چکیده
The use of new generation refrigerants in heating and cooling systems operating according to vapor compression cycles the preference renewable energy sources is very important reduce negative effects on environment. Here, exergy performance refrigerant R450A R1234ze, which are alternatives R134a, were theoretically examined. Energy analysis system performed under same working conditions (source temperature between -15 15 oC, heat sink constant 30 oC). COP values 2.00, 1.98 1.97, respectively, while source was oC. 4.82, 4.83 4.79, respectively. Under given conditions, highest total destruction occurred at lowest Exergy R1234ze. with capacity R134a According results obtained from analysis, it concluded that R1234ze can be used instead R134a.

This paper investigates the results of a Second Law analysis applied to a mobile air conditioning system (MACs) integrated with an internal heat exchanger (IHX) by considering R152a, R1234yf and R1234ze as low global warming potential (GWP) refrigerants and establishing R134a as baseline. System simulation is performed considering the maximum value of entropy generated in the IHX. The maximum e...
