This work aims to develop an air conditioning system for broiler sheds through a process diathermic, consisting of ceramic blocks buried in the ground. The air spray will suffer and go through the exhaust system sucked (negative pressure) in a heat exchange with the environment and then is inserted into the zootechnical construction. The experiment will be developed jointly by the departments of Agricultural Engineering and Animal Morphology and Physiology, being divided into two phases: first, the parameters are set to be adopted in building the system, such as length and cross section of the mass of blocks, positioning sprinkler fogging and relative humidity increased by the system. The second phase will assess the implementation and performance of the system in model broiler sheds (scale 1:5), with the same proportions of a real barn. The study will be used two models with dimensions 30.0 m long, 2.80 m wide and 0.56 m high, built with the same materials and ventilation tunnel type, and a system with evaporative cooling of air and the other coupled to the system with ceramic blocks underground. Evaluation will be conducted through the thermal comfort index for broilers (BGT and CTR), water-energy efficiency of each model and air quality.
