| 摘 要： | 本文基于朗肯循环,结合闭式OTEC系统模型,分别以氨、R22和R134a为循环工质,在温海水及冷海水温度相同的前提下,以装机容量50 kW的OTEC电厂为研究对象,开展工质种类对OTEC系统性能影响的研究。结果表明,氨系统较其他两个系统所需工质流量小、换热面积小、厂自用电少、朗肯循环净效率及供电效率高;R22系统与R134a系统相比,R134a系统供电效率大,其环保性好,是R22较好的替代工质。

| Abstract: | Based on the Rankine cycle and combined the closed -cycle OTEC system model,with ammonia, R22 and R134a,at the same warm and cold water temperature,with the power 50kW OTEC installed capacity for research object.It studied the influence of working fluid type on system performance of the ocean thermal energy conversion.The results show that the ammonia system requirements than the other two systems working fluid flow rates,heat transfer area is small,since the power plant less the net Rankine cycle efficienc... |
