Medina, M. A.; Turner, W. D.; O'Neal, D. L. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1994)This paper presents simulated performance of insulation/radiant barrier systems under different Texas climates. A transient heat and mass transfer model which predicts thermal performance of residential attics (Medina, ...

Ashley, R.; Garcia, O.; Medina, M. A.; Turner, W. D. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1994)The objective of the study was to experimentally evaluate the performance of radiant barriers in single-family occupied housing units in South Texas. Ceiling heat fluxes, attic air temperatures, indoor air temperatures, ...

Medina, M. A.; O'Neal, D. L.; Turner, W. D. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)Results of side-by-side radiant barrier experiments using two identical 144 ft2 (nominal) test houses are presented. The test houses responded very similarly to weather variations prior to the retrofit. The temperatures ...

Medina, M. A.; Elkassabgi, Y. (Energy Systems Laboratory (http://esl.tamu.edu), 1995-04)An Energy Analysis and Diagnostic Center was established at Texas A&M University-Kingsville (formerly Texas A&I University) in November 1993 by the U.S. Department of Energy. The Center is managed by the University City ...

Medina, M. A.; Elkassabgi, Y.; Farahmand, K.; Bhalavat, M. (Energy Systems Laboratory (http://esl.tamu.edu), 1997-04)An Industrial Assessment Center (IAC) was established at Texas A&M University-Kingsville in November 1993 by the U. S. Department of Energy. The Center is managed by the University City Science Center, located in Philadelphia, ...

Figueroa, I. E.; Cathey, M.; Medina, M. A.; Nutter, D. W. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1998)This paper presents modifications made to the procedure used to develop a universal thermodynamic model of chillers (Gordon and Ng, 1995). The modifications were necessary to capture physical phenomena involved when water ...

Zhang, M.; Medina, M. A.; King, J. B. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2004)The main purpose of this work was to develop a thermally enhanced frame wall that would reduce peak load air conditioning demand, shift a portion of the thermal load, and conserve energy in residential buildings. A frame ...

Figueroa, I. E.; Cathey, M.; Medina, M. A.; Nutter, D. W. (Energy Systems Laboratory (http://esl.tamu.edu), 1998-04)This paper presents two case studies in which thermodynamic modeling was used to predict improved chiller performance. The model predicted the performance (COP and total energy consumption) of water-cooled centrifugal ...

Medina, M. A.; O'Neal, D. L.; Turner, W. D. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)Results of winter experiments conducted in Central Texas are presented. The experiments were side-by-side tests using two identical 144 ft2 houses which responded similarly to weather variations prior to any retrofits. Two ...
