How to let the electric fan blow out cold air, let the electric fan blow out the cold air

1.Sector transformation.

Prepare two empty plastic bottles first, cut off the bottom of the bottle, then drill some small holes, and then fix the plastic bottle on the back of the electric fan, with the bottle mouth facing down, then take out some ice cubes from the refrigerator, put them in the bottle, and then turn on the fan, you will feel a little cold air, and the cooling effect is very good.

After the ice melts, the water will remain in the bottle, just open the cap to let the water out, and then continue to add ice, continue to enjoy the cool cold air, and live a cool, healthy, and economical summer.

2.Use toilet water wisely.

After being bitten by mosquitoes in the summer, we all choose to apply toilet water to relieve itching. When the toilet water is applied to us, it will feel a little cool.

In the same way, we can also apply toilet water to the fan. First prepare a rag and wet it completely with toilet water, then wipe the fan with a rag dipped in toilet water. It's best to wipe the fan blades again.

Finally, when you turn on the electric fan, you will feel that the electric fan is not only cooler, but also has a pleasant smell and can also play a certain role in repelling mosquitoes.

3.Place a damp towel in front of the fan to cool down.

You can find a towel, soak it and put it in front of the fan, and then turn on the fan, and the hot air will cool down instantly. It is also possible to hang a damp towel in front of the window. As long as there is wind, the effect is the same.

Or you can use other liquids, such as diluted perfumes, toilet water, etc. Principle: When the wind blows, the air flow rate on the surface of the liquid on the towel increases, the liquid evaporates, and the liquid evaporation absorbs the heat in the air, so the temperature decreases.

Blowing with air conditioning, it is guaranteed to be cold air.

Just find a cooling source and dissipate the cold air to the fan.

1. Fan transformation

First of all, prepare two empty plastic bottles, cut off the bottom of the bottle, and then drill some small holes, then fix the plastic bottle with a cable tie on the back of the fan, the bottle mouth is facing down, then take out some ice cubes from the refrigerator, put it in the bottle, and then turn on the fan, you will feel the slightest cold wind, and the cooling effect is very good.

After the ice cubes melt, the water will remain in the bottle, twist the cap of the bottle to let the water out, and then continue to add ice cubes, continue to enjoy the cool cold air, and live a cool, healthy and economical summer.

2. Use toilet water skillfully.

After being bitten by mosquitoes in the summer, we all choose to apply toilet water to relieve itching, and when the toilet water is applied to the body, there will be a hint of coolness.

In the same way, we can also apply toilet water to the fan. First prepare a rag, completely wet it with toilet water, and then wipe the fan with a rag with toilet water, it is best to wipe the fan blades again, and finally turn on the fan You will feel that not only the wind of the fan is cooler, but the smell of the blow is also very pleasant, and it can also play a certain role in repelling mosquitoes.

3. Put a wet towel in front of the fan to cool down.

You can find a towel to soak it and put it in front of the fan, then turn on the fan, and the hot air will instantly turn into a cool breeze. It is also possible to hang a wet towel in front of the window, as long as there is wind, the effect is the same. Or you can also use other liquids, such as with diluted perfume, toilet water, etc.

Principle: When the wind blows, the air flow rate on the surface of the liquid on the towel accelerates, the liquid evaporates faster, and the liquid evaporation absorbs heat from the air, so the temperature decreases.

Make the wind blowing out of the fan coolerMethod:

1. Use plastic bottles skillfully. First prepare two plastic bottles, then cut the bottom of the plastic bottle in half with a knife, and then make several rows of small holes in the upper part to cool off later. Finally, use a rope to pass through the small round hole of the plastic bottle, fix it on the back of the fan, one on the left and one on the right, and you're done!

The point is, we put ice cubes in the bottle, turn on the fan, and you will find that the wind blowing is cooler than the air conditioner, and it is also healthy.

2. Wet rags. Wet rags can also be used to cool down, we can take a thinner cloth, water absorption should be better, and then put the cloth in ice water to soak it, and then put the cloth in front of the electric fan, so that the hot air in the wind blown by the fan will be absorbed by the water vapor, the temperature will naturally drop, and the electric fan will blow out cold air.

3. Cool water heat dissipation method. If the weather is dry and hot, mop the floor more, let the water evaporate and dissipate the heat, if the bungalow is shorter, pour some well water on the roof at noon and before the sun goes down, and the highest floor of the building (especially the flat roof) can also be done in the same way. When sleeping at home at night, you can use a bathtub, porcelain basin, etc. to hold some well water indoors, which can also help reduce the indoor temperature.

4. Cool oil. Everyone knows that applying cooling oil in summer can not only prevent mosquitoes, but also make the surface very cool. Then we can take advantage of this feature, we can apply a layer of cooling oil on the blades of the electric fan, or spray a little toilet water can also make the wind blown by the electric fan cooler, and it can also have a good anti-mosquito effect.

It also gives the whole home a refreshing scent.

1. Prepare a basin of ice water and a light towel. Soak the towel in ice water for a few minutes. Once soaked, wring the water out. Don't wring the towel too dry and don't let the towel get too wet.

2. Next, put the soaked towel on top of the metal grille of the fan. In this way, the wind can speed up the evaporation of water and absorb heat, which can make the blowing out of the wind cooler.

3. Fan refers to a tool used to generate wind and cool down on hot days. An electric fan is a device that generates airflow by using an electric drive, and the fan configured in it rotates to form a natural wind after being energized to achieve the effect of cooling.

Working principle: The main component of the electric fan is: AC motor.

Its working principle is that the energized coil rotates under force in a magnetic field. The transformed forms of energy are:

Electrical energy is mainly converted into mechanical energy, and because the coil has resistance, it is inevitable that some electrical energy will be converted into thermal energy. When the electric fan is working (assuming that there is no heat transfer between the room and the outside world), the temperature in the room will not only not decrease, but will rise. Let's take a look at the reasons for the increase in temperature:

When the electric fan is working, because there is an electric current passing through the coil of the electric fan, the wire is resistive, so it will inevitably generate heat and release heat to the outside, so the temperature will rise. But why do people feel cool? Because there is a large amount of sweat on the surface of the human body, when the electric fan works, the indoor air will flow, so it can promote the rapid evaporation of sweat, combined with the evaporation needs to absorb a lot of heat, so people will feel cool.
