Interaction Between Walls and Roofs in Non Air Conditioned Rooms.
Abstract
In this work we present evidence of the interaction in the heat transfer through the buildings envelope components when not using air conditioning. A comparison between a test cell analysis and a single component analysis is carried out for two different constructive systems considering an air-conditioned room and a non air-conditioned one. For an air-conditioned room, the results the results of both analysis are almost identical. For a non air-conditioned room, the results from these analysis are different because the heat transfer through an envelope component is affected by the heat transfer to the indoor air by other components. This is not the case for the air-conditioned room where the indoor air temperature is kept constant.
