Solar chimneys are among relatively modern mechanisms in the field of renewable energy which can be employed for power generation or indoor ventilation. Not many industrial prototypes of this mechanism have been implemented; however, numerous studies have been conducted to enhance the efficiency of these systems. These studies experimentally and theoretically addressed the applications of solar chimneys. In this article, experimental research on solar chimneys for ventilation is reviewed. The aim of this work is to identify parameters that have been experimentally tested so far to determine which items should be tested in the future. Each study was investigated individually due to the extent of the investigations and the difference in the environmental conditions of the tests. The difference between this review and previous studies is the focus on experimental studies. Parameters such as dimension, geometry, heat absorber materials, phase change material, hybrid systems, and installation angles were examined. The type of tested mechanism, test conditions, and studied parameters were statistically analyzed and suggestions were proposed for future research.
