South Campus Chiller

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

Specifications

 * 1.0E6 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
We are looking into adding weather prediction as a means of reducing cost of operation at the South Campus Chiller Plant.

EES Verification
