The energy and exergy analysis of a novel cogeneration organic Rankine power and two-stage compression refrigeration cycle
The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...
متن کاملDynamical modeling and thermo-economic optimization of a cold room assisted vapor-compression refrigeration cycle
A cold room assisted vapor-compression refrigeration cycle is dynamically modeled in a year and optimized. Total annual cost (TACO) and coefficient of performance (COP) are selected as two objective functions. Both cold room and refrigeration cycle parameters are considered as design variables. Moreover, three working fluids included R22, R134a and R407c are examined. The optimum Pareto front r...

متن کاملParametric Assessment of a Novel Geothermal Multi-Generation Equipped with Dual-Organic Rankine Liquefied Natural Gas Regasification Cycle Using Advanced Exergy and Exergoeconomic-Based Analyses
This research is concerned with the design and analysis of a geothermal based multi-generation system by applying both conventional and advanced exergy and exergoeconomic concepts. The proposed energy system consists of a dual-organic Rankine cycle (ORC) to vaporize liquefied natural gas (LNG) and produce electricity. A proton exchange membrane(PEM) electrolyzer is employed to produce hydrogen ...
متن کاملThermodynamic Performance of Regenerative Organic Rankine Cycles
ORC (Organic Rankine Cycle) has potential of reducing consumption of fossil fuels and has many favorable characteristics to exploit low-temperature heat sources. In this work thermodynamic performance of ORC with regeneration is comparatively assessed for various working fluids. Special attention is paid to the effects of system parameters such as the turbine inlet pressure on the characteristi...
