Potential of air-side economizers for data center cooling: A case study for key Australian cities

Overview of direct air free cooling and thermal energy storage potential energy savings in data centres

“…But in the zones with lower dew point temperatures such as very-cold and cold-dry climate zones, the power and water consumed by the humidification system can be important and they should be accounted. In a similar study, Siriwardana et al [10] investigated the use of direct air free cooling in different Australian climate conditions. They highlighted that there is a potential use of this strategy in some states that could lead to significant energy saving and thus CO 2 mitigation.…”

“…But Shehabi et al [6] [7] showed that staying below the ASHRAE recommended particulate contaminant concentration for data centres can be accomplished with proper filtration. Many researchers have examined the potential of free cooling for different infrastructures such as office buildings [8], commercial buildings [9] and more recently data centres [1] [10]. Lee and Chen [1] used a dynamic building energy simulation program to examine the potential energy saving of using direct air free cooling in data centres for 17 climate zones.…”

Experimental investigation and economic analysis of gravity heat pipe exchanger applied in communication base station

“…Communication base station is a special building which dissipates heat almost all year round [11]. The air conditioning system used in the communication base station would have large operating energy consumption.…”

Heat pipe based thermal management systems for energy-efficient data centres

“…Other energy data from around the world report similar findings where these centres were found to consume many time higher than department stores, commercial buildings, and other high-energy consuming installations. Therefore, the utilisation of free cooling opportunities to reduce the energy cost and greenhouse gases emissions is a must-have if the climate conditions are suitable [10].…”
