Résumé

This paper raises a possibility of using falling film style generator in lithium bromide absorption refrigeration systems. The mathematical model is developed to express the heat and mass coupled problem of laminar falling film evaporation in vertical tube, and in which the factor of mass transfer is taken into account in heat transfer performance calculation. The temperature and concentration fields are calculated, and the factors such as Re number, heating flux, the inlet concentration and operating pressure which can affect the heat and mass transfer performance in laminar falling film evaporation are tested. Analyses of the heat and mass transfer mechanism show that diffusion term plays an important role in falling film evaporation process.
