CLIMATIZADOR EVAPORATIVO DE BAIXO CUSTO

Abstract

Reducing atmospheric environmental impacts from clean and efficient technologies results in improved conditions for the well-being of living beings. The search for simple equipment and technologies are essential to reduce environmental impacts and additional energy costs for the population, especially those with low incomes. This work aimed to propose an evaporative cooling system to improve wellbeing conditions. In the premises of the Laboratory of the Vocational Educational Center, units of cones made from pottery clay were made and tested by teachers and students, supported on a 3.00 mm PVC plate, previously moistened with distilled water until verification of percolation and positioned 10 cm in front of a conventional 4-blade fan for domestic use. The apparatus was tested in a hermetically closed environment, containing a volume of 3 m3 and measured in triplicate: Temperature (oC) and Relative Air Humidity (%) with the aid of 2 thermohygrometers in the external and internal environments for comparison with the presence of clay cones, and only with the fan for a predetermined time. The ambient Revista Multidisciplinar de Educação e Meio Ambiente DOI: 10.51189/iii-coninters/10387 ISSN: 2675-813X temperature inside the hood recorded an average of 27.2 °C before the tests. The results showed that there was a slight improvement in the environment, with a decrea se in ambient temperature by 7% and the air humidity increased by 18.4% with the presence of moistened clay cones (p<0.05). As it is a prototype and temperature and humidity are relatively normal to the climate of the region, it is recommended to test with higher ambient temperatures and for a longer time, to obtain more real and substantial evaluations.
