24V DC Cooling Fan power save mode?

First, in the purchase of "24V DC Cooling Fan" To select the excellent quality products. Because of the fan industry technical threshold is low, uneven products on the market, so be sure to choose well-known brand products, so to ensure quality.
Secondly, since the "24V DC Cooling 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 perspective of energy conservation, the summer season Use the fan is undoubtedly the best choice. And the fan used in conjunction with air conditioning, air temperature was set at 26 ℃ ~ 28 ℃, the power and money.
Third, "24V DC Cooling Fan" own use, it is generally a big fan blades on large electric power consumption of electrical energy is also more fan power consumption is proportional to the rotational speed of the blades, such as 400 mm Fans with a time of fast-speed power consumption 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 soon stop, cool down the multi-purpose slow-speed, you can reduce the power consumption of fans. In the air flow to meet the requirements of the situation, try to use the block or slow gear.
Fourth, the use, "24V DC Cooling Fan" best placed next to the doors, windows, easy air circulation, improve the cooling effect, shorten the time and reduce power consumption.
Finally, the usual attention to the maintenance of the fan to keep its good performance, avoid fan deformation, vibration occurs, so that, to a certain extent, but also conducive to energy savings.
