【摘要】：以系統(tǒng)凈功、不可逆能量損失等作為目標參數(shù),建立海洋溫差能ORC系統(tǒng)多目標函數(shù)優(yōu)化體系,研究蒸發(fā)溫度、冷凝溫度、工質(zhì)流量、溫海水出口溫度等對系統(tǒng)性能的影響。研究結(jié)果表明:存在最優(yōu)參數(shù)值使得系統(tǒng)性能最優(yōu);冷凝溫度越高,最優(yōu)蒸發(fā)溫度越高,系統(tǒng)目標值越大,系統(tǒng)性能越差;文章所選取的6種工質(zhì)中,R227ea能耗最低,R141b能耗最高;溫海水的適宜出水溫度為19~20℃。
[Abstract]:Taking the net work and irreversible energy loss of the system as the target parameters, a multi-objective function optimization system for marine thermo-energy ORC system is established. The effects of evaporation temperature, condensation temperature, working fluid flow rate and outlet temperature on the performance of the system are studied. The results show that the system performance is optimal with the existence of optimal parameters, the higher the condensation temperature, the higher the evaporation temperature, the greater the target value of the system and the worse the system performance, and the lowest energy consumption of R227ea is the highest among the six working fluids selected in this paper. The optimum effluent temperature of warm seawater is 1920 鈩，
