Haze will harm people's respiratory health has been a cliche, and in order to avoid haze in haze weather, people generally choose to hide in the home with closed doors and Windows, so that the house is isolated from the outside world, so as to protect themselves from the harm of haze.

However, indoor pollution is often more serious than outdoor pollution, it can be said that we humans have nowhere to hide in the face of air pollution.

Faced with severe indoor air pollution, people urgently need to create a safe indoor breathing environment for themselves.

A little health protection awareness of consumers will buy an air purifier placed at home, when the home pollution value exceeds the standard, open to purify the air, in order to create a healthy indoor air environment.

But obviously, this is not a goal that can be easily achieved by buying an air purifier.

First, the air purifier only opens for purification when the pollution value exceeds the standard, so it is too late, indoor pollutants have already harmed the human body;

Second, the air purifier is only the circulation and purification of indoor air, and can not solve the problem of indoor hypoxia, indoor personnel will gradually feel dyspnea, chest tightness asthma, lack of spirit, lack of concentration and a series of adverse reactions.

To solve this problem, it must be a fresh air system!

Everyone has heard of the fresh air system, which is a set of air circulation equipment to keep the indoor air in the house fresh and comfortable. Do you know what kinds of fresh air systems are available? What is the difference between good and bad? So this time I'll give you more knowledge.

So far, the fresh air system on the market can be generally classified into four categories according to the installation method, which are: ground air supply, suspended ceiling type, vertical cabinet type and wall mounted.

First, the ground supply air fresh air system

Advantages: Because carbon dioxide is heavier than air, the oxygen content is lower the closer to the ground. From the perspective of energy saving, the fresh air system installed on the ground will get better ventilation effect.

Disadvantages: The new air is sent from the lower part, which will blow the lighter dust on the floor back to the upper space to occupy the internal space; The ground air supply system needs to add air supply risers, which will occupy a certain internal space. High energy consumption, air ducts are generally made particularly flat, increase the air supply resistance, improve the energy consumption of new fans; The cost is high and the construction is difficult.

Family Recommendation Index: ★★★☆☆

Not recommended for general home installation.

Second, ceiling type fresh air system

Advantages: large air volume, duct can organize air flow, good air displacement effect; The overall effect is beautiful, and the whole house fresh air can achieve integrated operation.

Disadvantages: The house must take the pipeline, and the installation is complex, reduce the height, has been renovated houses or old houses can not be installed; The annual cleaning and replacement of consumables are more laborious, and the maintenance is troublesome in the later stage; Prices are generally expensive.

Family Recommendation Index: ★★★☆☆

Newly renovated villa families can be installed, the average family chooses to install on demand, generally not recommended.

Three, cabinet type fresh air system

Advantages: The main engine of the cabinet fresh air system has large power, large air supply area, highly integrated multiple purification and filtration modules, and high air cleanliness.

Disadvantages: The multiple purification and filtration module weakens the air volume and pressure to a certain extent, and the air displacement effect is reduced; The volume of household refrigerator occupies a lot of house area; Multiple rooms are needed to meet the needs of house purification.

Family Recommendation Index: ★★★★☆

Cabinet type fresh air covers a large area, and the average family chooses to install it on demand.

Fourth, wall-mounted fresh air system

Advantages: low noise, high flexibility, space saving, simple maintenance, users do not have to worry about affecting the house design or delay due to house decoration, because the wall-mounted fresh air does not need to arrange any line of the new fan, convenient installation, only need to punch two holes in the wall can be easily done.

Disadvantages: The suitable place is more single, suitable for family or small venues; It also needs a multi-room multi-unit purchase scheme to achieve air purification effect.
