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 ...
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 ...
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 ...
Optimizing HVAC Control to Improve Building Comfort and Energy Performance
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2003)
This paper demonstrates the benefits of optimal
control in well-designed and operated buildings using
a case study. The case study building was built in
2001. The HVAC and control systems have been
installed with ...
An Integrated Air Handling Unit System for Large Commercial Buildings
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2001)
This paper presents an integrated air handling
unit system (OAHU) for large commercial buildings.
The system introduces outside air into the interior
section and circulates the return air to the exterior
section. Detailed ...
