Review
Period Four discussed the issues related to chiller-plant control, including chiller
sequencing, failure recovery, contingency planning, system tuning, and system-
level optimization.
Remember that you cannot “control your way out of” a poor system design.
Although the control system can attempt to minimize the impact of a poor
design, it cannot eliminate the cause of the poor design.
Second, even a properly installed system with good components requires
system-level control to make those components work together effectively.
Third, even if the components are working together, the system, not the
individual components, needs to be optimized. Remember: the meter is on
the building.
Finally, a very important issue that is related to chiller-plant control is the issue
of interfacing with the person who is operating the system. Simplicity is
important, and it gives the system a much better chance of working without
intervention by the operator.
