New experimental data on the thermal conductivity and the viscosity of low-GWP refrigerants such as HFOs are reported in order to contribute to the development of low-GWP refrigeration/heat pump systems. Accurate data on thermodynamic and transport properties are indispensable to design and to manufacture the systems with high efficiency. However, there are only limited data on the properties. In this study, the thermal conductivity and viscosity of low-GWP refrigerants were measured by a transient hot-wire method and tandem capillary tubes method respectively with wide temperature and pressure range covered from subcooled liquid to superheated vapor region.
