Demand-based Optimal Control to Save Energy: A Case-Study in a Medical Center
(Energy Systems Laboratory, 2008-12)
Continuous Commissioning®1 (CC®) strategies include reducing simultaneous heating and cooling, scheduling the facility’s occupancy needs, utilizing free cooling, and minimizing excessive supply air and outside air. Most ...
Optimal Control in Three-deck Multi-Zone Air-Handling Units: A Case-Study
(Energy Systems Laboratory, 2008-12)
A multi-zone air-handling unit was popular several decades ago due to the convenience of small sized modular units, which were inexpensive to install and easily maintained in a mechanical room. The cost and convenience ...
Simulation and Optimization on Power Plant Operation Using Sega's EOP Program
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
The operation of a cogeneration power plant is
complicated. The Energy Optimization Program
(EOP, software made by SEGA, Inc.) was designed
to simulate and optimize the operation of TAMU
power plant. All major plant ...
Commissioning of A Large Office Building in Texas - A Case Study
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
This case study involves commissioning of a
large office building in the hot and humid climate of
south Texas. The commissioning involved the
installation of a VFD (Variable Frequency Drive) on
a chilled water pump, improved ...
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 ...
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 ...
