摘要

渔船通常需要带冰或使用压缩式制冷来满足渔获冷藏保鲜的需要，而渔船发动机尾气中有大量的热能被排放到环境中去，利用渔船发动机尾气余热制冷是一种既经济又节能的好方法。本文介绍了吸附式、吸收式和喷射式三种热能驱动的制冷循环，并针对渔船制冰工况对这三种循环在渔船中应用的优缺点进行了分析；重点讨论了使用喷射式制冷技术对渔船现有压缩式制冷系统进行改造的可行性。研究结果表明，将喷射制冷与压缩制冷结合，可减少渔船制冷系统燃料消耗54.5%，在1年内即可收回改造成本。

Abstract

Ice and compression refrigeration are normally used to preserve caught fish on fishing vessels. At the same time

waste heat dissipated in hot exhaust gas on fishing vessels is rejected to the atmosphere. Utilizing the vast amount of the waste energy for refrigeration is both economical and energy saving. Three kinds of heat driven refrigeration cycles as adsorption

absorption and ejection are introduced in this paper. Advantages and disadvantages of the three cycles are analyzed based on the working condition of ice making on fishing vessels. Emphases have been made on the feasibility of transforming the existing compression refrigeration cycle on fishing vessels by ejection technology. The result shows that 54.5% of fuel for refrigeration system can be saved after combining ejection and compression cycle and the transforming cost can be recovered in 1 year.
