船舶舱室通风方式直接决定各区域内部的空气质量。实验研究和传统的计算流体力学算法耗时较长，为此将多区域网络通风模型引入到舱室通风控制策略的影响研究中。以典型舱室和通风系统结构为基础，采用多区域污染物传播算法，获得不同通风控制策略下的各区域污染物浓度变化规律。结果表明，基于浓度反馈控制的通风策略与基于时间或新风量控制的通风策略相比，能够降低10%的空气质量超标风险，在空气质量保障和节能运行上具有显著优势。
The ventilation mode of ship cabin determines the air quality in each area. Experimental research and traditional computational fluid dynamics algorithms take a long time. Therefore, the multi area network ventilation(AFN) model is introduced into the study of the influence of ventilation control strategy. Based on the typical cabin and ventilation system structure. Based on the typical cabin and ventilation system structure, the AFN algorithm is adopted to obtain the variation law of pollutant concentration in each region under different ventilation control strategies. The results show that the ventilation strategy based on concentration feedback control can reduce the risk of air quality exceeding the standard by 10% compared with the ventilation strategy based on time or fresh air volume control, and has significant advantages in air quality assurance and energy-saving operation.
