基于海底黑烟囱的海洋温差发电热力循环系统研究
Study of thermodynamic cycle of OTEC based on black smoker chimney
摘要
Abstract
The OTEC system of the paper studying is different from the traditional OTEC system, which takes the marine geothermal energy (black smoker chimney) as the heat source, takes cold water of deep sea as the cold source. The paper analyzes and calculates some parameters of open-system which uses water vapor as the working fluid and the close-system which uses pure ammonia as the working fluid, such as thermal efficiency, heat load of condenser and evaporator, pump power, and the system net power. The results show that;comparing with the close-system which uses pure ammonia as the working fluid, the high power of hot water pump is the key problem for the open-system, as well as reducing the temperature of hot water and increasing the flash evaporation pressure are disadvantageous ; but water vapor as the working fluid helps reducing the load of condenser and evaporator, which is very advantageous for heat exchanger design.关键词
