A gas turbine operated at the University Technology PETRONAS Gas Turbine District Cooling Plant produces an average of 3258 kWh with 30% of estimated gas turbine efficiency. A previous study done by the writer has shown of 20% increase in the efficiency of a gas turbine with the implementation of the turbine inlet air cooling. The sizing of the Heat Exchanger needed to be determined as the existing air inlet is only a 30 ft2 flange attached directly to the compressor of the gas turbine. This studies conclude that a 320 ft2 heat exchanger is needed in order to reduce the air inlet fluctuations (a range of 23–34 °C) to 15 °C. By placing the heat exchanger in the gas turbine, a significant Pa pressure loss of approximately 187.55 was experienced.
