Modelagem da eficiência de resfriamento (η) evaporativo em sistemas de placas porosas umedecidas.

Abstract

The goal of the present work is modeling the pad cooling efficiency (h) based on steady-state heat and mass transfer equations. As input data to model, it was used the temperature, humidity and mass flow rate of air that pass through the PAD; the temperature and mass flow rate of water that wet the PAD material; the specific area and diameter of the material used to fill the PAD and PAD dimensions. The model can be used in the determination of h of evaporative cooling systems composed by approximately spherical materials, such as the expanded clay. In addition it can provide a better understanding of the processes involved in the evaporative cooling of the air that pass through the PAD, providing insights about the system.
