Abstract
The aim of this work is to study the combined insertion effect of Phase Change Materials (PCM) and thermal insulation within a partition wall separating a conditioned room from an adjacent local which is under a periodic thermal activity. This is done by a comparative study with a reference wall under the same thermal conditions. The comparison criterion is the energy density transmitted to the local conditioned in established regime. The results show that the inclusion of thermal insulation and phase change material provides a significant reduction of energy consumption of the conditioned local; thereby a judicious choice of phase change material with thermal level and range melting temperature reduces further this reduction.
Highlights
Modern life is causing a huge problem of energy consumption
The aim of our study is to evaluate the simultaneous insertion effect of thermal insulation and phase change materials within a partition wall on the reduction of energy consumption
In the case of comfort temperature T i 20 C, we note that the phase change materials (PCM) (Tm 19 C) generates practically the same behaviour of the partition wall for all values of the melting factor and for both configurations
Summary
There are several techniques to reduce the use of air-conditioning systems and improve the energy efficiency of buildings. The last technique uses frequently phase change materials (PCM). The investigation of PCM is made for the case of conditioned local [7, 8, 9] and non-conditioned local [10]. Criteria of these works are the daily and annually energy per unit area [1, 8] or the flux density transmitted to the local [7, 11]
