Solar energy utilization for covering the heating loads of buildings is an innovative and clean way to reduce electricity consumption. A Trombe wall is a classical passive solar heating system used in buildings. Increasing the weights and volumes of Trombe walls can increase their heat storage capacities. However, this process increases a building's dead load, which is considered a problem by structural engineers. Among the alternatives for solving this problem is to use phase change materials (PCMs) for higher heat storage. This work presents a comprehensive review on the different advantages of integrating PCMs with Trombe walls. The article shows that the satisfactory heat storage capacity of PCMs can improve indoor air thermal circulation and decrease indoor air temperature fluctuations. In addition, the effectiveness of PCMs in providing protection from overheating, and improving the efficiency of the energy management process and energy saving of Trombe walls is demonstrated.

“…However, the TW's visible black matte surface makes it challenging to adhere to building aesthetic standards that restrict the TW use being Many theoretical and experimental studies for the (PV/TW) system are being done recently. Chenglong et al [5] invented a novel (PV/TW) system that utilizes the phase-change material to address the issue of the system overheating in the summer, this kind of system is referred to as PV-PCM-Trombe. The findings demonstrate data, the cooled solar panel that uses both water and air has the greatest system's daily electrical efficiency (11.69%), while when uses water only the greatest daily thermal efficiency (39.81%).…”

An experimental study was conducted to assess the impact of cooling technologies on the performance of the PV/Trombe wall system. The solar panel's cooling system included a DC fan. and the water passing through the heat exchanger installed behind the photovoltaic panel was used. The results showed that in the case of using water and air cooling, the temperature of the photovoltaic panel decreased, reaching (25.60°C) at 12 p.m. The electrical efficiency was recorded as its highest value when employing water for cooling, as it reached (13.75%). As for the thermal efficiency, it reaches its highest rate employing air and water for cooling due to the thermal energy gained by water and air, as it reached (45.83%).

“…Currently, phase change materials (PCMs) are actively studied concerning advanced thermoregulating applications due to their ability to store and release thermal energy as latent heat (enthalpy) of reversible phase transitions. 7 PCMs are considered as functional additives to construction materials, [8][9][10][11][12][13] paints, [14][15][16][17] and textiles. [18][19][20] Among others, organic PCMs have the advantages of high melting and freezing enthalpies due to their long methylene chains, a wide range of phase transition temperatures, long-term recyclability of latent heat storage, low expansion during melting, the absence of supercooling, and chemical inertness.…”
