中文摘要: 根据对有机朗肯循环工质的选取原则,选出7种工质作为备选工质,建立了有机朗肯循环的热力学模型,并基于热力学第一定律和第二定律对其热力过程进行了计算分析,分别对7种工质的蒸发压力、单位工质净功量、不可逆损失、热效率、(火用)效率进行对比,结果表明,在给定的热源范围内,R141b各项性能最佳,R1233zd其次,而R1234yf和R1234ze表现较差.
Abstract:Based on the principle of selecting working fluid for organic Rankine cycle, seven working fluids are selected as alternative refrigerants.A thermodynamic model of the organic Rankine cycle is set to analyze the thermodynamic process.According to the change of the evaporation temperature, seven kinds of refrigerants are compared and analyzed in evaporation pressure, net power, thermal efficiency, irreversible loss and exergy efficiency to evaluate the performance.Comprehensive comparison shows that in the given range of heat source.The property of R141b is the best, R1233zd is the second, R1234yf and R1234ze show poor performance.
keywords: waste heat recovery organic rankine cycle working fluid cycle efficiency exergy efficiency
