Primary Study On Solar-powered Liquor Air Conditioning System With Energy Storage

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 traditional compression refrigeration systems consume plenty of electrical energy, which has caused the tension of supply and demand of electricity, and that is the issue about energy. The issue about environment is provoked by the extensive use of traditional refrigerant-Freon. The solar-powered liquor desiccant air conditioning system with energy storage can get over the two limitations smoothly, which is droved by low temperature heat resource like solar energy. Therefore power consumption is little. What's more, there is no Freon refrigerant in the new system and no pollution effect. As a new type mode of energy storage, energy with liquor can not only make up the disadvantage of solar energy's discontinuousness, and but also has the function of cutting the apex of electric power and filling the vale of it.This thesis introduced and studied the system flow and the design and betterment of the experiment table, and made the theoretic discussion and studied on several aspects such as dehumidify characteristic of liquor dehumidizer, the running characteristic of dehumidifier, energy storage characteristic with liquor and so on. A quantitative analysis method is put forward about liquor desiccant's dehumidify characteristic in this thesis. And according to it, the dehumidify characteristic of various liquor desiccants can be calculated, analyzed and compared. And so the appropriate liquor desiccant might been chosen.A uniform mathematic model is established, which described heat transfer and mass transfer about the countercurrent flow in the dehumidifier and regenerator of the air conditioning system. And the approximately resolution for the model is deduced. An analyzing way about the perfect degree of the mass transfer in the dehumidifier is brought out by studying the running characteristic of the dehumidifier. Finally the optimized mass ratio of liquor to air is deduced on ideal dehumidify process. Some experiments about liquor concentrated has been made, which mainly discussed the influence of the temperature of heating sources and inlet air on regeneration.Finally some primary research on the characteristic of energy storage is made aiming at the system and couples energy storage in the liquor desiccant air conditioning system. The mass transfer and heat transfer during the process of storing energy was studied and based on the primary mass transfer and heat transfer model, mass transfer differential equator is solved drawing lessons from the Blasius's solving method for momentum differential equator. The amount of storing energy was calculated and discussed and made theoretic analysis on the characteristic of energy storage.
