Decentralized Model Predictive Control of a Multiple Evaporator HVAC System
(2009-05-15)
Vapor compression cooling systems are the primary method used for
refrigeration and air conditioning, and as such are a major component of household and
commercial building energy consumption. Application of advanced control ...
Performance of ECM Controlled VAV Fan Powered Terminal Units
(2009-05-15)
Empirical performance models of fan airflow, primary airflow and power consumption were
developed for series and parallel variable air volume fan powered terminal units. An
experimental setup and test procedure were created ...
Use of Autoassociative Neural Networks for Sensor Diagnostics
(Texas A&M University, 2005-02-17)
The new approach for sensor diagnostics is presented. The approach, Enhanced Autoassociative Neural Networks (E-AANN), adds enhancement to Autoassociative Neural Networks (AANN) developed by Kramer in 1992. This enhancement ...
A Comparison of Commissioning Savings Determination Methodologies and the Persistence of Commissioning Savings in Three Buildings
(2009-05-15)
This thesis compares the variability of commissioning savings and the persistence of
savings from the Normalized Annual Consumption (NAC) and standard International
Performance Measurement and Verification Protocol (IPMVP) ...
Hydraulic Modeling of Large District Cooling Systems for Master Planning Purposes
(Texas A&M University, 2007-09-17)
District Cooling Systems (DCS) have been widely applied in large institutions such
as universities, government facilities, commercial districts, airports, etc. The hydraulic
system of a large DCS can be complicated. They ...
Industrial Energy Use Indices
(2009-05-15)
Energy use index (EUI) is an important measure of energy use which normalizes
energy use by dividing by building area. Energy use indices and associated coefficients
of variation are computed for major industry categories ...
Natural Convection and Radiation in Small Enclosures with a Non-Attached Obstruction
(Texas A&M University, 2004-09-30)
Numerical simulations were used to investigate natural convection and radiation interactions in small enclosures of both two and three-dimensional geometries. The objectives of the research were to (1) determine the ...
Systematic Time-Based Study for Quantifying the Uncertainty of Uncalibrated Models in Building Energy Simulations
(Texas A&M University, 2005-07-27)
This thesis documents the usefulness and accuracy of uncalibrated simulations to determine for what end-uses these simulations should be used. The study was divided into three segments 1)comparison of the accuracy of two ...
Development and Implementation of an Artificially Intelligent Search Algorithm for Sensor Fault Detection Using Neural Networks
(Texas A&M University, 2004-09-30)
This work is aimed towards the development of an artificially intelligent search algorithm used in conjunction with an Auto Associative Neural Network (AANN) to help locate and reconstruct faulty sensor inputs in control ...
Interactive graphical timelines as collaborative scenario management tools
(Texas A&M University, 2008-10-10)
Training emergency response decision makers using live, virtual and/or constructive
simulations can be highly complex since certain situations can generate stimulusresponse
cycles that depend significantly on unpredictable ...
