摘　　要：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。Based on the working condition of the Changjiang(Yangtze)River route,a scheme of air conditioning system in passenger cabin of a ro-ro passenger ship was proposed.First,the cabin airflow characteristics of living rooms on the ships was analyzed with Airpak software.Second,the comfort of passenger roller cabin was evaluated and analyzed in summer and winter based on the evaluation index of air distribution.Finally,the scheme of economical air-conditioning system was given according to the value of energy utilization coefficient.Results show that the radiant air conditioning system could create an indoor thermal environment in better comfort under all working conditions.Compared with conventional air conditioning system,the predicted mean vote vs predicted percentage of dissatisfied(PMV-PPD)value of its thermal comfort could meet the requirements of ISO7730 specification entirely,and the comfort uniformity of thermal environment was higher.The air supply from the radiant air conditioning system was fully utilized in a good economic effect.
