摘要:In this research the suitability of including PCM in gypsum boards to multiply their thermal energy storage capacity is demonstrated.So the thermal storage capacity of several constructive materials is evaluated and compared, whose use and application is similar to the gypsum boards: paneling of a wall and partition wall.An experimental facility has been designed and operated for the study of the new compound material, exchanging heat with air.It has been studied the influence of different parameters and system variables (working temperature, air velocity, display of the phase change materials, and location in the building…), to establish a latent heat storage system which –complemented with passive strategies (solar gains, natural ventilation)– reduces the acclimatization energy consumption in buildings.So, here we demonstrate that a gypsum board including a 44.5% in weight of phase change materials (PCM) is able to store –in a 1.5 cm thick- 5 times the thermal energy of a current gypsum board –with the same thickness–, and the same amount to 11.5 cm brick layer, in the comfort temperature range (20-30 ºC), maintaining the mechanical and physical properties required by the regulations in force.
