Why can t you open the door or window when the air conditioner is turned on?

No, it will cost electricity. 1.The use of air conditioning to close the windows and doors, in order to make the use of air conditioning room form a relatively closed space, the operation of the indoor unit fan of the air conditioner makes the air in this space circulate through the indoor unit, and in the process of circulation, the refrigerant of the air conditioner absorbs the heat in the air and blows out the cool air that has lowered the temperature, due to the continuous circulation of this process, the temperature in the room continues to drop until the equilibrium point (the set temperature) The compressor stops running (the inverter air conditioning compressor reduces the speed).

2.But because this room is relatively closed, there will be some outdoor hot air into the room and the heat emitted by the people in the room and some other reasons make the temperature of the room slowly rise, when the temperature is higher than the temperature you set, the compressor will run again (inverter air conditioner is the compressor running at high speed), and then circulate the air in the room to cool down. This repetition allows the room to be controlled within the temperature range you set.

3.However, if the windows and doors of the room are open, the indoor and outdoor will form an open space, and the cold air blown out by the air conditioner will quickly absorb the heat in the air, because the window or door is open, the outdoor hot air will continue to enter the room, so as to form a large circulation, and the outdoor hot air you can not be able to cool down, so it will cause the temperature of the room using the air conditioner to drop to the temperature you set. As a result, the compressor cannot be stopped (running at high speed) and is always in working condition. 4.

The most power-consuming component of an air conditioner is the compressor, and the compressor works non-stop and is doing "reactive" work, and the electric energy consumed by it is also consumed in vain, that is, it is wasting electricity.

Turn on the air conditioner and open the window every hour to ventilate.

Usually, when the air conditioner is turned on, the doors and windows will be closed tightly to prevent the air conditioner from leaking. Over time, the indoor air will become turbid because it cannot be circulated, and because the air conditioner will reduce the humidity in the air, people are prone to symptoms such as dry and itchy throat and poor nose.

Therefore, every hour the air conditioner is turned on, the windows are opened for ventilation, and people in the air-conditioned environment should drink more water and eat more vitamin-rich fruits.

The right way to air conditioning.

The most suitable, the difference between the inside and outside temperature is too great.

The temperature difference between indoor and outdoor is kept at a constant level, and 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 sickness similar to cold symptoms. In summer and autumn, the most comfortable temperature for the human body is around 26.

2. The wind should blow upwards.

The specific gravity of cold air is greater than that of hot air, so when blowing the air conditioner, if you do not choose the swing mode, it is best to turn the fan blades upwards, that is, to send the cold air upwards, so that the air is circulated, the overall environment becomes cooler, and at the same time, the cold wind is avoided from blowing directly on the body.

The above content refers to People's Daily Online--How should the air conditioner be blown? The most important thing is to get the "posture" right.

It's like a refrigerator where you open the door of the refrigerator, and the machine keeps running to refrigerate, and it won't work. In the same way, when you open the window, the interior and exterior become one space. The air conditioner doesn't work non-stop, and you won't feel the effect of the air conditioning belt.

If you don't breathe in time for a long time, the air will not be so clean, and the carbon dioxide exhaled by floating objects and people in the room will increase correspondingly.

Therefore, after opening the air conditioner for a long time, it is necessary to open the doors and windows for ventilation, so that the indoor air can communicate with the outdoor air, so as to achieve the purpose of indoor and outdoor ventilation.

There was once a case of a group of people who were indoors for a long time without opening the doors and windows, and finally fainted.

High-purity carbon dioxide is mainly used in the electronics industry, medical research and clinical diagnosis, carbon dioxide lasers, calibration gas for testing instruments and the preparation of other special mixed gases, and is used as a regulator in polyethylene polymerization reactions.

Solid carbon dioxide is widely used in refrigerated dairy products, meat, frozen foods and other perishable foods in transit, and as a refrigerant in many industrial processes, such as crushing heat-sensitive materials, rubber polishing, metal cold treatment, shrink assembly of mechanical parts, vacuum cold traps, etc.

Turning on the air conditioner without opening the window can easily cause microorganisms such as dust and bacteria remaining in the air conditioner filter to permeate the room, affecting the indoor air quality and not being conducive to health. Opening the air conditioner without opening the window makes the indoor air not circulated, easy to feel stuffy, and can not maintain indoor humidity, resulting in dryness.

In fact, after the air conditioner is just started, the wind blowing out will be mixed with some dust, because there will be a certain amount of dust accumulation at the air outlet of the air conditioner, and the doors and windows will be closed all the time for the emission of these dust.

If the windows are kept closed, the dust will always accumulate in the room, and for people in this environment, long-term inhalation of such dusty air is also quite harmful to the person himself.

Notes:

After the air conditioner is activated, it also takes time for the air to be replaced and discharged. If the air conditioner is turned on and the windows are opened for ventilation for a long time, the consumption of the air conditioner will be increased, and the electricity consumption will be increased, and the actual cooling or heating effect will not be achieved.

It is recommended to open the windows for ventilation every 2-3 hours when using the air conditioner. When you fall asleep at night, you can leave small narrow gaps in the doors and windows to cool down and properly regulate the air in the room.

Summary. You can adjust the temperature of the air conditioner to the lowest level and feel the coolness, and then you can adjust it to 27 degrees.

Hello. How many degrees is the most appropriate to turn on the air conditioner at night.

You can open the windows when you turn on the air conditioner. Turning on the air conditioner will dry out the indoor air, and because the air is not circulating, the environment will not be improved, and it is easy to make people have nasal congestion, dry throat, sneezing, etc. Therefore, it is recommended to open the window once every 1 hour or so, about 15 minutes each time.

Especially for some people suffering from respiratory diseases, the time to turn on the air conditioner should be as short as possible.

Air conditioning is most suitable for 27 degrees.

You can adjust the temperature of the air conditioner to the lowest level and feel the coolness, and then you can adjust it to 27 degrees.

It is best not to blow at the air conditioner at night.

Well, turn on the air conditioner at night and the wind speed is two levels, sleep, 28 degrees, is it okay to run like this.

OK. Good.

Are the windows open a little cracked?

Just open some gaps for ventilation.

When you first start the air conditioner, you need to open the doors and windows, and wait for the air conditioner to cool down for about 5 to 10 minutes, and then close the doors and windows, mainly to ensure that the polluted air in the room is discharged to the outside, which is also the healthiest practice.

Under normal circumstances, after the air conditioner is turned on for up to 3 hours, the air quality in the room will not be very good, if it exceeds 5 hours, the indoor air can only be said to meet the standard of serious pollution, our doors and windows are closed, we stay in such an environment for a long time, it is not good for the body. Therefore, it is necessary to open the windows every few hours for ventilation.
