Binary Ice Flow Characteristics Of Study

The binary ice thermal storage air conditioning system (BITSACS) has many remarkable merits, which has very large total heat exchanging surface and excellent pumpability, in the recent ten years, the application and research of BITSACS was a very important research direction. So it has very important significance to develop BITSACS.In my thesis, firstly, Chinese energy and electric power condition were introduced, and also introduced the merits of BITSACS and the reasons why the BITSACS has a hopeful future. Secondly, Interpreted the thermal storage theory, the fundamental of medium selection, the influence of freon to the atmosphere and the character of HCFC123 as well. Thirdly, introduced each part of the BITSACS and the circuits of the refrigeration circuit, cold-carrying circuit and the electric control circuit, discussed the equipments of every circuit and working principal. Fourthly, introduced the collection and testing of all kinds of data, for example, temperature, pressure, flux and the difference of pressure. Fifthly, introduced the different ways of producing ice slurry and the way of our experiment, also studied the fluidity of ice slurry in different IPF. Then, the fluidity of ice slurry was analyzed and we come to a conclusion at last. That is, the friction resistance of different IPF is larger than that of the water's, the difference is large when the velocity of flow is not very great, the difference was apt to stable as the velocity of flow become more and more larger. The flow resistance became larger by the increase of velocity. When the IPF increases, the flow resistance of the ice slurry became larger. The flow resistance of Ice slurry increases if the pipe's obliquity increases. That means the ice slurry that in the level pipe has the largest flow resistance, the reason is: the gravitation make the flow became more and more foul-up, accordingly, lead to the increase of flow resistance. Sixthly, introduced all of the preparative tasks before we began the experiment, because we met many problems during the test, we had our own methods which could solve these problems. In this paper, problems and these methods were introduced.Finally, pointed out the aspects which are important to the paper, we hope the researchers who study this field can do something about it that ice thermalstorage can be improved in China.
