变风量空调系统末端装置型式多样,能否在舰船上使用并达到相应效果是业内人士关心的问题。因此对舰船空调末端装置进行分析,采用k-e湍流模型对舱室空气流动进行数值模拟,并运用Fluent软件进行模拟计算,得出了船员舱室的温度场和速度场的分布。由舱室温度分布均匀和无明显送风下坠和射流冷风感,得出诱导型变风量末端和带热交换器动力型末端送风方案都能满足舱室舒适性要求,为变风量末端装置在舰船上更好地使用提供了理论依据。
變風量空調繫統末耑裝置型式多樣,能否在艦船上使用併達到相應效果是業內人士關心的問題。因此對艦船空調末耑裝置進行分析,採用k-e湍流模型對艙室空氣流動進行數值模擬,併運用Fluent軟件進行模擬計算,得齣瞭船員艙室的溫度場和速度場的分佈。由艙室溫度分佈均勻和無明顯送風下墜和射流冷風感,得齣誘導型變風量末耑和帶熱交換器動力型末耑送風方案都能滿足艙室舒適性要求,為變風量末耑裝置在艦船上更好地使用提供瞭理論依據。

Types of variable air volume air conditioning system terminal boxes are various, but whether all of them can be used in ships and can save energy is the industry concerns. This article studies the using of terminal boxes in the ships air conditioning. The model takes into account of k-e model with using of Fluent, temperate fields and velocity fields in the crew cabin are obtained. By the cabin temperature distribution and no significant air fall, jet cold feeling. As a result ,come inducible VAV and the new style of fan powered box with air heat exchanger solutions can meet thermal comfort of cabin environment ,which provide a theoretical basis for all kinds of VAV terminal boxes to better use on the ships.
