The room at home is damp. What is good for dehumidification?

1. intermittent ventilation. South or southeast? That is, against the wind.

Doors and windows are closed, only the downwind doors and windows are opened to reduce water vapor entering the room. When the weather turns fine, all doors and windows can be opened to accelerate the evaporation of water. However, the outdoor air humidity is at the highest value at noon, so it is not suitable to open the window. It should be adjusted in the afternoon or at night when the climate is dry. 2. Lime moisture absorption method. Lime is a good and simple adsorbent. 1 kg quicklime can absorb about 0.3 kg of water in the air. It can be wrapped in cloth or sacks and placed in various places indoors to keep the indoor air dry. 3. Indoor heating mode. Burn 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. Pay attention to ventilation, otherwise the consequences will be serious. 4. Air conditioning pumping method. Although this move is feasible, in order to save energy, it is better to use less. 5. Electrical moisture-proof method. Color TV can always be in standby state, or you can use a hair dryer to blow out dust and moisture from the machine through the small hole at the back of the machine. It is best not to put the washing machine in places with high water vapor density such as toilets, but also to raise the position of the washing machine; Although the air conditioner has dehumidification function, it should not be turned on regularly in rainy days to keep it in good condition; Especially computers should be moisture-proof. The best way is to turn it on frequently, preferably for an hour every day to keep it dry. Computers that are not often used should also be opened and desiccant should be attached to several food bags on the inner wall. 6. You can use some moisture-proof objects to prevent moisture. For example, water-absorbing boxes, common water-absorbing products on the market, generally take calcium chloride particles as the main component, and most of them also add essence components, which can integrate dehumidification, fragrance, mildew prevention, deodorization and other functions, and are mostly used in wardrobes and shoe cabinets; The principle of moisture-absorbing bag is similar to that of moisture-absorbing box, and it is mostly used to seal the space. The content is mainly water-absorbing resin, which becomes jelly-like after water absorption and is not easy to disperse into powder. Can be widely used for moisture absorption of clothes, electrical appliances and the like, and has good effect.
