Author(s) : FILIPOIU C., DOBROVICESCU A., APOSTOL V., et al.

Summary

Comparative analysis of the design and operation of two different solutions for a supermarket cold chain located in Bucharest Romania is presented. The actual system operates with R404A in a single stage for cooling and two stages for freezing while the replacing one (alternative) considers a cascade CO2/NH3 system. The analysis is performed based on the exergy concept. The exergy analysis points out which are the exergy destructions associated to every piece of equipment and processes offering solutions for improvement. Based on the exergetic analysis an exergoeconomic optimization can be developed. The conduct of the cascade system at the variation of the operating parameters is performed.
