Desarrollo de una herramienta informática para evaluación del comportamiento termodinámico de sistemas de refrigeración por compresión de vapor con refrigerantes naturales propano R-290: trabajo de integración curricular presentado como requisito para la obtención del título de Ingeniero Mecánico.

Abstract

This degree project shows a computer tool with the Python programming language, which allows monitoring the thermodynamic operation of a vapor compression refrigeration system or Split module located in the refrigerant use improvement center or CEPUR, using the natural refrigerant propane or R-290 as working fluid. The properties and diagrams ln(P)-h and Ts of the real and ideal refrigeration cycles are provided by the coding assisted by the CoolProp and Fluprodia libraries, in addition to the development of the graphical interface the Tkinter library is used for the generation of widgets and dynamic windows. The graphical interface is designed to process 8 input data, 6 of them are temperature inputted automatically from an Arduino module and 2 of them are pressure inputted manually by the user. These data are sufficient to create overlay diagrams of the refrigeration cycle and results of heat, work and COP.
