A review on comparative evaluation of R1234yf as alternate refrigerant to R134a in mobile air conditioning system

Mechanical engineering

The HFC emission from automobile air conditioning system is major contributor to global HFC emission. As concerns with environmental aspect low global worming potential refrigerants is extreme need for air conditioning and refrigeration sector. The global warming potential of refrigerant R1234yf is 4 whereas refrigerant R134a with high GWP 1430, and has similar thermodynamic properties to R134a. In the present study thermodynamic properties of a new generation, low GWP R1234yf is compared with different refrigerants. The thermodynamic cycle analysis and experimental analysis of varies research studied here for mobile air conditioning system with refrigerant R1234yf as an alternate refrigerant to R134a over different operating conditions. From the study, it can be summarised, that the energy performance of R1234yf is obtained close results to the system using refrigerant R134a with application of internal heat exchanger at lower condensing temperatures. Hence, even though the performance parameters values for R 1234yf are lower than that of R134a, but the difference is comparatively small, so R1234yf with introducing internal heat exchanger can be a possible good alternative to R134a due to its environment friendly properties.
