Abstract
One way to prevent accidents and reduce costs in closed environments with artificial air conditioning is through enabling technologies that continuously monitor these installations. This work aims to increase the healthiness of indoor environments and simultaneously reduce energy expenses. With the lack of established standards, collective pneumonia contamination resulted in the death of 34 people in the 80s in a hotel in Philadelphia. According to NBR - 16401-3, air renewal reduces pollutant concentrations, including CO2, aiming at equipment conservation and efficiency, as well as maintaining the minimum hygienic standard in air-conditioned environments. According to the National Program for Electric Energy Conservation, especially in its Energy Ownership and Consumption Habits Survey, the average annual electricity consumption of households (based on 2663 energy bills) is 190.12 kWh, taking into account air conditioning and refrigeration. Given this information, the authors saw an opportunity to develop this work, as healthy spaces reduce the incidence of respiratory diseases and increase the efficiency of activities performed in closed environments. To achieve the results, it was necessary to develop the code in the C language, review and test it within the test environment to collect data through two experiments: VRF system + Commercial Appliance, VRF system + Commercial Appliance (Arduino UNO Modulation). In addition, DHT11 sensors were used to collect data on humidity and temperature, MHZ-19B CO2 collector, SCT013 (current sensor), and the energy analyzer (AE200). With the equipment and programming language platforms in C and Python, the authors were able to generate graphs, where it was possible to show an 11% reduction in electricity consumption. It can be inferred that this work contributes to the establishment of the country's minimum energy efficiency standards, as well as ensuring people's thermal comfort and reducing air-transmitted diseases. In conclusion, this work demonstrates the importance of implementing continuous monitoring technologies to improve indoor air quality and reduce energy consumption in closed environments. By collecting and analyzing data through various sensors and programming languages, it was possible to achieve significant energy savings and promote a healthier indoor environment.
