Modificações das condições ambientais de verão, em instalações para frangos de corte.

Abstract

This experiment was carried out from February 2nd to February 28th, 1996. The objective was to evaluate the effect of the evaporative cooling systems on the improvement of chicken house thermal condition. The building was divided in four equal sectors. The treatments consisted of a ventilator and spraying system, high rotation ventilator and spraying system, spraying system, and ventilator connected to the sprayer. The globe temperature and humidity index, radiant heat load, relative air humidity were calculated. The results showed that the evaporative cooling system with a high rotation ventilator and spraying system presented the best thermal conditions for the chickens.
