氟乙烷(HFC161)热物性实验研究

The experimental research about thermophysical property was carried out for difluoroethane (HFC161). The the viscosity, thermal conductivity, adiabatic index, critical parameters, the saturated vapor pressure, heat of vaporization, heat capacity and pvT were measured for HFC161 respectively. All these thermophysical properties of HFC161 are solid, reliable basis for further research and engineering application. At the same time, the experimental method and apparatus of thermophysical properties of fluid，especially for critacal parameters and adiabatic index, were explored and improved to form a perfect, high-precision series of experimental platform for thermophysical property measurement. On this basis, the new green refrigerant with independent intellectual property rights, which is comprised of HFC161 and other refrigerants, is developed.
