Sistema de automação para controle de renovação de ar externo e sistema evaporativo

Abstract

This project was conceived due to the difficulty encountered in carrying out the air conditioning of environments, with the installation of equipment and air conditioning, with a pre-existing automation system in the equipment controller that provides information for the automation network, but these components do not act in the system of external air renewal, which is mandatory to maintain adequate indoor air quality in the room, with the renewal of ambient air with external air, passing through a filtering element that performs the treatment of this air, which is inserted in the airconditioned environment. The automation of the external air renewal system with evaporative system becomes very beneficial for the occupants of climate-controlled environments, who can enjoy a safer environment for their health, without the need for any operating interference. The themes of measurement instruments, PLC, programming logic, are addressed for the project in question. Although the requirements of this project can be applied to several other areas and applications. Automation benefits us in several ways, and in this project it benefits us, autonomously carrying out the renewal of air in climate-controlled environments, and controlling the operation of an evaporative air conditioning system, which improves the temperature and the thermal sensation of the environment in which it is installed, by means of sensors, actuators, and communication with the pre-existing automation network at the execution site.
