Energetic and exergetic analysis of new dual evaporator CO2 transcritical refrigeration cycle.

Author(s) : YATHREB E., KAIROUANI L., NAHDI E.

Summary

In this work, a new dual-evaporator CO2 transcritical refrigeration cycle with two ejectors is proposed. In this new system, we proposed to recover the lost energy of condensation coming off the gas cooler and operate the refrigeration cycle ejector free and enhance the system performance and obtain dual-temperature refrigeration simultaneously. The effects of some key parameters on the thermodynamic performance of the modified cycle are theoretically investigated based on energetic and exergetic analyses. The simulation results for the modified cycle show indicate more effective system performance improvement than the single ejector in CO2 the vapor compression cycle using ejector as an expander. The exergetic analysis for each component at optimum gas cooler pressure indicates that the condenser compressor, two ejectors and expansion valves contribute main portion to the
total system exergy destruction. The performance characteristics of the proposed cycle show its promise in dual evaporator refrigeration system.
