(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 ...
-
(2007-12)A distributed parameter approach for dynamic modeling of heat exchangers and using it to obtain low order models have been presented in this report. The finite control volume (FCV) approach accurately captures the distributed ...
-
(Texas A&M University, 1999-12)This record of study takes a firsthand look at corporate research and development efforts to improve the damage tolerance of two unique composite materials used in high performance aerospace applications. The professional ...
-
(Energy Systems Laboratory, 2001-05)The Short-term Monitoring Long-term Prediction (SMLP) method is a new method for baselining, predicting and evaluating the energy performance of commercial and institutional buildings when only short-term data are available. ...
-
(Energy Systems Lab, 2004-05)
-
(1992-08)The influence of heat recovery on the energy impact of air infiltration, and the systematic error due to the steady-state method were studied both experimentally and theoretically. Two methodologies suitable for measurement ...
-
(Texas A&M University, 2000)To define a single technique that can be reliably used for evaluation of missing data in time series of weather and building energy use data is a complex task. This thesis evaluates the application of spline and Fourier ...
-
(2020-12)Occupant behavior has a significant influence on energy consumption in buildings because HVAC, lighting, equipment, and ventilation operations are often tied to occupancy- based controls. However, currently, the traditional ...
-
(1989-12)An experimental and analytical study concerned with the transient performance of heat pumps is presented. A series of tests were performed to study and characterize the transient sensible and dehumidification performance ...

(2008-01-23)HCFC-22 and HFC-134a were used with short tube orifices having length to diameter ratios ranging from 5 to 20 in a 9.53 mm (3/8 in.) refrigerant line to investigate both two-phase and subcooled liquid flow entering the ...
-
(Energy Systems Laboratory, 2007-05)Numerous fault detection and diagnostic system techniques have been developed for HVAC systems, but most focus on detecting faults at the component level, for example, air handling units or variable air volume boxes. ...
