Thermophysical properties of some zeotropic and azeotropic mixtures.

Author(s) : LAVRENCHENKO G. K., ZAPOROZHAN G. V., ILJUSHENKO S. V.

Summary

An experimental study of phase equilibrium, density, viscosity and thermal conductivity of the binary mixture R14-R22, an effective refrigerant for microcoolers with the temperature level of 150 K, in a wide range of pressures, temperatures and concentrations has been carried out. According to the experimental results in studying the phase equilibrium, the unified equation of state has been developed, a quality of which is proved by the results of experiments. While determining thermal conductivity a special attention was paid to the critical region. The results of investigation of the thermal conductivity of a new refrigerant R507 - the binary mixture R152a-R218 of an azeotropic composition - are given.
