Análise de um climatizador de ar evaporativo direto utilizando o método de arranjos ortogonais de Taguchi

Abstract

One of the biggest concerns in the world is the search for better technologies combined with a good relationship with the environment. In order to contribute to this conviviality, this work proposes to study the efficiency of an evaporative air conditioner by applying the best configuration of controllable characteristics, experimenting and comparing different arrangements in order to find an optimized configuration using the Taguchi method. Three factors were tested, such as fan velocity, initial water temperature and the presence of insulation in the reservoir. The results, using the Taguchi methodology, showed that the best efficiency occurs when using the arrangement with low fan rotation, water at 16 ◦C and the reservoir without insulation, the experiments demonstrated that the best configuration uses the fan in Low spin, initial water temperature 16 ◦C, and styrofoam insulated reservoir. As a conclusion, it was observed that noise from the climatic conditions interfered strongly in the conduction of the experiments. It can also be stated that, despite the good efficiency, the evaporative air conditioning is not the best cooling equipment for the city of São Luís, since the relative humidity values were equal to or greater than 73.07 %, which is above the Recommended for thermal comfort
