The Measured Energy Impact of Infiltration Under Dynamic Conditions
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
Energy consumption due to air infiltration is customarily assumed to equal the mass flow rate times the specific enthalpy difference between the inside and outside air. Anderlind showed theoretically that this represents ...
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 ...
Reduce Building Energy Consumption by Improving the Supply Air Temperature Schedule and Recommissioning the Terminal Boxes, Submitted to the Energy Management and Operations Division at the M.D. Anderson Cancer Center
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1995)
At the request of the Energy Management and Operations Department at M.D. Anderson Cancer Center, the Energy Systems Laboratory of Texas A&M University performed a study of optimizing the HVAC operation at its Basic Research ...
Use of EMCS Recorded Data to Identify Potential Savings Due to Improved HVAC Operations & Maintenance (O&M)
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 1996)
In most chiller and boiler central plants, the
energy management and control systems (EMCS)
monitor and record key operation parameters and
energy production continuously. A method was
developed to identify potential O&M ...
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 ...
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 ...
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 ...
Performance Analysis of Dual-Fan, Dual-Duct Constant Volume Air-Handling Units
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2001)
Dual-fan, dual-duct air-handling units introduce
outside air directly into the cooling duct and use two
variable speed devices to independently maintain the
static pressure of the hot and the cold air ducts.
Analytical ...
Impacts of Static Pressure Reset on VAV System Air Leakage, Fan Power and Thermal Energy - Part I: Theoretical Model and Simulation
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
As for a variable air volume (VAV) system, the air duct static pressure is a typical control variable maintained by modulating supply fan speed. The static pressure equals to the summation of the duct pressure loss downstream ...
