados sólidos) que emiten las personas a través de sus vías respiratorias, los cuales pueden ser vectores de enfermedades tal como bacterias, virus o cualquier otro tipo de material nocivo para la salud. This delimitation is not for the purpose of preserving individual conditions of temperature, humidity and/or pressure in said spaces, but it prevents the exchange of materials (gaseous, liquid or solid particles) that people emit through their respiratory tract. , which can be vectors of diseases such as bacteria, viruses or any other type of material harmful to health.
Este dispositivo es de aplicación a cualquier espacio cerrado o abierto en el cual las personas necesiten permanecer en reducida proximidad unas de otras por un lapso de tiempo. This device is applicable to any closed or open space in which people need to remain in close proximity to each other for a period of time.
Como ejemplo de aplicación podemos citar, ascensores, funiculares, trenes, buses, aviones, salas de espera o permanencia de personas, etc. Estos ejemplos no limitan de modo alguno la presente invención. As an example of application we can mention, elevators, funiculars, trains, buses, airplanes, waiting rooms or permanence of people, etc. These examples do not limit the present invention in any way.
Ejemplo de Realización Realization Example
A los fines explicativos, utilizaremos como ejemplo de realización, un ascensor. Este ejemplo no limita de modo alguno la presente invención. El dispositivo de la Figura 1 consta de una pluralidad de ventiladores centrífugos (1), pudiendo también ser radiales o de cualquier otro tipo que generen un caudal de aire adecuado para cumplir los requerimientos mínimos de velocidad que se citan más adelante, los cuales inyectan un caudal de aire a través de una pluralidad de boquillas (2), ver Figura 3, las cuales se ubican en el techo de la cabina del ascensor (3), ver Figura (1). For explanatory purposes, we will use an elevator as an example of embodiment. This example does not limit the present invention in any way. The device in Figure 1 consists of a plurality of centrifugal fans (1), which can also be radial or of any other type that generate an adequate air flow to meet the minimum speed requirements mentioned below, which inject a air flow through a plurality of nozzles (2), see Figure 3, which are located on the roof of the elevator car (3), see Figure (1).
La disposición de la pluralidad de boquillas (2) está hecha de tal manera que las mismas están ubicadas cenitalmente a la posición de la persona a la que se desea aislar, y son de forma alargada proyectando sobre los límites laterales del espacio individual que se genera. Esta distribución delimita una pluralidad de espacios rectangulares. Ver Figura 3. Para el caso de la figura 3, esta pluralidad de boquillas son cinco y determinan seis espacios individuales. The arrangement of the plurality of nozzles (2) is made in such a way that they are located zenithally to the position of the person whom it is desired to isolate, and they are elongated, projecting on the lateral limits of the individual space that is generated. . This distribution defines a plurality of rectangular spaces. See Figure 3. In the case of Figure 3, this plurality of nozzles is five and determines six individual spaces.
Otra disposición posible de las boquillas (2) es en forma curva o circular o poligonal , de modo de adaptarse a distintas posibles conformaciones de las cabinas o espacios. Another possible arrangement of the nozzles (2) is curved or circular or polygonal, so as to adapt to different possible configurations of the cabins or spaces.
El individuo a proteger percibe un flujo laminar de aire, el cual fluye a lo largo de su parte frontal, lateral y/o espalda de forma tal de interponerse entre él y la persona más próxima a su posición. La sección más alargada de la boquilla (2) es de forma rectangular, pudiendo sus vértices estar o no redondeados, y su sección más angosta puede tener sus caras paralelas o bien convergentes en dirección a la salida de aire, de modo de incrementar la velocidad de salida del fluido por efecto venturi. La sección más angosta de la boquilla tiene dimensiones que van de los 10 a 60 mm de ancho. Con este ancho de boquillas se logran velocidades de inyección elevadas con un caudal de aire 10 a 300 veces inferior al que se necesitaría si se quisiera imprimir esa velocidad al aire en toda la superficie de la cabina. Así se logra el efecto deseado con un mínimo de energía necesaria respecto a la otra posibilidad mencionada, esto es, imprimir esa velocidad al aire en toda la superficie de la cabina. The individual to be protected perceives a laminar flow of air, which flows along his front, side and/or back in such a way as to interpose himself between him and the person closest to his position. The longest section of the nozzle (2) is rectangular, and its vertices may or may not be rounded, and its narrowest section may have its faces parallel or converging in the direction of the air outlet, in order to increase the speed. outlet of the fluid by venturi effect. The narrowest section of the nozzle has dimensions ranging from 10 to 60 mm wide. With this width of nozzles, high injection speeds are achieved with an air flow 10 to 300 times lower than what would be needed if you wanted to print that speed to the air on the entire surface of the cabin. In this way, the desired effect is achieved with a minimum of necessary energy with respect to the other possibility mentioned, that is, printing that speed to the air on the entire surface of the booth.
La velocidad de aire necesaria para aislar a las personas entre sí de patógenos está relacionada con la velocidad del aire al salir por la nariz y por la boca ya sea respirando agitado o no agitado o estornudando o tosiendo que es de entre 0,2 a 1 m/s a la salida de la boca o nariz. Velocidades 3 a 7 veces superiores ya son suficientes para forzar hacia abajo el aliento apenas salido de boca o nariz evitando que se contamine al pasajero aun al más cercano. Además a medida que nos alejamos de la boca o nariz, la velocidad del aliento o aire expulsado va disminuyendo muy rápidamente por lo que el efecto es aún mayor en la zona perimetral. The speed of air necessary to isolate people from each other from pathogens is related to the speed of air exiting through the nose and mouth, whether breathing agitated or not, or sneezing or coughing, which is between 0.2 to 1 m/s at the exit of the mouth or nose. Speeds 3 to 7 times higher are already enough to force down the breath just out of the mouth or nose, preventing even the closest passenger from being contaminated. In addition, as we move away from the mouth or nose, the speed of the breath or expelled air decreases very quickly, so the effect is even greater in the perimeter area.
De acuerdo a los ensayos realizados, se determinó que la velocidad de salida del aire debe estar entre los 1 y 10 m/s, con valores de preferencia en el rango de los 7 m/s. Estas velocidades de salida de aire se han establecido para alturas de cabina de 2,3 m. En el caso en que la altura de cabina sea mayor, se deberá incrementar la velocidad de salida del fluido. According to the tests carried out, it was determined that the air outlet speed should be between 1 and 10 m/s, with preferred values in the range of 7 m/s. These air outlet speeds have been established for booth heights of 2.3m. In the event that the cabin height is greater, the fluid outlet speed must be increased.
En la Figura 6 se puede apreciar un corte horizontal a 1,6 m del piso de la cabina del ascensor de la Figura 1, en donde se ve la distribución de velocidades del aire. En dicha realización preferida, se ve una cabina de ascensor, separada en 6 zonas de aislamiento, las cuales están delimitadas por aire fluyendo en forma laminar, de arriba hacia abajo, a una velocidad mayor a 7 m/s (4), una pequeña zona adyacente de transición (5) en donde el aire disminuye su velocidad y la zona o volumen que ocupa la persona (6) con velocidades de aire inferior a 0,7 m/s a los fines de mantener una zona de confort. Figure 6 shows a horizontal section 1.6 m from the floor of the elevator cabin in Figure 1, where the distribution of air speeds can be seen. In said preferred embodiment, an elevator cabin is seen, separated into 6 isolation zones, which are delimited by air flowing in a laminar way, from top to bottom, at a speed greater than 7 m/s (4), a small adjacent transition zone (5) where the air slows down and the area or volume occupied by the person (6) with air speeds less than 0.7 m/s for the purpose of maintaining a comfort zone.
La cantidad de zonas de aislamiento puede aumentar o disminuir en función del tamaño de la cabina. The number of isolation zones can be increased or decreased depending on the size of the cabinet.
El dispositivo cuenta con un tablero de control con el cual se puede regular su encendido, apagado y velocidad de aire. El mismo puede estar ubicado dentro de la cabina, en el exterior o en cualquier lugar que se considere pertinente. The device has a control board with which you can regulate its on, off and air speed. It can be located inside the cabin, abroad or in any place that is considered appropriate.
También se pueden disponer sensores en cabina que identifiquen la cantidad y ubicación de los pasajeros para regular el flujo de aire y encender o apagar el sistema. Sensors can also be placed in the cabin that identify the number and location of passengers to regulate the flow of air and turn the system on or off.
Adicionalmente el dispositivo de barrera de aire separador de espacios individuales cuenta con rejillas (7) o conductos de salida del aire inyectado y también puede contar con conductos que dirijan el aire desde los ventiladores a las boquillas de inyección. Esto último dependerá de las características físicas del lugar en donde se instale el dispositivo de barrera de aire y la distancia que haya desde los sopladores a las boquillas. Additionally, the individual space separating air barrier device has grids (7) or outlet ducts for the injected air and can also have ducts that direct the air from the fans to the injection nozzles. The latter will depend on the physical characteristics of the location where the air barrier device is installed and the distance from the blowers to the nozzles.
Las rejillas (7) tienen por finalidad garantizar la circulación del aire, permitiendo su salida, en las condiciones de velocidad establecidas anteriormente. The purpose of the grids (7) is to guarantee the circulation of air, allowing its exit, under the previously established speed conditions.
El dispositivo de barrera de aire separador de espacios individuales puede ser provisto de elementos filtrantes ya sea en la admisión de los ventiladores o bien en una ubicación entre los ventiladores y las boquillas. The individual space separating air barrier device may be provided with filter elements either at the intake of the fans or at a location between the fans and the nozzles.
También se pueden proveer dispositivos que inyecten junto con el aire sustancias sanitizantes a los fines higiénicos/desinfectantes o aromáticas a los fines del confort, o bien que inyecten aire filtrado, sanitizado o natural en forma complementaria dentro de la zona del espacio individual delimitado por la barrera de aire, a los fines de proveer ventilación al individuo que ocupa el espacio. Es de destacar que la inyección de este aire es a baja velocidad y no se mezcla con el inyectado a alta velocidad por la barrera de aire. Devices can also be provided that inject sanitizing substances together with the air for hygienic/disinfectant or aromatic purposes for comfort purposes, or that inject filtered, sanitized or natural air in a complementary way within the area of the individual space delimited by the air barrier, in order to provide ventilation to the individual who occupies the space. It is noteworthy that the injection of this air is at low speed and does not mix with that injected at high speed by the air barrier.
En el caso de habitáculos que tienen instalados dispositivos sanitizantes por UV, cuando no hay pasajeros, el forzamiento de la circulación del aire, elimina la potencial presencia de ozono en la cabina. In the case of cabins that have UV sanitizing devices installed, when there are no passengers, forcing air circulation eliminates the potential presence of ozone in the cabin.
También al ser el aire que se inyecta el provisto desde el pasadizo, en el caso de un ascensor, este no se contamina ya que el volumen del pasadizo por donde circula el ascensor es 10 a 150 veces el de la cabina y con tiraje a los cuatro vientos en la parte superior del edificio, teniendo la ventaja de evitar el uso de filtros y por consiguiente mayores potencias en los motores de sopladores para vencer la caída de presión producida por los filtros.Also, since the air that is injected is supplied from the passageway, in the case of an elevator, it is not contaminated since the volume of the passageway through which the elevator circulates is 10 to 150 times that of the cabin and with drafts at four winds in the upper part of the building, having the advantage of avoiding the use of filters and therefore greater power in the blower motors to overcome the pressure drop produced by the filters.
Sin embargo, el uso de filtros no se descarta en el presente desarrollo. However, the use of filters is not ruled out in the present development.
Al momento de abrirse las puertas del ascensor, la presión en el interior es positiva, impidiendo el acceso de aire de los palieres o salas, circunstancia especialmente importante en salas de emergencia o terapia intensiva en hospitales. When the elevator doors open, the pressure inside is positive, preventing the access of air from the halls or rooms, a circumstance that is especially important in emergency rooms or intensive care in hospitals.
