Abstract
A pull-down control process for a chiller system is provided. The pull-down control process can override the capacity control process for the chiller system to pull-down the leaving chilled liquid temperature faster than the capacity control process. The pull-down control process can maintain pre-rotation vanes in a fully open position to pull-down the leaving chilled liquid temperature as quickly as possible to a predetermined setpoint.
