What is physicochemical dehumidification?

Physical chemistry is a discipline that combines physics and chemistry to study the reasons for the change in the nature of matter. Because in the process of material change, physical factors and chemical changes are mutually influencing. Here's a simple example:

When beer is poured into the cup, it creates a large number of bubbles, which are carbon dioxide dissolved in beer.

precipitation. For a single bubble, where in the cup, when, and how does the bubble start from a carbon dioxide molecule to form a bubble? What factors affect the formation of bubbles?

This falls under the umbrella of physicochemical research. If not carbon dioxide, but a chemical reaction.

So how the chemical reaction starts, the principle is the same.

Generally speaking, the most common physical and chemical dehumidification is to use silicone gel to dehumidify. It takes advantage of the porous structure and hydrophilicity of silicone gels.

Adsorption of moisture. In addition, cooling dehumidification, liquid dehumidification, etc. are all physical and chemical dehumidification methods.

The phenomenon of moisture resurgence in daily life was analyzed, and the physical and chemical principles contained in indoor dehumidification were analyzed by taking air-cooled refrigeration dehumidifiers, air conditioners and rotary dehumidifiers as examples. Steer.

Physical dehumidification is done by blowing air (drying), heating and evaporation.

Chemical dehumidification is done through some desiccant (which can react with water to absorb water), such as calcium oxide, anhydrous calcium chloride, soda lime and concentrated sulfuric acid.

Use fire to burn, and when it is dry, it is physically dehumidified.

Physical and chemical dehumidification is to use silicone gel to dehumidify. It uses the porous structure and hydrophilicity of silicone gel to adsorb water.

The principle of dehumidification of air conditioning is to use the low temperature generated by the air conditioner to condense the water vapor in the indoor air into liquid water and discharge it outside.

1. Dehumidification is a secondary function of the air conditioner (not ***).

The principle is that when high-temperature air with water vapor flows through the low-temperature evaporator heat sink, water condenses out. Of course, this process also happens during the refrigeration process, and the water is condensed and discharged through the drain pipe, so the dehumidification temperature will be relatively high.

2. Cooling is to take away the heat by vaporizing the refrigerant in the indoor evaporator of the air conditioner, and the indoor air flowing through the radiator of the Ludan evaporator is cooled by accompanying Chang Disturbance.

The vaporized refrigerant is compressed and liquefied by the compressor to release heat outdoors and transfer the heat to the outdoor air through the heat sink. In this way, the continuous circulation achieves the effect of indoor air cooling. The control circuit of the air conditioner has air temperature detection, and when it detects that the indoor temperature reaches below the set temperature, the compressor will stop working and enter the constant temperature control state.

In addition, with diet, eat more foods that promote dampness and strengthen the spleen, such as: red adzuki beans, red beans, barley, mung beans, winter melon, yams, white radish, red dates, kelp, etc., or drink thin barley and red bean tea.

There are cupping, scraping and other methods of dampness in the body, but the effect is not necessarily ideal, and the dampness in the body still needs to be used in traditional Chinese medicine. For the internal arrest of dampness in the body, traditional Chinese medicine believes that it is caused by eating more cold food or the weakness of the body's spleen and stomach. Suggestions:

In normal times, it is necessary to avoid eating cold drinks or raw and cold foods to prevent aggravation of diseases, and comprehensive ** should be adopted.

Opinions and suggestions for late completion: In normal times, it is necessary to avoid eating cold drinks or raw and cold food to prevent aggravation of disease and fatigue disease.
