The room has high humidity, do I need to open the window at night?

You need to open the window, otherwise the clothes and bedding in the room will be damp and moldy, including the wardrobe

1. Open windows for ventilation.

Ventilation allows moisture to blow outside, while dry air from outside enters the house, allowing the air inside the house to be conditioned. This greatly reduces the generation of moisture.

2. Turn on the air conditioner.

When you turn on the air conditioner, you can suck in the outside air and then exhaust it into the room through the air conditioner. Therefore, you can use an air conditioner to reduce the humidity in the house.

3. Put some items that absorb moisture.

Optional, such as activated carbon.

Something that absorbs moisture easily such as lime can remove some moisture to a certain extent. However, the effect is not particularly obvious, and it can only remove moisture in a small area, which is suitable for moisture-proof use of cabinets and wardrobes.

4. Use a wall-hung boiler.

The wall-hung boiler is more suitable for the use of the main living room of the home in winter, and the use of the wall-hung boiler can effectively reduce the moisture in the room, but it has limitations and is only suitable for use in the living room.

5. Install a dehumidifier.

The use of a dehumidifier can remove moisture from the indoor air, but the scope of removal is limited, which is very suitable for use in the bedroom and is also one of the most effective means of indoor dehumidification.

If there is a lot of humidity in the room, it is recommended that you open the windows at night to ventilate.

If you are in the south and encounter the rainy season, there is no need for the humidity outside, you can consider the air conditioner dehumidification function, or buy a dehumidifier, if you are in the north, you can open the window to ventilate and go to the humidification.

It may be due to the cracks caused by the shrinkage of the cement at the junction between the window and the outdoor cement, and the original sealingSealantFailure causes rainwater to enter the room through the cracks, causing dampness around the windows, which in turn increases the humidity in the room, resulting in too much humidity in the room.

Indoor humidity is determined by people's health, too much or too little humidity is not good for health, for the occurrence of large conditions need to pay attention, can be improved by ventilation, so that the indoor as much sunlight as possible. Be sure to observe regularly to check the humidity in the room, and if there is high humidity, it needs to be treated. There are many ways to prevent moisture and dehumidify, which can effectively improve the overall humid environment of the home.

2.Large temperature difference: there is no light, the underground layer is cold, and the temperature is much lower than the ground, so when the high temperature and high humidity air on the ground enters the basement layer, the moisture in the air is easy to condense due to the sudden drop in temperature, increasing the humidity of the underground layer.

4.Thermal insulation and drainage: foreign buildings are basically in the basement wall outside the insulation layer and drainage layer, while the domestic is almost all concrete walls, not on the outside of the insulation layer, in this case, in Zhejiang climate for example, its average wall temperature is 21, and Zhejiang's winter and summer outdoor temperature difference is far more than this.

The large temperature difference between indoor and outdoor leads to the aggravation of condensation in the basement.

Summary. Can you open the window when the humidity outside is 90%?

1. Decide according to weather conditions.

When the weather returns, if it is accompanied by outdoor rain, the air humidity is high at this time, which can reach more than 90%, try to open the doors and windows as little as possible to reduce the humid air from the outside into the room, if the indoor is not ventilated, it is also possible to turn on the air conditioning for ventilation. If it is windy outside and it is not raining, you can ventilate more in good weather to accelerate the evaporation of water vapor indoors.

2. Open the window at noon if necessary.

Do not open the windows for ventilation when the resurgence is serious, especially the south-facing house, because the warm air outside will bring humid moisture after coming in, and the indoor temperature is low, which will make the moisture in the air quickly condense into small water droplets, and the home will be more humid. If you feel that the doors and windows are closed and the indoor air cannot circulate, it is recommended that you open the windows for ventilation for a short time at noon.

3. Do you open the window to ventilate and get moisture in rainy days?

If the windows are opened on a rainy day, it will cause dampness in the house. Because the moisture in the air is relatively high on rainy days, the humidity is also relatively high at this time, if you open the window, the air will flow into the room, and the humidity of the room will also become greater at this time; And when it rains, if the air quality is not very good, the dust on the road at this time and some sediment may also enter the room with it.

Can you open the window when the humidity outside is 90%?

Please wait patiently for 3 minutes, we are sorting out, and we will answer you immediately, and please do not end the consultation.

Can you open the window when the outside humidity is 90% 1, when the weather returns to the tide according to the weather conditions, if it is accompanied by outdoor rain, the air humidity is large at this time, and it can reach more than 90%, try to open the doors and windows as little as possible to reduce the humid air from the outside into the room, if the indoor is not ventilated, it is also possible to turn on the air conditioning for ventilation. If you know that the wind outside the fruit is relatively strong and there is no rain, you can ventilate more when the weather is better to accelerate the evaporation of water vapor in the room. 2. If necessary, do not open the window for ventilation when the moisture return is serious at noon, especially the south-facing house of Zhaolian, because the warm air outside will bring humid moisture after it comes in, and the indoor temperature is low, which will make the moisture in the air quickly condense into small water droplets, and the home will be more humid.

If you feel that the doors and windows are closed and the indoor air cannot circulate, it is recommended that you open the windows for ventilation for a short time at noon. 3. Open the window for ventilation and moisture on a rainy day, if you open the window on a rainy day, it will cause dampness in the house. Because the moisture in the air is relatively high on rainy days, the humidity is also relatively high at this time, if you open the window, the air will flow into the room, and the humidity of the room will also become greater at this time; And when it rains, if the air quality is not very good, the dust on the road at this time and some sediment may also enter the room with it.

Keep warm when opening windows. It is recommended that you put on a coat before opening the window, or take a break in another room. In general, the indoor temperature is maintained at 16 -22 and the humidity is kept at 40%-60% when the window is opened, which will make the human body feel comfortable.

The window opening time is 9-11 a.m. and 2-4 p.m. is the best time. The temperature rises at these two time points, the atmospheric diffusion conditions are better, and the pollutant concentration is lower, which is suitable for opening windows for ventilation. If it is accompanied by outdoor rain, the air humidity is high at this time, which can reach more than 90%, try to open the doors and windows as little as possible to reduce the external humid air entering the room, if the room is not ventilated, it is also possible to turn on the air conditioning and ventilation.

Decide on a case-by-case basis.

1. Under normal circumstances, the rain increases during the humid weather, and the house is easy to travel "back to the moisture", if the window is opened, it is easy to increase the air humidity in the living room, resulting in moldy food, clothing, furniture and other items, people live in the humid room for a long time, which is not good for health, and if the house is wet, it is more conducive to the growth and reproduction of bacteria and viruses, so it is usually better not to open the window in humid weather.

2. However, if there is a virus in the air, ventilation will reduce the concentration of the virus formed by respiratory droplets in the air, so in this case, it is necessary to open the window for ventilation to reduce the risk of infection.

The room is damp, open the window at night or not? Well, I personally think that if the room is damp, I think it is better to open the window at night, let in the wind, let the wind blow, I think it is possible to reduce the humidity.

My personal experience is that the temperature at night is lower than during the day, not to mention the humidity, the lower the air temperature, the easier it is to make the room more humid.

If the house is damp, we are generally best ventilated during the day, there is sun during the day, and if the wind is too strong at night, it may not be good for the body.
