The principle of recovery

Reasons for resurgence: the temperature rises in spring and the air humidity in the south is high. According to scientific principles and some magazines, it is formed by cold water droplets brought by warm and humid airflow.

After a winter in the south of China, the temperature of objects is low, but it rises in spring and March, but the temperature of objects (especially thick and large objects) has not risen for a while. At this time, the surface of the low-temperature object blends with the steam from the south wind from the Pacific Ocean (the south wind absorbs a lot of water vapor when passing through the Pacific Ocean), and the water vapor forms water, which is the reason for the resurgence.

Extended data

Prevent or reduce moisture regain.

1. Intermittent ventilation method: close the doors and windows facing the south, that is, the windward direction, and only open the doors and windows facing the downwind direction to reduce water vapor from entering the room. At noon, the outdoor air humidity is at the highest value, which is not suitable for opening windows. It should be adjusted in the afternoon or at night when the climate is dry. After the weather clears up, open all doors and windows to accelerate the evaporation of water.

2. Lime moisture absorption method: Lime is a good and simple adsorbent, and 1 kg quicklime can absorb about 0.3 kg of water in the air, which can be wrapped in cloth or gunny bag and placed indoors to keep the indoor air dry.

3. Indoor heating method: Make a pot of charcoal fire or put a stove in a humid room to raise the indoor temperature so that the water vapor cannot condense, thus reducing the indoor humidity.

4. Air conditioning extraction method: Air conditioning is not only used to adjust the indoor temperature, which is warm in winter and cool in summer, but also can be used as a "dryer" to prevent clothes and furniture from being damp and moldy in wet season.
