Abstract: Low grade heat energies are easily available from sources such as automobiles, industrial processes, geothermal and solar energies, etc. Ejector-based air CO conditioning systems utilizing these energies offer advantages of alleviating 2 emission, O-zone friendly and more reliable. However, using the refrigerant like R134a or R141b is not zero pollution. Hence, an ejector-based air conditioning system with water as its refrigerant is proposed in this dissertation. An established model is introduced. As the most important part of the whole system, ejector modeling and implementation will be discussed at the beginning. A new method of modeling will be introduced then it will be applied into the ejector model. After ejector modeling, the model of condenser and evaporator will also be studied in the dissertation. The inner structure of ejector, condenser and evaporator will be illustrated by flowcharts. With necessary modification, it will give out the results of each parts of this system. The new database of water properly is another core of the dissertation, thus it will specify the way of creating the database and how to call it from main programs. Meanwhile, some useful website and tools will be introducedbriefly.
