Development of a Transient Heat and Mass Transfer Model of Residential Attics to Predict Energy Savings Produced by the Use of Radiant Barriers
(Energy Systems Laboratory (http://esl.tamu.edu), 1992-12)
A transient heat and mass transfer model was developed to predict ceiling heat gain/loss through the attic space in residences and to accurately estimate savings in cooling and heating loads produced by the use of radiant ...
Numerical Modeling of the Transient Thermal Interference of Vertical U-Tube Haet Exchangers
(1994-12)
Non-linear finite element models were developed to simulate transient heat and mass transfer in the soil surrounding the ground heat exchangers of ground-coupled heat pumps (GCHPs) operating in the cooling mode. Parametric ...
An Experimental Investigaton of the Effect of Oil on Convective Heat Trasfer and Pressure Drop of a HFC-32/HRC-125 Mixture
(1994-12)
The heat transfer coefficients and pressure drops of HCFC-22 and a 50% mass mixture of HFC-32/HFC-125 were experimentally measured under flow boiling conditions in a smooth tube. The refrigerants were flowed through an 8 ...
Analysis of Mass Flow and Enhanced Mass Flow Methods of Flashing Refrigerant-22 from a Small Vessel
(1994-12)
The mass flow characteristics of flashing Refrigerant-22 from a small vessel were investigated. A flash boiling apparatus was designed and built. It was modeled after the flashing process encountered by the accumulator of ...
Effects of Hydrophobic Surface Treatments on Dropwise Condensation and Freezing of Water
(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 ...
An Investigation on Heat Transfer During the Freezing of Condensate Droplets
(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 ...
An Analysis of the Benefits of Photovoltaic-coated Glazing on Owning and Operating Costs of High Rise Commercial
(Texas A&M University, 1999-12)
Energy efficient glazing is necessary to reduce heat gains or losses that contribute to the high-energy use of buildings. However, high-rise commercial buildings that use energy efficient glazing are still consumptive. ...
The Measured Energy Impact of Air Leakage on Frame Wall Systems
(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 - ...
Energy Conservation Opportunities in Commercial and Industrial Facilities: Energy Utilization Indices (EUI) in Texas LoanSTAR Buildings
(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 ...
Effect of Backfill on the Performance of a Vertical U-Tube Ground Coupled Heat Pump
(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 ...
