Abstract: In the direct air cooling system, the key technology of air supply system is the optimal selection and design of axial fan. It is of great importance on the optimal design and economical operation of air cooling system. The static pressure of the axial fan depends on the flow resistance of the air cooled condenser (ACC).The causes of pressure losses when air passing through each part of A-shape air cooled condenser were analyzed. The resistance coefficient at different part of the bundles was determined. It offers good help for the optimal design of direct air cooling system.
