Analysis of the Efficiency of Engine Inlet Air Chilling Unit with Cooling Towers

The processes of cooling air at the inlet of energy installations by exhaust heat conversion chillers with heat removal from them by cooling towers of the circulating cooling system are studied on the example of a gas turbine. Two-stage air cooling is considered using combined type exhaust heat conversion chillers, which utilizes the exhaust gas heat of a gas turbine and which includes absorption lithium-bromide and refrigerant ejector chillers as stages to convert waste heat into cold. The data on current heat loads on exhaust heat conversion chillers and cooling towers in accordance with climatic conditions of operation with the different distribution of heat loads on the cooling towers according to their number was obtained on the base of the results of modeling the operation of the gas turbine cooling complex. It was shown the possibility to increase the fuel saving due to turbine inlet air cooling through decreasing the number of cooling towers and electricity consumption for driving the fans of cooling towers.
