When diesel generator room adopts clean ventilation, Please calculate the intake air volume and the exhaust air volume as follows:
- When the generator room is air cooled, the intake air volume is calculated by eliminating the residual heat in the room;
- When the diesel generator room is water cooled, It is calculated according to the ventilation required that eliminate harmful gases in the diesel generator room. The allowable content of harmful gas is taken: CO 30 mg/m3, acrolein 0.3 mg/m3. Or calculate the inlet air volume by greater than or equal to 20m3/(kW·h).
- The exhaust air volume is the intake air volume minus the combustion air volume. The engine combustion air volume can be calculated based on the empirical data of the engine rated power: 7m3/(kW·h). When clean and ventilation, the combustion air can be directly taken from the generator room. For protection, outdoor air should be introduced from the air inlet or exhaust duct of the engine room for combustion, but the resistance of the suction system should not exceed 1kPa.
