Summary

This paper reports experimental results of the vapour pressure for mixtures of HFC-134a and polyalkylene-glycol (PAG) oil. The vapour pressure has been measured for temperatures from 283.15 K to 333.15 K and pressures up to 1.68 MPa. The mass fraction of HFC-134a in liquid phase ranges from 0.1 to 1 HFC-134a. The uncertainty of the measurements is estimated as plus or minus 15 mK in temperature, plus or minus 8 kPa in pressure and plus or minus 1% in concentration, respectively. The correlation equation that interpolates the experimental vapour pressures as a function of temperature and concentration is also presented for practical use.
