Control automático de temperatura y humedad relativa del laboratorio de ensayos de ALUVIDGLASS CIA. LTDA.

Abstract

The objective of this work was the implementation of an electronic and electrical system for the automatic control of temperature and relative humidity, in order to develop quality control tests based primarily on laboratory research. For development of the system under documentary research in the field of industrial automation and quality control, the main variables were determined, temperature and relative humidity, which subsequently were monitored within a testing laboratory. The use of temperature and relative humidity sensors connected to a PLC through programmed logic, allowed the control of the actuators. The information gathered by the different sensors is displayed on an OLED screen, this data is displayed and recorded in real time, to later perform temperature and relative humidity control actions. The mechanism of action is made up of a locally controlled air cooling and heating system. For the experimental phase, the system was implemented in a testing laboratory, which is in the city of Ambato, obtaining as a result the reduction of 50% of the time that the laboratory takes to cool one degree of temperature without intervention of the system with an energy consumption of 0.746kWh., so it is concluded that the temperature and relative humidity control system is efficient in its energy consumption regarding its operation. It is recommended to incorporate artificial vision methods to identify the materials that are analyzed and thus determine temperature levels in the quality control process.
