柴油發(fā)電機房采用清潔式通風時，應按下列規(guī)定計算進、排風量：

When diesel generator room adopts clean ventilation,Calculate the intake air volume and the exhaust air volume as follows:

1.當柴油發(fā)電機房采用空氣冷卻時，按消除柴油發(fā)電機房內余熱計算進風量；

1. When the diesel generator room adopts air cooling, the intake air volume is calculated by eliminating the residual heat in the diesel generator room;

2.當柴油發(fā)電機房采用水冷卻時，按排除柴油發(fā)電機房內有害氣體所需的通風量經(jīng)計算確定。有害氣體的容許含量取：CO為30mg／m3，丙烯醛為0.3mg／m3，或按大于等于20m3／(kW·h)計算進風量；

2.When the diesel generator room is water-cooled, the permissible amount of harmful gases determined by removing the amount of ventilation required for harmful gases in the diesel generator room is: CO is 30 mg/m3, and acrolein is 0.3 mg/m3. Or calculate the amount of air intake greater than or equal to 20 cubic meters/(kilowatt-h);


3.排風量取進風量減去燃燒空氣量。

柴油機燃燒空氣量，可根據(jù)柴油機額定功率取經(jīng)驗數(shù)據(jù)計算：7m3／(kW·h)。清潔通風時，柴油機所需的燃燒空氣直接取用發(fā)電機房室內的空氣；隔絕防護時，應從機房的進風或排風管引入室外空氣燃燒，但吸氣系統(tǒng)的阻力不宜超過1kPa。

3.Exhaust volume is equal to wind intake minus combustion wind quantity.

The amount of diesel engine combustion air can be calculated based on the diesel engine rated power and empirical data: 7m3/(kW·h).For clean ventilation, the combustion air required by the diesel engine directly uses the air in the generator room. In the case of isolation and protection, outdoor air shall be introduced from the air inlet pipe or exhaust pipe of the engine room, but the resistance of the air intake system should not exceed 1 kPa.
