Construcción, implementación y validación de un equipo didáctico para estudiar el funcionamiento real de una bomba de calor para la producción de agua caliente sanitaria : implementación y montaje de la estructura del banco de pruebas y montaje del sistema de almacenamiento y distribución de agua caliente sanitaria.

Abstract

The general purpose of this curricular integration work is the design, construction and assembly of a water heating equipment for sanitary use with a didactic approach. In the following sections the existing system components are evaluated prior to the development of the design, from which the design requirements that the structure of the test bench must support as a minimum for its optimal operation are obtained. With these defined operational loads, we proceed to develop a model that satisfies the operational and aesthetic needs requested by CEPUR. Based on the proposed model, a budget analysis is elaborated including the purchasing costs of the system in order to evaluate the total cost of the equipment and additionally some values that are commonly used in the development of multi-scale projects are considered. It is important to consider that the project will be developed entirely by the owner of this work and therefore the construction costs will be reduced only to the purchasing costs of raw materials and the systems that make up the equipment, which in this development are considered as standardized elements. From the results of the economic analysis and the operational prerequisites of the system, the sizing of the test bench structure was carried out, from which the selection of 2 types of structural profiles for the construction of the structure was obtained, rectangular tube 50x25x1.5 and rectangular tube 40x20x1.5, which can support the loads generated by the equipment at rest and in operation at full load. This selection was made based on calculations made on the critical member of the structure, which was obtained by simulation. Both tests were carried out with the equipment in operation at full load during a determined period of time, from which it was obtained that the stability of the equipment was not compromised under any operating condition of the equipment and that it is completely watertight as it does not present leaks or traces of humidity that could put at risk both the electrical systems and the structure itself, thus demonstrating the reliability of the equipment.
