Effects of Radiant Barrier Systems on Ventilated Attics in a Hot and Humid Climate
(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 ...
A Simplified Procedure for Sizing Vertical Ground Coupled Heat Pump Heat Exchangers for Residences in Texas
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1994)
A simplified technique for the sizing of vertical
U-tube ground coupled heat pump (GCHP) heat
exchangers for Texas climates was developed
utilizing a transient simulation model of a ground
coupled heat pump and weather and ...
Effect of Return Air Leakage on Air Conditioner Performance in Hot/Humid Climates
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1996)
An experimental study was conducted to quantify the
effect of return air leakage from hot/humid attic
spaces on the performance of a residential air
conditioner. Tests were conducted in psychrometric
facilities where ...
Program Overview: The Texas LoanSTAR Program; 1989-August 1997
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
The Texas LoanSTAR mans to Save Taxes
and Resources) program was conceived as a $98.6
million capital retrofit program for building energy
efficiency. The funding source is petroleum violation
escrow funds (PVE) from the ...
Economic Evaluation of Insulation/Radiant Barrier Systems for the State of Texas
(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, ...
The Impact of Residential Air Conditioner Charging and Sizing on Peak Electrical Demand
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
Electric utilities have had a number of air conditioner rebate
and maintenance programs for many years. The purpose of
these programs was to improve the efficiency of the stock of
air conditioning equipment and provide ...
Analysis of Texas LoanSTAR Data
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1990)
The analysis effort during the first year of the Texas LoanSTAR
Monitoring and Analysis Program has emphasized selection and
development of baseline analysis techniques to cover the range
of buildings expected in the ...
A Modified Analytical Method for Simulating Cyclic Operation of Vertical U-Tube Ground-Coupled Heat Pumps
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1994)
A modified analytical model is presented which discretizes the ground-coupled heat exchanger of a ground-coupled heat pump and utilized a separate cylindrical source solution for each element. First law expressions are ...
Two-Phase Flow of Two HFC Refrigerant Mixtures Through Short Tube Orifices, Draft Final Report
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1994)
The present study presents data for flow of two refrigerant mixtures through short tube orifices. The two mixtures were R3211251134a (23%/25%/52% on a mass percentage basis) and R321125 (50%/50%). The following presents ...
Effect of a 90° Elbow on the Accuracy of an Insertion Flowmeter, Results and Comparisons for 4 and 6 in. Diameter PVC Pipe
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1996)
Thermal energy consumption in buildings with
chilled or hot water distribution systems is often
monitored through the use of some type of flow
metering device. These flowmeters can be fixed types,
such as venturis or ...
