| 概要 |
The parametric analysis of combined system having gas turbine, supercritical carbon dioxide (sCO_2) Brayton cycle, organic Rankine cycle for power and cooling by vapor absorption refrigeration are stu...died here. The results provide valuable insights into the exergetic efficiency, exergy destruction, power output, efficiency and refrigeration effect. The combined system offers the maximum exergetic efficiency of 42% at cycle pressure ratio 14, turbine inlet temperature 1400 K, while at these operating states, the power output is 484.38 kW. The variables cycle pressure ratio, turbine intake temperature, and evaporative temperature have all been analyzed for their impact. The GT-sCO_2-ORC cycle's power output goes up from 250.53 kW to 484.38 kW and its efficiency goes up from 45.68% to 54.59%, when the cycle's pressure ratio is adjusted from 6 to 14. Maximum exergy destruction of 26% is found in condenser of ORC cycle and negligible in pump. The results of the study demonstrate that, under conditions of 55-60%, LiBr concentration, the coefficient of performance and refrigeration effect of the system exhibit improvement as the generator & evaporator temperature increases. The coefficient of performance and refrigeration effect reach their minimum values i.e. 0.702 and 283.91 kW, respectively at an evaporator temperature of 5℃, whereas their maximum values i.e. 0.775 and 313.39 kW respectively are seen at an evaporator temperature of 15℃.続きを見る
