Performance Analysis of Absorption and Electric Chillers At Gas District Cooling
The paper presents a study on chillers performance at a gas district plant during peak and off peak periods for campus cooling. The plant is designed to produce electrical power and chilled water from a Co-generation System and supply the chilled water and electricity to the campus. Since the campus...

| Summary: | The paper presents a study on chillers performance at a gas district plant during peak and off peak periods for campus cooling. The plant is designed to produce electrical power and chilled water from a Co-generation System and supply the chilled water and electricity to the campus. Since the campus chilled water supply depends solely from the chillers operations, the status of the performance of the chillers need to be continuously evaluated. Using coefficient of performance (COP), the performance both the absorption and electric chillers was analyzed. This COP analysis is the follow up from the earlier evaluation which was done in the year 2001. Results of the analysis indicate that there is a decrease in performance for the year 2011 in comparison to the year 2005. In terms of chilled water production the performance decreases approximately by 5 per cent. While in terms of coefficient of performance there is a decrease by 43 percent from the year 2005 for the Absorption Chiller and 32 percent increase for Electric the chillers. |
