Diseño y simulación de un equipo didáctico para estudiar el funcionamiento real de una bomba de calor para la producción de agua caliente sanitaria : desarrollo de una herramienta informática didáctica para el estudio termodinámico de una bomba de calor para producción de agua caliente sanitaria.

Abstract

The general objective of this project was to develop a computer tool for the analysis of the thermodynamic behavior of a heat pump for heating domestic hot water for the Thermodynamics Laboratory of FIM-EPN. The methodology used was theoretical-practical. The theory of energy systems and the compression refrigeration cycle were used to determine the parameters for the analysis of the didactic system. The locations and measurement points for pressure and temperature were established, and the elements that make up the data acquisition system to be implemented in the laboratory were specified. Once the parameters and devices were established, the Python programming language was selected using the weighted ordinal criteria method. The necessary libraries were gathered to fulfill the objectives of the computer tool, such as real-time monitoring of thermodynamic variables, obtaining thermodynamic diagrams, and reading and recording data obtained from a DAQ device through pressure and temperature sensors. Finally, design requirements for the graphical interface were established following ISO 9241 standards. A software with a graphical interface was obtained, allowing for the thermodynamic analysis of a heat pump for the production of domestic hot water. The obtained programming code was in open-source software (Python), and libraries were used to read, encode, store, record, and utilize data provided by sensors in order to carry out the study of the thermodynamic behavior of a heat pump for the production of domestic hot water.
