Abstract

In the present work we presents 2D numerical study of using a phase change material to improve thermal performance of building in Tlemcen (north of Algeria) for typical day chosen with known outdoor temperature, solar radiation and wind velocity. A specific paraffin material was placed in brick wall to reduce the room temperature during a daytime. The numerical approach uses effective heat capacity Ceff model with realistic outdoor climatic conditions of Tlemcen city, Algeria. The numerical results show a significant temperature reduction inside the studied solar test room, about 6°C to 8°C and therefore, the energy consumption due to air conditioning is reduced which provides benefits to economic and environmental aspects.
