客滚船住舱气流组织的数值模拟研究

基于长江航线的工况对客滚船提出了人员住舱的空调系统方案。在此基础上,基于Airpak软件研究了客滚船住舱气流特性。其次,基于气流组织分布的评价指标,对夏季和冬季工况下客滚船舱室舒适性进行评价分析。最后,通过能量利用系数值,给出经济性好的空调系统方案。研究结果表明:①辐射空调系统能够在全工况下营造舒适性更高的室内热环境,相比于常规空调系统,其表征热舒适性的PMV-PPD(predicted mean vote-predicted percentage of dissatisfied)值完全满足ISO7730规范的要求,且热环境舒适度均匀性更高;②辐射空调系统送风得到了充分的利用,经济性好。

Numerical Simulation Study on Cabin Airflow Distribution of Ro-ro Passenger Ship

Based on the working condition of the changjiang river route, the scheme of the air conditioning system for the passenger cabin is proposed.On this basis,Airpak software is used to study the cabin airflow characteristics of living rooms on the Ropax ships.Secondly, based on the evaluation index of air distribution, the comfort of passenger roller cabin is evaluated and analyzed in summer and winter.Finally, through the value of energy utilization coefficient,the scheme of economical air-conditioning system is given.The results of research shows that: (1)Radiant air conditioning system can create indoor thermal environment with higher comfort under all working conditions. Compared with conventional air conditioning system, the PMV-PPD (Thermal comfort evaluation index) value of its thermal comfort fully meets the requirements of ISO7730 specification, and the comfort uniformity of thermal environment is higher. (2)The air supply from the radiant air conditioning system is fully utilized,and it has good economical effect.
