A simulation-based assessment of humidity treatment in data centre cooling systems with air-side economisers Simulační posouzení úpravy vlhkosti v systémech chlazení data center s ekonomizérem na straně vzduchu

Popis výsledku v původním jazyce

The increasing digitalization of data is resulting the need for ever greater computational capacity, which in turn is leading to increasing energy consumption of data centers. A large percentage of this energy use arises from the need to mechanically remove an enormous amount of heat from the datacenter environment. In fact, in current practice, the mechanical infrastructure (especially cooling systems) of the data center accounts for up to half of the overall energy consumption. To reduce the energy consumption of mechanical infrastructure, several economization methods are commonly implemented in cooling systems, one of which is the application of a direct air-side economizer addressed in the current research. The use of an air-side economizer has been shown to lead to major savings of cooling electricity demand, and as such it has been widely used as a necessary addition to conventional cooling systems. This study analyses the energy breakdown of data center cooling systems that include an air-side economizer in order to determine which components within the system are responsible for major energy consumption. This study investigates, via computational simulation, the impact of the use of a conventional cooling system and system with an air-side economizer on total energy demand in three locations representing different climate regions in Europe. The study is especially focused on energy demand related to humidity treatment in the datarooms, since yet the effect is rarely considered into the overall DC energy balance. The results demonstrate, as expected, that the air-side economizer can yield major savings of around 62.5% to 78.7%, depending on the given climate regions. However, the key result of this study is that the humidity treatment necessary for the direct air-side economizer system may consume up to 34.8% of the total energy demand of the cooling system with the air-side economizer.
