Research on efficiency of air conditioning system for data-center

Now, as we move toward the advanced information society, systems for transmitting multimedia information, including text, sound, video, and computer data, play the vital role in society. Particularly, the Internet, which enables us to get information all over the world, has spread remarkably and adopted broadband communication systems. Servers and routers supporting these networks are set up in data-centers, which are necessary for information relay. Air conditioning systems are introduced in data-centers for the smooth operation of machines and to maintain the information systems environment. In the case of the heat distribution in the room, the operating temperature of the air conditioning system should be lowered so that the hottest machines don't exceed the appropriate temperature. In this case the operation is not efficient. Thus, the distribution of heat generation is one of the factors that affects the efficiency of air conditioning systems. The author studied the relation between heat distribution and energy consumption of air conditioning systems. The result of this research is expected to assist in the arrangement of the air conditioning system in a data-center. In the laboratory, there are a lot of machines that can change heat generation. The room temperature and the efficiency of air conditioning system were measured and the result showed that heat generation affects energy consumption.
