Notes when installing ventilation systems for construction

For high-rise buildings, factories, workshops... today, installing a duct system is considered a mandatory task.

The duct system ensures the circulation and movement of air in a fixed space to provide a source of clean air for the living environment in that space.

Areas such as high-rise buildings, factories, workshops are very closed spaces, air circulation is very difficult, so it is necessary to install a duct system to circulate air. In addition to air circulation, the duct system combined with industrial ventilation fans from the air vents brings a fresh and clean atmosphere, avoiding suffocation, increasing the risk of respiratory diseases.

Duct systems are divided into two main types: including natural ventilation systems and mechanical ventilation systems:

• With natural ventilation systems, people can design them themselves when building, design through equipment mounted on the roof or windows such as fans and vents.

• For mechanical ventilation systems, this is a specialized system for factories that often requires a lot of technical skills from highly skilled refrigeration technicians. This ventilation system will actively draw in air from outside and push the existing air in the house out into the environment.

Depending on the conditions and installation terrain of each factory, the duct system design and layout are different. People can install the system on the ceiling, roof or basement ventilation system, manufacturing plants, petrochemical refineries, etc. When designing the duct system, it is necessary to note the following basic steps:

The first thing to do is calculate the amount of air flow needed to supply and exhaust to choose the most suitable factory ventilation fan.

Next, draw a diagram of the duct system, determine the installation location in the appropriate positions. If the space for installing your duct system is not enough, you can increase the size of the vents, instead of trying to arrange many vents on the ventilation pipe. Without calculation and consideration, it will be difficult to solve the problem of stagnant air inside the area that needs to be installed without being able to circulate, so installing an industrial ventilation fan is a wrong decision.

Note that when installing a large capacity exhaust fan, it is necessary to choose an industrial electric fan with low noise, the fan must run smoothly, otherwise the noise in the factory will be very loud, causing noise pollution, affecting the production process.

Installing a duct system is extremely necessary in every construction project, they make the installation area cooler and create a fresh atmosphere for people living and working there. That is why ductwork installation is very necessary, so it is necessary to pay careful attention before installing the duct system.
