资源简介：
A compact torsionally oscillating crystal viscometer was used to measure viscosity coefficients of R 32, R 134a and R 1234ze(Z). To derive viscosity coefficients, resonance frequencies and bandwidths of the crystal were automatically measured with a developed measuring system and its software. Viscosity data of R 32, R 134a and R 1234ze(Z) were measured at temperatures ranging from 303 to 450 K at pressures up to 20 MPa in their liquid regions. The uncertainty of the measurements was estimated to be about 5 %. The experimental data of R 134a were compared with calculated data from a correlation.
