ABSTRACT
1,1,1,2,3,3,3-Heptafluoropropane (R227ea) is considered an alternative fluid in the refrigeration and air conditioning industry to replace traditional CFC refrigerants. Limited information is available in the literature about the PFT behavior of this fluid, so the purpose of the experimental analysis described in the present paper is to provide a set of compressed liquid density data. A vibrating tube densimeter (Anton Paar DMA 512) was used to measure the density of R227ea along six isotherms between (283.15 and 333.15) K and up to 35 MPa, with an estimated uncertainty of about 0.05 %. Saturated liquid densities were extrapolated from the measured data using a polynomial. The results of the compressed liquid density measurements and the extrapolated values of saturated liquid density were correlated with fitting equations and compared to existing experimental data sets.
