The air in the room is not well ventilated, is it okay to close the windows and open the door and op

It's best to open the windows every day and ventilate for a while, which is more beneficial to your health. If you don't open the windows all day and keep the ventilation fan on, this kind of indoor air is not good for people's health. It would be better if there was an air filter or a fresh air system.

Mainly considering the location of the windows and exhaust fans in the room, it is best if it can form a convection effect.

Of course, it's good to open the windows.

Just open the window for exhaust air.

It is definitely better to open the window, which can maximize the indoor air circulation, remove the indoor air as soon as possible, and absorb fresh air immediately, which is conducive to physical health.

Open the window for indoor air circulation, and open the exhaust fan to improve the indoor air quality.

The exhaust fan is used to remove the air from the room, of course, the window is open, and then the window is closed after opening.

To keep the room air-circulating, it is best to open the windows and exhaust fans. This allows fresh air to enter the room while expelling the indoors from the indoors to the outside.

Opening windows can provide natural ventilation that helps bring in fresh air. Turning on the exhaust fan can increase the circulation of indoor air and help the indoor air to be discharged from the outdoors faster.

If the air in the room is not well circulated, it may lead to a decrease in indoor air quality, which can adversely affect health. Therefore, opening windows and exhaust fans is a great way to help improve indoor air quality.

If there is no environment that can allow air to circulate naturally, it is also a better solution to open the exhaust fan, normally speaking, the room should be opened every day to open the windows and doors, let the air convection for more than ten minutes, discharge the exhaust gas in the room, let the fresh air come in, which is conducive to health, but the conditions are really limited, can not open the door, can not open the window, fortunately, there are exhaust fans, all hotels are operated like this, the space is narrow, there are guests next door, it is inconvenient to open the door, The window is not a natural environment, or limited to the interior of the hotel, however, the exhaust fan is in the bathroom area, a little sound out, there is no way out!

You open the windows for a few hours to ventilate and then close the windows for exhaust.

Hello, dear, the exhaust fan can open the window when exhausting air. It must be better to open the window, which can speed up the indoor air circulation to the maximum limit, remove the indoor air as soon as possible, and absorb fresh air immediately, which is conducive to physical health. The indoor air quality of the household can be better when the window is opened, and the indoor air quality can be better when the fan is opened.

The correct way to say this is to close the doors and windows on the same side. The other side should be open.

Because the exhaust fan exhausts the air outward, the indoor air pressure decreases, so the outdoor air pressure is high, and it will run into the house.

In this way, fresh air enters the house and achieves the purpose of purifying and discharging.

If you open the window that is very close to the exhaust fan, the dirty air will be blown out, and it will come in through the window again after going around in a circle, and the ventilation effect will be greatly reduced. If the doors and windows on the other side are open, it's fine, because there's only fresh air coming in.

If all doors and windows are closed, fresh air can only come in through the cracks in the doors, and the effect will be reduced.

If your windows are well sealed, the exhaust fan is basically idling and can't be ventilated.

Windows can be opened. But the exhaust effect is very poor. It's better not to open the windows.

Whether the exhaust fan can effectively discharge the air in the bathroom is related to the air pressure difference at both ends, specifically if the pressure at the outlet end of the exhaust fan is large, the air cannot be effectively discharged, so it is necessary to keep the air outlet section of the exhaust fan unobstructed; If the air at the lower part of the air inlet is discharged due to the exhaust part, and there is no air supplement, the air is thin, causing the air pressure to become low, and it cannot be discharged, so it is necessary to keep the air flow of the lower part in time to replenish. An obvious example is that in the mahjong room or chess room of the club, many people smoke and choke, and the exhaust fan does not stop working but cannot be discharged, because the indoor air has been exhausted and the air is scarce, so there is a problem that the exhaust fan does not work but cannot be discharged.
