Impacts of Optimized Cold & Hot Deck Reset Schedules on Dual Duct VAV Systems - Theory and Model Simulation
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
Optimal hot and cold deck reset schedules
can decrease simultaneous heating and cooling
in VAV AHUs comparing with constant cold
deck temperature operation. In this paper,
optimization models are developed. The energy
impacts ...
Reducing Pump Power Consumption by 40% (1000 KW) Through Improved Pump Management in a Central Plant
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
Chilled water system data collection and field
measurements performed at the Central Utility Plant
of Texas A&M University revealed that 30 - 50 % of
the primary pump head is consumed by manual and
automatic valves being ...
Rehabilitating A Thermal Storage System Through Commissioning
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
A thermal storage system was installed in a
37,000 ft2 hospital in April 1992. The chiller
had to be operated every summer during peak
demand periods until the authors rehabilitated
system through building commissioning ...
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 ...
Signatures of Heating and Cooling Energy Consumption for Typical AHUs
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
An analysis is performed to investigate the
signatures of different parameters on the heating
and cooling energy consumption of typical air
handling units (AHUs). The results are presented
in graphic format. HVAC simulation ...
Impacts of Water Loop Management on Simultaneous Heating and Cooling in Coupled Control Air Handling Units
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1998)
The impacts of the water loop management
on the heating and cooling energy consumption
are investigated by using model simulation. The
simulation results show that the total thermal
energy consumption can be increased by ...
