Show full item recordAbstract
This paper describes a success story on energy management
of the chiller plant at Georgia Tech. A multilevel
control and optimization method is implemented by
using distributed control systems. Substantial energy
savings, reduced manpower costs, and improved plant
operation is realized.
The main features of the system is its ability to control,
optimize, and coordinate at three respective levels
while meeting the operational requirements of plant
chillers. The chiller energy management is an integrated
part of total energy management system including the
boilers. A uniform display is used for boilers, chillers,
compressors, etc. Specific control logics are presented.
Graphic displays of the equipment along with trends and
bar graphs are shown on CRT by single or a few operator-friendly
keystrokes. The energy savings and operational
improvements are discussed along with the
distributed control equipment. The advantages of
distributed control system as evidenced in this particular
application are described.
