| 摘 要： | 为了筛选出适宜于海洋温差热力发电有机朗肯循环的工质.采用PR状态方程计算11种低沸点有机流体工质在闭式海洋温差有机朗肯循环中的热力性能.结果表明,随着工质临界温度升高,循环热效率总体呈上升趋势.正丁烷具有较高的循环热效率,其蒸发压力较低、凝汽压力比较适中,比较适合用作海洋温差发电有机朗肯循环的工质.

| Abstract: | Aiming to make a suitable selection of the working fluids for Ocean thermal energy conversion(OTEC) power generation organic Rankine cycle,the PR equation of state was adopted to calculate the thermal performances of OTEC organic Rankine cycle using each of eleven dry fluids.The following conclusions were drawn: as the critial temperature of the selected fluid increases,the thermal efficiency of the Rankine cycle will rise as a whole.Fluid R600 exhibits considerably high values of thermal efficiency,meanwhi... |
