DC Axial Fan power law

First, in the purchase of "DC Axial Fan" To select excellent quality products. Since the fan industry technology low, uneven product on the market, so be sure to choose well-known brand products, so to ensure quality.
Secondly, since the "DC Axial Fan" can directly convert electrical energy into kinetic energy, the power consumption is very low, the maximum power is only 60W, equivalent to the consumption of the general lighting of the lamp power, so from the point of view of energy conservation, the use of the summer season fan is undoubtedly the best choice. And the fans used in conjunction with air conditioning, air temperature was set at 26 ℃ ~ 28 ℃, the power and money.
Third, the use of the fan itself, the general large fan blades on large electric power consumption of electrical energy is also more fan speed is proportional to the power consumption of the blades. Such as 400 mm of fans, with a quick stop when the power consumption of 60W, using a slow-speed, only 40W, the same fans of the fastest and slowest block retaining power consumption difference of 40%, therefore, usually the first to open fast gear, after a slow cool down multi-block, you can reduce the power consumption of fans. In the air volume to meet the requirements of the situation, try to use the block or slow gear.
Fourth, when using, "DC Axial Fan" best placed next to doors, windows, easy air circulation, improve the cooling effect, shorten the time and reduce power consumption.
Finally, the maintenance of the fan usually pay attention to maintain its good performance and to avoid blade distortion, vibration occurs, so that, to a certain extent, is also conducive to power savings.
