Description
SISTEMA DE ENFRIAMIENTO ADIABÁTICO EN POSICIÓN V ADIABAT COOLING SYSTEM IN POSITION V
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
Por medio de la presente invención, se pretende dar amplia protección al sistema de enfriamiento adiabático de aire ambiente ACS (Adiabatic Cooling System), el cual tiene una configuración en posición de tipo V, la disposición de sus elementos le permite ser instalado paralelamente a cada uno de los serpentines en forma de V, de tal manera que los paneles de enfriamiento adiabático se encuentran paralelos al área o cara aletada en dirección del flujo del aire del intercambiador de calor, aprovechando así el 100% de la superficie de intercambio sin restricción en toda el área aletada. By means of the present invention, it is intended to give ample protection to the ACS (Adiabatic Cooling System) ambient air adiabatic cooling system, which has a V-type configuration, the arrangement of its elements allows it to be installed parallel to each one of the V-shaped coils, such that the adiabatic cooling panels are parallel to the finned area or face in the direction of the air flow of the heat exchanger, thus taking advantage of 100% of the unrestricted exchange surface in All finned area.
El sistema de enfriamiento adiabático en posición V, cuenta con charolas recolectoras de agua en el inferior del panel de enfriamiento, e interconectadas por medio de la tubería de drenado, lo que permite tener solo una conexión de dren en el condensador o enfriador, excepto cuando el flujo de agua es mayor se tienen 2 conexiones de dren uno por cada charola recolectora. The adiabatic cooling system in position V, has water collector trays in the bottom of the cooling panel, and interconnected by means of the drain pipe, allowing only a drain connection in the condenser or cooler, except when the water flow is greater there are 2 drain connections one for each collection tray.
Asimismo y dada la posición paralela previamente descrita, la superficie de instalación necesaria para múltiples sistemas se ve reducida hasta en un 50%, sin que el rendimiento del sistema de enfriamiento se vea alterado. Also and given the parallel position previously described, the installation surface required for multiple systems is reduced by up to 50%, without the performance of the cooling system being altered.
ANTECEDENTES BACKGROUND
Existen en el mercado enfriadores de líquido y condensadores enfriados por aire atmosférico en el que se provee agua en forma atomizada para enfriar de manera adiabática la corriente de aire entrante. Estos sistemas se pueden distinguir de los
sistemas del tipo aspersión, que rocían el agua en el espacio o ambiente que rodea el enfriador de fluido o el condensador y con los sistemas del tipo atomizado en donde el agua es rociada directamente a la propia superficie del intercambiador de calor, la cual se evapora al entrar en contacto con la corriente de aire. La patente Europea EP 1698847 Al muestra un sistema adiabático híbrido en el cual dos secciones de intercambio de calor son presentadas; la primera siendo un intercambiador de calor de convección forzada por donde circula un fluido procesado y el segundo, el cual puede operar en modo húmedo o seco. There are liquid coolers and condensers cooled by atmospheric air on the market in which water is provided in an atomized form to cool the incoming air stream adiabically. These systems can be distinguished from sprinkler type systems, which spray water into the space or environment surrounding the fluid cooler or condenser and with atomized type systems where water is sprayed directly to the heat exchanger surface itself, which evaporates when coming into contact with the air flow. European Patent EP 1698847 Al shows a hybrid adiabatic system in which two heat exchange sections are presented; the first being a forced convection heat exchanger through which a processed fluid circulates and the second, which can operate in wet or dry mode.
Para mayores temperaturas se usa el modo húmedo, en donde un líquido evaporable se distribuye en un panel de enfriamiento conocido como "cooling pad" siendo esta una sección de intercambio directo de calor en donde la corriente de aire entrante es primeramente saturada adiabáticamente con un líquido evaporable para pre-enfriar el aire por debajo de su temperatura de bulbo seco antes de entrar al intercambiador de aletas o sistema seco de convección forzada. Por otro lado la patente US 2010199714, se refiere a un sistema de enfriamiento por aire tipo "V" que tienen una sección de condensador dimensionado para que coincida con la capacidad enfriadora y un medio de refrigeración auxiliar mediante el uso de una bobina de refrigeración independiente que se encuentra dentro del condensador de corriente, pero utiliza el espacio disponible dentro del condensador existente, así como una pequeña porción del flujo de aire impulsado por el ventilador del condensador. For higher temperatures, the wet mode is used, where an evaporable liquid is distributed in a cooling panel known as the "cooling pad", this being a direct heat exchange section where the incoming air stream is first adiabatically saturated with a liquid evaporable to pre-cool the air below its dry bulb temperature before entering the fin exchanger or dry forced convection system. On the other hand, US patent 2010199714, refers to a "V" type air cooling system having a condenser section sized to match the cooling capacity and an auxiliary cooling medium by using an independent cooling coil which is located within the current condenser, but uses the available space within the existing condenser, as well as a small portion of the air flow driven by the condenser fan.
Sin embargo, ninguno de los documentos citados anteriormente comprende paneles de enfriamiento en forma de "V, quedando dichos paneles paralelos o casi paralelos
a los serpentines de forma que el aire llega a los serpentines inmediatamente después de pasar por los paneles húmedos, asimismo el sistema de la presente invención solo tiene una estructura metálica en la que se apoya careciendo de paredes verticales, esto con el fin de eliminar los espacios entre dos sistemas de enfriamiento y favorecer la circulación del aire libremente por toda el área de los paneles húmedos. However, none of the documents cited above comprise "V-shaped" cooling panels, said panels being parallel or almost parallel. to the coils so that the air reaches the coils immediately after passing through the wet panels, also the system of the present invention only has a metal structure on which it rests lacking vertical walls, this in order to eliminate the spaces between two cooling systems and favor air circulation freely throughout the area of the wet panels.
Los sistemas que funcionan rociando agua tanto al ambiente que rodea el enfriador de fluido seco o condensador asi como los que rocían directamente la superficie del intercambiador de calor tienen la desventaja que con la saturación y humedad presente en el espacio interno provoca corrosión y calcificación de los elementos del equipo, provocando así elevados costos de mantenimiento. Systems that work by spraying water to both the environment surrounding the dry fluid cooler or condenser as well as those that directly spray the surface of the heat exchanger have the disadvantage that with the saturation and humidity present in the internal space causes corrosion and calcification of the equipment elements, thus causing high maintenance costs.
Es posible considerar un sistema de desmineralización del agua para prevenir los efectos físicos previamente descritos, sin embargo el costo de estos sistemas es elevado por lo que no se justifica. It is possible to consider a water demineralization system to prevent the physical effects previously described, however the cost of these systems is high, so it is not justified.
El sistema adiabático híbrido aunque provee ventajas al presentar modalidades de convección forzada y de panel de enfriamiento (pad) en seco y húmedo, este no ofrece en su configuración una distancia óptima entre el panel de enfriamiento y el serpentín intercambiador de calor, ya que al no estar diseñado de forma paralela y en tipo "V", entre el pad y el intercambiador existen diferencias de temperatura del fluido a enfriar (menos distancia entre pad y serpentín en la parte superior, y mayor distancia en la parte inferior) Although the hybrid adiabatic system provides advantages by presenting modalities of forced convection and dry and wet cooling panel (pad), it does not offer in its configuration an optimal distance between the cooling panel and the heat exchanger coil, since at not being designed in parallel and in type "V", between the pad and the exchanger there are temperature differences of the fluid to be cooled (less distance between pad and coil at the top, and greater distance at the bottom)
Es decir, se presentan oscilaciones de mayor y menor temperatura, lo cual disminuye la eficiencia del sistema, de la misma manera al ser el pad una estructura vertical este tiene la desventaja de aumentar el área de piso de la instalación para múltiples
sistemas, esto es, que se requiere una mayor distancia entre unidades (en este caso la distancia mínima necesaria es igual a la altura de las unidades). That is, there are oscillations of higher and lower temperature, which decreases the efficiency of the system, in the same way as the pad is a vertical structure this has the disadvantage of increasing the floor area of the installation for multiple systems, that is, a greater distance between units is required (in this case the minimum necessary distance is equal to the height of the units).

DESCRIPCIÓN DETALLADA DELA INVENCIÓN DETAILED DESCRIPTION OF THE INVENTION
El sistema de enfriamiento adiabático de aire ambiente en posición "V" de la presente invención es un dispositivo que por medio de un proceso psicométrico, reduce la temperatura de bulbo seco (BS) del aire atmosférico hasta unos 2 a 4 grados Centígrados por arriba de la temperatura de bulbo húmedo (BH) del lugar. The adiabatic cooling system of ambient air in the "V" position of the present invention is a device that by means of a psychometric process reduces the dry bulb temperature (BS) of atmospheric air to about 2 to 4 degrees Celsius above the wet bulb temperature (BH) of the place.
Éste aire a temperatura muy cercana a la de bulbo húmedo, entra al intercambiador de calor de tubo aletado, como medio condensante o como medio de enfriamiento del fluido que circula dentro del intercambiador de calor de tubo aletado. This air at a temperature very close to that of a wet bulb enters the finned tube heat exchanger, as a condensing medium or as a means of cooling the fluid circulating inside the finned tube heat exchanger.
Al entrar el aire al intercambiador a una temperatura más baja que la temperatura de BS, la capacidad del intercambiador se incrementa significativamente con respecto a su capacidad si se considera el aire entrando a temperatura de BS, con lo cual se disminuye el consumo de energía de los ventiladores. Los paneles de enfriamiento, permiten mantener la superficie aletada del serpentín seca, ya que la superficie aletada del serpentín no tiene contacto ni con el panel ni con el agua que corre por el panel de enfriamiento por lo que la acumulación de sedimentos minerales es mínimo, además los paneles no están en contacto con los serpentines, ya que entre el panel de enfriamiento y el serpentín hay una distancia aproximada 100mm (arriba la distancia puede ser entre 50mm hasta 100mm y en la parte baja de 100 a 150mm). When the air enters the exchanger at a temperature lower than the BS temperature, the capacity of the exchanger is significantly increased with respect to its capacity if the air is considered entering BS temperature, which decreases the energy consumption of the fans. The cooling panels allow the finned surface of the coil to be kept dry, since the finned surface of the coil has no contact with either the panel or the water that runs through the cooling panel so that mineral sediment accumulation is minimal, In addition the panels are not in contact with the coils, since between the cooling panel and the coil there is an approximate distance of 100mm (above the distance can be between 50mm to 100mm and at the bottom of 100 to 150mm).
El Sistema de Enfriamiento Adiabático tipo "V", está configurado de tal forma que el panel de enfriamiento o "pad" está en posición "V" y acompaña de forma paralela a los serpentines también dispuestos en "V", de tal manera que los paneles de enfriamiento se encuentran en una disposición paralela o casi paralela al área aletada
del intercambiador de calor, aprovechando así el 100% de la superficie de intercambio de calor. The Adiabatic Cooling System type "V" is configured in such a way that the cooling panel or "pad" is in position "V" and accompanies parallel to the coils also arranged in "V", so that the cooling panels are in an arrangement parallel or almost parallel to the finned area of the heat exchanger, thus taking advantage of 100% of the heat exchange surface.
El sistema de enfriamiento adiabático cuenta con una estructura metálica (22) que consiste de un marco rectangular, una tubería de distribución que incluye una conexión de entrada de agua (1) conectada a un filtro (2), una válvula de solenoide (3) seguida de una conexión tipo "Tee" (4) donde el agua se deriva en dos flujos hacia cada uno de los paneles de enfriamiento o pads (9) de los serpentines (13), cada flujo de agua es regulado por medio de una válvula reguladora de flujo (5) correctamente calibrada para enviar la cantidad de agua que requiere el proceso a través del ramal de distribución (6), posteriormente el agua llega a un tubo distribuidor (7) que se encuentra en la parte superior del equipo y distribuye el agua a lo largo de los tubos de distribución (8) y posteriormente por gravedad el agua fluye a través de los paneles de enfriamiento (9) mojándolos al 100% en toda su superficie. The adiabatic cooling system has a metal structure (22) consisting of a rectangular frame, a distribution pipe that includes a water inlet connection (1) connected to a filter (2), a solenoid valve (3) followed by a "Tee" type connection (4) where water is derived in two flows to each of the cooling panels or pads (9) of the coils (13), each water flow is regulated by means of a valve Flow regulator (5) correctly calibrated to send the amount of water required by the process through the distribution branch (6), then the water reaches a distributor tube (7) that is located at the top of the equipment and distributes the water along the distribution tubes (8) and subsequently by gravity the water flows through the cooling panels (9) by wetting them 100% over their entire surface.
El sistema de enfriamiento adiabático cuenta con serpentines aleteados dispuestos en "V" sobre las guías de la estructura, definiendo una cámara interior triangular, y paneles de enfriamiento (9) de diferentes composiciones y configuraciones, preferentemente tipo panal de abeja (honeycomb), corrugados, de canales, de manera ilustrativa, más no limitativa ni a configuraciones ni a composiciones, dispuestos de forma paralela a los serpentines, cubriendo el área aletada de los serpentines también una posición en "V", de tal manera que los paneles de enfriamiento se encuentran en una disposición paralela a la cara aletada de los serpentines, aprovechando así el 100% de la superficie de intercambio de calor.
Además el sistema de enfriamiento cuenta con una cubierta (15) cerrando la cámara triangular, en donde se dispone de ventiladores (16), los cuales extraen el aire de la cámara triangular después de pasar a través de los serpentines atetados. The adiabatic cooling system has finned coils arranged in "V" on the guides of the structure, defining a triangular inner chamber, and cooling panels (9) of different compositions and configurations, preferably honeycomb type, corrugated , of channels, illustratively, but not limited to configurations or compositions, arranged parallel to the coils, covering the finned area of the coils also a "V" position, such that the cooling panels are they are in an arrangement parallel to the finned face of the coils, thus taking advantage of 100% of the heat exchange surface. In addition, the cooling system has a cover (15) closing the triangular chamber, where fans (16) are available, which extract the air from the triangular chamber after passing through the treated coils.
El flujo de aire inducido por los ventiladores (16) pasa a través de los paneles de enfriamiento (9), realizando la saturación del aire y como consecuencia la disminución de temperatura del aire muy cercana a la temperatura de bulbo húmedo, con este fenómeno la temperatura de entrada de aire disminuye por debajo del BS y por lo tanto la disipación de calor en las aletas del intercambiador se hace más eficiente. The air flow induced by the fans (16) passes through the cooling panels (9), performing the saturation of the air and as a consequence the decrease in air temperature very close to the wet bulb temperature, with this phenomenon the Air inlet temperature decreases below BS and therefore heat dissipation in the fins of the exchanger becomes more efficient.
El sistema de enfriamiento adiabático (ACS) de aire ambiente es un dispositivo que por medio de un proceso psicrométríco, se reduce la temperatura del aire atmosférico desde la temperatura de bulbo seco (BS) hasta unos 2 a 4 grados Centígrados por arriba de la temperatura de bulbo húmedo (BH) del lugar. The adiabatic cooling system (ACS) of ambient air is a device that, by means of a psychrometric process, reduces the temperature of the atmospheric air from the dry bulb temperature (BS) to about 2 to 4 degrees Celsius above the temperature of wet bulb (BH) of the place.
Este aire a temperatura muy cercana a la de bulbo húmedo (BH), cruza por el serpentín aleteado como medio condénsame o como medio de enfriamiento del fluido que circula dentro del serpentín atetado. This air at a temperature very close to that of a wet bulb (BH), crosses through the finned coil as a condensing medium or as a cooling medium for the fluid circulating inside the attached coil.
A1 entrar el aire al intercambiador a una temperatura más baja que la temperatura de BS, la capacidad del intercambiador se incrementa con respecto a su capacidad a temperatura de BS, o se podría tener una disminución del consumo de energía de los ventiladores, para esa misma capacidad nominal. Los paneles de enfriamiento (9), permiten mantener la superficie aletada seca del serpentín (13), por lo que es muy baja la posibilidad de acumulamiento de sedimentos minerales, minimizando el riesgo de obstrucción de aire y/o reducción de la vida útil del serpentín (13).
La estructura metálica del sistema de enf iamiento adiabático ACS tiene una configuración en posición de "V", que le permite ser instalado casi paralelamente a cada uno de los serpentines en forma de "V", de tal manera que los paneles de enfriamiento (9) se encuentran muy cerca del área aletada del intercambiador de calor, aprovechando al 100% la superficie de intercambio. When the air enters the exchanger at a temperature lower than the BS temperature, the capacity of the exchanger increases with respect to its capacity at BS temperature, or it could have a decrease in the energy consumption of the fans, for that same rated capacity. The cooling panels (9), keep the finned surface of the coil (13) dry, so the possibility of accumulation of mineral sediments is very low, minimizing the risk of air clogging and / or reducing the useful life of the coil (13). The ACS adiabatic cooling system metal structure has a "V" position configuration, which allows it to be installed almost parallel to each of the "V" shaped coils, such that the cooling panels (9 ) are very close to the finned area of the heat exchanger, taking full advantage of the exchange surface.
El sistema de enfriamiento adiabático, cuenta con charolas colectoras de agua (10) en el inferior del panel de enfriamiento (9), interconectadas por medio de la tubería de drenado (11), lo que permite tener solo una conexión de dren (12) en el condensador o enfriador. También cuenta con una válvula de purga (14) para evacuar el agua en caso de mantenimiento y/o cuando la temperatura ambiente esté a 4°C o menos, y evitar congelación de agua dentro de la tubería. The adiabatic cooling system has water collector trays (10) on the bottom of the cooling panel (9), interconnected by means of the drain pipe (11), which allows only a drain connection (12) in the condenser or cooler. It also has a purge valve (14) to evacuate water in case of maintenance and / or when the ambient temperature is 4 ° C or less, and avoid freezing of water inside the pipe.
Las ventajas del sistema de enfriamiento adiabático de tipo "V" son que con la configuración del pad y serpentín en la misma posición "V" y paralelas entre sí permiten un aprovechamiento del 100% de la superficie de intercambio, y que la misma posición paralela previamente descrita, el área de superficie de piso necesaria para instalar múltiples sistemas se reduce al menos 50%, sin que el rendimiento del sistema de enfriamiento se vea alterado. En una segunda modalidad, el sistema de enfriamiento de aire adiabático en posición "V" presenta un dispositivo para recirculación de agua (figura 5), un tanque (17) contenedor de agua de recirculación dispuesto en la parte frontal del sistema y conectado a las charolas (10) para recibir el agua proveniente de ellas, una tubería de recirculación (18) que se extiende desde el tanque (17) hasta la tubería de distribución (6), una bomba sumergible dispuesta dentro del tanque (17) para extraer
el agua, un sistema de control de nivel de agua (20) para determinar el nivel máximo y mínimo de agua dentro del tanque, y un panel de fuerza y control (21) el cual controla y o activa el sistema. The advantages of the "V" type adiabatic cooling system are that with the pad and coil configuration in the same "V" position and parallel to each other, they allow 100% use of the exchange surface, and that the same parallel position previously described, the floor surface area necessary to install multiple systems is reduced by at least 50%, without the performance of the cooling system being altered. In a second embodiment, the adiabatic air cooling system in position "V" has a device for water recirculation (figure 5), a tank (17) recirculating water container arranged in the front part of the system and connected to the trays (10) to receive water from them, a recirculation pipe (18) that extends from the tank (17) to the distribution pipe (6), a submersible pump arranged inside the tank (17) to extract water, a water level control system (20) to determine the maximum and minimum water level inside the tank, and a force and control panel (21) which controls and activates the system.
La configuración paralela entre el panel de enfriamiento y el serpentín sí se cumple en ésta modalidad. The parallel configuration between the cooling panel and the coil is fulfilled in this mode.
Como puede apreciarse en las figuras 6 y 7 es posible disponer una pluralidad de módulos de enfriamiento adyacentes entre si, ahorrando un espacio a nivel de piso aproximadamente de al menos 50% comparado con el de los sistemas de enfriamiento del estado de la técnica que presentan paneles verticales y por tanto al instalar sistemas múltiples, estos ocupan mayor espacio. As can be seen in Figures 6 and 7, it is possible to arrange a plurality of cooling modules adjacent to each other, saving a floor level space of at least about 50% compared to that of the state-of-the-art cooling systems that present Vertical panels and therefore when installing multiple systems, they take up more space.
En dichas figuras 6 y 7 se muestra como el área lateral se ve reducida, ya que los sistemas quedan solo un espacio mínimo "A" entre ellos, las flechas además indican como entra el aire a los sistemas de enfriamiento.
In said figures 6 and 7 it is shown how the lateral area is reduced, since the systems remain only a minimum "A" space between them, the arrows also indicate how the air enters the cooling systems.
