摘要：根据渔船节能减排的需求，设计了一种新型的渔船氨水吸收式制冷系统，利用渔船余热实现渔船的制冰、蓄冷和工作区域供冷，解决了渔船上鱼类的保鲜和冷藏，改善船上工作环境。建立了渔船氨水吸收式制冷的热力学模型和性能评价指标，在此基础上采用序贯模块法迭代求解，实现了渔船氨水吸收式制冷系统的仿真，同时进一步研究了不同操作条件下制冷系统的运行特性，最终获得了烟气温度、流量和三通阀开度等参数变化时各用户端功率的变化规律。该系统模型可指导渔船制冷系统的功率分配，为优化渔船制冷系统的运行参数、实现低碳渔船提供理论基础。

Abstract: A new type of fishing boat ammonia-water absorption refrigeration system considering the characteristics of fishing boat was designed. It drove by exhaust gas from the fishing boat’s engine, it could realize ice-making, cool storage and environment cooling, the fishing boat refrigeration system could not only serve for fish cold storage and fish fresh-keeping, but also serve for fishing boat’s environment cooling. The thermodynamic mathematical model and evaluation index for fishing boat ammonia-water absorption refrigeration system were established, the sequential modular approach was applied to solving ammonia-water absorption refrigeration system, so the simulation of ammonia-water absorption refrigeration system for fishing boat was realized. The refrigeration system’s operation characteristics under different gas parameters and different three-way valve’s operating conditions were investigated. Results shown that the system’s operation characteristics could not only give fishing boat refrigeration system’s power assignment, but also lay theoretical foundation for fishing boat refrigeration system’s operation optimization and low carbon emission fishing boat.
