This study analysed cooling performance in the fish holds of 30 gross tonnage fishing vessels to optimise the temperature distribution through the cargo volume in the fish hold. A field survey determined the calculation parameters and the fish hold's geometric design. The fluid flow characteristics and product cooling times were determined using a computational fluid dynamic simulation and a performance coefficient of the refrigeration cycles. The simulation result shows that the fastest cooling time occurs when the velocity inlet is 8 m/s at 100% cargo loads. The estimated cooling time until the product load reaches a temperature of −5°C is 2 hours 15 minutes. The required power consumption of the compressor is 3.22 kW and of the condenser is 16.29 kW. The refrigeration system performance coefficient is 4.06. These performance results indicate that the designed fish hold is effective in fish cooling.

本研究分析了 30 艘总吨位渔船鱼舱的冷却性能，以优化鱼舱货物体积的温度分布。实地调查确定了计算参数和鱼舱的几何设计。使用计算流体动力学模拟和制冷循环的性能系数确定流体流动特性和产品冷却时间。仿真结果表明，在 100% 货物负载下，当速度入口为 8 m/s 时，冷却时间最快。产品负载达到 −5°C 温度之前的估计冷却时间为 2 小时 15 分钟。压缩机所需的功耗为 3.22 kW，冷凝器的功耗为 16.29 kW。制冷系统性能系数为4.06。
