North Campus Chiller

The University of Idaho North Campus Chiller Plant is used to create and disperse chilled water throughout the university of Idaho Facilities. The intent of this project is to develop and validate a math model of the NCCP, take inventory of the system instrumentation and see what addition sensors are needed, and also use the collected data in the math model to see how the system will perform in various operating conditions.

Background
The North Campus Chiller Plant (NCCP) is a plant that removes heat from water via absorption refrigeration cycle. The chilled water is then circulated through heat exchangers to cool university of Idaho's equipment as required. The NCCP 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
The University of Idaho campus utilizes the North Campus Chiller Plant to supply cold water which is sent by piping into the various buildings to air handling units. Our group plans to find ways to make the chiller system more efficient by developing a model and testing it out with data collected from sensors we will install.

Data Analysis
Throughout the system, the data collected from the sensors and ATS data acquisition devices was put into an excel file. Data from each instrument was put into individual files. Then we compiled the data into one excel file and implemented it into our EES math model. With the values received from our math model we then created plots to show the performance of the chiller under various operating conditions.
