“…Several works can be found in the literature presenting theoretical studies to determine the feasibility of direct substitution (or with slight modifications) using R1234yf in facilities working with R134a (Akasaka et al, 2010), being most of them based on mobile air conditioning systems. Lee et al (2012), measured theoretically the drop-in performance of R1234yf in a simple bench tester and examined the possibility of substituting R134a in mobile air conditioning systems.…”

The viscosity of 2,3,3,3-tetrafluoropropene (HFO-1234yf) has been successfully correlated with the extended corresponding states (ECS) model for transport properties. The thermodynamic equation of state developed in our earlier work forms the basis of this work. The viscosity correlation presented here is valid for temperatures from 260 K to 340 K and for pressures up to 20 MPa. The correlation can be applied to both liquid and gas phases in a single procedure. The estimated uncertainties are 2 % for liquid phase and 2.5 % for gas phase, which roughly correspond to experimental uncertainties.

“…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.
