Latent heat storage is an economical way to achieve energy
efficiency and improve thermal comfort in buildings.
In this research, the effects of using PCM Wallboards in a
residential apartment envelop located in Homs was studied by PCM
Express so
ftware.
PCM wallboard with 23°C melting temperature was used and
installed on the inner face of the walls and ceiling of the apartment.
This investigation shows that the importance of using PCMs in
buildings envelope, compared with conventional thermal insulation
materials, due to the effectiveness of PCMs materials and storing
and releasing of thermal energy, which contributed to reducing of
thermal loads and improved the internal thermal comfort.
In this paper, an analytical and mathematical study of the PCM
wallboards was done by simulate its thermal behavior, depending on
governing heat transfer equations which describe the phase change
process of the PCM wallboard . A mathematical model
was done
and used to simulate the thermal behavior of several different
structures of the wall (single PCM wallboard, PCM wallboard +
thermal insulation layer, PCM wallboard + a concrete block).
Thermal energy can be stored as a latent heat in building structures
by materials with low phase change temperature called phase
change materials (PCM).
In this paper, an analytical and mathematical study of the PCM
wallboards was done by simulat
e its thermal behavior, depending on
