Abstract: Using numerical simulation method, the air side heat exchange performance of the direct air cooled condenser was analyzed. The operation conditions of the air cooled condenser under different wind velocity and different wind direction were simulated. The main mechanism of the influence of wind velocity and wind direction on the air flow of each unit of the air cooled condenser was expounded. The measures to improve wind environment were put forward, and the effectiveness of the measures was proved by the numerical simulation results.

Key words: air cooled condenser, wind environment, numerical simulation, impact analysis
