Steam Plant Chiller

Description
The goal of this project is divided into two parts. Part one is to specify, order, and install various flow and pressure sensors to the existing chiller system. Additionally, a math model is to be developed of the current system with the sensors installed. Part two will consist of validating the math model, testing the sensors, and performing data acquisition on the chiller. The data will then be used within the math model in order to find areas for improvement and money saving opportunities such as implementing a control system strategy.

Background
http://www.uidaho.edu/facilities/energy/statistics/chilledwatersystem This link gives a brief description of the ongoing operations happening throughout all of the chilling stations on campus.

The South Campus Chiller Plant became functional in the year 2010. It consisted of two centrifugal chillers, two evaporative cooling towers, one thermal energy storage tank, and a reverse osmosis unit. Today it consists of the same components and has room for two more chilling units.

=Current System Model= The Current System Model is broken up into 6 stages.
 * 2 Chillers
 * 8 Compressors
 * 2 Cooling Towers
 * 2 Pumps
 * 2 Condensate Pumps
 * Thermal Energy Storage (TES) Tank

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

The program Engineering Equation Solver (EES) is used to model the current chiller system, and estimate the efficiency using inputs of chiller generated and fuel usage.

Problem Definition
After investigating the operation of the south campus chiller plant (SCCP), opportunities for improvement were discovered.
