Energy and Exergy Analysis of Modular Data Centers

Achieving both Energy-Efficiency and Reliability in Modular Data Centers

It has been shown that supply voltage changes have negative effect on soft error rate and therefore, in systems in which reliability is an important factor, reconsidering current voltage assignment techniques to make them reliability-aware is an important requirement. In this work we jointly investigate energy-efficiency and reliability issues in modular data centers that exploit Dynamic Voltag...

Architecture for Modular Data Centers

Large numbers of low-cost, low-reliability commodity components are rapidly replacing high-quality, mainframe-class systems in data centers. These commodity clusters are far less expensive than the systems they replace, but they can bring new administrative costs in addition to heat and power-density challenges. This proposal introduces a data center architecture based upon macro-modules of sta...

Exergy Analysis of Complex Ship Energy Systems

With multiple primary and secondary energy converters (diesel engines, steam turbines, waste heat recovery (WHR) and oil-fired boilers, etc.) and extensive energy networks (steam, cooling water, exhaust gases, etc.), ships may be considered as complex energy systems. Understanding and optimizing such systems requires advanced holistic energy modeling. This modeling can be done in two ways: The ...

Energy-Efficient Data Centers

the energy and exergy analysis of single effect absorption chiller

the first and second laws of thermodynamics have been employed to evaluate energy and exergetic efficiency of the single effect absorption chiller which is used for air conditioning purpose. the performance analysis has been carried out by developing a computer program in ees and modeling the chiller and its components. to evaluate entropy of the water/lithium bromide solution at any point, an ...
