摘　　要：为有效利用渔船烟气和冷却水的余热,本文采用有机朗肯-朗肯系统进行制冰,建立了系统的热力学模型,研究了系统的性能参数和影响因素,评价了单位质量热水以及单位功率热源的制冰能力。结果表明:余热温度和冷凝温度对系统性能有重要影响,而冷凝器的过冷温度对系统性能的影响很小。在热源温度为100℃,冷凝温度为40℃时,每吨热水的制冰量为86.4kg/t,单位功率余热每小时的制冰量为2.27kg/(kW.h),论证了有机朗肯-朗肯循环系统用于渔船余热制冰的可行性。To efficiently utilize the waste heat from fishing boats, the organic Rankine-Rankine cycle system was employed to generate ice. A thermodynamic model was developed, and the system performance parameters and influencing factors were researched and the ice making capacity from unit mass hot water and unit power heat source are evaluated. The results show that the temperature of heat source and condensation have an important influence on the system performance;however, the supercooling of condenser has not. The ice quantity generated from per ton hot water is 86.4 kg,and the ice-making rate for unit power hot source is 2.27kg/（ kW · h） ,when the temperature of hot water and condensation are 100℃ and 40℃. A conclusion is draw by the calculation and analysis that using organic Rankine-Rankine cycle for ice making from fishing boats waste heat is feasible.
