On the premise of not affecting the door structure, a glass door is added separately, and one door is divided into two doors. When ventilation is needed, directly open the internal glass door and use the hollowed-out wrought iron door outside to ventilate and guard against theft, so that even if the door is closed, the whole house is chilly. Some friends want to cut windows on the north wall to achieve the purpose of ventilation between the north and the south. If you want to do this, you must consider it clearly. First, look at whether the wall is a load-bearing wall, and then consider the problem of theft prevention. Maximize the proportion of balcony. For example, in some cities, the balcony area/building area is 18%, so increase the balcony area according to this ratio.
Use the pipe fan to directly punch holes in the wall to connect the pipes, and then use the fan to draw outdoor air into the room (or draw indoor air out). This practice is relatively cheap, and has little impact on the overall decoration, and a small amount of suspended ceiling can cover it. Try to replace your own window with a larger sliding window opening, and then replace the entrance door with a window with an independent switch in the middle, commonly known as the middle door. In this way, the air in the home is kept unobstructed at any time, so that the north-south airflow is transparent.
Ventilation problems do not particularly affect the comfort of living, which is much better than apartments with less sunshine. The simplest way is to even turn on the air conditioner and open the window to achieve ventilation. Open design can be adopted to reduce the obstruction of solid walls and increase the air flow in the house when conditions permit.
