All kinds of commercial public places, such as shopping malls, fitness centers, gymnasiums, stations, airports, docks, churches, etc., have relatively closed spaces, poor air circulation, long staff stay time, muggy summer, humid rainy season and turbid indoor air, which will produce a serious sense of hypoxia. Even if the central air conditioner is turned on, the indoor and outdoor air exchanges cold and heat rapidly, and the body feeling is very poor. The air conditioning effect is greatly reduced due to the too wide space, and the temperature is seriously stratified, which can not cover all areas, resulting in high costs.

There are few obstacles on the ground of commercial public buildings. It is an ideal place for large energy-saving ceiling fans to play their role. The large-scale ceiling fan brings large-area air flow, no dead corner air circulation, continuous and gentle natural breeze, solves the high temperature and muggy, eliminates the uneven temperature distribution, promotes the indoor and outdoor fresh air exchange, and creates a healthy and comfortable business environment.
