How long does it take to ventilate normally? How long is it appropriate to ventilate the room each d

If the temperature difference between indoor and outdoor is 15, it takes 11 minutes to open the window; If the temperature difference cannot be accurately grasped, 30 minutes of window opening is sufficient. The best time to open the window is 9:00 am to 11:00 am or 2:00 pm to 4:00 pm.

Normal people have to breathe 16 18 times per minute, carbon dioxide accounts for 4% of the exhaled air, plus the air itself contains a certain amount of carbon dioxide, if the total content of carbon dioxide in the living room reaches 5%, the human body will suffocate. Therefore, in the family with the doors and windows closed, there is a special smell in the house, which is a manifestation of insufficient oxygen in the room. Living in such an environment for a long time, the human body will show various symptoms due to the lack of oxygen, such as dizziness, headache, palpitation, fatigue, and increased blood pressure.

Opening windows for ventilation can destroy the growth environment of the seeds, so as to achieve the purpose of eliminating them. Warm, poorly lit and poorly ventilated rooms are suitable for the growth and reproduction of bacteria and viruses, thus increasing the chance of respiratory diseases in the human body. A hospital study in the United States confirmed that poor ventilation and low humidity in the living room are most conducive to the transmission of ** caused by pneumococcus A and hemolytic streptococcus.

By opening the window for ventilation, on the one hand, all kinds of amines can be discharged outdoors, and on the other hand, the concentration of acans in the unit space can be effectively reduced, and the invasiveness of acans on the human body can be reduced.

Normal ventilation is generally about half an hour, if you ask how long to ventilate after the renovation, it generally needs to be ventilated for about 2-3 months.

Normally, the indoor ventilation time can reach two hours to three hours per day, which can be determined according to the season, generally in spring and summer, we can appropriately extend the ventilation time, and because the outside environment is relatively cold in autumn and winter, it only needs to be turned on for one hour to two hours a day.

The best ventilation time is in the morning, because the environment in the morning is still relatively comfortable, and after opening the window, it can promote the circulation of fresh air, which can also play a certain role in sterilization, and in the case of good sunlight, the window can also be opened to sterilize.

If the ventilation is done well, it will take at least 2-3 months, so why take so long to move in? Because there will be a lot of formaldehyde in the house after decoration, these toxic substances will damage human health, and it is easy to cause respiratory diseases, infertility, leukemia and other diseases. Normally you can move in in 2-3 months.

Normal ventilation for half an hour is fine.

Ventilate the room for 30 minutes a day is sufficient.

Generally speaking, the ventilation time needs to be judged according to the temperature difference between indoor and outdoor and the size of the room.

1. If the temperature difference between indoor and outdoor is 20 degrees Celsius.

In the case of a room of about 80 cubic meters, the time for thorough ventilation is about 9 minutes.

2. If the temperature difference is about 15 degrees Celsius, the time required for ventilation is about 11 minutes. If you can't grasp the temperature difference correctly, open the window for ventilation for 30 minutes.

Benefits of Indoor Ventilation:

1. Purify indoor air.

The greater benefit of indoor ventilation is to purify the indoor air, which can reasonably use the sun and ultraviolet light in the air.

to kill pathogenic bacteria in the room and let the gas heat up in the room.

Convection can make the gas smell in the room more and more refreshing and light, eliminate harmful substances in indoor air quality, and then achieve the effect of clean air.

2. Improve self-immunity.

Indoor ventilation is very physical and mental health for people, which can reduce the harmful substances of indoor air quality, which in turn is beneficial to the body's respiratory system and reduces respiratory diseases.

, which in turn has the effect of improving autoimmunity.

3. Maintain the objects in the room.

Another benefit of indoor ventilation is that it can maintain the clothes, bedding sets and some items that are very prone to moisture re-regain in the room, which can make them less and less clammy and cold, and it can also reduce the probability of such objects being overgrown with insects and mold, which can greatly reduce the destruction of such objects.

What to pay attention to in indoor ventilation:

1. The selection of window ventilation time, if the temperature is not very good, rainy or hazy weather.

In this case, it is best to choose not to open the window for ventilation, otherwise it may not play the role of cleaning the air, and it may also make some dust and body moisture enter the room.

2. It is not necessary to open the window for a long time, and the long-term window ventilation is not conducive to the maintenance of the furniture, road surface, wall, etc. in the room.

The normal daily indoor ventilation time can reach two acres to three hours.

It can be determined according to the season, generally in spring and summer, you can appropriately extend the ventilation time, and because the outside environment in autumn and winter itself is relatively cold, then you only need to open it for an hour to two hours a day.

The best ventilation time is to carry the forest in the morning, because the hidden environment in the morning is still relatively comfortable, and after opening the window, you can promote the circulation of fresh air, which can also play a certain role in sterilization, and in the case of good sunlight, you can also open the window to sterilize.

Under normal circumstances, after the house is renovated, the interior must be ventilated, and the ventilation time can be maintained for about one month to three months. In addition, the specific window opening time can be from 9:00 a.m. to 11:00 a.m

From 00 to 2:00 and 4:00 in the afternoon, this time period is better, and the effect of opening the window for ventilation will be better.

If it rains, you can choose not to open the window, and the indoor air purifier can also play a role in purifying the air, and the air purifier can also absorb formaldehyde in the air.
