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 ...
Variable Speed Drive Volumetric Tracking (VSDVT) for Airflow Control in Variable Air Volume (VAV) Systems
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
An airflow control method has been developed
for variable air volume (VAV) systems. This airflow
control method is named VSD volumetric tracking
(VSDVT) since both the supply and return airflows
are determined using signals ...
Single-Duct Constant Air Volume System Supply Air Temperature Reset: Using Return Air Temperature or Outside Air Temperature?
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
The supply air temperature set point for a singleduct
constant air volume air handling unit (AHU)
system is often reset based on either return air
temperature or outside air temperature in order to
reduce simultaneous ...
