In this study, energy analysis of a double-stage Organic Rankine Cycle (ORC) was performed using the Engineering Equation Solver program (EES). first and second stages, eight different organic working fluids (R134a, R410a, RC318, R407c, R22, R23, R116, R218) were used in pairs for certain temperature limits. Choosing suitable refrigerant or pair is crucial ORC’s high thermal efficiency net work...

As the energy demand continues to increase across globe, utilisation of waste and sustainable sources, as well implementation diverse systems, are essential [...]

This study develops thermofluidic pump technology that is powered by heat, rather than by electrical or mechanical power. The objective is to improve the performance of heat-recovery by Organic Rankine Cycles, by using a recently-proposed thermofluidic pump. The thermofluidic pump promises low-cost, high-reliability, and, since it does not consume any of the power produced by the expander, impr...

This article provides the dataset of operating conditions of a hybrid organic Rankine plant generated by the optimization procedure employed in the research article "A genetic optimization of a hybrid organic Rankine plant for solar and low-grade energy sources" (Scardigno et al., 2015) [1]. The methodology used to obtain the data is described. The operating conditions are subdivided into two s...

A multigeneration system based on solar thermal energy associated with hot and cold thermal storage is designed and analyzed energetically and exergetically. The system produces electricity, a heating effect, a cooling effect, hydrogen, and dry sawdust biomass as outputs by means of organic Rankine cycles, a heat pump, two absorption chillers, an electrolyser, and a belt dryer. The intermittent...
