摘要: Abstract This paper presents a theoretical framework for the energy and exergy evaluation of basic as well three modified Organic Rankine Cycles (ORCs). The ORCs considered incorporating turbine bleeding, regeneration both them. results demonstrate that evaporator has major contribution in destruction which is improved by increase its pressure. confirm integrated ORC with bleeding highest thermal efficiencies (22.8% 35.5%) lowest loss (42.2 kW) due to decrease cold utility demand high power generation.
