The Fresh Air System Design Attentions

To make the air convection smooth, air volume = fresh air.

The size of the building: residential indoor breathing vertical height of 2.4 m; Commercial building breathing activity for the vertical height 4.5 m, the rate of breathing area of the whole space is about 0.26 to 0.26.

Residential, office buildings, the new air volume can not be lower than 30 m3 / h.p. Considering air changes and new air volume, take the fresh air volume for calculating the maximum to select the target model.

Sports venues, large conference hall, theater, etc., consider the exchange times of the fresh air to select the model, if people stay under 3 hours, take 50% attendance to determine the new air volume.

For shopping mall, take 30% of the total supply of central air conditioning system to determine the model selection.

Factory, workshop and other places of poisonous and harmful matter, the model selection is base the required air volume for attenuation and also consider the ventilation rate.

The Characteristics of The Fresh Air System

1. Health: organized ventilation, 24 hours a day, 365 days continuous ventilation;

2. Efficient: improve the oxygen content, in addition to the peculiar smell and formaldehyde

3. The mute: ultra-quiet fan, do not affect life and sleep within (24 db);

4. Energy saving: the average daily consumption is about 0.7 degrees of electricity;

5. Quality: can the continuous running 160000 hours continuously (20 years)

The significance of ventilation:

Outdoor air filtered into indoor, don't open the window also can enjoy the fresh air of nature

Must stay healthy, high quality of plenty of fresh air.

Effective eliminate indoor bad smell, all sorts of bacteria, viruses, as well as from the inside and outside all sorts of pollution.

The harmful gas of low long-term slow-release after removal of interior decoration, formaldehyde, benzene, ammonia, etc.

Prolonging the life of the building and furniture, to prevent mold.

Low to avoid air conditioning for the elderly, children and family health damage.
No effective products on the Chinese market, at the same time solve the problem of indoor air quality and pollution.

After adequate food and clothing of the Chinese people, pay attention to health is a kind of trend.

Comprehensive indoor air pollution problems, the effective solution is half of the mechanical pressure ventilation.

Practice has proved that half mechanical negative pressure ventilation system have been agreed upon by many developed countries in the world, and widely used for a long time.

The ventilation system is changing:

Nowadays, the ventilation system is not only about exhaust and exchange the air with indoor and outdoor, it could be worked with a lot of different needs, in summer, when the temperature is hot, people is using AC more often, however it's hard to exchange the indoor air with outdoors with no temperature loss, however, that's solved when Heat Exchanger is born. With this device, people can enjoy the comfortable temperature with the fresh air in the same time.

The Fresh Air System Design Principle

The indoor air quality directly affect people's health, advanced central fresh air system based on three principles of design.

First: The fresh air goes through the living and bed room, and exhaust through the pollution air like bathroom, toilet and kitchen.

Second: To satisfy people's daily work and rest with enough fresh air and energy saving within the same time.

Third: 365 days a year, 24 hours a day uninterrupted ventilation. Central fresh air system, drainage preservation, create pure and fresh living conditions, clean the bedroom environment, while ensure people’s health, environmental protection, safety, and give attention to energy saving and humanization.

The living condition is very important to every one who lives in it, especially those elder people and children, every breath will affect their health, as today, with the sharp development of economy, the serious pollution and frequent attack of haze has made the indoor air quality worse and worse. Environment improvement has become the consensus of human. And this is why people are paying more and more attentions on fresh air systems, some countries carried out the clause that every home must equipped the ventilation system so called fresh air system.

What is Fresh Air System

In pursuit of health and ease the quality of life, 70 years ago in European countries a simple and practical system was built at the historic moment, 90% of their buildings were installed this system, at present, it has been widespread in a lot of situations, that's the central fresh air system.

The system continuously for the whole house 24 hours a day by circulating the air from indoor and outdoor, it is an air exchange system to ensure the quality of indoor air conditions.

To ensure the indoor always have the fresh air, so it's called "houses of the respiratory system".
