Assignment Questions:

Question 1

You are required to conduct an energy audit on a commercial building water-cooled chiller plant. The building maintenance team submitted the raw data reading (excel format) of the chiller plant as provided in Appendix A. Prior to conducting the energy audit, you may use the given raw data to generate the charts and tables to understand the chiller plant’s existing condition.

Provide the following charts and tables for interpretation.

• Cooling load Profiles
• Heat Balance Profile
• Chiller Plant Efficiency Profile
• Frequency of Cooling Load Occurrences (Bin interval of 20)
• Chiller Plant Efficiency vs Cooling Load Profile
• Chiller Power versus time
• Chilled water temperature differences versus time
• Condenser water temperature differences versus time
• Tabulate the summary of the chilled water plant performance
• Tabulate the heat balance summary

Question 2

Discuss and analyze each individual plots and tables that you have generated from Question 1.
