Abstract： Based on the 2 200 t crane ship designed and built in our company， the amount of air needed for the whole engine room is analyzed by calculating the amount of air needed for heat dissipation and combustion in the engine room. At the same time， according to the engine room air duct layout， considering the farthest branch pipe air supply situation， the air supply pressure loss of the end and funnel exhaust loss are analyzed， the fan pressure loss is calculated， so as to select the engine room fan required air volume and static pressure.

Key words： Fan; Air change ratio; Heat dissipation; Combustion; Pressure loss
