Nowadays, air ducts are becoming more and more necessary for construction projects. However, not everyone understands this system, especially with small installation models. So in this article, Sao Viet Air Duct will share with you more detailed information about air ducts as well as ventilation systems.
1. Air duct
Air ducts are pipes that are usually made from galvanized sheet metal.
Designed in many different shapes and sizes. The most popular types are round ducts (each section is 4m), square ducts (each section is 1.2m), rectangular ducts, etc.
Role of air duct:
– Air ducts help provide fresh air from outside, while pushing exhaust air from inside the building out. Especially carbon dioxide – a substance harmful to the respiratory process.
– Air ducts also contribute to providing oxygen to help balance human life.
– In addition, air ducts are also used to overcome other problems such as: spreading toxic substances, fires, etc.
2. Ventilation system
The ventilation system consists of many ducts connected together to exchange air with the outside. This system is widely used from small environments such as in the family, to large projects such as in factories, offices, etc.
The ventilation system acts as an air conditioning system, helping to replace stuffy air with fresh air.
The system also has the ability to control temperature, remove dust, odors, mold, etc., helping the atmosphere become cool, fresh, and good for human health.
3. Classification of ventilation systems
Depending on the classification, ventilation systems can be divided into many different types. Specifically, there are 4 classifications as follows:
3.1. Classification according to wind direction: 3 types
– Blower type ventilation system: Due to the pressure difference, clean air from outside will be brought in through the gaps. However, because the pressure in the room is always positive, the wind can flow in all directions, even in unwanted places.
– Exhaust ventilation system: This type will use the system to exhaust dirty air from inside the room to the outside. At the same time, outside air will flow into the room through gaps or from windows to get fresh air. This type of system has the ability to directly suck polluted air in the space, preventing the spread of air to the surrounding area. However, they have the disadvantage of causing low air circulation in the room, not to mention the air flowing in from outside will not be able to be controlled.
– Combined ventilation system: This is a combination of the above two types. This type of system will both draw clean air into the room and exhaust all dirty air out. Therefore, this method is considered the most effective and has few disadvantages. However, the cost of owning this ventilation system will be higher.
3.2. Classification by organizational method: 2 types
– Overall ventilation system: This type of system will ventilate entire rooms or entire buildings.
– Local ventilation system: This type of system only ventilates a designated area or an area that is contaminated with toxic air.
3.3. Classification according to the driving force of ventilation: 2 types
– Natural ventilation system: This system will use the pressure difference to exchange air between indoors and outdoors.
– Forced ventilation system: This system will create a force to the ventilation process by using a fan.
3.4. Classification by purpose: 2 types
– Normal ventilation system: This system is used to remove harmful substances, and provide fresh, clean air for indoor spaces.
– Emergency ventilation system: This system is used to handle possible incidents so that timely response methods can be provided. For example, chemical spills or unexpected fires.
Above is some information that you should not ignore when you need to learn about air ducts and ventilation systems.
