In recent years, direct air cooling units have developed rapidly in India, but in the actual operation, the
back-pressure often deviate from the optimal back-pressure, which affect the economy of the unit. In order to figure out
the optimum back-pressure multi-objective optimization process should to be carried out using the current parameters of
air cooled condenser(ACC) and reducing them to optimum using mathematical modelling and creating algorithms in
software to get results. The optimization objective functions will be the turbine back-pressure, and the optimization
parameters should be face velocity, windward area of air-cooling condenser and number of transfer units (NTU) or any
pairs of these parameters based on the requirements. This review mainly focused on various work carried out in
optimization in ACC and the Turbine back pressure optimization.
