摘　　要：为提升远洋渔船冷藏舱的制冷能力,更好地满足渔获物转运需求,以某氨制冷南极磷虾冷藏舱为研究对象,基于FLUENT数值仿真方法对其进行优化设计。通过数值仿真计算,引入风量不均匀系数、风量偏差系数和空气龄参数,对舱底各孔的均匀性和舱内空间通风换气效果进行评估,对风机室空气冷却器的摆放位置进行局部优化,提高舱内气流换热能力,减少氨制冷剂的充注量。结果表明,当空气冷却器居中布置时,空气龄为270.2s,舱内气流滞留时间最短,气流换热效果最好。研究成果可供国内大型氨制冷南极磷虾船冷藏舱设计参考。In order to improve the refrigeration capacity of the refrigerated hold of deep-sea fishing vessel and better meet the demand of fish catch transfer,an ammonium refrigerated Antarctic krill refrigerated hold is taken as the research object and optimized based on the FLUENT numerical simulation method.Through numerical simulation,the uniformity of each hole in the bilge and the ventilation effect in the hold are evaluated by introducing air volume non-uniformity coefficient,air volume deviation coefficient and air age parameters.The position of the air cooler in the fan room is locally optimized to improve the heat transfer capacity of the air flow in the hold and to reduce the ammonia refrigeration charge.The results show that when the air cooler is arranged in the center,the air age is 270.2 s,the hold air residence time is the shortest,and the air heat transfer effect is the best.The research results can be used as a reference for the design of refrigerated holds of large ammonia-cooled Antarctic krill ships in China.
