“…The main disadvantage of the implementation of hydrocarbons mixtures is their flammability (BSI, 2004). For the case of drop-in in domestic refrigeration with medium-class flammability refrigerants, like R152a and R32, the average COP obtained using R152a is higher than the one using R134a, while the average COP of R32 is lower than the one using R134a (Bolaji, 2010). R1234yf has been proposed as a replacement for R134a in mobile air conditioning systems (Spatz and Minor, 2008), and its similar thermophysical properties makes R1234yf a good choice to replace R134a in other applications of refrigeration and air conditioning.…”

“…The results indicated the successful application of the mixture of propane and butane for their placement of CFC-12 in domestic refrigerators. Jung et al [6] examined the performance of a mixture of propane and isobutane used in refrigerators. A thermodynamic analysis showed that the coefficient of performance of the system was increased up to 2.3% as compared toCFC-12 when the test was run at a mass fraction of propane ranging between 0.2and 0.6.…”

“…In 1997, HFCs were considered as greenhouse gases and currently they are target compounds for greenhouse gases emission reduction under the Kyoto Protocol (GCRP, 1997). In this way, the growing international concern over relatively high GWP refrigerants has motivated the study of low GWP alternatives for HFCs in vapor compression systems [1][2][3][4][5].…”

This paper presents thermodynamic cycle analysis of mobile air conditioning system using HFO1234yf as alternative replacement for HFC-134a. Under a wide range of working conditions (Varying Condensing temperature, Evaporating temperature, Sub cooling and sub heating with Internal heat exchanger (IHX) and without internal heat exchanger) on simple vapor compression system, we compare the energy performance of both refrigerants -R134a and HFO1234yf.Result shows that without using an Internal heat exchanger, At lower condensing temperature (35 o C), Mass flow rate increases about 27-32%, refrigerating effect decreases 22-25%, co mpressor work increases 4-6% and COP decreases about 3-5%.While at higher condensing temperature (55 o C), mass flow rate increases about 35-42%, refrigerating capacity decreases 27-30%, and compressor work increases 8-13% and COP decreases 7-10%.Using an internal heat exchanger (IHX), these differences in the energy performance are significantly reduced.At lower condensing temperature (35 o C), mass flow rate decreases about 18-22%, refrigerating capacity decreases 15-18%, compressor work increases 1-3% and COP decreases about 2-3% and At higher condensing temperature (55 o C), mass flow rate decreases 23-28%, refrigerating capacity decreases 18-22%, compressor work increases 5-8% and COP decreases about 4-7%.The energy performance parameters of HFO1234yf are close to those obtained with HFC-134a at Low condensing temperature and making use of an IHX. Even though the values of performance parameters for HFO1234yf are smaller than that of HFC-134a, but difference is small so it can be a good alternative to HFC-134a because of its environmental friendly properties with introducing IHX.
