The fresh air system is an important link in the purification and decoration project of the workshop. How much do you know about the fresh air system? If you don't know much about it, the following will introduce the fresh air system in the purification and decoration project of the workshop in detail from the ventilation principle, ventilation type and equipment function.

I. ventilation principle of fresh air system
Discussion on the fresh air system in the purification and decoration project of workshop
1. introduction. The so-called fresh air system, simply speaking, is an independent air treatment system, which consists of two parts: air supply system and exhaust system. In 1935, Auston Chun made the world's first heat exchange equipment capable of filtering air pollution, which is the world's first fresh air system.
2. principle. Take the decoration of the clean workshop of the factory as an example, an air supply system is installed on one side of the airtight room to supply fresh air to the clean room; an exhaust system is installed on the other side of the airtight room to exhaust the exhaust gas in the clean room, so as to form a "new air flow field" in the clean room, so as to meet the needs of fresh air exchange.
II. Ventilation type of fresh air system
1. Divided by air supply mode. It can be divided into three types: one-way flow fresh air system, two-way flow fresh air system and ground air supply system.
2. According to the installation mode. It can be divided into two categories, i.e. pipeline fresh air system and single fresh air system.
3. According to ventilation power. It can be divided into two categories: natural ventilation and mechanical ventilation.
4. According to the scope of ventilation service. It can be divided into two categories, i.e. overall ventilation and local ventilation.
5. According to the air flow direction. It can be divided into two categories, namely: supply (inlet) and exhaust (smoke).
6. According to ventilation items. It can be divided into six categories: general ventilation, hot air heating, detoxification and dust removal, accident ventilation, protective ventilation, building smoke control.
7. According to the location of power. It can be divided into two categories: centralized power and distributed power.
8. By style. It can be divided into four types, namely: vertical cabinet (floor type), cabinet type, wall hanging type and ceiling type.
III. equipment function of fresh air system
1. Keep the air clean. The fresh air system can maintain the air cleanliness of the factory clean workshop, which is also the main equipment function of the fresh air system.
2. Maintain indoor comfort. The fresh air system can maintain the comfort of the clean workshop of the factory and provide a comfortable office environment for employees. This function is also called "thermal comfort ventilation".
3. Adjust the indoor and outdoor temperature. When the temperature in the clean workshop is higher than the outdoor temperature, the indoor and outdoor temperature can be adjusted through the fresh air system.
I believe that through the detailed explanation above, we have a certain understanding of the fresh air system of the factory clean workshop decoration. Finally, if you want to know more about clean workshop decoration, you can click clean Engineering, which will help you.
