Pump Lithium Bromide Absorption Air Conditioner Simulation Study

The technology of the large-size LiBr absorption refrigeration is already very perfect, but the cooling load all are big and is not fitful for a situation of a small cooling load. So, according to our national nature gas industry' station and future, combining itself characterize of air-condition, suggesting to develop the application of a sort of LiBr absorption air-condition which is drived directly by heat source coming from nature gas'burnning .In the text, Baed on the no-pump LiBr absorption air-condition will break into the family air-condition market, comparing it to the air-condition drived by electricity on environmental protection, economize on energy and economy. We can draw a conclusion that the air-condition have a good rivalrousness. the air-condition enlarge space of absorption chiller utilising nature gas.In the text applying the theory of two-phase flow'press-drop and diversion-phase model, having a analysis to the press characterize of the important part namely the bubble pump of the no-pump LiBr absorption air-condition , and set up the relational mathematical model. Program of the model was built and having a mathematical simulation. And perfoimed a detailed analysis of the simulation result of the important characterize parameter, the height of advance, the height of the absorption's liquor face, and the difference of the LiBr density.In the text thermodynamics and heat transfer calculation of the no-pump LiBr absorption refrigeration were performed, and carried out the values of various state point, the heat load and the areas of each apparatus. Based on the calculated result, according to the principle of mass conservation, energy conservation and the phase equilibrium, a thermodynamics model of the system was set up. A program was designed from the model, carried a simulation under different operation states. Having a analysis and getting the system running performance under different operation states.
