The main objective of this master thesis is the analysis of two different cold techniques
that are used in civil engineering.
First of all, the two different techniques, cooling the concrete and the ground freezing
method, will be described with all their important characteristics: manufacturing process, application of the two methods in real cases, working process, etc.
After that, it will be designed the two different vapor compression refrigeration systems that remove the heat produced for both cold technique applications in civil engineering. The design of the refrigeration system will be presented as the calculation method that is necessary to obtain all the different values that defines the two constructive solutions.
The next point that this project will study is the choice of one of these technologies and its calculation method, for doing the constructive solution’s analysis. For doing this chapter, it will be used the software proportionated for the University “Politehnica” of Bucharest, “Engineering Equations Solver”.
Finally, the last point that this project will study is the analysis of the refrigeration system if different refrigerants are used. In this last chapter it will be chosen the constructive
solution and the most advanced refrigerant and it will be studied the difference of using ecological refrigerants or the synthetics freons types. |
