Temperature smart "220V Cooling Fan" can sense ambient temperature and automatically adjust fan speed, semiconductor cooling chip cooling, to regulate the function of the ambient temperature. The "220V Cooling Fan" has two stalls, high gear: when the ambient temperature is higher than the set temperature, the cooling piece of work, speed accelerated; downshifting: when the ambient temperature is below the set temperature, the coolers do not work, the speed is reduced . The fan performance, can be applied to real life. The smart "220V Cooling Fan" the biggest selling point is the "remote control", as long as there is a network, you can control the entire global home fans switch.
