(Texas A&M University, 1995-12)Particle deposition in contraction fittings with half-angles of 12 degrees, 45 degrees, and 90 degrees; expansion fittings with half-angles of 3 degrees, 6 degrees, 12 degrees, 45 degrees, and 90 degrees; and ...
-
(Texas A&M University, 1993-12)Approximately 3% of the United States' commercial building energy consumption is attributable to food sales facilities. Although this is one of the smallest consumption percentages, it is still significant, amounting to ...
-
(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 ...
-
(Texas A&M University, 2007-04-25)This dissertation provides one methodology to determine potential energy savings of buildings with limited information. This methodology is based upon the simplified energy analysis procedure of HVAC systems and the control ...
-
(Texas A&M University, 1995-05)This dissertation develops Fourier series and Artificial Neural Network (ANN) approaches to model hourly energy use in commercial buildings and illustrates application to data-screening. The procedure for modeling hourly ...
-
(Energy Systems Laboratory, 2000-08)To quantify the measurement error of slow meters in the developing length, simulation model development, local velocity measurements, flowmeters test, and regression model development were carried out for 10.2 cm, 15.2 cm, ...
-
(Texas A&M University, 1995-08)The present work is concerned with developing a discretized analytical model to investigate the effect of a backfill on the performance of a vertical U-tube ground-coupled heat pump. This work involves the development ...
-
(Texas A&M University, 1988-12)A study on the effects of frost growth on the performance of finned tube heat exchangers under laminar flow has been conducted. The study was both experimental and analytical. The experimental part of the investigation ...
-
(Texas A&M University, 1995-12)The effects of hydrophobic coatings on the dropwise condensation process for a flat horizontal copper plate held at a temperature much lower than the surrounding air was investigated. Extensive qualitative and quantitative ...
-
(Texas A&M University, 1993-08)The work described in this report was performed under the direction of the Energy Analysis and Diagnostic Center (EADC) at Texas A&M University. The EADC program is managed by University City Science Center under agreement ...
-
(2022-11-09)A significant portion of energy consumption occurs in buildings today. Accurate and easy-to-implement methods are needed to calculate building energy consumption for a wide range of applications, including efficiency ...
-
(Texas A&M University, 1999-05)This dissertation provides a simple yet powerful approach, the fully layered inverse bin method, to baseline hourly energy use in commercial buildings and illustrates the application through carefully ...
-
(Texas A&M University, 1996-05)The heat transfer and the freezing process of condensate droplets resting on a cold metal plate have been studied both experimentally and numerically. The experimental part of the investigation dealt with the measurements ...
-
(Texas A&M University, 1991-05)Infiltration is customarily assumed to increase the heating and cooling load of a building by an amount equal to the mass flow rate of the infiltration times the enthalpy difference between the inside and outside air - ...
-
(Texas A&M University, 2006-04-12)Typical energy audits are sufficiently expensive and time-consuming that many owners and managers of buildings are not willing to invest the time and money required for a full audit. This dissertation provides a methodology ...
-
(Energy Systems Laboratory, 2000-08)Single-phase flow of refrigerants R-22, R-13a, and R-41a through flexible short tube orifices with three different geometries and a range in upstream operating conditions was modeling using the finite element method, FEM. ...
-
(Texas A&M University, 1992-11)This report presents results from degraded performance measurements of a residential air conditioning system operating under reduced evaporator air flow. Experiments were conducted using a R-22 three-ton split-type cooling ...
-
(Texas A&M University, 1995-08)This report describes an investigation of energy use at various LoanSTAR sites. The effects of installing Energy Management Control Systems (EMCS) on electricity consumption was studied at four LoanSTAR sites: Stroman ...
-
(Texas A&M University, 1999-08)Proportional and Integral (PI) controllers are used widely in HVAC applications. It is necessary to choose suitable values for PI gains for PI control of the heating and cooling coils in buildings. Consequently, suitable ...
