How to use ventilation fans more power & energy saving

The hot weather air conditioning, ventilation fans, no leaves ventilation fans which sre to be a lot of power . How do I use in order to save points?

First. in the time of purchase to choose a quality product. Due to the low threshold of ventilation fans industry technology, products on the market varies, so be sure to choose a well-known brand products, so to ensure the quality.

Second. since ventilation fans directly to electrical energy into kinetic energy, the power consumption is very low, the maximum power of only 60W, which is equivalent to the electricity consumed by ordinary lighting lamp, from the point of view of energy conservation, the summer season, use a ventilation fan is the best choice. While the fan with air conditioning, air temperature set at 26 ℃ ~ 28 ℃, the power-saving and money.

Third. the use of ventilation fans itself, generally a big fan of fan electrical power on electricity consumption, electricity consumption of fans and fan speed is proportional, such as 400 mm fan, fast block the power consumption of 60W, the use of slow block is only 40W, the same fans of the fastest block the slowest block of the power consumption difference of 40%, usually the first to open the fast block to cool down after use of slow gear, you can reduce the power the power consumption of ventilation fans. Air volume to meet the requirements of the case, try to use to block or slow block.

Fourth. when in use, the fan would be better placed next to the doors, windows to allow air circulation, cooling effect and shorten the duration of use, and reduce power consumption.

Usually pay attention to the maintenance of ventilation fans to maintain its good performance and avoid the fan blade deformation, vibration, etc. In this way, to some extent, but also conducive to electrical energy savings.
