Description

APARATO DE AIRE ACONDICIONADO CON CONTROL DE OXIGENO  AIR CONDITIONING DEVICE WITH OXYGEN CONTROL
CAMPO TÉCNICO DE LA INVENCIÓN. TECHNICAL FIELD OF THE INVENTION.
La presente invención puede ser aplicada principalmente en la industria médica, industria de aparatos electrodomésticos y otros sectores donde es conveniente generar una atmósfera rica en oxigeno para beneficio de las personas que en ella se encuentren. The present invention can be applied mainly in the medical industry, home appliance industry and other sectors where it is convenient to generate an oxygen-rich atmosphere for the benefit of the people in it.
ANTECEDENTES DE LA INVENCIÓN. BACKGROUND OF THE INVENTION
De acuerdo con la NASA una persona promedio necesita 0.84 kg de 02 por día (y noche), con lo que se caku\a un volumen de 588 litros de consumo al día, más de medio metro cúbico, lo equivalente contenido en 2.94 m3 de aire, pues la concentración de oxígeno 02 en la atmósfera es 21%. According to NASA, an average person needs 0.84 kg of 0 2 per day (and night), which means that a volume of 588 liters per day is consumed, more than half a cubic meter, the equivalent contained in 2.94 m 3 of air, since the oxygen concentration 0 2 in the atmosphere is 21%.
Con la información anterior se estima que 4 personas presentes en una habitación de 5m x 5m x 3m sellada se terminarían el oxígeno en menos de 8 días. Sin embargo hay estándares como el de la Occupational Safety and Health Administration en EEUU que indican que una concentración menor de 19.5% significa una deficiencia de oxígeno, donde las personas disminuyen su rendimiento en tareas enérgicas y pudieran presentar síntomas como sensación de sofoco y leves mareos. Se estima entonces que transcurrido un día en la habitación sellada ya se encontraría el nivel de oxígeno a una concentración menor que la recomendada. With the above information, it is estimated that 4 people present in a sealed 5m x 5m x 3m room would complete the oxygen in less than 8 days. However, there are standards such as that of the Occupational Safety and Health Administration in the US that indicate that a concentration below 19.5% means an oxygen deficiency, where people decrease their performance in energetic tasks and may present symptoms such as hot flashes and mild dizziness. . It is then estimated that after one day in the sealed room, the oxygen level would already be found at a lower concentration than recommended.
Existen individuos con distintos padecimientos como enfisema, sarcoidosis u obstrucción pulmonar crónica que requieren de una concentración mayor de 02 para lograr la captación correcta de este gas. There are individuals with different conditions such as emphysema, sarcoidosis or chronic pulmonary obstruction that require a concentration greater than 0 2 to achieve the correct uptake of this gas.
En la actualidad existen distintas soluciones ante la creciente necesidad de las personas (con o sin afecciones pulmonares), principalmente en ciudades grandes, de disponer de sesiones con oxigenoterapia come los bares de oxígeno, las cámaras hiperbáricas y concentradores de oxígeno domésticos, donde en la mayoría de los casos son expuestos a cortos periodos a una alta concentración de oxígeno (alrededor de 90%). Una solución propuesta a la problemática es la implementación de un sistema de concentración de oxígeno a un sistema de refrigeración mini-split. Con el complemento el aparato podrá lograr niveles óptimos de oxígeno de acuerdo a la necesidad de la(s) persona(s) que se encuentren en alguna habitación. Currently there are different solutions to the growing need of people (with or without lung conditions), mainly in large cities, to have sessions with oxygen therapy eat oxygen bars, hyperbaric chambers and domestic oxygen concentrators, where in the Most cases are exposed to short periods of high oxygen concentration (about 90%). A proposed solution to the problem is the implementation of an oxygen concentration system to a mini-split cooling system. With the complement the device can achieve optimal levels of oxygen according to the need of the person (s) in a room.
Este aparato tendrá la capacidad de mantener la concentración común de oxígeno en el aire (21%) o incluso aumentarla si se tiene una prescripción médica; en caso de hacerse se deberían tomar medidas y adecuar la habitación con determinadas indicaciones contra incendios, pues los estándares manejan también que a partir de 23.5% de oxígeno ya se considera de riesgo para la aceleración de la combustión. This device will have the ability to maintain the common concentration of oxygen in the air (21%) or even increase it if you have a medical prescription; in case of being done, measures should be taken and the room adapted with certain indications against fires, since the standards also manage that from 23.5% of oxygen it is already considered a risk for the acceleration of combustion.
Existen distintas técnicas para lograr la concentración de oxígeno en el aire como por criogenia, membrana y otras, pero la que más se adecúa a la necesidad de consumo doméstico y por lo tanto la que se utilizará en la invención es adsorción por cambios de presión (PSA por sus siglas en inglés). There are different techniques to achieve the concentration of oxygen in the air such as cryogenics, membrane and others, but the one that best suits the need for domestic consumption and therefore that which will be used in the invention is adsorption by pressure changes ( PSA by its acronym in English).
El sistema concentrador de oxígeno aprovecha el calor liberado en el serpentín condensador del sistema de refrigeración para ayudar en la regeneración del tamiz molecular utilizado en la invención mediante un intercambiador de calor en la forma de serpentín mencionada. The oxygen concentrator system takes advantage of the heat released in the condensing coil of the refrigeration system to aid in the regeneration of the molecular sieve used in the invention by means of a heat exchanger in the mentioned coil form.

En relación a las figuras anteriormente mencionadas, el presente ejemplo describe una de las modalidades preferentes para la realización del dispositivo concentrador de oxígeno, utilizado en la invención. El sistema incluye un compresor (1) conectado con, al menos, una columna de adsorción (4) a través de una columna de secado (2) y una electroválvula de tres vías (3). In relation to the aforementioned figures, the present example describes one of the preferred embodiments for the realization of the oxygen concentrating device, used in the invention. The system includes a compressor (1) connected with at least one adsorption column (4) through a drying column (2) and a three-way solenoid valve (3).
La columna de secado (2) utiliza gel de sílice para atrapar las moléculas de agua presentes en el aire inyectado por el compresor. The drying column (2) uses silica gel to trap the water molecules present in the air injected by the compressor.
La electroválvula de tres vías (3) permitirá, al comienzo del proceso, el flujo de gas hacia la columna de adsorción y hacia fuera del sistema para que escape el N2 filtrado y dar cabida de comenzar de nuevo el proceso. La columna de adsorción (4) contiene zeolita 5A en forma de pequeñas esferas con el propósito de atrapar el oxígeno del aire y permitir solamente el paso de gas con oxígeno en su mayoría. Está conectada con el tanque de almacenamiento de 02 (6) mediante una electroválvula de dos vías (5) que permite el flujo de aire sólo hacia el tanque de almacenamiento (6). The three-way solenoid valve (3) will allow, at the beginning of the process, the flow of gas towards the adsorption column and out of the system so that the filtered N 2 escapes and allows the process to begin again. The adsorption column (4) contains zeolite 5A in the form of small spheres for the purpose of trapping oxygen from the air and allowing only the passage of gas with mostly oxygen. It is connected to the 0 2 storage tank (6) by a two-way solenoid valve (5) that allows the flow of air only to the storage tank (6).
En la salida del aparato se encuentra una electroválvula de dos vías (7) que permite el flujo de salida del gas enriquecido con 02. At the outlet of the device is a two-way solenoid valve (7) that allows the outflow of the enriched gas with 0 2 .
El controlador (8) monitoriza la presión en la columna de adsorción (4) y en el tanque de almacenamiento (6) a través de los sensores de presión (SI y S2) para controlar el ciclo a través del accionamiento del compresor y electroválvulas (1, 3, 5, 7). The controller (8) monitors the pressure in the adsorption column (4) and in the storage tank (6) through the pressure sensors (SI and S2) to control the cycle through the operation of the compressor and solenoid valves ( 1, 3, 5, 7).
Se encuentra también un conducto (9) que hace contacto con la columna de adsorción (4) en forma helicoidal alrededor de dicha columna, aunque puede ser de otra forma, que transporta líquido caliente desde un serpentín intercambiador de calor (11). Este serpentín (11) absorbe el calor liberado por el sistema de refrigeración estando en contacto con el serpentín condensador (14). Esto se logra generando un flujo de líquido en sentido contrario al del gas refrigerante durante su paso por el serpentín condensador (14). There is also a conduit (9) that makes contact with the adsorption column (4) in a helical manner around said column, although it may be otherwise, which carries hot liquid from a heat exchanger coil (11). This coil (11) absorbs the heat released by the cooling system while in contact with the condenser coil (14). This is achieved by generating a liquid flow in the opposite direction to the refrigerant gas during its passage through the condenser coil (14).
La corriente del líquido que calentará la columna de adsorción (4) a través del conducto helicoidal (9) será generada por un bombeador (8) y será controlada también mediante la activación de una electroválvula (10) para asegurar el corte de flujo de líquido cuando no es necesario. The flow of the liquid that will heat the adsorption column (4) through the helical duct (9) will be generated by a pump (8) and will also be controlled by activating an electrovalve (10) to ensure the cut of liquid flow when it's not necessary

En relación a las figuras presentes en este documento, el presente ejemplo describe una de las modalidades preferentes para el funcionamiento del dispositivo concentrador de oxígeno, utilizado en invención.  oxygen in the apparatus included in the invention. In relation to the figures present in this document, the present example describes one of the preferred embodiments for the operation of the oxygen concentrating device, used in the invention.
Al inicio del proceso el controlador activa el compresor (1) junto con la electroválvula (3) para comenzar a depositar aire, a través de la columna de secado (2), dentro de la columna de adsorción (4). Cuando el sensor (SI) detecta el nivel alto adecuado de presión se activa la electroválvula (5) para permitir el paso del gas enriquecido en oxígeno hacia el tanque de almacenamiento. At the beginning of the process the controller activates the compressor (1) together with the solenoid valve (3) to begin to deposit air, through the drying column (2), inside the adsorption column (4). When the sensor (SI) detects the appropriate high level of pressure, the solenoid valve (5) is activated to allow the passage of oxygen-enriched gas into the storage tank.
Cuando el sensor (SI) detecta ahora el nivel bajo adecuado de presión se desactiva la electroválvula (5) y se cambia de posición la e\ectrová\vu\a (3) para permitir el escape del nitrógeno contenido en la columna (4). When the sensor (SI) now detects the appropriate low pressure level, the solenoid valve (5) is deactivated and the e \ ectrová \ vu \ a (3) is repositioned to allow the escape of the nitrogen contained in the column (4) .
Paralelamente a este último paso mencionado se activa la bomba (8) y la electroválvula (10) para comenzar a circular agua caliente desde el ¡ntercambiador de calor (11) hacia el conducto helicoidal (9) que hace contacto con la columna de adsorción (4), con el fin de mejorar la regeneración de la zeolita contenida dentro de dicha columna (4). Parallel to this last mentioned step, the pump (8) and the solenoid valve (10) are activated to start circulating hot water from the heat exchanger (11) to the helical duct (9) that makes contact with the adsorption column ( 4), in order to improve the regeneration of the zeolite contained within said column (4).
Pasado un tiempo determinado y cuando la presión dentro de la columna de lavado (4) se iguala a la presión atmosférica se desactiva la bomba de agua caliente (8) y la electroválvula (10), además de cambiar la posición la electroválvula de tres vías (3) para que permita el flujo de nuevo sólo hacia la columna de adsorción (4) y comenzar de nuevo el proceso a través de la activación After a certain time and when the pressure inside the wash column (4) is equal to the atmospheric pressure, the hot water pump (8) and the solenoid valve (10) are deactivated, in addition to changing the position of the three-way solenoid valve (3) to allow the flow back only towards the adsorption column (4) and start the process again through activation
Como se describe, el proceso es semi continuo en el cual se va almacenando el producto enriquecido de oxígeno eri el tanque de almacenamiento (6) para administrar al ambiente cuando sea necesario, a través de la activación de la electroválvula (7). As described, the process is semi-continuous in which the oxygen-enriched product is stored in the storage tank (6) to be administered to the environment when necessary, through the activation of the solenoid valve (7).
Ejemplo 3. Diseño preferente para la realización del sistema de refrigeración Example 3. Preferred design for the realization of the cooling system
utilizado como componente de la presente invención.  used as a component of the present invention.
En relación a la figura 2, el presente ejemplo describe una de las modalidades preferentes para la realización del dispositivo de refrigeración, utilizado en la invención . El sistema incluye un compresor (13) que comprime un gas refrigerante, comúnmente el R407C. In relation to Figure 2, the present example describes one of the preferred embodiments for the realization of the refrigeration device, used in the invention. The system includes a compressor (13) that compresses a refrigerant gas, commonly the R407C.
El compresor (13) está conectado a un serpentín condensador (14) con disipador de calor (15) donde el refrigerante pierde calor y, al estar sometido a una alta presión, pasa a su estado líquido. El conducto continúa en su trayecto hacia la habitación a enfriar donde se encuentra una válvula de expansión (16). Seguidamente dentro de la habitación el líquido pasa a un serpentín evaporador (17). Está presente un abanico que recircula el aire (18) a través de dicho serpentín para que las moléculas del refrigerante cedan calor al viento de la habitación y sea expandido hasta volver a su estado gaseoso. The compressor (13) is connected to a condenser coil (14) with heat sink (15) where the refrigerant loses heat and, when subjected to high pressure, enters its liquid state. The duct continues on its way to the room to cool where an expansion valve (16) is located. Then inside the room the liquid passes to an evaporating coil (17). There is a fan that recirculates the air (18) through said coil so that the molecules of the refrigerant give heat to the wind in the room and is expanded until it returns to its gaseous state.
Al salir el refrigerante del serpentín evaporador (17) en forma de gas vuelve al compresor (13) para dar inicio de nuevo al proceso. When the refrigerant leaves the evaporator coil (17) in the form of gas, it returns to the compressor (13) to start the process again.
Está presente un sensor de temperatura (S3) que envía señales al controlador para monitorizar el nivel de enfriamiento y determinar la capacidad de funcionamiento del compresor (13). A temperature sensor (S3) is present that sends signals to the controller to monitor the cooling level and determine the compressor's operating capacity (13).
Ejemplo 4. Funcionamiento y procedimiento para el aparato de refrigeración Example 4. Operation and procedure for the refrigeration apparatus
incluido en la invención. El sistema de refrigeración comienza cuando el controlador activa el compresor (13), éste comprime el gas refrigerante para hacerlo pasar por el serpentín condensador (14) y, ayudado del disipador de calor (15), el gas se enfría hasta llegar a su estado líquido.  included in the invention. The cooling system begins when the controller activates the compressor (13), it compresses the refrigerant gas to pass it through the condenser coil (14) and, aided by the heat sink (15), the gas cools until it reaches its state liquid.
Este líquido continúa por el conducto en su camino hacia la habitación a enfriar al pasar por la válvula de expansión (16). El efecto logrado es disminuir la presión del siguiente paso donde continúa por un.serpentín evaporador (17). This liquid continues through the conduit on its way to the room to cool as it passes through the expansion valve (16). The effect achieved is to reduce the pressure of the next step where it continues through an evaporator coil (17).
El abanico (18) hace circular el aire de la habitación a través de dicho serpentín (17) para que el refrigerante gane calor del aire de la habitación y termine de pasar a su estado gaseoso. El refrigerante, ahora en estado gaseoso, continúa su trayecto para ser aspirado de nuevo por el compresor (13) y ser comprimido en el nuevo ciclo.  The fan (18) circulates the air in the room through said coil (17) so that the refrigerant gains heat from the air in the room and ends up in its gaseous state. The refrigerant, now in a gaseous state, continues its path to be sucked back by the compressor (13) and compressed in the new cycle.
De acuerdo a la señal enviada por el sensor de temperatura (S3) el controlador determinará la potencia de funcionamiento del compresor (13) para lograr el nivel de enfriamiento requerido. Ejemplo 5. Funcionamiento y procedimiento para el intercambiador de calor According to the signal sent by the temperature sensor (S3) the controller will determine the operating power of the compressor (13) to achieve the required cooling level. Example 5. Operation and procedure for the heat exchanger
entre el sistema de refrigeración y el sistema de concentración de oxígeno  between the cooling system and the oxygen concentration system
Respecto al intercambiador de calor mostrado en la figura 3, se muestra cómo se acoplan y hacen contacto los serpentines intercambiadores de calor (11 y 14). With respect to the heat exchanger shown in Figure 3, it is shown how the heat exchanger coils (11 and 14) are coupled and made contact.
La función del conducto (14) es ceder calor al agua recirculado por el conducto (11) mediante la técnica de crear flujos cruzados. Esto ayuda a que el gas refrigerante comprimido pase a su estado líquido más rápidamente. The function of the duct (14) is to give heat to the water recirculated by the duct (11) by the technique of creating cross flows. This helps the compressed refrigerant gas to enter its liquid state more quickly.
A su vez, el agua calentada es bombeada, mediante la activación del dispositivo (8) y la electroválvula (10), hacia el conducto helicoidal (9) que hace contacto con la columna de adsorción (4). Al calentar la. zeolita contenida en dicha columna (4) ayuda a lograr una regeneración completa de la zeolita durante la etapa de escape de nitrógeno. In turn, the heated water is pumped, by activating the device (8) and the solenoid valve (10), into the helical duct (9) that makes contact with the adsorption column (4). When heating the. Zeolite contained in said column (4) helps to achieve a complete regeneration of the zeolite during the nitrogen escape stage.
Al terminar esta etapa se cierra la electroválvula (10) y desactiva la bomba (8) para que la columna de adsorción (4) deje de ganar calor para dar pie al nuevo ciclo de concentración de oxígeno. At the end of this stage, the solenoid valve (10) is closed and the pump (8) is deactivated so that the adsorption column (4) stops gaining heat to give rise to the new oxygen concentration cycle.
