Densité et température de cristallisation d'une solution aqueuse de bromure de lithium.

Lithium bromide aqueous solution for absorption air-conditioning systems was examined in detail with regard to its densities and crystallization temperatures. The vibratory density meter with a U-shaped tube was used for this highly precise experiment. The density of water for reliability test of this experimental set-up has a maximum deviation of 0.43 kg/m3. The minimized deviation suggests that the uncertainty of the density measurements of lithium-bromide aqueous solution would not be greater than plus or minus 0.5 kg/m3. A density correlation was developed using the data obtained. The correlation reproduces the measurement densities plus or minus 0.5%.
