“…Figure (10) shows the absorber temperature difference (Tab-SC-2 -Tab-SC-1) achieved by SC with different heat storage materials. From the figure, it can be observed that LHS material (Bitumen) increases the absorber temperature concerning conventional solar chimney SC-1 (about 15 °C between 4.0 and 6 pm).…”

“…Also, the results showed that SC is more efficient for cooling than heating purposes and the climatic conditions of the location have a slight effect on the chimney performance. Sivalakshmi et al [10] proposed an experimental investigation to study the thermal performance of a wall solar chimney integrated with a room under warm and humid conditions. Different gap widths were applied to the chimney with multiple room openings.…”

A solar chimney is a passive device that utilizes solar and wind energies for cooling, heating, and ventilation of closed spaces. In this study, an experimental investigation of the thermal performance of solar chimneys under the meteorological conditions of El-Arish, North Sinai, Egypt is presented and discussed. The experimental measurements were performed under different solar intensities, different geometric conditions, and storage heat techniques. The experimental investigation was conducted using two test rigs of the solar chimney with the same dimensions. One of them has a fixed configuration and was used as a reference, while the other one was modified at each stage of the measuring process. The experimental study was concerned with the effect of changing the gap width, integrating a layer of sensible heat storage material into the chimney, and integrating a phase change material. The experimental results showed that the solar chimneys (SCs) with gap widths of 2.5, 5, and 10 cm achieved an average daily efficiency of 21.1%, 24.1%, and 16.3% respectively. It also showed Integrating the SC with concrete and bitumen increased the air mass flow rate through the SC with a daily average value of about 24% and 32% respectively.
