Study of the air temperature reduction potential through the evaporative cooling system in the region of Maringá-PR Brazil

Abstract

The present work objective was to determine the air temperature reducing potential through the use of evaporative cooling systems for the Maringá-PR region using 13 years data from Maringá Meteorological Station. Temperature reducing potential through evaporative systems was related to the environmental temperature and relative humidity. Results pointed out that the months that the which presented the best potential of temperature reduction were August, September, October and November, due to the low values of relative humidity. The months of December, January, February and March presented lower potential of temperature reduction through evaporative cooling systems due to the incidence of larger values of relative humidity despite taking place in the summer. However, by the analyzed values, it was concluded that this technique (evaporative cooling) is promising to the most critical hours (13h00min to 18h00min), which presents the highest air temperature
