Description

A plasma fresh air system

technical field

The invention relates to the technical field of air purification, in particular to a plasma fresh air system.

Background technique

With the rapid development of global industrialization, the environment has been destroyed, leading to the deterioration of environmental quality.

Modern people live and work more than 90% of the time indoors, and indoor air pollution is more serious than outdoor, which can easily lead to illness. The main factors that lead to illness are harmful gases, tiny particles and pathogenic microorganisms that exist in the air.

Among them, harmful gases include formaldehyde, benzene compounds, ammonia, volatile organic compounds, etc.

1) High concentrations of formaldehyde are toxic to the nervous system, immune system, liver, etc. Long-term exposure to higher concentrations of formaldehyde can cause acute mental depression.

2) Long-term exposure to low-concentration benzene series compounds may cause chronic poisoning, thrombocytopenia, leukopenia, and severe bone marrow hematopoietic dysfunction.

3) Long-term exposure to low-concentration ammonia may lead to dyspnea, pulmonary edema, coma or shock.

4) Indoor total volatile organic compounds (TVOC) mainly come from paints, aqueous coatings, adhesives, etc. Thousands of TVOCs have been found indoors, which are extremely harmful to the human body.

Tiny particles: Suspended particles floating in the atmosphere for a long time, also known as inhalable particles, inhalable dust or floating dust. Particles with a particle size larger than 10 microns are usually deposited in the respiratory tract, and tiny particles with a particle size of 5 microns can enter the deep part of the respiratory tract, especially tiny particles with a particle size of less than 2.5 microns can directly enter the bronchi and alveoli, causing great harm to the human body. The smaller the particle size, the deeper the part that enters the respiratory tract, and the more serious the harm to the human body.

Pathogenic microorganisms: pathogenic microorganisms that can cause diseases in humans, animals and personnel.

Microorganisms that exist in the air, including bacteria and viruses, often attach to the surface of tiny particles and spread various infectious diseases.

In this case, various fresh air systems and air purification products for air purification stand out, trying to improve our living environment, especially the indoor environment, through fresh air systems or air purification equipment.

Therefore, the fresh air system has gradually become a necessity for a healthy life.

1) In the newly renovated house, chemical gas invades our body, and we have to open and close the windows every day;

2) Even after living for several years, toxic and harmful gases still plague our lives;

3) There is a lot of dust in the room, mosquito bites, noise, etc. affect our rest and study;

4) Rainwater, dust, thieves, and children will make people worry after the window is opened;

5) Water vapor accumulates, clothing and valuables are prone to mildew and damp;

6) Cigarettes in the room, lampblack in the kitchen, and peculiar smell in the bathroom;

7) The lack of ventilation caused by the room type is dark, and there are no north-south windows;

8) Tiredness, headache, blushing, and drowsiness in air-conditioned rooms, commonly known as "air-conditioning disease";

9) The impact of SARS and other airborne diseases on people's health awareness;

10) The promulgation and mandatory implementation of relevant laws and regulations such as indoor pollution control norms, fresh air volume requirements for small central air conditioners, etc.
