Abstract
El incremento de aplicaciones que requieren de una elevada capacidad de cómputo,
ha provocado la creación de nuevos centros de datos, incrementando la cantidad de servidores
necesarios para ofrecer soporte a un gran número de usuarios. El crecimiento del
número de centros de datos conlleva un aumento de la energía demandada, tanto para los
equipos dedicados al procesamiento y almacenamiento de datos como para la refrigeración
de los mismos.
Este aumento de la potencia requerida no es sostenible y, genera la necesidad de mejorar
la eficiencia energética mediante nuevos sistemas de refrigeración, capaces de mejorar
los consumos de suministro eléctrico, generación de calor y rendimiento.
La implementación de los sistemas de refrigeración mediante el uso de hidro-fluoroéteres,
ofrecen una solución prometedora a los problemas que conlleva el aumento del
consumo que requieren los centro de datos ante las nuevas necesidades.
En este trabajo se diseñan y desarrollan unos prototipos dedicados a la generación de
calor controlada, que puedan ser sumergidos en el líquido y que sirvan para el estudio de
las capacidades del mismo. Permiten monitorizar la temperatura alcanzada por el líquido,
con el objetivo de averiguar su capacidad de arrastre de calor, así como obtener su curva
característica.
Se explican detalladamente todas las etapas requeridas para la obtención del prototipo,
incluyendo el diseño hardware y el software embebido en el microcontrolador. Por último,
una vez montados los prototipos se realizan una serie de experimentos encaminados a
mostrar las bondades del líquido y a probar que el prototipo desarrollado sirve para su
propósito.
Due to the increasing number of applications demanding high processing capabilities, the creation of new data centers has increased dramatically as it has increased the number of servers required to provide such applications to users. The growth in the number of data centers involves a rise in the demanded energy to supply both the equipment dedicated for processing and storing data and the cooling system. This rise of the power required is not sustainable and, generates the need of improving the energy efficiency by means of new refrigeration systems able to reduce the consumption of power, the heat generation and to improve performance. The implementation of refrigeration systems using hydro-fluoro-ethers offers a promising solution to problems related to the increase of power consumption in data centers when facing the new needs. This work is focused in the design and development of dedicated prototypes which are able to generate heat in a controlled way and to be submerged in the fluid so they can be used for studying the characteristics of the fluid. They allow fluid temperature monitorization with the aim of finding out its heat drag capacity, as well as obtaining its characteristic curve. All the phases required to obtain the prototype are explained in detail, including hardware design and a description of the software embedded in the microcontroller. Finally, once the prototypes are assembled, different experiments are carried out to show some benefits of the fluid and to prove that the developed prototype fulfills its purpose.
