A prototype for automated management of air conditioning in the hospital

A large part of electricity consumption in hospitals is spent on air conditioning equipment. This is due to the fact most equipment is old and has low energy efficiency. In addition, in some places there are no rules of use the air conditioning and it can be used at temperatures that do not generate thermal comfort for patients, also causing greater energy consumption. The present work develops a non-invasive system for control and automation of conciliated air, seeking energy efficiency and low cost of implementation, combined with sustainability and thermal comfort. Using the same infrared communication principle as conventional remote controls, a drive module with a Wi-Fi connection was developed, connected to a database that contains the equipment information. The activation and control can be done remotely. The drive module is composed of a power supply, an IR LED and a microcontroller with Wi-Fi connection. The database used is PostgreSQL and to perform the communication between these two systems, a web page was created with login and password, where the user can start the equipment and also configure operating hours so that they work autonomously. Until now, tests have been carried out on air conditioning units in the split model, commanding them remotely, showing that the system is capable of accomplishing its purpose. Future studies will evaluate if this systems will reduce the energy costs.
