Give home N95 level protection, home fresh air system, real breathing enjoyment!
After the epidemic, the fresh air system once again refreshed people's understanding. The fresh air system can not only provide 24 hours of uninterrupted ventilation and ventilation, its filtering function, but also reduce the entry of outdoor bacteria and avoid cross infection. After this incident, I believe that the fresh air system will gradually become a standard package for primary and secondary schools, real estate, and public places.

As our lives and work are gradually on the right track, many people continue to work on renovations that were not possible in the spring. Don't be entangled, the home fresh air system will be arranged sooner or later, and installed as soon as possible to ensure the health of the indoor home. The following three aspects explain how the fresh air system guarantees clean and healthy indoor air:

1 / Farewell to spring sleepy, you need a little fresh wind

Frequently open doors and windows in spring to maintain the circulation of fresh air in the room to increase oxygen content and reduce harmful gases such as carbon dioxide, which can alleviate the occurrence of "spring sleepiness". However, due to the haze, outdoor dust, and air pollution, indoors often cannot guarantee window ventilation. The fresh air system meets this demand. It can ensure effective fresh air and increase indoor oxygen content without opening the window.

The central fresh air system can provide independent fresh air purification solutions for individual rooms by rationally designing pipes and air outlets. By continuously introducing outdoor fresh air, it can solve the problems of air turbidity and increased CO concentration caused by indoor ventilation.

Similarly, the fresh air system can effectively improve the occurrence of "air conditioning disease" when the air conditioning is turned on in summer.

2 / The fresh air system effectively isolates external pollution

The fresh air system filters the outdoor air heavily, purifies the pollutants in the air, and then introduces them into the room, which can effectively isolate external pollution. The fresh air system will maintain a certain pressure difference between the indoor and the outdoor, and isolate the outdoor air from the doors and windows, and can only enter through the fresh air inlet, thereby isolating the external pollution. In cities with harsh environments and outdoor haze, such as Beijing, Henan, Hebei, Shandong, and Northeast, where the air pollution index is frequently reported, it is recommended to install a fresh air system.

3 / N95 grade HEPA filter effectively filters bacteria and viruses

During the epidemic, we all know that N95 masks can effectively isolate virus transmission. N95 masks have a high filtration efficiency, and N95 masks have a filtration efficiency of not less than 95% for 0.3 micron particles. The HEPA filter widely used by the fresh air system is equivalent to wearing a large "N95 mask" for the home space, effectively filtering and purifying bacteria and viruses. The HEPA filter is a high-efficiency filter, which requires a filtration efficiency of at least 99.97% for PM0.3 (particulate matter with a diameter of about 0.3 microns).

Viruses are parasitic in a cell, and only microorganisms such as bacteria can provide parasitic conditions for viruses in the air, and all airborne microorganisms are attached to aerosols in the air, such as droplets and particles. The diameter of the droplets is more than 10 microns, and the diameter of our best-known PM2.5 is also about 2.5 microns, so whether it is a carrier that intercepts viruses, or particles such as catkins, pollen, dust, etc. in the air, the HEPA filter has Interception effect.

Choose a fresh air system to give your home "N95" level of protection. The indoor fresh air system specializes in creating clean home spaces.Is it necessary to install the fresh air system recommended during decoration Where are the people who have been eating ash for many years but are secretly happy this year
Is it necessary for ordinary families to install fresh air system? The circulation of indoor air depends on the windows, but in special cases, such as smog, sand, air conditioning, or no windows in the room, what should I do in a severe epidemic in 2020? Meichao tells everyone how the new air system that has been popularized by the niche and can meet the indoor air circulation works. How should ordinary families choose?

First, introduction of fresh air system

In modern smart homes, the air purification system is constantly improving, overcoming many different points, and connecting the large environment of smart home life to form a unique fresh air system. His design principle is to filter the pollutants in the air, just like the lungs of the human body, mainly including particulate matter such as smoke and dust. Generally speaking, it is two-way ventilation management, which can mechanically help indoor and outdoor air exchange, especially for people living in underground buildings, it is a must-have in the home, reducing the bacteria that may be caused by long-term air deposition, which is harmful to human health. Causes subtle damage. In layman's terms, the fresh air system is to filter and disinfect the outdoor fresh air into the room; then the indoor dirty air is discharged out of the room to achieve a process of indoor fresh air.

Second, the composition of the fresh air system

Generally speaking, the fresh air system does not independently handle the indoor air circulation, but continuously updates the indoor air environment through the air intake system and the exhaust system. Through the installation of ventilation pipes, it is divided into Home ventilation and ventilation systems in public places. The system with pipes installed on the wall is more suitable for purifying the smell of the air in public places because of its large exhaust volume and higher power; while the design without pipes, the purification efficiency is relatively low, and it is more suitable for small fixed spaces in homes In this way, the intelligent air purifier can play a good use in the air filtration process, and it is also very effective for saving daily electricity.

Third, the operating principle of the fresh air system

The fresh air system is composed of a fresh air ventilator and pipe accessories. When the ventilator is running, the dirty air passes through the air inlet fan, and under the effect of the filtration and purification system and the energy exchange system, clean and fresh air is input into the room to satisfy the family. The needs of the activities, and the indoor air is directly discharged from the exhaust fan after the action of the energy exchange system to ensure the purpose of indoor air purification. Air exhaust and air supply equipment should be placed at both ends of the home to prevent the fresh air from being invited but then invited out. Such air purification efficiency will be greatly reduced.

Fourth, the choice of fresh air system type

At present, there are three different types of fresh air systems, which can be identified and selected for different forms of indoor environments:

1. Unidirectional flow

That is, the ventilation system is divided into single-in or single-out. Generally speaking, there are more single-out, because the air is not like loose sand and liquid. As long as it is continuously discharged, the outside air can certainly be replenished in time. The supplementary method is not as efficient as the two-way type. The general unidirectional fresh air system is composed of three parts: a fan, an air inlet and an air outlet. It is like a simple lung structure, which can meet the natural breathing and ventilation in the room in daily life. Many home ventilators, that is, basic one-way flow ventilation equipment, compared with other products of fresh air system, have the advantage of higher cost performance and more convenient installation.

2. Two-way flow

The design of the two-way flow is to connect the pipes to the indoor "air distributor", one row at a time, to meet the fresh and quality air that people need in daily life, and to supplement one-way flow with many key functions. The two-way design of the exhaust port and the new air port are equipped with valve ports that can adjust the component. For different sizes of space, the interaction between the two is completed through the same system in the host.

3. Ground air supply system

Carbon dioxide is heavier than oxygen, so the closer it is to the ground, the lower the oxygen content in the air. The ground air supply system delivers fresh air from the outside through the solid wood floor or wall, stirring the carbon dioxide gas deposited at the bottom to play the most efficient way of air circulation. However, the ground air supply system has very restrictive requirements. It can only improve the oxygen concentration of the indoor air, but it is helpless to pollutants and bacterial particles in the air. The most prominent advantage of this design is that it will reduce the dust on the floor and live. Many of the dust in the area contains bacteria and infectious viruses. No matter how bad it is, it will make people with nasal allergies feel uncomfortable and relieved.

In the current environment, we can't open the window at will, and we have a new interpretation of the fresh air system. Please carefully understand and make the right choice.
