摘要
大型舰船舱室多采用半封闭或全封闭式设计,需要通过机械通风系统对舱室进行通风换气。本文根据大型舰船舱室密闭环境特点,结合2艘典型舰船舱室通风系统换气效果试验,建立舱室通风换气的数学模型,计算对比了通风换气期间舱室污染物的浓度变化情况,并提出有效通风量作为性能参数来评估舱室通风换气系统效能,直观地反映舰船舱室通风换气效果。该研究可为舰船舱室通风系统的设计及优化提供一定的指导。
Ventilation system for enclosed space chambers of large vessels are designed as initiative mechanical ventilation system.Based on the characteristics of the enclosed space chambers and the ventilation test results of two typical vessels,this paper builds the ventilation model for the enclosed space chambers and compares the CO_2 concentration variation during the ventilation.The effective ventilating rate is proposed to evaluate the efficiency of the vessel chamber ventilation system.The results show that the calculated results of ventilation model agree well with the tested results.Moreover,the effective ventilating rate proposed in this paper could intuitively indicate the efficiency of the vessel chamber ventilation system.This study is supposed to offer some guidance for the design and optimization of the vessel chamber ventilation system.
