Avaliação do potencial de aquecimento/resfriamento de um sistema de climatização passiva

Abstract

The use of passive solar heating for achieving thermal comfort inside a building is a very convenient solution to reduce the cost of electricity. One of the techniques used to improve the thermal performance of buildings is using "Trombe Walls." This is a passive solar heating system that uses solar gains associated with the thermal inertia of a wall to absorb heat during cold periods without blocking their loss in the warm period. This research aims to analyze the potential for heating and cooling of a Trombe Wall. For this, two cells were built on a small scale: passive solar cell and a reference cell. The measurements took place in cold periods (dates), of 2011 and during the summer of 2012, for different configurations of the Trombe Wall. The results showed that the Trombe Wall had a positive result for both winter and summer.
