Automatização de uma bancada didática de condicionamento de ar

Abstract

The goal of this project is the automation of a didactic air conditioning stand. After evaluating the original installation, a set of thermocouple sensors and analog transducers was proposed for the 8 main system temperatures: 2 dry bulb and 2 wet bulbs of the air conditioning cycle, and 4 evaporator and condenser inlets and outlets of the refrigeration cycle; all connected to a programmable logic controller. After processing the code, this controller transmits the values to a human-machine interface, which shows the system temperatures in real time. Therefore, it was obtained a didactic stand with an interface that centralized the temperatures, instead of being read individually and dissociated from the supervisory software already installed, facilitating the teaching-learning process of the students and resulting in another benefit for the system.
