Experimental and simulation analysis on the thermal performance of solar thermal curtain wall as building envelope
The need for environmentally friendly and energy efficient building design has stimulated the organically integrating buildings with energy systems,especially solar collectors.This paper investigated the thermal performance of a solar curtain wall system integrated in a house and special attention was paid to the thermal performance of solar curtain wall.A model was built and experimental data was collected to study the solar curtain wall.The results showed that in typical summer day,the cooling load is 1.822MJ/m2·day,while in typical winter day,it can contribute heating for 0.138 MJ/m2 ·day to the building.A sensitivity analysis was made to investigate variations on the heat transmission of the solar curtain wall.The results showed that the cooling load could be reduced by about 39%when the insulation thickness was increased from 25mm to 50mm.A comparison of the solar curtain wall,the traditional wall and the solar curtain collector integrated with traditional wall was made.Compared with the traditional walls,the heating load of the fa?ade-integrated walls was less and the walls even contributed heating for the building.Though the cooling load was increased,the comprehensive performance of the fa?ade-integrated walls was superior to the traditional walls.
