船舶人员聚集区空调送风模式的比较分析

Comparison and analysis of air supply mode in ship's public space

对船舶人员聚集区空调送风的方式进行了比较和分析.根据实船设计的案例(南京长江油运公司7万吨级载重量原油/成品油船的会议室空调送风),通过采用计算流体动力学CFD(Computational Fluid Dynamics)的方法,对布风器送风和散流器两种送风方式下的会议室的温度和速度分布进行计算机模拟.通过对温度、风速、空气年龄和舒适度各项指标的比较分析,对该类处所的空调送风模式提出合理的建议.

This paper compares and analyzes the air supply mode of ship＇s public space. According to actual design example （the meeting room air supply designing of 70,000DWT crude/product oil tanker）, it uses CFD method to simulate temperature and velocity distribution in the meeting room under the two air supply modes such as grid air condition and air diffuser. According to the analysis and comparison of temperature, velocity air age and thermal comfort index, it gives reasonable proposals of air supply mode in public space.
