THREE METHODS TO EVALUATE THE USE OF EVAPORATIVE COOLING FOR HUMAN THERMAL COMFORT
Abstract
This paper presents three methods that can be used as reference for efficient
use of evaporative cooling systems, applying it, latter, to several Brazilian
cities, characterized by different climates. Initially it presents the basic
principles of direct and indirect evaporative cooling and defines the
effectiveness of the systems. Afterwards, it presents three methods that
allows to determinate where the systems are more efficient. It concludes
that evaporative cooling systems have a very large potential to propitiate
thermal comfort and can still be used as an alternative to conventional
systems in regions where the design wet bulb temperature is under 24ºC.
