RISPhase Change Material Freezing in an Energy Storage Module for a Micro Environmental Control System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study analyzes phase change material (PCM) freezing process in a novel latent heat storage device (LHSD). Heat is removed from the PCM with an embedded evaporator. A mathematical model of freezing in a finite-thickness ...
Phase Change Material Melting in an Energy Storage Module for a Micro Environmental Control System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimentally validated finite element model (FEM) was developed to analyze the design parameters of a latent heat storage device (LHSD) for a micro environmental control system (μX). The μX provides local cooling to ...
Thermally Aware, Energy Based Load Placement in Open Aisle, Air Cooled Data Centers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces a methodology for developing a reduced order model, using proper orthogonal decomposition (POD), to predict the IT rack's inlet temperature distribution within a raised floor aircooled data center. ...
Expanded Assessment of a Practical Thermally Aware Energy Optimized Load Placement Strategy for Open Aisle, Air Cooled Data Centers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper expands on the work presented by Demetriou and Khalifa (Demetriou and Khalifa, 2013, “Thermally Aware, EnergyBased Load Placement in OpenAisle, AirCooled Data Centers,†ASME J. Electron. Packag., 135(3), p. ...
Determination of the Lumped Capacitance Parameters of Air Cooled Servers Through Air Temperature Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computer servers can be represented by lumped thermal capacitances for the purpose of simulating server and data center transient thermal response to changes in operating conditions or equipment failures. Two parameters ...
