What is the working principle of the fresh air system?

2023-05-04



The fan of the fresh air system is connected to the exhaust outlet through a pipeline, and the fan is started. Indoor air is discharged to the outside, and outdoor fresh air enters the room. A flow layer of fresh air is formed indoors to achieve ventilation effect.


The principle of the fresh air system is as follows:

The fresh air system is an open circulation system composed of fans, air intakes, exhaust outlets, and various pipes and joints. The fan is connected to a series of exhaust outlets through pipelines, and the fan is activated to create negative pressure indoors. The polluted indoor air is discharged outdoors through the exhaust outlet and fan, and fresh outdoor air enters the room through the inlet. Maintain indoor circulation of fresh air at all times, allowing people to breathe fresh, clean, and high-quality air indoors
Generally speaking, the fresh air system is to install a special equipment in one corner of the confined space, which supplies fresh air indoors. At the same time, the other side also uses special equipment to exhaust indoor air to the outside. Through this method, a flow layer of fresh air will be formed indoors, achieving the effect of ventilation.
The fresh air system is based on using specialized equipment to supply fresh air indoors on one side of a closed room, and then discharging it outdoors from the other side. This creates a "fresh air flow field" indoors, thereby meeting the needs of indoor fresh air exchange. The implementation plan is to use high air pressure and high flow fans, rely on mechanical strength to supply air from one side indoors, and use specially designed exhaust fans from the other side to exhaust air outdoors to force the formation of a new airflow field in the system. Filter, disinfect, sterilize, oxygenate, and preheat the air entering the room while supplying air (in winter)
It can be seen that the fresh air system has the advantages of providing fresh air, removing harmful gases, preventing mold and odor, reducing noise pollution, and dust prevention. Among them, the fresh air system can operate 24 hours a day without interruption, providing fresh air to the indoor environment every day.
