Abstract

This paper extends the thermoelectric analogy method to study the thermal behavior of a concrete envelope of a dual-zone building containing microencapsulated phase-change material (PCM) and subjected to realistic climatic conditions based on weather data for a typical summer day in Tunisia. This work deals with a numerical study based on the nodal method to predict the effect of phase change on the thermal response as well as the energy flux reduction associated with the composite-envelope building. Cet article traite la méthode de l'analogie thermoélectrique pour étudier le comportement thermique de l'enveloppe en béton d'un bâtiment à deux zones contenant un matériau à changement de phase (MCP) microencapsulé et soumis à des conditions climatiques réalistes basées sur des données météorologiques pour une journée d'été typique en Tunisie. Ce travail rapporte une étude numérique basée sur la méthode nodale pour prédire l'effet du changement de phase sur la réponse thermique ainsi que sur la réduction du flux d'énergie associée au bâtiment à enveloppe composite.
