South Campus Chiller

The south chiller produces chilled water for cooling of the entire UI campus.

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 calc

Specifications

 * 1,000,000 gal storage tank
 * Trending data for 50 thermodynamic states
 * HFC-134A Refrigerant
 * 500ton capacity(x2)
 * Evapco evaporators(x2)
 * 40Hp Armstrong Pumps(x2)
 * Kiltech chiller(x2)
 * ABB Variable Frequency Drive(x6)

Control System Ideas

 * Weather prediction
