“…Omara and Abuelnuor [54] reviewed the implementation of Tromb walls with PCMs. The review led the authors to conclude that the low-thermal resistance of the tromb wall could be mitigated through the incorporation of PCM, which exhibit high storage capacity, and hence the heat dissipation can be reduce and solar radiation gain could be better controlled.…”

The consumption of energy for cooling is an important issue, especially in subtropical climates where there are high temperatures and dry weather in the summer; this climate forces homeowners to use mechanical-electric cooling and ventilation. The main advantage of passive cooling is to minimize energy demands which are required to achieve thermal comfort in buildings, especially with climates exhibiting high ambient temperatures. This paper presents a detailed literature review and concept breakdown for passive cooling and ventilation in building by offering the fundamental principles of the techniques of passive cooling and ventilation. Moreover, the status of passive cooling developments along with state-of-the-art research is critically reviewed in this paper. Furthermore, the article focuses on Buoyancy air-driven ventilation. Solar control techniques are explained and classified along with techniques for heat modification and dissipation. This paper offers insight into the design considerations of different passive ventilation systems and presents recommendations for future work to achieve cost-efficient, comfortable living. Moreover, novel systems are reviewed and discussed to better understand the role of Phase Change Material (PCM) in passive cooling systems.

“…One of the most common reasons that PV modules are ventilated through backside air gaps is the cooling of the PV cells, which improves their efficiency. The effect of cooling can be further increased by decreasing the overheating of PV cells by storing the heat in the phase change material [25,26], However, in the analyzed case, the BIPV in the form of a glazed façade, structures are built with relatively thick (4 to 5 mm) double-sided hard glass layers, using material with a relatively low thermal conductivity (g 0.76 W/mK). In addition, the PCM material has even lower thermal conductivity at 0.2 W/mK.…”

“…Commonly, researchers report that cooling with latent heat storage improves the annual electricity production with PV and that such measures are also cost effective [25]. A literature review [26] reveals that PCM heat storage is most often placed on the backside of a BIPV. Indartono et al [27] used a 15 mm PCM layer with a PCM melting temperature range of 42-55°C on the backside of a PV module.…”

“…From results, solar dual catalytic Trombe wall with traditional shapes of inlet and outlet showed a decrease in thermal efficiency with increasing channel width while there was no noticeable effect with the channel height. Omara and Abuelnuor [12] presented an extensive review on the various advantages of using PCMs Trombe walls. The article showed that heat storage capacity was adequate because PCM can…”

Using solar energy to cover heating loads of building is a clean and unconventional way that can help reduce electricity consumption. Problems of the cost of energy and environmental pollution are among the most important challenges facing humanity at the present time. And as most of the energy is used for heating and ventilation, thus the need to find renewable sources of energy has become a pressing need. In this direction Trombe wall, which is a classical passive solar wall, has become one of the most important heating and ventilation technologies of buildings. In the present work a three-dimensional numerical study of thermal energy performance for Trombe wall utilizing paraffin wax as PCM was presented. The effect of PCM thickness was studied as (2, 3, 4 and 5 cm). A FORTRAN-90 computer program was built to solve a three-dimensional, turbulent Navier stokes and energy equations in addition to enthalpy transforming method for PCM with explicit scheme based on finite volume method. Numerical results of the present code were validated by comparing them with previous experimental results and a good agreement was noted. The results show that a 2 cm thick PCM is an optimal thickness, where the percentage rates of increasing in air temperature over ambient temperature at day hours (10 am, 12 pm, 5 pm, 10 pm and 7 am of the next day) were (37.8, 19.5, 30.7, 60 and 69.2%) respectively, compared to (33.5, 15.2, 25.9, 53.3 and 65.3) % respectively for a 5 cm wax calculated at the same hours.
