Performance Evaluation of Reverberant Chamber Background Noise Levels
(2012-02-14)
An improved test system for acoustical rating of air-movement devices was installed
and evaluated at the Riverside Energy Efficiency Laboratory at Texas A&M University
where measurements of sound pressure levels ...
Modeling Building Energy Use and HVAC Efficiency Improvements in Extreme Hot and Humid Regions
(2011-10-21)
An energy analysis was performed on the Texas A & M University at Qatar building in Doha, Qatar. The building and its HVAC systems were modeled using EnergyPlus. Building chilled water and electrical data were collected ...
Development of Models for Series and Parallel Fan Variable Air Volume Terminal Units
(Texas A&M University, 2007-09-17)
Empirical models of airflow output and power consumption were developed for
series and parallel fan powered variable air volume terminal units at typical design
pressure conditions. A testing procedure and experimental ...
Flat Oval Spiral Duct Deflection
(2014-03-10)
The deflection of a spiral duct depends on its flat span, gauge, pressure, and reinforcement. Furthermore, the duct weight determines the cost of installation, not only in material costs but also labor, which is bid by the ...
Development of an Automated Fault Detection and Diagnostic Tool for Unitary HVAC Systems at Industrial Energy Audits
(2014-10-30)
Industrial energy audits generally focus on optimization of manufacturing process systems but fail to focus on the non-process industrial HVAC systems. This is in spite of the well-documented widespread prevalence of ...
Active Remote Setpoint Optimization Utilizing BAS Trend Data
(2017-12-06)
In this work, a new concept was explored for the optimization of heating, ventilating,
and air-conditioning (HVAC) systems in buildings. The methods assume that
only commonly trended sensor data would be available and that ...
Improving Refrigeration Cycle Efficiency by Evaporative Precooling the Condenser Inlet Air
(2017-11-30)
The need to improve the energy performance of Heating, Ventilation & Air Conditioning (HVAC) units has always been a primary goal for designers as they implement new concepts and/or modifications to the standard vapor ...
Analysis of Innovative HVAC System Technologies and Their Application for Office Buildings in Hot and Humid Climates
(2012-02-14)
The commercial buildings sector in the United States used 18 percent (17.93 Quads) of the U.S. primary energy in 2006. Office buildings are the largest single energy consumption category in the commercial buildings sector ...
A Thermal RC Model Including Thermal Mass and Solar Gain Effects for Building Energy Simulation
(2019-10-30)
Building Commissioning is important for evaluating energy and dollar savings in existing buildings. Energy Systems Lab of Texas A&M University has developed WinAM with the purpose of aiding that process. WinAM is a ...
Thermodynamic Modeling of a Membrane Dehumidification System
(2012-11-28)
In warm and humid climates, a primary source of building energy consumption is dehumidification of conditioned air supplied to the building spaces. The proposed system utilizes a selective membrane to remove water vapor ...
