Implementación de un módulo didáctico para analizar el calentamiento y humidificación del aire para el LTI-ESFOT.

Abstract

The objective of this integrative project was to implement a didactic module to analyze air humidification for the course: Refrigeración y Aire acondicionado of the TSEM career at ESFOT. The humidifier of the system was determined, being the water nebulizer the best option due to its capacity to emit atomized water in a wide range, in addition to the DHT22 sensor that allowed measuring dry bulb temperature and humidity values with high precision. An acrylic duct was implemented through which the air is moved, so that the temperature and humidity values were stabilized, a fan at the beginning of the duct will oversee injecting the air into the duct. To measure the relative humidity and dry bulb temperature variables, a programming code was required, for this purpose Arduino UNO was selected, which allowed to do it in a simple and dynamic way. Functional tests were performed to determine the humidification of the air in a day, these tests were based on the data obtained in conjunction with the complementary module of this project (heating module). The time of the day that the values are measured will be influenced by the weather conditions, even so a great similarity was found in the humidification values of 30 (%) in the values of the heating section, when the temperature and humidity values were obtained, all the psychrometric properties were analyzed using the psychrometric chart of Quito.
