N2 - On the basis of the concept of Pareto optimum solution to the multi-object function and the comprehensive considerations of both annual cash-flow and energy utilization efficiency, a double-efficiency diagram of annual cash flow-exergy efficiency (CE) was proposed by the implementation of the multi-objectives genetic algorithm. For the CE diagram, the graphing method was described, and the meaning of endpoints was analyzed. 30 chlorine-absent working fluids were employed and tested under different working conditions. Typical ORC systems (i.e. basic organic Rankine cycle, BORC, and organic Rankine cycle with internal heat exchanger, IHORC) were both studied as examples. The proposed method can be used for working fluids selection and thermodynamic system comparison, and case studies were given by segmenting the CE diagrams into different parts. In addition, an outlook for the further applications of CE was presented. The proposed quantitative method would be applicable to any closed loop waste heat recovery thermodynamic system and working fluids.
