From the point of view of low global warming potential, 2,3,3,3 tetrafluoropropene (CF3CF=CH2 : HFO-1234yf) is expected as the new alternatives of CFC refrigerants. However no experimental data and correlation for this substance can be available. In this paper, the experimental data, correlations, and equation of state for HFO-1234yf measured by our group are summarized briefly. In addition, the newest saturation tables as well as pressure-enthalpy diagram of HFO-1234yf are shown calculated the equation of state formulated by our group. The COP for basic refrigeration cycle by using the HFO-1234yf is also discussed against the HFC refrigerants.
