A new ventilated Trombe wall (VTW) constituted with double Phase Change Material (PCM) wallboards (PCMs-VTW) has been developed. The year-round thermal performance of the system was evaluated via an experimentally validated model. The impact of the transition temperature of PCMs and air change rate on cooling and heating load were determined. Also, the total energy and the electric energy consumption of the fan were evaluated. The new PCMs-VTW can contribute to a reduction in the cooling load (14.8%) and heating load (12.7%) when fusion temperatures of PCMs in exterior and interior PCM wallboards were 26°C and 22°C, respectively. As a result, the total energy consumption was reduced, relative to the use of a shading device, by 5.83 kWh in summer and 23.54 kWh in winter. The proposed system is beneficial to indoor thermal comfort during summer and winter. The test room fitted with the PCMs-VTW has an average predicted mean vote (PMV) of 0.97 and a predicted percentage dissatisfied (PPD) of 12.5% in summer; and a PMV of –0.32 and 9.6% PPD in winter. By contrast, the test room fitted with a split-type air conditioner has a PMV of 2.71 and a PPD of 23.9% in summer and a PMV of –1.71 and 29.8% PPD in winter.

“…17–20 In the heating dominated region, Hernández-López et al. 17 evaluated the energy storage performance of a Trombe wall in two cities in the cold climate region, Mexico. They revealed that the total energy that could be stored by the Trombe wall was dependent on the outdoor weather condition.…”

“…According to the World Energy Council, primary energy demand will double by 2050 [2]. Reducing the energy consumption of buildings and improving their energy efficiency mobilizes various research studies [4][5][6][7][8][9]. Passive solar wall such as trombe wall is an effective method to increase the energy efficiency of buildings thanks to its high energy storage capacity [10][11][12][13].…”

“…For different climates, many researchers have studied the thermal performance of the Trombe wall. Herna´ndez-Lo´pez et al (2016) have presented a thermal evaluation of a room with a Trombe wall in two cities of Mexico with cold climate (Huitzilac and Toluca). They affirmed that thermal energy losses through the semitransparent wall are about 60% of the solar radiation incident on the system, which permits to keep the air inside the room with a temperature above 35°C.…”

In this article, the comparison of energy performance between a classical and an improved Trombe wall of a model test room has been carried out experimentally. The case study is conducted in Borj Cedria, Tunisia, where there is always heating requirements. Here, we propose an improved Trombe wall whose absorber wall is covered with a thin black copper panel backed rather than simply painted black wall. The proposed idea would offer improved thermal performance, especially in natural convection. The comparison shows that the improved Trombe wall design gives an increase for both conductive and convective flux. The results show that the improved Trombe wall works more effectively than the classical Trombe wall system in utilizing solar energy for the example of test room.
