Description

Various kinds of brine is used as a secondary refrigerant. Recently, some new brine is proposed, and the brine using potassium acetate aqueous solutions is paid to attention because the environmental load can be decreased. We investigated the fundamental properties of potassium acetate aqueous solutions, such as refractive index, density, specific heat and viscosity. The measurements of fundamental properties were performed in the temperature range varied from 5 to 50 °C for measurements of refractive index and specific heat, 0 to 70 °C for density and 0 to 50 °C for viscosity, while the concentration range varied from 0.0 to 50.0 wt% for measurements of refractive index, density and specific heat, 10.0 to 50.0 wt% for viscosity. In addition, the empirical equations of these properties are presented and are in good agreement with experimental results.
