The ventilation system of cargo hold for pure car truck carrier(PCTC)can be divided into three design schemes according to different exhaust methods during sea going:complete natural exhaust,partial natural exhaust and complete mechani-cal exhaust.Taking one floor of PCTC cargo area as an example,the comparative analysis showed that the energy consumption of completely natural exhaust is the smallest with good ventilation flow field,but the air duct occupies the largest space;the com-plete mechanical exhaust takes up the smallest space with the best ventilation flow field,but the energy consumption is the lar-gest;the ventilation flow field of partial natural exhaust is relatively poor,the energy consumption and the space occupied by the duct are between the other two schemes.It was recommended that the upper cargo hold adopt complete natural exhaust,the mid-dle cargo hold adopts partial natural exhaust and the lower cargo hold adopts complete mechanical exhaust.
