Abstract

Nonisothermal desorption and crystallization of droplets of aqueous salts solution of H₂O/LiBr were studied experimentally. A droplet was placed on a horizontal heated wall. The initial concentration of salt C₀ varied within 0-53 %. The wall temperature T_w varied within 80-235 °C and ambient air pressure was 1 bar. It was shown that the desorption time t₁ decreases sharply with increasing T_w and at T_w < 150-160 °C. The desorption time t₁ is the time until the onset of crystallization. The desorption time t₁ is quasi-constant at T_w > 160 °C and increases with growth in C₀.
