Implementación de un sistema de adquisición de datos de temperatura, radiación y humedad de un panel solar de tubos al vacío para el estudio de la energía solar aprovechable en la ciudad de Riobamba.

Abstract

In order to implement a data acquisition system to do the energy study by a solar panel vacuum tubes in Riobamba, it has designed an installation for water heating ACS and the system allow to acquire the necessary data for this study based on the selection of suitable sensors and DAQ card. The hydraulic design for the installation of heating is standard NEC11 unter Chapter 14 of renewables to determine whether the solar panel supplies the heat energy needed to meet the demand of ACS for a family of four. A program developed in LabVIEW environment to record the data of temperature, radiation, humidity and flow over time and generate a report in Excel of the stored data. Fort the study of solar data was taken, the same that it was statistically with frequency distribution which determined that the contribution of solar energy occurs between 11h00 to 15h00 this being from 850 to 1150 W/m2 . Economic feasibility analysis for installing the heating system was conducted and it was found that the solar system is beneficial unsubsidized LPG recovering the initial investment in the fifth year. In the same way the project is feasible to compare the costs that have to be heated by electricity.
