Paper presented at the 8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Mauritius, 11-13 July, 2011.
In many regions, it is sometimes difficult to reach
acceptable thermal comfort without continuous energy
consumption for Heating, Ventilating and Air-Conditioning
(HVAC) inside buildings. This paper describes some strategies
and some technologies to naturally improve comfort without or
with reduced air-conditioning. These strategies are based on
using Phase Change Materials (PCM) incorporated in building
structures. The PCMs used in this study are described and
characterized and a new composite material (polymer/PCM) is
proposed. Among the several types of structures that have been
studied, a brick filled with this new material has been chosen.
The responses to temperature and heat flux variations have
been studied. It is shown that the brick thermal inertia is
strongly increased and that this construction component
presents no PCM leaks.
