Fuzzy thermoeconomic analysis in refrigerant selection.

Author(s) : ARTEMENKO S., BODAREV D., KHMEL'NJUK M., et al.

Summary

The refrigerant selection in the vapour compression refrigeration cycles has been studied as a fuzzy thermoeconomic optimization problem. Three criteria: thermodynamic (COP), economic (life cycle cost), and ecologic (GWP) are chosen as target functions. The decision variables X as an information characteristic of desired refrigerant are presented by its critical parameters and normal boiling temperature. Local criteria are expressed via thermodynamic properties restored from information characteristics of refrigerant X, as well as life cycle costs are calculated by the standard economic relationships. GWP values are taken from the refrigerant database. Class of substances under consideration is presented by the possible alternative refrigerants for the R-12 and R-22 replacements.
