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 ...
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, ...
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 ...
Field Performance of a Ground-Coupled Heat Pump in Abilene, Texas
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1994)
A nominal 10.6 kW (3 ton), vertical-configuration
ground-coupled heat pump was
installed in Abilene, Texas in December 1989
and was monitored until May 1993 using a
remote data acquisition system. The unit was
installed ...
