Can I turn on the air conditioner in haze days? Can I breathe in haze when I turn on the air conditioner in haze days

4hw.org: winter is the season with high incidence of haze. PM2.5 index is exploding everywhere. There are many things to pay attention to in haze days, such as turning on the air conditioner, can the air conditioner be turned on in cold haze days, will the air conditioner turn on in haze days absorb haze? Let's take a look at it together!

Can I turn on the air conditioner in the haze

Air conditioning can be turned on in haze days.

Air conditioning can be turned on in haze days. Turning on the air conditioner can reduce the particles in the closed environment. The air-conditioned room is mainly to make the indoor temperature higher or lower, which has nothing to do with the air quality outside, so the air-conditioning can be turned on in the haze weather, which will not have much impact basically.

But if you want to use air conditioning to clean the indoor air is basically impossible. Because the air conditioner uses the air in the atmosphere (including haze air), it does not have the function of purification and filtration. Therefore, harmful gas cannot be filtered out. Indoor air can only be recycled, not purified. In fact, air conditioning has no great significance for this haze weather. It is probably a psychological effect. If we want to prevent respiratory tract infection, we need to ventilate the room at a proper time every day. The best time should be around 10 a.m. and 3 p.m., and we can open windows for ventilation for about 20 minutes, so that we can.

When you go out in haze weather, you should wear a mask. Because a large number of particles are suspended in the air, if inhaled by the human body, it is easy to cause respiratory diseases, and more serious will lead to chronic pharyngitis, so try to reduce the number of times you go out. This can effectively avoid the emergence of some diseases, try to maintain indoor temperature, or air quality.

Will the air conditioner absorb the haze in the haze days

Air conditioning is the circulation of indoor air, will not say haze inhalation indoor.

In fact, the general office and household air conditioners use the self circulation system, which integrates the circulation system of the air conditioner with the indoor air conditioner. The refrigeration and heating are realized by using a refrigerant called Freon through the compressor. The cold air blown out is actually the cold air drawn in the indoor air through the evaporator and then blown out by the through flow fan or centrifugal fan. In other words, the general indoor air conditioning is just to let the indoor air circulation up, does not have the function of convection with the outside air.

Therefore, turning on the air conditioner in haze days will not bring the outdoor polluted air into the house. If the air conditioner is cleaned frequently (there is no bacterial growth and ash accumulation in the air conditioner), the air conditioner will not pollute the indoor air. The quality of indoor air depends on the pollution sources (smoking, cooking, etc.) of indoor air and the airtightness of doors and windows.

How to turn on the air conditioner in haze

Reasonable temperature setting

According to the actual use of the surface, when using air conditioning in winter, the air conditioning can save more than 10% of the power when the air conditioning temperature is set to 2 ℃ lower. From the point of view of energy conservation, the lower the air conditioning set temperature is, of course, the better when it can ensure human body heating. Therefore, it is suggested that the air conditioning temperature should be set at about 20 ℃ in winter. As the warm current will go up, so we can adjust the air outlet of the air conditioner to be down, which can save electricity.

Reasonable adjustment of wind speed

When heating the air conditioner, pay attention to adjusting the air speed and wind direction of the air conditioner: when the air conditioner is just turned on, the high wind speed can be set to speed up the process of heat exchange between the room air and the air conditioner. When the temperature is close to the set temperature, the wind speed can be set to low wind speed, which can save certain electric energy. Because of the different proportion of hot and cold air, it is better to make the air conditioner wind downward to improve the exchange of hot and cold air and achieve the purpose of saving power.

Avoid frequent switching

In the use of air conditioning, avoid frequent switch air conditioning, not only does not save electricity, air conditioning in the moment of start-up will cause more electricity, and there is a certain loss of air conditioning compressor.

Do not use the air change function

Many central air conditioners also have the function of fresh air exchange. Under this function, it is necessary to exchange indoor turbid air and outdoor fresh air. However, there are filters in the air exchange, and those above PM2.5 should not enter the room. Of course, if you are not sure, you can not turn on the function of fresh air exchange of central air conditioner.

There are also some air conditioners with air exchange function, but the popularity of such air conditioners is not high. This kind of air conditioner is equipped with a built-in air exchange device. When the air is exchanged, part of the indoor return air is drawn out of the room by the air exchange device. At this time, the indoor air density drops and negative pressure (relative to the outdoor air pressure) is generated. Because there is a pressure difference between the indoor and outdoor, the outdoor air enters the room through the door and window joints to achieve the purpose of air exchange and ventilation. In haze weather, this kind of air conditioner is not recommended to turn on the air exchange function, because the convection with the outdoor air will aggravate the indoor pollution.

Regular cleaning of filter screen

In the long-term use, it is necessary to clean the filter screen in time, and this is not only conducive to the fresh and healthy indoor air, but also reduces the load of air conditioning, avoiding the generation of high power consumption. Experts pointed out that in addition to a few years of cleaning, usually the filter screen needs to be cleaned frequently, usually 2 to 3 weeks. Take out the filter screen and brush the ash with dry soft wool, or wash it with warm water below 50 ℃, and install it after it is dry. The photocatalyst in the air conditioner should also be exposed to the sun for ten minutes before use. The condenser and evaporator coil of air conditioner can be cleaned vertically by brush and vacuum cleaner.

Air conditioning can't clean air in haze

If you want to use air conditioning to clean indoor air is basically impossible. Because the air used by the air conditioner is still the air in the atmosphere (including haze air), which does not have the function of purification and filtration. Therefore, harmful gas cannot be filtered out. Indoor air can only be recycled, not purified. In fact, air conditioning has no great significance for this haze weather. It is probably a psychological effect. If we want to prevent respiratory tract infection, we need to ventilate the room at a proper time every day. The best time should be around 10 a.m. and 3 p.m., and we can open windows for ventilation for about 20 minutes, so that we can. Without windows, it is impossible to expect the air conditioner to purify the air in the house. Even if some air conditioners have the function of filtration and purification, they can only purify, and can't guarantee asepsis, virus-free, and can't release the haze. If the air conditioner is turned on to prevent haze, it is unnecessary.
