The growing demand for electricity and the increasing size of the carbon footprint of data centers worldwide bring a severe challenge to sustainable development of human civilization. The cooling energy consumption takes up around 30–50% of the total consumption of data centers due to the...

The provision of low cost cooling is challenging due to high energy costs and increasing heat dissipation volumes from data centers. In Australia, with the introduction of emissions trading scheme, the cost of energy with carbon origin is expected to increase. In order to reduce cooling costs,...

Over the past decade, digital connectivity has emerged as a critical new form of infrastructure, akin to roads, energy or ports-underpinning economic growth and social development. In Papua New Guinea (PNG), the advent of digital connectivity has opened up new avenues for communication,...

The Integrated Government Information System (IGIS) is a private government network comprising several components such as records and data management services, government email, civil registration, the IGIS portal, IGIS data center & disaster recovery center, IGIS network, and a project...

The dynamic evolution of granular gases is fundamentally different from molecular gases due to the energy loss during collisions. Nevertheless techniques of kinetic theory are useful in a regime, when the granular particles are moving rapidly and the gas is sufficiently dilute. In these lecture...

In this paper, the optimization of a weather-predicted free cooling system combined with heat storage is shown. The method of incorporating weather forecasts into the control system is presented. The regime of operation was selected and optimized based on free cooling energy and the required...

Latent heat thermal storage (LHTS) is a technology that can help to reduce energy consumption for cooling applications, where the cold is stored in phase change materials (PCMs). Free cooling is a concept developed for air conditioning applications, in which coolness is collected from ambient...
