Classified by air supply method
1、One-way flow fresh air system
The One-way flow system is a diversified ventilation system formed by combining central mechanical exhaust and natural intake based on the three principles of mechanical ventilation system. It is composed of fans, air inlets, exhaust outlets, and various pipes and joints.
The fan installed in the suspended ceiling is connected to a series of exhaust outlets through pipes. The fan starts, and the indoor turbid air is discharged from the outdoor through the suction outlet installed indoors, forming several effective negative pressure zones indoors. The indoor air continuously flows towards the negative pressure zone and is discharged outdoors. The outdoor fresh air is continuously replenished indoors by the air inlet installed above the window frame (between the window frame and the wall), So as to continuously breathe high-quality fresh air. The supply air system of this fresh air system does not require the connection of the supply air duct, while the exhaust air duct is generally installed in areas such as aisles and bathrooms that usually have suspended ceilings, and does not occupy additional space.
2、Bidirectional flow fresh air system
The bidirectional flow fresh air system is a central mechanical air supply and exhaust system based on the three principles of mechanical ventilation system, and is an effective supplement to the one-way flow fresh air system. and the design of a bidirectional flow system, the positions of the exhaust host and indoor exhaust outlets are basically consistent with the distribution of unidirectional flow, but the difference is that the fresh air in the bidirectional flow system is fed by the fresh air host. The fresh air host is connected to the indoor air distributor through pipelines, and continuously sends outdoor fresh air into the room through pipelines to meet people’s daily needs for fresh and high-quality air. Both the exhaust and fresh air outlets are equipped with air volume control valves, which achieve indoor ventilation through the power exhaust and supply of the host.
