Summary
A new low global warming potential (GWP) refrigerant hydrofluoro-olefin 2,3,3,3-tetrafluoropropene (HFO-1234yf) has been developed. HFO-1234yf has a very short atmospheric lifetime of 0.03 yrs and a GWP of 4. In this work the critical temperature, vapour pressure, liquid density, ideal gas heat capacity, liquid viscosity, and surface tension of HFO-1234yf have been measured. A corresponding states equation of state has been regressed using the experimental data. These data allow for the design of new refrigeration systems and performance analysis of HFO-1234yf in existing air conditioning applications. HFO-1234yf has been shown to maintain both the capacity and efficiency previously seen in applications such as mobile air conditioning.
