wind driven cool fan

One of the most common questions regarding turbine roof ventilators, also commonly known as powerless roof or non-power roof ventilators, is why they are effective. People do not understand how or why turbine roof ventilators work or what advantages they offer. Turbine ventilation is a method of cooling a house without using electricity. When the temperature in the indoor attic is high, the ventilator will rotate accordingly, expelling the hot air from the house. If there is wind outside, it will also carry the high - temperature air out of the room as it rotates with the wind. The turbine only requires a gentle breeze or high indoor temperature to rotate, using the pressure difference to expel the hot air. The turbine rotation does not require any electrical drive at all, and it can work automatically for a long time after installation. Its working efficiency can increase attic ventilation by 15% - 50% and lower the temperature by 10 - 30 degrees Celsius. Over the course of a year, it can save approximately 15% of the cooling cost, while incurring no electricity cost itself.
