Numerical Analysis of Using R449A Refrigerant Alternative to R404A in Cooling Systems: 3E-Analysis (Energetic, Exergetic, and Environmental)

چکیده
The direct impact of refrigerants on the environment is largely dependent magnitude global warming potential (GWP) values. In this regard, fluids with low GWP are very important for environment. Commercial refrigeration accounts about a third world's HFC use. R404A derived near an azeotropic mixture. refrigerant widely used in commercial systems, especially supermarkets. As result use cooling systems high GWP, both indirect and negative effects increase. study, energy, exergy, Life Cycle Climate Performance (LCCP) R449A, which has lower value, can be alternative to refrigerant, were investigated theoretically. Different evaporator temperatures (-30oC -5oC) condenser temperature (30oC) analysis. According results obtained, while mass flow rate R449A approximately 13% than that R404A, its exergy efficiency 5% higher. was found LCCP
