Novel Torque Ripple Minimization Control For 25 MW Variable Speed Drive System Fed By Multilevel Voltage Source Inverter
(Texas A&M University. Turbomachinery Laboratories, 2010)
Continuous improvements in the power rating and switching characteristics of power semiconductor devices have enabled the use of power electronics converters in high power variable speed drives (VSDs). These multimegawatt ...
Attributes of Indoor Environmental Quality to Earth-sheltered Building Design
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
This paper discusses the environmental attributes to underground building shape and configuration, materials, structures, use, maintenance, lighting, occupancy, and management. These criteria are hypothesized to be of more ...
Evaluation and Analysis of an Integrated PEM Fuel Cell with Absorption Cooling and Water Heating System for Sustainable Building Operation
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
In this paper, a parametric study of a PEM fuel cell integrated with a double effect absorption system is carried out in order to study the effect of different operating conditions on the efficiency of the PEM fuel cell, ...
Solar Energy to Drive Absorption Cooling Systems Suitable for Small Building Applications
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
Air conditioning systems have a major impact on energy demand. With fossil fuels fast depleting, it is imperative to look for cooling systems that require less high-grade energy for their operation. In this context, ...
The Contemporary Architecture Design for the Housing Green Buildings and its Role in Saving Energy in the Arab City
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
In the Arab cities the housing buildings is to be exposed to the sun-hot rays specially in the summer, which is effected on peoples indoors and outdoors. Therefore, many peoples used Air conditioning apparatus to have the ...
Evaluation on Cooling Energy Load with Varied Envelope Design for High-Rise Residential Buildings in Malaysia
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
With the development of the economy in the recent years, Malaysia is maintaining a high economic growth and therefore, its energy consumption increases dramatically. Residential buildings are characterized by being ...
Experimental Investigation of the Effect Of Zeolite Coating Thickness on the Performance of a Novel Zeolite-Water Adsorption Heat Pump Module
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
A novel zeolite-water absorption heat pump module comprising an adsorber, an evaporator and a condenser heat exchanger as well as a module non-return valve in a hermetically sealed vessel is introduced. The investigated ...
Enhancing Residential Building Operation through its Envelope
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
In this study heat loss is evaluated with the modeling software of Iranian Construction Engineering Organization, for both with and without insulation in the building. Of course the evaluation is in accordance with the ...
Testing a Prototype Adsorption Cooler in a Research Dwelling
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2010)
Cooling with heat is hot. Demand for cooling often coincides with the supply of solar heat. This makes thermally driven chillers (TDC's) in combination with solar collectors interesting for improving the energy efficiency ...
