Thermo physical properties of acetone–zinc bromide for using in a low temperature driven absorption refrigeration machine

Thermal physical properties (vapor pressure, density, viscosity, specific heat capacity, specific electrical resistance and specific enthalpy of mixing) of the solution acetone–zinc bromide, which will be used as a working solution in an absorption refrigeration machine, are measured and analyzed. The experimental data were correlated with high accuracy. The required state diagrams (log p, T and h, T) for this solution as well as the log P, h-diagram for the pure acetone are calculated, represented, correlated and discussed. The results indicate that the solution acetone-zinc bromide might be suitable as a working solution to operate an absorption refrigeration machine at low temperature.
