研究目的
To propose a novel solar power assisted multigeneration system, consisting of the concentrating collector, Rankine cycle with high and low pressure turbines, ORC with two turbines, PEM electrolyzer, DEAC process, dryer and heat pump. The energetic and exergetic studies are conducted to provide a better investigating of integrated system efficiency.
研究成果
The thermodynamic analysis shows that the solar-assisted multi-generation systems have good potential in terms of energy and exergy efficiency. The highest rate of irreversibility is in the parabolic dish collector, and the lowest is in the dryer. The energy and exergy performance of the overall system are 48.19% and 43.57%, respectively.
研究不足
The study assumes steady-state operating conditions, negligible kinetic and gravitational potential energy changes, and neglects heat losses and pressure drops in the pipes. The isentropic efficiencies of turbines and pumps are assumed, and the energetic performance of PEM electrolyzer is accepted as 0.60.
