Investigation Of Dehumidification Process On Falling-Film Of LiCl Solution

The traditional compression refrigeration systems consume plenty of electrical energy. With the development and widely application of the technology of refrigeration and air conditioning, the traditional way of refrigeration has resulted in two severe problems concerned by people presently, which are the issues about energy and environment. The expense of plenty of electrical energy leads to the issue about energy. The issue about environment is provoked by the extensive use of traditional refrigerant-Freon. Liquid dehumidification was driven by low temperature heat resource like solar energy. What's more, there is no Freon refrigerant in the new system and no pollution effect.This article introduced the background and developmental condition of the liquid dehumidification and expatiated on the theory of the dehumidification system. The liquid dehumidification facility was set up.This thesis observed the change of dehumidification in the different inlet condition. The result of the absorption was accorded with the predictions. Air flow rate, liquid temperature and concentration had a great affect on dehumidification; liquid flow rate, air temperature and humidity had less effect on dehumidification.The effect of each inlet condition on regeneration in tube falling-film was study in the article. The result of the absorption was accorded with the predictions. The mass of water evaporation was heavy influenced by the liquid temperature and concentration; the air condition had less effect on regeneration.The mathematic models were established according to the packed tower dehumidification and tube falling-film regeneration, which described heat transfer and mass transfer about the countercurrent flow in the dehumidifier and regenerator of the air conditioning system. The affect of all inlet condition on dehumidification and regeneration was study based the models. The result of the absorption was accorded with the predictions. Air humidity, liquid temperature and concentration had great affect on dehumidification; the mass of water evaporation was heavy influenced by the liquid temperature and concentration; other factor had less effect on dehumidification and regeneration.
