Parâmetros arquitetônico-ambientais para construção e testes em modelos reduzidos, representativos de galpões avícolas, com base em similitude

Abstract

Considering the importance of the use of reduced models to the study of thermal comfort on the poultry, this work had the objective to test, in a natural scale of commercial poultry building and three reduced models constructed with different scales (1:4, 1:8 and 1:12), the validity of the relations that have been proposed. Another objective of this work was finding the ideal scale to this type of experiment where the thermal comfort was evaluated using the black globe and humidity (BGHI). Based on results it can be concluded that, for the operating conditions and established design criteria, and using the BGHI as environment thermal index of farms building, it is possible to predict the thermal environment conditions in a prototype based on reduced models up to 12 times.
