Improving Control of a Dual-Duct Single-Fan Variable Air Volume Systems
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2003)
This paper discusses improved control strategies
for dual-duct single-fan variable air volume (VAV)
systems. Common control strategy for supply air
volume modulation is evaluated, and an improved air
volume control strategy ...
Chiller Start/Stop Optimization for a Campus-wide Chilled Water System with a Thermal Storage Tank Under a Four-Period Electricity Rate Schedule
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
The existence of a 1.4-million-gallon
chilled water thermal storage tank greatly
increases the operational flexibility of a campuswide
chilled water system under a four-part
electricity rate structure. While significant
...
A Method for Simulating Heat Recovery Systems Using AirModel in Implementations of the ASHRAE Simplified Energy Analysis Procedure
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2005)
Exploring Maximum Humidity Control and Energy Conservation Opportunities with Single Duct Single Zone Air-Handling Units
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2006)
Humidity control for single-duct single-zone (SDSZ) constant volume air handling units is known to be a challenge. The operation of these systems is governed by space temperature only. Under mild weather conditions, discharge ...
Airside Economizer- Comparing Different Control Strategies and Common Misconceptions
(Energy Systems Laboratory (http://esl.tamu.edu), 2008-10)
Air-side economizer is broadly adopted in building HVAC design and operations. When the system is properly designed and the control sequence is properly implemented, air-side economizer provides significant energy savings. ...
Single-Duct Constant Air Volume System Supply Air Temperature Reset: Using Return Air Temperature or Outside Air Temperature?
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2002)
The supply air temperature set point for a singleduct
constant air volume air handling unit (AHU)
system is often reset based on either return air
temperature or outside air temperature in order to
reduce simultaneous ...
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 ...
Airside Economizer – Comparing Different Control Strategies and Common Misconceptions
(Energy Systems Laboratory, 2008-12)
Air-side economizer is broadly adopted in building HVAC design and operations. When the system is properly designed and the control sequence is properly implemented, air-side economizer provides significant energy savings. ...
Lessons and Measures Learned from Continuous Commissioning(SM) of Central Chilled/Hot Water Systems
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2001)
As it has been proved repeatedly that
commissioning is very necessary for new construction
and renovation/retrofit projects, we found continuous
commissioningSM (CC) is an effective and efficient
way to manage and optimize ...
