    It is very beneficial to open the window for ventilation in daily life, first of all, you can increase the oxygen in the room, if the window is closed for a long time, then the room is in a closed space, and the human body will release some carbon dioxide.

    In addition, it can also maintain a fresh state of air, in such a case, it can also reduce the occurrence of diseases, and long-term unventilated rooms are prone to produce some dust and bacteria, opening windows to ventilate can help kill bacteria in the air, and can also accelerate the spread of dust. <>

    Air quality. Don't open the window for ventilationSome netizens have a wrong perception of the air, they think that the indoor and outdoor air quality is about the same, even in the case of haze, so many people will choose to open windows for ventilation if the air quality is not very good, but in fact, this statement is wrongThrough some research, we can also understand that the indoor air is compared with the outside air, if the outdoor air quality is very poor, then the indoor air will be better, and if the window is opened, some outdoor particles with high concentrations will enter the indoor air of the home audio room, and then it will threaten the health of the human body, so if the outdoor air quality is very poor, do not open the window for ventilation. <>

    If the air quality is relatively poor, and you still choose to open the window for ventilation, it will cause some harm to the human body, such as haze weather.

    If you choose to open the window, there will be some particulate matter into the room, and then breathing to the lungs will have a negative effect on the lungs, of course, you can also choose some air purification devices, in such a situation will greatly improve the quality of indoor air. <>

    At present, the air quality in many cities is not very good, and there is no good effect when the windows are opened for ventilation, so many netizens will choose to install a fresh air system in their homes.

    Then bring some fresh air to the home.

    Under the premise that the outdoor air quality is not good, opening the window for ventilation may bring in various pollutants outside, which will aggravate the indoor air pollution degree and easily cause health hazards to the human body, so it is best not to open the window for ventilation.

    If you want to keep the indoor air fresh and clean without opening the windows, you can choose to use an air purifier to completely purify and renovate the indoor air.

    Different air purifiers have their own purification technology, and they have their own advantages for indoor air purification. As one of them, the low pressure negative ion generation technology can continuously and stably release small particle size negative oxygen ions, forming a spherical "negative oxygen ion field" in the room, which actively combines with positively charged dust, pollen, bacteria and other particles, and settles down to achieve the effect of sterilization and dust removal; At the same time, negative oxygen ions themselves have a strong redox effect, which can destroy the cell membrane potential and virus structure of bacteria, inhibit the growth and reproduction of bacteria and viruses, and thus reduce the content of pollutants in indoor air.

    To be, in general, indoorAir quality. The air quality will be worse than the outside, and even on smog days, such heavy pollution needs to be kept ventilated.

    But in the case of heavy pollution, there is no need for large doors and windows. For this reason, it is possible to open the window even when the air is heavily polluted, but it is necessary to pay attention to the specific time of opening the window. Generally speaking, the time when the windows can be opened for ventilation with heavy air pollution should be set around 10:30 a.m. to 11 a.m. and 2 p.m. to 3 p.m., and air purifier equipment should be placed at home as much as possible.

    Precautions: Under normal circumstances, the indoor environment will be worse than the outdoor environment, so it is necessary to maintain a certain amount of ventilation. The indoor environment is better than the outdoor environment, and the gap between the windows and ventilation in such a room should be smaller.

    If the floor is low, or close to a traffic artery or a restaurant or other business, the outdoor environment is worse than the indoor environment, and the gap between the windows and ventilation should be larger.

    1. It is not good to open the window all the time for ventilation.

    The air quality is different at different times of the day, although the windows should be opened every day for ventilation in order to maintain a fresh space and improve the air quality in the house. But between 9-11 a.m. and 2-4 p.m., the air quality during these two time periods is relatively good, and it is recommended to open the windows. The rest of the time, because of the traffic jam, a lot of exhaust fumes will be generated, if the windows are opened for ventilation.

    The air quality is not very good, if the haze weather, the outside air quality is worse, in this case, the window will lead to a worse indoor environment, in this case, it is not recommended to open the window for ventilation.

    2. Generally, the time for opening the window for ventilation is 20-30 minutes.

    In the case of a small room, windy outdoors or colder weather, it is recommended to keep the banquet room short when opening the window to prevent cold; If the room is large, there is no wind or warm air outside, the window opening time can be appropriately extended. For example, in an 80-square-meter room, it is enough to open the window for about 20 minutes without wind or breeze.

    3. The window has a certain ventilation effect by opening a small gap, but the effect is not very good, and it can not achieve the effect of ventilation, if you want to fully ventilate, you generally need to form convection in the room, but for the room with heating or air conditioning, you only need to open a small gap to ventilate, open a larger part will let the heating lose, and the indoor temperature is very chaotic and easy to drop, which is not conducive to heating.

    4. When opening windows for ventilation, the convection of doors and windows is better.

    Under normal circumstances, when the window is opened without convection, although the ventilation has a certain effect, the efficiency of ventilation is not as good as the window convection, it is recommended to open some doors and windows as much as possible when ventilating, only the air is convection, the effect of opening the window and ventilation is the best.

    Although most citizens have the habit of waking up early in the morning and opening windows to ventilate, early morning ventilation may not be appropriate in the context of modern industrial pollution and increased vehicle exhaust.

    First, there are two peaks in urban air pollution day and night, and there are also two relatively clean troughs. The two peaks are generally around sunrise and in the evening, and the two relatively clean periods are around 10 a.m. and 3 p.m. Therefore, the public can choose the window opening time according to the actual situation in the area, and it is best to avoid the two pollution peaks in the morning and evening, which is one of them.

    Second, don't open the door all day long, experts believe that 3 to 4 times a day, 30 minutes at a time is enough. In a space of 100 cubic meters, for example, when there is no wind and the temperature difference between indoor and outdoor is 20, it takes about 11 minutes to exchange air. The frequency of ventilation can be decided according to your psychological needs, and for office workers, it is enough to maintain ventilation during the period at home.

    Third, it is not advisable to open more windows on cloudy days, and the choice of ventilation is also different under different climatic conditions. Pollutants are cleaned in rainy and snowy days, and pollutants are easy to dissipate when the wind blows, and the air quality in this weather is higher, so citizens can open more windows appropriately. However, on a cloudy day with very low air pressure, the temperature inversion from the ground does not disappear for a long time, and it is difficult for pollutants to dissipate, and even photochemical smog occurs, so it is not appropriate to open windows and go outdoors.

    Opening windows for ventilation is our common sense, which can enhance the quality of our indoor air and promote the timely discharge of harmful gases in the room. Not opening windows for ventilation can lead to a series of environmental problems such as poor indoor airflow, which affects our health.

    1.As a result, the indoor harmful gases increase, the carbon dioxide content increases, the harmful gases produced by smoking cannot be discharged in time, and the indoor air is turbid. Human breathing will produce carbon dioxide, our normal breathing inhalation is oxygen emitted carbon oxide, and then there are a certain amount of impurities and trace amounts in the body, noble gases, so indoor air will be affected by carbon dioxide.

    And many people have the habit of smoking at home, smoking, and then not paying attention to open the window for ventilation will lead to indoor carbon dioxide and Wei Chenliang more than 10 times taller than usual, air mobility is very poor, and then it will lead to the appearance of third-hand smoke, that is, second-hand smoke, which is not completely absorbed, and then some smoke falls on the clothes sofa, resulting in third-hand smoke, which will also have continuous harm to our body, smoke will linger indoors, for several days, although you may not smell the smell of smoke, but the smoke really has always existed.

    2.Accumulation of harmful gases in the room, such as some formaldehyde from home decoration. This can greatly affect the air quality in our city, and formaldehyde is a harmful gas.

    It will affect our indoor breathing, the more air we inhale, or the more cubes, the more serious the pollution by this chemical will be, and it is easy to get some lung diseases in the body for a long time, or the inducing tendency of cancer, because it is a heavy metal harmful gas, which is very bad for the body.

    Feel the influence of the weather in the north, it is indeed inconvenient to open the window for ventilation in winter, the weather is very cold, and then when the window is opened, the indoor temperature will be greatly reduced, and it will be difficult for the elderly and children to bear. Therefore, a new ventilation method has been developed, that is to say, according to the fresh air system, it uses the positive and negative pressure of the air to achieve a state of indoor air flow circulation, and then it will not lose a lot of heat around us, and it can play a ventilation effect, which is a good indoor tool.
