| 英文摘要 | The critical temperature (t-c) and boiling temperature (t-b) of working fluids are important selection criteria for the organic rankine cycle (orc) system. in this study, the ratio of t-b and t-c (t-br) and the vapor expansion ratio (ver) model based on claussius-claperyron equation are introduced to compare and explain their effects on the maximum net output power (w-net,w-max) and ver of orc. the investigation of 267 working fluids is done at four heat source temperatures (t-5). maximum vapor enthalpy method is proposed to determine the upper limit of the evaporation temperature, which is the optimization parameter for maximizing the net power output. at low t-5 (423.15 and 473.15 k), the obvious relationships between w-net,w-max and t-c are independent of t-br. therefore, t-c enables to select working fluids with high w-net,w-max. however, at high t-5 (523.15 and 573.15 k), t-br is essential to exclude working fluids with optimum t-c (0.89 - 0.90t(5)) but low w-net,w-max. moreover, at a given t-c, high t-b or t-br indicates high ver. consequently, t-b or t-br is suitable to be used as the second indicator. this paper proposes the optimal combinations of t-c and t-b and the developed composite indicator for selection of working fluids.
