It also introduces the theory of ORC cycle，Kalina cycle and the Uehara cycle and how to choose working medium in ORC cycle. It analyzes and calculates the efficiency of ORC cycle at the same heat source temperature, cold source temperature, expander efficiency and pump efficiency and at different working medium and the the efficiency of ORC cycle at different expander efficiency and he the efficiency of ORC cycle at different heat source temperature. It also analyzes the theoretical efficiency and the actual efficiency (with a expander and pump efficiency of 70%)of Kalina cycle at different ammonia mass fraction. It also analyzes the theoretical efficiency and the actual efficiency (with a expander and pump efficiency of 70%)of Uehara cycle at different ammonia mass fraction..关键词：海洋温差能、有机朗肯循环、Kalina 循环、上原循环、循环效率Keywords: OTEC、ORC cycle、Kalina cycle、Uehara cycle、cycle efficiency目录摘要............................................................................................................................................................1Abstract......................................................................................................................................................1关键词...........................................................................
