What is a fresh air system? What is the classification?
What is the fresh air system? This is the first question that may be asked when you first come into contact with the fresh air system. The fresh air system is a continuous and efficient 24-hour uninterrupted cycle of indoor and outdoor air throughout the house. It is an air replacement system that guarantees indoor air quality. It ensures that there is fresh air in the room all the time, and it is nicknamed "the respiratory system of the house."
The fresh air system can be roughly divided into the following three categories: a semi-mechanical negative pressure fresh air system (one-way), a full mechanical fresh air system (two-way), and a multi-point mechanical positive pressure air supply system.
Semi-mechanical negative pressure fresh air system
The semi-mechanical negative pressure fresh air system is also called the one-way fresh air system in the industry. It exhausts the air through the fan, causing negative pressure inside the room, and drives the outdoor air to slowly flow into the room through the air inlet of the living room, living room, bedroom, etc., dirty. The air is discharged to the outside through the exhaust vents of the bathroom, etc., to achieve the purpose of changing the indoor air quality.
Features: The duct and power are the least, simple, efficient, comfortable, economical, easy to clean, no secondary pollution. Suitable for families, small office buildings, apartments, hotel rooms, hospital wards.
2. Fully mechanical fresh air system
The all-machine fresh air system is called the two-way fresh air system in the industry. It is divided into two cases: an energy-saving all-machine fresh air system with cold and heat exchange, which can recover 70% of the heat. Another fully mechanical fresh air system without cold and heat exchange. There are power and pipelines at the air inlet and exhaust vents, and air and exhaust air are sent to the room through machinery and pipes, and the amount of air exchange is large. Suitable for public places, where people gather.
3. Multi-point mechanical positive pressure air supply system
The whole system has only the air inlet, and only the fan is installed at the air inlet, forcibly blowing air into the house, forming a positive pressure, and the flow of the dirty air is not considered, forcing the dirty air to be discharged from the window slit, the door seam, and the like.
