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 bomba de calor y los sensores para monitoreo y registro de datos.

Abstract

In the present work, the process of implementing a heat pump in a structure to have a test bench where it is intended to study the behavior and functionality of the heat pump, which has a storage tank to simulate consumption, is described here. Data collection is carried out by installing sensors that measure physical and electrical variables such as temperature, pressure, current, and voltage, respectively, projecting them on an LCD screen connected to a PCB where all the components that translate the data from the sensors are located. The entire work is divided into 4 stages that establish a correct implementation of the equipment on the test bench. Stage 1 focuses on reviewing the operation of the heat pump when its intention is to heat water, as well as detailing the functionality of the different sensors, modules, or transducers used for data collection. In the second stage, everything related to the working parameters of the equipment is detailed. This includes the water recirculation process, which is essential for heating the water, as well as the energy requirements and the correct way to mount the different sensors within the equipment to avoid erroneous measurements, ending with initial tests to correct parameters and carrying out a second group of tests to confirm that all working parameters are being met. Stage 3 allows visualizing the results through graphs based on the data recorded with the help of the sensors. Here, the behavior of the equipment is analyzed, as well as whether it is operating under the parameters established in stage 2. Conclusions are drawn, allowing to know the possible improvements or considerations that should be taken into account to establish that the equipment as a whole does not pose a danger to the students for whom it was built. In the last stage, the bibliography used, and the most relevant annexes are presented, such as the code used to visualize the data, the database of one of the tests conducted, the schematic of the PCB, and its 3D representation.
