Diseño y construcción de un equipo para la obtención de agua potable por medio de la condensación de la humedad del aire : Diseño y construcción del evaporador y válvula de expansión.

Abstract

The main objective of this curricular integration work is the design and construction of an evaporator and an expansion valve to obtain drinking water by condensing the humidity in the air. Several specific objectives have been set to guide the development of the project and to ensure that the main objective is met. The main variables and parameters necessary for the design of the evaporator and expansion valve were established. This step was important to understand the technical and operational requirements of the evaporation and condensation process. Subsequently, a mathematical model describing the sizing of the evaporator for the prototype was developed. Sizing and selection of suitable materials were performed to ensure the efficiency and durability of the prototype. Detailed drawings were prepared for the fabrication of the equipment, ensuring an accurate design that meets quality and safety standards. The construction of the prototype components was carried out in accordance with these drawings and specifications, following proper assembly and mounting procedures. A testing protocol was established to evaluate the correct operation of the prototype. The tests included the evaluation of parameters such as water extraction capacity and condensation efficiency, ensuring that the equipment performed as expected. The performance of the equipment was evaluated by comparing the results obtained with the expected theoretical values. Finally, conclusions were drawn and recommendations were provided based on all the activities performed during the design and construction of the prototype. These recommendations include the installation of the prototype in clear environments to maximize water production due to the increase in relative humidity and the suggestion to use an autonomous photovoltaic system to ensure its operation without depending on the electrical grid.
