What is ventilation about? Why ventilate frequently?

Ventilation is related to indoor odors, indoor environment, and some viruses. Frequent ventilation is more conducive to maintaining the clarity of the indoor environment, avoiding excessive inhalation of carbon dioxide, and can also avoid the inhalation of some harmful gases and the breeding of some bacteria.

Ventilation is related to the indoor environment, regular ventilation can keep the air in the house fresh and circulating, remove odors, sterilize, improve the air in the house, and so on.

This is because ventilation can make the indoor air circulating, and it can also make the indoor air fresher, so that there is more oxygen in the room, and it can also promote the metabolism of the human body, and will not let some bacteria and germs spread in the air.

Frequent ventilation can keep the indoor air fresh, frequent ventilation can prevent diseases, frequent ventilation can remove bacteria, frequent ventilation helps to breathe smoothly, frequent ventilation will bring a good mood.

This has something to do with maintaining environmental hygiene, so keep your home ventilated so that it will be more comfortable to live in.

There are four commonly used ventilation methods:

Open type (on the premise of meeting the requirements of functional and meteorological factors, it should be preferred).

Skylight ventilation (according to the production conditions, consider the facilities to prevent rain and sand).

Mechanical exhaust (explosion-proof motor is adopted, when the combustible substance or fibrous substance reaches a certain concentration, the explosion-proof motor is automatically turned on).

Exhaust hood exhaust (for buildings where flammable gases are lighter than air and tend to accumulate on top).

Diseases caused by indoor environmental contamination have become a public health problem that must be faced all over the world. Although air pollutants mainly exist outdoors, more than 80% of people's lives are spent indoors, and if there is no timely ventilation, formaldehyde, mold, carbon dioxide, dust, dander and other harmful substances floating in the air will increase, and fresh oxygen will continue to decrease.

Indoor spaces are often closed when sleeping, and after a whole night of breathing, the air in the bedroom is often a little bad, not only accumulating a lot of carbon dioxide, oxygen becomes very thin, and when tidying up the bedding, fine pollutants such as dust mites and socks and dander will float in the air. At this time, it is especially important to open the windows for ventilation.

1. The reason why the room should be ventilated frequently is mainly because the room is in a relatively closed state, and if it is not ventilated for a long time, the air will be more turbid, so that it is easier to make the indoor air worse, and regular ventilation can keep the indoor air fresh.

Frequent indoor ventilation can also prevent the spread of diseases, such as colds, new pneumonia and other diseases, which can ensure the safety of family members and themselves to a certain extent, and have certain benefits to human health.

In winter or summer, the indoor temperature is easy to be too cold or too high, so as to form a kind of indoor environment dull things trembling phenomenon, appropriate ventilation, can not only help to adjust the indoor temperature, but also to a certain extent to maintain the human body and mind happy.

2. The most direct and effective way is to open the window.

Opening windows is the most effective and direct way for people to ventilate indoors, because nature is the best purifier, which can help people keep the indoor environment fresh and healthy, but if they are afraid of cold, or the wind outside is relatively strong and hazy, then you can also borrow green plants or air purifiers to help people ventilate indoors.

3Maintain air quality and reduce the spread of disease.

Many people mistakenly think that the ward does not need ventilation, ventilation is more likely to lead to the spread of disease, but in fact, this is not the case, ventilation can make the air in the ward circulated, exchange with the outside air, keep the air fresh, and secondly, it can also help regulate the temperature and humidity in the room, increase the comfort of patients, is an effective measure to reduce indoor air pollution and reduce the spread of respiratory diseases.

4. Different seasons have different indoor temperature standards.

In general, the suitable indoor temperature is 18 to 25 and the humidity is 30% to 80% in winter. In summer, the indoor temperature is 23 to 28 and the humidity is 30 to 60 percent. Studies have shown that more than 95% of people feel comfortable in this range, so different seasons have different indoor temperature standards, depending on the actual situation.

The location of the window, the area of the window, the obstruction on the outside of the window, the direction of the wind, the speed of the wind flow, the obstruction inside the window nuclear damage, etc., will affect the quality of the indoor ventilation.

Environmental factors, ventilation conditions, room size, air humidity, air temperature, these factors are related.

It depends on the lighting and topography of the area. If the lighting is better, the ventilation is also better.
