Open publisher page 0 citations

Abstract

Universiti Teknologi PETRONAS (UTP) uses district cooling (DC) system for air-conditioning purpose. The UTP GDC plant produces chilled water. Chilled water is produced by two different types of chillers namely the Electric Chiller (EC) and Steam Absorption Chiller (SAC). This study investigated the performance of both EC and SAC by evaluating Coefficient of Performance method (COP) under theoretical and actual operating conditions. Microsoft Excel spreadsheet software was used to evaluate the COP. Historical data from UTP GDC from January 2016 to March 2016 were used for analysis. Evaluated COP for the electric chiller varies from 3.12 to 7.11 while the evaluated COP for steam absorption chiller varies from 1.07 to 1.31.
