Soluciones de enfriamiento para el centro de datos<\/h1>\n

Las tecnolog\u00edas del centro de datos se est\u00e1n volviendo cada vez m\u00e1s compactas y potentes, lo que resulta en sistemas de mayor densidad que generan mayores cantidades de calor. Gesti\u00f3n del centro de datos<\/a> Los equipos constantemente encuentran nuevos m\u00e9todos para abordar el aumento en el consumo de energ\u00eda y la producci\u00f3n de calor para enfriar eficientemente el centro de datos. Las soluciones de enfriamiento actuales incluyen:<\/p>\n

Sistemas de enfriamiento que proporcionan eficiencia:<\/h2>\n

 <\/p>\n

Enfriador<\/strong>
\nUna enfriadora produce agua enfriada a trav\u00e9s del proceso de refrigeraci\u00f3n. El agua enfriada se entrega a trav\u00e9s de bombas a CRAH.<\/p>\n

 <\/p>\n

Aire acondicionado para sala de computadoras (CRAC)<\/strong>
\nUna unidad CRAC mueve aire a trav\u00e9s de sistemas de ventiladores en todo el centro de datos: entrega aire fr\u00edo a los servidores, devuelve el aire de escape de la habitaci\u00f3n.<\/p>\n


\nControlador de aire de la sala de computadoras (CRAH)<\/strong>
\nUna unidad CRAH mueve aire a trav\u00e9s de sistemas de ventiladores en todo el centro de datos: entrega aire fr\u00edo a los servidores, devuelve el aire de escape de la sala.<\/p>\n

 <\/p>\n

Free Cooling \/ Economizer<\/strong>
\nEsta unidad en particular utiliza el ambiente ambiental, t\u00edpicamente fuentes de aire fr\u00edo o agua, para aumentar o reemplazar el aire acondicionado mec\u00e1nico.<\/p>\n


\nHumidificador<\/strong>
\nUn humidificador generalmente se instala dentro de una unidad CRAC \/ CRAH y reemplaza la p\u00e9rdida de agua antes de que el aire salga de las unidades A \/ C.<\/p>\n


\n<\/strong>Refrigeraci\u00f3n l\u00edquida \/ complementaria<\/strong>
\nAl entregar l\u00edquido, ya sea agua refrigerada o refrigerante, m\u00e1s cerca de la fuente de calor, esta unidad puede ser m\u00e1s eficiente y efectiva cuando se trata de enfriamiento. A diferencia de una unidad CRAC, segregada en una esquina de una habitaci\u00f3n, estos aires acondicionados est\u00e1n integrados en una fila de racks de servidores, suspendidos del techo o instalados en una relaci\u00f3n cerrada con uno o m\u00e1s racks.<\/p>\n

No hay una respuesta definitiva sobre qu\u00e9 soluci\u00f3n de enfriamiento es la mejor o cu\u00e1l es la m\u00e1s eficiente, por lo que el equipo de administraci\u00f3n del centro de datos debe realizar un an\u00e1lisis de ingenier\u00eda detallado que analice de cerca los potenciales de diferentes estrategias y sistemas de enfriamiento de aire para cada situaci\u00f3n \u00fanica.<\/p>\n

Segregaci\u00f3n del flujo de aire y barreras<\/h3>\n

Pasillo caliente \/contenci\u00f3n de pasillo fr\u00edo<\/a> La configuraci\u00f3n es la pr\u00e1ctica de configurar bastidores para que las entradas de los bastidores se encuentren en un pasillo fr\u00edo com\u00fan que es suministrado por el sistema de enfriamiento y los gases de escape soplar\u00e1n en un retorno de pasillo caliente com\u00fan que vuelve al sistema de enfriamiento.<\/p>\n

La clave para la segregaci\u00f3n del flujo de aire es evitar que el suministro fr\u00edo de aire se mezcle con el aire caliente que se devuelve. Luego entregando el volumen requerido de flujo de aire. Colocar barreras encima y debajo de los gabinetes, aislar los pasillos calientes de los pasillos fr\u00edos es uno de los mejores enfoques para evitar que se mezclen el aire fr\u00edo y el aire caliente. Esta t\u00e9cnica reduce significativamente ambos tipos de flujo de aire, la cantidad de aire caliente que se infiltra en el pasillo fr\u00edo (re-arrastre) y el aire fr\u00edo que sale directamente del piso y difunde el retorno a trav\u00e9s de las rejillas de aire (derivaci\u00f3n). La siguiente figura muestra el flujo de aire y las temperaturas cuando no hay barreras.<\/p>\n

Pisos elevados<\/h3>\n

Algunos dise\u00f1os de centros de datos usan pisos elevados para distribuir aire fr\u00edo a trav\u00e9s del piso elevado a los bastidores del servidor. Pero solo se puede hacer mucho, por lo que tratar de empujar demasiado aire debajo del piso puede crear presiones negativas que en realidad pueden atraer el aire fr\u00edo hacia abajo a trav\u00e9s de las baldosas perforadas, en lugar de forzarlo hacia la habitaci\u00f3n. Adem\u00e1s, las baldosas tienen l\u00edmites en cuanto a la cantidad de aire que realmente puede pasar a trav\u00e9s de las perforaciones. En consecuencia, aumentar la capacidad de enfriamiento no necesariamente dar\u00e1 como resultado un aumento correspondiente en el enfriamiento a trav\u00e9s de la habitaci\u00f3n.<\/p>\n
