This room is not ventilated without windows. What should I do?

There is no window in the room, so forced ventilation should be considered to ensure the fresh indoor air.

1. For rooms without windows, open a hole of 100mm in the appropriate position of the external wall and install a circular exhaust fan (as shown in the figure below).

This small exhaust fan is small in size, low in noise and energy consumption, and can be used for a long time. ? If we can exhaust the air strongly all the time and replenish fresh air from the crack of the door, we can ensure the freshness of indoor air;

2. According to the actual situation, let's see if we can open a window on the exterior wall, which not only solves the lighting problem, but also ensures the indoor air circulation;

3. Cultivate some flowers indoors: chlorophytum, radish and the like, which can absorb carbon dioxide and release oxygen, and contribute to the improvement of indoor air quality.

As an unventilated indoor space, because it can't be ventilated, it will lead to humid indoor air and bacterial growth for a long time, which is not conducive to health. It takes time and financial resources to solve this problem, and ensuring good health is the key!
