HC air-conditioning refrigeration network news in the north to open the heating is essential, although the heating brings warmth, but also brings heating disease, what is the heating disease? "Heating disease" mainly refers to heating in winter. The immune function and resistance caused by the environment and the dryness and lack of water of the human body are reduced, resulting in different degrees of internal heat and cold symptoms. Dry mouth, dizziness, sore throat, cough, irritability, skin tightening, etc., which are often seen during heating, are medically known as "heating diseases." Due to the strong airtightness of the heating room, the tightness of the doors and windows leads to poor air circulation, and the sun does not open when the window is not opened for a long time. This makes the humidity and temperature conditions of the room become a hotbed of pathogenic factors, and various microorganisms such as mold, bacteria and viruses are proliferated and parasitic on bedding, carpets, curtains and furniture. In such an environment, a large number of microorganisms breed and are susceptible to diseases caused by microorganisms, and the human body is more susceptible to diseases.
The understanding of the fresh air system is deeper with the smog. The fresh air system not only ventilates the indoor air, but also removes indoor odors and harmful substances, while maintaining indoor air humidity, and can also prevent influenza. The smog is the key factor for the fresh air system to enter the ordinary family. The smog in the south is slight, so there are very few people who know the fresh air system. Most people have never heard of it, but the living environment in the south is not only compared with the north. Even more serious, the humidity in the rainy weather, in this season, most of the buildings in the south will be "flowing tears", the humidity is particularly heavy, and the fresh air system can accelerate the flow of air, the indoor humidity is fast discharge.
In addition, the indoor and outdoor air pollution levels are similar in the north and south. The fresh air system integrates ventilation and air purification to prevent influenza, remove indoor formaldehyde, benzene and other decorative materials, and release harmful substances from building materials, purify indoor air, and discharge soot. Second-hand smoke and carbon dioxide have played a huge role in improving people's quality of life. In the north, the haze is more aware of its role due to the smog. The haze is only an entry point. In fact, the fresh air system is necessary in both the north and the south.
