چکیده انگلیسی
In contrast to pure ammonia, some additives into it may provide better solubility of the mineral oils, higher refrigeration capacity and lower discharge temperature of the compressor. In this paper, the vapor liquid phase equilibrium for the ammoniaâ+â1,1-difluoroethane system at temperatures ranging from 253.150âK to 293.150âK were studied. The Peng-Robinson equation of state with the Huron-Vidal mixing rule involving the non-random two-liquid activity coefficient model was employed to describe the VLE behavior of the system concerned. The maximum average absolute relative deviation of pressure and average absolute deviation of vapor phase are 0.31% and 0.009, respectively. A positive azeotropic behavior was exhibited at the experimental temperature range.
