Análise computacional da distribuição de ar em recintos climatizados por métodos de estratificação de temperatura

Abstract

This work aims to perform an analysis of the flow of the conditioned air supplied in climatized rooms using temperature stratification systems, such as the displacement ventilation. The efficiency of a passive chilled beam is also evaluated as a complementary method for removing sensible heat. It is proposed to evaluate, from results obtained from computational fluid dynamics (CFD), the parameters of thermal comfort in the occupied zone and the effectiveness of these air conditioning techniques, targeting the energy reduction. A validation of the CFD code and a study of the turbulence models are also presented. These air conditioning systems have been modeled and computer simulations are carried out for different scenarios.
