Post-Retrocommissioning HVAC Operations Monitoring Using Enterprise-Wide energy Management System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
Since 2004, the County of Los Angeles have retrocommissioned over 4 million square feet and additional RCx work is underway. The scope of the HVAC retrocommissioning (RCs) involved systematic investigation of mechanical, ...
Achieving High Chilled Water Delta T Without Blending Station
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
Typically a blending station is designed to ensure that its user is able to avoid low chilled water return temperature in the district cooling system. When the chilled water return temperature drops to a low limit, building ...
Economizer Control Using Mixed Air Enthalpy
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
Enthalpy economizer can theoretically save more energy than temperature based economizer. However, the requirement of outdoor air humidity measurement in the traditional enthalpy economizer control made it impossible. A ...
