Abstract

This work aims to develop an air conditioning system for broiler sheds consist 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 by conduction and convection and then is inserted into the building. The experiment will be developed in the departments of Agricultural Engineering and Animal Morphology and Physiology, being divided into two phases: the first will set the parameters adopted in building the system, such as: physical and geometrical characteristics of the blocks, length and cross section of the mass blocks and placement of sprinklers spraying. The second phase will assess the implementation and performance of the system sheds reduced (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 buried in the ground. The first phase will be evaluated for efficiency in heat transfer in the proposed situations, through the calculation of heat fluxes and modeling system. In the second phase by the rates of thermal comfort for broilers (BGT and CTR) and water-energy efficiency of each model. (AU)
