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 ...
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 ...
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 ...
Impacts of Static Pressure Reset on VAV System Air Leakage, Fan Power and Thermal Energy - Part 2: Case Demonstration for a Typical Climate System
(Energy Systems Laboratory (http://esl.tamu.edu)Texas A&M University (http://www.tamu.edu), 2007)
In Part 1 of this paper, the theoretical models, integrating the fan airflow, fan head, air leakage factors, are developed to analyze the impacts of the static pressure reset on both pressure dependent and pressure independent ...
