Diseño y construcción de un concentrador solar de tipo canal cilindro-parabólico para la cocción de alimentos

Abstract

This research analyzes the design and construction of a parabolic trough solar concentrator for cooking food, using the energy emitted by the sun daily as a source of heat. It is based on synthesizing the supporting information from scientific research sources. In the first chapter, fundamental concepts in relation to solar energy and the benefits it has with the environment are described, the different radiations and angles that affect the earth's surface, in addition, the different types of solar cookers are presented, it will also cover the advantages and disadvantages in the use of collectors.

In the second chapter, the mathematical equations that govern the design of the solar collector are detailed, as the first factor to be dealt with are the heat transfer equations, where the different phenomena such as radiation, convection and conduction generated inside are presented. and exterior of the food cooking system in the same way losses that occurs. The mathematical equation of the parabola makes it possible to find focal axes of the parabolas that make up the parabola and the efficiency they provide to the system. In the same way, the elements and dimensions that complement the equipment are described, such as: the monitoring system, glass tube (cylindrical) and the focus on the parabola where the sunlight beam falls. In the last chapter of this project, the results obtained when carrying out the tests with different foods such as canguil, corvina, eggs and heating of the water are presented, on different days between 10:00 am and 2:00 pm, since in In this period of time there is greater solar radiation, but the environmental conditions may be different, where the work of solar cooking with each of the foods could be appreciated when cooking. In the same way, a comparison is made between a parabolic dish solar cooker carried out in a previous project and the system proposed in this research, also detailing the economic analysis of the solar concentrator and the favorable benefits it would have when using the cooking system.
