Q: How to make the electric fan in the house to achieve the best results?: Place the fan on the doorway or window sill to increase the speed of air convection

Q: Where does the wind from the electric fan come from?: At the same time, the air velocity of the diagonal line must be faster than that of the straight line, causing the air pressure on both sides to vary. The air flowing along the straight line flows to the side of the air where the wind is formed

Q: Is the power consumption the same when the fan is used in different gears?: High speed gears consume more energy, but high efficiency because of large output power. Low energy consumption is slightly lower, but the efficiency is low and the heat production is serious.

Q: What is the principle of an automatic fan head swing back and forth?: The first is through the rotor shaft above the worm and the formation of supporting turbine bite, the turbine has an eccentric shaft, eccentric shaft to drive the front and back movement of the connecting rod, fan head to do the left and right swing

In the temperature stratification under the condition of the same, because the overall warmer indoor air temperature smaller, resulting in a lesser level of indoor air pressure difference outside the same distance.
