摘要
在仲氢绝热转化制冷技术研究的基础上,建立了仲氢到正氢的连续转化过程数学物理模型,仿真计算分析了连续转化制冷量数据,并提出了仲氢转化制冷技术用于液氢高效储存的技术途径,分析了用于液氢储存时仲氢转化制冷过程中的温度和焓值变化趋势。结果表明,仲氢的连续转化的确可以产生很大的制冷量,可以设计成液氢储罐的冷屏,用于吸收环境对于储罐的漏热,从而可以减少液氢储存的蒸发损失。
Based on the research of parahydrogen refrigeration technology with conversion adiabatically,the model of parahydrogen refrigeration with conversion continually was founded in this paper. The conversion process was analyzed and the data of refrigerating capacity was obtained. The results show that there is large refrigerating capacity during parahydrogen continual conversion process,and this can be designed as a vapor cold shell (VCS)of the liquid hydrogen vessel to decrease the evaporation loss.
