Design Considerations for Refrigeration Cycles

Advanced Exergoeconomic Analysis of C3MR, MFC and DMR ‎Refrigeration Cycles in an Integrated Cryogenic Process

C3MR, MFC, and DMR processes in an integrated LNG-NGL-NRU structure are investigated using the conventional and advanced exergy and exergoeconomic analyses. The results of advanced exergy analysis reveal that in most of the equipment, the highest amount of irreversibility is occurred because of endogenous exergy destruction. In C3MR process, compressor C5 with 9730 kW; in MFC process, compresso...

Thermodynamic and Thermoeconomic Optimization of an Absorption Refrigeration System integrated with Refinery Crude Oil Furnace

In the present study, exhaust gases from Tehran refinery crude oil furnace are used in a Heat Recovery Steam Generator (HRSG)for generating steam. Then, the steam is directed to a double effect absorption refrigeration cycle to produce cooling. To meet the object, mass and energy balance equations of the coupling is carried out for both the HRSG and the absorption chiller and unknown thermodyna...

Thermodynamic analysis of an absorption refrigeration system with ionic-liquid/refrigerant mixture as a working fluid

Thermodynamics of an ionic-liquid (IL) based absorption refrigeration system has been numerically analyzed. It provides an alternative to the normally toxic working fluids, such as the ammonia in conventional absorption systems. The use of ILs also eliminates crystallization and metal-compatibility problems of the water/LiBr system. Mixtures of refrigerants and imidazolium-based ILs are theoret...

Simultaneous optimal design of multi-stage organic Rankine cycles and working fluid mixtures for low-temperature heat sources

Energy recovery is a process strategy seeking to improve process efficiency through the capture, recycle and deployment of normally neglected low energy content sources or streams. By proper optimal process design, such low-temperature energy sources can be a feasible and economical manner of approaching the energy recovery issue. In particular, when Rankine cycles with mixtures as working flui...
