How to open the window for ventilation in summer?

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

Generally, before 6:00- 1 1:00 in the morning, the weather is not too hot, so you can open the window for air. After 1 1 point, the outdoor temperature is gradually higher than the indoor temperature. At this time, the windows should be closed to prevent hot air from flowing into the house. It lasted until 4: 30 pm, during which the outdoor temperature was very high. It is recommended to close the window.

Indoor cooling skills in summer:

1, tidy the room

A clean and comfortable room makes people feel good and people won't feel so hot. In fact, the clean and orderly room is mainly air convection, and the indoor air flows quickly, which will take away some heat.

2. Pay attention to the window opening time.

It is not possible to open the window for ventilation at all times. In summer, the indoor temperature is very high during the day. At this point, open the doors and windows, the sun and heat outside will run into the room, and 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 when it is cool.

3. Don't use indoor appliances at the same time.

If the indoor appliances are turned on at the same time, the heat will increase, because the appliances will dissipate heat and radiate a lot. Turning on other high-power 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 appliances as little as possible.

4, heat insulation paper

You can isolate the heat outside. The simple way is to stick insulating paper where there is glass in doors and windows. Heat insulation paper can block heat.
