Engineering and Software Requirements of the Automated Building Commissioning Analysis Tool (ABCAT)
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M University, 2005)
Engineering and Software requirements were measured using ABCAT
Variable Speed Drive (VSD) Applications in Dual-Duct Constant Volume Systems
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
Models have been developed for static pressure
and potential supply fan energy savings by using
variable speed drive (VSD) in dual-duct constant
volume systems. Experiments have been performed
using a full size dual-duct ...
Economizer Applications in Dual-Duct Air-Handling Units
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
This paper provides analytical tools and engineering methods to evaluate the feasibility of the economizer for dual-duct air-handling units. The results show that the economizer decreases cooling energy consumption without ...
Continuous Commissioning(SM) of a Thermal Storage System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2001)
Chilled water thermal storage systems can
reduce the electrical demand charge during the onpeak
months. However, operational problems such as
the inability to fully charge the system or premature
discharge of the stored ...
Development of In-Situ Fan Curve Measurement with One Airflow Measurement
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2003)
Fan airflow is the key parameter for air volume
tracking control in variable air volume systems. One
of the airflow measurement methods is to determine
airflow using the fan speed, fan head, and fan curve.
Both fan speed ...
Impacts of Static Pressure Reset on VAV System Air Leakage, Fan Power and Thermal Energy - Part 2: Case Demonstration for a Typical Climate System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
In Part 1 of this paper, the theoretical models, integrating the fan airflow, fan head, air leakage factors, are developed to analyze the impacts of the static pressure reset on both pressure dependent and pressure independent ...
Terminal Box Airflow Reset: An Effective Operation and Control Strategy for Comfort Improvement and Energy Conservation
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
A new terminal box operation and control
strategy, airflow reset, is developed to improve
building comfort and energy efficiency during
unoccupied and lightly occupied hours. The airflow
reset lowers the minimum airflow ...
The Office Air Handling Unit versus the Two Dedicated Air Handling Unit System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
Both analytical and the numerical methods have
been developed to compares the energy performance
of the OAHU systems and the two-AHU (TAHU)
system. The OAHU system saves up to 1.85
kilojoules heating energy for each kilogram ...
Optimal Airflow Control for Laboratory Air Handling Unit (LAHU) Systems
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
An optimal airflow control method and procedure have been developed for laboratory air handing unit (LAHU) systems using linear optimization theories. The optimal airflow control minimizes the thermal energy consumption ...
Optimization of Multi-Stack Exhaust Systems - New System Design Application
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
Both analytical and numerical optimization
methods have been developed to optimize multi-stack
exhaust systems for application in new system
designs. In these systems the combined airflow
capacity of the stacks equals the ...
