摘要: Abstract Dual-pressure evaporation cycle is an emerging type in the organic Rankine (ORC) that can remarkably reduce irreversible loss during heat absorption process and improve adaptability to various sources. Introduction of zeotropic mixtures dual-pressure ORC presents great potential further increase heat-power conversion efficiency due variable phase-change temperature. This study investigated using isobutane/isopentane for sources 100–200 °C. Effects source temperature mixture composition on system thermodynamic performance were analyzed. Application applicable ranges introducing evaluated. Results showed introduction substantially increased power output. The maximum output could by 11.9% 15.2% at most compared with those isobutane isopentane, respectively. It 25.7% single-pressure mixtures. In terms being introduced into ORC, a high critical generally achieve larger range increment
