SUMMARY:

The present work aimed to analyze the performance of Split inverter type air conditioners in relation to conventional Split type equipment, considering a hypothetical scenario for a residential building of social interest (HlS), in hot and humid climate. In this way, an existing building located in the city of Jacarepaguá, Rio de Janeiro was selected as a reference. Thermoenergetic simulations, using the program ©EnergyPlus and the application, Open Studio, were used to obtain output data, indispensable for comparative analyses. For that, a reference model of the selected real building was elaborated from the procedures established in the simulation method of the Technical Quality Regulation for the energy efficiency level (RTQ-R, 2012). The method also considered patterns of use and occupation. As a result, the energy model of the building was obtained and, at the same time, data on the constructive components, the pattern of use and occupation, the energy loads of the artificial lighting system, electrical equipment, air conditioning and respective curves were entered. of performance, as provided by suppliers, as well as information on air infiltration, as provided for in standard NBR 16555-3 (2018). However, it was possible to estimate the thermal load of the air conditioning equipment and, consequently, the energy performance was analyzed through the monthly electric energy consumption and the simulated annual EER of these equipments. Through the simulation it was possible to verify the difference in the operational performance of the conditioners compared in addition to the factors that influence energy consumption, with regard to climatic conditions. In this way, the hypothetical replacement of fixed Split by Split inverter devices, allowed a reduction of up to 41% in annual electricity consumption, as well as an increase in energy efficiency, by reaching values above 30%, comparing the two types of conditioners. . The results obtained in this research also show that the option to use inverter-type conditioners would reduce operating consumption considerably, providing a minimum savings of R$ 3,000.00 regardless of the housing analyzed, thus making it an attractive choice in the long term.
