For a room, it is better for the air conditioner to blow upwards for refrigeration, or to face downw

If it is hang-up, blow it downward, because the return air outlet is on it, which is conducive to air circulation.

If it is a cabinet machine, blow it to the top, because the return air outlet is below, and in the same way, the smoother the air circulation, the better the cooling effect.

In addition, if you need to cool down the human body quickly, blow it in the direction of the person.

PS: Principle of air convection:

Heat rises and cold falls: Hot air has a low molecular density and is lighter than cold air, so the hot air rises.

Cold air molecules are denser, and cold air is heavier than hot air, so the cold air goes down.

If the cold air of the air conditioner blows up, because the cold air density is smaller than that of room temperature, the cold air blowing up will flow down like water, so that the place where it passes will be very cool, so that the hot air will be squeezed up, so that the circulation refrigeration will be achieved, and the room temperature will be reduced.

If the cold air of the air conditioner blows downward, the cold air facing down needs to rush to the bottom, and the cold air slowly accumulates on the indoor ground, and slowly reaches the top, and the cooling speed will be slow. This method is relatively more power-intensive

In the same way, when the air conditioner is heated, the blades should be facing downwards.

It depends on the use, if you only need a local air supply, then just blow down. In this way, the air supply range is smaller, but the effect will be better. If you're sitting farther away from the air conditioner, you'll need to blow up the air conditioner to get to your range.

Generally, if the air conditioner in a large area is to make the room temperature uniform, it will be made into an air connection pipe to evenly distribute the diffusers on the ceiling. It is impossible to achieve uniform temperature distribution with hang-up and cabinet machines. So depending on your situation, generally blowing down is fine.

But be careful not to blow directly at it for too long, it is not good for the body.

According to the principle that cold air is dense and easy to sink, it should be blown upwards when cooling in summer, so that the temperature of the room is uniform. In winter, the hot air rises upwards and the wind blows downward to make the temperature even.

Blow up. The wind direction is upwards and it is cooler. When turning on the air conditioner for refrigeration, it is best to turn the air conditioner upward, because the specific gravity of cold air is larger than that of hot air, which can allow cold air to circulate from top to bottom, and also avoid cold air blowing directly on the body. When heating, let the air conditioner face downward.

Air conditioner on 26 is most suitable. This temperature can not only ensure cool and comfortable, but also suitable for staying in an air-conditioned room for a long time, and at the same time ensure that the temperature difference between indoor and outdoor is not too large to avoid colds.

Precautions for the use of air conditioners.

1. Turn on the air conditioner less when laying out the mat. Suffering from spondylosis, frozen shoulder.

People with arthritis sleep on a mattress when the indoor temperature is low, which may lead to old diseases**, gastrointestinal discomfort, and people who are afraid of catching a cold may also easily cause abdominal pain.

Diarrhea, so when sleeping on a mattress, it is best to turn on the air conditioner less.

2. The air-conditioned room is two cool and two warm. Sleeping in the air-conditioned room of Suisun should be two cool and two warm socks - "the head is cold, the back is cold, the belly is warm, and the feet are warm".

3. Turn on the air conditioner first and then close the window. When cooling and ventilating indoors, you should turn on the air conditioner first and then close the windows, and then close the doors and windows after the pollutants in the air conditioner are released when the air conditioner is turned on.

4. It consumes the most power when it is turned on and off. The correct approach is to set the air conditioner to a high cold state when the machine is turned on, so as to achieve the purpose of cooling as soon as possible, and when the temperature is suitable, change the medium and low air to reduce energy consumption.

The wind direction is upwards and it is cooler. When turning on the air conditioner for refrigeration, it is best to turn the air conditioner upward, because the specific gravity of cold air is larger than that of hot air, which can allow cold air to circulate from hundreds to down, and also avoid cold air blowing directly on the body. When heating, let the air conditioner face downward.

The temperature difference between indoor and outdoor is kept at about the same level. If the temperature difference between indoor and outdoor is too large, it is easy for people to reduce their resistance between sudden cold and sudden heat, causing air-conditioning illness with symptoms similar to that of a cold. Scientific research has found that the most comfortable temperature for the human body in summer and autumn is around 26.

Cold air is a bit heavier than warm air.

So the advice is to blow upwards and the cold air to go downwards.

When turning on the heat, it is recommended to blow down and the hot air go up.

Super blowing upwards because the cold air will sink.

Summary. Kiss <>

Hello, according to the principle of thermodynamics, cold air is heavier than hot air, so the cold air of the air conditioner should blow downward. This is because blowing downwards allows cold air to fall directly to the bottom of the room, forming a cold air mass and making the indoor air temperature more uniform. Blowing upwards will cause heat accumulation, resulting in a large temperature difference between the upper and lower levels of the room.

Therefore, the right one should be blowing downwards.

The air conditioner is blowing cold air upwards or downwards.

Hello dear <>, when using the air conditioner, you need to pay attention to the following points: 1Make good use of the energy-saving mode:

Air conditioning is an important equipment for our family to consume electricity, when using air conditioning, we should choose the energy-saving mode, and turn on the indoor and outdoor ventilation function, which can effectively save the energy of the shirt. 2.Timer power on/off:

It is recommended to turn the air conditioner on and off regularly to avoid continuous use of the air conditioner for a long time, which can not only prolong the service life, but also save the Gaoqin electricity bill. 3.Indoor and outdoor temperatures are suitable

Don't drive too low, generally set the temperature between 26 -28, too low temperature not only wastes power, but also may cause discomfort in the body. 4.Regular maintenance:

Air conditioners need to be cleaned regularly, and the external surfaces and internal filters and radiators should be cleaned, otherwise the air conditioner is prone to malfunction and will also affect the indoor air quality. 5.Stay safe:

When installing the air conditioner, it should be as far away or higher away from the body as possible to prevent children or pets from touching it by mistake, and at the same time, it should also be kept away from flammable materials when using it to prevent fire accidents.
