Is it necessary to ventilate the house in wet weather?

Don't open the window for ventilation, because there is moisture in the room itself. Opening the window again to let the outside breath in will only make the room wetter, so close the doors and windows.

Modern science has proved that the suitable humidity for people is: when the temperature is 15℃ ~ 20℃, the relative humidity is 45% ~ 55%; When the temperature is 25℃, the relative humidity should be 20%. In the case of low temperature and low humidity, the body is more vulnerable to cold injury, rheumatism and bronchitis. In addition, the humid environment will also have adverse effects on patients with tuberculosis, nephropathy, rheumatoid arthritis, chronic low back pain and other diseases.

1, open the doors and windows for ventilation. This is the simplest method. Ventilation can make the water in the whole space evaporate together, but some problems should be paid attention to in ventilation. When ventilated, the weather outside must be dry, and the humidity outside is lower than indoors. Sunny afternoon is a better time, when the temperature outside is very high.

2. Desiccant and activated carbon can be used to prevent moisture and absorb moisture. There are many desiccants specially used for moisture prevention and dehumidification in supermarkets, the most common ones are moisture absorption boxes and dehumidification bags.

3. Absorb water with quicklime or bamboo charcoal. Rainy weather is not suitable for ventilation. At this time, you can put quicklime in some places in the room, which can absorb water well. Bamboo charcoal can also achieve this effect, but the speed is not as fast as quicklime, but bamboo charcoal will not disperse into powder after absorbing water, and quicklime will mature and become powder after being soaked in water.

4, air conditioning dehumidification or exhaust fan. This way of using the machine is to blow air. Just like a vacuum cleaner, it can collect moist air together, and when moisture will turn into water in many cases, this ventilation method is somewhat like ventilation.

When the indoor humidity is too high, if you don't use computers and televisions, you'd better make a protective cover to prevent the rear of electrical appliances from touching the humid air. And these appliances should be turned on more, because the heat generated when the machine is running can also effectively disperse moisture.

6, professional moisture absorption and dehumidification items. Such as absorbent, absorbent bags, etc. These articles contain some professional materials that are very effective in moisture absorption, but the cost of this method is also very high.

7. When the external humidity is high, doors and windows should be closed to prevent dampness and damp. Usually, more windows should be opened for ventilation to reduce indoor water vapor content. Especially in newly renovated houses, the humidity is particularly strong, and more ventilation is needed to eliminate the humidity.
