South Campus Chiller

The south chiller produces chilled water for cooling of the entire UI campus. The SCCP uses cooling towers to take the heat out of the water being sent out to campus. The cooling towers work by misting the warm water down through air. The amount of heat being pulled out of the water being misted down is affected by ambient temperature.

Problem Definition
Data collected from the south chiller's current operating condition suggest areas of inefficiencies, leading to unnecessary operating costs.

Project Goals:

 * Specify, order, and install flow, pressure, and temperature sensors
 * Develop a working math model of the existing chiller system
 * Test math model against current operating conditions
 * Develop a control system solution strategy
 * Quick reference for plant efficiency's
 * Excel calculator for efficiency calculation
