First, "220V AC Cooling Fan" in the purchase of excellent quality products to choose. Since the fan industry and technology low, uneven products on the market, so be sure to choose well-known brand products, so to ensure quality. Secondly, because the fan can directly convert electrical energy into kinetic energy, power consumption is very low, the maximum power is only 60W, equivalent to an ordinary desk lamp lighting the consumption of electricity, so from the point of view of energy conservation, the use of the summer season is undoubtedly the most fan Good choice. And the fan used in conjunction with air conditioning, air-conditioning temperature set at 26℃ -28℃, the power and money. Thirdly, the use of the fan itself, the general large fan blades on large electric power consumption of electrical energy is also more speed is proportional to "220V AC Cooling Fan" and fan power consumption, such as 400 mm fan with a quick stop when the power consumption of 60W, use slow-speed, only 40W, the same fans of the fastest and the slowest block retaining power consumption difference of 40%, therefore, usually the first to open fast stop, cool down the multi-purpose slow block, you can reduce the power consumption of fans. "220V AC Cooling Fan" at the amount of wind to meet the requirements of the situation, try to use the block or slow gear.
