Various duty calculations for direct dry cooling system are studied. Mathematical model of variety - duty calculation for ACC （air - cooled condenser） is presented. Take example for 600 MW power plant, the influence of heat loads, ambient temperature and wind velocity on condenser pressure are obtained. Variety - duty characteristics of ACC are analyzed, which provides strong theoretical basis for improving the security, the economical efficiency and the performance of direct dry cooling units.
