Basements of apartment buildings or commercial centers are often designed underground. It is a place to park cars, equipment and machinery, fire prevention and fighting systems or goods to serve all human activities in the building. Therefore, this is a place that needs to be protected and ventilated. Installing a fan to supply fresh air to the basement will both ensure a good source of air for people when going into the basement, and keep equipment and equipment safe. prevent fire and other incidents caused by air pressure.

What is the fresh air supply fan for the building basement?

The basement air supply system  is a system consisting of industrial fans, axial fans, centrifugal fans, air pipelines, opening and closing valves… used in tunnels, apartment buildings, office buildings, etc. Commercial center or hotel… to absorb CO2, exhaust gases and circulate fresh air for the installed area, helping people live and work safely and comfortably.

Some outstanding roles of the fresh air supply fan

Ventilation and fresh air supply to the basement area is quite important. The role of the ventilation fan to supply fresh air in the basement, specifically as follows:

• Provide high quality air for the inside of the building.
• Control temperature, supplement oxygen, supply fresh air to the building.
• Remove some components, some harmful air emissions such as moisture, odors, smoke, heat, dust, bacteria in the air.
• Contributing to fire prevention, protection of property and lives of residents.
• Help people have enough good air, clean air to live. Even working effectively in the condition of soundstage, closed space.

Why is it necessary to install a fresh air supply fan for the building basement?

With the development of society, the density of houses and apartments is increasingly dense. In the natural environment, in hot conditions, it is easy to make people feel tired. One of the reasons for this is not enough fresh air.

Being in the basement is even more dangerous. The construction of a soundstage in an enclosed area without ventilation, often built on or next to the waste crater, water tank, gasoline, engine waste from the garage, etc., the accumulation of CO2 is inevitable.

If the CO2 gas accumulates for a long time, it will explode when it encounters an electric spark. Without a fresh air supply fan system, surely no one can live and do normal activities.

Therefore, for buildings with basements for parking or even for commercial centers, a fan system must be installed to provide fresh air. Only then can safe construction standards be achieved. This is also the number 1 priority in the design and construction of buildings by contractors and investors.

Working principle of the air supply fan system for the basement

The operating principle of the air supply fan system for the basement is mainly using a system of industrial centrifugal exhaust fans, axial fans, air supply ducts, opening and closing valves… with large capacity generating capacity. The forces of attraction and repulsion help air circulate in basements and buildings, both eliminating emissions and providing fresh air for people to live and work, Returning an almost natural living environment even in closed conditions.

Note when installing a ventilation fan to supply fresh air to the basement

In order to install a ventilation fan to supply fresh air to the basement in an efficient and cost-effective manner, the building management should note the following basics:

– Calculate space and choose a good ventilation fan, durable and suitable for the space of the basement.

– Choose a reputable unit of design, construction and installation of fresh air supply fans to be able to consult and install quickly, optimizing usage as well as installation costs.

– After selecting a construction design unit, it is necessary to combine to calculate and install according to the following steps:

Step 1: Sketch out the necessary ventilation pipe diagram going in the basement floor plan.

Step 2: Arrange the vents on the pipeline (the distance between the louvers and the supply/suction branch should be from 3m-6m) to ensure the effect of the louvers.

Step 3: Calculate the size of the air outlet

Step 4: Calculate the required air volume on the supply/suction branches and adjust the distance between the louvers to be reasonable for each branch.

How much does it cost to install a fan to supply fresh air to the building’s basement?
