摘要

The following tasks have been solved in the current study: (a) film desorption from a solution with one volatile component; and (b) thermal stage of bubble growth at desorption from a binary solution on the basis of Labuntsov model [ 1 ]. It is shown that the rate of bubble growth tends to zero because of volume limitation of solution involved into heat and mass transfer. This phenomenon can block the process of bubble desorption, and this should be taken into account, when designing the absorption thermal transformers. Therefore, it is necessary to ensure in terms of engineering the condition of film evaporation at suppression of nucleate boiling.
