Abstract：Based on equipment condition and by means of site survey,the reserved area of air inlet / outlet of diesel generator room is calculated. Analysis shows that the reason for insufficient power of diesel generator unit is that the effective ventilation area of the shutters for noise reduction construction is insufficient. And relevant rectification measures are proposed.
