The most common Cooling Tower Control System uses a fixed temperature setting for the condenser water supplied back to the chillers. For convenience, let’s label this temperature:

TO = Tower Outlet temperature

To control this value, most controls technicians would program a control loop (PID or similar) to vary the overall Cooling Tower Fan usage in order to maintain this temperature. In most large buildings, multiple Cooling Tower Fans are available for this purpose. Continue reading Cooling Tower Control Based on “Approach”
