    • Achieving High Chilled Water Delta T Without Blending Station 
      Wang, Z.; Wang, G.; Xu, K.; Yu, Y.; Liu, M. (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 ...
    • Air Handling Unit Supply Air Temperature Optimization During Economizer Cycles 
      Xu, K.; Liu, M.; Wang, G.; Wang, Z. (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 ...
    • Building Aautomation system embedded air-handling unit performance degradation detector 
      Song, L.; Wang, G. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2014)
    • CC Retrofits and Optimal Controls for Hot Water Systems 
      Wu, L.; Liu, M.; Wang, G. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2007)
      Boilers account for about 42% of space heating energy consumption in commercial and multifamily buildings in the U.S. Boilers are typically designed to be oversized, with redundant safety factors and without consideration ...
    • Decoupled Modeling of Chilled Water Cooling Coils Using a Finite Element Method 
      Wang, G.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2005)
    • Development of Power-head based Fan Airflow Station 
      Wang, G.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2005)
    • Energy Efficient Single Stack Exhaust Fan Systems (E3S3F) 
      Wang, G.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2001)
      This paper first investigates the fan energy performance of a constant air volume exhaust system. Two single stack energy efficient exhaust fan systems (E3S3F) are presented. The E3S3F-I has the static pressure sensor ...
    • Optimal Outside Air Control for Air Handling Units with Humidity Control 
      Wang, G.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      Most air handling units (AHUs) in commercial buildings have the (air) economizer cycle to use outside air for free cooling under certain outside air conditions. Ideally the economizer cycle is enabled if outside air enthalpy ...
    • Optimal Terminal Box Control for Single Duct Air-Handling Units 
      Cho, Y.; Vondal, J.; Wang, G.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      Terminal boxes maintain room temperature by modulating supply air temperature and airflow in building HVAC systems. Terminal boxes with conventional control sequences often supply inadequate airflow to a conditioned space, ...
    • Supply Fan Control for Constant Air Volume Air Handling Units 
      Cho, Y.; Wang, G.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2007)
      Since terminal boxes do not have a modulation damper in constant volume (CV) air handling unit (AHU) systems, zone reheat coils have to be modulated to maintain the space temperature with constant supply airflow. This ...
    • Test and Reconstruction of Air Conditioning System in a Hotel Lobby 
      Wang, G.; Hu, Y.; Hu, S.; Chen, Q. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      Two air conditioning systems are equipped in a hotel lobby. It is found from the field test that the actual air rate is 40% and 16% of the nominal value, respectively, of the two systems, which is far lower than the design ...
    • Theoretical Study of a Novel Control Method of VAV Air-conditioning System Based on MATLAB 
      Shi, Z.; Hu, S.; Wang, G.; Li, A. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      The main purpose of this study is to put forward a novel nonlinear feedback control strategy on controlling indoor air temperature by variable air volume. A dynamic model of a typical room for a VAV air-conditioning system ...
