摘　　要：受传统化石能源日趋枯竭和环境污染的影响,海洋能作为一种清洁可再生能源得到了广泛关注。海洋温差能作为海洋能的重要组成部分,其储量和可转化电能巨大,且发电波动小、能量密度高,积极开发海洋温差能资源对实现科技兴海战略具有重要意义。海洋温差热力循环是海洋温差能开发利用的关键技术,其循环效率的高低直接决定了海洋温差发电系统的技术和经济性。本文综述了海洋温差能发电热力循环技术研究现状,对其基本原理及形式、热力循环构架、循环工质和热力学分析方法进行了详细阐述,并对海洋温差能发电热力循环技术进行了深入分析和展望。As the impact of the fossil energy crisis and environmental pollution, ocean energy is attracted extensive attention as it is a clean and renewable energy. Ocean thermal energy is an important part of ocean energy. Due to its stable large reserves, actively developing ocean thermal energy has a significant meaning for the strategy of enhancing the ocean by science and technology. Thermodynamic cycle is the key technology of utilizing the ocean thermal energy, its efficiency determines the technical and economic characteristics of ocean thermal energy conversion system. This paper reviews the development of power generation of ocean thermal energy conversion and concludes the basic principle, types of thermodynamic cycle, working fluids and methods of thermodynamic analysis of ocean thermal energy conversion. According to deep analysis, the research direction is proposed.
