The weather is hot in summer, if you don't ventilate, the indoor air is dirty, easy to breed bacteria growth, people are uncomfortable and easy to get sick, generally open the window at 6-7 o'clock in the morning to ventilate the best.

It is easy to cause illness and seriously affect the health of the body, so it is best to open the window for ventilation in the morning.

The air in the house is not well circulated, which causes dizziness, nausea, vomiting, and some bacteria can grow; The best time to open the window is around 8:00 a.m. to 10:00 a.m.

The right way to open windows for ventilation in the summer?In summer, the temperature is high, so it is best to open the windows in the morning for ventilation, close the windows and lower the curtains before going to work, the purpose is to block the sun and heat, and maintain the indoor temperature. You can open the windows at night, but you should have a screen to keep small insects from flying in.

Ventilation begins after 9 o'clock when the sun is more abundant, and the windows can be closed before the moisture is heavier in the evening.

Open the window hot. Opening windows for ventilation is not necessarily cooler, which is related to the temperature difference between indoor and outdoor. In summer, the outdoor temperature is high, and opening the windows for ventilation not only does not bring coolness, but will be hotter, so when the outdoor temperature rises, the doors and windows should be closed in time to make the indoor temperature less affected by the outside world.

Generally, before 6 a.m. to 11 a.m., it is not too hot, and you can open the window to ventilate. After 11 o'clock, the outside temperature gradually becomes higher than the indoor temperature, so you should close the windows to block the hot air from the outside from entering the house. It lasts until 4:30 p.m., when the temperature outside is very high, and it is recommended to close the windows.

Tips for cooling down indoors in summer:

1. Clean up the room

A clean and comfortable room makes people look in a good mood, and people will not feel so hot, in fact, a clean and orderly room will mainly cause air convection, indoor air flow is fast, will take away part of the heat.

2. Pay attention to the window opening time.

Not all time periods can be opened for ventilation, in the summer during the day indoor temperature is very high, at this time open the doors and windows, the outside sunlight and heat will run into the room, the indoor temperature will rise rapidly, so try not to open the window for ventilation at noon, it is recommended to open the window for ventilation in the morning and evening.

3. Do not use indoor electrical appliances at the same time.

If the indoor electrical appliances are turned on at the same time, the heat will increase, because the electrical appliances will dissipate heat, and the radiation will also be very large, and turning on other high-power electrical appliances for a long time under the air conditioner will also lead to the long-term operation of the air conditioner, which is very power-consuming. Therefore, in the case of turning on the air conditioner, try to turn on other electrical appliances as little as possible.

4. Thermal insulation paper.

You can isolate the heat outdoors, and the simple way is to put thermal insulation paper on the glass on the doors and windows, and the thermal insulation paper can block the heat.

15-20 minutes or so.

In winter, it is generally recommended that a ventilation time of about 15-20 minutes, ventilation 15-20 minutes can basically change the indoor air, so that the indoor air becomes fresh, if the ventilation time is too long, it is easy to cause a cold or exhaust gas into the room.

Ventilation is best done by creating convection, such as opening the furthest windows and doors in the home to allow moving air to pass through the room.

In the early morning, it is not advisable to open the windows for ventilation. Most people think that getting up in the morning and opening the habitually closed doors and windows to ventilate the room can release the "turbidity" in the room and turn it into natural and fresh air, but in fact, this is not right. Opening windows early in the morning for ventilation is not good for health.

It looks pleasant to get up in the morning and open the window for air, but for people living in the city, this method is not advisable. Especially for some streets with high traffic, the lower atmosphere of the city at night is more stable than during the day, which is less conducive to the dispersion of pollutants. So the pollutant concentration is still very high around 6 a.m.

The temperature is low in the early morning and the air pressure is high. Small dust and undesirable gases in the air are squeezed close to the ground by atmospheric pressure, and it is difficult to dissipate them into the air.

If you want to sleep***, you need plenty of oxygen in the room, but the bedroom may not have as much oxygen until night, so you can open the window to ventilate. The ventilation time should not be too long, a few minutes is enough, and it will not affect everyone's sleep time. Of course, if there is a peculiar smell outside, or if the outdoor traffic line is in high traffic hours, there is no need to open the windows.

Also pay attention to the air conditions outside and do not open the windows when it rains. Open the windows on rainy days, the rain can easily splash into the room, the room will become damp, and the rain will also contain pollutants when it rains. You can open the windows after the rain because the air is a little humid after the rain and there is no dust floating around.

Frequently open windows for ventilation can effectively use sunlight and ultraviolet rays in the air, kill germs, remove harmful gases in the indoor air, and purify the air. Frequent ventilation can prevent the quilt from getting damp and prevent the growth of mites and fungi. Improve the body's immunity and reduce respiratory diseases.

It is best to ventilate once a day in the morning and once in the afternoon for half an hour at a time. But be careful, in case of haze weather, bad air quality weather, do not open the window to prevent outdoor air pollution.

In winter, it is generally recommended that the ventilation time of each window is about 15 to 20 minutes. Opening the window for ventilation for 15 to 20 minutes can basically change the indoor air and make the indoor air fresh. If the ventilation time is too long, it is easy for exhaust gas to enter the room.

If the ventilation time is too short, there is not enough fresh air in the room.

Winter is one of the four seasons of spring, summer, autumn and winter, in winter, the gas is closed, all things enter the state of recuperation and collection, and the beginning of winter is the beginning of winter.

In winter, when the cold hits, organisms reduce their life activities, many plants lose their leaves, and animals choose to hibernate, some called hibernation.

Windows are one of the building structures, including: plastic steel windows, open and fully open frameless mobile balcony windows, all-round anti-theft roller shutters, shutters, etc.
