船舶住舱辐射空调送回风方式格序优选研究

Air supply and return modes optimization of radiation air conditioning in ship cabin using lattice order decision-making approach

  • 摘要:
    目的 旨在研究住舱内部环境对人员生活舒适度和工作效率的影响,提高和改善船舶空调系统的热舒适性。
    方法 对典型船舶单人住舱的异侧上送下回、同侧上送下回、异侧下送上回以及同侧下送上回4种送回风方式,使用Airpak软件对住舱内的温度场、湿度、PMV-PPD和空气龄等参数进行仿真模拟分析。
    结果 结果表明:采用异侧上送下回送风的室温可恒定于24℃,湿度保持在50%左右且湿度场分布更为均匀,PMV分布更均匀且其值趋于0,空气龄PPD在舱内的分布更为均匀且数值很小。
    结论 运用格序理论优选原理,在船舶单人住舱中,异侧上送下回的送回风方式为优选方案。

     

    Abstract:
    Objective The study in this paper aims to investigate the impacts of cabin atmosphere quality on the comfort and the work efficiency of crew member aboard the ship, thereby the degree of thermal comfort of ship air conditioning system can be improved.
    Method Airpak software is used to simulate and analyze the temperature, relative humidity, PMV-PPD and air age in the four air return modes of a typical single-occupant cabin of a ship, namely ‘different side up and down cycles’, ‘same side up and down cycles’, ‘different side down and up cycles’, and ‘same side down and up cycles’.
    Results The simulation results show that the temperature in the cabin can be kept constant at 24℃, humidity can be maintained at about 50% and the humidity field distribution can be more uniform, while PMV (predicted mean vote) distribution is more uniform with its value tending to zero, and the air age PPD (predicted percentage of dissatisfied) distribution is more uniform with a very low value in the cabin.
    Conclusion Using the optimization principle of lattice order theory, the air return mode of ‘different side up and down cycles’ is the optimal scheme for a single-occupant cabin of a ship.
