Air Handling Unit Supply Air Temperature Optimization During Economizer Cycles
(Texas A&M University (http://www.tamu.edu)Energy Systems Laboratory (http://esl.tamu.edu), 2007)
Most air handling units (AHUs) in commercial buildings have an air economizer cycle for free cooling under certain outside air conditions. During the economizer cycle, the outside air and return air dampers are modulated ...
Achieving High Chilled Water Delta T Without Blending Station
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
Typically a blending station is designed to ensure that its user is able to avoid low chilled water return temperature in the district cooling system. When the chilled water return temperature drops to a low limit, building ...
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 ...
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 ...
Development of Power-head based Fan Airflow Station
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2005)
Decoupled Modeling of Chilled Water Cooling Coils Using a Finite Element Method
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2005)
Supply Fan Control for Constant Air Volume Air Handling Units
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
Since terminal boxes do not have a modulation damper in constant volume (CV) air handling unit (AHU) systems, zone reheat coils have to be modulated to maintain the space temperature with constant supply airflow. This ...
Optimal Terminal Box Control for Single Duct Air-Handling Units
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2006)
Terminal boxes maintain room temperature by modulating supply air temperature and airflow in building HVAC systems. Terminal boxes with conventional control sequences often supply inadequate airflow to a conditioned space, ...
Optimal Outside Air Control for Air Handling Units with Humidity Control
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2006)
Most air handling units (AHUs) in commercial buildings have the (air) economizer cycle to use outside air for free cooling under certain outside air conditions. Ideally the economizer cycle is enabled if outside air enthalpy ...
