Abstract

On account of the influence of the heat transfer processes on cycle performance in organic Rankine cycle （ORC）, an addition organic Rankine cycle （AORC） is proposed in this paper, which is similar to but different from the ORC with non-azeotropic mixtures, and can operate independently for each working fluid. In AORC, the stacking heat transfer processes with series or parallel by the working fluids can form effect of temperature glide similar to the non-azeotropic mixtures. Due to the independent operation of each working fluid, the temperature glide can be adjusted to reduce the heat transfer temperature difference with external heat/cold sources, thus improve the heat transfer matching, and improve the performance of the AORC. The thermodynamic performance of AORC consisted of two working fluids as example is analyzed and compared with the conventional ORC. Results shown that AORC is not a simple linear superposition of basic ORCs of various working fluids, but a optimal superposition. Compared with the conventional ORC, a maximum increase of the net output power of AORC can be reached 34.48%. But when the heat source temperature is higher than the shift-temperature of the high-temperature cycle of the working fluid, the AORC will tend to approach the basic ORC of the same working fluid.

Key words
