Methods of dehumidification and moistureproof in South China

Methods of dehumidification and moistureproof in South China: Close the windows in the morning and evening, use dehumidifying appliances and use desiccant.

1, close the window in the morning and evening

When wet weather strikes, always remember to close the windows at home, especially those facing south and southeast. The air humidity is higher than noon every morning and evening. If the doors and windows are not closed in time, water vapor will seriously penetrate into every corner of the house. But in this weather, you should open the window for half an hour every day, then close the doors and windows and take other measures to eliminate indoor water vapor. The most taboo is to close the doors and windows all day and turn on the air conditioner all day, which is easy to induce air-conditioning disease and make people tired and listless.

Step 2 Use dehumidification equipment

Air conditioners used in general households have the function of dehumidification. But it takes two or three hours to adjust the indoor air humidity with air conditioner, and it will make people feel very cold indoors. If you are not satisfied with the dehumidification effect of the air conditioner, you can also choose a special dehumidifier, and the effect will be faster.

Step 3 use desiccant

The most common are absorbent boxes and bags. After using it for a period of time, you can take out the substances in the absorbent box and buy bulk desiccant and put it in the box for reuse. In addition, you can use a self-made desiccant, put a proper amount of lime in a small cloth bag, tie it into a small bag and put it in every corner of the room. Lime itself can absorb moisture and reduce indoor humidity.

The principle of the phenomenon of returning to the south sky:

In spring, water will come out from the walls and floors in the southern sky, which is actually very similar to the principle of sea fog. Warm and humid ocean air flows from the warmer sea surface to the colder sea surface, and the water vapor in the air condenses into water droplets and accumulates in the air to form fog. If the temperature difference between the sea surface through which the airflow passes is large, there is a greater chance of forming fog.

Similarly, due to the cold weather in winter, the surfaces of walls and floors are getting colder and colder. If warm and humid air flows through the walls and floors at this time, the water in the air will condense into water droplets and adhere to the walls and floors, just as water seeps from the walls and floors. In summer, even if there is humid ocean airflow, the walls and floors are not cold enough inside and outside, and the walls and floors will not get out of water.
