A Novel Procedure to Determine Optimal Air Static Pressure Set-points and Reset Schedules in VAV Air Handling Units
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
Air static pressure set-point or schedule for VAV
AHLJ systems is one of the most crucial
operational parameters for satisfy lug the building
load, maintaining the room comfort level and
saving energy costs. This paper ...
An On-line Self-tuning Algorithm of PI Controller for the Heating and Cooling Coil in Buildings
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
An on-line self-tuning algorithm of PI controller
for the heating and cooling coil in buildings is
described in the paper. The algorithm evaluates
the controller performance by the integral
square error (ISE) of the coil ...
Impacts of Optimized Cold & Hot Deck Reset Schedules on Dual Duct VAV Systems - Application and Results
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
In the theory and modeling part, the
principles of VAV box optimization are
investigated. The simulations show that
optimizing cold and hot deck reset schedules can
significantly reduce the amount of energy
consumption.
During ...
Integrated Commissioning for a Large Medical Facility
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
The energy costs of heating, ventilating and
air conditioning usually represents a large
portion of the utility bills for a medical facility.
One large, modem medical center located in the
hot and humid region of southern ...
Optimize the Supply Air Temperature Reset Schedule for a Single-Duct VAV System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
The supply air temperature for a single-duct
variable air volume (VAV) system is usually set as a
constant. To minimize the simultaneous cooling and
heating, this supply temperature is often reset based
on either return ...
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 ...
Continuous Commissioning of a Central Chilled Water & Hot Water System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
A central chilled water / hot water system
provides cooling / heating energy from central utility
plants to multiple customers (buildings) through
campus distribution loops. To effectively transport
the chilled water and ...
Development of a Procedure for the Predictive Control Strategy of a Chilled Water Storage System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
Thermal energy storage systems store the
thermal energy produced by the chiller plant in
periods of off-peak electrical demand or when
cheaper electricity is available. The stored thermal
energy is then withdrawn from the ...
Optimization Measures for Sporting and Special Event Facilities: Design and Operation
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
Reducing unnecessary building energy costs
is becoming more of a priority. Rising fuel
prices and a global emphasis on energy
efficiency are key contributing factors. This
push towards energy efficiency certainly applies
to ...
Optimization Control Strategies for HVAC Terminal Boxes
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2000)
The HVAC terminal boxes are one of the
major building HVAC components. They
directly impact the building room comfort
conditions and the energy costs. How to operate
the box in a highly energy efficient way and
maintain ...
