摘要
为研究辐射供冷末端布置对邮轮舱室热环境的影响,文章采用气流组织分析软件Airpak对不同供冷工况下舱室热环境进行模拟,分析对比各工况下舱室的温度分布、速度分布,并利用评价指标PPD-PMV值和平均空气龄对人员主要活动区域的热舒适性进行研究。结果表明,相比于辐射垂直墙壁系统,顶板供冷在X轴方向的温度分布更加均匀,人员无明显吹风感,舱室内人员的感觉最舒适。
In order to study the influence of radiant cooling terminal arrangement on the thermal environment of cruise cabins,the article uses airflow organization analysis software Airpak to simulate the cabin thermal environment under different cooling conditions,and analyze and compare the temperature distribution and speed distribution of the cabin under various conditions.,And use the evaluation index PPD-PMV value and average air age to study the thermal comfort of the main activity area of personnel.The results show that,compared with the radiation vertical wall system,the temperature distribution of the ceiling cooling in the X-axis direction is more uniform,the personnel have no obvious blowing feeling,and the personnel in the cabin feel the most comfortable.
