Thermophysical properties of the refrigerant mixtures R507, R410A and R404A from dynamic light scattering.

Author(s) : FRÖBA A. P., WILL S., LEIPERTZ A.

Summary

Thermal diffusivity and sound velocity have been obtained by light scattering from bulk fluids for both the liquid and vapour phases under saturation conditions over a temperature range from about 290 K up the liquid-vapour critical point. By applying the method of dynamic light scattering to a liquid-vapour interface, also called surface light scattering, the saturated liquid kinematic viscosity and surface tension can be determined simultaneously. These properties have been measured from about 240 to 330 K.
