Wind-catchers or wind towers are passive cooling systems, which can naturally ventilate buildings without using electrical power. They can provide thermal comfort for residents when air conditioning is required in windy regions.
In this lecture, Dr. Madjid Soltani will discuss his wind-catcher design and the study in which it was implemented.
In this study, a new design of wind-catcher is presented. The wind-catcher has a fixed column, a rotating head, an air opening with the screen, and two windows at the end of the column. The modern wind-catcher can be installed on roof-tops to take in ambient air. The wind-catcher’s head can be controlled manually or electronically in the maximum wind velocity direction. In addition, when wind velocity is low, to increase the operation of the wind-catcher, a solar chimney can be used. Natural ventilation systems that do not require electricity is a significant benefit of a wind-catcher, as it can decrease financial and environmental cost.
