Abstract
Data Centers energy consumption has been increasing in alarming rates all around the world. The cooling system is responsible for about 40% of this electricity demand. An effective solution for this problem is the free cooling operation. This paper has analyzed the Data Center free cooling potential of 14 capitals cities from Brazil based on ASHRAE Thermal Guidelines climate ranges using Test Reference Year (TRY) weather data. Two climate parameters have been selected to define the free cooling zones on a psychrometric chart: upper Dry-bulb temperature and upper Dew-point temperature. The results have shown that cities such as Curitiba, São Paulo, Porto Alegre and Brasília have high potential to free cooling usage being able to operate in a compressor-less cooling for more than 3000 hours in a year, even when considering the most restrictive operation range. The North and Northeast region of the country have only presented viability of free cooling usage when considering the most flexible ranges. Furthermore, results have shown that the critical parameter to assess free cooling potential in Brazilian capitals is the Dew-point temperature.
